Good news amp even better news for REES

In a stable grid environment no REES are needed below

60-70 REN in the grid (at least below 50)

However there are further business models for REES

bull Reduced FIT lead to big price gap between FIT and utility electricity prices

(buy expensive but sell cheap In Germany 28 Cent vs 11 Cent FIT vs 5-6 Cent production)

bull Back-up power systems can bdquoearn moneyldquo in stead of just beeing bdquoreadyldquo

(Battery back-up systems are quicker no pollution no noise)

bull Not all regions in the world have a stable grid

bull High Power EV Charging (150-350 kW) needs bdquobufferldquo solutions

bull Regions with flexible tarifs are already today

TUumlV SUumlD 06022018 28

Early bird markets for RESS

TUumlV SUumlD AG Slide 29Corporate Presentation14-01-22

At the moment

bull Markets are mainly driven by subsidies Eg Germany 1000 Systems installed in 201617

(40 subsidies)

bull Solar (and EV) enthusiasts who just like the idea of storing their PV harvest and use it at night or

charge it into their EV over night

bull Grid operators and utilities are testing the systems despite theylsquore not really needed as of today

bull Some regions have really bdquoweakldquo grid conditions (partly eg Italy)

bull Some regions already have flexible tarifs also for commercial and private customers

Early bird markets for RESS

TUumlV SUumlD AG Slide 30Corporate Presentation14-01-22

In the near future

bull Installations of REN still continue soarring Sooner or later there is an oversupply of electricity at

particular weather conditions while not all fossil powerplants can easily reduce or shut down

bull Countries aiming to become almost 100 supplied by REN soner or later enter a bdquocriticalldquo

transition phase where fast storage systems can guarantee power supply and stability of

frequency

bull If flexible electric power tarifs are getting bdquomainstreamldquo new business modell will pop up (Store

when cheap sell when expensive)

bull Storage systems can even make money without selling in a bdquocapacity marketldquo

Image ABB

Coming markets for RESS

TUumlV SUumlD AG Slide 31Corporate Presentation14-01-22

In the future

bull With increasing amounts of REN in the grid grid stabilization frequency stabilization becomes a

necessity

bull Seasonal storage solutions ndash together with P2G technologies ndash might become necessary in

regions with an unbalanced build up of REN (a lot of PV no wind or a lot of wind but no PV)

bull Regions without stabil external electric grid connection (eg Japan) might have additional needs

for energy storage solutions

Image Danish Wind Energy Association

Challenges of (residential) storage systems

bull Economic success depends on lifetime performance ndash 10 years plus

bull Local environmental conditions must be specified and testet ndash insideoutside operation

bull Sytems installed in the house have more stabil conditions

but saftety requirements and proof of product safety is key

to insurance companies ndash fire insurance

bull There are almost no existing safety regulations for inhouse installations of RESS

bull Serveral countries (eg Japan Germany) issued guidelines for RESS

bull Standards are evolving ndash dynamic environment

bull US standards are slightly ahead ndash eg UL 1973 ndash but various additional approvals are necessary

(eg NFPA 70 ANSIZ 535)

bull Third party test labs have set up various certification schemes eg TUV SUD Mark for RESS

Legal requirements

The legal requirements

are defined by the legislation eg European Commission or US authorities and

regionallocal requirements like from ldquoFire Safety Authoritesrdquo

belongs to products produced in or imported to the markets

are addressing system safety health and environmental protection

Storage systems must comply in the European Union with the CE marking regulations and

related directives in North America with the listing requirements and the national codes

With the CE-mark or listing mark the manufacturer his authorized representative or the

importer indicate that the product meets the legal requirements

Helpful for the manufacturers are the harmonized product standards Following this

standards compliance is presumed (eg IEC 63056)

For the USA a product standard is available (UL 9540) but further requirements need to be

met

TUumlV SUumlD 06022018 37

Global market access recommended strategy

TUumlV SUumlD AG Slide 38Corporate Presentation14-01-22

Basic steps of the strategy are

Step 1 Find the applicable directives standards and regulations

Step 2 Determine the applicable conformity assessment module

Step 3 Carry out a risk assessment define measures based on harmonized standards

(FMEA SIL FUSIhellip)

Step 4 Implement the measures defined at the risk assessment

Step 5 Create the technical file (TF)

Step 6 Declare conformity and do the CE-marking apply for UL 9540 compliance

Advantage

Good news amp even better news for REES

In a stable grid environment no REES are needed below

60-70 REN in the grid (at least below 50)

However there are further business models for REES

bull Reduced FIT lead to big price gap between FIT and utility electricity prices

(buy expensive but sell cheap In Germany 28 Cent vs 11 Cent FIT vs 5-6 Cent production)

bull Back-up power systems can bdquoearn moneyldquo in stead of just beeing bdquoreadyldquo

(Battery back-up systems are quicker no pollution no noise)

bull Not all regions in the world have a stable grid

bull High Power EV Charging (150-350 kW) needs bdquobufferldquo solutions

bull Regions with flexible tarifs are already today

TUumlV SUumlD 06022018 28

Early bird markets for RESS

TUumlV SUumlD AG Slide 29Corporate Presentation14-01-22

At the moment

bull Markets are mainly driven by subsidies Eg Germany 1000 Systems installed in 201617

(40 subsidies)

bull Solar (and EV) enthusiasts who just like the idea of storing their PV harvest and use it at night or

charge it into their EV over night

bull Grid operators and utilities are testing the systems despite theylsquore not really needed as of today

bull Some regions have really bdquoweakldquo grid conditions (partly eg Italy)

bull Some regions already have flexible tarifs also for commercial and private customers

Early bird markets for RESS

TUumlV SUumlD AG Slide 30Corporate Presentation14-01-22

In the near future

bull Installations of REN still continue soarring Sooner or later there is an oversupply of electricity at

particular weather conditions while not all fossil powerplants can easily reduce or shut down

bull Countries aiming to become almost 100 supplied by REN soner or later enter a bdquocriticalldquo

transition phase where fast storage systems can guarantee power supply and stability of

frequency

bull If flexible electric power tarifs are getting bdquomainstreamldquo new business modell will pop up (Store

when cheap sell when expensive)

bull Storage systems can even make money without selling in a bdquocapacity marketldquo

Image ABB

Coming markets for RESS

TUumlV SUumlD AG Slide 31Corporate Presentation14-01-22

In the future

bull With increasing amounts of REN in the grid grid stabilization frequency stabilization becomes a

necessity

bull Seasonal storage solutions ndash together with P2G technologies ndash might become necessary in

regions with an unbalanced build up of REN (a lot of PV no wind or a lot of wind but no PV)

bull Regions without stabil external electric grid connection (eg Japan) might have additional needs

for energy storage solutions

Image Danish Wind Energy Association

Challenges of (residential) storage systems

bull Economic success depends on lifetime performance ndash 10 years plus

bull Local environmental conditions must be specified and testet ndash insideoutside operation

bull Sytems installed in the house have more stabil conditions

but saftety requirements and proof of product safety is key

to insurance companies ndash fire insurance

bull There are almost no existing safety regulations for inhouse installations of RESS

bull Serveral countries (eg Japan Germany) issued guidelines for RESS

bull Standards are evolving ndash dynamic environment

bull US standards are slightly ahead ndash eg UL 1973 ndash but various additional approvals are necessary

(eg NFPA 70 ANSIZ 535)

bull Third party test labs have set up various certification schemes eg TUV SUD Mark for RESS

Legal requirements

The legal requirements

are defined by the legislation eg European Commission or US authorities and

regionallocal requirements like from ldquoFire Safety Authoritesrdquo

belongs to products produced in or imported to the markets

are addressing system safety health and environmental protection

Storage systems must comply in the European Union with the CE marking regulations and

related directives in North America with the listing requirements and the national codes

With the CE-mark or listing mark the manufacturer his authorized representative or the

importer indicate that the product meets the legal requirements

Helpful for the manufacturers are the harmonized product standards Following this

standards compliance is presumed (eg IEC 63056)

For the USA a product standard is available (UL 9540) but further requirements need to be

met

Good news amp even better news for REES

In a stable grid environment no REES are needed below

60-70 REN in the grid (at least below 50)

However there are further business models for REES

bull Reduced FIT lead to big price gap between FIT and utility electricity prices

(buy expensive but sell cheap In Germany 28 Cent vs 11 Cent FIT vs 5-6 Cent production)

bull Back-up power systems can bdquoearn moneyldquo in stead of just beeing bdquoreadyldquo

(Battery back-up systems are quicker no pollution no noise)

bull Not all regions in the world have a stable grid

bull High Power EV Charging (150-350 kW) needs bdquobufferldquo solutions

bull Regions with flexible tarifs are already today

TUumlV SUumlD 06022018 28

Early bird markets for RESS

TUumlV SUumlD AG Slide 29Corporate Presentation14-01-22

At the moment

bull Markets are mainly driven by subsidies Eg Germany 1000 Systems installed in 201617

(40 subsidies)

bull Solar (and EV) enthusiasts who just like the idea of storing their PV harvest and use it at night or

charge it into their EV over night

bull Grid operators and utilities are testing the systems despite theylsquore not really needed as of today

bull Some regions have really bdquoweakldquo grid conditions (partly eg Italy)

bull Some regions already have flexible tarifs also for commercial and private customers

Early bird markets for RESS

TUumlV SUumlD AG Slide 30Corporate Presentation14-01-22

In the near future

bull Installations of REN still continue soarring Sooner or later there is an oversupply of electricity at

particular weather conditions while not all fossil powerplants can easily reduce or shut down

bull Countries aiming to become almost 100 supplied by REN soner or later enter a bdquocriticalldquo

transition phase where fast storage systems can guarantee power supply and stability of

frequency

bull If flexible electric power tarifs are getting bdquomainstreamldquo new business modell will pop up (Store

when cheap sell when expensive)

bull Storage systems can even make money without selling in a bdquocapacity marketldquo

Image ABB

Coming markets for RESS

TUumlV SUumlD AG Slide 31Corporate Presentation14-01-22

In the future

bull With increasing amounts of REN in the grid grid stabilization frequency stabilization becomes a

necessity

bull Seasonal storage solutions ndash together with P2G technologies ndash might become necessary in

regions with an unbalanced build up of REN (a lot of PV no wind or a lot of wind but no PV)

bull Regions without stabil external electric grid connection (eg Japan) might have additional needs

for energy storage solutions

Image Danish Wind Energy Association

Challenges of (residential) storage systems

bull Economic success depends on lifetime performance ndash 10 years plus

bull Local environmental conditions must be specified and testet ndash insideoutside operation

bull Sytems installed in the house have more stabil conditions

but saftety requirements and proof of product safety is key

to insurance companies ndash fire insurance

bull There are almost no existing safety regulations for inhouse installations of RESS

bull Serveral countries (eg Japan Germany) issued guidelines for RESS

bull Standards are evolving ndash dynamic environment

bull US standards are slightly ahead ndash eg UL 1973 ndash but various additional approvals are necessary

(eg NFPA 70 ANSIZ 535)

bull Third party test labs have set up various certification schemes eg TUV SUD Mark for RESS

Legal requirements

The legal requirements

are defined by the legislation eg European Commission or US authorities and

regionallocal requirements like from ldquoFire Safety Authoritesrdquo

belongs to products produced in or imported to the markets

are addressing system safety health and environmental protection

Storage systems must comply in the European Union with the CE marking regulations and

related directives in North America with the listing requirements and the national codes

With the CE-mark or listing mark the manufacturer his authorized representative or the

importer indicate that the product meets the legal requirements

Helpful for the manufacturers are the harmonized product standards Following this

standards compliance is presumed (eg IEC 63056)

For the USA a product standard is available (UL 9540) but further requirements need to be

met

Good news amp even better news for REES

In a stable grid environment no REES are needed below

60-70 REN in the grid (at least below 50)

However there are further business models for REES

bull Reduced FIT lead to big price gap between FIT and utility electricity prices

(buy expensive but sell cheap In Germany 28 Cent vs 11 Cent FIT vs 5-6 Cent production)

bull Back-up power systems can bdquoearn moneyldquo in stead of just beeing bdquoreadyldquo

(Battery back-up systems are quicker no pollution no noise)

bull Not all regions in the world have a stable grid

bull High Power EV Charging (150-350 kW) needs bdquobufferldquo solutions

bull Regions with flexible tarifs are already today

TUumlV SUumlD 06022018 28

Early bird markets for RESS

TUumlV SUumlD AG Slide 29Corporate Presentation14-01-22

At the moment

bull Markets are mainly driven by subsidies Eg Germany 1000 Systems installed in 201617

(40 subsidies)

bull Solar (and EV) enthusiasts who just like the idea of storing their PV harvest and use it at night or

charge it into their EV over night

bull Grid operators and utilities are testing the systems despite theylsquore not really needed as of today

bull Some regions have really bdquoweakldquo grid conditions (partly eg Italy)

bull Some regions already have flexible tarifs also for commercial and private customers

Early bird markets for RESS

TUumlV SUumlD AG Slide 30Corporate Presentation14-01-22

In the near future

bull Installations of REN still continue soarring Sooner or later there is an oversupply of electricity at

particular weather conditions while not all fossil powerplants can easily reduce or shut down

bull Countries aiming to become almost 100 supplied by REN soner or later enter a bdquocriticalldquo

transition phase where fast storage systems can guarantee power supply and stability of

frequency

bull If flexible electric power tarifs are getting bdquomainstreamldquo new business modell will pop up (Store

when cheap sell when expensive)

bull Storage systems can even make money without selling in a bdquocapacity marketldquo

Image ABB

Coming markets for RESS

TUumlV SUumlD AG Slide 31Corporate Presentation14-01-22

In the future

bull With increasing amounts of REN in the grid grid stabilization frequency stabilization becomes a

necessity

bull Seasonal storage solutions ndash together with P2G technologies ndash might become necessary in

regions with an unbalanced build up of REN (a lot of PV no wind or a lot of wind but no PV)

bull Regions without stabil external electric grid connection (eg Japan) might have additional needs

for energy storage solutions

Image Danish Wind Energy Association

Challenges of (residential) storage systems

bull Economic success depends on lifetime performance ndash 10 years plus

bull Local environmental conditions must be specified and testet ndash insideoutside operation

bull Sytems installed in the house have more stabil conditions

but saftety requirements and proof of product safety is key

to insurance companies ndash fire insurance

bull There are almost no existing safety regulations for inhouse installations of RESS

bull Serveral countries (eg Japan Germany) issued guidelines for RESS

bull Standards are evolving ndash dynamic environment

bull US standards are slightly ahead ndash eg UL 1973 ndash but various additional approvals are necessary

(eg NFPA 70 ANSIZ 535)

bull Third party test labs have set up various certification schemes eg TUV SUD Mark for RESS

Legal requirements

The legal requirements

are defined by the legislation eg European Commission or US authorities and

regionallocal requirements like from ldquoFire Safety Authoritesrdquo

belongs to products produced in or imported to the markets

are addressing system safety health and environmental protection

Storage systems must comply in the European Union with the CE marking regulations and

related directives in North America with the listing requirements and the national codes

With the CE-mark or listing mark the manufacturer his authorized representative or the

importer indicate that the product meets the legal requirements

Helpful for the manufacturers are the harmonized product standards Following this

standards compliance is presumed (eg IEC 63056)

For the USA a product standard is available (UL 9540) but further requirements need to be

met

bull Economic success depends on lifetime performance ndash 10 years plus

bull Local environmental conditions must be specified and testet ndash insideoutside operation

bull Sytems installed in the house have more stabil conditions

but saftety requirements and proof of product safety is key

to insurance companies ndash fire insurance

bull There are almost no existing safety regulations for inhouse installations of RESS

bull Serveral countries (eg Japan Germany) issued guidelines for RESS

bull Standards are evolving ndash dynamic environment

bull US standards are slightly ahead ndash eg UL 1973 ndash but various additional approvals are necessary

(eg NFPA 70 ANSIZ 535)

bull Third party test labs have set up various certification schemes eg TUV SUD Mark for RESS

Legal requirements

The legal requirements

are defined by the legislation eg European Commission or US authorities and

regionallocal requirements like from ldquoFire Safety Authoritesrdquo

belongs to products produced in or imported to the markets

are addressing system safety health and environmental protection

Storage systems must comply in the European Union with the CE marking regulations and

related directives in North America with the listing requirements and the national codes

With the CE-mark or listing mark the manufacturer his authorized representative or the

importer indicate that the product meets the legal requirements

Helpful for the manufacturers are the harmonized product standards Following this

standards compliance is presumed (eg IEC 63056)

For the USA a product standard is available (UL 9540) but further requirements need to be

met

Good news amp even better news for REES

In a stable grid environment no REES are needed below

60-70 REN in the grid (at least below 50)

However there are further business models for REES

bull Reduced FIT lead to big price gap between FIT and utility electricity prices

(buy expensive but sell cheap In Germany 28 Cent vs 11 Cent FIT vs 5-6 Cent production)

bull Back-up power systems can bdquoearn moneyldquo in stead of just beeing bdquoreadyldquo

(Battery back-up systems are quicker no pollution no noise)

bull Not all regions in the world have a stable grid

bull High Power EV Charging (150-350 kW) needs bdquobufferldquo solutions

bull Regions with flexible tarifs are already today

TUumlV SUumlD 06022018 28

Early bird markets for RESS

TUumlV SUumlD AG Slide 29Corporate Presentation14-01-22

At the moment

bull Markets are mainly driven by subsidies Eg Germany 1000 Systems installed in 201617

(40 subsidies)

bull Solar (and EV) enthusiasts who just like the idea of storing their PV harvest and use it at night or

charge it into their EV over night

bull Grid operators and utilities are testing the systems despite theylsquore not really needed as of today

bull Some regions have really bdquoweakldquo grid conditions (partly eg Italy)

bull Some regions already have flexible tarifs also for commercial and private customers

Early bird markets for RESS

TUumlV SUumlD AG Slide 30Corporate Presentation14-01-22

In the near future

bull Installations of REN still continue soarring Sooner or later there is an oversupply of electricity at

particular weather conditions while not all fossil powerplants can easily reduce or shut down

bull Countries aiming to become almost 100 supplied by REN soner or later enter a bdquocriticalldquo

transition phase where fast storage systems can guarantee power supply and stability of

frequency

bull If flexible electric power tarifs are getting bdquomainstreamldquo new business modell will pop up (Store

when cheap sell when expensive)

bull Storage systems can even make money without selling in a bdquocapacity marketldquo

Image ABB

Coming markets for RESS

TUumlV SUumlD AG Slide 31Corporate Presentation14-01-22

In the future

bull With increasing amounts of REN in the grid grid stabilization frequency stabilization becomes a

necessity

bull Seasonal storage solutions ndash together with P2G technologies ndash might become necessary in

regions with an unbalanced build up of REN (a lot of PV no wind or a lot of wind but no PV)

bull Regions without stabil external electric grid connection (eg Japan) might have additional needs

for energy storage solutions

Image Danish Wind Energy Association

Challenges of (residential) storage systems

bull Economic success depends on lifetime performance ndash 10 years plus

bull Local environmental conditions must be specified and testet ndash insideoutside operation

bull Sytems installed in the house have more stabil conditions

but saftety requirements and proof of product safety is key

to insurance companies ndash fire insurance

bull There are almost no existing safety regulations for inhouse installations of RESS

bull Serveral countries (eg Japan Germany) issued guidelines for RESS

bull Standards are evolving ndash dynamic environment

bull US standards are slightly ahead ndash eg UL 1973 ndash but various additional approvals are necessary

(eg NFPA 70 ANSIZ 535)

bull Third party test labs have set up various certification schemes eg TUV SUD Mark for RESS

Legal requirements

The legal requirements

are defined by the legislation eg European Commission or US authorities and

regionallocal requirements like from ldquoFire Safety Authoritesrdquo

belongs to products produced in or imported to the markets

are addressing system safety health and environmental protection

Storage systems must comply in the European Union with the CE marking regulations and

related directives in North America with the listing requirements and the national codes

With the CE-mark or listing mark the manufacturer his authorized representative or the

importer indicate that the product meets the legal requirements

Helpful for the manufacturers are the harmonized product standards Following this

standards compliance is presumed (eg IEC 63056)

For the USA a product standard is available (UL 9540) but further requirements need to be

met

Good news amp even better news for REES

In a stable grid environment no REES are needed below

60-70 REN in the grid (at least below 50)

However there are further business models for REES

bull Reduced FIT lead to big price gap between FIT and utility electricity prices

(buy expensive but sell cheap In Germany 28 Cent vs 11 Cent FIT vs 5-6 Cent production)

bull Back-up power systems can bdquoearn moneyldquo in stead of just beeing bdquoreadyldquo

(Battery back-up systems are quicker no pollution no noise)

bull Not all regions in the world have a stable grid

bull High Power EV Charging (150-350 kW) needs bdquobufferldquo solutions

bull Regions with flexible tarifs are already today

TUumlV SUumlD 06022018 28

Early bird markets for RESS

TUumlV SUumlD AG Slide 29Corporate Presentation14-01-22

At the moment

bull Markets are mainly driven by subsidies Eg Germany 1000 Systems installed in 201617

(40 subsidies)

bull Solar (and EV) enthusiasts who just like the idea of storing their PV harvest and use it at night or

charge it into their EV over night

bull Grid operators and utilities are testing the systems despite theylsquore not really needed as of today

bull Some regions have really bdquoweakldquo grid conditions (partly eg Italy)

bull Some regions already have flexible tarifs also for commercial and private customers

Early bird markets for RESS

TUumlV SUumlD AG Slide 30Corporate Presentation14-01-22

In the near future

bull Installations of REN still continue soarring Sooner or later there is an oversupply of electricity at

particular weather conditions while not all fossil powerplants can easily reduce or shut down

bull Countries aiming to become almost 100 supplied by REN soner or later enter a bdquocriticalldquo

transition phase where fast storage systems can guarantee power supply and stability of

frequency

bull If flexible electric power tarifs are getting bdquomainstreamldquo new business modell will pop up (Store

when cheap sell when expensive)

bull Storage systems can even make money without selling in a bdquocapacity marketldquo

Image ABB

Coming markets for RESS

TUumlV SUumlD AG Slide 31Corporate Presentation14-01-22

In the future

bull With increasing amounts of REN in the grid grid stabilization frequency stabilization becomes a

necessity

bull Seasonal storage solutions ndash together with P2G technologies ndash might become necessary in

regions with an unbalanced build up of REN (a lot of PV no wind or a lot of wind but no PV)

bull Regions without stabil external electric grid connection (eg Japan) might have additional needs

for energy storage solutions

Image Danish Wind Energy Association

Challenges of (residential) storage systems

bull Economic success depends on lifetime performance ndash 10 years plus

bull Local environmental conditions must be specified and testet ndash insideoutside operation

bull Sytems installed in the house have more stabil conditions

but saftety requirements and proof of product safety is key

to insurance companies ndash fire insurance

bull There are almost no existing safety regulations for inhouse installations of RESS

bull Serveral countries (eg Japan Germany) issued guidelines for RESS

bull Standards are evolving ndash dynamic environment

bull US standards are slightly ahead ndash eg UL 1973 ndash but various additional approvals are necessary

(eg NFPA 70 ANSIZ 535)

bull Third party test labs have set up various certification schemes eg TUV SUD Mark for RESS

Legal requirements

The legal requirements

are defined by the legislation eg European Commission or US authorities and

regionallocal requirements like from ldquoFire Safety Authoritesrdquo

belongs to products produced in or imported to the markets

are addressing system safety health and environmental protection

Storage systems must comply in the European Union with the CE marking regulations and

related directives in North America with the listing requirements and the national codes

With the CE-mark or listing mark the manufacturer his authorized representative or the

importer indicate that the product meets the legal requirements

Helpful for the manufacturers are the harmonized product standards Following this

standards compliance is presumed (eg IEC 63056)

For the USA a product standard is available (UL 9540) but further requirements need to be

met

Good news amp even better news for REES

In a stable grid environment no REES are needed below

60-70 REN in the grid (at least below 50)

However there are further business models for REES

bull Reduced FIT lead to big price gap between FIT and utility electricity prices

(buy expensive but sell cheap In Germany 28 Cent vs 11 Cent FIT vs 5-6 Cent production)

bull Back-up power systems can bdquoearn moneyldquo in stead of just beeing bdquoreadyldquo

(Battery back-up systems are quicker no pollution no noise)

bull Not all regions in the world have a stable grid

bull High Power EV Charging (150-350 kW) needs bdquobufferldquo solutions

bull Regions with flexible tarifs are already today

bull Markets are mainly driven by subsidies Eg Germany 1000 Systems installed in 201617

(40 subsidies)

bull Solar (and EV) enthusiasts who just like the idea of storing their PV harvest and use it at night or

charge it into their EV over night

bull Grid operators and utilities are testing the systems despite theylsquore not really needed as of today

bull Some regions have really bdquoweakldquo grid conditions (partly eg Italy)

Early bird markets for RESS

TUumlV SUumlD AG Slide 30Corporate Presentation14-01-22

In the near future

bull Installations of REN still continue soarring Sooner or later there is an oversupply of electricity at

particular weather conditions while not all fossil powerplants can easily reduce or shut down

bull Countries aiming to become almost 100 supplied by REN soner or later enter a bdquocriticalldquo

transition phase where fast storage systems can guarantee power supply and stability of

frequency

bull If flexible electric power tarifs are getting bdquomainstreamldquo new business modell will pop up (Store

when cheap sell when expensive)

bull Storage systems can even make money without selling in a bdquocapacity marketldquo

Image ABB

Coming markets for RESS

TUumlV SUumlD AG Slide 31Corporate Presentation14-01-22

In the future

bull With increasing amounts of REN in the grid grid stabilization frequency stabilization becomes a

necessity

bull Seasonal storage solutions ndash together with P2G technologies ndash might become necessary in

regions with an unbalanced build up of REN (a lot of PV no wind or a lot of wind but no PV)

bull Regions without stabil external electric grid connection (eg Japan) might have additional needs

for energy storage solutions

Image Danish Wind Energy Association

Challenges of (residential) storage systems

bull Economic success depends on lifetime performance ndash 10 years plus

bull Local environmental conditions must be specified and testet ndash insideoutside operation

bull Sytems installed in the house have more stabil conditions

but saftety requirements and proof of product safety is key

to insurance companies ndash fire insurance

bull There are almost no existing safety regulations for inhouse installations of RESS

bull Serveral countries (eg Japan Germany) issued guidelines for RESS

bull Standards are evolving ndash dynamic environment

bull US standards are slightly ahead ndash eg UL 1973 ndash but various additional approvals are necessary

(eg NFPA 70 ANSIZ 535)

bull Third party test labs have set up various certification schemes eg TUV SUD Mark for RESS

Legal requirements

The legal requirements

are defined by the legislation eg European Commission or US authorities and

regionallocal requirements like from ldquoFire Safety Authoritesrdquo

belongs to products produced in or imported to the markets

are addressing system safety health and environmental protection

Storage systems must comply in the European Union with the CE marking regulations and

related directives in North America with the listing requirements and the national codes

With the CE-mark or listing mark the manufacturer his authorized representative or the

importer indicate that the product meets the legal requirements

Helpful for the manufacturers are the harmonized product standards Following this

standards compliance is presumed (eg IEC 63056)

For the USA a product standard is available (UL 9540) but further requirements need to be

met

Good news amp even better news for REES

In a stable grid environment no REES are needed below

60-70 REN in the grid (at least below 50)

However there are further business models for REES

bull Reduced FIT lead to big price gap between FIT and utility electricity prices

(buy expensive but sell cheap In Germany 28 Cent vs 11 Cent FIT vs 5-6 Cent production)

bull Back-up power systems can bdquoearn moneyldquo in stead of just beeing bdquoreadyldquo

(Battery back-up systems are quicker no pollution no noise)

bull Not all regions in the world have a stable grid

bull High Power EV Charging (150-350 kW) needs bdquobufferldquo solutions

bull Regions with flexible tarifs are already today

TUumlV SUumlD 06022018 28

Early bird markets for RESS

TUumlV SUumlD AG Slide 29Corporate Presentation14-01-22

At the moment

bull Markets are mainly driven by subsidies Eg Germany 1000 Systems installed in 201617

(40 subsidies)

bull Solar (and EV) enthusiasts who just like the idea of storing their PV harvest and use it at night or

charge it into their EV over night

bull Grid operators and utilities are testing the systems despite theylsquore not really needed as of today

bull Some regions have really bdquoweakldquo grid conditions (partly eg Italy)

bull Some regions already have flexible tarifs also for commercial and private customers

Early bird markets for RESS

TUumlV SUumlD AG Slide 30Corporate Presentation14-01-22

In the near future

bull Installations of REN still continue soarring Sooner or later there is an oversupply of electricity at

particular weather conditions while not all fossil powerplants can easily reduce or shut down

bull Countries aiming to become almost 100 supplied by REN soner or later enter a bdquocriticalldquo

transition phase where fast storage systems can guarantee power supply and stability of

frequency

bull If flexible electric power tarifs are getting bdquomainstreamldquo new business modell will pop up (Store

when cheap sell when expensive)

bull Storage systems can even make money without selling in a bdquocapacity marketldquo

Image ABB

Coming markets for RESS

TUumlV SUumlD AG Slide 31Corporate Presentation14-01-22

In the future

bull With increasing amounts of REN in the grid grid stabilization frequency stabilization becomes a

necessity

bull Seasonal storage solutions ndash together with P2G technologies ndash might become necessary in

regions with an unbalanced build up of REN (a lot of PV no wind or a lot of wind but no PV)

bull Regions without stabil external electric grid connection (eg Japan) might have additional needs

for energy storage solutions

Image Danish Wind Energy Association

Challenges of (residential) storage systems

bull Economic success depends on lifetime performance ndash 10 years plus

bull Local environmental conditions must be specified and testet ndash insideoutside operation

bull Sytems installed in the house have more stabil conditions

but saftety requirements and proof of product safety is key

to insurance companies ndash fire insurance

bull There are almost no existing safety regulations for inhouse installations of RESS

bull Serveral countries (eg Japan Germany) issued guidelines for RESS

bull Standards are evolving ndash dynamic environment

bull US standards are slightly ahead ndash eg UL 1973 ndash but various additional approvals are necessary

(eg NFPA 70 ANSIZ 535)

bull Third party test labs have set up various certification schemes eg TUV SUD Mark for RESS

Legal requirements

The legal requirements

are defined by the legislation eg European Commission or US authorities and

regionallocal requirements like from ldquoFire Safety Authoritesrdquo

belongs to products produced in or imported to the markets

are addressing system safety health and environmental protection

Storage systems must comply in the European Union with the CE marking regulations and

related directives in North America with the listing requirements and the national codes

With the CE-mark or listing mark the manufacturer his authorized representative or the

importer indicate that the product meets the legal requirements

Helpful for the manufacturers are the harmonized product standards Following this

standards compliance is presumed (eg IEC 63056)

For the USA a product standard is available (UL 9540) but further requirements need to be

met

Good news amp even better news for REES

In a stable grid environment no REES are needed below

60-70 REN in the grid (at least below 50)

However there are further business models for REES

bull Reduced FIT lead to big price gap between FIT and utility electricity prices

(buy expensive but sell cheap In Germany 28 Cent vs 11 Cent FIT vs 5-6 Cent production)

bull Back-up power systems can bdquoearn moneyldquo in stead of just beeing bdquoreadyldquo

(Battery back-up systems are quicker no pollution no noise)

bull Not all regions in the world have a stable grid

bull High Power EV Charging (150-350 kW) needs bdquobufferldquo solutions

bull Regions with flexible tarifs are already today

TUumlV SUumlD 06022018 28

Early bird markets for RESS

TUumlV SUumlD AG Slide 29Corporate Presentation14-01-22

At the moment

bull Markets are mainly driven by subsidies Eg Germany 1000 Systems installed in 201617

(40 subsidies)

bull Solar (and EV) enthusiasts who just like the idea of storing their PV harvest and use it at night or

charge it into their EV over night

bull Grid operators and utilities are testing the systems despite theylsquore not really needed as of today

bull Some regions have really bdquoweakldquo grid conditions (partly eg Italy)

bull Some regions already have flexible tarifs also for commercial and private customers

Early bird markets for RESS

TUumlV SUumlD AG Slide 30Corporate Presentation14-01-22

In the near future

bull Installations of REN still continue soarring Sooner or later there is an oversupply of electricity at

particular weather conditions while not all fossil powerplants can easily reduce or shut down

bull Countries aiming to become almost 100 supplied by REN soner or later enter a bdquocriticalldquo

transition phase where fast storage systems can guarantee power supply and stability of

frequency

bull If flexible electric power tarifs are getting bdquomainstreamldquo new business modell will pop up (Store

when cheap sell when expensive)

bull Storage systems can even make money without selling in a bdquocapacity marketldquo

Image ABB

Coming markets for RESS

TUumlV SUumlD AG Slide 31Corporate Presentation14-01-22

In the future

bull With increasing amounts of REN in the grid grid stabilization frequency stabilization becomes a

necessity

bull Seasonal storage solutions ndash together with P2G technologies ndash might become necessary in

regions with an unbalanced build up of REN (a lot of PV no wind or a lot of wind but no PV)

bull Regions without stabil external electric grid connection (eg Japan) might have additional needs

for energy storage solutions

Image Danish Wind Energy Association

Challenges of (residential) storage systems

bull Economic success depends on lifetime performance ndash 10 years plus

bull Local environmental conditions must be specified and testet ndash insideoutside operation

bull Sytems installed in the house have more stabil conditions

but saftety requirements and proof of product safety is key

to insurance companies ndash fire insurance

bull There are almost no existing safety regulations for inhouse installations of RESS

bull Serveral countries (eg Japan Germany) issued guidelines for RESS

bull Standards are evolving ndash dynamic environment

bull US standards are slightly ahead ndash eg UL 1973 ndash but various additional approvals are necessary

(eg NFPA 70 ANSIZ 535)

bull Third party test labs have set up various certification schemes eg TUV SUD Mark for RESS

Legal requirements

The legal requirements

are defined by the legislation eg European Commission or US authorities and

regionallocal requirements like from ldquoFire Safety Authoritesrdquo

belongs to products produced in or imported to the markets

are addressing system safety health and environmental protection

Storage systems must comply in the European Union with the CE marking regulations and

related directives in North America with the listing requirements and the national codes

With the CE-mark or listing mark the manufacturer his authorized representative or the

importer indicate that the product meets the legal requirements

Helpful for the manufacturers are the harmonized product standards Following this

standards compliance is presumed (eg IEC 63056)

For the USA a product standard is available (UL 9540) but further requirements need to be

met

Good news amp even better news for REES

In a stable grid environment no REES are needed below

60-70 REN in the grid (at least below 50)

However there are further business models for REES

bull Reduced FIT lead to big price gap between FIT and utility electricity prices

(buy expensive but sell cheap In Germany 28 Cent vs 11 Cent FIT vs 5-6 Cent production)

bull Back-up power systems can bdquoearn moneyldquo in stead of just beeing bdquoreadyldquo

(Battery back-up systems are quicker no pollution no noise)

bull Not all regions in the world have a stable grid

bull High Power EV Charging (150-350 kW) needs bdquobufferldquo solutions

bull Regions with flexible tarifs are already today

TUumlV SUumlD 06022018 28

Early bird markets for RESS

TUumlV SUumlD AG Slide 29Corporate Presentation14-01-22

At the moment

bull Markets are mainly driven by subsidies Eg Germany 1000 Systems installed in 201617

(40 subsidies)

bull Solar (and EV) enthusiasts who just like the idea of storing their PV harvest and use it at night or

charge it into their EV over night

bull Grid operators and utilities are testing the systems despite theylsquore not really needed as of today

bull Some regions have really bdquoweakldquo grid conditions (partly eg Italy)

bull Some regions already have flexible tarifs also for commercial and private customers

Early bird markets for RESS

TUumlV SUumlD AG Slide 30Corporate Presentation14-01-22

In the near future

bull Installations of REN still continue soarring Sooner or later there is an oversupply of electricity at

particular weather conditions while not all fossil powerplants can easily reduce or shut down

bull Countries aiming to become almost 100 supplied by REN soner or later enter a bdquocriticalldquo

transition phase where fast storage systems can guarantee power supply and stability of

frequency

bull If flexible electric power tarifs are getting bdquomainstreamldquo new business modell will pop up (Store

when cheap sell when expensive)

bull Storage systems can even make money without selling in a bdquocapacity marketldquo

Image ABB

Coming markets for RESS

TUumlV SUumlD AG Slide 31Corporate Presentation14-01-22

In the future

bull With increasing amounts of REN in the grid grid stabilization frequency stabilization becomes a

necessity

bull Seasonal storage solutions ndash together with P2G technologies ndash might become necessary in

regions with an unbalanced build up of REN (a lot of PV no wind or a lot of wind but no PV)

bull Regions without stabil external electric grid connection (eg Japan) might have additional needs

for energy storage solutions

Image Danish Wind Energy Association

Challenges of (residential) storage systems

bull Economic success depends on lifetime performance ndash 10 years plus

bull Local environmental conditions must be specified and testet ndash insideoutside operation

bull Sytems installed in the house have more stabil conditions

but saftety requirements and proof of product safety is key

to insurance companies ndash fire insurance

bull There are almost no existing safety regulations for inhouse installations of RESS

bull Serveral countries (eg Japan Germany) issued guidelines for RESS

bull Standards are evolving ndash dynamic environment

bull US standards are slightly ahead ndash eg UL 1973 ndash but various additional approvals are necessary

(eg NFPA 70 ANSIZ 535)

bull Third party test labs have set up various certification schemes eg TUV SUD Mark for RESS

Legal requirements

The legal requirements

are defined by the legislation eg European Commission or US authorities and

regionallocal requirements like from ldquoFire Safety Authoritesrdquo

belongs to products produced in or imported to the markets

are addressing system safety health and environmental protection

Storage systems must comply in the European Union with the CE marking regulations and

related directives in North America with the listing requirements and the national codes

With the CE-mark or listing mark the manufacturer his authorized representative or the

importer indicate that the product meets the legal requirements

Helpful for the manufacturers are the harmonized product standards Following this

standards compliance is presumed (eg IEC 63056)

For the USA a product standard is available (UL 9540) but further requirements need to be

met

Good news amp even better news for REES

In a stable grid environment no REES are needed below

60-70 REN in the grid (at least below 50)

However there are further business models for REES

bull Reduced FIT lead to big price gap between FIT and utility electricity prices

(buy expensive but sell cheap In Germany 28 Cent vs 11 Cent FIT vs 5-6 Cent production)

bull Back-up power systems can bdquoearn moneyldquo in stead of just beeing bdquoreadyldquo

(Battery back-up systems are quicker no pollution no noise)

bull Not all regions in the world have a stable grid

bull High Power EV Charging (150-350 kW) needs bdquobufferldquo solutions

bull Regions with flexible tarifs are already today

TUumlV SUumlD 06022018 28

Early bird markets for RESS

TUumlV SUumlD AG Slide 29Corporate Presentation14-01-22

At the moment

bull Markets are mainly driven by subsidies Eg Germany 1000 Systems installed in 201617

(40 subsidies)

bull Solar (and EV) enthusiasts who just like the idea of storing their PV harvest and use it at night or

charge it into their EV over night

bull Grid operators and utilities are testing the systems despite theylsquore not really needed as of today

bull Some regions have really bdquoweakldquo grid conditions (partly eg Italy)

bull Some regions already have flexible tarifs also for commercial and private customers

Early bird markets for RESS

TUumlV SUumlD AG Slide 30Corporate Presentation14-01-22

In the near future

bull Installations of REN still continue soarring Sooner or later there is an oversupply of electricity at

particular weather conditions while not all fossil powerplants can easily reduce or shut down

bull Countries aiming to become almost 100 supplied by REN soner or later enter a bdquocriticalldquo

transition phase where fast storage systems can guarantee power supply and stability of

frequency

bull If flexible electric power tarifs are getting bdquomainstreamldquo new business modell will pop up (Store

when cheap sell when expensive)

bull Storage systems can even make money without selling in a bdquocapacity marketldquo

Image ABB

Coming markets for RESS

TUumlV SUumlD AG Slide 31Corporate Presentation14-01-22

In the future

bull With increasing amounts of REN in the grid grid stabilization frequency stabilization becomes a

necessity

bull Seasonal storage solutions ndash together with P2G technologies ndash might become necessary in

regions with an unbalanced build up of REN (a lot of PV no wind or a lot of wind but no PV)

bull Regions without stabil external electric grid connection (eg Japan) might have additional needs

for energy storage solutions

Image Danish Wind Energy Association

Challenges of (residential) storage systems

bull Economic success depends on lifetime performance ndash 10 years plus

bull Local environmental conditions must be specified and testet ndash insideoutside operation

bull Sytems installed in the house have more stabil conditions

but saftety requirements and proof of product safety is key

to insurance companies ndash fire insurance

bull There are almost no existing safety regulations for inhouse installations of RESS

bull Serveral countries (eg Japan Germany) issued guidelines for RESS

bull Standards are evolving ndash dynamic environment

bull US standards are slightly ahead ndash eg UL 1973 ndash but various additional approvals are necessary

(eg NFPA 70 ANSIZ 535)

bull Third party test labs have set up various certification schemes eg TUV SUD Mark for RESS

Legal requirements

The legal requirements

are defined by the legislation eg European Commission or US authorities and

regionallocal requirements like from ldquoFire Safety Authoritesrdquo

belongs to products produced in or imported to the markets

are addressing system safety health and environmental protection

Storage systems must comply in the European Union with the CE marking regulations and

related directives in North America with the listing requirements and the national codes

With the CE-mark or listing mark the manufacturer his authorized representative or the

importer indicate that the product meets the legal requirements

Helpful for the manufacturers are the harmonized product standards Following this

standards compliance is presumed (eg IEC 63056)

For the USA a product standard is available (UL 9540) but further requirements need to be

met

Good news amp even better news for REES

In a stable grid environment no REES are needed below

60-70 REN in the grid (at least below 50)

However there are further business models for REES

bull Reduced FIT lead to big price gap between FIT and utility electricity prices

(buy expensive but sell cheap In Germany 28 Cent vs 11 Cent FIT vs 5-6 Cent production)

bull Back-up power systems can bdquoearn moneyldquo in stead of just beeing bdquoreadyldquo

(Battery back-up systems are quicker no pollution no noise)

bull Not all regions in the world have a stable grid

bull High Power EV Charging (150-350 kW) needs bdquobufferldquo solutions

bull Regions with flexible tarifs are already today

TUumlV SUumlD 06022018 28

Early bird markets for RESS

TUumlV SUumlD AG Slide 29Corporate Presentation14-01-22

At the moment

bull Markets are mainly driven by subsidies Eg Germany 1000 Systems installed in 201617

(40 subsidies)

bull Solar (and EV) enthusiasts who just like the idea of storing their PV harvest and use it at night or

charge it into their EV over night

bull Grid operators and utilities are testing the systems despite theylsquore not really needed as of today

bull Some regions have really bdquoweakldquo grid conditions (partly eg Italy)

bull Some regions already have flexible tarifs also for commercial and private customers

Early bird markets for RESS

TUumlV SUumlD AG Slide 30Corporate Presentation14-01-22

In the near future

bull Installations of REN still continue soarring Sooner or later there is an oversupply of electricity at

particular weather conditions while not all fossil powerplants can easily reduce or shut down

bull Countries aiming to become almost 100 supplied by REN soner or later enter a bdquocriticalldquo

transition phase where fast storage systems can guarantee power supply and stability of

frequency

bull If flexible electric power tarifs are getting bdquomainstreamldquo new business modell will pop up (Store

when cheap sell when expensive)

bull Storage systems can even make money without selling in a bdquocapacity marketldquo

Image ABB

Coming markets for RESS

TUumlV SUumlD AG Slide 31Corporate Presentation14-01-22

In the future

bull With increasing amounts of REN in the grid grid stabilization frequency stabilization becomes a

necessity

bull Seasonal storage solutions ndash together with P2G technologies ndash might become necessary in

regions with an unbalanced build up of REN (a lot of PV no wind or a lot of wind but no PV)

bull Regions without stabil external electric grid connection (eg Japan) might have additional needs

for energy storage solutions

Image Danish Wind Energy Association

Challenges of (residential) storage systems

bull Economic success depends on lifetime performance ndash 10 years plus

bull Local environmental conditions must be specified and testet ndash insideoutside operation

bull Sytems installed in the house have more stabil conditions

but saftety requirements and proof of product safety is key

to insurance companies ndash fire insurance

bull There are almost no existing safety regulations for inhouse installations of RESS

bull Serveral countries (eg Japan Germany) issued guidelines for RESS

bull Standards are evolving ndash dynamic environment

bull US standards are slightly ahead ndash eg UL 1973 ndash but various additional approvals are necessary

(eg NFPA 70 ANSIZ 535)

bull Third party test labs have set up various certification schemes eg TUV SUD Mark for RESS

Legal requirements

The legal requirements

are defined by the legislation eg European Commission or US authorities and

regionallocal requirements like from ldquoFire Safety Authoritesrdquo

belongs to products produced in or imported to the markets

are addressing system safety health and environmental protection

Storage systems must comply in the European Union with the CE marking regulations and

related directives in North America with the listing requirements and the national codes

With the CE-mark or listing mark the manufacturer his authorized representative or the

importer indicate that the product meets the legal requirements

Helpful for the manufacturers are the harmonized product standards Following this

standards compliance is presumed (eg IEC 63056)

For the USA a product standard is available (UL 9540) but further requirements need to be

met

TUumlV SUumlD 06022018 37

Global market access recommended strategy

TUumlV SUumlD AG Slide 38Corporate Presentation14-01-22

Basic steps of the strategy are

Step 1 Find the applicable directives standards and regulations

Step 2 Determine the applicable conformity assessment module

Step 3 Carry out a risk assessment define measures based on harmonized standards

(FMEA SIL FUSIhellip)

Step 4 Implement the measures defined at the risk assessment

Step 5 Create the technical file (TF)

Step 6 Declare conformity and do the CE-marking apply for UL 9540 compliance

(buy expensive but sell cheap In Germany 28 Cent vs 11 Cent FIT vs 5-6 Cent production)

bull Back-up power systems can bdquoearn moneyldquo in stead of just beeing bdquoreadyldquo

(Battery back-up systems are quicker no pollution no noise)

bull Not all regions in the world have a stable grid

bull High Power EV Charging (150-350 kW) needs bdquobufferldquo solutions

bull Regions with flexible tarifs are already today

Early bird markets for RESS

TUumlV SUumlD AG Slide 29Corporate Presentation14-01-22

At the moment

bull Markets are mainly driven by subsidies Eg Germany 1000 Systems installed in 201617

(40 subsidies)

bull Solar (and EV) enthusiasts who just like the idea of storing their PV harvest and use it at night or

charge it into their EV over night

bull Grid operators and utilities are testing the systems despite theylsquore not really needed as of today

bull Some regions have really bdquoweakldquo grid conditions (partly eg Italy)

bull Some regions already have flexible tarifs also for commercial and private customers

In the near future

bull Installations of REN still continue soarring Sooner or later there is an oversupply of electricity at

particular weather conditions while not all fossil powerplants can easily reduce or shut down

bull Countries aiming to become almost 100 supplied by REN soner or later enter a bdquocriticalldquo

transition phase where fast storage systems can guarantee power supply and stability of

frequency

bull If flexible electric power tarifs are getting bdquomainstreamldquo new business modell will pop up (Store

when cheap sell when expensive)

bull Storage systems can even make money without selling in a bdquocapacity marketldquo

Coming markets for RESS

TUumlV SUumlD AG Slide 31Corporate Presentation14-01-22

In the future

bull With increasing amounts of REN in the grid grid stabilization frequency stabilization becomes a

necessity

bull Seasonal storage solutions ndash together with P2G technologies ndash might become necessary in

regions with an unbalanced build up of REN (a lot of PV no wind or a lot of wind but no PV)

bull Regions without stabil external electric grid connection (eg Japan) might have additional needs

for energy storage solutions

Challenges of (residential) storage systems

bull Economic success depends on lifetime performance ndash 10 years plus

bull Local environmental conditions must be specified and testet ndash insideoutside operation

bull Sytems installed in the house have more stabil conditions

but saftety requirements and proof of product safety is key

to insurance companies ndash fire insurance

bull There are almost no existing safety regulations for inhouse installations of RESS

bull Serveral countries (eg Japan Germany) issued guidelines for RESS

bull Standards are evolving ndash dynamic environment

bull US standards are slightly ahead ndash eg UL 1973 ndash but various additional approvals are necessary

(eg NFPA 70 ANSIZ 535)

bull Third party test labs have set up various certification schemes eg TUV SUD Mark for RESS

Good news amp even better news for REES

In a stable grid environment no REES are needed below

60-70 REN in the grid (at least below 50)

However there are further business models for REES

bull Reduced FIT lead to big price gap between FIT and utility electricity prices

(buy expensive but sell cheap In Germany 28 Cent vs 11 Cent FIT vs 5-6 Cent production)

bull Back-up power systems can bdquoearn moneyldquo in stead of just beeing bdquoreadyldquo

(Battery back-up systems are quicker no pollution no noise)

bull Not all regions in the world have a stable grid

bull High Power EV Charging (150-350 kW) needs bdquobufferldquo solutions

bull Regions with flexible tarifs are already today

TUumlV SUumlD AG Slide 29Corporate Presentation14-01-22

At the moment

bull Markets are mainly driven by subsidies Eg Germany 1000 Systems installed in 201617

(40 subsidies)

bull Solar (and EV) enthusiasts who just like the idea of storing their PV harvest and use it at night or

charge it into their EV over night

bull Grid operators and utilities are testing the systems despite theylsquore not really needed as of today

bull Some regions have really bdquoweakldquo grid conditions (partly eg Italy)

In the near future

bull Installations of REN still continue soarring Sooner or later there is an oversupply of electricity at

particular weather conditions while not all fossil powerplants can easily reduce or shut down

bull Countries aiming to become almost 100 supplied by REN soner or later enter a bdquocriticalldquo

transition phase where fast storage systems can guarantee power supply and stability of

frequency

bull If flexible electric power tarifs are getting bdquomainstreamldquo new business modell will pop up (Store

when cheap sell when expensive)

bull Storage systems can even make money without selling in a bdquocapacity marketldquo

TUumlV SUumlD AG Slide 31Corporate Presentation14-01-22

In the future

bull With increasing amounts of REN in the grid grid stabilization frequency stabilization becomes a

necessity

bull Seasonal storage solutions ndash together with P2G technologies ndash might become necessary in

regions with an unbalanced build up of REN (a lot of PV no wind or a lot of wind but no PV)

bull Regions without stabil external electric grid connection (eg Japan) might have additional needs

for energy storage solutions

Image Danish Wind Energy Association

Challenges of (residential) storage systems

bull Economic success depends on lifetime performance ndash 10 years plus

bull Local environmental conditions must be specified and testet ndash insideoutside operation

bull Sytems installed in the house have more stabil conditions

but saftety requirements and proof of product safety is key

to insurance companies ndash fire insurance

bull There are almost no existing safety regulations for inhouse installations of RESS

bull Serveral countries (eg Japan Germany) issued guidelines for RESS

bull Standards are evolving ndash dynamic environment

bull US standards are slightly ahead ndash eg UL 1973 ndash but various additional approvals are necessary

(eg NFPA 70 ANSIZ 535)

Legal requirements

The legal requirements

are defined by the legislation eg European Commission or US authorities and

regionallocal requirements like from ldquoFire Safety Authoritesrdquo

belongs to products produced in or imported to the markets

are addressing system safety health and environmental protection

Storage systems must comply in the European Union with the CE marking regulations and

related directives in North America with the listing requirements and the national codes

With the CE-mark or listing mark the manufacturer his authorized representative or the

importer indicate that the product meets the legal requirements

Helpful for the manufacturers are the harmonized product standards Following this

standards compliance is presumed (eg IEC 63056)

For the USA a product standard is available (UL 9540) but further requirements need to be

met

TUumlV SUumlD 06022018 37

Basic steps of the strategy are

Step 1 Find the applicable directives standards and regulations

Step 2 Determine the applicable conformity assessment module

Step 3 Carry out a risk assessment define measures based on harmonized standards

(FMEA SIL FUSIhellip)

Step 4 Implement the measures defined at the risk assessment

Step 5 Create the technical file (TF)

Step 6 Declare conformity and do the CE-marking apply for UL 9540 compliance

Good news amp even better news for REES

In a stable grid environment no REES are needed below

60-70 REN in the grid (at least below 50)

However there are further business models for REES

bull Reduced FIT lead to big price gap between FIT and utility electricity prices

(buy expensive but sell cheap In Germany 28 Cent vs 11 Cent FIT vs 5-6 Cent production)

bull Back-up power systems can bdquoearn moneyldquo in stead of just beeing bdquoreadyldquo

(Battery back-up systems are quicker no pollution no noise)

bull Not all regions in the world have a stable grid

bull High Power EV Charging (150-350 kW) needs bdquobufferldquo solutions

bull Regions with flexible tarifs are already today

TUumlV SUumlD 06022018 28

Early bird markets for RESS

TUumlV SUumlD AG Slide 29Corporate Presentation14-01-22

At the moment

bull Markets are mainly driven by subsidies Eg Germany 1000 Systems installed in 201617

(40 subsidies)

bull Solar (and EV) enthusiasts who just like the idea of storing their PV harvest and use it at night or

charge it into their EV over night

bull Grid operators and utilities are testing the systems despite theylsquore not really needed as of today

bull Some regions have really bdquoweakldquo grid conditions (partly eg Italy)

bull Some regions already have flexible tarifs also for commercial and private customers

Early bird markets for RESS

TUumlV SUumlD AG Slide 30Corporate Presentation14-01-22

In the near future

bull Installations of REN still continue soarring Sooner or later there is an oversupply of electricity at

particular weather conditions while not all fossil powerplants can easily reduce or shut down

bull Countries aiming to become almost 100 supplied by REN soner or later enter a bdquocriticalldquo

transition phase where fast storage systems can guarantee power supply and stability of

frequency

bull If flexible electric power tarifs are getting bdquomainstreamldquo new business modell will pop up (Store

when cheap sell when expensive)

bull Storage systems can even make money without selling in a bdquocapacity marketldquo

Image ABB

Coming markets for RESS

TUumlV SUumlD AG Slide 31Corporate Presentation14-01-22

In the future

bull With increasing amounts of REN in the grid grid stabilization frequency stabilization becomes a

necessity

bull Seasonal storage solutions ndash together with P2G technologies ndash might become necessary in

regions with an unbalanced build up of REN (a lot of PV no wind or a lot of wind but no PV)

bull Regions without stabil external electric grid connection (eg Japan) might have additional needs

for energy storage solutions

Image Danish Wind Energy Association

Challenges of (residential) storage systems

bull Economic success depends on lifetime performance ndash 10 years plus

bull Local environmental conditions must be specified and testet ndash insideoutside operation

bull Sytems installed in the house have more stabil conditions

but saftety requirements and proof of product safety is key

to insurance companies ndash fire insurance

bull There are almost no existing safety regulations for inhouse installations of RESS

bull Serveral countries (eg Japan Germany) issued guidelines for RESS

bull Standards are evolving ndash dynamic environment

bull US standards are slightly ahead ndash eg UL 1973 ndash but various additional approvals are necessary

(eg NFPA 70 ANSIZ 535)

bull Third party test labs have set up various certification schemes eg TUV SUD Mark for RESS

Good news amp even better news for REES

In a stable grid environment no REES are needed below

60-70 REN in the grid (at least below 50)

However there are further business models for REES

bull Reduced FIT lead to big price gap between FIT and utility electricity prices

(buy expensive but sell cheap In Germany 28 Cent vs 11 Cent FIT vs 5-6 Cent production)

bull Back-up power systems can bdquoearn moneyldquo in stead of just beeing bdquoreadyldquo

(Battery back-up systems are quicker no pollution no noise)

bull Not all regions in the world have a stable grid

bull High Power EV Charging (150-350 kW) needs bdquobufferldquo solutions

bull Regions with flexible tarifs are already today

TUumlV SUumlD AG Slide 29Corporate Presentation14-01-22

At the moment

bull Markets are mainly driven by subsidies Eg Germany 1000 Systems installed in 201617

(40 subsidies)

bull Solar (and EV) enthusiasts who just like the idea of storing their PV harvest and use it at night or

charge it into their EV over night

bull Grid operators and utilities are testing the systems despite theylsquore not really needed as of today

bull Some regions have really bdquoweakldquo grid conditions (partly eg Italy)

bull Some regions already have flexible tarifs also for commercial and private customers

In the near future

bull Installations of REN still continue soarring Sooner or later there is an oversupply of electricity at

particular weather conditions while not all fossil powerplants can easily reduce or shut down

bull Countries aiming to become almost 100 supplied by REN soner or later enter a bdquocriticalldquo

transition phase where fast storage systems can guarantee power supply and stability of

frequency

bull If flexible electric power tarifs are getting bdquomainstreamldquo new business modell will pop up (Store

In the future

bull With increasing amounts of REN in the grid grid stabilization frequency stabilization becomes a

necessity

bull Seasonal storage solutions ndash together with P2G technologies ndash might become necessary in

regions with an unbalanced build up of REN (a lot of PV no wind or a lot of wind but no PV)

bull Regions without stabil external electric grid connection (eg Japan) might have additional needs

for energy storage solutions

Challenges of (residential) storage systems

bull Economic success depends on lifetime performance ndash 10 years plus

bull Local environmental conditions must be specified and testet ndash insideoutside operation

bull Sytems installed in the house have more stabil conditions

but saftety requirements and proof of product safety is key

to insurance companies ndash fire insurance

bull There are almost no existing safety regulations for inhouse installations of RESS

bull Serveral countries (eg Japan Germany) issued guidelines for RESS

bull Standards are evolving ndash dynamic environment

Good news amp even better news for REES

In a stable grid environment no REES are needed below

60-70 REN in the grid (at least below 50)

However there are further business models for REES

bull Reduced FIT lead to big price gap between FIT and utility electricity prices

(buy expensive but sell cheap In Germany 28 Cent vs 11 Cent FIT vs 5-6 Cent production)

bull Back-up power systems can bdquoearn moneyldquo in stead of just beeing bdquoreadyldquo

Challenges of (residential) storage systems

bull Economic success depends on lifetime performance ndash 10 years plus

bull Local environmental conditions must be specified and testet ndash insideoutside operation

bull Sytems installed in the house have more stabil conditions

but saftety requirements and proof of product safety is key

to insurance companies ndash fire insurance

bull There are almost no existing safety regulations for inhouse installations of RESS

bull Serveral countries (eg Japan Germany) issued guidelines for RESS

bull Standards are evolving ndash dynamic environment

bull US standards are slightly ahead ndash eg UL 1973 ndash but various additional approvals are necessary

(eg NFPA 70 ANSIZ 535)

bull Third party test labs have set up various certification schemes eg TUV SUD Mark for RESS

Legal requirements

The legal requirements

are defined by the legislation eg European Commission or US authorities and

regionallocal requirements like from ldquoFire Safety Authoritesrdquo

belongs to products produced in or imported to the markets

are addressing system safety health and environmental protection

Storage systems must comply in the European Union with the CE marking regulations and

related directives in North America with the listing requirements and the national codes

With the CE-mark or listing mark the manufacturer his authorized representative or the

importer indicate that the product meets the legal requirements

Helpful for the manufacturers are the harmonized product standards Following this

standards compliance is presumed (eg IEC 63056)

For the USA a product standard is available (UL 9540) but further requirements need to be

met
