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

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

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

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

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

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

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

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

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 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

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

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

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

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

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 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

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 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

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

(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

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
(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

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

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 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

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

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

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

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

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

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

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

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)

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 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

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

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

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

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

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

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
