Recap – Other Seminars
• At previous seminars we combined messages:
– prices have risen by ~5 per cent since 2000
– prices will continue to rise (and can be volatile)
– we can control the way we use electricity in order to manage cost
– we can also contract out of exposure to price volatility
Take Out: Controlling electricity consumption while contracting out of price volatility will become increasingly valuable to you
![Page 5: FMANZ gratefully acknowledges the support of our Gold Sponsors](https://reader036.vdocuments.us/reader036/viewer/2022081515/56814943550346895db68d39/html5/thumbnails/5.jpg)

This Time
• This time:
– what is going on in the electricity sector that might be of interest
– how may this impact you and decisions you make?

• However, there are some cross winds to be aware of:
– the global economy is weak
– NZ electric demand is weak
– reasonable levels of supply (absent hydro shortage)
Cross Winds
![Page 8: FMANZ gratefully acknowledges the support of our Gold Sponsors](https://reader036.vdocuments.us/reader036/viewer/2022081515/56814943550346895db68d39/html5/thumbnails/8.jpg)

• Since 2007, NZ electric demand has been reasonably static
• The drivers of flat demand are well documented
– low inflows in 2008 (where consumers were asked to conserve), the global financial crisis, NZAS transformer failure, the Christchurch earthquake and improved energy intensity by consumers

Cross Winds – NZ Electric Demand
• Looking forward, much of the above uncertainty continues to exist
– ongoing global economic instability and more local impacts are expected to remain
– NZAS & Norske Skog announcements are indicators of difficulty that is possibly widespread
• This graph includes ~2,000GWh of new supply being added over the next three years
Forecast demand growth
![Page 10: FMANZ gratefully acknowledges the support of our Gold Sponsors](https://reader036.vdocuments.us/reader036/viewer/2022081515/56814943550346895db68d39/html5/thumbnails/10.jpg)

• Offsetting all of the above is hydro fuel availability (inflow volatility)
• NZ electricity prices largely a function of hydro storage (unlike other countries)

• Some of our competitors will have big decisions to make
– Genesis has said it will shut two Huntly units – one in 2012 and one in 2014
– Contact is considering repowering its Otahuhu station
• And there are some very specific challenges to overcome
– Transpower is completing a number of large transmission upgrades in the near term
– Genesis is relining the Tekapo canal
– NZAS request to renegotiate contractual terms (approx 12% of NZ demand)

• My role is to manage these issues for Meridian
• More importantly, what do they mean for you?
![Page 15: FMANZ gratefully acknowledges the support of our Gold Sponsors](https://reader036.vdocuments.us/reader036/viewer/2022081515/56814943550346895db68d39/html5/thumbnails/15.jpg)
What Does it Mean for You?
• there are some cross currents for electricity prices– they are still likely to increase
• some of the specific risks in the near term may result in some volatility– the next 6 months include major transmission upgrade works
– contracts provide relief from volatility – both specific risk and hydrology
• contract duration should match your business risk profile
• continue hunting down waste regardless

Managing Electricity in Your Business
The Essentials

![Page 17: FMANZ gratefully acknowledges the support of our Gold Sponsors](https://reader036.vdocuments.us/reader036/viewer/2022081515/56814943550346895db68d39/html5/thumbnails/17.jpg)
First things first – Site Type?
• Two types of site in the electricity world
17
Small* Commercial/Residential sites e.g. your house, small-mid size retail
Large* Commercial / Industriale.g. manufacturing, hotels, supermarkets
Meters read periodically (frequency depends) Consumption recorded every half hour
“Anytime” is just one price Price varies (time of day + month)
Network charges may be ‘bundled’ into rate Network charges are separated
Non-Half Hourly Time of Use
* Threshold varies by Network

What charges are included in a bill?
There are two major cost components:
Energy (Wholesale purchase + Retailer)
Network (Network company e.g. Vector)
![Page 19: FMANZ gratefully acknowledges the support of our Gold Sponsors](https://reader036.vdocuments.us/reader036/viewer/2022081515/56814943550346895db68d39/html5/thumbnails/19.jpg)
19
• Variable Pricing– Energy component subject to change (30 days notice)– Network charges change when those companies change their rates– No price certainty. This is the default or ‘Do Nothing’ option
• Fixed Energy Plan– The Energy component of your rate is fixed – typically for 2-3 yrs– As above, Network charges change– Gives you significant (but not quite complete) price certainty
• Select a specific tariff for your needs– Options are determined by metering configuration– Metering changes can enable savings– Options differ by network– Examples include
• Day/Night/Weekend tariffs• ‘Controlled’ rates• Seasonality in some networks
Your Pricing Options – Non Half Hourly
Main Message: Talk to an expert
![Page 20: FMANZ gratefully acknowledges the support of our Gold Sponsors](https://reader036.vdocuments.us/reader036/viewer/2022081515/56814943550346895db68d39/html5/thumbnails/20.jpg)
20
• Fixed Price (with Variable Volume)– Meridian calls this “Easiplan” – it is the most common contract– Provides price certainty and insulates you from spot market fluctuations– Pricing is ‘shaped’ so that different rates apply at different times
• Spot Pricing– This is 100% exposure to the wholesale market (incl. Admin fee) – Expect significant variability in the price you pay each month
• Proportional Pricing– Mixture of Fixed Price and Spot – Select % you want fixed
e.g. 80% fixed price, 20% on spot market
• More complex options – Spot supply with Contracts for Differences (CFDs or Hedges)
Your Pricing Options – Time of Use
Main Message: Talk to an expert
![Page 21: FMANZ gratefully acknowledges the support of our Gold Sponsors](https://reader036.vdocuments.us/reader036/viewer/2022081515/56814943550346895db68d39/html5/thumbnails/21.jpg)

Two primary ways to manage your budget
1. Enter into a Supply Agreement– Define what you are looking for in a supplier and ask Retailers to respond– Use competition to get the best outcome for you– Choose a supplier that will add value (we of course think there is only one)
2. Take Control of your electricity consumption– Request data from your retailer or use their on-line tools (Business On Line)– Eliminate waste! Consider undertaking an energy audit– Take advantage of pricing
differentialse.g. night vs. day rates

Managing Your Electricity Budget
We are here to help
![Page 22: FMANZ gratefully acknowledges the support of our Gold Sponsors](https://reader036.vdocuments.us/reader036/viewer/2022081515/56814943550346895db68d39/html5/thumbnails/22.jpg)
22
– How much do you spend on electricity per annum and how material is it to you?
– What is your business’s appetite for price risk?
– How well do you understand the electricity market – do you need help?
– Do suppliers values align with yours?e.g. sustainability
– Are you aware of what Retailers offer beyond of price? (On Line, Electronic Invoicing, payment terms,reporting, account management)
– If you are considering participating in asupply group, are the group’s requirementsaligned with yours?
Supply Agreements: Key Questions for You
In the success game – Value always beats Price
![Page 23: FMANZ gratefully acknowledges the support of our Gold Sponsors](https://reader036.vdocuments.us/reader036/viewer/2022081515/56814943550346895db68d39/html5/thumbnails/23.jpg)
23
Take Outs
• controlling consumption will become increasingly valuable
• wholesale price volatility reflects the place we live
– this volatility is not a new feature
• if you enter into contracts, define what success looks like before you begin
– use trusted partners to get there and ask for advice on how to structure along the way
![Page 24: FMANZ gratefully acknowledges the support of our Gold Sponsors](https://reader036.vdocuments.us/reader036/viewer/2022081515/56814943550346895db68d39/html5/thumbnails/24.jpg)

Understand Your Site/Portfolio
How Much Energy do I use?
How much is it costing me?
![Page 29: FMANZ gratefully acknowledges the support of our Gold Sponsors](https://reader036.vdocuments.us/reader036/viewer/2022081515/56814943550346895db68d39/html5/thumbnails/29.jpg)
How does this site compare?What is a common unit of measure? kWh? FTE’s? Output?
What is the trend?
How does it compare to similar sites?
![Page 30: FMANZ gratefully acknowledges the support of our Gold Sponsors](https://reader036.vdocuments.us/reader036/viewer/2022081515/56814943550346895db68d39/html5/thumbnails/30.jpg)
How can I as an FM make energy savings?
Minimise the energy costs
Review the operational requirements of the current
tenant
Compare against your building plant operating hours
Invest in cost-effective improvements
Use life-cycle costing
Start a structured programme with regular reviews
![Page 31: FMANZ gratefully acknowledges the support of our Gold Sponsors](https://reader036.vdocuments.us/reader036/viewer/2022081515/56814943550346895db68d39/html5/thumbnails/31.jpg)
Reduce energy costs to your site(s)Energy Supply Cost
Key information How much has it cost me last year? and What will it cost me next year?
Tender for the supply of energygain best priceAlways avoid default rates.
Our experience: two out of three tenders lead to a change in supplier based usually on priceMyth of Security of Supply
![Page 32: FMANZ gratefully acknowledges the support of our Gold Sponsors](https://reader036.vdocuments.us/reader036/viewer/2022081515/56814943550346895db68d39/html5/thumbnails/32.jpg)
Network and line costs Network costs are NOT fixed and NOT only Daily chargeNetwork Optimisation:Review nominated capacity charges (HV)
Ensure that you are in the best network load group Check every couple of years!
Examples:Food: In Christchurch changed load group on 3 sites with annual savings over $160,000 p.a.School: Increase capacity & change load group, savings $10,000 p.a.
Power factor - penalty charges introduced by Vector 2012

Review site operating requirements and current control settings
Establish current building system operating requirementsWhat is plant controlling?
time clock, security system, BMS
What is the time on the controlling system? When is plant set to turn on and off?Review regularly as site operations change. Do not be surprised is time of the time clock or other controls are wrong! “Lazy running” - Daylight savings often see plant running an hour longer than required every day
![Page 36: FMANZ gratefully acknowledges the support of our Gold Sponsors](https://reader036.vdocuments.us/reader036/viewer/2022081515/56814943550346895db68d39/html5/thumbnails/36.jpg)

Saving Energy is about Reducing Waste
Actively manage control systems
Building walk through - outside normal operating
hours!
Identify controllable loads
Identify control options that are cost effective
Sensor; time switch; Use existing control system or
install new control systems?
![Page 42: FMANZ gratefully acknowledges the support of our Gold Sponsors](https://reader036.vdocuments.us/reader036/viewer/2022081515/56814943550346895db68d39/html5/thumbnails/42.jpg)
Use Life Cycle costing to establish benefit
Life cycle costing (LCC) looks at the maintained
life of a system over a period of time to provide a
more accurate view of the financial benefits of each
option. LCC factors in the:
•Purchase cost; and
•Energy cost; and
•Maintenance costs of the system.
There are very few energy related opportunities
that can be justified on energy reduction alone.

What is not working well in terms of Energy Management
A large number of sophisticated control systems are failing to deliver the benefits for the end users REASON: No-one is actively managing these systems.This is a LOSE-LOSE: High OPEX costs increases costs to tenants and reduces value of building.Unless these systems are managed in a continuous and proactive manner there is no financial benefit derived from having them installed.
A $100,000 BMS is (often) just an expensive time clock

SOLUTIONUse a third party to manage control systems!Removes risk of knowledge being lost when an employee moves on. These “management costs” should form part of the OPEX for the building and be passed through to Tenant(s) in all lease agreements. Financial Benefits will exceed Management costs, reducing OPEXCreates a WIN-WIN

Key areas to focus for low cost benefitsEnsure the technology you already have is actively managedUse metering information.
Saving 1 kW baseload saves more that 6,000 kWh pa ~ $900
Consider professional help - it will be cost effective!You need to measure to manage.Monitor and report operational savings (energy and other system savings). Use action plans and targets (with regular meetings).The old adage is true - a team works better than an individual

A meter is a meter is a meter, unless it’s a smart meter
• Records half-hourly consumption data.
• Regularly transmits consumption data.
• Remotely receives meter configuration data.
• What they are not…– A check meter– A control device
![Page 50: FMANZ gratefully acknowledges the support of our Gold Sponsors](https://reader036.vdocuments.us/reader036/viewer/2022081515/56814943550346895db68d39/html5/thumbnails/50.jpg)
The benefits of awareness
• Knowing what, how, and when, power is being used provides for the opportunity to make changes.– Performance monitoring

Smart meters enable the development of new pricing structures
• Measuring consumption in 30 min intervals allows for pricing at 30 min intervals.
• Electricity pricing in the New Zealand market follows supply and demand triggers, on a daily, weekly and yearly basis.

Access and deployment
• Smart meter deployment is continuing across NZ.• Access to data is becoming available to customers.• Retailers are developing systems that will
incorporate data from different meters providers.• Smart meters can be installed outside of roll-out
programmes… but may incur a cost.
![Page 55: FMANZ gratefully acknowledges the support of our Gold Sponsors](https://reader036.vdocuments.us/reader036/viewer/2022081515/56814943550346895db68d39/html5/thumbnails/55.jpg)
Smart meter takeaways
• Awareness and monitoring can save money
• Pricing plans that better fit industry consumption are coming
• Smart meters can be installed at customer request – if interested talk to one us.

![Page 57: FMANZ gratefully acknowledges the support of our Gold Sponsors](https://reader036.vdocuments.us/reader036/viewer/2022081515/56814943550346895db68d39/html5/thumbnails/57.jpg)
Why?
• To better understand electricity usage across multiple sites
• Identify opportunities to reduce emissions
• Lower consumption costs
• Provide real-time feedback on variances and potential issues
• Eliminate need for meter reading and bill estimates
![Page 58: FMANZ gratefully acknowledges the support of our Gold Sponsors](https://reader036.vdocuments.us/reader036/viewer/2022081515/56814943550346895db68d39/html5/thumbnails/58.jpg)
How?
• National deployment
• Data analysis and reporting
• Corrective actions
• Performance monitoring
![Page 59: FMANZ gratefully acknowledges the support of our Gold Sponsors](https://reader036.vdocuments.us/reader036/viewer/2022081515/56814943550346895db68d39/html5/thumbnails/59.jpg)

National Deployment - Site PreparationThe (simplified) installation process……
– Arc Innovation set up steps– Westpac engagement to allow for installation– Westpac to IT server management– Meter installation
Installation challenges– Contractor failure – IT hardware failure – Insufficient space for installation– Unusual cross-tenancy metering– Embedded networking (under contract)

National Deployment - Data Analysis and Reporting
The smart meter interval data allows you to understand more about your sites
Analysing the data allows you to identify peak/off-peak consumption, developing an energy index, sites with issues, etc…
![Page 64: FMANZ gratefully acknowledges the support of our Gold Sponsors](https://reader036.vdocuments.us/reader036/viewer/2022081515/56814943550346895db68d39/html5/thumbnails/64.jpg)
National Deployment - Data Analysis and Reporting
What the data won’t tell you:
•The root cause of excessive consumption•Whether consumption behaviour is human or controlled
![Page 65: FMANZ gratefully acknowledges the support of our Gold Sponsors](https://reader036.vdocuments.us/reader036/viewer/2022081515/56814943550346895db68d39/html5/thumbnails/65.jpg)
National Deployment - Data Analysis and Reporting
While Meridian are developing a web based portal for reporting and data analytics, Westpac were keen to realise the benefits of smart meter data. The reporting tool is based on a scoring system which rates the performance of each site on performance criteria:•Energy Index (benchmarked and scaled)•Peak average (benchmarked and scaled)•Off peak average (benchmarked and scaled)•Consumption on weekends/public holidays
![Page 66: FMANZ gratefully acknowledges the support of our Gold Sponsors](https://reader036.vdocuments.us/reader036/viewer/2022081515/56814943550346895db68d39/html5/thumbnails/66.jpg)
National DeploymentData Analysis and Reporting
Benchmarking figures:•Energy Index – 161•Peak average – 9 kwh•Off peak average – 3 kwh
These benchmarking figures are derived from the smart meter data. Poor performing sites were removed from this calculation.
