Energy Efficiency Terminology
Demand side management – three major components– Energy efficiency– Load management– Conservation
Conservation versus efficiency– Behavioral changes versus installed
technology

Why Choose Energy Efficiency?
Cost of saving electricity with energy efficiency efforts in 2007– 2.6¢/kWh
Cost of comparable electric supply in 2007– 10.7¢ / kWh

Early Efficiency Programs
Most programs targeted to homes with electric heat– Conducted energy audits– Electric hot water heater jackets– Weatherization
Load control devices on electric hot water heaters
![Page 6: NARUC Energy Regulatory Partnership Program The Georgian National Energy Regulatory Commission](https://reader036.vdocuments.us/reader036/viewer/2022062500/56815a22550346895dc765bd/html5/thumbnails/6.jpg)

Early Board Policy on Efficiency
1990, Board issued an order finding:– Energy efficiency programs could meet a
significant portion of present and future load– Utilities needed to take energy efficiency
programs seriously and treat equivalently to supply options
– Energy efficiency programs could be improved to produce better results
– A comprehensive energy efficiency program was needed
Solution – least-cost integrated resource planning
![Page 7: NARUC Energy Regulatory Partnership Program The Georgian National Energy Regulatory Commission](https://reader036.vdocuments.us/reader036/viewer/2022062500/56815a22550346895dc765bd/html5/thumbnails/7.jpg)

Pre-EEU History
22 franchised distribution utilities providing retail service in separate territories (now 20) – 5 (now 3) investor-owned distribution utilities– 2 member-owned distribution utilities
(cooperatives)– 15 municipal government distribution utilities
Electric distribution utilities were obliged to deliver electric energy efficiency services
Utilities delivered within their own territories, via own personnel or contractors
![Page 8: NARUC Energy Regulatory Partnership Program The Georgian National Energy Regulatory Commission](https://reader036.vdocuments.us/reader036/viewer/2022062500/56815a22550346895dc765bd/html5/thumbnails/8.jpg)

Improving Energy Efficiency Efforts in Vermont
Statewide coordination of efforts – contact one organization for efficiency services
Spread the efficiency message to all ratepayers across the state and combine savings results
Provide customers of small utilities with same opportunity for energy efficiency savings as customers of large utilities
Board process to create the EEU resulted in a settlement among utilities, public advocates, and many intervenors
![Page 10: NARUC Energy Regulatory Partnership Program The Georgian National Energy Regulatory Commission](https://reader036.vdocuments.us/reader036/viewer/2022062500/56815a22550346895dc765bd/html5/thumbnails/10.jpg)
10
Creation of the EEU in 2000
Statewide program designs– Uniformity of program structure, incentives– Statewide costs used for screening
Single delivery entity, the Energy Efficiency Utility, for majority of state ratepayers– Contractor to Public Service Board; not franchised– Barred from delivery of power
– Efficiency Vermont Burlington Electric Department delivers same
programs within its locality; cooperation required
![Page 11: NARUC Energy Regulatory Partnership Program The Georgian National Energy Regulatory Commission](https://reader036.vdocuments.us/reader036/viewer/2022062500/56815a22550346895dc765bd/html5/thumbnails/11.jpg)

Roles of State Agencies
Public Service Board– Hires (after RFP process) Efficiency Vermont,
Contract Administrator, Fiscal Agent– Approves Efficiency Vermont’s Annual Plans– Approves payment of any performance
incentives– Establishes total EEU program budget and
energy efficiency charge rates– Reports to legislature annually on the
revenues collected via the energy efficiency charge and EEU program expenditures

Roles of Other Entities
Advisory Committee– Consists of representatives of stakeholder
groups appointed by Board– Meets at least quarterly to provide advice to
Efficiency Vermont– Purely advisory, no managerial authority
Electric distribution utilities– Provide information to and receive data from
efficiency utility– Retain active obligation to deliver efficiency to
address system constraints; may hire efficiency utility to do so
![Page 15: NARUC Energy Regulatory Partnership Program The Georgian National Energy Regulatory Commission](https://reader036.vdocuments.us/reader036/viewer/2022062500/56815a22550346895dc765bd/html5/thumbnails/15.jpg)

EEU Services
Address key markets:– Business new construction– Existing businesses– Residential new construction– Existing homes– Retail efficient products (lighting and
appliances) Initiatives target certain types of customers
– For example: ski areas, schools, multi-family housing, state buildings, low-income
![Page 17: NARUC Energy Regulatory Partnership Program The Georgian National Energy Regulatory Commission](https://reader036.vdocuments.us/reader036/viewer/2022062500/56815a22550346895dc765bd/html5/thumbnails/17.jpg)
EEU Services
Market-based approach– Focus on market-driven opportunities for
energy efficiency– Identify and focus on those who make and
influence efficiency decisions– Work via existing market structures that
are recognized and used by customers Retailers and Suppliers Architects and Engineers Trade Associations
![Page 18: NARUC Energy Regulatory Partnership Program The Georgian National Energy Regulatory Commission](https://reader036.vdocuments.us/reader036/viewer/2022062500/56815a22550346895dc765bd/html5/thumbnails/18.jpg)

Funding
The EEU is funded by a non-bypassable volumetric wires charge known as the Energy Efficiency Charge (“EEC”) that is shown separately on customers’ bills
Statewide charge set by customer class The Board determines the total budget
for the EEU program and the amount to be collected via the wires charge
![Page 19: NARUC Energy Regulatory Partnership Program The Georgian National Energy Regulatory Commission](https://reader036.vdocuments.us/reader036/viewer/2022062500/56815a22550346895dc765bd/html5/thumbnails/19.jpg)

How the Dollars Flow Each distribution utility bills its customers
the EEC Each utility sends the Fiscal Agent the total
amount of EEC billed (not collected) the prior month, along with certain accounting forms
The Fiscal Agent pays invoices that have been approved by the Contract Administrator and certain taxes that are collected as part of the EEC
In the following year, there is a “true-up” for utility EEC uncollectibles
![Page 20: NARUC Energy Regulatory Partnership Program The Georgian National Energy Regulatory Commission](https://reader036.vdocuments.us/reader036/viewer/2022062500/56815a22550346895dc765bd/html5/thumbnails/20.jpg)
20
Design of EEC Initially was a percent of bill
– Differed by utility service territory– Was the same for all customer classes in
each service territory Because underlying utility rates
differed, customers in different service territories were paying different amounts for EEU services
Low-usage customers paid a large amount of EEC compared to the savings they could realize from EEU services
![Page 21: NARUC Energy Regulatory Partnership Program The Georgian National Energy Regulatory Commission](https://reader036.vdocuments.us/reader036/viewer/2022062500/56815a22550346895dc765bd/html5/thumbnails/21.jpg)
21
Design of EEC (cont.) In 2003 moved to statewide kW and kWh
EEC charges, methodology refined in 2004, now described in a Board Rule– Allocate total EEC collections between
residential, commercial and industrial customers based on their contributions to utility revenues
– Determine kWh rates for each class– For commercial and industrial demand
customers, use energy/demand revenue split to determine portion of revenues to be collected via kW and kWh charges
![Page 22: NARUC Energy Regulatory Partnership Program The Georgian National Energy Regulatory Commission](https://reader036.vdocuments.us/reader036/viewer/2022062500/56815a22550346895dc765bd/html5/thumbnails/22.jpg)
22
EEU Budget
Statute requires the Board to consider the following objectives when determining the budget:– Reduce the need for future power purchases– Reduce the generation of greenhouse gases– Limit the need to upgrade the transmission and
distribution structure– Minimize the costs of electricity– Provide efficiency and conservation services as part of
a comprehensive resource supply strategy– Provide the opportunity for all Vermonters to
participate in the programs– Target efforts to markets where they may provide the
greatest value
![Page 23: NARUC Energy Regulatory Partnership Program The Georgian National Energy Regulatory Commission](https://reader036.vdocuments.us/reader036/viewer/2022062500/56815a22550346895dc765bd/html5/thumbnails/23.jpg)
23
EEU Budget (cont.)
Initial budget capped at $17.5 million Budgets ramped up and reached the
statutory cap in 2005 In 2005, new legislation removed cap;
Board increased 2006-2008 budgets 2008 Budget is $30.75 million:
approximately 4% of distribution utility retail revenues
2009-2011 Budgets: To be determined
![Page 24: NARUC Energy Regulatory Partnership Program The Georgian National Energy Regulatory Commission](https://reader036.vdocuments.us/reader036/viewer/2022062500/56815a22550346895dc765bd/html5/thumbnails/24.jpg)
24
EEU Budget Process
Board has used different procedures to establish budgets– Settlement agreement (years 1-3)– Administrative process, based in part on
DPS technical potential study (years 4-6 and 7-9)
– Contested case proceeding (year 4) Board is using an administrative
process to set the years 10-12 budgets
![Page 25: NARUC Energy Regulatory Partnership Program The Georgian National Energy Regulatory Commission](https://reader036.vdocuments.us/reader036/viewer/2022062500/56815a22550346895dc765bd/html5/thumbnails/25.jpg)
25
Performance Contract
3-year, performance-based contract, with option to renew for up to 3 more years
Performance indicators are an excellent tool for focusing Efficiency Vermont’s attention on Board’s policy goals
Well-designed performance indicators are easier to administer than detailed budget restrictions
![Page 26: NARUC Energy Regulatory Partnership Program The Georgian National Energy Regulatory Commission](https://reader036.vdocuments.us/reader036/viewer/2022062500/56815a22550346895dc765bd/html5/thumbnails/26.jpg)
26
Performance Contract (cont.)
Board determines policy objectives for EEU
Specific performance measures and goals are negotiated with contractor at the beginning of the contract
Portion of contractor’s pay is tied to achieving the performance goals ($2.347 million over 3-year contract)
![Page 27: NARUC Energy Regulatory Partnership Program The Georgian National Energy Regulatory Commission](https://reader036.vdocuments.us/reader036/viewer/2022062500/56815a22550346895dc765bd/html5/thumbnails/27.jpg)
27
Board’s Policy Objectives
Resource acquisition (primary focus) Market transformation Equity considerations
– Customer class– Geographic region
Board recognizes some of these objectives conflict with others– Performance goals provide guidance to
contractor on how to balance competing objectives
![Page 28: NARUC Energy Regulatory Partnership Program The Georgian National Energy Regulatory Commission](https://reader036.vdocuments.us/reader036/viewer/2022062500/56815a22550346895dc765bd/html5/thumbnails/28.jpg)
28
Board’s Policy Objectives (cont.)
Achieve maximum societal net benefits while acquiring comprehensive cost-effective electric efficiency savings
Respond appropriately to markets in order to increase the level and comprehensiveness of energy efficiency services to Vermonters
Effectively capture potential “lost opportunity” markets
Strive for distributional equity across customer classes and geographic regions
![Page 29: NARUC Energy Regulatory Partnership Program The Georgian National Energy Regulatory Commission](https://reader036.vdocuments.us/reader036/viewer/2022062500/56815a22550346895dc765bd/html5/thumbnails/29.jpg)
29
Recently Added Performance Goal for the EEU
Board directed Efficiency Vermont to target 40% of the EEU budget in certain defined geographic areas of the state that were experiencing transmission and distribution constraints
Goal is to reduce peak demand in the targeted areas
Defer the need for future transmission and distribution capacity investment
![Page 30: NARUC Energy Regulatory Partnership Program The Georgian National Energy Regulatory Commission](https://reader036.vdocuments.us/reader036/viewer/2022062500/56815a22550346895dc765bd/html5/thumbnails/30.jpg)
30
Performance Indicators
Cumulative annual electricity savings Total resource benefits – includes
electricity, fossil fuel, and water savings Summer & Winter peak kW demand
savings Program results incentives – direct
market impacts Community awareness
![Page 31: NARUC Energy Regulatory Partnership Program The Georgian National Energy Regulatory Commission](https://reader036.vdocuments.us/reader036/viewer/2022062500/56815a22550346895dc765bd/html5/thumbnails/31.jpg)
31
Performance Indicators (cont.)
All performance indicators are multi-year Many performance indicator awards are
scaled– Efficiency Vermont must achieve a minimum
level in order to receive any award for that indicator
– If Efficiency Vermont reaches the target, it earns 100% of the award for that indicator
– If Efficiency Vermont exceeds the target, it can earn more than 100% of the award for that indicator; however, the total performance award is capped
![Page 32: NARUC Energy Regulatory Partnership Program The Georgian National Energy Regulatory Commission](https://reader036.vdocuments.us/reader036/viewer/2022062500/56815a22550346895dc765bd/html5/thumbnails/32.jpg)
32
Minimum Performance Standards
Electric benefits must exceed costs; failure to meet means ineligible for any performance incentive
Minimum spending on residential customers; failure to meet reduces performance award cap by $359,100
Minimum low-income spending; failure to meet reduces performance award cap by $359,100
Minimum participation by small non-residential customers; failure to meet reduces performance award cap by $359,100
![Page 33: NARUC Energy Regulatory Partnership Program The Georgian National Energy Regulatory Commission](https://reader036.vdocuments.us/reader036/viewer/2022062500/56815a22550346895dc765bd/html5/thumbnails/33.jpg)
33
Process for Verifying EEU’s Performance
For annual electricity savings, total resource benefits, and summer and winter peak kW savings, each year:– Efficiency Vermont submits annual report that
establishes its claimed savings– DPS verifies the savings claims, makes
recommendation to Contract Administrator– Contract Administrator attempts to resolve any
disputes, makes recommendation to the Board– Board makes final determination regarding
Efficiency Vermont’s performance
![Page 34: NARUC Energy Regulatory Partnership Program The Georgian National Energy Regulatory Commission](https://reader036.vdocuments.us/reader036/viewer/2022062500/56815a22550346895dc765bd/html5/thumbnails/34.jpg)
34
Process for Verifying EEU’s Performance (cont.)
For other performance indicators, claims are made by Efficiency Vermont at end of three years, same verification process is followed
![Page 35: NARUC Energy Regulatory Partnership Program The Georgian National Energy Regulatory Commission](https://reader036.vdocuments.us/reader036/viewer/2022062500/56815a22550346895dc765bd/html5/thumbnails/35.jpg)
35
How Other States Deliver Energy Efficiency
Two primary funding mechanisms– Electric rates– Public benefits funds
Three types of entities delivering efficiency– Electric utilities – Third party administrators– Government agencies
Some states use a combination of funding mechanisms and delivery entities
