Title: Energy Efficiency As A Resource Option Three Decades of PNW Experience


1
Energy Efficiency As A Resource Option Three
Decades of PNW Experience
  • Tom Eckman
  • Northwest Power and Conservation Council

National Association of Regulatory
Commission Energy Resources and the Environment
Committee July 22, 2009
2
What Youre About To Hear
  • What Weve Done
  • 30 years of using energy efficiency as a resource
  • Why We Did It
  • Using Integrated Resource Planning to make the
    business case for utility reliance on energy
    efficiency as a resource
  • How We Know What We Did
  • Standardizing Evaluation, Measurement and
    Verification
  • What Were About To Do
  • Goals for the coming decade

3
Northwest Speak (Definitions)
  • Average Megawatt (aMW) 8760 MWH
  • Conservation Any reduction in electric power
    consumption as a result of increases in the
    efficiency of energy use, production or
    distribution.
  • Curtailment Sitting in a dark, hot house,
    drinking warm beer

4
The Evolution of Energy Policy
October 11, 2002 President Carter Awarded Nobel
Peace Prize
April 18, 1977 Conservation means a cold dark
house President Carter announces we are engaged
in the moral equivalent of war (MEOW)
December 5, 1980 - Conservation declared a
resource equivalent to generation President
Carter signs Northwest Power and Conservation Act
5
Northwest Power and Conservation Planning Act of
1980 (PL96-501)
  • Authorized States of ID, OR, MT and WA to form an
    interstate compact (aka, The Council)
  • Directed the Council to develop 20-year load
    forecast and resource plan (The Plan) and
    update it every 5 years
  • The Plan shall call for the development of the
    least cost mix of resources
  • The Plan shall consider conservation (energy
    efficiency) its highest priority resource
    equivalent to generation with a 10 cost
    advantage over power generating resources
  • Mandated public involvement in Councils planning
    process.

6
How Has It Worked?
7
Utility Reaction to Councils First Plan Was
Mixed
8
Three Decades of Utility Conservation
Acquisitions (aka Mr. Toads Wild Ride for
the PNWs Energy Efficiency Industry)
See http//en.wikipedia.org/wiki/Mr._Toad's_Wild_
Ride
9
Nevertheless Since the Late 70s
Since 1978 Utility BPA Programs, Energy Codes
Federal Efficiency Standards Have Produced Almost
3600 aMW of Savings.
Weve Accomplished Mass Quantities
10
So Whats 3600 aMW?
  • Its enough electricity to serve more than the
    entire state of Idaho and all of Western Montana
  • It saved the regions consumers nearly than 1.6
    billion in 2007
  • It lowered 2007 PNW carbon emissions by an
    estimated 14.1 million tons.

11
Energy Efficiency Is The Regions Third Largest
Resource
Weve Saved The Equivalent to Almost Two Grand
Coulee Dams
12
So How Did We Make The Case ?
13
Two Methods
  • Integrated Resource Planning (IRP)
  • Systematic evaluation of the least cost/least
    risk portfolio of resource choices where energy
    efficiency is treated equivalent to generating
    resources
  • Energy Efficiency Resource Portfolio Standards
  • Mandated minimum share of energy efficiency
    resources

Portfolio Analysis on One Slide
16
So How Do You Know You Did That?
17
The PNWs Approach To Standardization of
Savings Measurement Verification (Were Not
California)
  • Established An Ongoing Centralized Process for
    Technical Review
  • Carried out by Regional Technical Forum (RTF)
  • RTF composed of utility and non-utility
    engineering and economic experts, staffed by
    Council
  • Funded by Bonneville Power Administration,
    utilities and system benefits administrators
  • Public process
  • RTF builds on historical program experience and
    ongoing evaluations of regional acquisition
    programs

18
RTFs Major Functions
  • Establish a Standardized Regional
    Cost-Effectiveness Methodology
  • Public domain software for evaluating
    cost-effectiveness
  • Recommend Measurement and Verification Protocols
  • Use IPMVP, ASHRAE, FEMP, NAPEE Model Energy
    Efficiency Program Impact Evaluation Guide
  • Develop tailored MV Protocols for custom, but
    recurring projects (e.g. grocery store
    refrigerated case retrofits)
  • Develop and Maintain Internet-based System for
    Tracking and Reporting Regional Energy Efficiency
    Savings and Expenditures
  • Deemed savings (with minimum technical
    specifications Q/C criteria)
  • EMV protocols
  • Default inputs for cost-effectiveness evaluations
    (e.g., forecast of future energy prices, cost of
    deferrable distribution and transmission, value
    non-energy benefits such as water savings, etc.)
  • Forecast CO2 content/kWh saved (based on load
    shape of savings)

19
RTFs Major Functions
  • Process for updating deemed savings as technology
    and standard practices change.
  • Appeals process
  • Utilities or other parties, including vendors,
    can demonstrate that different savings and value
    estimates should apply
  • Collaborative Development of EMV protocols for
    programs operated across multiple utility service
    areas

20
Measure Screening Process
Deemed Savings and Cost-Effectiveness
All Possible Measures
Online Planning, Tracking Reporting System Data
Base
Deemed Calculated Savings and Cost-Effectiveness
Screening Criteria Cost- Effectiveness Analysis
Custom Project Valuation, Measurement and
Verification Protocols
21
Online Planning, Tracking and Reporting System
  • Designed to assist utilities and contractors
  • Identify potential energy efficiency measures and
    programs eligible for utility and/or SBC
    administrator programs.
  • Track progress toward savings goals using
    standardized values and protocols
  • Report energy efficiency activity status to
    utility/SBC administrator management and
    regulators

22
Major Components of the PNW Online System
  • Two-Way System
  • Users download deemed savings, calculators
    protocols/custom project reports
  • Users upload results
  • Business Rules
  • Reporting periods
  • Verification requirements
  • Software Platform

Targets
30
Impact of The Plan
  • Meet Nearly All of Load Growth Over the Next 20
    Years With Energy Efficiency at an Average Cost
    of Less Than 40 MWH
  • This Will Require Sustained and A Much Larger
    (2x-3x) Investment In Cost-Effective Energy
    Efficiency
  • Over the first five-years it will reduce regional
    revenue requirements by 1 - 1.5 as a result of
    reduced power market purchases
  • Accomplishing the Almost Draft 6th Plans
    Conservation Goals Will Stretch the Columbia
    River
  • In five years well build the equivalent of
    another Chief Joseph dam,
  • In 12 years, well build the equivalent of Chief
    Joseph, plus Grand Coulee dams
  • In 20 years, we will have added the equivalent of
    50 to the output of all hydroelectric
    resources in the PNW

Carbon Emissions From the Northwest Power System
Will Be Below 1990 Levels
