Project Objectives

Review and update BPA’s site-specific M&V protocols

– Reference• National best practices• BPA’s efficiency resource acquisition activities

Project Status

• Make recommendations for revising and augmenting protocols (Phase 1) – BPA has received the final report– Utility focus group formed.

• Revise or develop new protocols (Phase 2)– Underway. Complete 6/1/10

• Follow-on research (Phase 3)– To be started. Complete 9/30/10

Research Activities• Interview 25 stakeholders

– BPA staff and contractors, utility staff, NPCC staff• Review BPA’s M&V protocols and national best practices

– Best Practices • IPMVP, ASHRAE Guideline 14-2002

– Example Protocols• FEMP, PJM, CA Standard Performance Contract,

CA Commissioning Collaborative– Example Deemed Measures and Savings Calculators

• Efficiency Vermont TRM, CA DEER– Example Evaluation Guides

• National Action Plan, CA Evaluation Protocols– National Trends

• North American Energy Standards Board, NEEP EM&V Forum, Increased availability of time-stamped and end-use data

Findings – Stakeholders Agree:• BPA’s site-specific protocols are generally working well

from a process perspective• Contacts have confidence in the measured and verified

savings• BPA should move toward classifying as custom a smaller

proportion of projects needing the Standard M&V Plan– Move projects into Light M&V, Simplified protocols (inc. deemed

savings calculators), and deemed savings

Slide 7

B O N N E V I L L E P O W E R A D M I N I S T R A T I O N

Findings – Analysis of BPA project Data

• Data entry into PTR not constrained to pre-determined measure types– Assumptions and re-coding needed to analyze PTR data

• M&V protocol used was not evident• Current project unable to assess variance of ex ante

from ex post savings estimates by measure type / size– Awaits follow-on work

Slide 8

B O N N E V I L L E P O W E R A D M I N I S T R A T I O N

Findings – Protocol Review:• Protocols are reasonable, yet fall short of being IPMVP-

adherent; should be revised– Not surprising, since protocols developed prior to IPMVP!

• Additional protocols would be useful

Slide 9

B O N N E V I L L E P O W E R A D M I N I S T R A T I O N

Recommendations• BPA should revise its protocols to be IPMVP-adherent.

Include:– Identifying the IPMVP Option– Requiring documentation of baseline equipment and operating

characteristics– Expanding description of calculations to be used, data to be

collected, and use of data in calculations– Provide additional detail, e.g., selecting monitoring points,

sampling, and generally addressing questions that often arise

Slide 10

B O N N E V I L L E P O W E R A D M I N I S T R A T I O N

Recommendations, Cont.• Phase 2 of this project is developing/ revising 5 to 6

protocols from among:– End-use metering (revision)– Energy use indexing (revision)– Existing building commissioning (new)– M&V protocol selection (new)– Sampling (new)– Regression (new; for analyzing time-series data in support of

site-specific M&V)

Slide 11

B O N N E V I L L E P O W E R A D M I N I S T R A T I O N

Recommendations, Cont.• Use of M&V light for eligible projects• Bring together the region’s M&V protocols and savings

assurance tools in a single repository– Sampling instructions, formulas, default assumptions, key

reference materials, deemed savings calculators, protocols• Improve documentation of M&V activities

– Time spent and protocol used• Improved PTR entries

– Standardize measure type, identify protocol used, tracking of ex ante savings

Slide 12

B O N N E V I L L E P O W E R A D M I N I S T R A T I O N

Recommendations, Cont.• Address process issues stakeholders identified

– Simplify processes by which utilities upload their efficiency information into the PTR

– Align responsibility and authority within BPA for approving M&V plans and final savings estimates

– Bring cost documentation requirements in line with risk, focusing on higher-cost elements

Slide 13

B O N N E V I L L E P O W E R A D M I N I S T R A T I O N

Follow-on research (Phase 3)– Research current use of M&V light and appropriate uses

going forward– Assess risk per measure type / size by estimating variance of

ex ante from ex post savings estimates– Coordinate M&V policies and procedures with evaluation

strategy and activities• M&V and evaluation should work in tandem to understand risk

and how to address risk cost-effectively
