Virginia Law

A. In all filings required by 20VAC5-318-30, the sources of all data or estimates used as inputs for proposed DSM measures or programs, in descending order of preference, shall be:

1. Utility-specific data;

2. Virginia-specific data if utility-specific data is unavailable or impracticable. When Virginia-specific data is used, the utility shall provide an explanation as to why utility-specific data is unavailable or impracticable;

3. Data from non-Virginia jurisdictions or sources, if neither utility-specific data nor Virginia-specific data is available or practicable:

a. When data from non-Virginia jurisdictions or sources is used, the utility shall provide an explanation as to why utility-specific data is unavailable or impracticable.

b. When data from non-Virginia jurisdictions or sources is used, the utility shall provide an explanation as to why Virginia-specific data is unavailable or impracticable as well as the sources of all data, to include:

(1) Titles, version numbers, publication dates, and page numbers of all source documents, as appropriate; and

(2) An explanation as to why, in the utility's assessment, use of this data is appropriate.

B. EM&V reports shall include relevant workpapers, support documents, assumptions, and equations used in developing the measurement and verification methodologies of measures or programs reported.

C. EM&V reports shall include measure-level estimates of kilowatt, kilowatt-hour, dekatherm, and pipeline capacity savings as appropriate. An estimate that has been adjusted for free-ridership as well as an estimate that has not been adjusted for free-ridership should be included as appropriate.

D. Generally, EM&V of DSM programs or measures should comply, as appropriate, with Options A, B, C, or D from the International Performance Measurement and Verification Protocol (January 2012). However, the commission recognizes that each utility has unique characteristics, and new or modified DSM measures are constantly being developed. As such, alternative methodologies may be considered with sufficient supporting documentation and explanation of appropriateness.

E. Utilities are encouraged to consider use of emerging technologies, including "advanced measurement and verification" or "evaluation, measurement and verification 2.0" when appropriate and cost effective.
