20 Va. Admin. Code § 5-304-30 - Minimum guidelines for data input and modeling assumptions

Current through Register Vol. 38, No. 3, September 27, 2021

Minimum guidelines to provide direction to electric and natural gas utilities in developing applications for approval of DSM programs are as follows:

1. That the assumptions used in developing projected input data and the models used in the integrated resource planning process should be identified and well-documented. Utility-specific data should be used whenever possible (e.g., unit performance data, end-use load research data, market research data, etc.). In cases where utility-specific data are not available, the assumptions must be clearly defined;
2. That historic data, if available, should be assessed in developing projected data. Significant departures from historic trends should be explained;
3. That each projected data series should represent the Company's most current forecast;
4. That computer modeling techniques should be used in the development of an integrated resource plan;
5. That estimates of the capital and O&M (operation and maintenance) costs of supply-side options should include realistic projections of the costs of compliance with all promulgated environmental regulations or enacted legislation from which environmental regulations will be promulgated;
6. That each assumption and/or projected data series should be consistent with all other assumptions and/or projections. Consistency of data should be maintained between all models used within the integrated resource planning process; and
7. That alternative projections to determine sensitivity to input assumptions should be developed. These alternative projections should be used to perform cost/benefit analysis.

Waiver of strict adherence to these guidelines for small utilities or those in unusual circumstances may be granted by order of the Commission.
