Self-Generation Incentive Program—Measurement and Evaluation Reports

Impact Evaluations

Analyses of the impacts of the SGIP in each year of operation. Areas of assessment include: Electrical energy production and demand reduction; operating and reliability performance characteristics; electrical, thermal and overall efficiencies and the contribution of SGIP technologies to electricity system efficiency and reliability; the impact of employment of renewable fuels by SGIP technologies; the extent to which SGIP technologies provide net greenhouse gas (GHG) emissions reductions; and the relationship between DG technologies and operation, and T&D system performance and operations.

Process and Retention Evaluations (including PA Comparative Assessments)

Analyses of SGIP processes and the interaction between these processes and current market needs. Process evaluations and PA comparative assessments include reviews of administrative styles and processes, marketing and outreach, implications of different approaches, and external variations. Retention studies assess the long-term persistence of impacts from self-generation technologies, and find the technical degradation factor (time and use related change in efficiency) and the effective useful life (the median number of years that the technologies are still in place and operational).

Cost-Effectiveness Studies

Assessments of the cost-effectiveness of the SGIP, based on SGIP-specific projects and incentive structures. The September 2005 preliminary cost-effectiveness assessment was based on the cost-effectiveness analysis framework report (posted below) using metered project performance information. In accordance with that framework, cost-effectiveness was evaluated from three perspectives: participant (project owners within the SGIP), nonparticipant (ratepayers), and society as a whole. The 2007 report on solar PV costs and incentive factors is intended to provide information on metered PV performance and reported PV system costs for PV systems implemented under the SGIP, and is meant to examine the relationships of PV performance, cost, and incentive design.

Renewable Fuel Use Reports

Assessment of the extent to which SGIP technologies employ renewable fuels. Reports include analysis of the compliance of renewable fuel use projects receiving incentives under the SGIP with renewable fuel use requirements, identification of the operational and cost characteristics of RFU projects, and evaluation of the implications of increased renewable fuel use on the SGIP.
