Guidehouse partnered with Arizona Public Service to provide integrated evaluation and program planning for the utility’s demand-side management portfolio
Arizona Public Service (APS) needed a partner to provide measurement, evaluation, and research (MER) services in support of the planning and implementation of its demand-side management (DSM) portfolio. This requires:
Guidehouse began conducting research concurrent with the implementation of energy efficiency programs by APS. Guidehouse’s MER services are based on extensive measurement and verification activities including engineering analysis, field metering, onsite inspection, customer surveys, contractor and trade ally interviews, focus groups, billing records analyses, and review of implementation tracking databases and documentation. Through the MER process, Guidehouse provides ongoing evaluation to APS in separate measure-analysis spreadsheets, analytic databases, memos, reports, and presentations.
APS files its annual progress reports and implementation plans based on Guidehouse’s MER findings and recommendations. The findings inform the utility’s savings claims, cost-effectiveness estimates, lost fixed cost recovery, and performance incentives for the current program year, and program planning savings and cost estimates for the following program year.
