Res-Intel Selected As SDG&E’s Metered Energy Savings Consultant

Res-Intel beat out considerable competition to become San Diego Gas and Electric’s (SDG&E) net metered energy consumption (NMEC) program evaluator. NMEC measures energy savings at the meter, as opposed to using industry standard deemed savings or custom modeling methods.

Meter-based savings is a new metric for energy conservation measure (ECM) performance that is results-driven, and will lend greater insight into program design and performance. For instance, program level meter-based savings can be measured in close to real-time with advanced metering infrastructure. This timely feedback can inform adjustments to program implementation throughout the program cycle, which can yield better program performance. Meter-based savings will also make for pay-for-performance program design practical. Implementors will only be paid for measured savings, rather than estimated, producing greater motivation to implement high performance programs.

Res-Intel will begin by performing NMEC evaluations of SDG&E’s Multifamily and Retrocommissioning HOPPs programs and will continue to develop methods and models for measuring savings across their portfolio. Res-Intel uses multivariate regression models and machine learning methods to provide modeling validity and accuracy.
