Evaluation, Measurement and Verification (EM&V) plays an important role in planning and operation of the Conservation programs at the OPA. EM&V is the undertaking of studies and activities aimed at assessing the impacts (e.g. energy and demand savings) and effectiveness of a Conservation program on its participants and/or the market.

The Integrated Power System Plan points to EM&V as the mechanism behind making Conservation a reliable and sustainable resource. EM&V will provide regular feedback about Conservation program performance and will lead to better estimates of Conservation potential and the development of more effective programs and activities to secure it.

The Evaluation Framework document, represented in Figure 1, provides the background for a consistent and systematic method for tracking, reporting and evaluating the impacts and effectiveness of Conservation programs funded by the OPA. The individual components, which together form the Evaluation Framework, are described in detail in the supplemental documentation provided.

The OPA plans on completing evaluations for all programs it manages. The assessments will verify the net energy and peak demand savings achieved, consider the impact of buyers and sellers in the market, and make suggestions around program design and delivery system improvements.

The OPA has created an EM&V business unit that will oversee the independent evaluation of conservation program activities and their reported results in fulfilling these functions. Accurate, reliable and verified results will help in arriving at effective and objective decisions with regards to Ontario’s energy future.
