Energy storage can play an important role in a transition to clean energy, but only if it’s deployed within an effective policy framework. The Connecticut Public Utility Regulatory Authority (PURA) adopted our recommendations to target its energy storage incentives to areas with the highest differential between the highest and lowest marginal emissions rates so batteries could ultimately lead to reductions in emissions. In addition, PURA directed the Connecticut Green Bank to review our comments when setting the scope of the program's marketing plan.

The Connecticut Public Utilities Regulatory Authority (PURA) issued a straw program design for electric storage. We submitted comments that support PURA's efforts to make energy storage part of its overarching decarbonization agenda and provide feedback. It is important, as we explain, that PURA take into account the potential emissions consequences of energy storage operations in designing its performance-based incentive.

Connecticut’s Department of Energy and Environmental Protection (DEEP) and Public Utilities Regulatory Authority (PURA) are conducting a study to determine how it can best compensate distributed energy resources, like solar panels and residential battery installations, which can provide provide significant value to the grid. DEEP and PURA’s study involves an electric system dispatch simulation model and various DER technology use cases. We submitted comments on the model’s outputs and how they can be improved to better serve the study.

The Connecticut Department of Energy and Environmental Protection (DEEP) and Public Utilities Regulatory Authority (PURA) have proposed several quantitative and qualitative value categories it intends to examine in its study of the value of DERs. We submitted comments supporting their inclusion of avoided emissions costs, which covers both greenhouse gas emissions and ambient air pollutants, as a value category. We also encourage DEEP and PURA to include electricity system resilience among the quantifiable benefits of DER deployment.
