Solar + Storage Synergies for Managing Commercial-Customer Demand Charges

Pieter Gagnon, Galen Barbose, Naim Darghouth, Andrew Mills, Anand Govindarajan, Lori Bird

Research output: NRELTechnical Report


We study the synergies between behind-the-meter solar and storage in reducing commercial-customer demand charges. This follows two previous studies that examined demand charge savings for stand-alone solar in both the residential and commercial sectors. In this study we show that solar and storage show consistent synergies for demand charge management, that the magnitude of reductions are highly customer-specific, and that the magnitude of savings is influenced by the design of the electricity tariff.
