Economics Of Grid Defection. When And Where Distributed Solar Generation Plus Storage Competes With Traditional Utility Service

This first installment of two reports outlines the possible scenarios in five different U.S. regions—Hawaii, California, Kentucky, Texas and New York—and identifies when solar PV and storage combinations could disrupt existing utility business models. The continuing decline of solar PV and battery storage costs, coupled with increasing retail electricity prices, has resulted in grid parity today for commercial customers in Hawaii. The most optimistic projections, based on certain solar and efficiency targets being met, depict grid parity for millions of residential and commercial customers in New York and California within this decade.
