Behind-the-Meter Solar PV, Energy Storage Set to Shift Calif. Time-of-Use Rates

utility microgrids

In California, it can get expensive and complex for utilities to deliver electricity when demand is high. To help mediate these costs, California's utilities offer time-of-use (TOU) rates, prices for power based on demand trends on the grid. A new white paper from Enel X explores how behind-the-meter solar PV and energy storage are aligning to … [Read more...]
