California’s biggest investor-owned utilities are expected to de-energize power lines more frequently this year to stop them from igniting fires when the weather is dry and windy. It’s one of the fastest and cheapest ways for utilities to keep wildfires from sparking. But there’s an obvious downside: Whole communities can go dark for hours or even days. With those concerns in mind, some energy companies are urging state officials to incentivize microgrids and smaller standalone energy systems, such as rooftop solar paired with batteries, in fire-prone communities. Those technologies, the companies say, could help keep the lights on during preemptive power shutoffs.
