California Tests Off-the-Grid Solutions to Climate-Related Power Outages

California's energy commission has funded dozens of projects "serving as test beds for policies that might lead to commercialization of microgrids," reports the Associated Press: When a wildfire tore through Briceburg nearly two years ago, the tiny community on the edge of Yosemite National Park lost the only power line connecting it to the electrical grid. Rather than rebuilding poles and wires over increasingly dry hillsides, which could raise the risk of equipment igniting catastrophic fires, the nation's largest utility decided to give Briceburg a self-reliant power system. The stand-alone grid made of solar panels, batteries and a backup generator began operating this month. It's the first of potentially hundreds of its kind as Pacific Gas & Electric works to prevent another deadly fire like the one that forced it to file for bankruptcy in 2019. The ramping up of this technology is among a number of strategies to improve energy resilience in California as a cycle of extreme heat, drought and wildfires hammers the U.S. West, triggering massive blackouts and threatening the power supply in the country's most populous state... "I don't think anyone in the world anticipated how quickly the changes brought on by climate change would manifest. We're all scrambling to deal with that," said Peter Lehman, the founding director of the Schatz Energy Research Center, a clean energy institute in Arcata. The response follows widespread blackouts in California in the past two years that exposed the power grid's vulnerability to weather. Fierce windstorms led utilities to deliberately shut off power to large swaths of the state to keep high-voltage transmission lines from sparking fire. Then last summer, an oppressive heat wave triggered the first rolling outages in 20 years. More than 800,000 homes and businesses lost power over two days in August. During both crises, a Native American reservation on California's far northern coast kept the electricity flowing with the help of two microgrids that can disconnect from the larger electrical grid and switch to using solar energy generated and stored in battery banks near its hotel-casino. As most of rural Humboldt County sat in the dark during a planned shutoff in October 2019, the Blue Lake Rancheria became a lifeline for thousands of its neighbors: The gas station and convenience store provided fuel and supplies, the hotel housed patients who needed a place to plug in medical devices, the local newspaper used the conference room to put out the next day's edition, and a hatchery continued pumping water to keep its fish alive... During a few hours of rolling blackouts last August, the reservation's microgrids went into "island mode" to help ease stress on the state's maxed-out grid... State facilities are planning to quadruple the amount of battery storage from 500 megawatts to 2,000 megawatts by this August. But unfortunately, "There are setbacks too: An intensifying drought is weakening the state's hydroelectric facilities..."
