New rolling blackout hits at least 200,000 customers

One of California’s three biggest utilities says it is cutting power to at least 200,000 customers in the northern and central parts of the state. The move by Pacific Gas & Electric Saturday night comes as a heat wave baking California in triple-digit temperatures continued to strain the electrical system. The California Independent System Operator (California ISO), which manages the power grid, declared a need for the rolling power outage at 6:30 p.m. The authority previously said it didn't expect to issue more rolling blackouts Saturday.
