(Bloomberg) — First they struck California, then Texas. Now blackouts are threatening the entire U.S. West as nearly a dozen states head into summer with too little electricity.
From New Mexico to Washington, power grids are being strained by forces years in the making — some of them fueled by climate change, others by the fight against it. If a heat wave strikes the whole region at once, the rolling outages that darkened Southern California and Silicon Valley last August will have been previews, not flukes.
“It’s really the same case in different parts of the West,” said Elliot Mainzer, chief executive officer of the California Independent System Operator, which runs most of the state’s grid. “It’s revealed competition for scarce resources that we haven’t seen for some time.”
