California Governor Gavin Newsom has declared a state of emergency to address power grid concerns as the western US faces an extreme heat wave, Report informs, referring to Fox News.

Parts of California and a handful of regions in other western states have seen record daily highs this week, with temperatures soaring up to 118 degrees (47.7C).

The move – citing “extreme heat peril” – will ease restrictions on backup generators, auxiliary engines and other sources of carbon-powered electricity as the state braces for a sweltering weekend.

Newsom and state utility leaders were widely criticized during a heatwave last summer when more than 200,000 Californians suffered two days of rolling power outages – the first time residents had to deal with such issues in nearly 20 years.

Fuel consumption and air-quality restrictions on utility companies are also being rolled back during the emergency.
