Why the UK's Power Grid is Sidelining Clean-Energy Battery Storage The administrators of Great Britain's power grid admit that it's often unable to use energy-storage batteries due to old computer systems and an old network with "not enough cables", according to the Financial Times — though the system operator says they're making progress after upgrading their system last December:
The company has plans to lower the rate at which batteries are sidelined to single figures by early next year [said Craig Dyke, from National Grid's electricity system operator], calling current levels "higher than where we want them to be". Dyke's comments came in response to a letter from four leading battery storage groups which said National Grid's "electricity system operator" or ESO division was making the country's power costlier and dirtier by failing to use their technology properly. "Consumers are paying more, clean renewable energy is being wasted, and fossil fuel generation is being used instead," they said... depriving them of revenue and undermining investor confidence.
While the U.K. has the world's second-largest offshore wind market, the article notes that when the system operator can't send its power where it's needed, "the ESO pays wind farms in one place to switch off... and can also need to pay gas-fired power plants in another area to turn on.
These payments add up to hundreds of millions of pounds each year, and the costs are passed on to household and business energy bills."
"Use of battery storage abroad has soared in places such as California, where batteries soak up solar power during the day and regularly supply a fifth of the state's power in the evening..."

GM Electric Vehicles Can Now Use Tesla Superchargers The Washington Post reports that electric vehicles made by General Motors now can use Tesla's Superchargers. (GM's charger adapters "will first be made available to customers in the United States, followed by availability for Canadian customers later this year.") The Post writes that the move "expands the number of vehicles compatible with the North American Charging Standard developed by Tesla" — and also marks "another step forward for efforts to settle on a universal public charger network for battery-powered cars and trucks in the U.S.
"It could also allay some GM customers' concerns about a lack of charging options."
The new changes take effect immediately, along with sales of the GM-approved power adapters... The deal makes roughly 17,800 Tesla Superchargers available to drivers of GM-manufactured vehicles such as the Chevy Bolt, Cadillac Lyriq and Silverado EV, with the help of an adapter that costs $225... GM estimates that the partnership with Tesla contributes to an overall network of 231,800 fast chargers across the United States available to drivers of its vehicles. GM is also part of IONNA, a joint venture of eight automakers that plans to build at least 30,000 high-powered chargers nationwide.
GM's statement calls it "a move that will help accelerate fast and convenient charging options for current and future EV drivers." And the move comes 15 months after GM announced it was adopting the standard — a move followed within weeks by similar announcements from Rivian, Ford, Volvo, Nissan, Hyundai and Kia. "Ford and Rivian have started distributing adapters for their EVs," the Washington Post points out, "while others, such as BMW, Honda, Hyundai and Mercedes-Benz have promised to start making their vehicles compatible this year or next."
"Knowing we will now have access to Tesla Supercharger locations means that range anxiety has now virtually evaporated..." argues a Chevy owner at CleanTechnica:
This is mostly good news for drivers of electric cars from GM. Tesla and The General have been bitter enemies in the past, with GM opposing Tesla's direct sales model in many states. The once fierce battle has cooled in recent years, but GM essentially won by keeping Tesla from selling direct to the public in several US states, including its new home of Texas. Nevertheless, the two companies are now cooperating, which is a bonus for drivers...
Despite some niggling concerns, this is a big deal for EV drivers in North America. Tesla Superchargers are the gold standard in the industry today. There are fast, reliable, and always located in clean, well-lit places where restrooms and fresh foods are available. This could very well change the conversation about electric cars to the point where by the time GM, Ford, and Stellantis get their plug-in hybrids into showrooms, the demand for them will have shrunk considerably.
One GM executive says in this week's statement that "GM's ongoing efforts to help accelerate the expansion of public charging infrastructure is an integral part of our commitment to an all-electric future."
