National Grid blames old computer systems for sidelining BESS20 Sep 2024 16:26
From an article in the FT a few days ago.
Ageing computer systems and an outdated electricity network means National Grid is often unable to use batteries designed to deliver cheap green power, it has admitted.
Batteries were being overlooked by Britain’s network operator up to 30 per cent of the times when they are cheaper than other power sources, Craig Dyke, from National Grid’s electricity system operator, said.
“We do still acknowledge we still have more work to do,” he said, blaming a range of technical factors including outdated computer equipment at the network operator and not enough cables to send electricity to where it was needed.
The company has plans to lower the rate at which batteries are sidelined to single figures by early next year, he said, 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.
