Capacity market: battery and DSR will be used for backup power from the grid next winter

Clean energy facilities, including rechargeable batteries, demand response and pumped-up hydraulic accumulators, are among those used to provide back-up power to the UK grid next winter, as the government signed contracts worth around £ 380 million at the last auctioned off the power market yesterday.

The auction has raised prices to provide important standby electricity to help keep the lights on for 2022/23. the peak of winter periods.

All of the power requested at the auction – just under 5 GW – was concluded at a record price of £ 75 per kilowatt, well above the previous record at the 45-pound power auction, the National Grid confirmed in its preliminary results yesterday.

As expected, gas-fired power plants bought out reserve capacity contracts for a lion’s share of more than 3.3 GW, only SSE took out nearly £ 170 million contracts for three of its gas stations, while coal-fired power plants also received more than 400 MW. -the value of contracts in the power market.

However, there have also been big gains for clean networking technologies: demand-responsive contracts have increased contracts for back-up capacity of more than 500 MW, battery capacity of 385 MW and 85 MW hydraulic accumulator.

Energy from landfills also won deals to provide more than 100 MW of backup electricity next winter, while onshore wind and solar installations were used to provide about 15 MW of power. show preliminary auction results.

Power market auctions have been held by the government since 2014 in an attempt to protect the grid during periods of peak demand in the winter as more and more periodic energy sources, such as wind and solar, come into the grid.

But Jess Ralston, an analyst with the Energy and Climate Intelligence Unit (ECIU), said the government had built up additional back-up electricity for next winter because “traditional nuclear, gas and coal-fired power plants have proved unreliable.”

“This capacity auction will add a few pounds to the bills, an amount less than £ 500, which adds high gas prices,” she said. “At the same time, cheaper renewables are reducing our dependence on volatile fossil fuels and have to save more than £ 600 million on electricity costs during this gas crisis.”

The auction comes amid rising energy bills caused by global gas shortages, prompting calls for faster deployment of domestic renewables to reduce dependence on volatile international fossil fuel markets.

Last week, the government announced plans to hold more frequent auctions for renewable energy subsidy contracts, which he said would help boost internal energy security while speeding up the transition to cleaner energy sources.

This happened when Energy Minister Greg Hands said that after the government’s new plans to auction for differences every year, not every two, he expected renewables to be “on track to supply most of the electricity by 2030”.

In a written statement Yesterday at the House of Commons, Hands said: “Renewable electricity generation has more than quadrupled since 2010, accounting for more than 40 percent of production in 2020, for the first time ahead of fossil fuels, and is on track to supply most electricity by 2030.” .
