Enough wind power was curtailed in 2020 to power a million homes for a year

Is anyone in UK government circles going to take this seriously, as compensation (constraint) payments spiral upwards? The perpetual mismatch between supply and demand of wind power can only get worse as more of it is built. Energy storage can’t resolve these problems, only reduce them slightly at best.

Enough wind power was curtailed in 2020 to power a million homes for a year, reports Energy Live News.

A new report produced by Lane Clark & Peacock LLP (LCP) says primarily as a result of network constraints, last year saw a total of 3.6TWh of wind power shut off and wasted.

It claims if an extra 20GWh of battery storage was installed across the country, the amount of wind power wasted annually could be reduced by up to 50% – it says storage capacity must be ‘rapidly-scaled’ in order to avoid wasting large volumes of renewable energy in the future, which increases costs and reduces the proportion of the energy mix that can be generated without relying on fossil fuels.

The research forecasts that wind curtailments in Scotland and England will cost consumers as much as £1 billion per year by 2025 and notes this is likely to grow, considering the government’s commitment to quadruple the amount of offshore wind capacity to 40GW by 2030.
