Record Breaking Day for Wind

23 March 2013

  • Wind generates over 5 gigawatts of electricity for whole 24 hour period for the first time
  • Enough to power the equivalent of 4 out of every 10 British homes
  • Power was generated during one of the coldest March days on record and whilst gas price at 7 year high

RenewableUK is celebrating the fact that for the first time, wind energy in the UK generated over 5 gigawatts of electricity consistently over a 24 hour period, with the period starting on Thursday 21st March 2013 at 9:30pm and continuing for the rest of Friday 22nd March 2013.

This means that for this 24 hour period wind was generating enough to power the equivalent of nearly 4 out of every 10 UK homes and consistently over 10% of GB’s overall electricity needs.

In addition a record for one-off generation in a half hour period was created at 1530 when 5.296GW of wind was present on the grid, alongside another anticipated 2GW from distributed wind.

Maria McCaffery Chief Executive of RenewableUK said “What this shows is that wind is a stable and reliable source of power generation on the scale we need, when we need it most. This then counters the idea that wind does not generate power during cold snaps and comes at the same time as reports that the UK has only 36 hours of gas supplies in reserve, and on the day that the wholesale price of gas in the UK reached a seven year high. It also serves as a timely reminder of the vulnerability of supply and the price volatility of imported fossil fuels. This power production coupled with Ofgem’s own figures, announced on Thursday, which showed the real cost of wind to households is just over 3p a day is a double triumph of fact over fiction”.
