Solar powers fossil-fuelled generation to record low

Another solar generation record of 14,426 megawatts was set at 11.30 on 22 April, delivering 37% of Great Britain’s electricity and contributing to a record low reliance on fossil fuels. According to figures from the National Energy System Operator, natural gas accounted for exactly 2% of Great Britain’s electricity supplies at 11.30 and at midday, generating a comparatively tiny 799MW.[1]

Households on agile energy tariffs enjoyed negative pricing.

A new low for gas generation was also seen at 14.00 the same day, falling to only 420MW, or 1.2% of the electricity mix. At the same time, solar accounted for 35% of Great Britain’s electricity, supplying 11,933MW at the time.

But the record did not stand for long. Only a day afterwards, the cool, bright weather led to a gigawatt more being generated – equivalent to the power of two typical nuclear reactors. At midday on 23 April, an estimated 15,420MW of sunshine-fuelled power was online, supplying 42% of power.

“What was once thought to be impossible is today’s reality: a grid being dominated by cheap, zero-carbon energy. This will become the norm as renewables grow ever faster, powering the economy and driving down prices for us all,” said Chris Hewett, Chief Executive of Solar Energy UK.

An earlier record was set on 7 April, at 14,414MW.[2]
