Labour’s ‘rooftop revolution’ to deliver solar power to millions of UK homes | Solar power

Keir Starmer’s new Labour government today unveils plans for a “rooftop revolution” that will see millions more homes fitted with solar panels in order to bring down domestic energy bills and tackle the climate crisis.

The energy secretary, Ed Miliband, also took the hugely controversial decision this weekend to approve three massive solar farms in the east of England that had been blocked by Tory ministers.

The three sites alone – Gate Burton in Lincolnshire, Sunnica’s energy farm on the Suffolk-Cambridgeshire border and Mallard Pass on the border between Lincolnshire and Rutland – will deliver about two-thirds of the solar energy installed on rooftops and on the ground in the whole of last year.

Now, before Wednesday’s king’s speech, which will include legislation for setting up the new publicly owned energy company GB Energy, Miliband is working with the building industry to make it easier to buy new homes with panels installed, or instal them on existing ones.

The Observer understands that ministers are looking at bringing in solar-related standards for new-build properties from next year. Another possible idea is that developers may be asked to provide a certain number of new homes with solar panels as part of any development.

At present, while formal planning permission is not required, there are restrictions on where and how high up on buildings they can be placed. There are also restrictions in conservation areas and on listed buildings. These may potentially also be re-examined.

Miliband, who has promised to triple the amount of solar power in the UK by 2030, as well as double onshore wind and quadruple offshore wind, said on Saturday night: “I want to unleash a UK solar rooftop revolution. We will encourage builders and homeowners in whatever way we can to deliver this win-win technology to millions of addresses in the UK so people can provide their own electricity, cut their bills and at the same time help fight climate change.”

His officials insisted the new government was showing its willingness to “take on the Nimbys” as part of the fight against the climate crisis.

As one of his first acts last week, Miliband lifted the Tories’ de facto ban on the building of new onshore windsfarms.

Miliband’s rapid moves on solar power were hailed by UK energy experts, who said they would speedily rectify a huge imbalance in the use of renewable energy in Britain.

At present, most power from renewable sources is concentrated in the north but has to be transmitted to the south, where demand is most intense. “Unfortunately, these transmission lines are congested and power supplies from the north to the south are often curtailed,” said Sugandha Srivastav, of Oxford University’s Smith School of Enterprise and Environment.

“Instead, gas generators have to be turned on to provide electricity for households in the south, and as we all know, after the Russian invasion of Ukraine, gas can be extremely expensive. So solar in the south is going to fix a key problem. It will keep power costs low, which is what we desperately need.”

In addition, the opening of the Gate Burton, Sunnica and Mallard Pass solar farms will increase the nation’s capacity for using solar radiation to generate electricity. “The three farms will have a capacity of around 1.35 gigawatts, which is almost 10% of current capacity – so this is very welcome,” said Hamish Beath, an energy consultant at Imperial College London.

However, the decisions have caused local outcries. The Tory MP for Rutland and Stamford, Alicia Kearns, said she was “utterly appalled” by Miliband’s decision to give the go-ahead to the Mallard Pass farm.

The government hit back, saying the move was justified on the grounds it will provide clean energy to power about 92,000 homes over the next 60 years.

Opening the door to more large solar power farms will have to be quickly followed by improvements to the National Grid, experts also say. “We need to think urgently about how we transmit and distribute electricity,” added Srivastav. “The demand for power is only going to go up as we electrify society and if we cannot get electricity to where it needs to be, we will be in an untenable situation.”
