Plaid Cymru’s energy spokesman Luke Fletcher said: “In our first 100 days in government, we would build new partnerships between government and key stakeholders and develop Trydan Gwyrdd Cymru into a single, consolidated energy company to develop renewables and to help reduce energy bills”.

Reform UK Wales’s manifesto includes a ban on new onshore wind farms and solar farms saying the country had “reached saturation point with unreliable, weather-dependent renewables that blight the Welsh countryside”.

A spokesperson said the party had also “announced plans to bring down energy bills by taking on green subsidies that have been piling misery on households”.

The Welsh Conservatives spokesperson for energy, Samuel Kurtz, said renewables “will play a role in our future energy mix, alongside reliable sources such as oil, gas and nuclear”.

“The priority must be ensuring that these projects deliver tangible outcomes: skilled jobs, investment and clear benefits for local communities,” he said.

The party was “committed to supporting the growth of marine energy, including floating offshore wind, while also advancing nuclear opportunities at Wylfa and Trawsfynydd,” he added.
