THE newest wave of UK offshore wind farms could produce power so cheaply that they pay money back to consumers, researchers have said.

As offshore wind was rolled out in UK waters, it faced criticism that it required high levels of subsidies, pushing up people’s energy bills.

But experts from Imperial College London say the most recently approved offshore wind farms will most likely operate with “negative subsidies”, which will pay money back to the Government and reduce bills.

Their analysis, published in the journal Nature Energy, suggests the UK will see the world’s first negative-subsidy offshore wind farms in the mid-2020s. In the UK, the cost of offshore wind energy has plummeted in just a few years from around £150 for each megawatt hour (MWh) of electricity generated to £40 per MWh in the latest auctions In 2019.

Under the auction process, projects compete for contracts which guarantee a certain price, known as the “strike price”. If this is lower than the wholesale electricity price, the company has to pay back the difference.

Lead researcher Dr Malte Jansen said: “Offshore wind power will soon be so cheap to produce that it will undercut fossil-fuelled power stations and may be the cheapest form of energy for the UK.”
