Offshore wind is now so damn cheap it gets *negative* subsidies in Europe.

Back in September 2019, the UK auctioned 5.5 GW of offshore wind at record-low prices. @Innogy_UK, @SSE & @Equinor will build for less than £40/MWh.
That's less than half the price @EDFenergy will get for their nuclear reactor at Hinkley Point C

But offshore wind was meant to be really expensive, right?
Historically, yes. But we found that prices are coming down by a staggering 12% per year when you look at all the recent auctions for capacity across Europe.

This shows how much money wind farms expect to receive over their lifetime. You can think of it as levelised *revenue*, rather than the usual levelised cost of electricity.
Farms built from 2022 will run for under €50/MWh (summing their revenue from power markets + subsidy)

What does this mean for the amount of subsidy that offshore wind farms will receive? Well, that depends on who should pay for the long transmission cables that connect them to the grid…
Maybe you think society should pay, because transmission is part of the electricity network (which the state pays for).
Then Germany and Netherlands have zero-subsidy farms (auctioned back in 2017) and the UK’s recent ones are paying €10/MWh back to consumers.

Maybe you think developers ought to pay for their grid links, because they are part and parcel of the wind farm (and farms should pay for the costs created).
Even then, the latest UK farms are very close to zero subsidy.

But, the level of subsidy also depends on future power prices. If prices fall, wind farms will claim money back off the government. If prices rise, then wind farms will be even better value in the future.
Predictions are hard… especially ones about the future…

Over the last decade, UK power prices have risen 1% faster than inflation. If that carries on, then the latest wind farms will pay back €5/MWh to the public purse (if they should pay for the grid link)… or €20 for every MWh they generate (if society should pay).
Not bad!
Not bad!
So…
Offshore wind is now a cost competitive form of electricity in mature markets.
Auctions have helped bring the prices down very fast.
Big targets, such as 40 GW offshore wind by 2040 from @BEISgovuk are looking better than ever!
