AS many as 17 separate bids for North Sea renewables projects have been given the green light around Scotland's coast.

There's big money behind them and big corporations looking to harness the profit potential of offshore wind through the ScotWind leasing round.

Together, the projects are capable of generating electricity equivalent to more than twice Scotland's national needs.

Nicola Sturgeon says this is "transformational" and Highlands and Islands Enterprise has compared the potential economic impact to the oil and gas boom.

Here's a rundown of what they are, where they are, how much power they can generate and who is behind them.

The data's been published by Crown Estate Scotland as part of its announcement into the bid process – the first since the process was devolved to Scotland.

The bid process is the first in a decade and the results come two months after the COP26 climate summit was held in Glasgow.

But nothing's been built yet and neither have the deals been fully signed-off. Applicants still have to commit to a full agreement and if any of these fail, replacement deals could be struck with runner-up applicants.

After that, each project will be subject to consenting, financing and planning processes.

Simon Hodge, chief executive of Crown Estate Scotland, said: "In addition to the environmental benefits, this also represents a major investment in the Scottish economy, with around £700m being delivered straight into the public finances and billions of pounds worth of supply chain commitments.

"The variety and scale of the projects that will progress onto the next stages shows both the remarkable progress of the offshore wind sector, and a clear sign that Scotland is set to be a major hub for the further development of this technology in the years to come."
