Lapsed planning permissions and terminated CfDs mean renewables are not quick to deploy
DAVID TURVER
Introduction
One argument that the Greens use against nuclear power is that it is “painfully slow”, implying that renewables are quick to deploy. Think tanks like Ember are forever talking about fast deployment of renewables. But is it really true that wind and solar are quick to deliver? I have done some digging into the Government’s Renewable Energy Planning Database (REPD) and what has happened to the projects awarded Contracts for Difference (CfDs) under the various allocation rounds to find out.
The planning database contains a list of thousands of renewables projects dating back decades. We might expect there to be a delay between granting planning permission and construction start. Therefore, for the purposes of this analysis, only those projects granted permission between 2008 and 2020 have been analysed, selecting those that are not under construction and not operational. The results are shown in Figure 1 below.
There are about 4.6GW of onshore wind projects with planning permission granted between 2008 and 2020 that are yet to start construction. These comprise some 237 projects in total and for 130 of them the planning permission appears to have expired before June of this year. There are a further 48 projects with no planning permission expiry date listed, but the permission was granted more than four years ago so they are unlikely to go ahead.
Offshore wind has about 4GW of offshore wind projects: Seagreen, Inch Cape and Hornsea Project Three that have yet to start construction. There are also 62 dedicated biomass projects with planning permission and are yet to start construction with a combined capacity of 3.6GW. The vast bulk of these projects were granted permission in 2013 or before and therefore it is obvious they are not going to get built.
A further 2.1GW of Battery Storage and 2GW of pumped storage projects are waiting to be built. Advanced Conversion Technologies (ACT) appear to have died a death because all but one of the ACT projects granted a CfD have been terminated and the one remaining ACT project does not appear to have generated anything. Planning permission for most of the Energy from Waste (EfW) projects seems to have expired and the Swansea Tidal Lagoon project has not gone ahead.
It is almost as if planning permission is granted, then developers get cold feet and cannot follow through with their projects. The lack of available grid connection points might be part of the reason these projects do not go ahead. However, the requirement for lots of connections for low density energy sources like wind and solar is a feature of the technology, not a bug.
Performance of CfD Projects
As you might expect, there is quite a lot of overlap between the REPD and the CfD contracts that have been awarded. However, the various databases published by the Low Carbon Contract Company (LCCC) allow a more granular examination of the status. By far the largest technology for CfDs in terms of capacity is offshore wind followed by solar and onshore wind.

The Liberty Beacon Project is now expanding at a near exponential rate, and for this we are grateful and excited! But we must also be practical. For 7 years we have not asked for any donations, and have built this project with our own funds as we grew. We are now experiencing ever increasing growing pains due to the large number of websites and projects we represent. So we have just installed donation buttons on our websites and ask that you consider this when you visit them. Nothing is too small. We thank you for all your support and your considerations … (TLB)
