In 2011 London Underground carried out a tender process to develop a framework for the deployment of solar PV. However, it was at this time that the Government significantly reduced the Feed In Tariffs, meaning the project was no longer financially viable. The relatively high capital costs mean that any project is heavily dependent on the level of Feed-In-Tariff available as savings from direct generation are not sufficient.

In 2014 the Department of Energy and Climate Change released several consultations and an updated strategy looking at solar PV deployment. Their stated intent is to encourage more commercial roof generation (such as that available on the TfL estate) through increased support from Feed-In-Tariffs. These developments are being monitored to understand how they can increase the opportunity for the deployment of solar PV.
