UK1 - Pipeline Notice
Summary of the contracting process

Transport for London (TfL) explored procuring renewable electricity through multiple virtual power purchase agreements (VPPAs) with renewable generators or counterparties. The proposed arrangement was for electricity generated by specified renewable facilities, with an additionality requirement. It was expected to use a pay-as-produced structure for solar or wind projects, including onshore and offshore wind, and new-build or repowered assets. The electricity would serve TfL’s needs across England, Scotland and Wales. This was a planned energy procurement, rather than a contract for construction or installation services in their own right.

TfL invited market feedback in March 2026, but did not commence a tender or invite bids. Following its review of market conditions, TfL ended this proposed procurement on 9 October 2026 and is considering using the Government Commercial Agency’s power purchase agreement framework instead. The planned VPPA arrangement envisaged projects supplying 40–250 GWh each, within a maximum annual volume window of 500 GWh (30% of TfL’s total volume). Supply was envisaged from October 2028 to December 2032, with fixed pricing linked to the Consumer Prices Index. The lot’s recorded contract period ran from 1 January 2028 to 1 January 2045. The market sounding questionnaire deadline was 6 April 2026 at midday.

The requirement was suited to renewable energy generators and power market counterparties able to structure and deliver virtual power purchase agreements. Relevant capabilities included originating or representing solar and wind generation, including onshore and offshore projects, and supporting new-build or repowered assets. Suppliers needed to address the requirement for additional renewable generation and a pay-as-produced supply structure, with fixed pricing linked to the Consumer Prices Index. The proposed individual project volumes point to an opportunity for businesses with access to substantial generation output or the ability to aggregate it. However, TfL did not proceed to tender for this virtual product; it is exploring a framework route for a physical power purchase agreement instead.
