Transport for London (TfL) is aiming for all of its rail services to be zero carbon by 2030. The principles of TfL’s Energy and Carbon Strategy and feasibility work undertaken to date are outlined in two submissions to TfL’s Safety, Sustainability and Human Resources panel:

As part of this and responding to points i and ii, TfL has considered the potential benefits of demand side response and electricity storage and is continuing to monitor the market to assess such schemes. The opportunity to deploy energy storage as a complementary measure to renewables such as solar photovoltaic is limited for most  London Underground (LU) sites due to large electricity consumption across LU’s private power network.

TfL is involved in two demonstration projects to further understand opportunities for stationary battery storage and vehicle-to-grid technology to balance supply with demand. These projects seek to understand the commercial case for deploying each technology at scale to maximise renewables and lower costs of upgrading and operating electricity networks.

With regard to point iii, TfL issued a prior information notice (PIN) in October 2018 concerning “potential opportunities to connect directly with existing or imminently and viably developed suppliers”. TfL also completed a study through the GLA’s DEEP framework in 2019 to assess the potential for sites adjacent to London Underground’s network to host large scale solar photovoltaic. TfL is using the outputs of these studies to inform its approach to procurement.
