Mayor of London Sadiq Khan has set out plans to change the way the Transport for London (TfL) Tube network is supplied with electricity and make the move towards a greater use of renewable energy.

 

The aim is that all electricity requirements for the London Underground are met via zero-carbon sources by 2030.

 

Environment strategy

 

All passenger rail services operated by TfL are electrically powered and, as part of the London Environment Strategy, the mayor has set TfL the goal of achieving a zero-carbon railway by 2030.

 

TfL is one of the largest consumers of electricity in the UK, with a requirement for 1.6TWh per annum, equivalent to the electricity consumed by more than 437,000 homes. It currently sources electricity directly from the National Grid via the Crown Commercial Service.

 

By developing plans to purchase power from renewable generators through power purchase agreements (PPAs), TfL would enable the rail network to be supplied by energy sources including wind and solar power, rather than a mix of power generators that emit carbon into the atmosphere.

 

The market testing will explore all elements of these contracts so TfL can secure a good deal for London and will also look at the potential for meeting the GLA group’s wider demand for renewable electricity – a total of 143 GWh which includes Greater London Authority (GLA), London Fire Commissioner (LFC), Transport for London (TfL), Mayor’s Office for Policing and Crime (MOPAC), London Legacy Development Corporation (LLDC) and Old Oak Common and Park Royal Development Corporation (OPDC).

 

“As one of the single biggest purchasers of energy in London, it is important that TfL leads the way on green energy. This is a vital step towards my ambitions for TfL – and London – to be zero-carbon by 2030,” said Khan.

 

He added: “Covid-19 has had a devastating impact but as we recover we want to make sure that we build a better, greener and more equal city. This work to secure cost-effective and renewable energy for the rail network, with ambitions to include the wider GLA group and beyond, will play a key role in London’s green recovery and accelerating action on the climate emergency.”

With the current financial challenges facing TfL, the mayor wants to ensure that the energy used to power its rail network is both cost effective in the long-term and taken from clean sources. The intention is to start with a TfL PPA with energy generators in a phased approach, with the ambition of considering purchasing up to 10 per cent of its demand by Spring 2022 subject to market testing and approval from TfL’s finance committee later this year.

 

Wider demand

 

The mayor will also look at opportunities to meet London’s wider public sector electricity demand with renewables, helping achieve zero carbon faster through collaboration with London’s local authorities’ offices, schools and leisure centres. In total these organisations along with the GLA group currently consume around 3TWh of electricity every year – equivalent to the electricity consumed by more than 820,000 homes which is 22 per cent of homes across London.

 

“As one of the largest electricity consumers in the UK, we have a duty to explore fully the contribution that renewable energy can make to running our services,” said chief safety, health and environment officer at TfL, Lilli Matson. “This early market engagement will help us better understand generator preferences, their impact on price and their ability to decarbonise our future power requirements.”

 

The introduction of renewable PPAs is one of a number of initiatives underway at TfL to help reduce carbon emissions and improve air quality. For example, waste heat from the London Underground network has been providing heating and hot water to more than 1,350 homes, a school and two leisure centres in Islington since earlier this year thanks to a pioneering energy centre at Bunhill, and TfL is talking to the wider market about potential future opportunities across its network.
