Electricity tariff to TfL entities for train traction
Dear Transport for London,
I am interested to know some information regarding the electricity tariff that you (or any of your sub-entities - LUL, etc) pay to your supplier. I am specifically interested in the energy used for traction by electric trains, and am not interested in the energy for other services, e.g. signalling, stations, etc. However, if this information cannot be disaggregated I am happy to accept answers for the aggregated system.
1) Do you pay a 'time of use' tariff, i.e. is it more expensive to power trains during peak periods than it is during off-peak periods?
2) Is your supply tariff based on total energy use, or peak power demand, or a combination of both? I am interested to know whether there is any monetary incentive from the supplier for you to reduce your peak power demand.
I appreciate that the details of your agreement with your supplier are likely commercially sensitive, which is why I have tried to keep my questions to general effects. I am trying to gain an understanding of the market forces upon you, in relation to traction energy for trains.
Please do let me know if I need to clarify my questions.
Yours faithfully,
A Smith

Dear A Smith
Our ref: FOI-0375-2021/GH
Thank you for your request received by Transport for London (TfL) on 10
June 2020 asking for information about electricity tariffs.
Your request has been considered under the requirements of the Freedom of
Information Act 2000 and our information access policy. I can confirm that
we do hold the information you require.
1) Do you pay a 'time of use' tariff, i.e. is it more expensive to
power trains during peak periods than it is during off-peak periods?
Yes. Multiple elements of the TfL electricity bill are based on time of
use with the most expensive time being the evening peak period on a Winter
weekday.
2) Is your supply tariff based on total energy use, or peak power
demand, or a combination of both? I am interested to know whether there is
any monetary incentive from the supplier for you to reduce your peak power
demand.
The majority of charges levied on TfL are consumption based. However, some
others are based on electrical demand during discrete periods. These
charges can be reduced/avoided if you are able to reduce electrical demand
or switch off.
If this is not the information you are looking for, please do not hesitate
to contact me.
Please note, the Government has announced a series of measures to tackle
the coronavirus. It is essential for London, that we continue to provide a
