TfL Ref: FOI-0220-2122 Thank you for your request received by Transport for London (TfL) on 2nd May 2021 asking for information about Greenwich Power Station. Your request has been considered in accordance with the requirements of the Freedom of Information Act and our information access policy. Specifically you asked: “I would like to receive up-to-date information on the power output of Greenwich Power Station, which I believe is owned by TfL for use for the London Underground. The same request was raised and accepted in Sept 2014. Reference: FOI-0999-1415 If possible, it would be very interesting to know: 1) the electricity generated per month 2) the number of times per month that the turbines have been switched on 3) TFL'S plans for future use of the Greenwich Power Station according to the new ambition for a zero-carbon, 100% renewable energy using railway by 2030?” Please see the attached spreadsheet showing the electricity generated per month, which has been updated to the end of 2020. The turbines are turned on once per month on average for up to 2 hours. We are currently undertaking a review of what the future of the power station may be in providing the emergency back-up power supply to the railway. The timescales are as yet uncertain. If this is not the information you are looking for, or if you are unable to access it for any reason, please do not hesitate to contact me. If you are considering submitting a further FOI request please think carefully about whether the request is essential at this current time, as answering FOI requests will require the use of limited resources and the attention of staff who could be supporting other essential activity. Where requests are made, please note that our response time may be impacted by the current situation. Please see the attached information sheet for details of your right to appeal as well as information on copyright and what to do if you would like to re-use any of the information we have disclosed. Yours sincerely, David Wells FOI Case Officer FOI Case Management Team General Counsel Transport for London
