I thank my noble friend for his question and I share his desire to ensure good value for money for taxpayers and indeed passengers. The advice given in the KPMG report is that while the wholesale price for electricity is forecast to increase over the long term, the price of renewable energy is coming down, so it recommended signing a long-term contract for the supply of renewable electricity. I should reiterate that the report represents only advice to HS2. No decision has been made and, before any contract is signed, HS2 will need to present the proposed energy strategy to the DfT. Whatever strategy is agreed, HS2 Ltd will be required to demonstrate that it has complied with the Utilities Contracts Regulations 2016.
