    Brief

    Ofgem is seeking supplier support to evaluate Long Duration Electricity Storage (LDES) projects competing for Cap & Floor Licences. The work includes: (1) assessing technical project parameters and value for money of proposed costs submitted in Window 1; (2) designing technical policy and reporting frameworks for Window 2; (3) post-Final Investment Decision reviews to ensure best value for consumers, particularly when projects face unexpected costs from force majeure events, regulatory changes, or unidentified risks; and (4) critical analysis and refinement of policies and processes to improve future project assessments. This role is essential to Ofgem's statutory duty to protect consumer interests. Suppliers should have expertise in engineering assessment, cost-benefit analysis, risk evaluation, and regulatory policy design for energy storage infrastructure.
