    Brief

    The Nuclear Decommissioning Authority (NDA) is seeking an economic operator to deliver energy generation and trading optimisation services for the Maentwrog Hydroelectric Power Station, a 28MW hydroelectric plant. The successful supplier will be responsible for trading available energy generation capacity in the wholesale market, leveraging fundamental and technical analysis, market expertise, and operational data including water volumes, rainfall measurements, and generation forecasts. Services must operate within defined operational parameters to maximise revenue generation. The NDA aims to increase income from this asset to support its nuclear decommissioning mission. The contract is anticipated to run for an initial 2-year term with two optional 12-month extensions (up to 4 years total). The estimated contract value ranges from £240,000 to £500,000 for the initial term, with potential total income of £480,000 to £800,000 over the full 4-year period, subject to market conditions and supplier performance. Interested suppliers are invited to provide feedback on the forthcoming tender.
