We\u2019re committed to overcoming the challenges of nuclear clean-up and decommissioning, leaving the 17 nuclear sites ready for their next use. We do this work with care for our people, communities and the environment, with safety, as always, our number one priority. We also play an important role in supporting government\u2019s aspiration for the UK to be a global leader in the civil nuclear sector. We strive to deliver best value for the UK taxpayer by focusing on reducing the highest hazards and risks, while ensuring safe, secure, and environmentally responsible operations at our sites. We seek ways to reduce the level of public funding from government by generating revenue through our commercial activities.\nMaentwrog Hydroelectric Power Station (\u201cMaentwrog\u201d) is a 28MW hydroelectric plant owned by NDA and operated by Magnox Limited (\u201cMagnox\u201d).\nThe NDA is seeking to engage with economic operators obtain feedback regarding a forthcoming tender to appoint an economic operator to deliver energy generation and trading optimisation services for the NDA\u0027s Maentwrog Hydropower station asset. The core service to be delivered includes, but is not limited to the provision of trading available energy generation capacity within the wholesale market, based upon fundamental and technical analysis, market expertise and available generation capacity based upon water volumes, rainfall and available measurements within defined operational parameters.\nThe aim of this procurement is to increase income generation to support the NDA in delivering it\u0027s mission.\nIt is anticipated that the agreement may be based upon a 2 year initial term with 2 twelve month optional extensions.\nIt is anticipated that the total contract value will be circa \u00a3240,000 and \u00a3500,000 for the initial term, with a potential income value between \u00a3480,000 and \u00a3800,000 across a potential total 4-year term, subject to Supplier performance. Please note, we appreciate that income will change based upon market conditions and fluctuations, therefore these are indicative estimates.",
