The requirement covers technical support for managing and overseeing a wind energy asset portfolio, including continuous monitoring of wind turbines and assessment of their performance. The appointed provider is expected to oversee operation and maintenance activities and ensure they follow applicable industry standards, recognised good practice and contractual obligations. This is a services contract in the repair, maintenance and public utilities field, with delivery in the South West of England. It is relevant to windfarm operators, renewable energy asset managers, engineering consultancies and technical service providers with expertise in turbine performance, operational oversight and maintenance assurance for public-sector energy assets. The procurement is complete and was awarded through a direct award. The award was made to Constellia Public Limited on 22 July 2026 for £209,000 including the stated contract value. The contract runs from 1 August 2026 to 31 March 2031. The tender submission deadline was 22 July 2026 at 23:59. Bristol City Council is the buying organisation. The requirement was classified as repair and maintenance services, with public utilities as an additional classification, and is identified as suitable for small and medium-sized enterprises. The selected supplier is Constellia Public Limited. The published outcome therefore records a single active award for the windfarm management and technical oversight service. This award demonstrates a defined requirement for specialist oversight of a substantial wind energy asset portfolio by Bristol City Council. A credible competitor for comparable work would need practical wind turbine knowledge, the ability to monitor operational performance continuously and the technical capability to assess whether maintenance and operating activities meet industry standards, good practice and contractual requirements. Relevant suppliers are likely to combine renewable-energy engineering expertise with asset-management, monitoring, reporting and compliance assurance skills. The opportunity is suitable for an SME, indicating that delivery does not necessarily depend on the scale of a major national contractor. Firms able to provide dependable technical support, identify performance issues and oversee maintenance obligations would be well placed when this requirement next reaches the market. ## Notice Avonmouth Energy Park - Windfarm Management Provision of specialised technical support services to Bristol City Council for the management and oversight of a PS5 million wind energy asset portfolio.
