    "description": "Ground-Mounted Solar PV System at Brymbo Heritage CentreIntroductionBrymbo Heritage Trust (the \u00e2\u0080\u009cEmployer\u00e2\u0080\u009d) is seeking proposals from suitably qualified and experienced Engineering, Procurement, and Construction (EPC) Contractors for the delivery of a ground-mounted solar photovoltaic (PV) system with an export capacity of up to 180 kW AC, together with provision for a battery energy storage component, at the Site with a 400 V grid connection, located adjacent to the Brymbo Heritage Visitor Centre.This Invitation to Tender (ITT) provides an opportunity for Contractors to participate in the design, supply, installation, testing, and commissioning of a fully operational solar PV facility. The project represents the first phase of a larger planned renewable energy development, providing scope for future expansion and energy storage integration.The Employer is committed to delivering a high-quality, sustainable, and safe renewable energy installation that maximises energy generation within the planning and technical constraints, aligns with local and national regulatory requirements, and contributes to broader environmental and social objectives. This procurement will be conducted in accordance with Welsh public procurement principles, including compliance with the Social Partnership and Public Procurement (Wales) Act 2023 and relevant guidance under the Well-being of Future Generations (Wales) Act 2015.Planning and Grid ConnectionPlanning approval for the project was granted on 1 December 2025 under application reference P/2024/1578, subject to a number of conditions. Full planning details, including the list of conditions and associated documents, remain available on the Council\u00e2\u0080\u0099s planning portal, and tenderers are expected to review and comply with all planning requirements when preparing proposals.A grid connection offer has been provided by SP Energy Networks (SPEN), confirming the technical feasibility of connecting the proposed system to the local electricity network. Tenderers must consider the SPEN connection offer in the design, costings, and overall project delivery plan, ensuring that the system is compatible with the local distribution network and capable of delivering reliable power export.Scope of WorksThe primary objective of this tender is to deliver a fully compliant and operational solar PV array, designed to maximise generation capacity while remaining fully within the approved planning envelope and SPEN grid connection constraints. The selected EPC Contractor will be responsible for delivering the project from design to completion, providing all services, materials, equipment, and documentation necessary to ensure the works are completed to the highest technical, regulatory, and safety standards.Modular Approach and Battery StorageWhile the initial focus of the project is the delivery of the solar PV array, the Employer intends for the system to be implemented using a modular approach that enables integration of battery energy storage at this stage and a system that can be expanded in due course. Tenderers are therefore requested to:- Prioritise delivery of a high-performance PV system, maximising generation capacity within the planning and technical constraints.- Demonstrate how battery storage can be integrated now and in subsequent phases with minimal redesign or operational disruption.- Provide itemised costs, technical specifications, and integration options for battery storage, enabling the Employer to make informed decisions on staged deployment.This approach ensures that the PV array can operate at full capacity immediately, while providing flexibility for energy storage expansion as funding, programme considerations, or operational requirements permit.Project TimingThe EPC contract is anticipated to be awarded by end of January 2026, with detailed design and construction activities commencing immediately thereafter. Tenderers are required to provide realistic programme schedules that reflect all stages of the project, including design, procurement, construction, testing, commissioning, and handover. Key milestones should be clearly identified, demonstrating the Contractor\u00e2\u0080\u0099s ability to deliver the project on time and within the agreed parameters.Post-Construction ServicesFollowing completion of the works, the Contractor may be required to provide warranty support and Operations \u0026 Maintenance (O\u0026M) services for a minimum period of two years, with the option for contract extensions beyond this period. Tenderers should outline their approach to post-construction support, including:- Monitoring and reporting system performance- Preventative maintenance schedules- Rapid response to operational or technical issues- Support for potential future battery integrationThis ensures the long-term reliability, efficiency, and safety of the solar PV installation.Opportunity SummaryThis ITT represents a unique opportunity for qualified EPC Contractors to deliver a high-quality, grid-connected solar PV system that contributes to local renewable energy capacity and sustainability objectives. The project forms the first phase of a larger development, offering potential for future expansion and energy storage deployment. Tenderers are encouraged to submit proposals that balance technical excellence, value for money, and long-term operational performance, while demonstrating innovation, reliability, and social value consistent with Welsh public procurement principles.Submission RequirementsPlease refer to the Bidding Document for full details and templates.Site visits will be taking place on Monday 5th January 2026.
