Services
Specialist project delivery and technical advisory across the UK energy sector.
Complete Power Solutions provides senior-level expertise across the full project lifecycle — from development readiness and grid connection through to construction delivery, commissioning and handover. Our services are structured to meet the specific needs of developers, asset owners, EPC contractors and investors.
Project & Programme Management
Senior delivery leadership across complex, multi-stakeholder energy programmes.
We provide experienced project and programme management across BESS, onshore and offshore wind, transmission and distribution, and building services projects. Our approach combines rigorous programme discipline with clear governance structures, proactive risk management and transparent executive reporting — ensuring projects are delivered on time, within budget and to the required technical standard.
Typical Client Need
Clients who need senior delivery leadership without the overhead of a permanent hire, or who require independent programme oversight alongside an existing team.
Key Deliverables
Grid Connection Management
End-to-end coordination of grid connection applications and network operator interfaces.
Grid connection is one of the most complex and time-critical workstreams on any energy project. We manage the full connection process — from initial application and offer acceptance through to design coordination, interface management with NESO, Transmission Owners and DNOs, and final energisation. Our experience spans both transmission-connected and distribution-connected assets across multiple voltage levels.
Typical Client Need
Projects that lack a dedicated grid connection lead, or where the connection workstream is at risk of falling behind the wider project programme.
Key Deliverables
Grid Code & ONCC Compliance
Managed compliance journey from Energisation Operational Notification through to Final Operational Notification.
Grid Code compliance is a specialist discipline that requires detailed knowledge of the regulatory framework, the NESO compliance process and the technical requirements of the relevant Grid Code standards. We manage the full compliance journey — coordinating studies, maintaining the evidence register, managing witness testing and driving progression through EON, ION and FON milestones.
Typical Client Need
Projects where the technical team needs an experienced compliance manager to own the process and maintain momentum with NESO and the Transmission Owner.
Key Deliverables
Development Readiness Advisory
Bridging the gap between land or connection and investment or construction readiness.
Many energy projects stall between securing a grid connection offer or land option and reaching the point where they can attract investment or proceed to construction. We provide structured development readiness support — auditing the current position, identifying gaps, and building the delivery plan, procurement strategy and technical workstream coordination needed to advance the project.
Typical Client Need
Developers who have secured a connection or land position but are struggling to build the technical and commercial package required to reach financial close or EPC procurement.
Key Deliverables
Owner's Engineer & Client Representative
Independent technical oversight of EPC contractors on behalf of the asset owner or developer.
When an asset owner or developer appoints an EPC contractor, they need an experienced technical representative to protect their interests throughout design, procurement, construction and commissioning. We act as Owner's Engineer or Client Representative — providing independent design review, interface control, programme challenge and contractor performance oversight.
Typical Client Need
Investors, developers and asset owners who need an experienced technical counterpart to the EPC contractor, ensuring the project is built to specification and the client's interests are protected.
Key Deliverables
Project Assurance & Recovery
Rapid assessment and structured recovery for projects under pressure.
When a project is late, over budget or has unresolved technical interfaces, an independent and experienced view is essential. We provide rapid project health checks, critical-path reviews and structured recovery programmes — identifying the root causes of delay or cost overrun and providing clear, actionable recommendations at board level.
Typical Client Need
Boards, investors and senior leadership teams who need an independent assessment of a project in difficulty and a credible recovery plan.
Key Deliverables
EPC Procurement & Commercial Support
Technical and commercial support through EPC and BOP tender and negotiation.
Procuring an EPC or Balance of Plant contractor is one of the most consequential decisions on an energy project. We provide technical and commercial support throughout the procurement process — from scope development and tender documentation through to evaluation, clarifications, risk allocation and contract negotiation — ensuring the client secures the right contractor on the right terms.
Typical Client Need
Developers and asset owners who are tendering or negotiating EPC or BOP packages and need experienced technical and commercial support alongside their legal advisers.
Key Deliverables
Technical Due Diligence
Experienced delivery-side technical review for investors, funders and acquirers.
Technical due diligence on energy projects requires more than a desktop review of documents. We provide a delivery-experienced perspective — assessing the realism of the programme, the maturity of the design, the robustness of the EPC strategy and the credibility of the cost assumptions. Our reviews are structured to give investors and funders a clear view of technical risk and deliverability.
Typical Client Need
Investors, lenders and acquirers who need an independent technical view of a project's deliverability before committing capital.
Key Deliverables
Project Controls & PMO Setup
Governance frameworks and project controls infrastructure for growing energy developers.
As energy developers grow their portfolios, the need for consistent governance, reporting and project controls becomes critical. We design and implement PMO frameworks — establishing reporting templates, risk and change management processes, programme standards, decision gates and portfolio dashboards that give leadership teams the visibility they need across multiple concurrent projects.
Typical Client Need
Growing developers and asset managers who have multiple projects in flight but lack the governance infrastructure to manage them consistently and report confidently to investors and boards.
