Case study
Solar Feasibility for NHS’ London Hospitals

As NHS Trusts continue with the rollout and delivery of the NHS Net Zero Carbon Delivery Plan, NHS England requested us to develop an investment grade solar feasibility study for six NHS sites in London.
Client
In 2023, it was estimated that NHS contributed to around 4% of the country’s carbon emissions and over 7% of the economy. This means the NHS has a critical role in meeting the net zero legislation targets under the Climate Change Act. The NHS, supported by the Greater London Authority, has set itself an aim to become the world’s first net-zero national health service. This project was funded for the London trusts.
Why work with us?
Our in-house consultancy team draw on experience across numerous sectors to maximise the value of Solar PV systems. We generate high-resolution energy models of the sites including all generation, storage and demand assets, and design a PV system which provides the maximum value for that specific scenario. In addition to energy cost savings, we also consider resilience, energy infrastructure costs and carbon reductions.
Our Solution
We brought our experience in project management along with the installation and delivery of Solar PV projects to ensure a high-quality options assessments was delivered via this engagement.
We analysed the options to integrate renewables generation into the existing electrical network of the following sites: University Hospital Lewisham, Queen’s Hospital, King George Hospital, Royal London Hospital, Newham Hospital and West Middlesex University Hospital.
Key Outcomes
Our consultants identified the relevant design standards that would be applicable for the proposed installations and identified a value-for-money solution that prioritise the use of generated solar energy. For each NHS site, our team identified the technical and financial challenges. We achieved this by developing a financial tool that models the whole-life cost of the scheme. Our deliverables also included a comprehensive electrical design, specifying inverter and cable routing, preparation of G99 applications where required, and a detailed tender specification.
At the end of the project, for each site we develop a final report with technical and financial analysis summarising their options, financial viability, risks and benefits and resources required to deliver the project.
