Solar for hospitals and healthcare
Hospitals are among the most demanding energy environments in the UK. With twenty-four hour operations, life-critical equipment, ambitious decarbonisation targets, and tight capital budgets, the healthcare sector has very particular requirements from a solar installer.
We work with NHS trusts, private hospitals, community health facilities, and specialist clinical providers across Wales.
Healthcare load profiles and solar contribution
Hospital electrical loads are continuous and dominated by HVAC, medical equipment, lighting, IT, lifts, and increasingly air conditioning. A large district general hospital typically consumes tens of millions of units of electricity per year, far more than even a substantial solar array could provide. Solar therefore contributes meaningfully but is part of a wider energy strategy that usually includes combined heat and power, heat networks, and demand-side management.
For smaller community hospitals and specialist clinics, solar can cover a much larger proportion of demand and is often the single most impactful renewable energy intervention available. We size every installation to the specific operational context rather than applying generic assumptions.
Decarbonising NHS energy supply
The NHS in Wales has ambitious decarbonisation targets, and on-site renewable generation is one of the few measures that delivers both verified Scope 2 reductions and immediate operational savings. Solar avoids the price volatility risk associated with grid electricity, providing trusts with budget certainty over the long term that is genuinely difficult to obtain through any other route.
We work with NHS estates teams to understand the specific decarbonisation plans for each trust, ensuring our proposals align with broader strategic objectives rather than being procured in isolation. This often reveals opportunities for combined projects spanning multiple sites.
Energy security and clinical resilience
Clinical operations require uninterrupted power, and hospitals already maintain extensive backup generator capacity. Adding battery storage paired with solar contributes to this resilience while reducing dependence on diesel fuel deliveries and the associated air quality and operational risks.
Working in active hospital environments
Hospital construction work requires exceptional discipline around noise, dust, access, and infection control. All our hospital installations are planned with the trust's estates and infection control teams, with clear protocols for daily working hours, access routes, and equipment movement. Staff are CRB/DBS checked and trained in healthcare-specific working protocols.
Frequently asked questions
How much of a hospital's electricity can solar provide?
It varies enormously with hospital size. Small community hospitals may see solar cover thirty to fifty percent of annual demand, while large district generals typically see single-digit percentage coverage that still represents substantial absolute savings.
Does solar integrate with our existing CHP and backup generators?
Yes. Modern solar inverters integrate cleanly with existing CHP plant, standby generators, and UPS systems through appropriate control hierarchies.
Can NHS trusts use Power Purchase Agreements?
Yes, several NHS trusts in Wales have procured solar through PPA structures where capital constraints prevented outright purchase. We work with established PPA providers experienced in the public sector.
What about Welsh Government decarbonisation funding?
Several funding routes have been available, particularly through Welsh Government, NHS Wales, and sector-specific programmes. We track current schemes and identify funding routes at the design stage.
Working with NHS procurement and estates
NHS procurement processes are necessarily structured to ensure best value and probity. We work routinely with framework agreements including SBS Public Sector, NEPO, ESPO, and YPO, where renewable energy and solar installation services are available for direct call-off without lengthy tender procedures. Where direct procurement is preferred, we are well placed to support trust procurement teams through OJEU-equivalent processes.
NHS estates teams typically have very clear views on technical standards, including specific requirements for fire safety, materials, structural assessment, and ongoing maintenance access. Our designs accommodate these requirements as standard, and we provide all the documentation typically needed for trust technical reviews, including detailed structural calculations, fire risk assessments, and maintenance access plans.
Working in active hospital environments
Hospital installations require strict adherence to infection control, fire safety and access protocols. All operatives complete trust-specific inductions covering ward access restrictions, emergency procedures, and key contact arrangements. We work in tightly defined zones, with access through plant areas where possible rather than clinical spaces, and material movement coordinated with trust portering teams. Roof work is sequenced to avoid air intake locations during demolition activities to prevent any contamination concerns.
Integration with combined heat and power and existing renewables
Many large hospitals already operate combined heat and power plant, sometimes alongside biomass boilers or other low-carbon technologies. Adding solar to this energy mix requires careful coordination between the new and existing generation, including appropriate import-export protection at the boundary and signal coordination between control systems. We work closely with the trust's CHP operators and energy manager to ensure the solar installation complements rather than disrupts existing arrangements.
Reporting solar contributions to the NHS Net Zero target
The NHS has a statutory commitment to deliver net zero by 2040 for emissions it directly controls, with the broader supply chain target set for 2045. On-site renewable generation contributes directly to Scope 2 emissions reduction and is one of the relatively few measures that delivers verifiable, audit-grade evidence of progress. We provide reporting data in formats compatible with NHS reporting frameworks including the Sustainable Development Assessment Tool used for board-level reporting in NHS Wales.
