Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what recent assessment his Department has made of the potential impact of installing renewable energy sources at MoD Ashchurch on i) energy cost savings and ii) carbon reduction.

The Vehicle Storage and Support Programme (VSSP) at MOD Ashchurch is delivering modern, sustainable storage solutions for the Army’s Stored Fleets. The project, on track for completion in March 2027, includes the installation of a photovoltaic (PV) array to support the energy needs of new Controlled Humidity Environment (CHE) units. These units will reduce vehicle degradation and maintenance requirements, delivering long-term cost savings and improved operational readiness.

While the CHE units will increase electricity usage, the PV array—anticipated to produce 1,542,499 kWh annually—will meet 60% of this additional demand. This will reduce reliance on external electricity, enhance energy resilience, and avoid 427,735 kg of CO2 emissions per year.

Furthermore, all new buildings that are part of the VSSP will incorporate energy-efficient systems, including heat recovery, air source heat pumps, and advanced lighting, reducing fossil fuel use and cutting carbon emissions by a third. These measures will ensure that the increased energy usage is offset by significant cost savings, improved efficiency, and a reduced carbon footprint, supporting the Department’s sustainability objectives.
