Military Bases
Reliable, efficient, and resilient onsite energy for defence and security facilities.
About Military Bases
Military installations and defence facilities require highly reliable and secure energy systems to power operations, living quarters, training centres, and mission-critical infrastructure. Bases often operate continuously, supporting communications, logistics, and strategic readiness, where any disruption to power or heat supply can impact national security and personnel welfare.
As defence organisations aim to modernise infrastructure, reduce emissions, and enhance energy independence, Combined heat and power (CHP) and trigeneration (CCHP) systems offer proven solutions. These technologies deliver high-efficiency, low-carbon energy for diverse on-base needs, including electricity, heating, and cooling.
When integrated within a microgrid, these systems provide the additional advantage of energy autonomy — enabling bases to operate independently from the grid if required. This combination of efficiency and resilience strengthens operational capability and supports long-term sustainability goals within the defence sector.
Benefits of Flexible Energy Systems for Military Facilities
• Provides reliable and secure onsite power, heat, and cooling for essential base operations.
• Improves energy efficiency and reduces fuel consumption.
• Enhances energy independence and mission readiness through grid-independent operation.
• Reduces carbon emissions and supports defence decarbonisation strategies.
• Enables integration with renewable technologies for sustainable energy resilience.
Energy Resilience and Security in Defence Operations
Energy resilience is fundamental for military facilities, where continuity of operations must be maintained under all conditions. Grid disruptions or power outages can compromise communications, data systems, and critical infrastructure.
CHP plants deliver dependable, onsite power and thermal energy while reducing reliance on external networks. When integrated as part of a microgrid, these systems can operate autonomously in island mode, ensuring continuous energy supply during grid interruptions or emergencies.
This capability enhances energy security, reduces exposure to external threats, and supports efficient use of resources across the entire installation. The result is a robust, self-reliant energy infrastructure that aligns with defence sustainability and operational priorities.

Combined Heat and Power (CHP)
CHP systems generate electricity and recover waste heat for use in space heating, hot water, and other essential base services. Delivering overall efficiencies above 80%, CHP reduces fuel consumption and emissions while providing a highly reliable, decentralised energy supply. For military facilities operating around the clock, CHP offers secure and controllable onsite generation that supports mission readiness and operational stability. It also enhances resilience by ensuring continuity of power and heat during grid interruptions, helping defence organisations maintain self-sufficiency and meet long-term energy efficiency and decarbonisation targets.
Trigeneration (CCHP)
CCHP builds upon CHP by converting recovered heat into chilled water via absorption chillers, supplying efficient cooling for command centres, IT infrastructure, and accommodation blocks. This three-in-one configuration ensures comfortable, stable environments in all conditions while minimising electricity demand for conventional chillers. By providing heating, power, and cooling from a single system, CCHP reduces energy use and carbon emissions, improving sustainability across the base. Its consistent performance and controllability make it ideal for critical defence installations that depend on continuous operation and stringent environmental control.
Microgrids
Microgrids combine onsite generation, energy storage, and intelligent control systems to deliver secure, independent energy for military facilities. They can operate in grid-connected or island mode, allowing complete autonomy if external supply is disrupted. For defence sites, microgrids enhance resilience, support flexible energy management, and integrate renewable power where available. This approach strengthens operational security, ensuring critical missions and communications remain powered under all conditions. By optimising generation and storage, microgrids also reduce fuel use, lower emissions, and contribute to the armed forces’ transition toward low-carbon, energy-secure operations.
