Keeping Data Alive
Resilient, efficient, and sustainable power systems for mission-critical infrastructure.
Decentralised energy solutions for data centers
Data centres are the backbone of the digital economy—supporting, artificial intelligence (AI), cloud platforms, enterprise applications, and global connectivity. These facilities demand uninterrupted power, advanced cooling, and the flexibility to scale with rising digital workloads.
Energy systems must now do more than provide backup. They must deliver high availability, enable decarbonisation, and support long-term operational efficiency. Operators are under pressure to secure reliable, low-carbon power while managing costs and aligning with ESG objectives.
Clarke Energy enables this transition with intelligent, scalable infrastructure that works on- or off-grid. Our solutions support grid resilience, renewable integration, and revenue generation through energy market participation—turning power systems into strategic assets.

Smarter energy economics
Clarke Energy’s solutions reduce exposure to grid failures and volatile energy markets, delivering both financial and environmental gains. By combining decentralised generation with energy recovery, data centres can achieve long-term cost savings while advancing their net-zero strategies.
CCHP and hybrid systems lower utility bills and reduce emissions. Operators can monetise excess heat or power, participate in grid services, and future-proof their facilities against changing regulatory demands. These assets become more than infrastructure—they become part of a dynamic, revenue-generating energy ecosystem.

Data centres come in a variety of forms, each with distinct energy demands and operational characteristics. Clarke Energy delivers tailored solutions across the spectrum:
Hyperscale and Co-location Data Centres
Hyperscale AI and High-Density Compute Facilities
Enterprise Data Centres
Edge Data Centres
Hyperscale and Co-location Data Centres
• Power requirements typically range from 50MW to over 1,000MW, often exceeding the capabilities of local grid infrastructure.
• Gas-fired power generation provides a rapid and dependable alternative, with high efficiency and resilience.
• Ideal for grid-constrained sites or when speed to market is critical.
Hyperscale AI and High-Density Compute Facilities
• Characterised by volatile load profiles due to fluctuating AI and GPU-driven processing.
• Hybrid systems combining gas engines with battery energy storage systems (BESS) help buffer load swings and reduce reliance on diesel.
• Integration with microgrid controllers enhances dynamic load management and optimises energy economics.
Enterprise Data Centres
• Typically sized between 1–10MW, often located near office campuses.
• Combined Heat and Power (CHP) systems offer dual benefits: reliable electricity and usable thermal energy for heating, cooling or absorption chilling.
• Supports corporate sustainability goals and Scope 1/2 emissions reductions.
Edge Data Centres
• Distributed facilities located near end users to reduce latency and improve performance.
• Onsite energy solutions such as modular gas power or CHP enhance resilience, especially in power-constrained urban areas or where grid upgrades are unfeasible.
• Scalable to support future chip upgrades and AI-enabled edge applications.
