Microgrids
Resilient, decentralised energy systems that deliver reliable, flexible and low-carbon power.
What is a Microgrid?
Microgrids are decentralised energy networks that can integrate multiple sources—such as gas engines, solar photovoltaic (PV) arrays, wind turbines, battery energy storage (BESS), and advanced control systems—to deliver reliable and efficient local power.
They can operate in parallel with the local electricity grid or independently in island mode, making them ideal for both critical infrastructure and remote locations. Microgrids reduce dependency on the grid, improve energy security, and optimise the use of low-carbon and renewable energy sources.
These systems are increasingly adopted in industrial, utility, data centre and commercial settings to support decarbonisation, enhance resilience, and unlock new value streams through smart energy management and grid interaction.

Frequently Asked Questions about Microgrids
Technical and Engineering
What is a microgrid and how does it function in energy systems?
A microgrid is a decentralised, self-contained energy system that can combine multiple generation sources—such as solar, wind, gas engines, and battery storage—with load management and smart controls. It can operate in parallel with the national grid or independently in “island mode” to provide local energy security.
How does a microgrid enhance energy resilience during outages?
Microgrids are designed to disconnect from the main grid in the event of failures or disturbances. During outages, they continue to supply power to critical loads using local generation and storage, maintaining operations in hospitals, data centres, industrial plants, or remote areas.
How do microgrids manage and optimise renewable energy sources?
Advanced microgrid control systems use real-time data to balance intermittent renewable inputs like solar and wind with dispatchable sources such as gas engines. Energy storage systems smooth fluctuations, allowing the system to maximise renewable penetration while maintaining power quality.
What does “island mode” mean in microgrid operation?
Island mode refers to a microgrid's ability to operate independently from the main grid. This mode is crucial for maintaining critical power supply during grid faults or in isolated areas with limited grid access. Systems must include control and protection features to ensure stable, standalone operation.
Financial and Commercial
How do microgrids reduce energy costs for businesses or communities?
Microgrids help users lower costs by generating power on-site, reducing reliance on grid energy during peak price periods. Intelligent load management, energy arbitrage, and demand forecasting further optimise consumption and improve economic returns.
Are financial incentives or funding available for microgrid projects?
Many governments and energy regulators offer funding schemes, tax credits, or feed-in tariffs to support the adoption of microgrids, especially those integrating renewables or improving grid resilience. Clarke Energy can assist in identifying relevant local incentives during project development.
Can microgrids generate additional revenue through grid services?
Yes, microgrids can participate in demand-side response programmes or provide ancillary services such as frequency regulation, capacity support, and voltage control. These activities help stabilise the grid while offering financial returns to microgrid owners.
Environmental and Sustainability
How do microgrids contribute to decarbonisation and lower emissions?
Microgrids reduce emissions by maximising the use of clean, renewable energy and optimising system efficiency. By generating electricity closer to the point of use, they also avoid transmission losses associated with centralised grids.
Can a microgrid run entirely on renewable energy sources?
Yes, microgrids can operate using 100% renewables if properly designed with sufficient generation capacity and energy storage. Hybrid microgrids often include gas engines for backup or dispatchable power when renewable input is low.
Are microgrids aligned with corporate and national net-zero goals?
Absolutely. Microgrids support the transition to low-carbon energy systems by integrating renewables, improving efficiency, and enhancing energy autonomy. They’re a strategic asset for organisations committed to decarbonisation and energy resilience.
Operational and Implementation
What is the typical timeline for implementing a microgrid project?
Implementation times can vary depending on the system’s complexity, permitting, and site conditions. A standard microgrid project may take between 6 to 18 months from feasibility assessment to commissioning.
What types of operational support are provided for microgrids?
Clarke Energy provides end-to-end support, including system design, installation, commissioning, remote monitoring (e.g. via myPlant®), and full operation and maintenance (O&M) services. This ensures long-term performance and system availability.
Can a microgrid be scaled or upgraded after initial installation?
Yes, microgrids are modular by nature. They can be expanded to incorporate additional generation, storage, or load as energy demand grows or new technologies become viable, allowing future-proof flexibility.
