The EV Charging Power Challenge
The electrification of transport is accelerating across public charging networks, fleet depots, logistics hubs, and commercial sites. Fast and ultra‑fast EV chargers introduce high, intermittent electrical loads, often concentrated in short time windows, placing significant strain on local grid infrastructure.
In many locations, grid capacity is constrained. Operators face lengthy connection delays, costly upgrades, and exposure to high peak demand charges. At the same time, EV users increasingly expect chargers to be reliable and always available - making outages or curtailment unacceptable for critical transport operations.
As transport electrification becomes central to decarbonisation strategies, EV charging sites require power systems that are firm, dispatchable, and flexible, capable of working alongside renewables while maintaining performance, reliability, and commercial viability.
Use Cases & Applications
Public Fast Charging Hubs & Highway Corridors
Fleet Depots – Logistics, Buses, Municipal Fleets
Retail, Commercial & Business Parks
Industrial Sites Adding EV Charging
Public Fast‑Charging Hubs & Highway Corridors
High‑power chargers create intense, short‑duration demand spikes. Clarke Energy’s microgrids provide dispatchable power and fast BESS response, helping operators deploy ultra‑fast chargers without waiting for major grid reinforcement.
Fleet Depots – Logistics, Buses, Municipal Fleets
Predictable charging windows combined with operational criticality make resilience essential. Gas engine microgrids ensure fleets can charge reliably overnight or during peak operations, even during grid outages.
Retail, Commercial & Business Parks
EV charging attracts customers and tenants but can trigger high demand charges. Integrated BESS and generation help manage peaks while maintaining a positive user experience.
Industrial Sites Adding EV Charging
Where EV charging supports logistics or workforce transport, Clarke Energy’s solutions allow sites to expand charging capacity without disrupting core operations or exceeding grid limits.
Our Gas Engine Microgrid Solution
Clarke Energy designs and delivers gas engine‑based microgrids specifically engineered to support high‑power EV charging applications. These systems integrate multiple technologies into a coordinated energy platform:
At the core are INNIO Jenbacher gas engines, providing dispatchable, flexible generation that can respond dynamically to EV charging demand. These engines operate efficiently across a wide load range and can be configured to support island‑mode operation during grid outages.
A Battery Energy Storage System (BESS) is integrated to deliver fast response power, smoothing rapid load changes from fast chargers, supporting peak shaving, and enabling energy optimisation.
The system is coordinated by advanced microgrid controls, which intelligently manage the interaction between:
- Gas engines
- BESS
- Local grid import/export
- Optional onsite renewables such as solar PV
This control layer ensures power quality, balances loads, and optimises dispatch in real time.
Multiplier generation in action
By combining gas engines, BESS, and smart control—not relying on a single technology—Clarke Energy’s microgrids deliver “multiplier generation”: greater flexibility, resilience, and overall value per unit of installed generation capacity. The system responds faster, uses assets more efficiently, and adapts as site requirements evolve.
