Hybrid Energy Management System (hEMS)

A hybrid energy system combines two or more power sources usually generators plus battery storage under one intelligent controller. It stores surplus energy and releases it on demand so engines run fewer hours at their most productive load, cutting fuel use and emissions.

A standard setup runs multiple gensets at partial load to cover demand swings, which wastes fuel and increases wear. A hybrid power system adds battery storage and smart controls, so generators run at their best load point and stored power covers the peaks.

The software reads power demand at the millisecond level, dispatches battery output in real time, and uses machine learning to tune each site over time. It also feeds predictive maintenance and gives operators one dashboard for fuel, runtime, and emissions data.

No. The hEMS layers battery storage and controls onto existing gensets rather than replacing them, which is why deployment is fast and low-disruption.

CleanDesign is a Canadian hybrid energy management company deploying the hEMS across oil and gas, mining, and remote operations in Canada and North America, with 22 units deployed as of 2024.

On deployed CleanDesign hybrid rigs, diesel consumption has fallen by up to 48%, with fuel savings around $300,000 per rig per year. Actual savings depend on site load profile.
