400kW BESS Paired with 400kVA Generator

We paired one of our 400kW BESS units with a client’s existing 400kVA diesel generator to optimise runtime and reduce light loading, fuel use, emissions, noise and servicing demand.

Key Outcomes

This project experienced the following results:

Reduced light loading

Generator operation optimised through BESS support

Lower carbon emissions

Cleaner operating profile

Reduced site noise

Quieter operation during lower load periods

Longer service intervals

Less strain on generator equipment

What It Powered

Equipment Powered: Commercial Infrastructure
Generator Used: Client’s existing 400kVA Generator

Project Summary

GeneRent paired one of our 400kW BESS units with a client’s existing 400kVA diesel generator to improve the efficiency of the overall power setup.

The battery system helps absorb lower-load periods that would otherwise leave the generator operating inefficiently, particularly during extended light-loading conditions.

By reducing light loading, fuel use, carbon emissions, site noise and servicing demand, the system supports both better day-to-day performance and longer equipment life.

Project Insight

A BESS can greatly improve generator efficiency even when working alongside an existing client-owned unit.
