Battery Energy Storage Systems vs. Gas Generators

At Baker Electric, we frequently hear questions like:

“Dear Baker – I’m seeing all this information on the internet about battery energy storage systems, but I’ve also heard that fossil fuel-based generators are a good option for me. What should I do?”

Great question! As experts in the design, application, and installation of both battery energy storage systems (BESS) and gas generators, we’re here to help you make an informed choice. Let’s dive in and explore the key differences.

What Are BESS?

BESS systems don’t generate power but store energy from sources like solar panels or the grid. They’re composed of two main components:

  • Storage System: Typically lithium-ion batteries or similar technology.
  • Inverter: Converts Direct Current (DC) into Alternating Current (AC) for use.

What Are Gas Generators?

Gas generators create electricity by burning fuel. Their key components are:

  • Prime Mover: An engine powered by diesel or natural gas, or turbines.
  • Alternator: Converts rotational energy into AC electricity.

Side-by-Side Comparison

Feature BESS Gas Generators
Initial Cost of Installation $$$ $$$
Total Cost of Ownership $$$
Battery replacement after 10-15 years may be needed.
$$
Continuous fuel, maintenance, and permitting costs over ~30 years.
Environmental Impact Low
Can use renewable energy and has zero emissions.
High
Burns fossil fuels, producing greenhouse gases.
Noise Levels Low High
Backup Power 2-4 hours (partial load) 4-8 hours (critical load, with sufficient fuel supply).
Energy Savings Yes
Helps reduce utility costs by managing peak demand.
No
Does not impact utility bills.
Safety Potential for fires if mishandled. Potential for fires and explosions due to fuel storage.
