Cogeneration

Reliable on-site power that raises your system efficiency from 50% to 80% and reduces your energy production cost by an average of 50%.

How it works

Electricity and heat from one fuel source

Natural gas drives a generator, which produces electricity. Cogeneration happens when you capture and reuse the generator’s exhaust heat for heating and cooling needs: space heating, hot water, pools and spas, steam, and absorption cooling.

  • Cogeneration electricity costs less than utility power
  • Cogeneration technology is up to 90% efficient
  • Units can be stacked, from 200 kW to 1 MW and beyond, and run only as many as you need
  • With SeamlessPowr™, your facility is protected against utility power failures

Efficiency

Why one fuel beats two

Most facilities get power from two sources: electricity from the utility, and natural gas burned in boilers for hot water. Cogeneration equipment makes hot water nearly as efficiently as a boiler, and produces an equal amount of energy as electricity at the same time.

Conventional: utility power plus an on-site boiler

Two fuel sources, one for electricity and one for heat.

Cogeneration

One fuel source produces both electricity and usable heat.

Built for daily operation

A single 200 kW module is about the size of a large double refrigerator and fits in the footprint of one parking space. It runs about as loud as a dishwasher, and can be housed in a sound-attenuated enclosure to meet local permit limits. Suppliers typically include a 10-year maintenance warranty covering scheduled and unscheduled service, with remote monitoring.
