One of the largest machine tool companies in the world, Ingersoll Milling Machine Company, installed a cogeneration facility and saved over 30% on their energy costs the first year of operation. This system consists of five 650 kW Caterpillar natural gas fired engines with heat recovery steam. The total system can produce 4.9 MW of electricity and 15,000 lbs./hr of low-pressure steam. Ballard Engineering was awarded an ASHRAE Energy Performance Award in 1988 for this project.

Jay Plastics is a supplier of automotive equipment in Ohio. Faced with rising electricity prices and a need to stay competitive, they decided to install a 2.4 MW power generation system. Their on site generation allows them to take advantage of real time pricing of electricity. They produce their own electricity when the purchase price is over their cost to produce it and they buy electricity from the utility when the price is less than their cost to produce it. Real time pricing is a new development in the utility industry and companies that can take advantage of it will achieve an edge over their competitors.
