Frequently Asked Questions

Valuable answers to common questions about greenhouse generators and combined heat and power (CHP). See our list below.

The application can be installed in greenhouses of any size. However, a greenhouse of 10 acres or more will have better returns on the investment.

There are numerous programs at local and federal levels from which the CHP greenhouse application could get benefited. DSIRE is the most comprehensive source of information on incentives and policies that support renewables and energy efficiency in the United States.

When greenhouse growers explore the opportunity of implementing cogeneration facilities at their operations, negotiating favorable, long-term electricity and natural gas contracts with utility companies could be a possibility. Cogeneration could make greenhouse operations more competitive. 

Other benefits of cogeneration include producing electricity in communities where it is needed, thereby avoiding or deferring investments in transmission and distribution network infrastructure, and displacing higher-cost generation plants. Cogeneration also reduces losses of electricity that inevitably occur during transmission from a large central power station, which are estimated to be around 9–10 percent of net generation. 

Cummins has been installing greenhouse applications for more than 10 years. 

Cummins provides comprehensive, turnkey CHP system management — from sizing, design and installation to ongoing operation and maintenance. Greenhouse growers can realize the full benefits of CHP simply by letting the experts at Cummins handle all the details.

For greenhouse growers who choose to own the CHP system, Cummins also provides them with the expertise to design, install and maintain the system. This approach enables the grower to benefit from ongoing energy savings, increased yields and additional profits where there’s an opportunity to sell surplus energy back to the utility. The operation and maintenance contract allows the grower to focus on the operation of the core business: growing the crops.
