What is Combined Heat & Power?
Cogeneration or Combined Heat and Power is the process of generating electricity and useful heat at the same time. This process came about due to the fact that most power stations and heat engines produce excess heat that goes to waste. The cogeneration principle is a highly efficient process that takes advantage of by products that would other wise go to waste. The generation of heat and power simultaneously through combined heat and power can help reduce carbon emissions by up to 30% compared to the usual separate means of conventional generation.
What are the advantages of CHP?
- Reduce energy costs of up to 40%
- Zero cost outlay options available
- Enhanced capital allowances eligible
- Renewable obligation certificate compliant
- Renewable heat incentives
- Reduced Co2 and So2 emissions
- Helps new construction meet carbon legislation compliance
- Increases energy security
- Fuel choice security
- Legislative and new building benefits
- Part L compliance and meeting CRCEES targets
