About Combined Heat & Power

Combined Heat and Power (CHP), also known as cogeneration, is an energy efficient technology that generates electricity and captures the heat that would otherwise be wasted to provide useful thermal energy.

CHP systems typically achieve total system efficiencies of 60-80%, compared to 50% for conventional separate heat and power production.

This calculator follows standard CHP efficiency calculation methods according to international standards.
