Division 7.2
United Kingdom
For the CHP part, the plant operator shall check the load pattern (useful heat demand) and evaluate whether the unit operates in full cogeneration mode during certain periods. If this is the case, the plant operator shall measure actual heat and electrical energy output from the cogeneration unit for this situation and during these periods. These data will allow him to determine the actual ‘power to heat ratio’ (Cactual)f1.

The power to heat ratio used to calculate the CHP electricity can be used also to calculate the CHP electrical capacity if the unit cannot be operated in a full cogeneration mode, as follows: PCHP = QCHP × C where PCHP is the CHP electrical capacity, QCHP is the CHP heat capacity and C is the power to heat ratio.
