Local sharing of cogeneration energy through individually prioritized controls for increased on-site energy utilization

The benefit of surplus energy sharing depends on the CHP capacities and the fuel type. When using biogas, larger CHP plants provided lower total primary energy consumption, in the most extreme case lowering it by 71%, compared to the conventional case. Using natural gas provided only a 6% decrease. The savings resulting from energy sharing were between 1% and 9% with biogas and between 1% and 6% using natural gas. The least amount of PE was consumed by having large CHP plants with biogas, due to the value of renewable electricity. Using natural gas, thermal tracking had the lowest PE consumption.
