Evaluating CHP management and outputs using simple operational data

Abstract

Combined Heat and Power (CHP) systems can satisfy thermal and electrical demand within cities. But, operating CHP outside of optimal conditions can result in performance below the predicted level. This study uses a 6-year dataset collected by a Local Authority (LA) from a CHP-led heat network. The results show, the studied CHP electrical output fell by around 30% and was not quickly rectified. This resulted in an estimated loss of revenue for the LA of £18 500. The paper highlights the importance of a simple method to review key operational data from a CHP-led system and ensure consistent management and output.
