This paper explores the optimal implementation of bio-methane fuelled combined heat and power (CHP) systems to satisfy heat and electricity demands of
commercial buildings; with the overarching goal of making cost-effective investments and decarbonizing building operations. The research work consisted in
the development of a CHP technology selection and operation (TSO) optimization model. Its results can be utilized to develop a strategy for investment in
bio-methane CHP projects for a portfolio of buildings. The TSO model enables a new approach for the selection and operation of CHP units that
encompasses whole life costing, carbon emissions as well as real-time energy prices and demands, providing a more comprehensive result than current methods.
Utilizing historic metered energy demands, projected energy prices and a portfolio of available CHP technologies, the mathematical model simultaneously
solves for an optimal CHP unit selection and operational strategy for a determined building based on a preferred objective: minimizing cost, minimizing
GHG emissions, or a mix of both. Results of this model prove that attractive cost and emissions savings are possible through the optimal selection and
operation of CHP technologies fuelled by bio-methane
