This book provides a methodology for developing an optimum investment strategy in the heating and combined heat and power (CHP) industry. It demonstrates how to apply mathematical models to the analysis of heat and electricity source operation from technical and economic perspectives. It also allows readers to ascertain the economic effectiveness of modernizing an existing CHP plant. The mathematical models presented are designed to recognize identity profits in continuous time so that they can be better predicted. The authors examine the operational costs of a CHP plant and the impact of factors, such as environmental costs, associated with investment in the heating and CHP sector to enable readers to select the most appropriate technologies. It presents a state-of-the-art technical and economic analysis to enhance readers’ understanding of investment in and optimization of heating and CHP, and provides practical guidance for investors’ decision-making. The book is a valuable source of information, making it ideal for financial analysts and power engineers. Thanks to its in-depth analysis of mathematical methods, it is also suitable for students and researchers with an interest in investment strategy.
