“…The results showed that, in comparison to the traditional design, it allows saving more energy than the conventional system. Dragomir-Stanciu [9] proposed a solution to increase a Combined Heat and Power (CHP) plant's efficiency incorporated with Internal Combustion Engines by using the available thermal energy produced from hot water to generate electricity in an Organic Rnakine Cycle (ORC). A numerical model was applied based on two assumptions made by Mărcuş et al [10] using the lower heating value and the higher heating value of the natural gas.…”

This research investigates and evaluates the University Politehnica of Bucharest (UPB) possibilities to become an energy self-supplying by building up its own power plant and becoming an energy distributor. The campus has already been connected to the national natural gas supplying pipe and the local district heating and electrical network.A set of criteria was used to evaluate the feasibility of this project. Technical, financial, and environmental considerations were taken into account to determine the most suitable solution. The feasibility study assumed three proposals of an energy supply system considered for the university buildings / campus. Gas-fired heating plant, gas-fired Internal Combustion Engine cogeneration plant and gas fired Internal Combustion Engine for cogeneration with an Organic Rankine Cycle ORC.The details of each proposal were discussed to obtain the optimum solution. Elaborate. It was found from a financial and environmental perspective that the most feasible project is gas-fired Internal Combustion Engine cogeneration, considering profit revenue from selling / exporting power to the domestic electricity grid. And the Net Present Value was around one million euros for 15 years life.
