Two CCHP (Combined Cooling Heating Power) plant layouts are proposed to supply the electricity, heat and cooling energy demands of textile industries. In the first proposed scenario, natural gas fueled internal combustion engines are integrated with a Heat Recovery Steam Generator (HRSG) and a hot water absorption chiller system to produce electricity, saturated steam and chilled water for air conditioning purposes. The second concept, a linear Fresnel solar field is integrated with the same CCHP to provide fuel economy the during sunny hours. The proposed plants were compared to a base case scenario in which electricity is imported from the grid, saturated steam is provided by a Natural Gas Steam Generator (NGSG) and chilled water is provided by electric chillers. Simulations were performed considering mass and energy conservation equations, information provided by equipment manufacturers and Typical Meteorological Year (TMY) data for three different locations. The plant economic performance was evaluated by calculating the Net Present Value (NPV), the Internal Rate of Return (IRR) and the Discounted Payback Period (DPP). As an important result, a great potential for reducing fuel consumption and CO2 emissions was identified. However, the high investment associated to Fresnel collectors coupled with low natural gas prices showed the hybrid concept as economically unfeasible. Nevertheless, it is expected that hybrid systems will have an important role in the near future once Fresnel technology costs are continuously declining and solar energy appears as a promising alternative for contributing substantially in the global energy transition to a low-carbon future.
