Abstract: Energy integration using pinch technology in a Total Site (TS) has been widely used for optimization and energy saving. In this paper, wind and solar energy are integrated into a TS system using pinch concepts to reduce environmental pollution. A new procedure of Total Site Heat Storage Cascade (TS-HSC) construction is proposed, which is shorter than the current method. A strategy for estimating wind power economy in different wind turbine capacities is also presented, which includes parameters of Feed-in tariff (FiT) rate and Levelized Cost of Electricity (LCOE). A TS case study with energy supply/demand variations is considered to illustrate the proposed procedures. In the case study, a central solar heating plant with daily/seasonal storage and different solar thermal collector areas is used to compare the external hot utility requirements. The results showed that by increasing the area from 100 to 700 m2, the heating requirement reduction with daily/seasonal storage changes from 37.89% to 94.27%. Also, by increasing the wind turbine capacity from 1.5 to 2 MW, the reduction percentage of power grid usage changes from 54.23% to 79.97% and using a 2 MW wind turbine is more cost-effective than other wind turbine capacities with a 32.21% reduction in costs.
