In this paper performances of different combinations of integrated RE systems are analyzed and compared for various suitable locations in India for a load demand of 1.5 MW. These combinations of integration of REs are wind energy system (WES) and photovoltaic (PV) system; PV system and biomass energy system (BES); and BES and WES. Maximum annual electricity generated by integrated PV system and BES 8;672 MWh while maximum annual income from electricity export is $ 561;078 from integrated BES and WES system. Reduction in net annual greenhouse gas (GHG) emission is found highest of 8;850 tonnes of CO2 in the case of integrated BES and WES with income from the GHG reduction of $ 177;013 and total annual saving/income of $ 738;091. Equity payback period of integrated BES and WES is estimated as minimum of 2.7 years when cash flow becomes positive.

Performance analyses and cash flows of the integrated RE systems are carried out using RETScreen software tool. It is concluded from the results that integration of BES with another RE is more feasible than without BES in terms of electricity generation; electricity export income; GHG emission reduction; income from carbon trading and equity payback period.
