A techno-economic and environmental cost benefit analysis and assessment for the proposed 160 MW (Solar-120 MW and Wind-40 MW) hybrid renewable energy project with grid integration is carried out for electricity generation at Ramagiri & Muthavakuntla village locations of Anathapuram district in Andhra Pradesh state of India. Manual estimations are carried out based on recent research publications in similar line of studies and simulation studies are carried out using System Advisory Model (SAM) software under individual and hybrid operating modes with authenticated data resources to determine annual energy yield as well as sizing along with their economic and environmental concerns for solar and wind energy resources. Finally, comprehensive annual energy benefits are presented that shows techno-economic-environmental viability of this proposed project at the aforementioned location. © Published under licence by IOP Publishing Ltd.
