The Short-Term Electricity Markets in India are operated based on the Available Transfer Capability (ATC) declared by National Load Dispatch Centre (NLDC). A realistic determination of ATC is thus necessary for optimal market operation in India. This paper discusses the various issues and challenges in the ATC calculation and the methods that can be adopted to make a more realistic estimation of ATC. In this paper a Modified Repeated Load flow Method (MRPF) is presented for calculation of Total Transfer Capability. The method is applied to the All India 3771 Bus system and the time of calculation of TTC by MRPF method is compared to the RPF method. The study is also conducted to analyze and assess the effects of loop-flows, and simultaneous power transfers between the different regions of the Indian Transmission Grid
