Generation in AC 11kv is only more efficient, more than 11kv generation we are getting commutation problems in alternator,same problem in dc generator also. so generation ac. cumming to transmission for higher KV DC Transmission is efficient, cumming to distribution ac efficient and reliable.
and india equipment designed fo 230v, 50Hz. if go with DC we get low efficiency and need to change equipment design.
