"NTPC Ltd signed supplementary power purchase agreement with Assam Power Distribution Company Ltd (APDCL) for supply of 75 MW power," the New Delhi-based power major said in a statement.
The power will be supplied to Assam from NTPC's Farakka Super Thermal Power Station Stage-III, it added.
The release, however, did not mention the financial implication of this sale.
At present, APDCL is allocated 190 MW power from unallocated capacity of NTPC stations Farakka Stage-I, II and III, Kahalgaon Stage-I and II and Talcher Stage-I.
The agreement was signed by NTPC Additional General Manager (Commercial) S K Kar and APDCL Chief General Manager (Commercial) A Baishya, the release said.
