The efforts of Tamil Nadu Generation and Distribution Company (TANGEDCO) efforts to augment its generation during power critical situation proved "inadequate" as two projects of 3,270 MW were delayed, CAG said in its report.
"It (TANGEDCO) took up two thermal projects with capacity of 1,800 MW at North Chennai Thermal Power Project I and II (NCTPP) and Mettur Thermal Power Project (MTPP). Though these projects were slated for completion before 2011, only MTPP was completed by October 2013," the report said, adding the NCTPP was undergoing trials as of December 2013.
"Despite delays in the projects, TANGEDCO did not fix the responsibility either at its end or on the EPC contractors and allowed periodical extensions to them," it said.
Due to the delay in implementing the projects, CAG said TANGEDCO was led to purchase power from "costlier resources", it said.
CAG suggested TANGEDCO should have a plan for pre-order activities to avoid delays in project implementation and ensure that tender specifications are accurate and realistic.
