The CEB had to buy an additional 267.17 gigawatts in 2021 at a cost of Rs. 6.54 billion due to a considerable lack of progress in starting new generation plants, said the National Audit Office.
The plan had been to start new plants with a combined capacity of 2,032 megawatts during the past four years.
However, only 661.6 megatts could be secured out of the envisaged capacity, the result being the CEB was unable to supply electricity at a low cost, said the report.
The CEB management has highlighted that it cannot decide on its own the implementation of its long term plans to expand its generation capacity.
