CEB responds to shortcomings pointed out by power regulator

Apr 20, 2016 (LBO) – Sri Lanka’s Ceylon Electricity Board (CEB) has responded to shortcomings pointed out by the Public Utilities Commission of Sri Lanka (PUCSL) after recent island-wide power failures.

In a letter dated 28th March, 2016, the CEB has agreed to the recommendations, but does not include a detailed explanation for the island-wide power failure.

The Commission earlier demanded an explanation for the three island-wide power cuts which took place in the last six months.

The PUCSL pointed out several shortcomings such as the dynamic transmission system model used by CEB transmission planning and system control branches is not accurate enough for dynamic response analysis, the model data needs to be verified with field tests for system elements along with accurate modeling of loads according to a study conducted investigating the power failures.

“It is the responsibility of the Transmission Licensee (CEB) under Condition 30 of the Transmission Licence to maintain an uninterrupted power supply throughout the country, which has been violated three times in the last 6 months by way of island wide power failures,” the PUCSL said in the letter to CEB.
