Feb.3 power cuts could have been avoided - PUCSL

The Public Utilities Commission of Sri Lanka (PUCSL) in a detailed report released yesterday said that the power failures which occured on February 3 which the Ceylon Electricity Board attributed to as being caused by load shedding, could have been ‘completely avoided.’

The PUCSL in a comprehensive report said in a special investigation report titled “Report on rotational load shedding carried out on February 3.”

“The system had enough capacity to supply the full demand during the period of load shedding,” the report says in its observations. The report, PUCSL cites was prepared following the inquiries and complaints of consumers received by PUCSL on the day of the interruption occurred and to avoid such events happening in the future.

The CEB in its report attributed the power outages experienced on February 3 due to the shortfall in demand citing that load shedding and the inability of the Ceylon Petroleum Corporation to supply fuel resulted in the power outages. The CEB in its report noted that the West Coast plant was shut down which resulted in the shortfall of power during such peak hours.

The PUCSL report however found that the West Coast power plant was only required to supply the night peak demand. With the West Coast resuming generation after 3pm, the total demand during the day could have been fully met.

In the worst case scenario, under the absence of the West Coast power plant, demand could have been met with limited shedding (approximately 105 MW maximum for a period less than 2 hours during the night peak.

The report found that the need to shed load during night peak due to the absence of West Coast power plant may have been avoided or lessened by shifting Kotmale operation to the night peak period.

However even under the shifting of Kotmale operation to the night peak period did not have any apparent impact on supplying the actual demand (Without shedding load) during the period from 1045 hrs to 1702 hrs, since adequate generation was present to meet the demand during this period.

“The unavailability of Westcoast power plant was identified in the Day-ahead forecast prepared by the CEB on February 02, 2020. Hence, if the availability of Westcoast power plant was uncertain, the Transmission Licensee had sufficient time to obtain the approval of the Commission under Condition 30 (10) of the Transmission Licence, prior to the load shedding required during night peak.”
