Experts urge caution as Unit 1 remains offline following October 17 blackout
By Ifham Nizam
The government’s rejection of allegations linking coal quality to the October 17 countrywide blackout has drawn a note of caution from power sector experts, as the continued shutdown of Generator Unit 1 at the Lakvijaya Power Plant in Norochcholai raises questions about the cause of the failure and the resilience of the country’s electricity supply.
Cabinet Spokesperson Dr. Nalinda Jayatissa has dismissed Opposition claims that substandard coal contributed to the incident, insisting that there was no connection between coal quality and the technical failure. However, experts have cautioned against drawing definitive conclusions before the technical investigations establish the precise cause of the breakdown.
Responding to journalists’ questions, Dr. Jayatissa said Unit 1 had undergone maintenance for 62 days, from July 30 to September 30, and that coal from a new shipment had been used for power generation since September 4.
“There is no link between the coal quality and this incident,” he said, referring to the use of coal from the new shipments.
However, power sector experts said statements about the cause of a major generating-unit failure should be made cautiously, particularly when the incident has been linked to a nationwide blackout.
They stressed the importance of establishing the technical facts before ruling out any potential contributing factor.
The quality of coal, the operational condition of generating equipment and the performance of associated electrical systems are distinct technical questions that require appropriate examination.
The use of coal from a new shipment, by itself, does not establish whether the fuel met the required specifications or whether coal quality played any role in the incident.
The precise cause of the Unit 1 failure, however, cannot be established from the information disclosed so far. No detailed technical findings were cited by the Cabinet Spokesperson to substantiate the categorical rejection of the coal-quality allegations.
The continued unavailability of a major generating unit also puts the spotlight on the importance of reliable baseload generation, adequate reserve capacity and transparent communication with electricity consumers during a period of supply disruption.
Asked about the financial losses resulting from the blackout, Dr. Jayatissa said the Opposition was calculating the cost and that its figures would be announced next week.
“Our job is to restore the system,” he said.
While restoring electricity generation remains an immediate priority, experts said that determining the cause of the incident and communicating the findings to the public would also be essential to maintaining confidence in the country’s power supply arrangements.
Dr. Jayatissa expressed hope that the power plant would return to normal operations from the following day, in line with assurances given by the authorities.
That assurance will be closely watched as consumers and businesses seek clarity over the stability of electricity supplies following the nationwide outage. Any prolonged interruption at Norochcholai, one of the country’s principal electricity-generating facilities, underscores the wider economic consequences that can arise when a major unit becomes unavailable.
For businesses, an unexpected interruption to electricity can disrupt production, damage time-sensitive goods, interrupt services and increase operating costs where backup generation is required.
The effects can be particularly burdensome for small and medium-sized enterprises, which may have less capacity to absorb additional expenses.
The incident has also renewed attention on the need for a clear, evidence-based account of what happened on October 17, including the sequence of technical events, the condition of the generating equipment and the measures required to prevent a recurrence.
The distinction between restoring the system and establishing accountability is important. While the immediate task is to ensure reliable electricity generation, a comprehensive technical assessment would help determine whether the failure resulted from equipment malfunction, an operational issue, a wider system disturbance or a combination of factors.
The allegations concerning coal quality should therefore be assessed against technical evidence, including relevant fuel specifications and test results, rather than political claims or official assurances alone.
As Unit 1 remains offline, the central question is no longer simply when the plant will return to normal operation, but whether the authorities can provide a technically substantiated explanation for a failure associated with a countrywide blackout.
