Update, Saturday 24 October: the reconnection is confirmed as done
Friday’s reporting described a schedule. A second newsroom has now confirmed the outcome.
All three generating units at the Norochcholai Lakvijaya coal power plant have been successfully reconnected to the national grid, Hiru News reported on Saturday afternoon, describing the step as completed rather than planned.
The distinction matters. The article below was written from an NSO statement setting out when Units 03 and 01 were due back — Friday morning and Friday afternoon respectively. A plant reconnection timetable is a forecast, and this plant has already shown this month that its units can come off the system without notice. Saturday’s filing closes that gap: the plant is whole again, and the 810MW it contributes is back on the system in fact, not in prospect.
Hiru’s account of the cause matches the record in this article exactly. The island-wide failure of 17 October was caused by an imbalance in the transmission system that tripped all three Lakvijaya units; a three-day island-wide power cut followed; and the restoration of the second generator on 20 October was what ended the cuts. That is an independent confirmation of the sequence, from a newsroom that was not the source for it.
The last two generating units at the Norochcholai Lakvijaya coal power plant were due back on the national grid on Friday, completing the plant’s recovery from the island-wide blackout of 17 October.
The National System Operator (NSO) said Unit 03 was scheduled to be reconnected on Friday morning, with Unit 01 to follow by the afternoon, NewsFirst reported.
With all units back, the total capacity the plant contributes to the national grid is 810 megawatts.
How the outage unfolded
A nationwide power failure struck at 11:43 a.m. on Saturday 17 October, caused by an imbalance in the transmission system. All three generating units at Lakvijaya tripped as a result.
With the country’s largest plant off the system, the NSO divided the island into four zones for rotational demand management — the schedules that governed power cuts over the following days.
The operator said on Thursday that daily demand management was no longer required, after the plant’s second unit returned to its full 270MW output. Friday’s reconnections restore the remaining headroom rather than ending the cuts, which had already been lifted.
Context
Norochcholai is the single largest generating asset on the Sri Lankan system, and the sequence of this month’s outage illustrates why: the loss of one plant was enough to require island-wide rationing for close to a week.
At the time of writing, NewsFirst was the only verified newsroom this desk found carrying the reconnection timetable for Units 03 and 01; neither the Daily Mirror’s breaking-news listing nor Hiru’s homepage had filed on it.
