The Public Utilities Commission of Sri Lanka (PUCSL) has granted approval to impose one-hour power cuts across four zones from today (19), if the National System Operator (NSO) is compelled to introduce demand management measures due to insufficient electricity generation following the unavailability of the Lakvijaya Power Station.
The proposed interruptions are scheduled to take place during the evening peak-demand period, between 4.30 p.m. and 8.30 p.m., over three days.
The NSO had sought approval from both the PUCSL and the Ministry of Energy to implement the restrictions, citing the need to manage electricity demand if available generation capacity proves insufficient to meet requirements.
The approval allows the NSO to introduce interruptions, if necessary, rather than indicating that power cuts will inevitably occur throughout the three-day period.
Lakvijaya outage raises supply concerns
The unavailability of the Lakvijaya Coal Power Station has raised concerns over the country’s ability to meet electricity demand, particularly during the evening peak, when consumption typically increases.
The power station, located in Norochcholai, is a major contributor to Sri Lanka’s electricity supply. Any reduction in its generation capacity can place additional pressure on the national grid, particularly when demand is high.
Demand management measures, including scheduled power interruptions, may be required if the electricity available from other sources is insufficient to maintain an uninterrupted supply.
Four zones face possible interruptions
Under the approved arrangement, electricity supply interruptions may be implemented across four groups during the evening peak-demand window, from 4.30 p.m. to 8.30 p.m.
Each affected group would face a one-hour interruption, subject to the NSO’s assessment of the electricity supply situation and the need to manage demand.
The specific areas falling within the four groups and their respective interruption times have not been detailed in the information provided.
The proposed measures are intended to help balance electricity demand with available generation capacity and maintain the stability of the national power system.
The NSO is responsible for coordinating electricity generation and supply across the national grid, while the PUCSL regulates the electricity sector and oversees matters relating to the reliability and continuity of supply.
