Sri Lankan businesses have until November 5 to submit objections and observations on the proposed fourth-quarter electricity tariff revision, following the opening of a public consultation by the Public Utilities Commission of Sri Lanka.
The consultation began on October 16, more than two weeks after the quarter under review had already started.
According to the regulator, the National System Operator submitted its bulk supply cost proposal on October 7. The Commission subsequently began reviewing the submission under the Sri Lanka Electricity Act.
The proposed review concerns electricity tariffs for October through December 2026.
For businesses, the timing means that the regulatory process is taking place during the period for which electricity charges are being assessed.
Consultation opened after the quarter began
The fourth quarter started on October 1. The National System Operator submitted its cost proposal six days later, on October 7.
PUCSL opened the public consultation on October 16, giving stakeholders until November 5 to provide written comments.
Calculations based on the regulator’s published dates show that the consultation opened 15 days after the quarter began. Its closing date falls 36 days after the beginning of the period under review.
1 October: Fourth quarter begins.
7 October: National System Operator submits its bulk supply cost proposal.
16 October: PUCSL opens public consultation.
5 November: Deadline for written submissions.
The regulator has indicated that details of oral consultation sessions will be announced separately.
A final decision has not been published in the consultation notice.
What the review means for companies
Electricity costs affect manufacturing, food processing, cold storage, hotels and other businesses that depend on continuous power supplies.
For larger industrial users, electricity expenditure can influence production costs and pricing decisions, particularly where machinery operates for extended periods or refrigeration must be maintained continuously.
Tariff changes can also affect the cost of running hotels, commercial buildings and other businesses that rely on air conditioning, lighting and electrical equipment.
The financial effect on an individual business will depend on its approved tariff category, consumption pattern and the rates eventually determined by PUCSL.
The consultation notice confirms that the regulator is reviewing the National System Operator’s submission. It does not itself establish the final percentage change applicable to any consumer category.
Nationwide blackout adds another concern
The tariff consultation opened one day before Sri Lanka experienced an islandwide electricity failure on October 17.
The National System Operator reported a total system failure following instability in the electricity system. Electricity supplies were subsequently restored in stages.
The operator also requested that rooftop solar photovoltaic system owners disconnect their systems during restoration work.
For businesses, the incident raises a separate issue from the price of electricity: the reliability of supply.
Factories, supermarkets, restaurants and hotels can incur additional costs when electricity is interrupted. The extent of those costs depends on the duration of the interruption, the availability of backup generation and the type of business affected.
No verified nationwide estimate of commercial losses from the October 17 blackout has been established in the official material examined for this report.
The technical cause of the system failure must also be distinguished from the circumstances surrounding the tariff review.
Renewable generation and system stability
Sri Lanka has continued adding renewable generation capacity, including solar installations connected to the national electricity network.
In September, Lakbima News reported on the commissioning of the 5 MW Diyajanani floating solar project at Ibbankatuwa.
As generation sources change, the National System Operator is responsible for coordinating electricity supply and demand and maintaining grid stability.
The October 17 incident provides an immediate reason to examine the system’s operating requirements. It does not establish that renewable generation caused the failure.
Businesses can submit written observations
PUCSL has invited stakeholder comments under the provisions of the Sri Lanka Electricity Act and the Public Utilities Commission of Sri Lanka Act.
Submissions may be made by email, fax or post before the November 5 deadline.
The Commission has published the consultation document and related communications on its official website.
For businesses preparing submissions, the published cost forecasts and proposed tariff calculations provide the basis for examining the financial assumptions being considered by the regulator.
The Commission’s final determination will establish the electricity charges applicable under the review.
