Electricity tariff revisions for the second and third quarters of this year are scheduled to come into effect from today (11).

The Public Utilities Commission of Sri Lanka had recently granted approval to implement the electricity tariff revision for the second quarter of 2026 with effect from 1 April.

Under the approved revision, electricity tariffs were increased by between 8% and 14.4%.

Against this backdrop, the National System Operator had once again submitted a revised electricity cost estimate to the PUCSL on 27 April, seeking a further increase in electricity tariffs for the second quarter of this year.

The request had reportedly been made citing the rising cost of electricity generation due to increased fuel prices.

However, the Government has provided a written assurance to the Commission agreeing to grant a Rs. 15 billion subsidy in order to prevent electricity consumers from being burdened by the latest tariff increase.

According to the revised structure, around 95% of electricity consumers in the country will not be affected by the increase.

Accordingly, no tariff increase will apply to domestic consumers using between 0 and 180 units of electricity.

However, the bill of a domestic consumer using more than 181 units — for instance 210 units — will increase by Rs. 1,760, from the current Rs. 9,570 to Rs. 11,330.

Meanwhile, the existing bill of a consumer using 240 units, which currently stands at Rs. 12,120, has been increased by Rs. 2,210, bringing the new bill to Rs. 14,330.

The electricity bill for domestic consumers using 270 units is expected to increase by Rs. 2,660, while consumers using 300 units will see their monthly bill rise by Rs. 3,110.
