Electricity tariff fluctuations could be brought to an end if Sri Lanka takes steps to reduce power generation from thermal sources, the Chairman of the Public Utilities Commission of Sri Lanka (PUCSL) K. P. L. Chandralal has stated.

Speaking at a media briefing held today (24) on the purchase of electricity from power plants based on different energy sources, Chandralal said the cost of generating electricity through thermal power had been a major factor behind fluctuations in electricity tariffs in recent years.

He said Sri Lanka should make greater use of solar and other renewable energy sources where such generation capacity is available, rather than continuing to rely on thermal power.

According to the PUCSL Chairman, generating electricity using thermal sources also results in unnecessary foreign exchange outflows, as fuel required for power generation has to be imported.

He further noted that changes in global oil prices can affect fuel costs and, consequently, the costs associated with electricity generation. Such fluctuations can ultimately have an impact on electricity tariffs.

Chandralal therefore stressed the importance of reducing dependence on thermal power and increasing the contribution of renewable energy to Sri Lanka's electricity generation mix.

Sri Lanka's electricity tariffs have undergone several revisions in recent years. In June 2025, the PUCSL approved a 15% electricity tariff increase, while a further tariff revision was approved in March 2026, with increases varying according to consumer category and level of electricity consumption.
