Low rainfall threatens power tariff hikes, warns Sri Lankan lawmaker

Member of Parliament D.V. Chanaka has cautioned that inadequate rainfall could necessitate higher electricity charges for consumers across Sri Lanka. The MP's statement underscores growing concerns about the country's reliance on hydroelectric generation amid unpredictable weather patterns.

Sri Lanka's electricity generation has historically depended heavily on hydropower facilities, which require sufficient water levels to maintain productive capacity. When monsoon rains fall below expected levels, reservoir levels decline, reducing the volume of electricity that can be generated through water-based plants.

To compensate for lower hydropower output during dry periods, authorities typically increase thermal power generation, which relies on imported fossil fuels. This operational shift substantially raises production costs for the nation's power utility, pressures that are often transferred to consumers through tariff adjustments.

The warning comes as the country grapples with broader energy security challenges and the need to balance infrastructure development with affordability concerns. Water resource management and renewable energy diversification have become increasingly critical issues for policymakers seeking to stabilize the electricity supply and pricing structure.
