Sri Lanka’s Energy Transition: Progress, Emerging Risks, and Pathways to Sustainability

Abstract

Sri Lanka's energy sector is undergoing a significant transition, driven by rising electricity demand, continued dependence on imported fossil fuels, and ambitious renewable energy (RE) targets. Electricity generation reached approximately 17.8 TWh (17,800 GWh) in 2025, reflecting continued growth in electricity demand and generation capacity. Renewable energy sources, led by hydropower and increasingly supplemented by solar and wind power, account for a substantial share of the country's electricity generation. Sri Lanka has set a target of achieving 70% renewable electricity generation by 2030. This paper reviews current electricity consumption patterns and demand drivers, the potential and utilization of renewable energy resources, their contributions to sustainability and energy security, emerging market and investment opportunities, and key challenges, including grid stability, renewable-energy intermittency, limited energy-storage capacity, financing constraints, and policy and regulatory uncertainty. Evidence-based recommendations are provided for policymakers, investors, and other stakeholders to

support the development of a resilient, secure, and low- carbon energy future for Sri Lanka.
