Sri Lanka greenlights battery storage plan as the government moves to strengthen grid stability and support the rapid expansion of renewable energy, particularly solar power, amid rising electricity demand and shifting energy dynamics.
Sri Lanka greenlights battery storage plan to boost renewables
Sri Lanka greenlights battery storage plan with Cabinet approval for a large-scale rollout of Battery Energy Storage Systems (BESS), marking a significant step in modernizing the country’s power infrastructure. The initiative aims to address the growing challenges associated with integrating renewable energy into the national grid while ensuring stability during peak demand periods.
The approved plan includes the procurement of 300 MW of battery storage capacity, reflecting a strategic policy shift toward strengthening the country’s energy resilience. According to Minister Nalinda Jayatissa, the initiative is designed to complement the increasing contribution of renewable energy sources, particularly solar, which has seen rapid expansion in recent years.
The Sri Lanka greenlights battery storage plan follows a reassessment by the Public Utilities Commission of Sri Lanka, which identified that peak electricity demand is rising faster than previously forecast. As a result, the timeline for deploying battery storage solutions has been accelerated from 2032 to the 2028–2029 period under the country’s long-term power generation strategy.
A key component of the plan involves the development of 25 standalone battery energy storage systems, each with a capacity of 10 MW/40 MWh, contributing a total of 250 MW. These systems will be directly connected to the medium-voltage distribution network operated by the Ceylon Electricity Board. The decentralized nature of these installations is expected to enhance grid flexibility and provide localized energy storage support.
Under the proposed structure, these standalone units will be implemented through a Build, Own, and Operate (BOO) model, allowing private sector participation. Developers selected for the projects will manage operations over a 15-year period, ensuring sustained maintenance and performance. This model is anticipated to attract investment while reducing the financial burden on the state.
The Sri Lanka greenlights battery storage plan also includes a second component focused on integrating battery systems with existing renewable energy infrastructure. A 50 MW capacity will be developed by connecting storage systems directly to operational solar power plants. This approach is intended to enable solar producers to store excess electricity generated during the day and release it during peak demand hours, thereby improving efficiency and reducing wastage.
Procurement for this segment will be carried out through a competitive bidding process, overseen by the Renewable Energy Procurement and Operations Supervision Division of the National System Operator (Private) Limited. This entity, a successor to earlier operational frameworks under the power sector, will play a central role in coordinating project execution and ensuring compliance with technical standards.
The Sri Lanka greenlights battery storage plan comes at a time when solar power generation has already exceeded the integration thresholds outlined in the country’s 2023–2042 long-term energy plan. Officials have emphasized that without adequate storage capacity, further expansion of solar energy could lead to inefficiencies and grid instability.
Minister Jayatissa highlighted the importance of pairing renewable energy generation with storage solutions, noting that continued installation of solar panels alone would not be sufficient to meet future energy needs. By enabling energy storage across the grid, the government aims to unlock greater potential from renewable sources while maintaining system reliability.
From a broader perspective, the initiative aligns with national efforts to transition toward a more sustainable and diversified energy mix. The integration of BESS technology is expected to reduce reliance on fossil fuels, optimize energy distribution, and support long-term environmental goals.
The Sri Lanka greenlights battery storage plan is also likely to have positive implications for the Sri Lanka renewable energy sector, creating new opportunities for investment, technology transfer, and innovation. At the same time, it addresses critical challenges related to intermittency, which has been a key limitation in scaling up renewable energy adoption.
As implementation progresses, stakeholders will be closely monitoring the effectiveness of the dual approach, combining standalone storage units with on-site solar integration. If executed successfully, the plan could serve as a model for future energy infrastructure projects in Sri Lanka and the broader region.
