The Ministry of Power and Energy Sri Lanka says components for a 20-megawatt battery storage system have been imported as part of the country’s larger energy transition plan.
This marks the beginning of Sri Lanka’s first commercial-scale:
- Battery Energy Storage System (BESS) project
The imported equipment forms part of a planned national battery storage network with a total capacity of:
- 160 megawatts
Project Details
According to the Ministry:
- Total project investment: Rs. 40 billion
- Objective: Build a more stable and renewable-based electricity system
- Remaining 140 MW worth of components are expected to arrive within the coming week
How the System Will Work
Under the first phase:
- Battery systems will be installed near major electricity substations islandwide
- Key connection points will include substations in:
- Galle
- Matara
The storage system is expected to:
- Store excess electricity produced during sunny periods
- Release stored energy during peak demand periods, especially at night
- Improve grid reliability
- Reduce dependence on fossil fuels
Why Battery Storage Matters
Battery storage becomes increasingly important as renewable energy grows because solar generation does not occur continuously.
Current solar contribution to national generation:
- Around 9.4% of total electricity production
Officials expect this percentage to rise with battery integration because storage can help:
- Reduce wasted renewable energy
- Balance fluctuations in power supply
- Support future renewable expansion
- Strengthen national energy security
The project represents a major shift toward modernizing Sri Lanka’s power system as the country seeks to increase renewable energy use while improving electricity system stability.
