Commercial-scale battery energy storage systems being installed at 16 electricity transmission substations across Sri Lanka are expected to be connected to the national grid in early September.
The systems, which were brought into Sri Lanka through the Colombo Port in three stages during May and June, are currently in the final stages of construction.
The project being implemented by WindForce PLC near the Anuradhapura substation is now around 85% complete.
The battery systems will store excess electricity generated by solar power plants during the daytime and release the stored electricity to the national grid at night when required.
Officials said the system would help maintain the stability of the national grid while reducing the need to generate electricity from diesel power plants during nighttime hours.
Each battery energy storage project will have a capacity of 10 MW. The National System Operator Ltd. (NSO), operating under the Ministry of Energy, will be responsible for managing and controlling the systems, while their maintenance will be handled by the respective companies.
