HydroelectricHydroelectricity has played a very significant role in the national installed power capacity since. ECONOMYNEXT – Sri Lanka’s state-run Ceylon Electricity Board said it has begun seeking funds to build a 600 MegaWatt pumped storage plant to integrate solar and wind energy and maintain grid stability. The CEB wanted to tap multilateral lenders to reduce electricity sales prices. [pdf]
The Ceylon Electricity Board (CEB) has issued an international competitive bidding tender for the development of 160 MW/640 MWh standalone Battery Energy Storage Systems (BESS). Bids must be submitted by September 10, 2025. Bids will be opened on the same day. [pdf]
In 2024, lithium battery prices in Sri Lanka for solar systems range from LKR 500,000 to LKR 1,400,000 (1,600−1,600− 4,500), while EV batteries range from LKR 2,000,000 to LKR 6,000,000 (6,400−6,400− 19,200). [pdf]
Evaluate Capacity and Depth of Discharge (DoD): Choose a battery that fits your energy consumption, paying attention to its DoD—lithium-ion batteries allow deeper discharges (up to 90%) compared to lead-acid (around 50%). [pdf]
