Sri Lanka’s proposed battery storage tariffs have drawn early criticism from within the national grid operator, which says the rates far exceed prices already secured through competitive tenders.
The Public Utilities Commission of Sri Lanka (PUCSL) has proposed feed-in tariffs for battery energy storage, with an engineer from the National System Operator (NSO), the entity responsible for operating Sri Lanka’s power system, warning the rates run well above prices already achieved through competitive tenders.
PUCSL published its renewable energy feed-in tariff (FIT) review in July, opening a stakeholder consultation that runs through Sept. 9. The review proposes FITs for rooftop solar systems paired with battery energy storage systems (BESS), as well as for utility-scale ground-mounted and floating solar plants with BESS. The review was launched under Sri Lanka’s electricity and utility regulatory laws.
The July review is separate from a broader renewable energy tariff package PUCSL approved on Aug. 25, which took effect immediately and runs through Feb. 24, 2027. That package, covering mini-hydro, wind, biomass and general rooftop and ground-mounted solar, introduced Sri Lanka’s first dedicated battery storage rates. The more detailed, capacity- and time-of-day-specific tariffs proposed in the July review remain open for public comment.
