The National Renewable Energy Laboratory (NREL) publishes benchmark reports that disaggregate photovoltaic (PV) and energy storage (battery) system installation costs to inform SETO’s R&D investment decisions. This year, we introduce a new PV and storage cost modeling approach. [pdf]
[FAQS about PV energy storage investment cost]
According to the Long Term Generation Expansion Plan 2023-2042 Sri Lanka should have 300 MW/ 1700+MWh of battery storage by end of 2025. But instead of working on recommendations they are looking at disconnecting rooftop solar panels and halt rooftop solar panels that would be installed in future. [pdf]
[FAQS about Sri Lanka PV Energy Storage Policy]
Large batteries can store energy when production is high and release it when demand soars, ensuring a consistent power supply. Innovations like lithium-ion batteries and pumped hydro storage are proving critical in balancing the supply and demand of renewable energy. [pdf]
[FAQS about Energy storage plus photovoltaic new energy]
A solar plus storage system combines solar panels for electricity generation with battery energy storage, allowing excess energy to be stored for later use. This setup ensures greater energy independence and grid resilience. Without storage, most solar power systems shut down during grid outages. [pdf]

Cambodian natural mineral water producer Kulara Water has commissioned France’s TotalEnergies to design, install and operate a solar array coupled with on-site energy storage for its bottling facility in Siem Reap Province. Site of Kulara Water where the solar and storage systems are installed. [pdf]
[FAQS about Cambodia Solar Energy Plus Energy Storage Plant]
Elisa is transforming the backup batteries in its mobile network base stations into a smartly controlled, distributed virtual power plant with a capacity of 150 MWh, which serves as part of the grid balancing reserve for the Finnish electricity grid. [pdf]
[FAQS about Finland energy storage container power station solution]
Cambodia’s Ministry of Mines and Energy has published a document outlining principles to permit the use of rooftop PV. The new policy replaces a monthly capacity fee for rooftop systems, with a tariff calculated based on an intricate formula. Image: Clean Energy Economy Minnesota [pdf]
[FAQS about Phnom Penh PV Energy Storage Policy]
In March 2025, the Commission launched the European Energy Storage Inventory, a real-time dashboard that displays energy storage levels across different European countries. It is the first European-level tool of its kind and offers energy storage data across a full range of technologies. [pdf]
[FAQS about Energy storage product inventory]
A pilot project in Bern, Switzerland will aim to store waste heat from a waste incineration plant underground. This stored heat can then be used in extracted in the winter. The project aims to create an energy reserve of 12 to 15 GWh, enough to heat around 1200 to 1500 large apartments. [pdf]
