TALK STORAGE STRATEGIES

New energy storage field enters scale

On September 12, the National Development and Reform Commission and the National Energy Administration released the “ New Energy Storage Scale Development Action Plan (2025-2027)”, which clearly proposes that by 2027, new energy storage will basically achieve scale and market-oriented development, with technological innovation and equipment manufacturing capabilities remaining at the forefront globally.

Energy storage battery profit comparison

For example, the average revenue of an Electric Reliability Council of Texas (ERCOT) battery in 2023 was $182 per kilowatt per year, but the best-performing asset in the same region was closer to $300 per kilowatt per year, a 60 percent increase. 4 Similar dynamics—where there is a large spread between the best and worst performers—are observed in other grid-scale battery markets, such as the United Kingdom. 5 A variety of factors, including design choices such as battery duration and commercial strategy, can affect these outcomes.

Common topologies of energy storage power supplies

Most popular topologies in this regard include the Dual Active Bridge with Extended Phase Shift (for example in TIDA-010054) which deals with a primary voltage of 700V to 800V DC, and secondary voltage of 350V to 500V DC (single-phase-shift SPS) or 250V to 500V (extended-phase-shift EPS) for power levels up to 10 kW, Phase-shifted Full-Bridge (for example in PMP22951) which deals with a voltage of 400V down to 54V and a power level of 3kW or CLLLC Dual-Active Bridge (for example in TIDM-02002) which deals with a primary voltage range of 380–600V to a secondary voltage range of 280–450V and power levels up to 6.6kW.

Costa Rica Super Energy Storage Battery

Two 40-foot- MTU battery containers from Rolls-Royce with a total storage capacity of 4,275 kWh and an output of 1,500 kVA are used to meet peak electricity demand, increase the company’s own use of solar power, and relieve pressure on the public grid. 690 photovoltaic panels with 255kWp capacity have been installed by solar provider Swissol SA, Alajuela, Costa Rica, on covered parking spaces at Proquinal and connected to the battery containers to support the system.
