Delta 1.5MW/1.5MWh energy storage system installed at the Changbin Solar PV Power Plant has completed and is officially handed to the Industrial Technology Research Institute (ITRI) for commissioning. This is Delta's fourth megawatt (MW) energy storage system in Taiwan. Employing the brand-new outdoor battery cabinets and power conditioning system (PCS), the system can regulate Changbin Plant's solar power output and eliminate renewable energy's intermittent fluctuations, enabling electricity to enter the grid stably. This project is a one-stop energy storage solution, helping the client in creating the most cost-effective and applicable system configuration right from the initial stage of construction (including professional design, planning, simulation and prediction), with also the assistance of Delta’s independently developed and manufactured PCS, battery system, and energy management and control system. They greatly reduced the difficulty of system integration and shortened the test time. Among all contract energy storage manufacturers in the Changbin Solar PV Power Plant, Delta is the first to pass ITRI’s delivery test and has its system connected to the grid.

"It was a great honor to be able to participate in ITRI's Regional Energy Storage Demonstration and Verification Program commissioned by the Energy Bureau of the Ministry of Economic Affairs. Under the guidance of energy transition policies and led by industries, electrical energy will become the next generation tech industry. The rising proportion of renewable energy generation, returning of Taiwanese businesses to build new factories in Taiwan, increase of investment by the semiconductor industry, and the significant power demand driven by electric vehicles, will all bring challenges to the grid. Delta is an energy storage solution provider complete with independent R&D, local manufacturing, and technical support. It also actively works with industry partners to accrue experience in energy storage," stated JJ Chang, General Manager of EISBG at Delta.

Delta adopted the brand-new outdoor battery cabinets and the megawatt outdoor power conditioning system PCS2000 for the Changbin Plant. Unlike the traditional container, this open design saved space by eliminating the container walls and passageway inside the container, and concentrating all battery cabinets in the same area size to effectively boost the energy density. A lithium-ion battery system with up to 4,000 kilowatt-hours can be configured in a standard 40-foot container, which is three to four times that of a traditional enclosed container. Delta is capable of independent development, while maintaining the flexibility of customization and third-party integration. For example, the battery management system allows integration of different types of batteries to accommodate divergent energy storage applications; the DeltaGrid® EM energy management system can operate independently or interface with the system on-site. With a complete and diversified solution portfolio, Delta can meet the customization requirements of local power grids.
