Driving green energy construction with the expansion of energy infrastructure

Having expanded from power sources into energy sources years ago following the energy transition trend, Delta has seen its energy storage solutions, including solar energy, electric vehicle (EV) charging infrastructure, and the DeltaGrid energy management system, spread and made available across North America, Europe, Japan, and Taiwan. As the first company in Taiwan to invest in the R&D and manufacturing of energy storage applications, Delta completed Taipower's first demonstration system in 2017. Not long ago, Delta announced its official participation in Taipower's Energy Trading Platform following the installation of a 5MW energy storage system at Pingjhen Plant by its Energy Infrastructure and Industrial Solutions Business Group (EISBG), thereby becoming an integral part of "Electricity Sharing" in the ancillary service market.

Delta's Spokesperson Mr. Jesse Chou (second from left), Chief Operating Officer Mr. Simon Chang (second from right), EISBG President Mr. J.J. Chang (first from right), and EISBG Senior Director Dr. Tsu-Hua Ai (first from left) provided insights into Delta's overall expansion of energy infrastructure during a press conference held at Chungli Plant 5

Delta's energy storage system has successfully passed Taipower's three types of regulation reserve test, namely dReg0.25, dReg0.5, and sReg, and performs dReg0.25, the most demanding dynamic regulation reserve, around the clock. The system installed at Pingjhen Plant is Delta's sixth MW class large-scale energy storage system in Taiwan that has been successfully connected to the power grid. The launch of this system at Pingjhen Plant serves as a testament to the implementation of energy infrastructure solutions with a view to creating a new engine for driving green energy through the provision of highly efficient and stable energy.

"While energy storage systems cover a wide range of applications and involve technical barriers, Delta possesses our own technology and production capabilities from top to bottom while relying on our team members who have experienced and overcome various problems from the ground up, one step at a time," shared EISBG President Mr. J.J. Chang. "In the light of a series of challenges such as the global shortage of raw materials, the COVID-19 pandemic, and the shipping crisis last year, Delta's energy storage team has been able to provide immediate responses, carry out quick adjustments, uphold accountability, and make deliveries as promised. Only then can we open the main artery of energy storage and provide safe and highly efficient energy storage solutions to help customers become successful on an on-going basis."

One-stop energy storage solution for stable power supply and carbon reduction

Energy storage systems are a good match with renewable energy. Aside from storing and transferring excess renewable energy for use at other times, energy storage systems can also help regulate the balance of electricity supply and demand on the power grid so that the power system becomes more stable while not wasting any green energy. This not only allows for good power quality, but also achieves the purpose of carbon reduction.

Delta's extensive and diverse experience in building energy storage applications covers traditional power plants, solar power plants, industrial and commercial sectors, EV charging stations, and micro-grids for various sites, including communities, campuses, factories, outlying islands, and coastal areas. With hardware and software development, manufacturing, quality control, system integration, and verification capabilities, Delta has developed an energy storage solution that features "one-stop services," including a simulation tool for use in the initial stage, power conditioning system (PCS), battery energy storage system (BESS), and energy management system (EMS) for overall system maintenance, to provide customers with the most efficient system configuration for their applications that significantly reduces the difficulty of system integration and shortens testing time. This energy storage solution, which was formed through technology integration, not only meets a power plant's requirements for an energy storage system, but also enables its management unit to purchase all the hardware and software products required to build the system in one go. This simplifies cumbersome communication and maintenance complexity through a single service channel and thus speeds up project completion. Additionally, its core technology, energy control, along with a battery management system, are also capable of adapting to different types and brands of energy storage batteries, which not only makes the most suitable match for various energy storage applications, but also creates a stable and reliable energy storage system for the power industry, large electricity consumers, as well as industrial and commercial sectors.

Delta honored with Taiwan Excellence Gold Award for its energy storage capabilities

Among the 1,156 products competing In this year's Taiwan Excellence Awards, Delta's energy storage system solution won over the panel of judges and received the Taiwan Excellence Gold Award, the highest honor in this prestigious event, thanks to its innovative technology. Facing the future trend of low-carbon grids, electric power should be conditioned and dispatched with energy storage systems as a buffer mechanism in order for power grids and renewable energy to work together steadily, so that renewable energy can become controllable, manageable, and dispatchable.

Consisting of a power conditioning system, a high-voltage lithium battery system, and the DeltaGrid® energy management system, this self-developed, Taiwan-made energy storage system solution achieves precise and highly efficient energy control and rapid response capabilities based on a unique multi-tasking algorithm. It is capable of delivering electricity to the power grid within 0.2 seconds while being involved in other energy storage applications in normal times, which enables the spare capacity of the energy storage system to be put to good use. While the design of the battery cabinet with separate compartments applied to this solution improves system safety and reduces risks, the modular design with high sales per unit area adopted in this solution makes it easy to configure, transport, install, maintain, and repair. At the same time, such a design can also assist large electricity consumers in industrial and commercial sectors as well as EV charging stations in a host of energy storage applications, such as peak shaving and valley filling, optimization of contract capacity and backup power, and participation in ancillary services.

Having experienced and overcome a series of power grid variables in the past, EISBG has accumulated experience in building various types of energy storage applications, including energy infrastructure solutions for solar energy, energy storage, EV charging infrastructure, and energy management. Coupled with its own technologies and local service teams, EISBG is able to ensure stable system operation through a high level of mastery in R&D, production, integration, and after-sales service. In the course of energy transition, EISBG enables a smooth journey to energy transition through the development of a steady, safe, and secure energy storage system, and thus makes a contribution to sustainable development.
