Samsung SDI, Alpha Omega Power sign 1-GWh ESS supply deal

Samsung SDI America signed an agreement to supply 1 gigawatt-hour of energy storage systems to U.S. developer Alpha Omega Power, with construction of projects scheduled to begin next year in the Western Electricity Coordinating Council and Electric Reliability Council of Texas markets. The deal brings the companies’ total agreements to 1.5 gigawatt-hours. Samsung SDI will supply its Samsung Battery Box 1.7, with cells and modules made at the StarPlus Energy plant in Kokomo, Indiana. Alpha Omega Power said the agreement supports its growth and domestic supply chain.

The Samsung Battery Box 1.7 uses nickel-cobalt-aluminum batteries and has 17 percent higher energy density than the Battery Box 1.5 while retaining the same 20-foot footprint.

The system uses artificial intelligence-powered algorithms for early anomaly detection and battery life prediction and is designed for 25 years of continuous operation.

The Battery Box 1.7 meets National Fire Protection Association 855 and Underwriters Laboratories 9540 safety standards.

Samsung SDI’s Enhanced Direct Injection technology delivers fire-extinguishing agents directly into individual battery modules.

Samsung SDI said deliveries under the agreement are scheduled to be completed by the end of this year.

Samsung SDI said Monday that its U.S. subsidiary, Samsung SDI America, has signed a 1-gigawatt-hour agreement to supply energy storage systems (ESS) to Alpha Omega Power, a U.S. utility-scale battery storage developer and independent power producer.

The latest deal brings the total volume of agreements between the two companies to 1.5 gigawatt-hours, including an initial contract signed late last year.

Alpha Omega Power plans to deploy the systems in large-scale power projects aimed at strengthening grid reliability and meeting rising electricity demand. Construction is scheduled to begin next year in the Western Electricity Coordinating Council and Electric Reliability Council of Texas markets.

Under the latest agreement, Samsung SDI will supply its Samsung Battery Box 1.7, an integrated ESS equipped with nickel-cobalt-aluminum batteries. All cells and modules will be manufactured at the StarPlus Energy plant in Kokomo, Indiana, with deliveries scheduled to be completed by the end of this year.

Samsung Battery Box 1.7 offers 17 percent higher energy density than its predecessor, Samsung Battery Box 1.5, while retaining the same 20-foot footprint. It uses artificial intelligence-powered algorithms for early anomaly detection and battery life prediction and is designed for 25 years of continuous operation.

The system meets safety standards including National Fire Protection Association 855 and Underwriters Laboratories 9540. It also features Samsung SDI's proprietary Enhanced Direct Injection technology, which delivers fire-extinguishing agents directly into individual battery modules.

Samsung SDI's PrismStack prismatic battery technology, which analysts say offers performance and safety advantages, has helped the company secure contracts in North America. It is currently the only non-Chinese supplier of prismatic batteries for energy storage systems in the region. Compared with pouch-type batteries, its prismatic batteries offer durability and fire safety advantages that appeal to U.S. energy companies.

“American-made ESS from Samsung SDI will play an important role in Alpha Omega Power’s continued growth,” said Paul Choi, CEO of Alpha Omega Power. “This second agreement strengthens our domestic supply chain supporting the next generation of energy infrastructure.”

Fabrice Hudry, president of the ESS team at Samsung SDI America, said the company would continue to expand its North American business by leveraging its technology and local production capabilities.

三星SDI美国公司签署协议，将向美国开发商Alpha Omega Power供应1吉瓦时的储能系统，项目建设计划于明年在西部电力协调委员会（WECC）和德克萨斯州电力可靠性委员会（ERC）辖区内启动。该协议使双方的总供应量达到1.5吉瓦时。三星SDI将提供其Samsung Battery Box 1.7电池盒，其电芯和组件由位于印第安纳州科科莫的StarPlus Energy工厂生产。Alpha Omega Power表示，该协议有助于其业务增长和国内供应链的完善。

三星 Battery Box 1.7 采用镍钴铝电池，能量密度比 Battery Box 1.5 高 17%，同时保持了相同的 20 英尺占地面积。

该系统采用人工智能算法进行早期异常检测和电池寿命预测，设计寿命为 25 年。

Battery Box 1.7 符合美国国家消防协会 855 和美国保险商实验室 9540 安全标准。

三星SDI的增强型直接注入技术可将灭火剂直接输送到各个电池模块中。

三星SDI表示，根据协议进行的交付计划将于今年年底前完成。

三星SDI周一表示，其美国子公司三星SDI美国公司已签署一项1吉瓦时的协议，向美国公用事业规模电池储能开发商和独立电力生产商Alpha Omega Power供应储能系统（ESS）。

最新达成的协议使两家公司之间的协议总量达到 1.5 吉瓦时，其中包括去年底签署的初始合同。

Alpha Omega Power计划在大型电力项目中部署这些系统，旨在增强电网可靠性并满足日益增长的电力需求。项目建设预计将于明年在西部电力协调委员会和德克萨斯州电力可靠性委员会的辖区内启动。

根据最新协议，三星SDI将供应其三星电池盒1.7，这是一款集成式储能系统，配备镍钴铝电池。所有电芯和模块都将在位于印第安纳州科科莫的StarPlus Energy工厂生产，预计将于今年年底前完成交付。

三星电池盒 1.7 的能量密度比其前代产品三星电池盒 1.5 提高了 17%，同时保持了相同的 20 立方英尺占地面积。它采用人工智能算法进行早期异常检测和电池寿命预测，并设计用于连续运行 25 年。

该系统符合包括美国国家消防协会 855 和美国保险商实验室 9540 在内的安全标准。它还采用了三星 SDI 的专有增强型直接注入技术，可将灭火剂直接输送到各个电池模块中。

分析人士称，三星SDI的PrismStack棱柱形电池技术在性能和安全性方面均具有优势，并已帮助该公司在北美市场斩获多项合同。目前，三星SDI是该地区唯一一家非中国籍的储能系统棱柱形电池供应商。与软包电池相比，三星SDI的棱柱形电池具有更高的耐用性和更强的防火安全性，深受美国能源公司的青睐。

“三星SDI提供的美国制造的储能系统将在Alpha Omega Power的持续增长中发挥重要作用，”Alpha Omega Power首席执行官Paul Choi表示。“第二份协议加强了我们的国内供应链，为下一代能源基础设施提供支持。”

三星SDI美国公司ESS团队总裁Fabrice Hudry表示，公司将继续利用其技术和本地生产能力来扩大其北美业务。
