Battery Energy Storage System (BESS) projects worldwide have gained prominence as key components in the transition to a more sustainable and resilient energy infrastructure. These projects involve the deployment of large-scale battery systems to store and manage electrical energy.

The global energy landscape is witnessing a shift toward diverse battery technologies, including lithium-ion and emerging options like sodium-ion batteries. These projects play a vital role in supporting the increasing penetration of renewable energy by storing excess power during peak generation periods and releasing it when demand is high.

As technology advances and energy policies evolve, BESS projects continue to be at the forefront of efforts to build a more sustainable and reliable energy infrastructure across the globe. Ongoing developments in this field underscore the importance of energy storage in creating a flexible and resilient grid capable of accommodating the demands of the modern energy landscape.

Hubei, China Project BESS

  • The project, located in Qianjiang, Hubei province, has already begun construction.
  • Construction has commenced on a large battery energy storage system (BESS) project in Hubei, China.
  • Sodium-ion technology is considered a commercially mature alternative to lithium-ion for BESS.
  • Sodium-ion batteries are an emerging alternative to traditional lithium-ion batteries. They use sodium ions as the charge carriers instead of lithium ions. Sodium is more abundant and less expensive than lithium, making sodium-ion batteries a potentially cost-effective and sustainable energy storage solution.
  • The construction of a sodium-ion BESS project in Qianjiang, Hubei province, China, indicates the country’s commitment to exploring alternative battery technologies for energy storage. The use of sodium-ion batteries in this project suggests a focus on developing technologies that can contribute to more sustainable and affordable energy storage solutions.
  • According to Shanghai Metals Market (SMM), the project has already started.
  • The Qianjiang Municipal People’s Government released a three-year plan in November 2023, which highlighted the BESS project.
  • The project was initially planned to be 100MW/200MWh, but recent reports indicate it will be 50MW/100MWh.
  • The project will require an investment of RMB200 million (US$27.8 million).
  • Regardless of the capacity, it will be the largest BESS using sodium-ion technology.
  • The sodium-ion BESS is being developed by Datang Hubei Energy Development, owned by the state-owned Assets Supervision and Administration Commission of the State Council (SASAC).
  • The completion of the project in 2024 suggests that China is actively working on expanding its energy storage infrastructure to support the integration of renewable energy sources and enhance grid stability.

Indiana project US, BESS

  • AES Indiana has received approval for the Pike County Battery Energy Storage Project.
  • The project has been approved by the Indiana Utility Regulatory Commission (IURC).
  • AES Corporation’s regional utility subsidiary has received regulatory approval for a 200MW, 4-hour BESS project in Indiana, US.
  • The Pike County Battery Energy Storage Project is expected to be operational by December of this year.
  • The project will have a capacity of 200MW/800MWh.
  • The battery energy storage system will be located at AES Indiana’s Petersburg Generating Station.
  • AES Indiana plans to convert the facility to gas and develop wind, solar PV, and additional battery projects.

Texas rules, BESS

  • The Public Utility Commission of Texas has ordered ERCOT, the state’s grid operator, to rescind state-of-charge (SOC) rules for BESS.
  • The Commission’s decision was communicated through a letter signed by the interim chair and two of its four commissioners.

Utility commissions, like the Public Utility Commission of Texas, are regulatory bodies responsible for overseeing and regulating the activities of utilities within their jurisdiction. This includes setting rules and standards to ensure the reliability and efficiency of the energy grid.

State-of-charge rules for BESS refer to regulations or guidelines that dictate how much energy a battery should retain (or not retain) in various states of charge to comply with grid requirements. These rules are often set to optimize the performance of energy storage systems and ensure grid stability.

If the PUCT has ordered ERCOT to rescind state-of-charge rules for BESS, it could indicate a shift in regulatory policies or a reevaluation of the role of energy storage within the Texas grid. The decision might be influenced by factors such as technological advancements, changes in grid dynamics, or the need for flexibility in managing energy storage resources.
