Houston-based Plus Power announced it has begun operating a new facility on Oahu, Hawaii.

The Kapolei Energy Storage, or KES, facility is “the most advanced grid-scale battery energy storage system in the world,” which will help transition the state's electric power from coal and oil to solar and wind, according to the company.

The KES battery project is located on 8 acres of industrial land on the southwest side of Oahu near Honolulu, and will use 158 Tesla Megapack 2 XL lithium iron phosphate batteries. It will offer the grid 185 megawatts of total power capacity and 565 megawatt-hours of electricity. This will act as an electrical "shock absorber" that will be served by combustion-powered peaker plants to respond in 250 milliseconds according to Power Plus.

"This is a landmark milestone in the transition to clean energy," Brandon Keefe, Plus Power's executive chairman, says in a news release. "It's the first time a battery has been used by a major utility to balance the grid: providing fast frequency response, synthetic inertia, and black start. This project is a postcard from the future — batteries will soon be providing these services, at scale, on the mainland."

The KES plant interconnects three of Hawaiian Electric's critical power generation facilities, which can enable KES to support the reboot of power plants in the event of a state-wide emergency.The KES batteries will help replace the grid capacity formerly provided by an AES coal power plant.

By June 2024, Plus Power aims to operate seven large-scale battery energy storage plants across Arizona and Texas. Last year, the company secured $1.8 billion in new financing for a handful of ongoing projects — most of which are in Texas.

Houston-based NRG Energy Inc. announced Jan. 7 that it has appointed Robert J. Gaudette as president and CEO. Gaudette took over as president effective Jan. 7 and will assume the role of CEO April 30, coinciding with the company's next stockholder meeting.

Gaudette, who previously served as executive vice president and president of NRG Business and Wholesale Operations, will succeed Lawrence Coben in the leadership roles. Coben will remain an advisor to NRG through the end of the year and will also continue to serve as board chair until April 30. Antonio Carrillo, lead independent director at NRG, will take over as board chair.

"Rob has played a central role in strengthening NRG’s position as a leader in our industry through strategic growth, operational excellence, and customer-focused innovation," Coben said in the news release. "He is a strong, decisive leader with extensive knowledge of our business, markets, and customers. The Board and I are confident that Rob is the right person to lead NRG forward and take the NRG rocket ship to new heights. I can’t wait to see what comes next.”

Gaudette has been with NRG since 2001. He has served as EVP of NRG Business and Market Operations since 2022 and president of NRG Business and Market Operations since 2024. In these roles, he led NRG’s power generation and oversaw its portfolio of commercial and industrial products and services as well as its market operations, according to the company.

He has held various executive leadership roles at NRG. He earned his bachelor's degree in chemistry from The College of William and Mary and an MBA at Rice University, where he was a Jones Scholar. He also served four years as an Army officer.

“It is an honor to be appointed NRG’s next CEO at this transformative time for the energy sector and our company,” Gaudette said in the release. “With NRG’s electricity, natural gas and smart home portfolio, we are ideally positioned to meet America’s evolving energy needs. I am grateful to Larry and all my NRG colleagues, both past and present, who built our great company and positioned us for the future. I look forward to leading our incredible team to deliver affordable, resilient power for the customers and communities we serve, while creating substantial value for our shareholders.”

In addition to its traditional power generation and electricity businesses, NRG has been working to develop a 1-gigawatt virtual power plant by connecting thousands of decentralized energy sources by 2035 in an effort to meet Texas’ surging energy demands.

The company announced partnerships last year with two California-based companies to bolster home battery use and grow its network. NRG has said the VPP could provide energy to 200,000 homes during peak demand.
