TOKYO - GE Vernova announced that the Japanese joint venture Goi United Generation (GIUG)’s Goi Thermal Power Station achieved the start of commercial operation in Chiba Prefecture, part of the Greater Tokyo Area. The joint venture comprises Japan's largest power producer by capacity JERA, ENEOS Power and regional utility Kyushu Electric Power. The plant, powered by three GE Vernova 9HA.02 gas turbines, the first of its kind installed in Japan, is expected to deliver more than 2.3 Gigawatts (GW) to the grid to help provide reliable electricity and the stable supply of electricity in Japan.

In addition to the gas turbines, for this project, GE Vernova delivered three GE Vernova Heat Recovery Steam Generators (HRSGs), with the Pressure Part Modules built in GE Vernova’s factory in Changwon, South Korea and delivered each HRSG in only three prefabricated Supermodules assembled in Tongyeong, South Korea, and then transported across the ocean to Japan. The HRSG plays an important part in a combined cycle power plant as it uses heat from the gas turbine exhaust to generate super-heated steam, which powers a steam turbine to create up to 50% more energy without any additional fuel.

The installation of advanced GE Vernova HA equipment and Toshiba's steam turbines and generators renewed the power plant initially built in the 1960s and retired in 2018, enabling an estimated 16 percent reduction of CO2 emissions compared to the old facility.

GE Vernova worked with Toshiba to integrate the currently largest HRSG Supermodules in the world at the Goi plant following a very complex, and safely delivered, transport from South Korea to Japan. Each Supermodule weighs approximately 2,500 metric tons and measures between 43 to 46 m in height, almost as tall as The Arc de Triomphe in Paris or a 15-floor building. Despite space limitations and logistical challenges, GE Vernova and Toshiba jointly adapted to unique circumstances, and successfully delivered these Supermodules and completed the Goi plant.

HOMER CITY, PA -- Homer City Redevelopment (HCR) and Kiewit Power Constructors recently announced the future of the former Homer City Generating Station. Homer City - previously the largest coal-burning power plant in Pennsylvania - will be transformed into a more than 3,200-acre natural gas-powered data center campus, designed to meet the growing artificial intelligence (AI) and high-performance computing (HPC) needs of the innovative technology companies shaping America’s digital future.

GE Vernova will provide seven high efficiency 7HA.02 hydrogen-enabled, gas-fired turbines, with the first deliveries expected to begin in 2026. The Homer City Energy Campus will be built by Kiewit Power Constructors Co., one of the leading engineering, procurement and construction (EPC) contractors in the country. Much of the critical infrastructure for the project is already in place from the legacy Homer City plant, including transmission lines connected to the PJM and NYISO power grids, substations and water access. Construction of the site is expected to commence this year and is expected to begin producing power by 2027.

Key attributes and benefits of the project are expected to include:

Delivery of up to 4.5 gigawatts (GW) of power to support AI-driven hyperscale data centers, while reducing greenhouse gas emissions by 60–65% per megawatt hour compared to the former coal plant.

Deployment of numerous previously secured long-lead power components coupled with sufficient generating capacity to serve multiple large data center customers and supply power to thousands of homes on the local grid.

An initial capital investment projected to exceed $10 billion for power infrastructure and site readiness, with data center development to inject billions more, making this the largest such investment in Pennsylvania’s history.

Importantly, energy production at the new Homer City Energy Campus will rely on natural gas produced in the Marcellus Shale Region of the U.S., and the project will help address the nation’s growing energy shortage - a crisis that will only intensify as demand surges to support the global race for dominance in AI and HPC technology. According to PJM Interconnection, L.L.C. (PJM) - the largest grid operator in the country- the Mid-Atlantic region in particular faces a looming energy capacity deficiency, with more than one fifth of the PJM system in the area expected to retire or reach the end of its useful life by the end of the decade.

LOS ANGELES-- Capstone Green Energy Holdings and Capstone Green Energy announced that Vergent Power, Capstone's distributor for the Upper Midwest, New England, and Eastern Canada, has secured an order for two Capstone C65 ICHP microturbines and a Vergent controller for the City of Winona's wastewater treatment plant in Minnesota. The new system, set to be commissioned by April 30, 2025, will double the facility's renewable energy output while maintaining its commitment to cost-effective operations.

The City of Winona has relied on Capstone technology for over 15 years, with an existing C65 microturbine that has surpassed 100,000 hours of runtime. This expansion project replaces the aging unit, adds a second C65 microturbine, and incorporates a Vergent remote monitoring controller. This allows Vergent to keep a pulse on the Capstone Combined Heat & Power (CHP) system - significantly enhancing the facility's energy sustainability.

The Capstone CHP system uses the facility's digester gas as fuel to generate electricity for the facility's consumption. The Capstone CHP's exhaust energy will be recovered by converting it to hot water, which is used to support the digester process heating loads. This CHP application reduces the facility's reliance on natural gas and provides resiliency in an affordable approach, all while sustainably lowering its carbon footprint.

By leveraging the federal Tax Credit (ITC) and a Department of Energy Industrial Training and Assessment Center Implementation Grant, the city was able to cover over 90% of the project's costs with these grants. This funding made this expansion project possible in the most affordable way.
