Wedoany.com Report-Apr. 24, GE Vernova has announced the start of commercial operations for the third block of the Goi Thermal Power Station in Chiba Prefecture, Japan. Owned by Goi United Generation (GIUG), a Japanese joint venture, the power plant was originally constructed in the 1960s and decommissioned in 2018. It has now been revitalized with modern technology to support Japan’s energy needs.

The upgraded facility features GE Vernova’s advanced HA equipment, including three 9HA.02 gas turbines and three Heat Recovery Steam Generators (HRSGs), paired with Toshiba’s steam turbines and generators. The HRSGs capture exhaust heat from the gas turbines to produce super-heated steam, powering steam turbines to generate up to 50% more energy without additional fuel. This upgrade is expected to reduce emissions by approximately 16%.

Masataka Sato, CEO of Goi United Generation, stated: “We’re proud that equipment of that size and tailored to withstand earthquakes was delivered to the Goi site safely—where it can play a crucial role supplying electricity for Japanese homes and businesses.” The revitalized plant is one of Japan’s largest LNG-fired power stations, delivering over 2.3 gigawatts of reliable electricity to the grid.

The HRSG Supermodules installed at the Goi plant are among the largest globally, each weighing around 2,500 metric tonnes and standing 43 to 46 meters tall. Designed to endure seismic activity, these units highlight advanced engineering tailored to Japan’s environmental conditions. Ramesh Singaram, president and CEO of GE Vernova Gas Power Asia, remarked: “We’re proud that equipment of that size and tailored to withstand earthquakes was delivered to the Goi site safely—where it can play a crucial role supplying electricity for Japanese homes and businesses.”

GE Vernova, with a 130-year presence in Japan, supports approximately half of the country’s gas power capacity. The company is collaborating with local partners to develop more efficient gas turbines and explore technologies for hydrogen and ammonia combustion, working alongside industry leaders like IHI to advance sustainable energy solutions.

The Goi Thermal Power Station’s revival underscores Japan’s commitment to reliable and cleaner energy production, leveraging cutting-edge technology to enhance efficiency and reduce environmental impact while meeting the electricity demands of homes and businesses.
