JERA Acquires Shale Gas Assets in Louisiana
JERA, a global energy leader and Japan’s largest power generation company, has announced that it has, through its subsidiary JERA Americas Inc., reached an agreement with Williams and GEP Haynesville II, LLC to acquire 100% of their interests in the South Mansfield upstream for $1.5 billion.
The Haynesville acquisition, which is subject to customary closing conditions and regulatory approvals, supports JERA’s strategy of building a diversified, responsible, and resilient asset portfolio.
JERA will acquire its interest in the Haynesville asset, which currently produces more than 500 MMscfd and includes 200 undeveloped locations. The transaction includes a future investment plan under which JERA will increase total production to 1 BSCFD.
The Haynesville Acquisition’s strategic value is supported by robust current production and proven reserves, established gathering, treating and transport infrastructure, and proximity to Gulf Coast LNG and data center hubs.
The Haynesville Acquisition builds on JERA’s substantial and growing presence in the US, including its recent announcement of the largest offtake of US LNG from a single buyer, 5.5 million tonnes per year for 20 years, and the Blue Point low-carbon ammonia development project. JERA also owns, in whole or in part, 10 power generation assets across the country.
JERA Americas’ CEO John O’Brien said that the US energy sector is leading the way in the global LNG market and JERA’s investments have lined up accordingly.
He said that the upstream Haynesville acquisition is a strategic addition to their asset portfolio, enabling them to advance the company’s unique supply chain expertise while deepening their commitment to Americas’ energy future.
Expanding US Partnership
JERA’s Chief Low Carbon Fuel Officer Ryosuke Tsugaru said that the Haynesville acquisition substantially expanded their partnerships in the US.
“The benefits are clear: enhanced diversification for JERA’s LNG value chain, expanded global reach across the gas value chain and overall risk mitigation in a volatile energy market. The project thus clearly aligns with our strategic priorities and reinforces our core mission to provide a stable and secure energy supply globally,” Tsugaru added.
According to a report in New Orleans City Business, JERA currently buys a total of 3.5 million tons of LNG annually from Freeport LNG in Texas and Cameron LNG in Louisiana under long-term contracts.
So far in 2025, JERA has signed deals to secure 6.5 million tons per year from US LNG suppliers located in Texas, Louisiana and Alaska. JERA also entered into an approximately 1.0 million ton-per-year LNG offtake agreement with Venture Global CP2 in 2023, with first deliveries expected in 2027.
Earlier this year, JERA and investment partners CF Industries and Mitsui & Co announced that they will spend about $4 billion to build the largest low-carbon ammonia plant in the world at a site in Ascension Parish.
Through its renewables subsidiary JERA Nex, the company owns and operates the Oxbow solar farm in Point Coupee Parish. The 300 MW facility, acquired in 2024, is the largest solar farm in Louisiana. The company also owns, in whole or in part, 10 power generation assets across the country.
