NextEra Energy has signed agreements with the US Department of Commerce and the Government of Japan covering funding for up to 10 GW of new natural gas-fired generation in Texas and Pennsylvania.

The agreements release an initial $3.3 billion tranche of funding, with the first generating capacity potentially coming online by the end of 2028. The projects are expected to be completed by 2032.

NextEra will develop the projects as part of a wider portfolio of more than 30 proposed “energy hubs”. The funding forms part of Japan’s $550 billion investment commitment to the US announced under the countries’ trade agreement in March, with the projects subsequently approved by President Donald Trump.

The developments are aimed at matching new, electricity-intensive demand with dedicated generation, particularly from digital infrastructure. NextEra’s approach is based on its “bring your own generation” model, in which large loads are paired with new power supplies rather than relying entirely on existing grid capacity.

The initial funding will support development work including deposits for long-lead equipment such as gas turbines and the selection of engineering, procurement and construction contractors.

The largest of the two projects is the proposed South Mon project in Pennsylvania, which is expected to provide 4.3 GW of natural gas generation. In Texas, NextEra is also developing new gas capacity intended to serve growing electricity demand.

US Commerce Secretary Howard Lutnick said the initial investment would begin construction of infrastructure capable of bringing up to 10 GW of gas generation to the two states.

John Ketchum, Chairman, President and CEO of NextEra Energy, said the company’s hub strategy had been developed specifically to capture “bring your own generation” opportunities.

“By pairing large-load demand with dedicated generation, we can move quickly to support the growth of critical digital infrastructure while ensuring the costs are not borne by American homes and businesses,” he said.

The developments remain subject to permitting and other regulatory requirements. NextEra said additional project details and schedules would be released as development progresses.

The agreements underline the growing role of natural gas in meeting rapidly rising US electricity demand, particularly where large new loads such as data centres require firm power before additional grid capacity can be built.
