The Twelvemile Solar 1 and 2 projects are a combined 153 MW solar development located in Bryan County, Oklahoma, and they have since entered commercial operation, according to LRE. The company said the pair delivers power under firm transmission service to Oklahoma Gas and Electric, supporting regional reliability as electricity demand grows.

Twelvemile 3, a 200 MW project in Johnston County, remains under construction, which takes the planned LRE Oklahoma portfolio to 725 MW. That solar growth now sits alongside the Hugo Plant Expansion, where Western Farmers Electric Cooperative is adding about 400 MW of gas turbines to balance variable renewable output in the same part of the state.
Project Overview
- Project Name: Twelvemile Solar 1 and 2
- Location: Bryan County, near Durant, Oklahoma
- Project Value: Not publicly disclosed for these two projects, while LRE puts its full 725 MW Oklahoma portfolio at about $1.5 billion
- Client or Owner: LRE (Leeward Renewable Energy)
- Capacity: 153 MW combined, made up of Twelvemile I at 100 MW and Twelvemile II at 52.2 MW
- Key Components: Utility scale solar with sheep grazing for vegetation management and pollinator friendly habitat
- Offtake: Google power purchase agreements, with delivery through Oklahoma Gas and Electric under firm transmission service
- Status: Commercial operation reached, according to LRE’s July 2026 release, with construction having begun in 2025
- Strategic Impact: About $148.8 million in projected state and local tax revenue and more than 2,000 construction jobs across the LRE Oklahoma portfolio, according to LRE
- Related Phase: Twelvemile 3, a 200 MW project in Johnston County, under construction

Reported 30th July 2025: Construction is underway for the Twelvemile Solar 1 & 2 projects in southern Oklahoma. These solar facilities are expected to be among the largest of their kind in the state once completed. The 152.5-megawatt (MW) joint solar installation is being developed by Leeward Renewable Energy (LRE) as part of its growing presence in Oklahoma’s clean energy market.
At peak construction, Twelvemile 1 & 2 will produce up to 350 local jobs and $29 million in estimated state and local property taxes over their lifespan. The two sites are expected to alleviate strain on the grid during peak-demand seasons and contribute to overall regional economic growth.
This investment not only benefits a stronger grid but also ignites regional development through job creation, business attraction and infrastructure growth in southern Oklahoma,” stated Eran Mahrer, LRE’s Chief Commercial Officer. “We are dedicated to community-based development and ethical sourcing that yields long-term value.
Twelvemile portfolio
LRE bought the Twelvemile portfolio from Red River Renewable Energy LLC, a joint venture between SunChase Power LLC-Eolian LP. Both were part of the early development phase, which helped shape today’s signature clean energy project in the area.
“These solar facilities will be the largest of their kind in Oklahoma when completed,” said Eolian CEO Aaron Zubaty. “They’ll be important in helping to mitigate grid stress during hot summer afternoons and promoting a more reliable energy mix.”
Twelvemile projects form part of LRE’s wider 724 MW Oklahoma solar portfolio, including the nearby projects in Mayes County. Although the spotlight is on Twelvemile, it’s interesting to know that energy from this development will also fuel a long-term energy contract with Google, backing its goal of 24/7 carbon-free electricity.
Under a series of power purchase agreements facilitated by LevelTen Energy’s LEAP platform, electricity from Twelvemile and other LRE developments in Oklahoma will be marketed to the Grand River Dam Authority and eventually be used to power Google data centers in Oklahoma.
SunChase Power Vice President Teran Smith emphasized that early-stage coordination made the project possible. “The Mayes and Twelvemile Solar projects are the result of strategic siting and early collaboration. We’re proud to see these investments generate long-term value for Oklahoma’s communities and grid.”
