Eolian’s proven and enviable track record is evidenced by the successful funding and development of nearly 30 GW of operating or under-construction energy storage, solar, and wind generating capacity throughout the country. Eolian currently operates a growing portfolio of wholly-owned utility-scale battery energy storage projects, and was an early innovator in the development of GW-scale co-located gen+load datacenter and industrial project sites across the US.

What we do
Since 2005, Eolian has been an innovative investor in energy projects, including the invention of the renewable energy royalty structure that has now become an industry standard. In contrast to many firms that raise capital with short-term buy and sell strategies, Eolian and its partners have long-term views of 30+ years. This allows for a unique perspective on energy investing and an alignment with the long-term generation planning perspective of utilities, independent power producers and power market operators.
LRE Begins Construction on Twelvemile Solar 1 & 2 in Oklahoma
The 152 MW solar project will deliver clean, dependable power, create local jobs, and support economic and community growth across southern Oklahoma.
Jul 30, 2025 9:00 AM
DALLAS--(BUSINESS WIRE)--LRE (Leeward Renewable Energy), a leading U.S. renewable energy company, today announced the start of construction on its Twelvemile Solar 1 & 2 projects, a combined 152-megawatt (MW) solar facility located in southern Oklahoma. The projects are part of LRE’s broader 724 MW solar portfolio in the state, which also includes the previously announced Mayes County Solar Portfolio.
Twelvemile 1&2 reflects LRE’s ability to bring large-scale projects online quickly with power delivery expected to begin in early 2026. These projects expand access to reliable, cost-effective energy and enable continued investment and business growth across the region.
“As America’s energy needs grow, projects like Twelvemile 1&2 are critical to ensuring reliable, affordable power,” said Eran Mahrer, Chief Commercial Officer at LRE. “This investment not only supports a more resilient grid but also fuels regional growth by creating jobs, attracting businesses, and strengthening infrastructure in southern Oklahoma which is critical in maintaining and continuing to attract economic development so important to the region. Guided by responsible development and a deep commitment to domestic content, local sourcing, and community-focused growth, we are delivering projects with lasting impact.”
LRE acquired the Twelvemile portfolio from Red River Renewable Energy LLC, a joint venture between SunChase Power LLC and Eolian LP, and collaborated closely with both companies during the early development stages.
“These solar projects will be the largest facilities of their type in Oklahoma once completed and will immediately help to reduce strain on the grid during peak summer hours of demand that define resource adequacy requirements,” added Aaron Zubaty, CEO of Eolian. “Power markets and resource supply portfolios that embrace multiple technologies can best withstand the increasing impact of severe weather events and fuel supply disruptions.”
Why Texas’s ‘cut-throat’ approach to net zero is paying off

By Melissa Lawford
Bobby Helmers used to be an oilman.
For years, he worked leasing land for petroleum companies and at one point had as many as nine oil wells on his ranch in West Texas.
But those wells have long been plugged up.
“It’s not that I was dissatisfied with the oil,” says Helmers. “It’s just that production was depleting. They became no longer economically feasible.”
Now, instead, the 84-year-old Trump voter has six wind turbines spinning on his ranch.
Standing 300ft high, they make up the north-eastern end of a 76-turbine farm that stretches into the distance and is owned by French utilities company Engie, which pays Helmers handsomely for the privilege.
“If you’re talking about bottom-line dollars, the wind turbines make more for the ranch than the cattle do,” says Helmers. “They’re a blessing.”
His shift to renewables may seem surprising, especially given that he lives in the largest oil-producing state in the largest oil-producing country in the world.
But the free-market, Republican region has also now become far and away America’s biggest generator of renewable energy, as well as producing nearly 43pc of all US crude.
Last year, the state generated 124,934 gigawatt hours of wind energy, enough to power 11.6 million homes and nearly three times the second-largest wind-producing state.
Behind California, it is also America’s second-largest producer of solar power, but it is catching up rapidly.
PGE Energizes 475 MW of Battery Energy Storage to Boost Grid Reliability and Keep Costs Low for Oregonians
News provided by Portland General Company Aug 07, 2025, 07:48 ET
PORTLAND, Ore., Aug. 7, 2025 /PRNewswire/ -- Portland General Electric (PGE) today announces the completion of three new utility-scale battery energy storage systems, adding 475 megawatts (MW) and more than 1.9 gigawatt hours (GWh) of dispatchable capacity to serve the Portland metro area.
Together, these three facilities can power roughly 300,000 homes for four hours during peak demand or when power is limited due to weather or unexpected interruptions. Additionally, they offer flexibility and backup capacity to ensure that PGE customers have access to electricity when they need it most.
"Batteries play an important role in helping PGE build a more flexible, reliable and diverse generation portfolio," said Darrington Outama, PGE Senior Director of Energy Supply. "In addition to providing power during peak hours every day, batteries enhance our ability to respond to sudden changes in the grid and help keep energy supply and demand balanced. For customers, that means more stable and reliable power, all at the lowest possible cost."
Strategically located at key substations in North Portland, Troutdale and Hillsboro, these four-hour lithium-ion battery energy storage systems are integrated into PGE's system to better align the production and consumption of electricity, which reduces strain on the grid. Battery storage reduces PGE's reliance on expensive short-term electricity purchases, helping stabilize energy costs, limit price volatility for customers, and support the integration of intermittent sources like wind and solar.
Two of the newly operational facilities, successfully developed and awarded to Eolian, L.P. (Eolian) through Portland General Electric's 2021 All-Source Request for Proposals (RFP) process, include:
Seaside: A 200 MW PGE-owned facility located in North Portland and delivered to PGE by Eolian, L.P. (Eolian) under a fixed-cost Build-Transfer Agreement (BTA). The facility achieved commercial operation in July 2025.
Sundial: A 200 MW facility in Troutdale, developed by Eolian and operated by NextEra Energy Resources under a 20-year storage capacity agreement with PGE. The facility achieved commercial operation in December 2024.
Constable: A 75 MW PGE-owned facility located in Hillsboro and constructed for PGE under an engineering, procurement and construction agreement with Mortenson. The facility achieved commercial operation in December 2024.
"Battery energy storage systems sited at major substations radically improve the use of existing high voltage transmission lines, avoiding expensive or challenging new grid upgrades and providing a low-cost load growth solution through existing infrastructure," said Aaron Zubaty, CEO of Eolian.
In addition to the three new large-scale battery facilities, PGE completed its 17 MW Coffee Creek Battery Storage system near Wilsonville in 2024. The completion of Seaside, Sundial, Constable and Coffee Creek brings PGE's large-scale battery storage capacity to 492 MW.
Financially Backed by Global Infrastructure Partners (GIP), part of BlackRock
