Private Equity Bets Big on Aging Hydropower to Fuel the AI Boom

NEW YORK, NY – October 01, 2026 — In the high-stakes race to power the artificial intelligence revolution, the most coveted asset isn't always a glittering new solar farm or a massive offshore wind project. Increasingly, it is the century-old, unassuming run-of-river hydroelectric plant quietly churning out power in rural America.

Today, GDEV Management-backed Relevate Power and Apollo Global Management-backed Eagle Creek Renewable Energy announced a strategic partnership that underscores a massive shift in how private capital is viewing legacy infrastructure. Under the agreement, Eagle Creek will absorb Relevate’s local operating staff and assume day-to-day management of its portfolio of small hydroelectric assets. It is a move that on its face looks like a simple operational handover, but beneath the surface, it reveals a calculated strategy by private equity titans to corner the market on reliable, clean baseload power.

With electricity demand surging to levels unseen in decades—driven by the voracious energy appetite of data centers, industrial reshoring, and widespread electrification—intermittent renewables like wind and solar are struggling to shoulder the burden alone. The grid needs power that is both green and always on. Small hydropower, long overlooked as an aging relic of the 20th century, is suddenly the missing puzzle piece.

The Hunt for Forgotten Baseload

To understand the gravity of this partnership, one must look at the scale of the players involved. Eagle Creek, acquired by Apollo in 2025, is a behemoth in the independent hydro space. It operates 85 hydroelectric facilities across 18 states, boasting a nearly 700-megawatt portfolio capable of powering over 260,000 homes. Relevate Power, formed in 2022 and backed by GDEV’s Fund I, is a smaller, more nimble outfit focused on redeveloping underutilized, sub-scale plants.

By handing the keys to Eagle Creek, Relevate is effectively plugging its assets into a massive institutional machine. "The hydropower market is in a period of significant growth as electricity demand surges beyond current generation levels," noted Neal Simmons, CEO at Eagle Creek, in the partnership announcement. "We will bring our operating expertise to oversee Relevate's hydropower projects, enabling us to provide clean, reliable energy to surrounding homes and businesses."

The mechanics of this deal are rooted in economies of scale. Managing isolated run-of-river facilities—which rely on natural water flow rather than large reservoirs—can be operationally intensive and cost-prohibitive for smaller firms. By transitioning Relevate’s roughly 29 local operators to Eagle Creek’s payroll, the partnership preserves institutional knowledge at specific sites while slashing the overhead costs that traditionally eat into the margins of distributed energy portfolios.

This isn't the first time these financial heavyweights have crossed paths. The groundwork for this operational merger was laid in December 2024, when Apollo funds and GDEV provided joint financing for Relevate’s acquisition of Gravity Renewables. That transaction more than doubled Relevate’s generation capacity, adding 40 megawatts of high-quality assets to a portfolio that already included historic sites like the Glendale facility on Massachusetts' Housatonic River and Comtu Falls in Vermont. Today's announcement is the logical next step: consolidate ownership, then consolidate operations.

Follow the Money: Scaling Up Small Hydro

For institutional investors, the appeal of small hydro lies in its unique market position. Building new, large-scale dams in the United States is virtually impossible today due to stringent environmental regulations and permitting bottlenecks. Consequently, the existing fleet of U.S. hydropower facilities—most of which were built between 1940 and 1970—acts as a finite, highly valuable resource with high barriers to entry.

Benjamin Baker, Managing Partner of GDEV Management, highlighted the financial rationale behind the move. "Together with Eagle Creek, we're helping strengthen Relevate's business model of providing operational improvements to underperforming hydro facilities," Baker stated. "This partnership will allow Relevate to expand its platform on a larger scale while significantly reducing overhead - promising long-term value for our investors and partners."

This is classic private equity playbook execution, applied to the energy transition. GDEV, which recently secured over $200 million for its second flagship fund, specializes in targeting operationally complex, middle-market infrastructure. By partnering with Apollo—an alternative asset manager with approximately $840 billion under management and a stated goal of deploying $100 billion into clean energy by 2030—GDEV derisks its portfolio while Apollo secures a steady pipeline of baseload assets to feed the growing demands of its broader energy transition investments.

Industry insiders note that the integration of smaller, distributed generation sites into a centralized operating platform is becoming a necessity. As power markets become increasingly volatile, the ability to dispatch consistent, low-carbon electricity from dozens of small nodes across the grid provides a lucrative hedge against the price swings of natural gas and the intermittency of solar.

Reviving Rural Run-of-River with Federal Cash

However, acquiring aging infrastructure is only half the battle; modernizing it is where the true value is unlocked. This is where federal industrial policy intersects with private capital. Since GDEV’s initial investment, Relevate has aggressively pursued modernization, bolstered by a $4.9 million grant from the U.S. Department of Energy (DOE) funded through the Bipartisan Infrastructure Law.

The federal capital injection is highly targeted. Approximately $2.9 million is earmarked for maintaining facility resilience, upgrading dam features, and improving overall safety infrastructure. The remaining $2.0 million is dedicated strictly to operational efficiency, with a mandate to achieve a minimum 3% increase in energy generation efficiency across the targeted projects.

For private equity firms, these grants act as a powerful multiplier. Taxpayer dollars are effectively subsidizing the capital expenditures required to bring mid-century turbines and sediment management systems into the modern era. Once upgraded, these facilities can often operate at efficiency rates exceeding 90%, providing a steady stream of cash flow with minimal ongoing fuel costs.

Furthermore, modernization opens the door to hybrid technological applications. Relevate has publicly emphasized a strategy of blending run-of-river hydro with on-site solar and battery storage. By co-locating these technologies, operators can smooth out seasonal variations in river flow, effectively creating a localized, 24/7 clean power plant.

The New Economics of Old Water

The Relevate-Eagle Creek partnership is a bellwether for the broader U.S. energy market. For decades, the narrative surrounding renewable energy has been dominated by the rapid deployment of utility-scale wind and solar. But as grid operators issue increasingly dire warnings about reliability shortfalls, the market is rediscovering the value of dispatchable baseload power.

Data center developers, driven by the computational demands of generative AI, are scouring the country for grid connections that can guarantee uninterrupted, zero-carbon electricity. A modernized run-of-river hydro facility, particularly one backed by the operational muscle of a giant like Eagle Creek, fits that profile perfectly.

What we are witnessing is the financialization and technological resurrection of America's oldest renewable energy source. By combining federal modernization grants with the ruthless efficiency of private equity asset management, firms like GDEV and Apollo are transforming forgotten rural infrastructure into critical nodes of the 21st-century economy. As the grid continues to strain under the weight of the digital revolution, the quiet, steady flow of old water may well prove to be one of the most lucrative investments of the decade.
