Key Takeaways

  • Sam Lissner of Ridgewood Infrastructure argues that US energy transition deals must pencil out on pure operational savings rather than tax credits or policy support.
  • Surging power loads from AI data centers, industrial reshoring, and electrification are creating direct commercial demand for grid efficiency and battery storage.
  • Ridgewood targets mid-market businesses, such as portfolio companies focused on lowering operating expenses for commercial customers, where customer economics drive the contract.
  • Legislative shifts following packages like the One Big Beautiful Bill Act demonstrate why underwriting project returns around government incentives exposes capital to regulatory risk.

Underwrite the Customer OpEx, Not the Tax Credit

When political winds shift in Washington, infrastructure models built on federal subsidies unravel fast. Lissner points out that managers who tied their underwriting to regulatory continuity are finding themselves exposed as policy support fluctuates.

“It's pretty clear to me that the zeitgeist around the energy transition in the US has changed as the political winds have shifted. And policy does matter in this area,” Lissner said. Yet the mistake lies in treating policy as the core thesis rather than a temporary kicker.

For mid-market infrastructure funds, the discipline begins with basic commercial reality. “We have an energy efficiency company in our portfolio that its expressed purpose is to focus on reducing its customers' operating expenses,” Lissner noted. “And so as we think about the opportunity set, we don't really begin with the question, okay, which subsidy is available to us? We begin with the question of what does the customer need?”

When an asset cuts a corporate customer's electric bill or secures backup power for an industrial facility, the contract holds regardless of who controls Congress. The service solves a real operational problem, generating steady cash flows that do not depend on annual budget appropriations.

The Commercial Pull of AI and Grid Load Growth

For two decades, US electricity demand stayed mostly flat. That era is over. The rapid buildout of artificial intelligence data centers, combined with domestic manufacturing and fleet electrification, has caught regional grid operators unprepared. This structural supply shortage creates direct commercial demand for power solutions.

“Our broader view is actually that the energy transition is durable because the underlying drivers are economic,” Lissner explained. “As we've talked about, demand for power is growing. You have the AI transformation and data centers that are creating electricity needs.”

Data center operators cannot wait seven years for traditional utility interconnection queues. They are actively contracting for behind-the-meter generation, on-site battery storage, and energy management software. These buyers are paying for speed, uptime, and cost containment. They are not waiting for state grants to approve their capital expenditures.

“Policy support can improve a project, but really we are focused on opportunities where the subsidy is incremental and where the demand and the underlying economics are strong enough to stand on their own,” Lissner said. Mid-market funds operating in water utilities, short-line rail, and distributed power build defensible cash flows by focusing on these exact supply bottlenecks.

Why It Matters

This shift marks a clear line between infrastructure managers who run merchant risk disguised as green growth and those who run disciplined credit-like assets. Underwriting assets to stand on raw customer demand insulates mid-market portfolios from political cycles. As large-cap funds struggle with slowing subsidy disbursements, capital will favor mid-market operators who treat government incentives as unpriced upside rather than base-case yield.
