In 2026, energy is no longer evaluated as a readily available, low-cost input or a purely environmental choice. It is being priced as constrained, strategic infrastructure that’s exposed to grid bottlenecks, AI-driven demand, geopolitical supply-chain risk, and rapidly evolving federal priorities directly influencing Washington-sponsored incentives. 

For investors, developers, and advisors, the core question is no longer how clean an asset is, but whether it is reliable, still financeable under a host of new rules, and readily deployable for near-to-midterm development objectives. 

This virtual forum hosted by Marshall & Stevens in May of 2026 brought together senior leaders from international energy development, data center infrastructure, regulatory policy, and project finance law for a live, unscripted conversation examining how energy assets are being repriced, restructured, and reallocated in 2026 and beyond.

Why Repowering and Tax Credits Are Driving Valuation Needs

Recent changes to the federal tax code have created strict timelines for renewable energy projects to qualify for investment tax credits (ITC) and production tax credits (PTC).

To meet these deadlines, many project owners are choosing to repower existing facilities rather than build new ones. Repowering allows a project to upgrade or replace components while still qualifying for tax incentives.

At the same time, rapid data center development across the U.S. is increasing demand for reliable energy sources. This has further accelerated investment in both renewable and conventional energy infrastructure.

These trends have increased the need for independent valuation analyses to support repowering strategies and related transactions.


What Is the “80/20 Rule” in Energy Repowering?

A key issue in repowering is whether a project qualifies for tax credits under IRS guidance. One of the most important tests is the “80/20 Rule.”

In simple terms, this test evaluates whether:

  • At least 80 percent of a project’s value comes from new equipment
  • No more than 20 percent comes from existing, reused components

This determination directly affects eligibility for tax credits, which can significantly impact project economics.

Marshall & Stevens provides valuation analyses that help clients apply this rule, particularly for wind energy projects where it is most commonly used.


What Types of Energy Projects Are Involved?

Repowering and related valuation issues arise across a wide range of energy and infrastructure assets.

Renewable energy projects include:

  • Wind (onshore and offshore)
  • Solar
  • Geothermal
  • Fuel cells
  • Renewable natural gas
  • Battery energy storage systems (BESS)
  • Microgrids

Conventional energy projects include:

  • Oil and gas
  • Coal and nuclear power plants
  • Energy distribution systems
  • Oilfield services

These projects often involve long-lived, capital-intensive assets where tax treatment, financing structure, and future performance all depend on accurate valuation.


How Valuation Supports Tax Credits and Transactions

Energy projects frequently rely on multiple revenue streams and incentives, including:

  • Investment tax credits (ITC)
  • Production tax credits (PTC)
  • Renewable energy credits (RECs)
  • Capacity payments and other contractual revenues

Valuation plays a central role in determining how these benefits are recognized, allocated, and monetized within a transaction.

Marshall & Stevens works with investors, developers, legal counsel, and auditors to ensure that valuation analyses reflect current guidance, rulings, and interpretations.


What Types of Valuation Services Are Provided?

Energy and infrastructure transactions typically require more than a single valuation. Assignments often include:

These analyses support decisions across financing, reporting, tax compliance, and dispute resolution.


How Regulated Utilities Are Valued

Some energy assets operate within regulated utility structures, which introduces additional complexity.

Regulated utilities earn revenue based on approved rates set by federal and state agencies. These rates are designed to allow:

  • Recovery of invested capital
  • A reasonable return on that capital

Valuation in this context requires understanding:

  • Rate-setting frameworks and regulatory constraints
  • Capital investment cycles and reinvestment needs
  • Market benchmarks from comparable utilities

Analyses often incorporate:

  • Rate case history and return trends
  • Capital expenditure requirements
  • Market-based and income-based valuation methods

Who Uses These Valuation Analyses?

Clients include:

These stakeholders rely on independent valuation opinions to support transactions, meet regulatory requirements, and understand the financial implications of complex energy investments.


How Marshall & Stevens Supports Energy Transactions

Energy transactions often involve coordination across multiple parties, including investors, tax advisors, legal counsel, and auditors.

Marshall & Stevens provides independent valuation analyses that help align these stakeholders by:

This role is especially important in repowering transactions, where qualification for tax credits depends on how value is measured and allocated.

How do renewable energy incentives impact valuation in this sector?
Accordion Icon

Federal and state incentives—such as investment tax credits (ITC), production tax credits (PTC), and renewable energy credits (RECs)—play a significant role in determining project economics and valuation. Properly analyzing and monetizing these incentives is critical for structuring transactions and supporting defensible valuations.

Why is specialized expertise required for energy and infrastructure valuations?
Accordion Icon

Energy projects are highly capital-intensive and often financed through complex structures such as tax equity investments, leases, and sale-leasebacks. These transactions require detailed analysis of cash flows, regulatory frameworks, and asset performance to produce independent valuation opinions that meet accounting, tax, and investor requirements.
