The Missing Middle in Clean Energy Finance
Global renewable energy investment hit record levels in 2024. But if you look at where the capital in clean energy finance actually flows, the picture is less encouraging for most developers: utility-scale mega-projects with hundreds of megawatts attract institutional money almost automatically, while projects in the 1–20 MW range struggle to close rounds at all.
This is what practitioners call the "missing middle"—a segment that generates real power, serves real communities, and has real offtake agreements, but can't easily access the capital markets designed for either end of the spectrum.
Why Small and Mid-Sized Projects Struggle to Raise Money
Before getting into what tokenization does, it's worth being precise about why the current approach to renewable energy project financing fails this segment specifically.
Transaction costs don't scale down. Legal fees, due diligence, structuring costs—these run roughly the same whether you're raising $5 million or $50 million. A solar project generating $800,000 a year simply can't absorb the same upfront capital-raising overhead as one generating $8 million.
Illiquidity is a structural deterrent. Energy assets lock capital in for 10–15 years. Institutional investors can model that and price it. But retail investors who might otherwise be interested have no mechanism to exit early if their circumstances change.
No standardization across deals. Every small renewable project is structured slightly differently—different legal wrappers, different offtake structures, different jurisdictions. That fragmentation makes it nearly impossible to compare projects or package them into portfolios, which keeps aggregators and fund managers away.
What Tokenization Actually Means Here
Strip away the noise and it comes down to one thing: renewable energy tokenization means representing a stake in a project—or in its revenue stream—as a digital token on a blockchain.
That stake can take different forms, and the distinction matters:
Debt tokens represent a loan to the project. Investors receive fixed interest payments and principal repayment. Simpler to structure legally in many jurisdictions, lower risk for investors, but no upside participation.
Equity tokens represent fractional ownership. Token holders share in the project's value and potentially in governance. Higher potential return, more complex compliance requirements, more aligned incentives with the developer.
Revenue tokens represent a claim on future cash flows—typically a percentage of PPA receipts or electricity sales—without formal equity ownership. Closer to a royalty structure. Useful in jurisdictions where equity crowdfunding is restricted.
How Tokenization Closes the Gap—A Developer's View
Each of the structural problems above has a direct answer in a well-designed token structure.
Fractional ownership lowers the minimum ticket. Where a conventional deal might require something like $25,000 to participate, a tokenized project can, in principle, accept checks as small as a few hundred dollars. That opens the investor base from a few dozen institutions to potentially thousands of retail participants.
Smart contracts reduce administrative overhead. Distributions to hundreds or thousands of investors that would require significant manual processing get handled automatically by the contract logic.
Speed of issuance compresses. A traditional private placement for a mid-sized renewable project can take many months to structure and close. Token issuances on regulated platforms have, in some cases, closed far faster—in a matter of weeks.
Standardization makes projects comparable. Platforms that tokenize multiple projects necessarily impose a common structure—due diligence format, disclosure standards, token mechanics. That standardization is a side effect that benefits the whole ecosystem: it makes small projects legible to investors who want to build diversified portfolios across multiple tokenized renewable energy assets.
Case Studies: What Works and What Doesn't
Theory is useful. What happened in practice is more instructive.
Enel and Conio (Italy)—Regulatory-First Approach
In January 2025, European energy giant Enel, in partnership with fintech firm Conio, launched a tokenization product in Italy on the Algorand blockchain under its EBITTS program, with tokens colloquially known as "Energy Utility Tokens."
It's important to be precise about what these tokens actually do, because it's easy to misread them as an investment product. They aren't one. A holder buys fractional ownership of utility-scale solar and wind assets, and the energy that their share generates is used to offset their own electricity bill; if their share produces more power than they consume, Enel credits the excess. In other words, the "return" is reduced electricity costs through self-consumption—not a cash distribution, a yield, or a share of revenue. This is what lets Enel structure the instrument as a utility token rather than a security.
That distinction is exactly why the case is instructive for developers, even though it isn't a financing deal in the strict sense. Two lessons stand out.
First, methodology. Enel built the product around the regulatory framework rather than looking for a gap in it. The structure is aligned with the EU's MiCA regime, and the choice of a consumption-based utility token—instead of a revenue or equity token—was a deliberate way to stay outside securities classification while still offering retail participation at small ticket sizes. For a smaller developer, the takeaway isn't to copy the utility-token route (most financing deals genuinely are securities and should be treated as such), but to decide the regulatory posture first and design the token to fit it.
Second, the access point. Even a company with Enel's balance sheet and existing customer base used tokenization specifically to bring ordinary retail participants into renewable assets at fractions most of them could never buy directly. In Europe alone, more than 85 million households live in apartments with limited ability to install panels on their own roofs—that's the audience the structure is designed to reach. The mechanism scales down to the individual; the lesson is that it can.
The Sun Exchange (South Africa)—What Failure Looks Like
The Sun Exchange model was genuinely innovative: retail investors could buy individual solar cells for a small amount, on the order of $10 each, and lease them to schools and businesses across South Africa, receiving returns in fiat or Bitcoin. For several years it worked.
In 2024 the platform shut down its crowdsale model. What went wrong is worth examining carefully because the problems were structural, not cosmetic.
First, the crowdsale model was tied to crypto market sentiment. As the crypto cycle turned down from 2022 onward, retail appetite for this kind of product dried up while institutional financing for similar assets was growing.
Second, the project pipeline evolved toward larger, more complex assets—projects with battery storage, higher capital requirements, slower deployment cycles. The crowdsale mechanism that works for a $50,000 school rooftop install doesn't work well for a $2 million commercial facility with a storage component.
Third, and most damaging to investor trust: when the platform sold its project portfolio to investment company Jaltech, investors reported that assets were sold without their consent—in a number of cases at around two-thirds of invested value—and that the income received during the investment period hadn't made up the difference.
Risks and What to Get Right
Developers considering tokenization as a financing tool need to be clear-eyed about where the real risks sit.
Regulatory classification is not optional. In most meaningful markets, a token representing a financial return on an investment is a security. That means securities law applies—registration requirements, disclosure obligations, investor protections. MiCA in the EU, Regulation D and broker-dealer requirements in the US, equivalent frameworks elsewhere.
The underlying asset has to perform. Tokenization doesn't improve a bad project. It makes a good project accessible to more investors. Due diligence on the asset—resource assessment, offtake counterparty credit, technology risk, developer track record—is just as important in a tokenized deal as in a conventional one.
Liquidity needs to be real. A low minimum ticket is only half the promise—the other half is not freezing capital for the asset's full life. The most reliable liquidity here isn't an early exit but the cash flow itself: a well-structured debt or revenue token pays out on a regular schedule, and smart contracts make frequent distributions cheap even across thousands of small holders, so investors aren't waiting years with nothing in hand.
Where an actual exit is needed before maturity—resale or an issuer buyback—it shouldn't be oversold: trading infrastructure is still thin, and a token that can be transferred isn't one that can be sold quickly at a fair price. The Sun Exchange episode is the cautionary version: when demand dried up and no real exit existed, investors had assets sold from under them at a fraction of value. Designing credible cash flows from day one is one of the highest-leverage things a developer can get right.

Conclusion: A Tool, Not a Silver Bullet
Tokenization won't replace project finance. The largest renewable energy projects will continue to be financed by banks, infrastructure funds, and institutional capital using conventional instruments—and that's appropriate given the scale and sophistication of those transactions.
But for the 1–20 MW segment that currently falls between the cracks, tokenization for renewable energy projects offers something genuinely useful: a way to reach the retail investors who want to participate and currently can't, at a cost structure that makes smaller projects viable to capitalize.
