Arevon Energy has closed a $120 million tax equity commitment from Wells Fargo Bank for its 124-megawatt direct-current (MWdc) Big Muddy Solar Project in Jackson County, Illinois, adding a new financing milestone as construction advances toward a planned year-end 2026 start of commercial operations.
The October 27 transaction follows a $183 million debt package that Arevon announced in February. Together, the two announcements account for $303 million in financing commitments associated with Big Muddy Solar. However, that figure is substantially higher than the nearly $198 million investment previously reported for the project, and the publicly announced details do not establish how the figures relate to one another.
The distinction matters because the February package included a tax equity bridge loan alongside a construction-to-term loan and a letter of credit. The latest commitment allows Arevon to monetize project tax attributes, including depreciation and investment tax credits. Without a more detailed breakdown from the company, it remains unclear how much of the newly announced tax equity replaces or otherwise relates to financing already arranged for the project.
The transaction therefore marks more than another funding announcement: it highlights the different financial instruments supporting a utility-scale solar development as it approaches operation.
Financing figures leave the project’s capital structure unclear
Arevon has described Big Muddy Solar as an investment of nearly $198 million. Its February financing announcement disclosed a $183 million debt package, while the October announcement added the $120 million Wells Fargo tax equity commitment.
Those figures should not be treated as proof that the project has received $303 million in separate, incremental funding. The debt package’s inclusion of a tax equity bridge loan makes the relationship between the two transactions particularly important, but the available announcements do not provide enough detail to calculate the net amount of new capital or reconcile the financing with the reported investment figure.
Tax equity plays a distinct role in U.S. renewable energy finance. Investors provide capital in exchange for eligible tax benefits and other agreed economic returns associated with a project. A bridge loan can help cover a project’s financing needs before a longer-term tax equity investment closes.
In Big Muddy Solar’s case, Arevon says the Wells Fargo commitment will enable it to monetize depreciation and investment tax credits. The company has not publicly provided the full transaction structure, the allocation of proceeds or a revised total project cost in the October announcement.
Those details would help establish whether the latest commitment primarily replaces interim financing, supports a different portion of the project’s capital requirements or reflects another arrangement within the overall financing structure.
A power agreement is in place, but the buyer remains unnamed
Big Muddy Solar also has a long-term virtual power purchase agreement with an American multinational technology company, according to previously published project information. The purchaser has not been identified publicly in the project materials reviewed for this article, and the agreement’s duration and pricing terms have not been disclosed.
A virtual power purchase agreement differs from a conventional arrangement in which a buyer receives electricity directly from a particular generating facility. It generally uses financial settlements tied to an agreed price and a market reference price, while the electricity itself is sold into the wholesale market.
Such contracts can help renewable energy developers manage price exposure and establish a commercial framework for a project. However, the presence of a virtual agreement alone does not establish the project’s profitability or eliminate its exposure to market and operating risks.
Identifying the purchaser and understanding the agreement’s terms would provide a clearer picture of Big Muddy Solar’s commercial arrangements. Neither the October financing announcement nor the earlier public project information reviewed here supplies those details.
Project approaches its planned operating date
Arevon began construction on Big Muddy Solar in 2025. The company has said more than 250 workers contributed to construction and expects the facility to begin commercial operations by the end of 2026.
The project has a reported capacity of 124 MWdc, equivalent to approximately 95 megawatts of alternating-current (MWac) capacity. The distinction reflects the different ways solar-panel output and a plant’s AC generating capacity are measured; the two figures describe different points in the electricity conversion process.
Arevon expects Big Muddy Solar to generate enough electricity to power more than 24,000 Illinois homes annually. It also projects more than $12.6 million in property tax payments over the project’s operating life, which could support local schools, roads and other public services.
Those figures remain company projections rather than measured operating results. The October announcement does not provide a specific commercial-operation date, a construction-completion percentage or a detailed update on grid interconnection.
The facility is part of Arevon’s wider Midwest portfolio. The company has brought its 430-MWdc Kelso Solar Project in Missouri into operation and has begun operating the Ratts 1 and Heirloom solar projects in Indiana, which have a combined capacity of 264 MWdc. Arevon is also developing the 275-MWdc Panther Energy Project in Illinois, for which it has secured three 20-year renewable energy credit contracts.
Big Muddy Solar’s next milestone is its planned entry into commercial operation. Until then, the final schedule and the relationship between its reported project investment and announced financing commitments remain important details to clarify.
As investment in new electricity generation continues across the United States, other energy projects are advancing through different stages of development. In Texas, enCore Energy is pursuing final regulatory approval for its Upper Spring Creek uranium project, which would support the domestic nuclear fuel supply chain.
