Arevon Energy signs 20-year REC contracts with three Illinois utilities for 200 MW Panther solar project in Perry County
Arevon Energy announced on October 13, 2026, that it signed three separate 20-year Indexed Renewable Energy Credit contracts for its 200 MWac Panther Energy Project in Perry County, Illinois. The agreements went to three of the state’s major utilities: Ameren Illinois, Commonwealth Edison, and MidAmerican Energy.
Arevon executes three long-term REC agreements for Panther Energy Project
The Panther Energy Project carries a capacity of 200 MWac and 275 MWdc. That distinction matters — the DC rating reflects total panel output, while the AC rating is what actually flows onto the grid. At those specs, Panther lands squarely in utility-scale territory.
Arevon picked Perry County in southern Illinois as the site. Panther Energy was selected through the Illinois Power Agency’s Summer 2026 Indexed REC procurement, and the Illinois Commerce Commission formally approved that selection before the agreements could be signed. Each utility — Ameren Illinois, ComEd, and MidAmerican Energy — holds its own 20-year contract, spreading the project’s REC output across multiple counterparties rather than concentrating everything in a single deal.
Locking in long-term revenue streams gives developers like Arevon the predictability needed to secure project financing and move construction forward.
IPA procurement process and Illinois climate law underpin the contracts
The Summer 2026 procurement ran under Illinois’s Climate and Equitable Jobs Act — CEJA — which became law in 2021. That legislation established the Indexed REC pricing framework specifically for utility-scale renewable procurements in the state. It didn’t come out of nowhere; it was a deliberate policy architecture designed to move large projects forward.
Under the IPA’s methodology, Panther Energy was selected to deliver 421,131 RECs in the first contract year, divided among Ameren Illinois, ComEd, and MidAmerican through their individual agreements with Arevon. Panther wasn’t the only project approved in this round — the ICC greenlit contracts for 1.55 gigawatts of new renewable capacity in total, including four utility-scale solar projects adding up to 740 MWac.
Construction timeline, jobs, and economic impact for Perry County
Arevon plans to break ground on Panther in 2027, with completion targeted for 2028 — roughly a two-year build window that’s standard for a solar project at this scale. During construction, the project is expected to create around 200 jobs, which carries real weight in a rural county like Perry.
The longer-term numbers are also worth paying attention to. Arevon estimates the project will generate approximately $20 million in property tax payments over its operating life, flowing to local schools, infrastructure, and public services. Once the panels are running, Panther is projected to produce enough electricity to power more than 37,000 Illinois homes.
Indexed REC structure provides revenue certainty and supports Illinois renewable targets
The Indexed REC model functions as both a procurement mechanism and a financing tool. Locking in long-term revenue streams gives developers like Arevon the predictability needed to secure project financing and move construction forward. For the utilities, the calculation works differently — the RECs acquired through these contracts count toward obligations under the Illinois Renewable Portfolio Standard, the state’s mandate requiring utilities to source a growing share of electricity from renewables.
Arevon also opened a local office in Pinckneyville, the Perry County seat. That office gives landowners, residents, and local officials a direct line to the project team during development and construction — an approach that tends to reduce friction with communities hosting large energy infrastructure.
Arevon’s broader Midwest solar portfolio and recent milestones
Panther fits into a larger pattern of Midwest expansion for Arevon. The company recently brought its 430 MWdc Kelso Solar Project in Missouri online. In Indiana, operations started at the Ratts 1 and Heirloom Solar Projects, which together total 264 MWdc and earned the 2025 Proximo North America Solar Deal of the Year.
Closer to home, Arevon is nearly done with construction on the 124 MWdc Big Muddy Solar Project in Jackson County, Illinois. The company has also developed and managed construction of the 251 MWdc Gibson Solar Project and the 228 MWdc Posey Solar Project on behalf of local Indiana utilities — work that shows a range extending well beyond self-developed assets.
What the Panther project means for Illinois energy
The three 20-year contracts represent a significant commitment from both sides. Arevon is locking in decades of revenue tied to a project that won’t generate power until 2028 at the earliest, while the three utilities are committing to long-term REC purchases that support their compliance with state renewable mandates. Neither party is making a short-term bet.
For Illinois, the deal advances CEJA’s goals by adding 200 MWac of new solar capacity to the grid, delivering local jobs and tax revenue to Perry County, and distributing the project’s renewable output across three of the state’s major utility providers. It’s a deal structure that threads multiple policy objectives at once.
