But for clean energy and environmental advocates, the Naperville city council results represent an encouraging, if overlooked, victory. On Tuesday, voters in the suburb elected four candidates — incumbents Benjamin White and Ian Holzhauer, and newcomers Mary Gibson and Ashfaq Syed — all of whom oppose the city signing a new contract with the Prairie State Generating Station, the state’s largest and youngest coal-fired plant and the seventh-dirtiest electricity provider in the country.
Naperville is one of 30 municipal investors in the Prairie State plant whose contract with the Illinois Municipal Electric Agency, a public power agency and one of the nine partial owners of Prairie State, has it locked into coal through 2035. Recently, IMEA approached the municipal investors with the promise of favorable terms on a new contract if the cities and towns were willing to re-sign a decade early — by April 30 — and commit to another 20 years of coal power. Most municipalities took the deal, which will run through 2055; Naperville, along with the towns of St. Charles and Winnetka, are still debating the decision, with the deadline looming.
“IMEA’s proposition for communities is, ‘Hey, instead of paying Wall Street and shareholder dividends, we don’t have any of that because we’re a nonprofit, so you get lower energy costs,’” Fernando Arriola, the community relations chair for Naperville Environment and Sustainability Task Force, which opposes the deal with IMEA, told me. “But the way I look at it is, it’s a deal with the devil because you’re locked in for 30 years. And it’s like Hotel California — you can check in anytime you like, but you can never leave.”
In a statement to Heatmap, Staci Wilson, the vice president of government affairs and member services at IMEA, told me that the contract it offered to Naperville is “designed to help … secure more future green resources to serve our member communities for the long term. IMEA is the only power supplier to allow the city to have a direct voice in procuring their wholesale power supply and make reliable, economical, and sustainable resource decisions for the future.”
While it’s true that IMEA allows its municipal members a voice in its future planning, those in Naperville who oppose the new contract point out that the community has just one vote in the process despite making up 35% of the utility’s market.
The pending contract decision became one of the major themes of the city council race in Naperville — attention that caused some locals to grumble about the injection of partisan politics and outside interest in the campaigns. But Syed, a newly elected city council member and a recent immigrant from Dubai, told me that learning that his city relied on coal for 80% of its energy needs was what ultimately galvanized him into running. “Naperville has been a leader in many things, but in this area, we were not doing good,” he said. “So I stepped up.”
Illinois has one of the nation’s most aggressive decarbonization timelines, requiring coal and gas plants to close by 2030. But there is a carve-out for plants owned by public entities like municipal utilities or rural electric cooperatives, and Prairie State fits that bill. Instead, the power plant has to reduce emissions by 45% by 2038, a goal IMEA says it can reach by installing multi-billion dollar carbon capture and storage technologies. Energy experts have been widely skeptical of the proposal. “The people I’ve talked to say that’s unproven and it doesn’t necessarily work, and it’s a high price,” Arriola said.
Still, cost concerns related to transitioning away from coal had “definitely been a conversation in town” leading up to Tuesday’s election, Arriola told me. “A lot of people are seriously concerned about pricing, and there are also concerns about the reliability.” Syed told me that was one of the objections he heard the most when talking to constituents during his campaign. “Some of the Republicans who were against [exporing alternative energy options] were trying to influence people, saying we need to think about the cost,” he said. “My standard answer to these people was that I am not going to compromise clean energy just for the cost purpose.”
Perhaps most interestingly, unlike many communities that oppose power plants, Naperville is located almost 300 miles north of the Prairie State Generating Station and is unaffected by its immediate pollution. Naperville voters who opposed renewing the contract did so on the merits of finding cleaner energy sources and on the objection to dirty electricity that is otherwise out of sight and out of mind. As Amanda Pankau, the director of energy and community resiliency at the Prairie Rivers Network, an environmental nonprofit in the state, told me, “From a climate perspective, we should all care about the Prairie State coal plant.” She noted that the emissions from the plant — around 12.4 million tons of carbon dioxide a year — are “impacting every single Illinoisan and every single person that lives on planet Earth.”
Despite those existential stakes, it could be tempting to wave away the results in Naperville as being on trend for a relatively affluent and liberal-leaning town. Compared to the Wisconsin supreme court election, where the Democrat-backed candidate overcame enormous spending margins to trounce her Republican-backed opponent, it does not necessarily indicate the same momentum for the party heading into 2026’s midterms. (Nor does it even have the biggest climate-related election headline of the night: Tesla is suing Wisconsin for a law preventing car manufacturers from owning car dealerships, which the state’s high court will likely decide.)
But at a time of little good news in the climate sphere, the Naperville election is an encouraging and invigorating reminder that there are candidates who believe in cleaner technologies, and that the battles can still — or especially — be won at the local level. “Twenty-five or 30 years ago, the IMEA contract we signed for that time was okay,” Syed said. “But it’s not okay today. We cannot have this $2 billion contract until 2055 because the next generation will ask us this question: ‘What have you people done for us this time?’”
