Illinois published final guidelines on Sept. 10 for its Equitable Energy Upgrade Program, the first framework under the Climate and Equitable Jobs Act enabling utilities to finance customer energy upgrades with no upfront cost or credit check. Analysts say pairing this model with virtual power plants could address both affordability and grid flexibility gaps.
Illinois has published final guidelines for its Equitable Energy Upgrade Program, the first framework of its kind under the state’s Climate and Equitable Jobs Act, enabling utilities to directly finance residential solar, storage and other flexible energy assets at customers’ homes without upfront costs, credit checks or homeownership requirements. Writing in Utility Dive, Zuha Maryam Shaikh, deputy director of market innovation at Clean Energy Works, argues the program could make Illinois the first state to demonstrate what pairing inclusive utility investment with virtual power plants can achieve — a combination meant to lower bills while easing grid strain.
The program works through a mechanism called inclusive utility investment: a utility pays for distributed energy resources installed at a customer’s home or business and recovers its capital through a fixed monthly charge on the customer’s bill. By design, that charge is less than the estimated bill savings the upgrades produce, so the customer sees a lower bill from day one. Site-specific cost recovery charges cannot exceed 80% of a customer’s estimated savings from the energy system, according to the program framework.
The economics are substantial in Illinois. A typical 7-kW solar and 13.5-kWh storage system carries an upfront cost of about $34,530, reduced to an $11,913 financing gap after utility-program rebates — a gap the program allows the utility to cover directly. Once enrolled in a virtual power plant, the same system could generate roughly $770 per year in additional revenue from PJM Interconnection capacity, energy arbitrage and ancillary services markets, split between the household and the utility, according to Shaikh’s analysis.
The program arrives amid broader state-level momentum. According to Canary Media figures cited in the piece, 34 states have programs directing utilities to use distributed energy resources to address rising electricity prices, and at least a dozen states — including Illinois and Virginia — are considering or have passed legislation to launch or expand virtual power plants. Illinois’ Clean and Reliable Grid Affordability Act reflects that same recognition of virtual power plants as an affordability and reliability tool as demand and renewable penetration grow.
Why Access Gaps Block Grid Flexibility
The core problem the program targets is participation. As of 2026, roughly 28% of U.S. homes have smart thermostats, but the share enrolled in any utility demand response program is far lower — and for electric vehicles, chargers and batteries, participation drops steeply, according to the analysis. Currently, only customers who already own distributed energy resources, or who can pay for them with their own cash or credit, can take part.
Shaikh writes that upfront cost barriers deter tens of millions of renters and homeowners, limiting the number of flexible devices available to virtual power plants. That means the critical mass of devices needed to deliver meaningful grid flexibility cannot be reached, despite more than half of U.S. states pursuing planning, pilots or implementation. She frames this not only as an equity issue but as a roadblock to state grid flexibility and affordability goals.
Because virtual power plants are cheaper and faster to deploy than new peaker plants and transmission lines, broader participation could limit base-rate increases for all customers — including those who never enroll a device. A May 2026 analysis from Rewiring America, the Homegrown Energy report, found that under current market conditions home energy upgrades are affordable for fewer than one in ten U.S. households, and identified inclusive utility investment among the highest-priority policies in a six-policy package to extend access.
How Illinois Built the Framework
: “The Climate and Equitable Jobs Act, Illinois’ sweeping energy law, provided the statutory foundation for the Equitable Energy Upgrade Program. The final guidelines published September 10 represent the first framework of its kind under that law, and authorize expanded deployment of residential solar, storage and other flexible assets through the inclusive utility investment mechanism.
Under the program’s structure, once a utility recovers its costs — with an embedded cost of capital plus a share of virtual power plant revenue and the value of deferred or avoided infrastructure — ownership of the system automatically transfers to the building owner. For customers, virtual power plant revenue can be applied toward their cost recovery charges, accelerating payback for both the household and the utility.
“Utilities know that they cannot build new poles and wires fast enough to meet the growing power demand.”
— Zuha Maryam Shaikh, deputy director of market innovation at Clean Energy Works, writing in Utility Dive
Questions the Illinois Pilot Must Answer
Several outcomes remain unproven. The claim that pairing inclusive utility investment with virtual power plants accelerates utility cost recovery and delivers greater customer benefits is an analytical projection, not yet demonstrated at scale. The $770 annual revenue figure depends on PJM market conditions, which fluctuate. It is not yet clear how many Illinois utilities will adopt the program, how quickly enrollments will scale, or how renters — a population often excluded from such programs — will be reached in practice. The long-term bill impacts for non-participating customers also remain to be measured.
Enrollment Rollout and State Watchers
Attention now turns to implementation: Illinois utilities are expected to begin deploying upgrades under the finalized Equitable Energy Upgrade Program guidelines, with early enrollees testing whether bill savings, cost recovery and virtual power plant revenue perform as modeled. Other states pursuing virtual power plant legislation — including Virginia — may watch Illinois’ results as a template. Broader adoption of the six-policy package outlined in Rewiring America’s Homegrown Energy report, and the pace of federal and state support for distributed energy, will shape whether the approach spreads beyond early movers.
Key Questions
What is inclusive utility investment?
It is a financing model in which a utility pays upfront for energy upgrades — such as solar panels, batteries or efficient appliances — at a customer’s home or business, then recovers the cost through a fixed monthly charge designed to be smaller than the estimated bill savings. Customers face no upfront cost, credit check or homeownership requirement.
What is a virtual power plant?
A virtual power plant aggregates many distributed energy resources — like home batteries, EV chargers, water heaters and smart thermostats — and coordinates them to reduce or shift electricity use, or feed power back to the grid, in exchange for compensation. Customers are often paid for lowering or deferring energy use without actively managing their devices.
Why can’t more households participate today?
Participation generally requires already owning flexible devices or having the cash or credit to buy them. As of 2026, about 28% of U.S. homes have smart thermostats, with utility program enrollment much lower, and far fewer have EV chargers or batteries. Upfront costs deter tens of millions of renters and homeowners, limiting the pool of devices available to virtual power plants.
How does Illinois’ Equitable Energy Upgrade Program work?
Under final guidelines published September 10, utilities can cover the remaining financing gap for a home energy system after rebates — about $11,913 for a typical 7-kW solar and 13.5-kWh storage setup in Illinois — and recover costs through monthly charges capped at 80% of the customer’s estimated savings. Ownership transfers to the building owner once costs are recovered.
Could this model lower bills for customers who don’t participate?
According to the analysis, yes in principle: virtual power plants are cheaper and faster than building new peaker plants and transmission lines, so broader participation can reduce or defer costly infrastructure upgrades, limiting base-rate increases for all customers. However, the size of those savings has not yet been demonstrated at scale.
