Engineering-Led Solar and Battery Storage for Naperville, IL Facilities.
General Energy Corporation has designed and installed commercial solar across Illinois for 40+ years. Licensed P.E.s, full EPC under one roof, every incentive captured project by project: the 30% federal Investment Tax Credit, the $250/kW ComEd inverter rebate, and Illinois Shines SREC revenue.
ComEd's 2026 capacity charge restructure is hitting DuPage County harder than most operators expected. Naperville facilities are seeing demand charges climb 15 to 25 percent before a single kilowatt-hour of usage changes, and the cost stack is going to keep moving until you do something about it.
Three deadlines are converging in Naperville in 2026.
Three deadlines are converging for Naperville businesses considering commercial solar in 2026.
The federal Investment Tax Credit (Section 48E) is available now at 30 percent for qualifying commercial solar projects in Naperville, but Foreign Entity of Concern compliance rules taking effect raise project costs 15 to 20 percent for systems that source components from restricted suppliers. Projects safe-harbored before July 4 lock in today's pricing and the credit value.
ComEd's restructured capacity charge framework went live in 2026 and has hit commercial customers harder than most expected. The bills now reward facilities that can shave peak demand, which is exactly what battery storage is engineered to do.
Illinois Shines, the state's SREC program, is operating in a high-payment block right now. New commercial solar systems registered in 2026 are earning roughly 34 to 43 percent more per SREC than 2024 vintages, but block capacity fills in waves and the program economics shift each cycle.
The window is real. The question is whether your facility captures it or watches it close.
Four programs, fully stackable, modeled together.
Commercial solar and battery storage in Naperville, Illinois currently qualifies for four stackable incentive programs. For most C&I facilities, the combined offset runs 40 to 90 percent of total project cost before financing.
Federal Investment Tax Credit (Section 48E)
30% direct credit on total system cost for qualifying commercial solar projects. Transferable to third-party tax buyers if your facility lacks the tax appetite to absorb the full credit. GEC structures the capture and handles all required documentation.
ComEd Distributed Generation Rebate (Inverter Rebate)
$250 per kW DC of solar capacity in ComEd territory. Paid as a direct cash check after commissioning, fully stackable with the federal ITC. A 500 kW commercial system earns a $125,000 utility check; a 1 MW system earns $250,000. First-come-first-served from a limited annual pool.
Illinois Shines SREC Program
Annual revenue from Solar Renewable Energy Credits issued for every megawatt-hour of generation. 2026 vintage SRECs are paying 34 to 43 percent more than 2024 levels for commercial-scale projects, creating a 15-year revenue stream alongside the direct energy savings.
MACRS Accelerated Depreciation
5-year accelerated depreciation schedule on the full system basis. For most C&I taxpayers this recovers an additional 20 to 26 percent of project cost over the depreciation window, layered on top of the ITC and utility incentives.
40 years of Illinois engineering, 30 minutes from the I-88 Corporate Corridor.
General Energy Corporation has been engineering commercial energy systems for Illinois businesses since 1985. Our corporate office sits in Schaumburg, roughly 30 minutes from Naperville's I-88 Corporate Corridor, with licensed professional engineers, in-house procurement, and our own construction teams. We deliver full EPC services under one roof: engineering, procurement, and construction, so your project does not get fragmented across a coordination layer and three subcontractors.
Across 200+ commercial solar installations and 500+ C&I clients, GEC has delivered measurable results for energy-intensive facilities: $434,406 in annual savings for a specialty textiles manufacturer, $316,823 for a Fortune 500 food and beverage operation, $231,725 for an auto parts powertrain plant. Same engineering rigor, applied to Naperville.
Tech, professional services, healthcare, and light-manufacturing operations across Naperville Corporate Center, Naperville Office Park, Naperville Woods Office Center, the I-88 High-Tech Corridor, and the Fort Hill industrial district share two things: high baseload electrical demand, and bills that are about to keep getting worse. The cost of doing nothing is no longer flat.
What GEC delivers for Naperville facilities.
What GEC's engineering and construction teams deliver for commercial and industrial facilities in Naperville, Illinois:
Commercial Rooftop Solar
Structural assessment, system design, procurement, and installation, all in-house. Typical Naperville commercial rooftop systems range from 100 kW to 2 MW depending on roof area, load profile, and electrical infrastructure.
Battery Storage and Demand Charge Reduction
Peak-shaving systems sized to your specific ComEd demand profile. Standalone or solar-paired. Targets 20 to 40 percent reduction in monthly demand charges plus backup capacity for critical loads.
Incentive Capture and Tax Credit Optimization
We model the full incentive stack across federal ITC, Illinois Shines SREC, ComEd rebates, and MACRS depreciation, and structure the project to capture every dollar your facility qualifies for. Tax credit transferability handled directly where it makes sense.
Energy Conservation Measures (ECMs)
LED retrofits, high-efficiency HVAC and chiller upgrades, building automation, compressed air optimization, and process electrification. Same engineering team that handles solar, bundled where the economics align.
Project Financing Structuring
Direct purchase, PPA, lease, and tax credit transfer paths. We model each option against your cap-ex appetite, tax position, and balance sheet preferences before recommending a structure.
Compliance and Reporting Documentation
Scope 2 emissions documentation, ESG reporting support, and customer-facing sustainability narrative for facilities serving large CPG, retail, or institutional customers with their own decarbonization commitments.
