MidAmerican Energy - Illinois Business Programs and Rebates
Administered by MidAmerican Energy Company
MidAmerican Energy's Instant Discounts program provides automatic rebates on energy-efficient equipment like heat pumps, boilers, lighting, and food service equipment for Illinois nonresidential customers—discounts are deducted at purchase, so no paperwork is needed. Incentive amounts vary by technology and size (for example, geothermal heat pumps offer $900–$1,200/unit, while LED lighting retrofits range from $1.50–$3.50 per unit), and equipment must be purchased, installed, and operating between January 1 and December 31, 2026. To qualify, work with a participating Instant Discounts provider, ensure your equipment achieves at least 30% energy savings where applicable, and confirm your specific model meets program qualifications.
As an Instant Discounts provider, you can attract customers by offering point-of-sale discounts on a wide range of qualifying equipment across HVAC, lighting, food service, and agriculture categories without requiring customers to handle rebate paperwork. Specific incentive amounts are listed for each technology tier (for instance, small air-source heat pumps receive $300–$563/unit, while ductless splits are $375/unit), and you must stock equipment meeting MidAmerican's efficiency standards and ensure installations occur within the 2026 program window. Participating distributors can be listed on MidAmerican's Find a Contractor search tool, and Trade Allies should contact their Trade Ally Ambassador to enroll as a provider.
The Instant Discounts program provides point-of-sale rebates funded by MidAmerican Energy to nonresidential customers (commercial, nonprofit, schools, agricultural, industrial, and institutional facilities) in Illinois, with incentives varying by equipment type and size and distributed on a first-come, first-served basis through participating distributors. Equipment must be purchased and installed between January 1–December 31, 2026; lighting projects require 1,000+ annual operating hours and 30% minimum wattage reduction, while one-for-one lighting replacements only qualify (redesigns go to Nonresidential Energy Solutions). Customers cannot combine Instant Discounts with other MidAmerican programs, and equipment not listed in the standard program may qualify for custom rebates through Nonresidential Energy Solutions with preapproval.

Program summary
MidAmerican Energy offers a variety of energy efficiency rebate programs to nonresidential customers located in Illinois. The amount of the rebate varies greatly depending on the technology, its size and efficiency. Brochures that contain the details of rebate amounts and a rebate application can be accessed via the web site above.
Rebates must be submitted within three months of equipment installation in existing buildings and within six months of equipment installation in new construction. An itemized and dated invoice from the contractor must accompany the equipment application and must include details about the sizes and efficiency of all equipment. MidAmerican Energy also offers a custom system rebate for projects that improve energy efficiency but may not fit into the prescribed rebate programs.
MidAmerican Energy also offers the Small Business Express program, which is a free on-site energy audit service for small commercial facilities. An energy specialist will give recommendations and have several energy efficient options ready to install during the visit. Audit applications are available from the Small Business Express Program website. The Non-Residential Energy Analysis Program and Commercial New Construction Program also provide incentives and no cost services to eligible non-residential customers.
