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.
