Efficiency Works - Business Energy Efficiency Rebate Program (Offered by 4 Utilities)

Efficiency Works is a commercial/industrial rebate program offered by four Colorado utilities (Estes Park, Fort Collins, Longmont, and Loveland), not a residential program for homeowners.

Efficiency Works incentivizes energy efficiency upgrades for commercial and industrial customers, including lighting retrofits, LED fixtures, ENERGY STAR appliances, food service equipment, windows, insulation, VFDs, and EV charging infrastructure. Projects with rebates exceeding $10,000 require pre-approval before work begins, and you must submit a project invoice, signed W9, and completed application with terms and conditions agreement; incentive levels and limits vary by utility and are subject to change.

Efficiency Works is administered across four municipal utilities in Colorado (Estes Park Power and Communications, Fort Collins Utilities, Longmont Power & Communications, and City of Loveland Utilities) and targets commercial, industrial, and federal government sectors. The program funds rebates subject to availability with per-project and per-customer annual limits; projects exceeding $10,000 are capped at 100% of total project cost and require pre-approval. A Community Efficiency Grant offering an additional 100% of standard rebate (covering up to total project cost) is available through November 15, 2026 for nonprofit community service providers and income-qualified multifamily properties.
