Cascade Natural Gas - Commercial Efficiency Rebate Program
Administered by Lockheed Martin Energy and Environmental Services
Cascade Natural Gas offers cash rebates for commercial and industrial customers who upgrade to high-efficiency equipment like furnaces, boilers, water heaters, HVAC systems, and building insulation—you must be on one of their qualifying rate schedules (504, 505, 511, 570, or 577) and use natural gas as your primary heat or water heat source. To apply, download the incentive request form from their website, work with a qualified trade ally contractor, and submit your application along with equipment quotes, paid invoices, and manufacturer specifications by calling 866-450-0005 or emailing the program. Incentives increased as of March 15, 2026, and custom projects not on the standard list may also qualify if cost-effective.
Cascade's Commercial Efficiency Rebate Program helps your commercial and industrial customers offset energy upgrade costs through rebates on standard equipment categories (heating, hot water, weatherization, food service) and custom measures—you should join their Trade Ally Directory to gain visibility and access to program resources and requirements. Qualifying projects must involve equipment that provides significant efficiency gains over existing systems, and you'll need to help customers gather documentation including W9 forms, recent gas bills, quotes, and paid invoices to ensure smooth rebate processing.
The program delivers cash incentives to commercial and industrial customers on rate schedules 504, 505, 511, 570, and 577 in Washington, targeting natural gas consumption reduction through standard and custom rebate offerings across heating, water heating, weatherization, and food service categories. Applications are submitted online or via fax/email with supporting documentation (quotes, paid invoices, manufacturer specs, W9, recent gas bills), and the program prioritizes projects demonstrating significant efficiency improvements and cost-effectiveness; as of March 15, 2026, many incentive levels increased to drive higher participation among small-to-large commercial and industrial facilities.

Program summary
Cascade Natural Gas Corporation's conservation program provides cash incentives for the installation of energy efficiency technologies. Customers can download an incentive request form from the utility's website and send it to the email address or fax number listed below. Incentives not included in the standard list may still be eligible for an incentive reward through the custom program if the project is determined to be cost-effective. Standard incentives are available to commercial and industrial customers on Rate Schedules 504, 505, 511, 570, and 577.
Incentives are only valid if the new equipment provides a significant efficiency increase over existing equipment. Customers requesting site-specific energy efficiency measures must submit estimated costs and natural gas savings associated with the project. To receive a conservation incentive, customers should provide an incentive request form, W9 Form, copy of a recent gas bill, quote for proposed equipment, final invoice marked “Paid,” and a manufacturer’s specifications sheet.
