Cascade Natural Gas - Commercial Efficiency Rebate Program

August 16, 2024

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.
