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 if the project is determined to be cost effective.

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 cash conservation incentive, customers should provide an incentive request form, W9 Form, copy of recent gas bill, quote for proposed equipment, final invoice marked “Paid,” and a manufacturer’s specifications sheet.

Cascade Natural Gas also allows cost-effective custom projects for facilities which include buildings on both Residential Rate Schedule 503 and commercial qualifying Rate Schedules 504, 505, 511, 570 and 577 as part of the same CNGC customer account. Contact Cascade for more information.
