The U.S. Department of Energy and the North Carolina Clean Energy Technology Center are excited to announce that a new, modernized DSIRE is under construction. The new version of DSIRE will offer significant improvements over the current version, including expanded data accessibility and an array of new tools for site users. The new DSIRE site will be available in December 2014. Staff are currently working hard on the new version of DSIRE but are also maintaining the content of the current version of DSIRE. Thank you for your continued support and patience during this transition. We hope you are as excited for December as we are!

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.

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 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.
