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!

NSTAR Gas offers incentives for their commercial customers to save energy in existing facilities. Rebates are for high efficiency gas space heating equipment, water heating equipment, infrared heating equipment, and commercial cooking equipment. All equipment must meet energy efficiency standards listed on the program web site. Equipment incentives may vary based upon the rated efficiency of the unit. Incentives are available on a first come, first served basis.

The Custom Program allows commercial customers to save energy with a variety of high efficiency gas technologies. NSTAR Gas will pay up to 50% of the project cost for qualifying projects.
