NorthWestern Energy electric distribution customers may qualify for a rebate of $3,000 for the installation of a solar hot water system on their home. This program is administered by the National Center for Appropriate Technology (NCAT) using funds collected from NorthWestern Energy's electric customers as part of the NorthWestern Energy's Universal Systems Benefits (USB) program.

The new system serves as a pre-heater to the existing water heaters. While the systems won’t supply all hot water needs, they will substantially reduce energy use. System size and energy savings will vary according to family size and hot water usage. NCAT will specify the systems, which will be installed by contractors. The systems include solar collectors, associated plumbing, an additional water take and provide freeze protection allowing them to operate year-round. Participants in the solar water heating project must be active NorthWestern Energy electric customers, but water heaters may be gas or electric. NCAT will install equipment to monitor system performance.

Completed applications must be submitted to NCAT by April 4, 2003. Approximately 12 systems will be installed using 2003 funds.
