DSTAR-supported software enhances commercial transformer sizing

From the June 21, 2013 issue of Public Power Daily

Originally published June 21, 2013

APPA members are entitled to a three-month free trial of commercial load estimation software developed through the DSTAR (Distribution Systems Testing, Application and Research) program.  The software enables a utility to produce an accurate estimate of electrical load at a new or existing commercial facility so transformer sizing can be appropriate for the building. Utilities that have used the program have been able to reduce transformer sizes for commercial customers. 

The software, "iCLEAR" (Industrial and Commercial Load Estimating and Referencing system), was developed for Southern Co. by Z Solutions.  At the conclusion of the trial, utilities that use the software for three months can purchase a license from Z Solutions at a rate negotiated between DSTAR and Z Solutions.

APPA’s research program, DEED (Demonstration of Energy & Efficiency Developments), contributes money to DSTAR on behalf of all APPA-member utilities. DSTAR is a distribution research and development program supported by a consortium of utilities. General Electric Consulting manages the program for industry participants.

An article in the spring 2013 issue of the DEED Digest provides more information about the iCLEAR software. The DSTAR page of the DEED website provides detailed information about research undertaken by the DSTAR consortium.
