ACS announces multi-year substation automation upgrade program for Sierra Pacific Power

Atlanta, GA, April 3, 2008 — Advanced Control Systems (ACS) announced that it has delivered several Connex 30 substation automation upgrade systems to Sierra Pacific Power. ACS delivered the systems as part of a multi-year contract that Sierra Pacific Power recently awarded to ACS following a competitive market evaluation. Sierra Pacific Power, the electric utility that serves most of northern Nevada and the Lake Tahoe area of California, plans to roll out ACS Connex 30 substation managers for all obsolete and new substation RTUs.

Sierra Pacific Power personnel use the ACS Connex Explorer configuration software to replicate the original substation database and minimize master system changes. Installation engineers leverage installed I/O points to upgrade each legacy substation RTU. ACS incorporates data concentrator functionality in the Connex 30 to support substation IED integration.
