Feb 23, 2004 - SUBSTANTIAL COMPLETION OF FIRST COMMERCIAL NORTH AMERICAN VRB ENERGY STORAGE SYSTEM.
Vancouver, B.C. (February 23, 2004) - VRB Power Systems Inc. ("VRB Power") is pleased to announce the substantial completion of the first large scale North American commercial installation of a VRB Energy Storage System ("VRB-ESS") for PacifiCorp, in Castle Valley, Utah.
The project consists of a 250kW X 8-hour (2000kWh) VRB Energy Storage System connected to an 85 mile 25kV rural feeder. The system will be used primarily as a load-levelling (peak-shaving) device. The VRB-ESS will typically be charged during the evening or off-peak hours and discharged during peak and high demand periods so as to provide voltage support and power flow control to the distribution grid. The system will also provide voltage sag compensation and continuous power factor correction on the feeder.
Based in Vancouver, B.C. Canada, VRB Power Systems Inc. is an electrochemical energy storage company that has commercialized the patented Vanadium Redox Battery Energy Storage System ("VRB-ESS"). The VRB-ESS is a new enabling technology that can effectively store electricity on demand. The VRB-ESS can provide direct economic benefits to utilities and end users in terms of improved power quality, reliability and energy efficiency. The VRB-ESS is particularly well suited to load levelling (peak shaving), electrical power arbitrage, grid stability enhancements, capital deferment and Remote Area Power Supply (RAPS) applications.
