"Cotonou - The governments of the west African states of Benin and Togo plan to make costly improvements to the Adjaralla dam on the Mono River to boost their power supplies, a Beninese official said on Monday. The modernisation of the dam and its hydroelectric plant will cost about $162-million dollars and increase its electricity production for the neighbouring countries to an annual 326 gigawatt-hours (GWH), the source said. In 1998, Benin and Togo were plunged into power shortages affecting all sectors of their economies for several months because of drought that led to a fall in water levels in Ghana's Akosombo dam, the main source of supply for the two countries. The Adjaralla dam is about 40 years old and cannot make up for further shortfalls in supply, leading power authorities in Benin to warn that the risk of future shortages remains high. Experts from the two nations and representatives of international institutions agreed on the development plan last week, the source said. The modernisation work is scheduled to start in December. The Electricity Community of Benin, which manages supply to both countries, has forecast that demand will rise to 1 125 GWH in Benin and 983 GWH in Togo by 2010. They currently also obtain electricity from Ivory Coast. Electric power consumption in 2003 exceeded 570 GWH in both countries. - Sapa-AFP ____ Canada http://www.vrbpower.com/ 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. It is primarily focused on stationary power sources such as utility substations, commercial buildings, production facilities, telecommunication operations, cellular radio sites, and renewable resource generation such as wind farms - creating the ability to provide ""firm"" capacity. As a ""green"" technology, the VRB is characterized by the lowest ecological impact of all energy storage technologies and is unlike most other conventional energy storage systems that rely on toxic substances such as lead, zinc or cadmium.
