The Alliance (top left) and Vector (above left and right) natural gas pipelines were both completed in 2000 and in service in December. A new centralized North American Control Centre (top right) was established in Edmonton to operate a number of Enbridge pipeline and distribution systems. companies at the Chicago hub. The pipeline has capacity to deliver approximately 1.3 billion cubic feet per day. Enbridge is the lead operator for the Vector Pipeline, and has  a 45% interest. Vector extends approximately 550 kilometres (340 miles) from the Chicago hub to Dawn, Ontario, and delivers Western Canadian and United States gas to markets and storage in Ontario, Quebec, and the Midwest and Northeast regions of the United States. Initial capacity is approximately 700 million cubic feet per day. Enbridge participates in the natural gas midstream business through its 40% investment in Alberta-based AltaGas Services Inc. AltaGas’s assets include natural gas processing facilities, ethane and natural gas liquids extraction plant processing capacity, and AltaGas Utilities Inc., a gas distribution company serving over 90 Alberta communities. Enbridge has long been a leader in pipeline operation technologies — its Supervisory Control and Data Acquisition (SCADA) computer systems and technical support services are in demand globally. In recent years Enbridge has applied this technology to the safe, efficient operation of its numerous pipelines through a dozen different Control Centres. Beginning  in 2001, however, control of most of the Company’s pipeline systems is being consolidated at the Transportation Group’s  new North American Operations Control Centre in Edmonton. In 2000, the Company began the relocation of control centres at 11 locations to an expanded Control Centre in Edmonton. Included in the move is the control console for the Enbridge Consumers Gas distribution system, previously located in Toronto, and the controls for the recently completed Vector Pipeline. The moves were the result of an operational review of Enbridge’s control centres conducted last year, and advances in pipeline control technology that make it possible to safely operate pipelines from a single location. Pipelines are electronically monitored from the Operations Control Centre in Edmonton using the PROCYS TM pipeline control technology. Information is relayed back and forth between Edmonton and remote sites 24 hours a day, seven days a week using WAN (wide area network) system technology. The centre monitors and controls approximately 15,000 kilometres (9,000 miles) of liquids pipelines, 550 kilometres (340 miles) of large diameter natural gas pipelines, and 30,000 kilometres (18,000 miles) of natural gas distribution lines. Consolidating the Control Centres to a single location will save money while ensuring the safety and integrity of the pipeline and gas distribution systems. It is expected that 12 control consoles will be fully operational by the end of 2001. Natural Gas Midstream NEW CONTROL CENTRE HAS LONG REACH ENBRIDGE 2000 ANNU AL REPORT 9
