Syncrude develops tar sands, aided by unique utility hookup
Many energy-intensive process industries are confronted with power supply and demand margins. Such is the case with Syncrude Canada Ltd., a refinery that is currently producing ca. 100,000 bpd from N. Alberta's oil-rich Athabasca tar sands. Syncrude mines the oil sands using huge draglines, each weighing more than 6000 tons and using close to 10 MW. When all 4 are operating, they create large surges in power demand, which can swing by 60 MW in less than 2 min. To meet the need for steam and electricity, Syncrude built a combined-cycle cogeneration power plant, consisting of a 60-MW condensing steam turbine, three 50-MW backpressure steam turbines, and two 25-MW gas turbines. The plant easily satisfies the average electric load from the heavy equipment, but cannot by itself absorb the surges in demand caused by the mining operation. To absorb this momentary extra load, the plant is interconnected with Alberta Power Ltd. through two 72-kV tielines.
