Factbox: Most Alberta oil sands power generation shut due wildfires

That is down from around 30 percent Friday afternoon.

For a factbox on crude oil production in the area, see:

Cogeneration plants produce electricity and steam. The electricity powers oil sand operations with any surplus energy sold to the local grid, while the steam is used to cook the oil sands to produce crude.

There are about 3,200 MW of power cogeneration capacity serving the oil sands industry in the province of Alberta, with about two-thirds located in the Fort McMurray area.

Of the roughly 2,200 MW of cogeneration capacity in the fire-ravaged area, less than 400 MW operated Monday morning and Sunday afternoon versus about 650 MW on Friday afternoon, according to data from the Alberta Electric System Operator (AESO).

AESO operates the province's power grid.

Before the fire reached Fort McMurray, the cogeneration units in the area were producing about 1,300 MW of power, according to local media reports.

Since the fire started on May 1, generators have shut the McKay River plant on May 4, the Syncrude plant on May 7 and the Kearl and Firebag plants by May 8, according to data from the AESO.
