Alberta signs off on slight uprates for two Syncrude cogen units

The Alberta Utilities Commission on June 3 approved an application from Syncrude Canada Ltd. for changes at cogeneration units G3 and G5, which are part of an existing industrial system located in the Mildred Lake and Aurora areas.

As a requirement under its Alberta Environmental Protection and Enhancement Act approval, Syncrude is upgrading the G3 and G5 units with Dry Low NOX burner technology in order to meet the Best Available Technology Economically Achievable NOx standard. Syncrude stated that the power unit ratings would be increased from 25 MW to 26 MW due to the conversion to Dry Low NOX technology.

In its application, Syncrude indicated it has received approval from the Alberta Energy Regulator to proceed with the upgrades to the G3 and G5 units. Syncrude stated that the upgrades would take place within the existing footprint, would not increase environmental noise and would reduce emissions to the environment. Syncrude also indicated that it is informing the Alberta Electric System Operator (AESO) of this upgrade and would inform the commission if the AESO expresses any concerns with the upgrades.

The gas-fired Mildred Lake plant site consists of the following units: three units each with a capability of 25 MW, three units each with a capability of 50 MW, one unit with a capability of 67 MW, one unit with a capability of 75 MW and one unit with a capability of 92 MW. Syncrude stated that prior to Jan. 31, 2001, TransAlta Energy Corp. owned and operated the Syncrude Mildred power plant.
