NAT3 GP plans 20-MW, gas-fired project in Alberta

The Alberta Utilities Commission said in an Aug. 4 notice that NAT-3 Limited Partnership, on behalf of NAT3 GP Inc., filed an Aug. 2 application with the commission for approval to construct and operate a 20-MW plant in the Jenner area.

NAT3 GP will own and operate the proposed Jenner Power Plant. This power generating station will use natural gas to fire internal-combustion generator sets (gensets). Natural gas from a high pressure pipeline is depressured and distributed to 10 gensets, each generating 2 MW. The gas from the pipeline would be heated to combustion temperature in a glycol line heater.

The number of gensets and the individual load are controlled based on the desired power to be generated and sent to the local power grid. Normal capacity is 10 MW and maximum capacity is 20 MW.

Aerial coolers will manage heat rejection from the gensets. The gensets are “lean-burn” and NOx is managed through the use of selective catalytic reduction (SCR) units. The SCR units will use a urea solution (32.5% solution dissolved within deionized water) as a reductant, converting residual NOx into N2 to meet the Alberta Ambient Air Quality Objectives. The urea solution is to be stored on-site within the facility and injected into the exhaust streams.

A spec sheet attached to the application shows emissions date for the Cummins C2000N6C and Cummins C334N6C engine models.
