Advanced Technology Turbines Lower NOx Emissions at Crossfield Energy Centre
ENMAX's new Crossfield Energy Centre, now under construction and scheduled for completion in the fall of 2009, is among the first peaking facilities in North America to make use of ultra-dry low-NOx turbines. These units deliver improved control of the combustion process, which helps lower the amount of NOx generated by the natural gas-fired turbines to approximately 15 parts per million (ppm). This level is approximately 10 ppm lower than the 25 ppm of NOx generated by conventional natural gas turbines. The units also do not require water
for their operation, an important conservation consideration.
In addition, the Crossfield Energy Centre will limit particulate emissions (e.g., soot), and emit about 0.55 tonnes of GHGs per megawatt hour (MWh), which is approximately 45% less GHGs than a traditional coal-fired facilities generate per MWh.
Peaking facility turbines must have the capability to come on quickly to respond to the variations in electrical load demand that occur throughout the day. ENMAX chose this turbine as it is able to excel at this primary function, while limiting emissions that are harmful to the environment.
