Upgrade to increase capacity to 71.5 MW

The FNG Project will see an upgrade to the simple cycle gas power plant at Fort Nelson to a combined cycle facility.

This will increase the plant capacity from 47 megawatts to 71.5 megawatts. The new combined cycle plant is considered to be the most efficient and environmentally friendly method of generating electricity using natural gas.

Capacity to increase as emissions, waste water decrease

Upgrading the Fort Nelson Generating Station to a combined cycle facility includes the use of an air-cooled condensor technology designed to significantly reduce the production of waste water, or effluent and raw water usage.

As the facility's capacity goes from 47 megawatts to 71.5 megawatts, greenhouse gas emissions per megawatt will be reduced by 15 to 20 per cent.

The project also includes replacing the existing gas turbine with a General Electric dry low emissions gas turbine. This upgrade eliminates the need to use steam to control emissions, therefore maximizing steam flow to the new steam turbine generator.

The project scope includes:

  • Replacing the existing Once-Through Steam Generator (OTSG) with a higher capacity unit;
  • Adding a new 30 megawatt steam turbine generator;
  • Adding new ducting and duct-firing systems;
  • Adding a new steam turbine building;
  • Adding an air-cooled condenser;
  • Adding a new transmission step-up transformer and station service transformer;
  • Modifications to the existing plant controls, electrical distribution system, piping and structures.
