Notre Dame Combustion Turbines and Heat Recovery Steam Generators

Approach

The 32,000 square-foot expansion to the facilities building houses the plant and electrical gear. Two new natural gas compressors were installed to provide high-pressure natural gas to the new combustion turbines. These are housed in a separate new gas compressor building. In addition to the turbines, KFI provided the design for the relocation of the existing water treatment systems within the facilities building and new 20,000 gpm cooling towers to replace the two existing chillers. The project also included connecting to three existing tunnels, rerouting of existing tunnel piping through the new plant, and phased demolition of two tunnels that would be running through the new building’s basement if left in service.

After reviewing the projections laid out in the Utilities Long Range Plan, the team moved forward with a new gas-turbine/HRSG plant featuring two 5.5MW gas turbines, HRSGs with supplemental firing, a new dedicated high pressure gas source, redundant gas compressors and a new substation.
