Wahkiakum County PUD – Cathlamet Substation

The existing Cathlamet substation was 40 years old and near the end of its expected life span when Wahkiakum County PUD hired JH Kelly to rebuild their substation.

The winter power peaks that it handles were near the maximum capacity that the transformer could handle, and JH Kelly constructed a new greenfield substation.

Scope included:

  • 6 weeks
  • $1,200,000 lump sum contract
  • Engineer was Brown and Kayser
  • 115 kv substation
  • Civil and concrete
  • Structural steel erection
  • Conduit, trenching and grounding
  • All mechanical services
  • High voltage was subcontracted to DJ’s Electric
