An underground substation? Just toured Anaheim Public Utilities 69/12kV GIS Park Substation as part of the IEEE PES T&D Expo technical tours.

Anaheim’s 12kV distribution system is 70% underground and one of their five GIS stations is underground. The $20MM EPC SF6 underground substation project was lead by Siemens, Turner Construction and Beta Engineering and was dedicated in October, 2006. Park Substation has excellent reliability and very low O&M costs. The largest O&M cost is for the large air handling system….and mowing the grass (jk).

Next up is the opening reception, keynote address and our two hour panel on investing in major underground programs with Minnesota Power, Georgia Power, PG&E and Eversource Energy. Stay tuned.
