- Document Description
- The proposed project is located in city of Mount Shasta and in unincorporated Siskiyou County. The proposed project consists of the demolition of the existing Mount Shasta Substation, construction of the new Lassen Substation, and pole replacement and reconductoring activities. The existing and proposed substations are located to the west in I-5 and the pole replacement, and reconductoring activities would occur both on the west and east of I-5 in the south central portion of unincorporated Siskiyou County. Existing transformers in the Mount Shasta substation would be replaced with 12.47 kV transformers in the new Lassen Substation, which in turn would require the existing 4.16 kV distribution lines that currently supply the city to be upgraded to 12.47 kV distribution lines. To accommodate the additional weight of the new distribution lines and maintain compliance with title 8 of the California code of regulations and CPUC General order 95, 36 wooden poles along the existing 69 kV transmission line running to the northwest and southeast of the proposed substation would be replaced and the existing 69 kV transmission line would be transferred to the new poles. Implementation of the proposed improvements would help ensure PacifiCorp that all equipment and structures comply with current company, state, and federal standards, including the replacement of aging and non-standard equipment and the removal of sulfur hexafluoride distribution breakers, ensure a reliable ongoing electricity supply to the area currently served by the Mount Shasta substation; and facilitate regional bulk transmission voltage stability and improve bulk power transfer across the region.
