Power for Communities and Growth
WINLOCK, WASHINGTON — A new power substation near Winlock has been energized, marking an important infrastructure milestone for South Lewis County, nearby communities, and the growing Winlock Industrial Park corridor.
Published reporting describes a 25-megawatt transformer connecting 69 kV transmission service to the local 12 kV distribution network. The facility began service with eight circuits designed to support present electrical needs while creating additional capacity for future growth.
Serving the Regional Load
Of the eight initial circuits, public reporting says four are intended to serve nearby towns, residences, businesses, and other local ratepayers. The remaining four are positioned to support the nearby industrial corridor along Interstate 5 and north of State Route 505.
Industrial development requires more than available land. It requires dependable power, transportation access, utilities, communications, workforce access, and long-term planning.
A Scalable Energy Foundation
Published Winlock Industrial Park planning materials identify Phase 1 at 25 MW, with a second phase scalable toward 50 MW. Future expansion may add capacity as residential, commercial, industrial, and technology-related demand grows.
- Phase 1: 25 MW of published power capacity.
- Phase 2: Scalable toward 50 MW.
- Transmission connection: Reported 69 kV service stepped down to the local 12 kV network.
- Initial service: Eight energized circuits.
- Regional role: Supports community load and the nearby industrial corridor.
Why It Matters for Winlock
Reliable electricity is one of the essential building blocks for homes, small businesses, manufacturing, distribution operations, data-driven services, and future industrial investment.
Combined with planned roadway improvements at the I-5 and SR-505 interchange, the energized substation helps strengthen the infrastructure foundation for expanded commerce, logistics, and industrial opportunity in the Winlock area.
Looking Ahead
The Winlock Industrial Park corridor is positioned for continued planning and infrastructure investment. Power capacity, freeway access, utilities, broadband, and regional connectivity all play a role in how a location can compete for future business opportunity.
Winlock City will continue sharing updates about infrastructure, transportation access, business opportunity, digital assets, and the broader vision for growth in the Winlock area.
