Puget Sound Energy Wholesale Customer Transmission Aids

Fire Weather Forecasted

Hot, dry and windy conditions are forecast for the Kittitas Valley. As part of PSE’s wildfire safe operations, we turned on system settings that are more sensitive to potential hazards.

Enhanced Powerline Settings are designed to help keep you safe, but they can result in unplanned power outages.

This is not a Public Safety Power Shutoff, where we proactively turn off power in advance of severe weather. 

For more information or to report a power outage, visit PSE’s Outage map.

Wholesale customer transmission instructions

Puget Sound Energy offers firm and non-firm wholesale transmission services in Washington, Oregon and western Montana. The following instructions are required steps in order to obtain transmission services.

Please note that all customers desiring transmission services from PSE are required to use the Open Access Same-Time Information System (OASIS) to submit their requests.

Step one: Make sure you have a D-U-N-S number

Go to the Dun & Bradstreet D-U-N-S Request Service website to request a Data Universal Numbering System (D-U-N-S) number if you do not already have one. For additional information see the About the D-U-N-S Number page on the D&B site.

Note: If you have both a transmission division and a power marketing division in your company, each division will need to have its own unique D-U-N-S number.

Step two: Register as a transmission customer

Complete the form on the OATI (OASIS) webRegistry site.

Step three: Register with OATI (OASIS) webCARES™

Follow the steps for new registrants on westtrans.net.

Step four: Contact PSE

IMPORTANT! Once you have completed the above steps, please contact the transmaster@pse.com and request to become a transmission customer. We will then perform the necessary steps to authorize you to make transmission requests via OASIS.

Step five: Request your service agreement(s)

If you intend to purchase short-term, point-to-point transmission services at any time, you should request a blanket transmission service agreement by following the instructions.

Additional instructions on how to properly use PSE's OASIS, as well as assistance regarding the requesting of transmission and ancillary services pursuant to PSE's Open Access Transmission Tariff, are available by contacting by contacting Supervisor OASIS & Settlements (425) 577-2616.
