The Pricing Experiment is LIVE!!!
WestConnect members are making it easier for you to move your energy!
Go to OASIS, click on the WC Wizard, enter the POR and POD and find the
Hourly Non-firm transmission service available at the Regional Rate.
Select the service you wish to buy and off you go.
Before you buy and use the Regional Transmission product, make sure you’ve
done your homework . . .
•Have you executed the new, Non-Firm Annex A service agreement with all the
WestConnect Pricing Experiment Regional TPs (AZPS, EPE, NEVP, PNM,
PSCO, SWTC, TSGT, WACM, & WALC)? Check with your regular contracts
person at each TP to obtain the new service agreement.
•Have you established creditworthiness with each Regional TP?
•Have you obtained the service through the OASIS/WC Wizard button?
•Have you followed the proper E-Tagging procedures for all entities involved in
the path?
A few things to remember along the way . . .
•Only Hourly, Non-Firm service is available with the Regional Rate
•Sorry, but no renewals, resales, or redirects are allowed.
•All Regional TPs in the path have to approve the reservation before going to a
CONFIRMED state . . . so be patient. . .
•You can only request the regional service through the WC Wizard interface on
OASIS.
•Confirmed TSR will have a $.09/MWh administrative fee added on your bill, in
addition to the cost of the transmission.
* Losses and scheduling fees for each regional TP will still be charged.
