    Multiple Providers.
    One Simple Rate.

    No pancaked transmission rates - just one rate across multiple transmission providers. It's easy. It's economical. It's yours for the using.

    Go to OASIS/ Deals/WC Wizard. Query on the POR and POD you need, choose the number of providers, identify the MW needed, and let the WC Wizard do the rest.

    Looking to Buy
    Long-Term Firm Transmission?

    You've found the place. TSGT's policies for requesting long-term firm transmission service are outlined below. Should you have questions about the process, contact us at


      • $5,000 non-refundable administration fee must be included with application.
      • A deposit equal to one-month's transmission service fee must be included. Calculate the one-month's fee as follows: # of MW Requested * TSGT OATT rate for yearly service / 12 months = one month's service deposit.
      • Applicant must also fill out an application, pursuant to Section 17.2 of the TSGT OATT.

      Note: Your application is considered incomplete until all items are received by TSGT. Once the application is determined to be complete and valid, a queue date and time will be assigned based on the date of validity - which may or may not be the TSR date of entry on the OASIS.
