OASIS - Transmission Customers and External Transactions Requirements
- See the OASIS website for registration information. Participation in the Open Access Same-Time Information System (OASIS) is required for all transmission and external-transaction customers in New England. OASIS is an electronic posting system that helps ensure that all transmission customers have timely access to transmission information that will enable them to obtain comparable, open access transmission service on a non-discriminatory basis. Examples of OASIS information include available transfer capability, transmission rates, and system conditions that may give rise to interruptions or curtailments.
- Submit the External Transmission Customer Contact form, if you are an external-transmission customer. This form is required for all external-transmission customers to access the Enhanced Energy Scheduler (EES) software, the ISO’s external transaction reservation system.
- See Transmission Services for details on other requirements and applications for transmission services in New England.
