The Open Access Same-Time Information System (OASIS) provides information about available transmission capability for point-to-point service and a process for requesting transmission service on a non-discriminatory basis. OASIS enables transmission providers and transmission customers to communicate requests and responses to buy and sell available transmission capacity offered under the Open Access Transmission Tariff.
