oasis primarily deals with the purchase and availability of transmission from individual transmission providers with a forward-looking time frame, while e-tag is focused on real-time scheduling and power flow management across multiple systems. nonetheless, the ferc-derived oasis applications and nerc-derived e-tag applications are somewhat duplicative. ferc's plan for the eventual introduction of oasis phase 2 envisions a combined platform to post transmission offerings, allow transmission purchases, and facilitate scheduling and flow management, effectively merging the essential functions of e-tag and oasis. however, there has been very little activity to move towards oasis phase 2 since the introduction of e-tag 1.7 in 2002, and the future remains unclear. as both systems have increased in complexity over time, the difficulties in merging the two independently evolved systems have likewise also increased.
