1. WEQ EC Scoping Task Force on Coordination of Service Across Multiple Transmission Systems In Order 890, FERC directed transmission providers, working through NAESB, to develop business practice standards related to coordination of requests across multiple transmission systems. Problem to be Addressed (Simplified Statement) Currently, a Transmission Customer hoping to move energy across multiple transmission systems could be left with a financial obligation to pay for a reservation on one system without a guarantee that the whole transmission path may be reserved. This due to: Transmission Providers processing transmission requests independently of one another (and often on different approval timelines), Transmission Providers adhering to strict confirmation deadlines, and Transmission Providers having no consistent mechanism to accommodate coordination of requests. 8/17/20101Task Force Presentation to WEQ EC

5. The basic recommended process relies on the customer, after submitting a request on each system, to communicate true-up information to each transmission provider. Proposed 3 Step Process 1. Customer flags the set of requests for service across multiple systems (linked group). 2. Each Transmission Provider processes the request on its system the same as it would process any request on its system (pre-true- up final state). 3. Upon confirmation, the Customer determines the final capacity amount of each request (true-up), which must be equal to or less than the capacity offered. The amount of capacity the Customer confirms may vary per transmission system. Task Force Presentation to WEQ EC8/17/20105
