  7. NAESB Update Wholesale Electric Quadrant ServiceAcross Multiple Transmission Systems (SAMTS) (OASIS Subcommittee) • Some key aspects • Permits combination of requests and reservations over a time period to be coordinated • Only monthly and longer requests may be included (no restriction on reservations) • Requests must be submitted pre-confirmed • If one request is not accepted in full, customer may reduce or withdraw any and all requests in the group • If all requests are accepted at requested capacity, all requests must be confirmed • Time zone mismatch is permitted

  8. NAESB Update Wholesale Electric Quadrant Service Across Multiple Transmission Systems (SAMTS) – cont. (OASIS Subcommittee) • Recommendation sent to EC for approval • Formal comment period ends June 10, 2011 -- link • Technical conference on 5/20/2011 • WEQ Executive Committee to review & vote on 6/30/2011

  9. NAESB Update Wholesale Electric Quadrant • Network Service on OASIS (NITS) (OASIS Subcommittee) • Significant changes • New templates – Network reservations will need to move to the new system • New Network Customers will need to fill out an on-line application on OASIS • Existing Network Customers will not have to make a new application on OASIS • Target for EC completion in 3rd quarter 2011 • NITS work delayed while completing Service Across Multiple Transmission Systems (SAMTS) • OASIS subcommittee plans to send out draft version for informal comments early June • Next steps are dependent upon magnitude of comments received
