  1. Transmission Studies for New Long Term Network Resources Doug Powell Manager Technical System Planning Entergy Services, Inc. September 11, 2006

  2. Two options for designating new Long-Term Network Resources 1. Incremental: Customer requests designation of new generation in addition to existing Network Resources. 2. Delisting/displacement: Customer requests designation of new generation replacing existing Network Resources.

  3. Incremental Study • New resource will be studied in addition to customer’s existing Network Resources. • All network service studies will be performed on an incremental basis, unless service request specifies otherwise.

  4. Delisting/Displacement Study • Delisting study evaluates a new generation resource as a long-term replacement for an existing Network Resource. • Displacement study evaluates a new generation resource as a short-term substitution for an existing Network Resource.

  5. Delisting/Displacement Studies • Performed at Customer’s election. • Customer provides list of Network Resources to de-list/displace or Entergy Transmission can provide the delisting/displacement options for Customer.

  6. Batching of Requests • Customer can elect to have all or a portion of its requests to designate new Network Resources “batched.” • Transmission will perform all studies in the specified “batch” and release the completed System Impact Studies (“SIS”) at one time. • Only requests that are in consecutive order in the SIS queue can be “batched.”

  7. Under the ICT • The ICT will administer the Operating Companies’ OASIS • The ICT will sign the SIS Agreement with customer and perform the System Impact Study • To the extent a Facility Study is necessary and requested, Entergy transmission will conduct the study, subject to the validation of the ICT.
