Columbia Renews Challenge to Order That Would Require Consideration of Quantities Deemed to Be Scheduled under Rate Schedule SIT in Determining Scheduling Penalties

摘要

Columbia Gas Transmission Corp. (RP08-295) on 6/22/09 asked the Commission to reverse its recent order conditionally accepting changes to its Storage in Transit (SIT) Rate Schedule. SIT was designed as an interruptible balancing service for shippers with wide swings in daily demand, e.g., electric power plants. Shippers use SIT service in conjunction with transportation service agreements that are deemed subject to Rate Schedule SIT. When daily receipts under a transportation service agreement exceed daily deliveries, Columbia injects the difference into storage on an interruptible basis. When daily deliveries exceed daily receipts, Columbia withdraws the difference out of storage.
