Gas Capacity Release Offer Class

Description:The release of available pipeline or storage capacity to another party.
Detail:

Gas Capacity Release Offer applies to Gas Pipelines and Gas Storages. It is a mechanism by utility can earn revenue on extra reserved capacity when capacity utilization is low. Capacity release optimization balances revenue obtained from releasing the capacity and ability to serve demand. For storages, withdrawal/injection capability will be affected if you release storage capacity. A given capacity release object can either be assigned to a group of pipelines forming a contiguous path or a single storage. The Capacity Release class has memberships to "Gas Pipelines" and "Gas Storages" with the following properties:

  • Term: Capacity is release decisions are made for a term. A term is a time period (3 months, 1 year) defined by the user.
  • Release Type: Capacity release decision type could either be Base, Swing, or Deal.
  • Revenue Basis: Per day revenue obtained by releasing per unit of capacity.
  • Revenue Adder: Per day revenue obtained in addition to revenue basis for releasing per unit of capacity.
The output of the capacity release optimization can be viewed in the PLEXOS output screen for the modeled capacity release objects. The optimization problem could be framed at the time granularity specified by the user. To obtain capacity released for time granularity higher than the optimization time granularity, a simple average is performed to rollup the optimization results to desired time granularity.
