| Description: | This Nodal Protocol Revision Request (NPRR) creates a new variation of ERCOT’s existing mothball process to allow Resource Entities to operate their Facilities during summer peak Load periods without having to go through the existing mothballing process each year. This NPRR modifies the Protocols to allow a Resource Entity to designate that its Generation Resource will operate only on a seasonal basis (i.e., at least during the period June 1 to September 30). Additional language changes are provided to describe the process for ERCOT to review the request to operate seasonally and to allow ERCOT to request the Generation Resource to become available earlier than June 1 or remain available after September 30 if ERCOT determines that the Generation Resource is needed for reliability reasons. |
| Reason: | The current ERCOT Protocols do not have a designation that accurately reflects the status of a unit that intends to operate every summer but not be available at other times of the year. Because such seasonal operation may mean that the Resource would not be in operation for more than 180 days, the existing ERCOT process to "mothball" a Generation Resource comes into effect. That process requires substantial efforts on the part of both ERCOT and the Resource Entity to "mothball" then "un-mothball" the Resource when it returns to service. This NPRR creates a more efficient process by allowing the Generation Resource to remain modeled in the ERCOT systems while it is not available for operation and allows the Generation Resource to be shown as on Planned Outage in the Outage Scheduler during the period that it is not available for operation. To facilitate these changes, this NPRR adds a new checkbox on the Notification of Suspension of Operations form notifying ERCOT (and through the existing posting process, ERCOT Market Participants as well) that a Generation Resource owner plans to seasonally operate the Resource for a specific period of time. It also creates a new checkbox on the Notification of Change of Generation Resource Designation form to allow a Generation Resource to change from seasonal operation back to year-round operation if desired. This form is also revised to provide a Market Notice if the Generation Resource needs to modify its summer Operating Period (i.e., to start earlier than June 1 or to end later than September 30). The changes described in this NPRR will provide transparency to the market and simplify the process to allow Generation Resources to operate seasonally without all the complications of the existing mothball process. |
