On March 3, 2017, Southwest Power Pool, Inc. ("SPP")
filed revisions to its Open Access Transmission Tariff
("Tariff") to implement a Resource Adequacy Requirement
("RAR") applicable to all entities responsible for
serving load ("LREs") within the SPP Balancing Authority
Area ("BAA"). SPP seeks to implement the RAR for the
forthcoming summer period from June 1, 2017 through September 30,
2017, while delaying the assessment of penalties for non-compliance
until the 2018 RAR cycle.
According to the filing, SPP staff and stakeholders have been
discussing the need for resource adequacy within the SPP BAA since
2014. SPP maintains that its existing mechanisms to assure adequate
resource and planning reserve capacity have been rendered
insufficient by the integration of new transmission facilities and
load covering an ever-widening geographic footprint.
