Alberta Electric System Operator (AESO) retained Burns & McDonnell to perform the 2010 long-range planning study in accordance with the NERC TPL reliability standards. The purpose of the study was to perform steady-state load flow, voltage stability and dynamic stability analyses to determine limiting facilities and to identify potential improvements in the AESO transmission system needed to support long-term area growth in years 2015 and 2020.

In 2010, Burns & McDonnell helped AESO perform a long-range planning study to identify facility upgrades and new facilities needed to support projected long-term load growth in the Alberta Interconnect Electric System. As part of the analysis, Burns & McDonnell performed steady state, voltage stability and dynamic stability assessments during Category A, Category B, Category C and Category D contingency outages to identify potential limiting facilities for an increased level of load for three time frames — current and next five and 10 years. The analysis was performed in accordance with the Alberta Reliability Standards TPL-001 through TPL-004 and the AESO Transmission Reliability Criteria. Once problem facilities were identified, Burns & McDonnell developed solutions to mitigate the impacted facilities to support the yearly load growth. The recommended improvements and/or additions were developed using a cost/benefit analysis.
AESO developed the flow models used in this study — 2012, 2015 and 2020 summer peak, summer light and winter peak models.
