Summary of key findings

  • Voltage and thermal issues remain in Zone 1 under contingency conditions. The results of the 2026 contingency analysis (NERC Category B or TPL-002 conditions) performed on Zone 1 can be found in Table ZS-4. Please note that because this is a 15-year projected scenario, new projects were not necessarily added to the Assessment based upon these results. However, we will continue to monitor these situations in future scenarios to determine which project(s) may solve these potential issues.

Assessment of Steady State Compliance with NERC Standards

The mitigation plans comprised of planned, proposed, and provisional project as well as appropriate system adjustments identified for Zone 1 in this Assessment will allow the ATC system in Zone 1 to meet the steady state portions of NERC standards TPL-001 and TPL-002 in each of the five years 2012-2016, and for the 2017-2021 planning horizon.
