3rd Quarter 2013 VRL Report: Voltage Regulation and Outage Analysis in Multiple States

This report details the monitored elements, contingent elements, and reasons for violations impacting the voltage regulation landscape in various states during the third quarter of 2013. Specifically, it addresses outages and high loading scenarios across regions including Wyoming, Iowa, Missouri, Arkansas, Texas, and New Mexico. Key findings highlight the effects of forced outages and external impacts on voltage levels and operational stability within the electrical grid. The insights aim to inform stakeholders on necessary adjustments and future precautions.
