FactSet Blog U.S. Grids Target Higher-Voltage Transmission to Alleviate Congestion

In May, ERCOT is expected to decide between its 345 kV and 765 kV long-term transmission plans. If ERCOT chooses the 765 kV plan, it would join several other ISOs in moving towards higher-voltage transmission line buildout to meet rising load and combat congestion along existing transmission pathways. However, various obstacles to this planned buildout remain. In this Energy Market Insight, BTU Analytics looks into current congestion levels across PJM, ERCOT, and MISO and the planned lines under review by those ISOs.
