PJM congestion costs surge to $6B as transmission overloads worsen
PJM congestion costs rose 43% to $6B in the first half of this year, with the market monitor citing transmission bottlenecks on high-voltage lines as the main driver.
VST NRG CEG Congestion costs on PJM, the largest U.S. power Grid, surged 43% to $6B during the first half of this year as overloads on high-voltage Transmission lines escalated, the Grid's Independent watchdog said this week. --Transmission bottlenecks on the Grid during stressful events like storms were the single biggest driver of the increase in soaring wholesale electricity costs, according to Monitoring Analytics, PJM's Independent market monitor. --Price adjustments for Transmission constraints were $6B, up from $2.1B in the year-earlier period, according to the market monitor's report.
That year-over-year increase of $3.9B eclipsed the $2B increase in Natural gas fuel costs, the report said
