Grid Congestion Trumps Gas as Biggest Price Driver in PJM
The PJM electric grid's half-year report card, titled 'Market Monitor Finds PJM Wholesale Electricity Markets Competitive,' had an unexpected twist buried within its three-paragraph text. While the introduction and first few paragraphs seemed to indicate a positive assessment of the grid's performance, further reading revealed that the capacity market had actually failed for three consecutive years.
The report blames data centers for the capacity market's struggles, but another important detail caught the attention of those following the energy sector: the biggest single driver of PJM's price spike was not natural gas, as some might have expected. Instead, it was grid congestion that caused the largest portion of the price increase.
The report did not provide further details on how to address the issue or what steps are being taken to alleviate grid congestion. However, this revelation may prompt a reevaluation of previous arguments and discussions surrounding energy prices in Harrisburg.
