How could the Murphy administration's green energy agenda affect PJM Interconnection?
Green energy push may increase operational costs and strain PJM's regional grid. The Murphy administration's pursuit of an aggressive green energy agenda led to the closure of conventional generating capacity in New Jersey, including the Oyster Creek nuclear plant and the B.L. England generating station. This shift, combined with the state's offshore wind ambitions, has contributed to tightening supply and growing demand within the PJM regional power market. These factors, along with transmission constraints, are reported to be contributing to higher electricity costs for New Jerseyans, placing operational and financial pressure on PJM Interconnection.

How it reaches PJM Interconnection
-
New Jersey's average residential electricity rate climbed 63.5% between 2018 and July 2026, rising from 15.41 cents per kilowatt-hour to 25.19 cents per kilowatt-hour. This increase significantly outpaced the national average, which rose approximately 42.3% over the same period. The report notes that New Jersey's rates surged dramatically in 2025 following major electricity supply price increases.
The full event1independent outlet -
New Jersey operates within the larger PJM regional power market. The combination of tightening supply, growing demand, and transmission constraints resulting from these energy shifts has been reported to contribute to higher costs in the region.

Why it matters
For PJM Interconnection, which manages the regional transmission grid, the structural shift toward intermittent green energy sources and the loss of stable conventional capacity creates significant operational challenges. Managing tightening supply and transmission constraints requires complex and costly infrastructure planning and market adjustments, directly impacting the organization's stability and cost structure.
This situation is part of a broader energy affordability crisis in New Jersey, where electricity rates have risen substantially faster than the national average. The state's energy policies, including the push for offshore wind and reliance on solar technologies, are central to this debate, placing the burden of grid stability and cost management onto regional market operators like PJM.
What we don't know yet
- Will PJM Interconnection be able to mitigate the rising costs through new infrastructure investments?
- How will the state's continued reliance on solar technologies affect the stability of the PJM market?
