High PJM grid prices are credit negative for regulated electric utilities, Moody's says

• Regulated utilities in PJM see little benefit from rising capacity prices since they own transmission lines but are generally barred from owning power plants that receive the payments
• PJM capacity prices cleared at $325 per megawatt-day last week, creating affordability concerns that increase regulatory and political risk for utilities passing costs to retail customers
• Independent power producers that own plants and receive capacity payments directly may see credit upgrades, contrasting with the credit-negative outlook for regulated utilities

Summary

Moody's Investors Service warned on Wednesday that surging capacity prices in the PJM Interconnection grid pose credit risks for regulated electric utilities. The alert follows PJM's recent capacity auction, which cleared at $325 per megawatt-day last week.

Key Impact:

Regulated utilities operating in PJM—the largest U.S. electrical grid—face potential credit rating downgrades due to rising costs they must pass through to retail customers. These utilities own transmission infrastructure but are generally prohibited from owning power generation assets in PJM markets, meaning they gain no benefit from higher capacity prices while bearing affordability pressures.

Market Dynamics:

Moody's identified capacity prices as "credit negative" for regulated utilities and load-serving entities focused on maintaining affordable power for residential and commercial customers. The situation increases both regulatory and political risk as these companies balance reliability requirements against cost concerns.

Conversely, independent power producers that own generation assets and receive capacity payments directly may experience credit upgrades from the elevated PJM pricing.

Underlying Drivers:

The rating agency attributed market pressures to three factors reshaping PJM:

• Data center-related load growth
• Power plant retirements
• Transmission infrastructure constraints

Broader Implications:

Moody's emphasized the "increasingly difficult balance between preserving affordability and maintaining reliability" in the PJM market. The situation highlights growing tensions in regulated electricity markets as infrastructure demands intensify while utilities face political pressure to control consumer costs.

The divergent credit implications create a bifurcated market outlook, benefiting generators while pressuring transmission-focused utilities serving retail customers across PJM's 13-state footprint.
