Rising electricity prices blamed on "carbon control"? Pennsylvania abandons regional carbon trading market.

Due to soaring electricity prices and surging data center demand, Pennsylvania has officially decided to withdraw from the regional carbon trading market.

On November 13, Pennsylvania Governor Josh Shapiro signed a bill authorizing the state’s withdrawal from the Regional Greenhouse Gas Initiative (RGGI). This move not only cuts funding associated with this climate initiative, but also marks a significant shift in the state’s energy policy, formally overturning former Governor Tom Wolf’s 2019 decision to join RGGI.

The direct reason behind Pennsylvania’s withdrawal is the worsening regional electricity price crisis. Through its carbon pricing structure, RGGI effectively penalizes the state’s energy sector, especially natural gas and coal-fired power plants. Power plants must purchase allowances for carbon dioxide emissions, which directly drives up wholesale electricity prices, ultimately raising energy bills for businesses and households.

Meanwhile, the rapid expansion of energy-intensive industries such as AI data centers has led to a surge in power demand, further exacerbating supply-demand imbalances and price pressures.

For a long time, Republican senators in Pennsylvania have opposed RGGI. They argue that the mechanism imposes excessive burdens on traditional power plants that serve as pillars of the grid and the industrial economy. According to reports from independent grid operator PJM and state regulators, participation in RGGI could force coal and natural gas power plants to close prematurely, thereby weakening grid resilience and increasing the risk of electricity capacity shortages. Against the backdrop of rising power demand, these concerns have become key factors driving policy change.

Governor Josh Shapiro stated while signing the budget bill that Republicans have for years used RGGI as an excuse to delay substantive discussions on energy production, and “today that excuse is gone.”

He emphasized the hope to actively promote policies in the future that will create more energy sector jobs, integrate more clean energy into the grid, and lower energy costs for all Pennsylvania residents. This decision has also drawn market attention as to whether other neighboring states facing similar electricity price pressures will follow Pennsylvania’s example.
