Pennsylvania's electricity rates are high due to various factors, including fixed charges, heating costs, and infrastructure fees. Customers pay more during peak hours, and default utility rates can exceed competitive supplier prices. The state's electricity grid is managed by PJM, which serves 12 other states and DC, influencing supply and demand dynamics and capacity costs. PJM's capacity auction in July 2024 resulted in an 833% price increase for 2025-2026, impacting residential bills. Pennsylvania's deregulated market allows residents to shop for competitive rates, and renewable energy plans offer sustainable options. Commercial rates are generally lower than residential rates, and solar systems provide long-term savings. Understanding these factors is crucial for managing electricity expenses in Pennsylvania.

What You'll Learn
High electricity consumption
PJM requires utilities to ensure they can meet future electricity demands, including during peak periods, through a "capacity auction" market. In this market, electricity suppliers bid to provide the physical infrastructure that will generate electricity in the future. Capacity fees are part of the PJM market structure, incentivizing the development of new power plants and generation assets. Generation companies receive capacity fees to guarantee sufficient power during high-demand periods.
However, capacity costs in Pennsylvania have skyrocketed. In the July 2024 PJM capacity auction, the bid price was 833% higher than the previous year, translating to a 10-20% increase in residential electricity bills starting in June 2025. This significant increase in capacity costs is due to the growing demand for electricity and the lack of energy supply to meet that demand.
The increase in electricity demand within PJM is coinciding with a shrinking supply. Many old power plants in the PJM grid are being retired as they reach the end of their useful lives, emit high levels of pollution, or become less profitable with the rise of affordable natural gas and solar energy. Additionally, PJM has been slow to approve and connect hundreds of proposed new power plants, most of which are solar- and battery-based, to transmission lines. This "interconnection queue" prevents new generation capacity from coming online, even though companies are eager to build more.
To address high electricity consumption and its impact on prices, Pennsylvania residents can explore ways to conserve energy and reduce their usage during peak hours. Additionally, the state can expedite the approval and construction of new power plants, especially those utilizing renewable energy sources.

PJM capacity auction
Pennsylvania's electricity grid is managed by PJM, which also coordinates the flow of electricity through 12 other states and the District of Columbia. PJM holds capacity auctions, in which electricity suppliers bid to provide physical infrastructure that will generate electricity in the future. The goal of these auctions is to incentivize the development of new power plants and generation assets.
The July 2024 PJM capacity auction for the 2025-2026 delivery year resulted in a bid price that was 833% higher than the previous year. This dramatic increase was due to tightening supply and demand conditions. Demand for electricity in the PJ region is growing, driven by population growth, commercial and industrial development, and more extreme weather patterns. At the same time, the supply of electricity is constrained due to the retirement of old power plants and the slow process of building new ones.
The high capacity prices in the 2024 auction sent shockwaves through the region, with prices soaring to $269.92/MW-day for most of its footprint, up from $28.92/MW-day. The total cost of the auction jumped to $14.7 billion, a significant increase from the previous year's total of $2.2 billion.
The 2024 auction also reflected PJM's commitment to expanding capacity requirements for all resource types, including solar, wind, batteries, and hybrid resources. PJM is also working to enhance its process for connecting new generation resources to the system, including clearing all projects in its transition queue over the next 18 months.
While the capacity costs from the PJM auction make up a relatively small part of electric bills, the impact on consumers in Pennsylvania is significant. The increase in capacity costs is expected to result in a 10-20% increase in residential electricity bills in Pennsylvania, with businesses facing increases of up to 29%.

Aging power plants
Pennsylvania's electricity rates are high due to several factors, including aging power plants. PJM, the company that manages the state's electric grid, has seen many old power plants retire as they reach the end of their useful lives. This reduction in supply, coupled with increasing demand, has resulted in higher prices. The retirement of these plants also creates a challenge for PJM, as they need to ensure enough power generation capacity to meet future electricity demands.
The process of building new power plants is often slow, with PJM facing challenges such as local opposition, supply chain issues, and financing. This has resulted in a long "interconnection queue," preventing new power generation sources from coming online quickly. Additionally, some older power plants emit high levels of pollution, requiring costly retrofits to meet current pollution limits.
The impact of these aging power plants on electricity prices is significant. For example, in 2025, a PECO residential customer using 700 kilowatt-hours of electricity monthly experienced a 10% increase in their bill, amounting to an additional $13.58. Similar increases are expected to continue, with residential customers potentially facing up to a 20% increase in electricity bills.
To address the issue of aging power plants and high electricity prices, Pennsylvania needs to expedite the transition to new power generation sources. This includes facilitating the construction of new power plants, especially those utilizing renewable energy sources such as solar and battery storage. By increasing the speed at which new power plants come online, Pennsylvania can help alleviate the strain on the state's power grid and work towards providing more affordable electricity to its residents.
Overall, the aging power plants in Pennsylvania have contributed to the state's high electricity prices. By addressing the challenges associated with building new power generation sources and transitioning to renewable energy options, Pennsylvania can work towards mitigating the impact of aging infrastructure on electricity rates.

Demand and supply
Pennsylvania's electricity rates are influenced by a combination of demand and supply factors. On the demand side, several factors contribute to the high electricity consumption in the state:
- Population Growth and Commercial Development: As the population grows and commercial and industrial activities expand, the demand for electricity increases. This is particularly evident in Pennsylvania, where there is a high demand for electricity from data centers and other sources.
- Weather Conditions: Extreme weather patterns, such as heat waves and winter storms, drive up electricity usage for heating or cooling, leading to higher demand.
- Usage Patterns: Electricity usage tends to peak during certain times of the day or year, such as hot summer afternoons or cold winter months. Customers are often charged based on their usage during these peak hours, contributing to higher overall demand.
On the supply side, several factors affect the availability and cost of electricity in Pennsylvania:
- Power Plant Retirements: Many older power plants in the PJM grid, which manages Pennsylvania's electricity, are being retired due to age, profitability, and pollution concerns. This reduces the overall supply available.
- Slow Development of New Power Plants: The process of building new power plants, particularly solar and battery-based ones, is slow due to interconnection queue issues, local opposition, and supply chain and financing challenges. This delays the addition of new generation capacity to the grid.
- Capacity Costs: PJM's capacity auctions, which incentivize power generators to maintain sufficient supply during peak demand, have resulted in extremely high pricing. These capacity costs are passed on to consumers, contributing to higher electricity bills.
- Aging Infrastructure: Utilities have been slow to upgrade their aging wires and infrastructure, leading to higher costs that are reflected in consumer bills.
