When comparing electricity providers in Maryland, two prominent names emerge Potomac Edison and Pepco. Both utility companies are responsible for delivering power and responding to power-related emergencies. However, critical differences between the two companies may influence consumers’ decisions when searching for the best electricity provider.

Potomac Edison services over 220,000 residential customers and more than 34,000 businesses in Maryland, while Pepco provides energy services to over 894,000 customers across Washington, DC, and surrounding areas in Maryland.

Each company offers different rates and renewable energy options for their customers to consider. Understanding these differences is essential for making an informed choice when selecting a regional utility energy provider.

Potomac Edison VS Pepco Comparison

Key Differences

Potomac Edison and Pepco are two major electricity providers in Maryland, offering services to both residential and business customers. An important factor when comparing the two utilities is their respective prices; Potomac Edison currently has a price to compare of 9.22¢, whereas Pepco’s price to reach can be found here. Keep in mind that these rates may change in the future.

Another critical difference between the two utilities is their service area in Maryland. While Potomac Edison serves customers in western Maryland, Pepco provides services in central and southern parts of the state.

Regarding customer reviews, both utility companies have received mixed feedback on their services. Some customers praise their responsiveness to outages, while others find their customer service lacking and billing practices confusing.


Potomac Edison and Pepco, as regulated utility companies, are both governed by the Maryland Public Service Commission, which oversees their prices and services. They are both involved in electricity distribution but do not handle generation, meaning other suppliers produce the actual power.

Maryland residents can choose their electric supplier through the Energy Choice program, which allows them to select from various electricity providers in the market to meet their specific needs.

Both utilities offer customers a standard rate for electricity supply. Still, they also allow customers to switch to an alternative electric supplier to find better prices or customer reviews.

Part of the Maryland Public Service Commission’s role is to ensure fair competition between electricity suppliers, thus offering customers more choices in the energy market.

Aside from Potomac Edison and Pepco, other major utility companies in Maryland, like BGE and Delmarva Power, operate in various parts of the state.

Maryland residents and businesses need to be aware of these differences and similarities as it can help them make more informed decisions when selecting an electricity provider suitable for their needs and location.

Electricity Rate Comparison

Rate Structures

When comparing Potomac Edison and Pepco, it’s essential to consider their different electricity rate structures. Potomac Edison’s current standard offer service rate is 6.858 cents per kilowatt-hour. In contrast, Pepco does not provide its existing rate structure, but you can compare their energy rates using tools available at their respective websites.

Both suppliers offer fixed-rate and variable-rate options for customers choosing different energy plans. A fixed-rate energy plan locks in the generation rate for the entire contract term, offering consistent and predictable costs for the customer. A variable-rate plan comes with a fluctuating generation rate that depends on market prices, which can save money and expose customers to potential rate increases.

Impact on Customers

When analyzing the impact of Potomac Edison and Pepco’s electricity rates on customers, examining both the supply rate and the supply charges associated with their energy plans is necessary. The supply rate, expressed in cents per kilowatt-hour, is the cost of electricity generation. The supply charges are the overall fees customers need to pay for energy usage.

A lower electricity rate does not always guarantee lower bills, as other factors such as consumption patterns, renewable energy plans, efficiency initiatives, and seasonal fluctuations can impact overall costs. A rate comparison tool can help customers select the most suitable energy plan.

In conclusion, consumers should carefully assess Potomac Edison and Pepco’s rate structures, energy plans, and potential impacts on overall costs before deciding to switch electricity providers. By doing so, customers can ensure they select the most appropriate electricity provider and plan for their specific requirements.

Energy Choices and Options

Energy Mix

When comparing electricity providers like Potomac Edison and Pepco in Maryland, it’s essential to consider their energy mix or the combination of energy sources used to generate electricity. Renewable sources like solar and wind power are becoming increasingly important in the state’s energy supply mix as the government promotes clean energy initiatives.

Both Potomac Edison and Pepco now have business energy plans that offer renewable energy options, enabling customers to choose projects with a higher percentage of renewable energy. Some notable electricity providers, such as Constellation, Direct Energy, Tomorrow Energy, and Energy Harbor, have incorporated renewables into their offerings, allowing customers to participate in environmentally conscious programs.

Energy Plans

In a deregulated energy market like Maryland, customers have the power of energy choice and can select their electricity provider and plan. The different types of energy plans, such as fixed-rate, variable-rate, and green energy plans, are available from various electricity suppliers in the state.

Fixed-rate plans lock in a specific rate per kilowatt-hour for the entire contract period, providing customers with stability and predictability in their energy bills. This option is particularly appealing during winter when energy demands are higher, and prices may fluctuate.

Variable-rate electricity plans allow for more flexibility with monthly rates determined by market conditions. These plans can result in cost savings during low energy prices, but they can also subject customers to potentially higher costs when demand or wholesale prices increase. Comparing the best electricity rates provider is crucial when considering a variable-rate plan.

Energy mix and available energy plans are among the essential factors to consider when evaluating the pros and cons of Potomac Edison and Pepco and other electricity providers like Baltimore Gas and Electric, Exelon, and more.

By understanding the different options, customers can decide which electricity supplier and plan type suit their needs and preferences in an increasingly diverse and competitive energy market.

Market Context and Potential Future Developments

In Maryland, the energy market is primarily serviced by four major Investor-owned Owned Utilities (IOUs): PepcoPotomac EdisonBaltimore Gas and Electric (BGE), and Delmarva Power and Light. These utilities serve most Maryland residents and businesses across regions such as Baltimore, Washington D.C., and other surrounding areas.

Pepco, a subsidiary of Exelon, primarily covers the Washington D.C. area and parts of two surrounding counties. Their services reach millions of customers, contributing to Exelon becoming one of the largest U.S. electric utility providers and their other subsidiaries, Commonwealth Edison (ComEd) and PECO Energy.

In contrast, local utility company Potomac Edison, a subsidiary of FirstEnergy, primarily serves western Maryland. Being a smaller utility company than its counterparts, Potomac Edison’s influence in the market could be more extensive. However, they remain dedicated to improving service reliability and addressing customer needs.

One of the contributing factors to the market’s dynamism is the concept of Energy Choice. This initiative encourages Maryland residents and businesses to take advantage of comparing and selecting their preferred Maryland electric suppliers within the state’s deregulated electricity market. The Maryland Public Service Commission oversees these suppliers, ensuring fair competition and promoting customer choice.

As the energy landscape continues evolving, Pepco and Potomac Edison have been improving their environmental efforts. For instance, EmPOWER Maryland has reported GHG reduction achievements from residential programs implemented by utility providers.

However, there is room for improvement, as the proportion of savings to the size of their electricity sales varies widely among local utility providers.

The Maryland electricity market remains complex and dynamic due to the influence of significant utility providers like Pepco and Potomac Edison, the policies set forth by the Maryland Public Service Commission, energy deregulation, and the growing customer interest in environmentally-conscious electricity sourcing.

As energy choice allows customers to select suitable providers, the utilities’ approach to meeting customer demands and addressing environmental concerns will play a critical role in shaping the market’s future developments.
