Maryland Commercial Electricity and Natural Gas Supply

Maryland Commercial Electricity and Natural Gas Market

Introduction

Maryland sits at the nexus of the Mid‑Atlantic economy. Home to major ports, biotechnology firms, government agencies and a vibrant service sector, the state’s commercial landscape demands reliable and affordable energy. Approximately six million people live in Maryland, and its economy generates billions in gross state product every year. Businesses range from small hospitality operators along the Chesapeake Bay to high‑tech research companies in Montgomery County. Because energy expenses represent a significant share of operating costs, Maryland’s shift toward a deregulated electricity and natural‑gas market has profound implications for commercial customers.

Prior to deregulation, Maryland’s investor‑owned utilities controlled both the generation and delivery of power. With no competition, electricity rates remained high and customers lacked choice【611258619887010†L50-L54】. Recognizing that monopolistic markets hinder innovation and raise costs, lawmakers pursued reforms at the close of the 20th century. Today, Maryland businesses can purchase electricity and natural gas from a range of licensed suppliers while still receiving delivery from their local utility. This article explores how deregulation unfolded in Maryland, examines current pricing and energy mixes, profiles key utilities and suppliers, outlines available plan types, and discusses the benefits, challenges and policy landscape shaping the state’s energy future.

History of deregulation

The Electric Customer Choice and Competition Act of 1999 marked the beginning of energy deregulation in Maryland. Prior to the law’s passage, state utilities generated and delivered electricity to all customers, resulting in sky‑high rates【611258619887010†L50-L54】. The Act created a competitive retail electricity market by allowing consumers to purchase electricity from licensed Energy Services Companies (ESCOs) while still relying on the utility to deliver the power【611258619887010†L59-L63】. The legislation separated generation and supply from transmission and distribution, thereby unbundling bills and introducing rate transparency.

Deregulation unfolded in phases. The initial law permitted consumers to select an electricity supplier beginning in 2000, but it also established rate caps to protect customers from potential price spikes. Over time the caps were lifted, and more suppliers entered the market. The Public Service Commission oversees supplier licensing, consumer protections and competitive market rules. Maryland also deregulated natural‑gas supply under similar legislation, enabling customers to purchase gas from competitive suppliers while paying regulated delivery charges to utilities.

Current energy prices and comparison

Energy pricing is dynamic and varies by utility territory, contract type and market conditions. According to the U.S. Energy Information Administration (EIA), Maryland’s average retail electricity price for commercial customers hovered around 12 ¢/kWh in early 2025—slightly below the national average. Residential rates were closer to 15 ¢/kWh. Natural‑gas prices fluctuate seasonally; commercial customers in the Mid‑Atlantic paid roughly $10–$12 per thousand cubic feet (MCF) in 2024, while residential customers paid around $13–$14 per MCF. These figures provide benchmarks for evaluating supplier offers. Because Maryland’s grid is part of the PJM Interconnection, wholesale electricity prices are influenced by regional demand, fuel costs and transmission constraints.

Energy generation mix and environmental policy

Maryland’s energy portfolio reflects both its coastal geography and policy ambitions. The state relies heavily on nuclear power from the Calvert Cliffs facility, which provides roughly 40 percent of net electricity generation【611258619887010†L82-L84】. Natural gas, coal and petroleum contribute the remainder. Maryland has significantly expanded renewable energy in recent years and set a Renewable Portfolio Standard (RPS) requiring 50 percent of electricity sales to come from renewable sources by 2030【611258619887010†L85-L87】. As of 2020, renewables—primarily wind, solar and biomass—accounted for about 11 percent of the state’s generation mix【611258619887010†L85-L87】. Offshore wind projects in the Atlantic are poised to boost renewable capacity further.

Maryland is also the second‑largest exporter of coal in the United States. Coal exports through the port of Baltimore accounted for about one‑quarter of U.S. coal exports in 2020【611258619887010†L88-L91】. At the same time, the state participates in the Regional Greenhouse Gas Initiative (RGGI), a cap‑and‑trade program that aims to reduce carbon dioxide emissions【611258619887010†L92-L93】. Maryland has implemented stringent building energy codes and requires new construction to meet energy‑efficiency standards【611258619887010†L95-L97】. The state also follows California‑style vehicle fuel economy standards, regulating new vehicles to limit greenhouse‑gas emissions【611258619887010†L97-L100】.

Local utilities and competitive suppliers

Distribution utilities deliver electricity and natural gas to homes and businesses and remain regulated monopolies. Maryland’s major electric and gas utilities include:

  • Baltimore Gas and Electric Company (BGE) – A subsidiary of Exelon and the state’s largest natural‑gas distributor, serving more than one million customers【611258619887010†L104-L110】.
  • Pepco – Serves approximately 842 000 customers in Montgomery and Prince George’s counties【611258619887010†L122-L126】.
  • Potomac Edison – Part of FirstEnergy, delivering electricity to western Maryland【611258619887010†L140-L146】.
  • Delmarva Power – Serves up to 500 000 customers on the Eastern Shore of Maryland and across Delaware【611258619887010†L149-L153】.
  • Washington Gas – A natural‑gas utility serving suburban areas around Washington, D.C.【611258619887010†L158-L162】.

Competitive electricity suppliers, known as Energy Services Companies (ESCOs), purchase power on the wholesale market and sell it to retail customers. Maryland businesses can shop among dozens of suppliers offering various pricing structures and value‑added services. Some suppliers specialize in green energy while others focus on budget plans or fixed‑rate contracts. Natural‑gas suppliers offer similar options, allowing customers to lock in fixed prices or opt for variable rates tied to market indices.

Types of plans and pricing structures

Commercial customers in Maryland can choose among several plan types:

  • Fixed‑rate plans. The per‑kilowatt‑hour price remains constant for the duration of the contract, typically 12, 24 or 36 months. Fixed rates provide budget certainty and protect customers against wholesale price spikes.
  • Variable‑rate plans. The price changes monthly based on market conditions. While variable plans can offer savings when wholesale prices fall, they expose customers to volatility. Businesses with flexible budgets may benefit in low‑price periods.
  • Indexed or market‑based plans. Prices are tied to a market index, such as PJM real‑time or day‑ahead pricing plus a supplier margin. Customers may hedge a portion of their load while floating the remainder on the index, balancing risk and reward.
  • Renewable energy plans. ESCOs offer plans with varying percentages of renewable content, including 100 percent renewable energy. These plans help companies meet sustainability goals and may qualify for renewable energy credits.

Natural‑gas plans mirror these structures, offering fixed‑price contracts, variable rates tied to natural‑gas indices and hybrid arrangements. Contract terms may include pass‑through charges for storage and balancing or require minimum usage levels. Businesses should review contract language carefully and consult experts if necessary.

Benefits of deregulation

Deregulation introduced competition to Maryland’s energy markets, giving customers the ability to choose suppliers based on price, service quality, renewable content or other preferences. For commercial customers, competition can lead to lower rates, especially when wholesale prices decline. Businesses can negotiate tailored contracts, aggregate multiple accounts for volume discounts or participate in municipal energy aggregation programs.

Choice has also spurred innovation. Suppliers offer energy management tools, bill analysis, demand response programs and renewable‑energy certificates. In addition, deregulation encourages transparency in billing by separating supply and delivery costs, helping customers understand where their money goes. Because utilities continue to deliver the energy, reliability remains the same regardless of the supplier chosen.

Challenges and consumer protections

With more choice comes complexity. Navigating dozens of supplier offers and understanding contract terms can be daunting. Some contracts include early‑termination fees, automatic renewals or hidden charges. To protect consumers, the Maryland Public Service Commission regulates suppliers and requires clear disclosure of rates, fees and contract length. Customers have the right to rescind a contract within a specified period after enrollment. The Commission maintains a list of licensed suppliers and investigates complaints.

Another challenge is market volatility. Wholesale electricity prices can spike during extreme weather or fuel‑supply disruptions, affecting customers on variable or indexed plans. While fixed‑rate contracts offer protection, they may be higher than current market rates when signed. Businesses should weigh the trade‑off between price certainty and potential savings from market exposure.

Energy efficiency and demand response

Maryland is a leader in energy efficiency. The state’s EmPOWER Maryland program, launched in 2008, requires utilities to achieve annual energy‑savings targets. Utilities offer incentives and rebates for upgrading lighting, HVAC systems, refrigeration, process equipment and building shells. Programs are available for small businesses, large commercial and industrial customers, and multifamily buildings. Maryland’s building energy codes, modeled after the International Energy Conservation Code, ensure that new construction meets high efficiency standards.

Demand response programs allow customers to receive payments for reducing load during peak demand events or grid emergencies. PJM, the regional transmission organization, administers demand response markets, and local utilities provide their own programs. Businesses can enroll through curtailment service providers who aggregate demand reductions and bid them into the market. Participation helps lower capacity costs and enhances grid reliability.

Natural‑gas market

Maryland’s natural‑gas supply is also deregulated. Customers can choose a competitive supplier for the commodity, while local utilities—BGE, Washington Gas, Delmarva Power and Columbia Gas—deliver the gas and maintain pipelines. Gas suppliers offer fixed‑price contracts that lock in a per‑therm or per‑MCF rate for a specified term or variable rates tied to market indices. Because gas prices are highly seasonal, many customers prefer fixed‑rate plans during winter to avoid price spikes.

Businesses should examine supply offers for details about pass‑through charges, storage costs and balancing services. Some suppliers bundle energy efficiency services or renewable natural‑gas options. Local distribution companies provide budget billing and energy‑assistance programs for small businesses facing financial hardship.

Policy landscape and future outlook

Maryland’s policy landscape continues to evolve. The state is committed to reducing greenhouse‑gas emissions and increasing renewable energy through its RPS and participation in RGGI. Offshore wind development, community solar projects and battery storage are expanding rapidly. Legislative efforts such as the Maryland Clean Energy Jobs Act and the Climate Solutions Now Act set ambitious targets for clean energy deployment and greenhouse‑gas reduction.

For commercial customers, these policies translate into more opportunities to procure renewable energy, participate in demand response and receive incentives for energy efficiency. Over the coming years, distributed energy resources and smart‑grid technologies are expected to play larger roles. Businesses that stay informed and engage with the evolving market can leverage deregulation and policy incentives to manage costs and advance sustainability goals.

Conclusion

Maryland’s transition from a monopolistic utility model to a competitive energy marketplace has expanded choices for businesses and residents. The Electric Customer Choice and Competition Act of 1999 ended the utility monopoly on supply and paved the way for dozens of licensed suppliers. Today, commercial customers can secure fixed or variable electricity and natural‑gas contracts, select renewable options, participate in aggregation programs and access robust energy‑efficiency incentives. While navigating supplier offers requires diligence, the benefits of competition—price transparency, product innovation and customer service—are significant. As Maryland pursues ambitious climate goals and infrastructure modernization, its deregulated energy markets will continue to evolve. By staying informed and proactive, Maryland businesses can capture savings, reduce carbon footprints and contribute to a more sustainable energy future.
