Commonwealth Edison offers a range of electric service options to suit different needs and budgets. Their most basic plan is the Smart Rate plan, which charges customers based on the time of day they use electricity.
The Smart Rate plan is designed for customers who can shift their energy usage to off-peak hours, when electricity is cheaper. This can help reduce their energy bills.
If you're a heavy energy user, the Peak Time Reduction plan might be a better fit. This plan charges higher rates during peak hours, but offers lower rates for off-peak usage.

History
Commonwealth Edison has its roots dating back to 1892, when it was founded as the Chicago Edison Company.
The company's name was changed to Commonwealth Edison in 1964, as it expanded its operations beyond Chicago.
The company's first power plant was built in 1893, and it quickly grew to meet the increasing demand for electricity in the city.
In 1907, Commonwealth Edison began to develop its first hydroelectric power plant on the Des Plaines River.
By 1911, the company had grown to serve over 100,000 customers in the Chicago area.
Commonwealth Edison played a significant role in the development of the electrical grid, with the company's engineers contributing to the standardization of electrical power distribution.
The company's early growth was marked by a series of mergers and acquisitions, including the merger with the Illinois Power and Light Company in 1926.
By the 1950s, Commonwealth Edison was one of the largest electric utilities in the country, serving over 2 million customers.
The company continued to grow and expand its operations, with the construction of new power plants and the development of new technologies.

What They Do
Transmission and Metering teams play a crucial role in ensuring the reliable delivery of electricity to homes and businesses.
They are responsible for maintaining and repairing transmission lines, substations, and other equipment that transport electricity over long distances.
Transmission lines can be up to 500 miles long and carry enough electricity to power thousands of homes.
Metering teams are responsible for reading and maintaining meters that measure the electricity usage of individual homes and businesses.
Meters are typically read every month to determine how much electricity has been used and how much the customer owes.
The data collected from meters is also used to identify energy usage patterns and help customers reduce their energy consumption.
Transmission and Metering teams work together to ensure that the electricity grid is operating efficiently and safely.
Locations
Locations play a crucial role in the transmission and metering of electricity. ComEd, a primary location, is situated at Chicago, IL 60726, US. You can get directions to this location.
ComEd has a physical presence in this location, making it a key hub for their operations.
Corruption Scandal
In 2020, ComEd agreed to pay $200 million following a federal investigation of suspected illegal lobbying, political graft, and sweetheart contract deals.
The investigation revealed that ComEd had a near-monopoly on regional power utility, leading to corrupt practices.
Former ComEd Vice-President Fidel Marquez became the first ComEd executive to be criminally charged for his involvement in the scandal on September 4, 2020.
The charges against Marquez marked a significant step in the investigation, which had been ongoing for several years.
In 2023, four ComEd associates were found guilty on nine counts of bribery conspiracy, bribery, and willfully falsifying the company's books.
These individuals, known as the "ComEd Four", were Anne Pramaggiore, Mike McClain, John Hooker, and Jay Doherty.
They were accused of making efforts to corruptly influence former Illinois House Speaker Michael Madigan.
The convictions of the ComEd Four brought a sense of closure to the investigation, but they also highlighted the need for greater accountability in corporate dealings.
Smart Grid and Technology
ComEd invested $2.6 billion in their "Smart Grid" in 2016 to modernize the electric grid in Illinois.
The Smart Grid plan aims to make the Illinois electric grid stronger and more modern, and to eliminate the need for meter readers.
ComEd lobbyists wrote the law as mandatory Wireless Smart Meter installations to all customers of Illinois, which was passed by the Illinois General Assembly despite opposition from the Attorney General, AARP, and informed Illinois citizens.
ComEd has installed over 3 million smart meters, digital devices that collect information about how much electricity is used, at customer homes and businesses.
These meters send information to ComEd through wireless technology.
ComEd claims that the technology has avoided 7.6 million outages and generated $1.4 billion in societal savings.
Aclara Smart Grid Solutions was awarded the Smart Meter replacement project, with the rollout starting in late 2016 in Chicago.
The project was completed in 2019 in the western edge of the ComEd service territory.
Illinois utility regulators authorized ComEd to establish a 10-year electric microgrid demonstration project on the South Side of Chicago in 2018.
The Bronzeville Community Microgrid Project will connect with a microgrid at the Illinois Institute of Technology, creating one of the first utility-scale microgrid clusters in the nation.

Rates and Choice
You can choose your electric supplier in Illinois, giving you more control over your electric rates. This means you can shop around for a lower rate than what ComEd offers, either through a municipal aggregation program or by opting out and shopping on your own.
ComEd Chicago customers are part of a municipal aggregation program, where the local government shops and chooses the electric supplier for the people. If you want to shop on your own, you can opt out of the program.
The utility is still responsible for repairing a ComEd power outage and delivering electricity, regardless of whether you participate in the municipal aggregation program or shop for your own electric supplier.
Deregulation and Divestiture
In 1996, the prevailing opinion on utilities in the US shifted towards opening as much service as possible to competition on an open market.
The Federal Energy Regulatory Commission issued Order 888, opening access to the national transmission grids, and subsequent orders established an open energy marketplace and set rules for participation in it.
The state of Illinois passed the Electric Service Customer Choice and Rate Relief Law of 1997, which ordered most Illinois electric utilities to provide customers with the option of buying electricity from other suppliers.
The law also reduced base residential electric prices by 15%, with a further 5% decrease effective in 2001, and froze the reduced rates for ten years.
Commonwealth Edison sold its coal-fired generating stations to Midwest Generation in 2000, and its nuclear generating stations to Exelon Nuclear in 2003.
The sale of these generating stations was intended to separate the business of generating and selling power from the business of transmitting and distributing it, but in practice, the holding company still manages and profits from both businesses.
Long-term price agreements went with the sale of the generating stations, under which ComEd was entitled to purchase power below market rates through the end of the rate freeze.

2007 Rate Case
In 2006, Commonwealth Edison had to accommodate both a fully competitive market and the end of its own price agreements with the purchasers of its former generating stations.

The proposed rates would increase residential electric rates sharply, with delivery rates rising by 22% on average. This set the stage for a contentious public debate about the rationale for electric deregulation.
The public outcry was intense, with many claiming that the dramatic rise in rates was proof that deregulation did nothing to help the consumer. The Illinois General Assembly proposed extending the existing rate freeze for several more years.
ComEd responded that extending the rate freeze would bankrupt it, and that it did not have the ability to obtain electricity at a cost that would support the frozen rates. This led to a petition filed with the Illinois Commerce Commission.
The Commission ultimately dismissed the petition, but not before CORE agreed to disclose ComEd's support of it more clearly. This was a result of the Chicago Tribune's reporting that Commonwealth Edison was behind the organization.
ComEd's new rate plan went into effect on January 2, 2007. However, subsequent concerns about the impartiality of the reverse auction process led to the establishment of the Illinois Power Agency.
As part of the compromise plan, ComEd devised a means by which a customer might defer payment of the 22% increase, subject to interest of over 3% on the unpaid portion of the increase.

Compare ComEd Rates to Others
ComEd's price to compare is 6.9 cents for the summer of 2024, and you can use it to compare prices from other providers. This is the base rate you'd pay for electricity from ComEd.
If you shop around, you may be able to find a lower rate than what you get through the utility or through participation in a municipal aggregation program. ComEd Chicago customers are under a municipal aggregation program.
ComEd's rate plan has two parts: delivery rates, which cover the cost of transporting electricity, and the price of the electricity itself. Delivery rates would rise by 22% on average, and the price of electricity would be determined from a reverse auction.
You can opt out of the Chicago municipal aggregation program and shop for your own electric supplier. Just call today to find competitive alternatives to your ComEd electric rates on supply.
