Duke Energy's earliest incarnation in the electricity industry was as the Catawba Power Company. Created in 1900 by Dr. Walker Gill Wylie, the goal was to install a series of hydroelectric power plants on the Catawba River. Wylie convinced the wealthy industrialist, James Buchanan Duke, to invest in the project as a way of powering his textile mills. In 1905, the company was reorganized as Southern Power Company. Through merger and acquisitions, it expanded quickly; reorganizing in 1927 to form Duke Power, the precursor to Duke Energy.

Duke Energy's involvement with Ohio natural gas goes back to 1837 when a group of Cincinnati investors founded the Cincinnati Gas, Light & Coke Company to produce coke for iron works and then sell the coal-gas by-product to the city residents for street lighting. They eventually secured exclusive gas franchise rights and thereafter residential demand for coal gas quickly blossomed.

In 1877, former Union General Andrew Hickenlooper became the company president. Hickenlooper had very dim views on electricity and so-called "natural gas" from West Virginia. Though he would eventually reorganize the firm in 1901 into the Cincinnati Gas & Electric Company (CG&E), he fought ceaselessly to protect the company's coal gas monopoly. For nearly 26 years, he prevented cheap natural gas from entering Cincinnati. But in 1903, the ailing old general finally left his post. He died the following year.

Smelling a ripe opportunity, a confederation of entrepreneurs formed the Columbia Corporation with the intent to control "public service corporations, especially in Cleveland & Cincinnati, OH." Rebranded in 1909 as "Columbia Gas & Electric" the company inked a deal to supply CG&E with natural gas from West Virginia via its new 183 mile-long pipeline. Residents soon saw their gas rates cut in half. Then in 1911, CG&E became a subsidiary of Columbia Gas & Electric. This relationship only lasted until 1948 when SEC antitrust litigation forced Columbia to set CG&E free.

Left on its own, CG&E expanded its service area into Indiana and Kentucky by purchasing other former Columbia Gas & Electric subsidiaries, including the Union Light, Heat & Power Company (ULH&P). Though the post war years were rocky, CG&E expanded operations in the region. By the 1990s, the company was leveraging its access to gas suppliers and pipelines to improve generation. But as demand continued increasing even further, so too did the need to build even more generation. The solution came in 1994 when CG&E and ULH&P merged with Indiana-based PSI Energy to form Cinergy. The new company served 1.5 million electric customers and about 500,000 gas customers in Ohio, Indiana and Kentucky.

Meanwhile, by 1997, Duke Power had wooed and won the natural gas giant, PanEnergy, for $7.7 billion and changed its name to Duke Energy. Looking to expand further into natural gas fueled power generation, it bought Cinergy in a $9 billion all-stock deal in 2005.

Duke Energy Corporation now supplies electricity to approximately 7.4 million customers and distributes natural gas to more than 1.5 million customers in the Carolinas, Kentucky, Tennessee, and Ohio. As a responsible corporate citizen, Duke Energy invests in its communities and help nature and wildlife thrive through its foundation providing grants to charitable nonprofit organizations in four main areas: Environment, Economic Development, Education and Community Vitality.

Ohio utilities are limited in the amount they can charge for a deposit. Customer deposits can be no more than the estimated average 30-day bill plus 30%.

Understand Duke Delivery and Supply Charges

In Ohio, residential customers pay for both the cost to deliver their electricity and natural gas as well as as the commodity cost for the amount of supply that they use.

  • Delivery Charges are fixed rate charges (tariffs) representing the cost of transmitting electricity or natural gas to your home via Duke Energy's power line and pipeline networks. The charges cover Duke's local infrastructure operating costs, maintenance, and ensure them a profit. Other usage-based charges are small costs from riders to fund projects, cover fees, etc. Duke's delivery charges must be approved by Public Utilities Commission of Ohio (PUCO). All Duke customers pay the same set Delivery rates (one for electricity, one for natural gas) no matter who supplies their energy.

  • Supply Charges represent the price for the amount of energy supply that you use. Customers can choose Duke's "Price to Compare" for electricity supply or their "Gas Cost Recovery" for their natural gas supply. However, because of Ohio's Energy Choice program, customers are free to also choose energy from competitive retail electricity or natural gas suppliers.
  • Understand Duke PTC and GCR Charges

    PUCO requires Duke Energy to provide both electricity and natural gas supply at a default rate to customers in their service territory who don't shop for a retail supplier. Implementing both the PTC and GCR default rates is overseen by PUCO as they repesent costs that are passed directly through Duke onto consumers without mark up.

    Price to Compare (PTC)

    The PTC default rate represents the actual price the utility pays for the electricity. It includes not only the price to generate the electricity but also the cost to transmit it from power stations over high tension power lines to Duke's local electrical switch yards. From there, the electricity is distributed throughout Duke's local electrical grid for delivery to homes.

    PTC rates are determined during periodic auctions for set periods of the year. Therefore, PTC rates will only last for a few months. That means these electricity rates can vary seasonally; low some months, higher the next.

    Duke Energy Current PTC Residential Rate: 5.340 cents per kWh, expires 4/30/2021

    Gas Cost Recovery (GCR)

    The GCR default rate represents 100% of Duke Energy's gas costs incurred to purchase and deliver natural gas to its system. Duke Energy Ohio is the only natural gas utility in Ohio with choice that uses a traditional GCR process for default service.

    The GCR is PUCO-approved default rate for the natural gas supply that you can select if you don't want to shop for retail supplier. The drawback with the GCR gas supply price is that it varies from month-to-month. Sometimes it's low, sometimes it's high.

    Duke Energy Current GCR Residential Rate: 0.339 cents per ccf, expires 2/29/2020

    NOTE: Some Ohio municipal utilities purchase energy for their local residents. Usually residents need to pay an opt-out fee if they don't want their electricity or natural gas service to be aggregated. Check with your local government to learn how you might be effected.

    How Much Do Duke PTC and GCR Charges Cost?

    Both the Duke PTC and GCR rates change periodically during the year. That makes it important for consumers to know and understand how much they are paying for their electricity and natural gas in any one month.

    How much is the Duke PTC rate?

    PUCO estimates that the average Ohio residence uses an average of 750 kWh each month. Therefore, an average PTC bill roughly breaks down like this:

    Rate per 750 kWh Used Monthly Customer Charge Total
    PTC Supply Rate 5.340 cents 0 $40.05
    Monthly Distribution Charges $0.031482 per kWh $6.00 $29.61
    Total Bill $69.66

    How much is the Duke GCR rate?

    According to PUCO's estimates, the average Ohio home uses roughly 100 ccf per month.

    At an average monthly usage rate of 100 ccf, a Duke GCR bill looks approximately like this:

    Rate per 100 ccf Used Monthly Customer Charge Total
    GCR Supply Rate 0.339 cents 0 $33.90
    Monthly Distribution Charges $0.032728 per first 400 ccf* $33.03 $36.30
    Total Bill $70.20

    * Consumption in excess of 400 ccf increases the residential rate to $0.097278 per ccf.

    Understand Ohio Energy Choice

    Ohio natural gas consumers are free to choose their own competitive retail electricity or natural gas supplier. These alternative suppliers shop deals with different producers on the wholesale market to offer competitive rates. As such, their rates are not controlled by PUCO. This way, retail suppliers are able to offer competitively priced fixed rate plans for a variety of term lengths.

    Though it can seem confusing, shopping electricity and natural gas plans is an easy process. The trick is finding the one that meets your needs. That's why retail energy suppliers in Ohio offer two types of plans:

  • Fixed Rates have their price rate set for the same price over the term of the contract. That means customers can count on stable energy rates on plans lasting from 6 to 36 months. However, many fixed rate plans come with early cancellation fees for breaking a contract early.

  • Variable Rates Want to avoid getting tied to an electricity or natural gas plan for months or years? Then choose a variable plan. Variable plan rates on these contracts can change from month to month depending on the price of the electricity or natural gas supply. But while there's no contract, there's nothing to prevent your rate from going up one month or down the next. However, these plans don't have any termination fees and this allows customers the flexibility to shop for new rates and switch to better deals without paying any penalty.

  • Understand Your Energy Usage and Your Duke Bill

    While your energy usage habits are unique to you, any Ohio native will tell you, winters can be bitterly cold and summers can be torridly hot. In the east north central region of the U.S., up to 55% of an average home's energy usage goes to space heating.

  • Though nearly one-fourth (24.3%) of Ohio homes use electricity for space heating, natural gas warms 65% of homes in the state.
  • Ohio residents use an average of 6% to 12% of their total annual energy costs for air conditioning.
  • The remainder of energy use goes to water heating, refrigeration, lighting, electronics, clothes dryers, cooking, and small appliances.

  • Want to learn more about your home energy usage? Duke Energy customers can request up to 24 months of their electric usage plus other relevant information free of charge.

    The most effective way to cut your energy bills is to reduce your usage by sealing your doors and windows against winter and summer drafts. Adding insulation to your attic, sealing and insulating your basement, and purchasing a programmable or smart thermostat also improve your home's energy efficiency and help cut your electric bills. Your utility company can provide a wealth of resources and offers programs to help you improve your home's energy performance.

    Understand Your Duke Bill
