Pepco Maryland Customer bills will increase starting on April 1, 2022, and as authorized by the Maryland Public Service Commission (PSC), will be partially reduced by certain tax benefits. With the rate adjustment and offsets approved by the PSC, typical residential electric bills will increase by $3.48 per month as compared to last year. See pepco.com/MYPMD for details.
Electricity, like the printing press or the Internet, is what is known as a "general purpose" technology—an innovation that revolutionizes society and forms the foundation of modern life as we know it. When you think of all the ways we use electricity every day—riding an elevator, heating our food, charging our phones—it becomes difficult to imagine a world without it. But what, exactly, is electricity? And how has it come to play such a central role in our lives?
Electricity is a naturally occurring phenomenon that people have learned to harness through a series of creative inventions. For modern commercial usage, electricity is generated at power plants by burning nonrenewable fossil fuels such as coal, natural gas, and petroleum, or by capturing the energy of renewable sources such as the wind, sunshine, and water. Each of these processes converts energy from its original source into usable electricity, which is carried away from the power plant along high-capacity transmission wires and into the network of power lines known as the electric grid.
Before it reaches our homes, the electricity first travels to neighborhood substations and then along smaller distribution lines to electrical transformers (either underground or high on telephone poles), which reduce the strength, or voltage, of the electricity to a level that is safe to use for our everyday needs. When you plug a device into an outlet, you are tapping into the electric grid – electricity flows into one prong, through the device, and out the other prong, completing a circuit that provides the energy your phone charger, microwave, or television needs to function.
Before electricity, lighting was provided by candles and gas lamps, our food was stored in iceboxes, and fireplaces were the main source of heat in our homes. Although people have been aware of electric forces since Ancient Greece, the term "electricity" was only first used in 1600. Since then, many familiar names – Benjamin Franklin, Thomas Edison, Nikola Tesla – have contributed to our understanding of electricity, making it impossible to give credit to just one or two inventors. Benjamin Franklin, in his famous 1752 kite experiment, discovered that lightning is a naturally occurring source of electricity. Italian physicist Alessandro Volta invented the electric battery in 1800, providing us with the first controlled, usable source of electricity. Throughout the 19th century, many important scientists contributed to our knowledge of electricity – the work of Michael Faraday led to the invention of the electric generator, Thomas Edison’s light bulb led to the first widespread commercial use of electricity, and Nikola Tesla’s experiments with alternating current allowed electricity to be transmitted across vast distances.
Building on all of these innovations, electricity started playing a greater role in everyday life. Cleveland, Ohio became the first city to use electric lamps for public lighting in 1879, and that same year San Francisco’s California Electric Light Company, Inc. became the first company to sell electricity to customers. Small electrical stations capable of powering a few blocks were in place in many American cities by 1890, and by the time America’s first alternating current power line – the same kind of power line we use today – opened in 1893 between Folsom and Sacramento, California, the country’s electricity industry was rapidly expanding. Pepco began supplying electricity to the Washington, DC area in the 1920's, and by 1950 nearly all Americans, both urban and rural, were plugged into the electric grid.
Just because electricity is now a common feature in our lives doesn’t mean that innovation has stopped – or even slowed down.
The introduction of smart grid technology into the traditional power grid is allowing customers to better track and manage their electricity usage and costs with features such as smart meters that improve efficiency, sustainability, and reliability. We are committed to building the most advanced and reliable power grid. Our Blueprint for the Future outlines how we plan to harness the full potential of smart grid and related technologies, passing on savings and benefits directly to our customers.
Just as the commercial use of electricity started with light bulbs and later expanded to many other devices and appliances, transportation is electricity’s 21st century new frontier. Battery-powered electric cars, currently being produced by more than ten major automakers, can be plugged into typical electrical outlets to recharge. These vehicles produce drastically lower emissions than gas-fueled cars and, as the cost of gas continues to climb, present a much cheaper alternative for both individual customers and our national economy. It is estimated that the cost of powering an electric car for the same distance as a gallon of gasoline could be less than one dollar. We recognize the enormous potential of electric cars and have moved ahead with implementing an innovative Plug-In Vehicle Charging Pilot Program and are gradually converting our service fleet to electric vehicles.
Cars are not the only mode of transportation benefiting from innovations in electricity. Rail transport, especially in the dense Northeast Corridor from Washington to Boston, stands to improve in speed, safety, and reliability as advanced electric wires are installed that deliver greater amounts of energy to train engines in a more efficient manner. Imagine Washington to New York City in 1.5 hours – with electricity, it’s possible.
Although 91% of electricity in America still comes from nonrenewable sources, advances in solar, wind, geothermal, biomass, and hydropower are quickly making renewable energy a more realistic option. Electricity from abundant nonrenewable resources has traditionally been less expensive to produce, but as the global demand for electricity increases, renewable resources promise to revolutionize the energy industry into one that has minimal impact on our environment, is less susceptible to changes in the price of resources such as petroleum and provides a reliable, infinite source of electricity for a growing population.
We are committed to increasing the amount of renewable energy sources used to generate electricity for our customers. Today, that percentage is small due to the lack of available renewable resources. However, we are committed to seeing that percentage grow – up to 20% by 2020 in some states – because renewable energy has the potential to provide us with cleaner air, a more diverse energy portfolio and less dependence on foreign fossil fuels.
Using progressive investment in tested and reliable renewable energy solutions, we aim to reduce our use of fossil fuels in the near future, as well as the greenhouse gasses that generating energy from fossil fuels produces, all while keeping energy affordable and dependable for our customers.
There are four main areas that make up the cost of your energy:
