To keep prices competitive, Washington diversifies its energy portfolio. The greatest contributor is hydroelectric power, which generates close to 7,700 gigawatts per hour (GWh) annually. Other significant sources of electricity are nuclear (812 GWh), natural gas (290 GWh) and coal (192 GWh). Renewables, which account for 912 GWh, include wind, solar and geothermal. As a result, the state offers electricity at a 35 percent discount from the national average.
Generally, the generation of electricity is unrelated to anything on your bill. Power plant companies generate electricity and sell it to utilities as well as retail electricity providers in deregulated areas. The electricity is then resold to you, the customer. Transmission and distribution is taken care of and charged to you by your utility, regardless of what company supplies the electricity. These charges are separate from the supply portion of your bill.
Many people are aware that Iceland has the cleanest energy in the world by far. The island-nation generates 100% of its electricity from renewables such as hydroelectric and geothermal sources, and it’s also flirting with wind power. What those same people might not realize, however, is that this results in some of the cheapest electricity in the world.
As you shop, you’ll see the rates advertised in terms of kilowatts per hour (kWh) — the energy used to power 1,000 watts for one hour. According to the U.S. Energy Information Administration, the average price per kWh for electricity in Pennsylvania is 14.52 cents, while the Public Utility Commission's “price to compare” currently hovers around 8.0 cents. Clearly, there’s a lot of price variety out there. And, given the hundreds of providers doing business in Pennsylvania, exploring electricity options can be pretty toilsome.

The main difference between a provider and TDSP is that a TDSP is in charge of delivering electricity supply to a consumer's home or business. Contact your local TDSP for emergency situations such as hazardous electrical wires, storm alerts and power outages. Also, AEP offers McAllen residents and business owners with storm safety tips and service request information. Contact the TDSP at 1-877-373-4858 for electrical safety issues and 1-866-223-8508 for outage emergencies.

Switching electricity supplier could shave pounds off your bills. But it’s not always about how much hard cash you could save. You might be fed up with poor customer service, you might want greater visibility of your usage through an app or you might want to choose your supplier based on their green credentials, or whether they supply a smart meter.
