Sparks of Kindness

Spark Energy seeks to give back to the communities we serve. Here are a few examples of our efforts to help:

  • St. Baldricks: Spark Energy partnered with Fox Chicago Schools to raise funds for the St. Baldricks Foundation, which is known for rallying volunteers to raise money for pledging to shave their heads in solidarity with children fighting cancer.
  • Relay for Life: Spark Energy donated $5,000 to the American Cancer Society’s annual fundraising drive. And for every person who signed up using a special promo code, Spark Energy donated $25 to the cause.

Can You Choose A Different Electric Company or natural gas supplier?

Some Illinois residents and businesses seem a bit uncertain about whether they can select a different electricity and natural gas provider. In reality, it’s very simple. For electricity, Commonwealth Edison, the main electric company that has served much of Illinois in the past, is the electric utility – this means they own and maintain the infrastructure that brings electricity to your home. However, you are now free to select a different company, such as Spark Energy, to supply that power to the utility.

With Natural gas in Illinois, deregulation is similar. Utilities such as Nicor, Peoples, and Peoples North Shore, provide the infastructure, and Spark Energy provides the natural gas supply.

When you switch to Spark Energy, the utility is still responsible for delivering the energy to your home, and you’ll still call them in case of an emergency or outage. And you’ll still be billed by the utility– Spark Energy will appear as a line item on the bill.

That’s it. One bill from the same utility, but you could pay a lower rate for energy.
