What Spark Energy does

Spark Energy is an independent retail electricity and natural gas supplier founded in 1999 and headquartered in Houston, Texas.

Its service is delivered via the local utility's distribution infrastructure, with Spark Energy appearing as a line item on the customer's consolidated utility bill.

Distribution partnerships include Via Energy Solutions for residential solar, and operational integrations with utilities such as Delmarva Power.
