How Energy Supply Works in Maryland

  • Your utility continues delivering energy, maintaining lines (electricity), pipes (natural gas) and handling outages
  • A supplier provides the electricity or natural gas supply portion of your service
  • Choosing a supplier does not change reliability or emergency response



How Electricity & Natural Gas Gets to Your Business

It starts with energy supply being generated and then bought by suppliers in the market. You pick a plan for your business and the utility delivers the electricity and/or natural gas to your location, regardless of who your supplier is.

How Switching Suppliers Works

Switching suppliers in Maryland typically involves:

  • Viewing pricing and plan types
  • Selecting a supply plan (supply rate + term length)
  • Deciding when you want to switch
  • Signing your new contract

When you switch suppliers, there are no service interruptions or equipment changes and your utility remains the same.
