The short answer
To switch your gas supplier in a deregulated state (OH, PA, MD, IL, NY, parts of NJ, MA, CT, RI), enter your ZIP on your state gas-switching portal, compare licensed suppliers against the utility default rate, and e-sign a fixed-rate offer. Same utility delivers gas through the same pipe. New rate kicks in at next utility meter read (30-45 days). No service interruption.
Switching natural gas suppliers in a deregulated state works exactly like switching electricity suppliers — same EDI handshake, same utility-keeps-the-pipe mechanics, same 30-45 day activation timeline. The only differences are unit (therms instead of kWh), portal (state-specific gas portal), and seasonal pattern (winter spikes for gas mirror summer spikes for electricity). This guide walks the gas-switching workflow end-to-end and identifies the deregulated-gas states.
Where gas supplier choice exists
Natural gas deregulation parallels electricity deregulation but with a slightly different state map. Full residential gas choice is available in Ohio, Pennsylvania, Maryland, Illinois, New York, parts of New Jersey, parts of Massachusetts, parts of Connecticut, and parts of Rhode Island.
In each deregulated state, the utility owns the local distribution pipeline (the pipe from the city gate to your meter). Gas suppliers buy molecules upstream and resell to end-customers at a per-therm rate. The supplier change happens at the account-of-record level only.
Each state has its own gas-switching portal: PA Gas Switch (PA), Apples to Apples (Ohio, doubles as electric portal), MyGasChoice (MD), Plug In Illinois (IL), and others. Look up your state PUC for the official portal.
The 5-step gas-switching mechanic
Step 1: ZIP code identifies your utility. PECO Gas in Philadelphia, Columbia Gas of Ohio in Columbus, Washington Gas in DC suburbs, ConEd Gas in NYC. Each utility has its own default supply rate and its own list of licensed competitive suppliers.
Step 2: read the supplier offers. Like electricity, the cleanest residential gas profile is fixed rate, 12 or 24 month term, $0 monthly customer charge, $0 early-termination fee, no introductory period.
Step 3-5: e-sign, EDI 814, switch effective at next meter read. Same as electricity. Total wall-clock time: 5-10 minutes for you, 30-45 days until the new rate appears on the bill. The how-to-switch-energy-supplier guide walks the EDI mechanic in detail.

When to lock — gas-specific timing
Gas wholesale prices peak December-February (heating demand) and trough April-October. The cleanest gas-lock window is May through September — far enough ahead of the winter spike that suppliers can hedge favourably.
Locking in October or November is suboptimal — the winter spike is already priced into the curve. Locking in February is the worst time of year — peak spike, suppliers have less inventory.
For commercial gas accounts, the same logic applies but September is historically the cheapest single month. Bundles of 5+ gas-using sites clear best in September RFPs. The why-is-my-gas-bill-so-high-in-winter guide walks the seasonal price pattern.
Recap
Bottom line
Switching natural gas suppliers in deregulated states works exactly the same way as switching electricity suppliers — same EDI handshake, same 30 to 45-day activation timeline, same utility-keeps-the-pipe model. The differences are unit (therms vs kWh), portal (state-specific), and seasonal pattern (winter peak instead of summer peak).
For most households in deregulated gas states (Ohio, Pennsylvania, Maryland, Illinois, New York, parts of New Jersey, Massachusetts, Connecticut, Rhode Island), the optimal play is locking a 12 to 24-month fixed per-therm supply rate in shoulder season (May through September), well before the winter wholesale spike. The why-is-my-gas-bill-so-high-in-winter and how-to-read-your-natural-gas-bill guides cover the supporting context.
