Who they serve
Dominion Energy Ohio (now Enbridge Gas Ohio) is the regulated natural-gas distribution utility for the Cleveland metro and the far-northeast Ohio counties. It is regulated by PUCO. The 2024 transition from Dominion to Enbridge ownership did not change the operational footprint, the emergency response, or the customer phone numbers, but the legal name and the customer-portal branding have shifted to Enbridge Gas Ohio.
The Cleveland metro is split between Dominion / Enbridge and Columbia Gas of Ohio depending on the specific address. Inner-ring suburbs and much of Cuyahoga County are predominantly Dominion; outer-ring suburbs may be Columbia Gas. Always check the utility named on your gas bill before assuming which one to call for a planned project.
Primary metros and cities: Cleveland, Lakewood, Parma, Cleveland Heights, Shaker Heights, Lorain, Elyria, Mentor, Painesville, Youngstown, Warren, Ashtabula.
Counties served: Cuyahoga, Lake, Geauga, Lorain, Ashtabula, Mahoning, Trumbull, Columbiana, Summit (partial).
Major rebate + assistance programs (2026)
Dominion Energy Ohio's residential portfolio leans more toward conservation and bill-assistance than toward the broad appliance-rebate menu Columbia Gas of Ohio offers. Cleveland-area homeowners should check both the Dominion / Enbridge portal and federal / state assistance programs to find the right path. Verify current programs on the utility's own conservation page before assuming eligibility.
- HEAP (Home Energy Assistance Program). Federal-state program administered through the Ohio Department of Development. Income-qualified Ohio households receive a one-time annual heating bill credit. Dominion processes the credit against the gas bill once enrollment is confirmed.
- PIPP (Percentage of Income Payment Plan). Ongoing program that caps qualifying households' monthly utility bill at a percentage of household income. Dominion coordinates with the state to apply the PIPP plan against the gas bill.
- Residential weatherization. Income-qualified Ohio households receive free attic insulation, air sealing, water-heater wraps, and smart thermostats through state-run weatherization providers. Dominion coordinates account-side eligibility but does not perform the install work.
- Customer conservation programs. Periodic Dominion-funded conservation direct-install programs (LED bulbs, water-heater wraps, smart-thermostat distribution) target specific neighborhoods or income tiers. Availability changes year-to-year.
- High-bill investigation. Dominion customer service investigates unusual usage, meter accuracy, and bill disputes. This is often the first call for a customer who suspects a gas leak inflating bills — but for an active suspected leak, always call the emergency line first.
When to call a contractor — not the utility
Dominion Energy Ohio runs the gas main, the meter, and the emergency response. Everything past the meter is contractor work. Cleveland's older housing stock makes the contractor verification step especially important — many homes still have pre-1970 gas piping that needs careful inspection during any modification.
The utility owns this
- Gas-leak emergency response + make-safe (24/7, free).
- Meter installation, replacement, and relocation when load changes.
- Service-line work from the gas main up to your meter.
- Utility-side regulator and pressure regulation.
- Underground line locates (call 811 / OUPS before any digging).
- HEAP / PIPP enrollment processing against the gas bill.

Emergency + outage protocol
The Dominion Energy Ohio / Enbridge Gas Ohio gas-leak emergency line is 1-877-542-2630 (24/7). The response is free.
- Leave the building first. Get every person and pet outside upwind to a safe distance.
- Do not operate anything electric. No light switches, no doorbell, no garage opener, no phone calls inside the building — any spark can ignite leaked gas.
- Call 911 first if urgent — strong odor, audible hissing, anyone feeling lightheaded, fire involved, or you cannot safely leave.
- Call Dominion at 1-877-542-2630 from outside the building. The dispatcher will send a utility crew to locate the leak, shut off the supply if needed, and tag any unsafe equipment.
- Do not re-enter until both responders have cleared the building.
- Schedule the permanent repair with an OCILB-licensed contractor — gas tech for line work, HVAC tech for gas-fired equipment.
Like Columbia Gas, Dominion does not publish an electric-style outage map — gas service interruptions are localized and reported through the same 1-877-542-2630 emergency dispatch flow. Scheduled gas-off events for planned utility work are coordinated with advance notice and a re-light appointment.
Smart home + new construction
New Cleveland construction, major appliance upgrades, and gas-to-electric conversions all involve Dominion Energy Ohio coordination. The contractor handles the customer-side work; Dominion handles the meter and any service-line modifications. The most common Cleveland-area coordination point is the gas-to-electric conversion as homeowners electrify away from gas.
- Smart-meter retrofit. Dominion / Enbridge operates AMR meter reading across the Ohio footprint with phased AMI smart-meter deployment. Replacement is utility-scheduled — no homeowner-initiated retrofit.
- New gas-line install. Pre-construction utility coordination is required. The contractor or builder submits the load and address; the utility schedules the service-line install and meter set.
- Gas-line tie-in for an addition or new appliance. Customer-side work performed by an OCILB-licensed contractor. If the load increase requires a meter upgrade, the contractor coordinates that with Dominion.
- Gas-to-electric conversion. Increasingly common in the Cleveland metro as homeowners switch to heat pumps + induction + heat-pump water heaters. Schedule a meter-pull with Dominion after the contractor caps the customer-side lines. There is typically no charge to pull the meter when the customer-side conversion is complete.
- Cleveland historical-district nuance.Many Cleveland historic neighborhoods (Tremont, Ohio City, Detroit Shoreway, Slavic Village) have older gas piping and stricter permit-and-inspection requirements through Cleveland Building & Housing. Plan extra time and budget for any gas work in these areas.

FAQ
Is Dominion Energy Ohio the same as Enbridge Gas Ohio?
Operationally, yes — the same regulated utility, the same emergency number, the same service footprint. Enbridge Inc. acquired Dominion's Ohio gas distribution business in 2024, and the legal name on bills and the customer portal has transitioned to Enbridge Gas Ohio. Many homeowners still recognize the Dominion East Ohio or Dominion Energy Ohio brand, and the historical references remain in PUCO filings and public materials. For homeowners, the practical reality is unchanged: same service, same number, same response, same regulator.
What number do I call if I smell gas in the Cleveland metro?
Leave the building first — do not turn on lights, do not use a phone indoors, get every person and pet outside upwind to a safe distance. Once you are outside, call 911 if the situation is urgent (strong odor, hissing, anyone symptomatic), and call Dominion Energy Ohio / Enbridge Gas Ohio at 1-877-542-2630 (24/7) to report the leak. The utility's emergency response is free. Do not re-enter the building until both responders clear it.
What rebates and assistance does Dominion Energy Ohio offer?
Dominion Energy Ohio's residential portfolio focuses more on bill-assistance and conservation than on equipment rebates. Core programs include income-qualified energy assistance through Ohio's HEAP and PIPP framework, weatherization assistance for qualifying low-income households, customer-funded conservation programs (audits, direct-install items), and customer-service support for high-bill investigation. Compared with Columbia Gas of Ohio's broader appliance-rebate portfolio, Dominion's rebate footprint is intentionally lighter — verify current programs on the utility's own conservation page.
Does Dominion Energy Ohio install or replace my furnace?
No. Dominion Energy Ohio owns the gas line from the main to your meter, plus the meter and the utility-side regulator. Everything past the meter — house gas piping, shutoffs, appliance hookups, furnaces, water heaters, ranges, dryers — is customer-side and must be installed by a contractor licensed under Ohio Revised Code 4740 (OCILB plumbing license for gas-line and appliance hookups, OCILB HVAC license for gas furnaces and boilers). Cleveland's older housing stock makes the contractor verification step especially important.
Does Dominion Energy Ohio coordinate with Columbia Gas of Ohio?
Indirectly. The Cleveland metro footprint has historically been split between the two utilities depending on the specific neighborhood — Dominion (now Enbridge Gas Ohio) covers much of Cuyahoga County and the inner-ring suburbs, while Columbia Gas of Ohio covers parts of the outer ring and the broader region. Both utilities are regulated by PUCO and respond to gas-leak emergencies independently. Check your gas bill for the actual utility on file for your address before assuming which one to call for a planned project.
Do I need a permit for Cleveland gas-line work?
Almost always. Cleveland and the inner-ring suburbs have strict mechanical and plumbing permit requirements for any new gas line, line extension, regulator change, or appliance addition. Like-for-like replacement of a single appliance often does not require a permit but always requires a leak test. The City of Cleveland Building & Housing department, the Cuyahoga County building department, and individual suburb building departments all enforce permits — your OCILB-licensed contractor handles the permit and the inspection.
