What does National Grid do for you?
Pick your part of New York to see whether National Grid handles your electricity, your gas, or both.
Electricity + gas delivery
National Grid is your electric and gas delivery utility (legacy Niagara Mohawk). Pick any NY-certified ESCO for supply; National Grid still delivers and sends the bill.
Natural gas delivery only
National Grid (legacy Brooklyn Union Gas / KeySpan) delivers your natural gas. Your electricity utility is Con Edison.
Natural gas delivery only
National Grid (legacy KeySpan Gas East) delivers your natural gas. Your electricity utility is PSEG Long Island.
Two utilities in one company
National Grid grew through acquisitions, and in New York it inherited two completely different territories. The footprints do not overlap, the fuels are different, and even the emergency phone lines are different.
Upstate New York
Electric + gas delivery
National Grid is the electric delivery utility for most of upstate New York and also delivers gas in many of those same cities. This is the old Niagara Mohawk footprint.
- ·Service area: Buffalo, Niagara Falls, Rochester suburbs, Syracuse, Utica, Albany, Schenectady, Troy and most of the Hudson Valley north of Westchester;
- ·Customers: roughly 1.6 million electric, about 600,000 gas;
- ·Wholesale market: NYISO Zones A, B, C, D, E, F (structurally cheaper than NYC).
Electric emergency: 1-800-867-5222.
Downstate New York
Natural gas delivery only
In New York City and on Long Island, National Grid is only the gas utility. It does not deliver electricity downstate. This is the old KeySpan / Brooklyn Union Gas footprint.
- ·NYC gas (Brooklyn, Queens, Staten Island): legacy Brooklyn Union Gas;
- ·Long Island + Rockaways gas: legacy KeySpan Gas East;
- ·Electricity downstate: Con Edison in NYC, PSEG Long Island on LI;
- ·Customers: roughly 1.8 million gas across NYC + LI.
Gas emergency (NYC + LI): 1-800-892-2345.

What National Grid does NOT do
National Grid is the wires-and-pipes company. It is not your retail energy supplier unless you have explicitly stayed on the default service. Knowing the difference saves you money and a lot of phone-call ping-pong.
National Grid DOES
- ·Own and operate the poles, wires, substations, gas mains and meters;
- ·Send you the bill (in most setups) and read your meter;
- ·Restore power after an upstate outage or gas leak;
- ·Charge a regulated delivery rate set by the NY PSC.
National Grid does NOT
- ·Sell you the kWh or therms themselves (that is the ESCO or default supply);
- ·Set the supply price you see on the bill;
- ·Deliver electricity in NYC (Con Edison) or on Long Island (PSEG Long Island);
- ·Cold-call you to switch suppliers (that is a scam: see our scams guide).
Recent regulatory action affecting National Grid customers
National Grid's delivery rates, gas rates and retail-supplier rules are set by the New York Public Service Commission. Two recent decisions matter directly to anyone on a National Grid bill.
PSC ESCO settlement (April 16, 2026)
The Public Service Commission approved a settlement tightening rules on Energy Service Companies operating in National Grid (and other utility) territories: stricter marketing disclosures, mandatory price guarantees on residential offers, and easier exits for customers stuck on auto-renewed variable rates. Check your latest National Grid bill: if your ESCO has been quietly above the default supply rate, you are now in a stronger position to switch.
Energy Affordability Program (EAP)
National Grid runs a NY-PSC-mandated income-qualified discount on the delivery portion of the bill. If your household receives HEAP or EAP benefits, SNAP, SSI or similar, you may automatically qualify. Apply through the same intake that handles HEAP at otda.ny.gov/programs/heap.
Verify the most recent figures and program details with the NY PSC (dps.ny.gov) and the OTDA HEAP site before applying.
6 things every National Grid customer should know
Your account number is region-specific
Upstate accounts (Niagara Mohawk legacy) look different from KeySpan / Brooklyn Union accounts. When you call, the agent first asks which region you are in: upstate, NYC or Long Island. Have your zip code and account number ready.
Upstate kWh is cheaper than NYC
The NY state residential average sat at 28.55 ¢/kWh in March 2026 (EIA). National Grid upstate zones (A, B, C, D) clear well below that because NYISO wholesale prices in Buffalo and Syracuse run structurally lower than Zone J (NYC). If you moved from NYC, your delivery rate dropped too.
Delivery and supply are separate
National Grid sets the delivery line (regulated by the PSC). The supply line is either default supply or an ESCO of your choice. See our bill guide for a line-by-line breakdown.
Outages and gas leaks have different numbers
Upstate electric outage: 1-800-867-5222. Gas leak in NYC or LI: 1-800-892-2345. Do not call the general line in an emergency.
Budget Billing smooths gas spikes
Gas bills can swing 4x to 5x from summer to mid-winter in upstate NY. National Grid's Budget Plan averages 12 months of usage into a flat monthly amount, with a reconciliation at year-end.
Help is available before shutoff
If you are behind on a bill, call National Grid before your service is at risk. HEAP, EAP and National Grid's Care & Share Energy Fund can cover part of the arrears. The PSC's cold-weather rule also restricts winter shutoffs.

6 expensive mistakes National Grid customers make
Mistake 1
Calling your ESCO during an outage
ESCOs sell you the energy; they do not own the wires. In an upstate electric outage, call National Grid at 1-800-867-5222. Calling the ESCO just wastes daylight.
Mistake 2
Not switching off variable auto-renew
Many ESCO contracts roll a low introductory fixed rate into a monthly variable that quietly drifts well above the default supply. Set a calendar reminder for two months before contract end and re-shop.
Mistake 3
Confusing upstate electric with downstate gas
A Brooklyn renter who calls National Grid for an electric outage gets routed to Con Edison; a Syracuse homeowner who calls KeySpan gets routed back. Different territory, different fuel, so make sure you have the right line.
Mistake 4
Trusting a "National Grid representative" at the door
National Grid never sells you supply door-to-door. If someone in a branded vest asks to see your bill or pressures a same-day switch, it is an ESCO sales agent (often a scam). Close the door and call the official number on the back of your bill.
Mistake 5
Waiting until the disconnection notice
By the time you receive a shutoff notice, your options are narrower and your credit harder to protect. Call National Grid the first time you cannot pay in full; deferred payment agreements, EAP and HEAP all exist precisely for this moment.
Mistake 6
Comparing only the rate, not the unit total
A 9.5¢ ESCO offer with a $9.95 monthly fee is more expensive than a 10.5¢ default if you use under 1,000 kWh a month. Always multiply by your actual annual usage before signing.
Frequently asked questions
It depends on your zip code. Upstate (Buffalo, Syracuse, Albany, the Capital Region, most of the Hudson Valley north of Westchester), National Grid is your electric and gas delivery utility. In New York City and on Long Island, National Grid delivers only natural gas: electricity in NYC is Con Edison, and electricity on Long Island is PSEG Long Island.
Upstate, call National Grid 24/7 at 1-800-867-5222. If a wire is on the ground or anyone is hurt, call 911 first, then the utility. In NYC, call Con Edison. On Long Island, call PSEG Long Island.
Leave the building first. Do not flip switches, light matches or use a phone inside. Once outside, call the 24/7 gas emergency line: 1-800-892-2345 in NYC or on Long Island. From upstate, the same number reaches the gas emergency desk. Then call 911 from a safe distance if needed.
Yes. New York has had retail energy choice since 1998. National Grid still delivers the energy and sends the bill; you can pick any ESCO licensed by the NY PSC for the supply portion. After the April 2026 PSC settlement, ESCO offers must include clearer disclosures and a guaranteed price for the initial term.
NYISO splits the state into wholesale zones. National Grid upstate territory sits in Zones A, B, C and D, which clear at lower wholesale prices than Zone J (NYC). Lower wholesale energy + lower urban-infrastructure cost = a smaller delivery rate on the upstate bill. NY's March 2026 residential average was 28.55¢/kWh (EIA); upstate runs structurally lower than that average.
Yes. The Energy Affordability Program (EAP) cuts the delivery portion of the bill for income-qualified households. If you already receive HEAP, SNAP, SSI or Temporary Assistance, you are usually auto-enrolled. Apply at otda.ny.gov/programs/heap or call your local HEAP office.
Two big sections. Delivery (set by National Grid via PSC-approved tariffs): customer charge, distribution per-kWh or per-therm charge, transition adjustments, system benefits charge. Supply (set by default supply or by your ESCO): the cents-per-kWh or dollars-per-therm rate for the actual energy. See our bill-by-bill walkthrough.
National Grid's upstate Niagara Mohawk subsidiary and its downstate gas subsidiaries (KEDNY for NYC, KEDLI for Long Island) file multi-year rate cases with the NY PSC on a rolling basis. Check the latest PSC orders at documents.dps.ny.gov for the current effective delivery rates in your zone.
