Current Rate Schedules
KEDNY gas bills separate a regulated delivery charge (set by NYPSC tariff service classifications) from the gas supply charge (utility default or competitive ESCO). Commercial and industrial customers fall under non-residential service classifications: SC 2-1 (non-residential non-heating), SC 2-2 (non-residential heating), SC 3 (multi-family), SC 4A (high load factor), SC 4B (year-round air conditioning), SC 7 (seasonal off-peak), SC 21 (large transportation, tiered by demand), and SC 22 (non-firm demand response). Delivery rates use a declining-block structure (a fixed minimum charge for the first block of therms plus per-therm charges that decline with volume and vary by season). Verified per-therm figures below come from the publicly posted KEDNY rate summary; current effective sheets are in the KEDNY Gas Delivery Charges tariff (effective December 1, 2025). The three-year rate plan (2024-2027) raises total bills by about 10.5% per year on a levelized basis.

Rate Recommendations by Use Case
Commercial building / restaurant (non-heating or heating)
Most commercial gas accounts fall under SC 2-1 (non-heating) or SC 2-2 (heating), billed on a declining-block delivery rate plus a separate gas supply charge. Compare ESCO supply offers against the utility default to manage the commodity portion of the bill.
Delivery is fixed by tariff, so the controllable lever for these customers is the gas supply price — shopping ESCOs and managing seasonal usage drives savings.
- Pull 24 months of usage from My Account to benchmark seasonal consumption
- Compare ESCO offers on the authorized-suppliers list before signing
- Enroll in Green Button Connect to let a consultant analyze usage
Multi-family / co-op building (master meter)
Master-metered multi-family buildings take SC 3 service, with a fixed first-block charge (~$39.51 for the first 3 therms) plus declining per-therm delivery charges. Benchmarking and efficiency upgrades reduce volumetric cost.
SC 3 is volumetric with a modest fixed minimum, so reducing total therms (insulation, boiler efficiency) directly lowers the bill, while ESCO shopping addresses the supply charge.
- Track building-level therms month over month with the Excel export
- Evaluate boiler/heating efficiency upgrades to cut volume
- Consider an ESCO fixed-price contract to hedge winter supply costs
Large steady high-volume facility (high load factor)
Large facilities with steady, high-volume gas use should evaluate SC 4A High Load Factor service, which trades a high fixed first-block charge (~$250 for the first 10 therms) for low declining per-therm rates — favorable when consumption is high and consistent.
The high fixed charge is amortized across large volume, so the low per-therm rate makes SC 4A cheaper per therm than general commercial classes for high-load-factor users.
- Confirm your load factor justifies the high fixed minimum vs. SC 2-2
- Use Energy Profiler Online to document load shape for the rate analysis
- Maintain steady consumption to maximize the high-load-factor advantage
Large transportation customer buying gas from an ESCO (1-50 MW)
The largest customers take SC 21 transportation service (Rate 1 <1 MW, Rate 2 1-5 MW, Rate 3 5-50 MW), buying gas commodity from an ESCO while National Grid transports it. Rate 3 adds a demand charge per therm of maximum daily quantity (~$4,927.82/therm MPDQ).
At this scale the demand component (MPDQ) and ESCO commodity price dominate; managing peak daily demand and negotiating ESCO supply are the biggest levers.
- Manage maximum daily quantity (MPDQ) to control the demand charge on Rate 3
- Run a competitive ESCO procurement for the commodity portion
- Use EDI / GBCMD data feeds to monitor nominations and balancing
Interruptible facility able to curtail on demand
Facilities that can switch fuels or curtail gas use may qualify for SC 22 non-firm demand-response service, which offers lower delivery costs in exchange for interruptibility.
Non-firm service is cheaper than firm delivery, so customers with backup fuel or curtailable load can lower delivery cost by accepting interruption risk.
- Confirm backup fuel capability before electing non-firm service
- Model the savings vs. interruption risk for your operations
- Coordinate nominations and balancing via your ESCO and EDI feeds
Historical Rate Trends
KEDNY's current delivery rates are set under a three-year rate plan approved by the NYPSC in 2024 (Cases 23-G-0225/0226, Joint Proposal filed April 9, 2024). The plan runs from April 1, 2024 through March 31, 2027 and raises total customer bills by about 10.5% per year on a levelized basis for KEDNY.
August 15, 2024
NYPSC approved the Joint Proposal establishing KEDNY's three-year gas delivery rate plan (April 1, 2024 - March 31, 2027) with levelized total-bill increases of about 10.5% per year (Cases 23-G-0225/0226).
+10.5%/yr (levelized total bill)December 1, 2025
Updated KEDNY Gas Delivery Charges tariff sheet posted (effective December 1, 2025), reflecting the Rate Year 2-3 levelized delivery charges under the approved plan.
Per approved levelized scheduleOverall trend: Rising. The 2024-2027 rate plan implements levelized total-bill increases of roughly 10.5% per year for KEDNY, driven by net plant and depreciation, O&M, property taxes, and amortization of regulatory deferrals. Delivery revenue increases of about $256.9M (RY1), $287.5M (RY2), and $320.1M (RY3) were authorized. Supply (commodity) costs pass through separately and vary with market gas prices.
Next expected change: Annual rate-year adjustments take effect each April through the plan term; the next reset follows the end of the current plan on March 31, 2027 (subject to a future NYPSC rate case).
Cost Optimization Strategies
Because KEDNY delivery rates are fixed by tariff, C&I cost optimization centers on (1) managing the competitive gas supply (commodity) charge through ESCO procurement, (2) choosing the right service classification for your load profile, (3) reducing therm volume, and (4) for the largest customers, managing maximum daily quantity on transportation rates.
ESCO supply procurement
For: All commercial and industrial gas customers
Shop the competitive gas commodity from licensed ESCOs (fixed or indexed) against the utility default supply to lock in or hedge winter pricing. Delivery stays with National Grid.
Service classification optimization
For: Commercial and industrial customers with significant volume
Match the rate class to your load profile — e.g., high-load-factor users may save on SC 4A's low per-therm rate, and large transportation users should evaluate SC 21 tiers and SC 22 interruptible service.
Maximum daily quantity (MPDQ) management
For: SC 21 large transportation customers
On SC 21 Rate 3, the demand charge is set per therm of maximum daily quantity, so smoothing peak daily gas demand reduces the demand component.
Volume reduction & efficiency
For: All customers, especially heating-dominated loads
Cut total therms through boiler/heating efficiency, controls, and building envelope improvements; lower volume reduces both delivery and supply cost.
Interval data analytics via EPO / Green Button
For: Commercial/industrial customers with interval meters
Use Energy Profiler Online load shapes or Green Button Connect feeds to identify usage patterns, verify rate fit, and target efficiency measures.
To implement these strategies, you need your 15-minute interval data. Learn how to download The Brooklyn Union Gas Company d/b/a National Grid NY interval data →
