New York State Electric & Gas Corporation (NYSEG) Rate Selection Guide
New York State Electric & Gas (NYSEG), an Avangrid utility, serves more than 920,000 electric customers plus natural gas across upstate and central New York. For commercial and industrial accounts, NYSEG offers interval data through Green Button Connect (ESPI/OAuth 2.0), mature ANSI X12 EDI for ESCO and supplier transactions, and a fully deregulated supply market where C&I customers can shop ESCOs for the energy-supply portion of their bill.
New York State Electric & Gas Corporation (NYSEG) Rate Schedule Comparison

| ESCO Supply | commercial | Market/contract supply price (separate from NYSEG delivery) | C&I customers hedging or optimizing the supply component |
Market Overview
New York is a retail-choice (deregulated) state. NYSEG is the regulated delivery utility whose T&D rates are set by the NY PSC, while energy supply is competitive. C&I customers may take default utility supply or contract with an ESCO for the supply component. ESCO enrollment and data exchange operate over ANSI X12 EDI under PSC Case 98-M-0667.

Community Choice Aggregation (CCA) Options
Municipalities in NYSEG territory may form a CCA to procure supply on behalf of residents and small businesses; larger C&I accounts typically contract directly with an ESCO.
Current Rate Schedules
NYSEG C&I delivery rates are set by the NY PSC under tariff PSC No. 120 and are billed separately from energy supply (which can come from NYSEG default supply or a chosen ESCO). Commercial accounts generally fall under SC-3 (general service) and large/demand-metered accounts under SC-7 (large general service, time-of-use). Verified delivery figures below are from the NYSEG Electricity Rates Summary effective May 1, 2025; a larger multi-year rate case is pending before the PSC, with a temporary ~0.2% electric delivery increase effective June 1, 2026 while the Commission completes review.

Rate Recommendations by Use Case
Large industrial / 500 kW+ facility
High-demand facilities reclassified to SC-7 should focus on demand management and voltage-level optimization.
The per-kW demand charge ($8.53-$14.14/kW) dominates the delivery bill, and primary-voltage service cuts that rate substantially.
- Pull 15-min interval data via Green Button Connect to find peaks
- Evaluate primary-voltage service to access the $8.53/kW rate
- Consider on-site generation/storage to shave coincident peaks
Mid-size commercial business
General commercial accounts on SC-3 should monitor demand to avoid SC-7 reclassification surprises and shop supply.
SC-3 covers most commercial load, but reaching 500 kW in two months triggers SC-7 reclassification with demand charges.
- Track demand against the 500 kW SC-7 threshold
- Use Energy Manager to spot rising peaks early
- Compare ESCO supply offers to default utility supply
Multi-site portfolio / energy manager
Portfolios spanning NYSEG and other NY utilities should standardize on Green Button Connect for automated interval data.
Green Button Connect's ESPI/OAuth API enables consistent, authorized data feeds across accounts for benchmarking and demand analytics.
- Register once with NYSEG and sign the DSA
- Use OAuth authorizations per account in My Account
- Centralize interval data for portfolio-wide peak analysis
Historical Rate Trends
NYSEG delivery rates are set through multi-year rate plans approved by the NY PSC. Recent years have seen phased delivery increases funding storm hardening, vegetation management, gas-pipe replacement, and the AMI smart-meter rollout.

Next expected change: A temporary ~0.2% electric delivery increase took effect June 1, 2026 while the PSC reviews NYSEG's pending multi-year rate case (originally requesting ~35% over three years).
Cost Optimization Strategies
For NYSEG C&I accounts, the biggest savings levers are managing billed demand (kW), optimizing voltage-level service, and competitive supply procurement. Because delivery and supply are unbundled, customers can attack both components independently.
Peak Demand Management
For: SC-3 demand-metered and SC-7 accounts
Use interval data (Green Button Connect) to identify and shave demand peaks that drive the per-kW SC-7 demand charge.
Voltage-Level Optimization
For: Large C&I accounts able to own/operate primary equipment
Where feasible, take service at primary or higher voltage to qualify for the lower SC-7 demand rate.
Competitive Supply Procurement
For: All C&I accounts in deregulated NY market
Shop ESCOs for the energy-supply component to hedge price volatility or lock fixed pricing, while NYSEG delivery stays regulated.
Time-of-Use Load Shifting
For: SC-7 time-of-use accounts
Shift flexible load to off-peak periods to reduce TOU energy delivery charges under SC-7.

Deregulated Market Shopping
New York's retail-choice market lets NYSEG C&I customers buy energy supply from a competing ESCO while NYSEG continues to provide regulated delivery. Supply choice can fix or hedge the volatile energy component, but contract terms, fees, and exit clauses vary widely among ESCOs.

Frequently Asked Questions
How can a C&I customer give an energy consultant ongoing access to NYSEG interval data?▾
The most scalable method is Green Button Connect: the customer logs into My Account, opens the Authorizations/Connected Apps section, and grants OAuth consent to an approved provider. The provider must first be registered with NYSEG and have a signed Data Security Agreement. For monthly billing-only data, a signed Customer Data Authorization Form is also accepted.
Can I pull 15-minute interval data over EDI?▾
No. NYSEG does not support direct 15-minute interval data requests via 814 or 867 EDI transactions (confirmed since the January 2020 update). EDI is used for enrollment, monthly usage, and billing; for interval data, use Green Button Connect instead.
What interval granularity is available for commercial accounts?▾
Commercial AMI accounts can obtain 5-minute interval data; standard AMI and legacy interval meters provide 15-minute electric data. Gas AMI meters report hourly. Up to 24+ months of history is available through Green Button Connect.
Does NYSEG offer competitive supply for business customers?▾
Yes. New York is a deregulated market, so C&I customers can buy the energy-supply portion of their bill from a competing ESCO while NYSEG continues to provide regulated delivery. Supply choice can hedge price volatility, but contract terms vary, so review pricing and exit clauses carefully.
How long does it take to become an EDI trading partner with NYSEG?▾
Plan for several weeks: creditworthiness and NYISO approval take 2-3 weeks, Phase I EDI testing up to 3 weeks, plus optional Phase III and UBR testing. A signed Data Security Agreement is required before production access.
