Registered third parties sign a Data Security Agreement, start in sandbox mode against test accounts, then move to live mode to request customer-authorized billing and interval data via REST API, dashboard, or Green Button OAuth flows. A separate NY System Data Portal offers grid-infrastructure (non-customer) data via REST/ArcGIS.

KEDNY gas bills split a regulated delivery charge from a competitive (or default) supply charge. Delivery uses a declining-block design: commercial and industrial classes pay a fixed minimum charge for the first block of therms, then per-therm charges that decline with volume and differ by season (winter higher than summer for transportation classes). High-load-factor and large-transportation classes (SC 4A, SC 21) carry large fixed first-block charges that reward steady, high-volume consumption; SC 21 Rate 3 adds a demand charge per therm of maximum daily quantity. Verified figures (e.g., SC 3 ~$39.51 first-3-therm, SC 4A ~$250 first-10-therm, SC 21 Rate 3 ~$771.69 first-10-therm and ~$4,927.82/therm MPDQ demand) come from the publicly posted KEDNY rate summary; the current effective per-therm sheet is the KEDNY Gas Delivery Charges tariff (effective December 1, 2025).

For a deeper analysis including cost optimization strategies and historical rate trends:

• ⚠Energy Profiler Online requires a $600/year subscription and is limited to accounts with interval meters.
• ⚠EPO interval data is not billing-quality and may contain gaps — do not use it for billing disputes.
• ⚠Green Button Connect is in beta; third parties must sign a Data Security Agreement and pass sandbox testing before live access.
• ⚠Direct EDI access is for ESCOs/marketers and large transportation customers, not individual gas customers.
• ⚠AMI gas-module and Customer Energy Management Portal rollout is still in progress, so 15-30 minute AMI data is not available to all premises yet.
• ⚠Portal billing/usage history is limited to 24 months.
