Current Rate Schedules

Indiana North C&I rates are governed by IURC Gas Tariff No. G-20 (base rates approved in Cause No. 45468, effective Nov. 18, 2021).

Specific per-therm dollar figures were not independently verified for this draft and should be read directly from the current G-20 tariff sheets and the latest GCA filing; rate structure is described qualitatively below.

Rate Recommendations by Use Case

🏪

Small/general commercial customer

Standard commercial customer on bundled sales service.

Recommended:
Rate 220 - General Sales Service

Rate 220 bundles delivery and gas supply with the quarterly GCA, the simplest option for general commercial loads that do not meet the 25,000 therm/yr transportation threshold.

Tips:
  • Track therms and GCA changes through My Account.
  • Add an authorized user for your energy consultant.
Est. monthly: Customer charge + distribution/therm + GCA (see G-20 tariff)
🏢

Larger commercial / mid-size facility

Higher-volume general-service customer.

Recommended:
Rate 240 - General Sales Service

Larger general-service sales customers fall under Rate 240; review whether annual volume approaches the 25,000 therm transportation threshold where Choice becomes available.

Tips:
  • Benchmark usage via the Energy Data Portal / ENERGY STAR if available.
  • Model transportation savings as volume grows.
Est. monthly: Customer charge + distribution/therm + GCA (~$0.37-$0.41 recent GCA)
🏭

Large industrial / transportation-eligible customer

Non-residential customer using >=25,000 therms/year that can buy its own gas.

Recommended:
Rate 245 - Large General TransportationRate 260 - Large Volume TransportationRate 270 - Long-Term Contract Service

Tips:
  • Compare quotes from approved suppliers (Constellation, Symmetry, CIMA, Kinetrex, NRG).
  • Use the Gas Tracking System for nominations, usage, and settlement.
  • Confirm consolidated vs. dual billing in the agency agreement.
