Rate Recommendations by Use Case
Commercial building (offices/retail)
Most commercial buildings take service on Rate Schedule GSG, paying the regulated delivery charge plus either SJG BGSS or a shopped commodity price.
GSG is the default C&I class. With delivery fixed at $1.106610/therm (June 2026), the lever is the commodity price and total therms.
- Shop the commodity portion against SJG's BGSS price to compare.
- Benchmark via EnergyCAP if over 25,000 sq ft.
- Capture SaveEnergy efficiency rebates.
Large industrial / high-volume site
Facilities using 100,000+ therms per year should evaluate GSG-LV and firm transportation service with a competitive supplier.
Large-volume classes can reduce per-therm delivery cost, and firm transportation lets you buy commodity competitively while SJG delivers.
- Confirm GSG-LV eligibility against annual therms.
- Negotiate fixed commodity terms for budget certainty.
- Manage daily nominations carefully to avoid imbalance charges.
Energy consultant / aggregator
Consultants serving multiple SJG accounts should register with NJBPU and SJG to pull usage via EDI and EnergyCAP.
Documented authorization plus EDI 867HI/867MU and EnergyCAP gives standardized multi-account data for analysis and procurement.
- Complete NJBPU and SJG Energy Consultant registration.
- Keep customer authorizations on file.
- Use EnergyCAP/Portfolio Manager for benchmarking.
Third-party gas supplier
Suppliers entering SJG territory must complete NJBPU licensing and SJG EDI certification before enrolling customers.
EDI 814 enrollment, 867 usage, and Marketer Portal nominations are the operational backbone of serving C&I gas customers in NJ.
- Budget for ESG testing fees and collateral.
- Plan a 10-12 week certification timeline.
- Decide UCB vs. dual billing and whether to use POR.

Cost Optimization Strategies
Because SJG's delivery charge is regulated and uniform, C&I savings come primarily from shopping the gas commodity, qualifying for the correct rate class, and managing consumption and nominations.
Shop the gas commodity
For: All C&I gas accounts
Buy the BGSS/commodity portion from a licensed NJ third-party supplier; SJG still delivers at the same regulated rate. Compare supplier offers against SJG's BGSS price to compare.
Confirm correct rate class
For: High-volume industrial sites
Verify whether your annualized usage qualifies for GSG-LV (100,000+ therms), which can lower per-therm delivery costs versus standard GSG.
Use EnergyCAP benchmarking
For: Commercial buildings over 25,000 sq ft
Track interval and monthly consumption across buildings via EnergyCAP/Portfolio Manager to target efficiency and load-shaping projects.
Capture efficiency rebates
For: C&I facilities upgrading gas equipment
Use the SJG SaveEnergy contractor programs (Direct Install, Prescriptive/Custom, Engineered Solutions) to offset equipment upgrades.

GSG covers most commercial and industrial accounts that do not qualify for another schedule. Customer charges and riders are defined in Tariff No. 14.
Can my business shop for a different gas supplier?▾

How does a third-party supplier get usage data for my account?▾
Licensed suppliers and registered energy consultants obtain data through SJG's EDI system. Monthly usage flows via EDI 867MU and up to 12 months of historical usage via 867HI, after the customer's authorization is documented. Suppliers must complete NJBPU licensing and SJG's EDI certification first.
Does South Jersey Gas offer interval data or Green Button?▾

What does EDI certification involve for a supplier?▾
Suppliers must hold an active NJBPU license, submit a full application package, execute SJG agreements, post collateral, and pass Level 1 (connectivity) and Level 2 (20+ business scenarios) certification with SJG's EDI provider (ESG). Plan for roughly a 10-12 week timeline plus testing fees.
What is the best way for a large facility to lower gas costs?▾
Confirm the correct rate class (GSG-LV applies at 100,000+ annualized therms), shop the commodity portion against SJG's BGSS price, benchmark consumption in EnergyCAP, and capture SaveEnergy efficiency rebates. Delivery charges are regulated and uniform, so savings come from commodity price and reduced therms.
