Rate Recommendations by Use Case
Mid-size commercial facility
A facility using 20,000-80,000 therms/year falls in GSG. Pay NJNG tiered delivery plus commodity, and shop suppliers against the $0.4567/therm BGSS Price to Compare.
Commodity is a large share of the bill and is competitive, so benchmarking against BGSS is the fastest savings lever.
- Pull 12 months of therms from My Account usage analysis
- Solicit fixed-rate supplier quotes vs. $0.4567/therm
- Confirm your GSG class assignment in the BPU No. 12 tariff
Large industrial / large-volume customer
A 100,000+ therm/year customer qualifies for GSG-LV and can elect firm transportation — buying gas from a marketer and paying NJNG only delivery and balancing.
At this scale, self-supplying commodity via firm transportation typically beats bundled BGSS sales, despite added balancing duties.
- Model firm transportation delivery + balancing vs. BGSS sales
- Set up EBB access for nominations and daily burn data
- Hold clear title to delivered gas per tariff eligibility
Energy/data team automating data capture
With no public API or Green Button, automate via supplier EDI 867 and the EBB if licensed, or use Nectar's API with customer permission; commercial buildings can pull EnergyCAP data.
EDI/EBB are the structured supplier feeds; Nectar and EnergyCAP cover customer-permissioned and benchmarking use cases.
- Use Nectar for fast customer-permissioned access (no NJNG agreement) — docs.nectarclimate.com
- Pursue EDI/EBB only if you hold a BPU supplier license
- Register buildings >25,000 sq ft with EnergyCAP

Cost Optimization Strategies
Because supply is competitive, C&I customers can lower delivered cost by comparing third-party supplier offers against the BGSS Price to Compare and, at scale, electing firm transportation to self-supply commodity. Right-sizing the General Service class and managing AMR/usage data also helps.
Shop commodity against BGSS
For: All sales customers (RS, GSS, GSG)
Compare licensed third-party supplier quotes to the $0.4567/therm BGSS Price to Compare; switch if a supplier beats it.
Elect GSG-LV firm transportation
For: C&I ≥ 100,000 therms/year
Large-volume customers (100,000+ therms) can take firm transportation and buy gas directly from a marketer, paying NJNG only delivery and balancing.
Verify correct General Service class
For: All C&I
Confirm GSG vs GSS vs GSG-LV assignment matches annual therms to capture the lowest applicable delivery determinants.
Use EnergyCAP benchmarking
For: Commercial buildings >25,000 sq ft
Commercial buildings >25,000 sq ft get NJNG billing data pushed to EnergyCAP — use it to find efficiency opportunities and meet NJ benchmarking mandates.

Frequently Asked Questions
Does NJNG support Green Button or a public API?▾
No. NJNG does not offer Green Button Download/Connect My Data or a public developer API. Structured access is via EDI (ANSI X.12 4010) and the Electronic Bulletin Board for licensed suppliers, or via Nectar's API with customer permission (see docs.nectarclimate.com). Proposed NJ BPU AMI rules (Docket EX24090717) may change this in future years.
Can a C&I customer get interval gas data?▾
Not sub-daily. NJNG uses AMR for daily meter reads and has not deployed 15/30-minute interval metering for gas. Customers see usage analysis in My Account; licensed suppliers retrieve monthly/historical usage via EDI 867 and daily burn data through the EBB.
How does a third party access our usage data?▾
Two paths: (1) a BPU-licensed supplier signs an NJNG supplier agreement and pulls data via EDI 867 or the EBB (NJNG assumes the supplier has customer authorization); or (2) a consultant uses Nectar's API with the customer's permission — no separate NJNG agreement needed (see docs.nectarclimate.com). Commercial buildings >25,000 sq ft also flow data to EnergyCAP.
What is the current BGSS price and how does it relate to C&I rates?▾
The BGSS Price to Compare for residential and General Service Small sales customers is a verified $0.4567/therm (December 2025 through the 2026 forecast period, NJ BPU Docket GR25050318). It is the commodity benchmark; C&I delivery charges are tiered by General Service class (GSG / Large Volume GSG-LV) and specified in the BPU No. 12 tariff.
Should a large C&I customer take firm transportation?▾
Often yes at 100,000+ therms/year (GSG-LV). Firm transportation lets you buy gas from a licensed marketer and pay NJNG only delivery and balancing, avoiding the utility commodity margin. You must hold clear title to delivered gas and manage daily nominations/balancing via the EBB, so model both options first.
