Rate Schedules & Tariff Analysis
VNG's C&I rate design splits the bill into a fixed monthly customer charge plus per-Ccf components. Sales-service schedules (2A/2B/2C) bundle a single billing rate that includes the gas commodity (Purchased Gas Cost). Delivery/transportation schedules (6, 7, 15) separate demand, capacity, delivery, and commodity charges — reflecting that the customer buys the commodity from a marketer under Virginia gas choice. Customer charges scale steeply with schedule size (from $26.54 on 2A to $1,207.29 on Schedule 7 and $3,774.26 on Schedule 15).

Virginia Natural Gas (VNG) Data Access FAQ
Does VNG offer interval (15-minute) data for C&I customers?▾
No. VNG uses Automated Meter Reading (AMR), not AMI, so only monthly usage is available (with aggregated daily views in Opower). There is no 15-minute or 30-minute interval data. For granular load analysis, plan around monthly consumption data.
What is the best way for a consultant to pull our usage data at scale?▾
For most customers, Green Button export from Opower (CSV/XML) under written authorization is the most practical method. Large C&I operations with trading partners can enroll in NAESB EDI and submit EDI 814 historical usage requests. VCDPA requests work for one-time pulls of all data on file.
Can our business choose a competitive gas supplier?▾
Yes. Virginia has retail natural gas choice. Eligible C&I customers can buy the gas commodity from a licensed supplier while VNG continues to deliver the gas, read the meter, and bill. Delivery (transportation) schedules such as Schedule 6 and Schedule 7 apply to customers taking supply from a marketer.
Which rate schedule applies to a commercial or industrial account?▾
It depends on usage and whether you take VNG sales service or third-party supply. General firm sales service uses Schedules 2A/2B/2C; large firm delivery (transportation) uses Schedule 6 (high load factor) or Schedule 7 (general firm delivery); large interruptible loads use Schedule 9; seasonal high-load uses Schedule 15. See the VNG tariff for the right fit.
How does EDI enrollment work for a C&I customer or ESCO?▾
Contact the VNG EDI team (edimsg@aglresources.com / 404.584.4495), execute a NAESB EDI Trading Partner Agreement, complete technical setup over VAN or AS2, pass UAT testing, then go live. Supported transactions include 814 (enrollment/usage), 810 (billing), 820 (payment), and 873 (commodity movement).
