Third-Party API Access

MTNGUD publishes no public REST, GraphQL, or SOAP API and operates no developer portal. The UtilityNexus portal's internal APIs are not externally accessible. Nectar provides API access to this utility's billing data — see docs.nectarclimate.com. For direct utility access, third parties must use manual, case-by-case data requests with written customer authorization, or negotiate a custom arrangement with the utility — a process that can take weeks to months with no guarantee of success.

Program
None (manual requests only)
Auth Method
Written customer authorization submitted with each manual request

EDI (Electronic Data Interchange)

MTNGUD does not offer EDI for customer data access — no implementation guides, trading partner enrollment, VAN or direct connection specifications, and no support for 814, 820, 867, 810, 824, or 503 transaction sets. Business customers needing structured data should download statements from the portal or request bulk data through customer service; custom integrations would require individual negotiation via the Engineering Department at (615) 597-4300.

Middle Tennessee Natural Gas Utility District (MTNGUD) Data Access FAQ

How do commercial customers access MTNGUD billing and usage data?

Enroll the account in the UtilityNexus portal at https://mtng.utilitynexus.com to view current and historical statements and graphical monthly usage. For data exports beyond the portal, request manual exports through customer service at (833) 438-6864, or engage the Engineering Department at (615) 597-4300 for large C&I accounts.

Does MTNGUD provide interval (hourly or 15-minute) gas data?

No. MTNGUD has not deployed AMI; traditional dial meters are read monthly per Tennessee Regulatory Authority rules. Energy analysis must be based on monthly consumption totals — plan demand-side projects accordingly, since no interval granularity exists.

Can a consultant or energy manager pull a client's MTNGUD data?

Only manually. Obtain written customer authorization specifically granting release of billing and usage data, then contact MTNG at (833) 438-6864 with the customer's account number, service address, your business details, and the requested data and date range. Expect 5-10 business day turnaround per request; there is no API, EDI, or automated channel.

Does MTNGUD support Green Button, EDI, or an API?

No to all three. There is no Green Button DMD/CMD, no EDI trading partner program (814/820/867/810 unsupported), and no public API or developer portal. The portal runs on CSA's UtilityNexus platform, whose internal APIs are not externally accessible.

What options do large industrial customers have for custom data?

Request a dedicated account manager through the Engineering Department at (615) 597-4300. MTNGUD may provide customized billing analysis, historical data reports, usage trend analysis, and rate consulting for large C&I accounts, and may negotiate custom data-sharing arrangements case by case.

Where are MTNGUD's gas rates published?
