See the Mid-South Electric Cooperative Association Rate Schedules & Tariff Guide →Interval Data & Smart Meters
MidSouth has invested heavily in grid modernization — distribution fault anticipation sensors with Texas A&M since 2017 and a Virtual Peaker DERMS managing 600+ smart thermostats since 2024 — but no published interval/smart-meter download capability exists for retail customers. Interval data requests go through Member Services.

- 01Contact MidSouth Electric at (936) 825-5100 or memberservices@midsouthsynergy.com
- 02Request interval/smart-meter data download capability for your account
- 03Ask about format (PDF, CSV, XML) and granularity (15-min, 30-min, hourly)
- 04Inquire about Green Button enrollment if it becomes available
Interval data is essential for rate comparison and TOU analysis.

MidSouth advertises no public API, developer portal, or OAuth consent framework. Nectar provides API access to this utility's billing data — see docs.nectarclimate.com. Direct third-party access at the utility follows a customer consent model: written authorization submitted to Member Services, reviewed in 5-10 business days. Technology partnership inquiries route to the Commercial/Developers team with a 4-12 week evaluation period.

- 02Email memberservices@midsouthsynergy.com or call (936) 825-5100

EDI (Electronic Data Interchange)
No public retail EDI program is documented. MidSouth operates in two wholesale markets — ERCOT (using Texas Standard Electronic Transactions, TX SET) and MISO (standard EDI protocols) — but those are grid/wholesale communications, not retail customer channels. ANSI X12 would be the likely standard if EDI is supported, unconfirmed.

- 02Request EDI specifications and trading partner enrollment documentation

Mid-South Electric Cooperative Association Data Access FAQ
Can C&I customers get interval data from Mid-South Electric Cooperative?▾
Not through any self-service channel. AMI deployment is underway, but the portal exposes no interval download and granularity is unpublished. Contact Member Services at (936) 825-5100 or memberservices@midsouthsynergy.com, specify the granularity (15-min, 30-min, hourly) and format you need, and expect a manual process.
Does MidSouth support Green Button, APIs, or EDI for retail customers?▾
No. There's no Green Button DMD/CMD, no ESPI implementation, no public API or developer sandbox, and no documented retail EDI trading partner program. MidSouth's ERCOT TX SET and MISO EDI activity is wholesale-market only — not a retail customer data channel.
How does a consultant request data on behalf of a MidSouth member?▾
Via the customer consent model: get a written authorization letter naming your firm with account numbers and scope, submit it to memberservices@midsouthsynergy.com or (936) 825-5100, and specify data types, timeframe, frequency, and format. Expect acknowledgment in 2-3 business days and processing in 5-10.
Why does MidSouth operate in both ERCOT and MISO?▾
Its South Central Texas territory straddles the two wholesale markets — unusual for a cooperative. That dual position drove the 2024 Virtual Peaker DERMS deployment, which manages 600+ smart thermostats for demand response and wholesale cost management across both markets.
What billing data is available in the MidSouth portal?▾
Current bills, 12+ months of billing history, usage history, balances, and alerts at billing.midsouthsynergy.com/onlineportal, plus the MSEC mobile app with usage graphs. Bills save as PDF through the browser only — there's no CSV/XML bulk export.
