TX Electric Cooperatives:
OT/IT Convergence Target

Brazos Electric Power Cooperative filed for $2.1 billion Chapter 11 bankruptcy after Winter Storm Uri. DMEA in Colorado suffered a cyberattack that took billing offline for over a month with ICS devices bricked. NERC CIP-003-9 enforcement began April 2026 — extending vendor MFA and supply chain risk requirements to virtually every TX distribution co-op for the first time. CoreRecon documents the full attack surface, compliance cliff, and controls that matter for Texas electric cooperatives.

What This Brief Covers

TX Electric Cooperative
Cyber Threat Brief

Full intelligence report on the attack surface facing Texas electric cooperatives — from the Brazos Electric $2.1B bankruptcy and DMEA cyberattack, to NERC CIP-003-9 enforcement, OT/IT convergence risk, and the ERCOT QSE cyber-financial boundary. 62 verified sources. No marketing fluff. Documented incidents, applicable regulations, and actionable controls built for co-op GMs, IT directors, and operations managers.

62 Verified Sources Including:

  • Brazos Electric — $2.1B Chapter 11, Uri bills, 16 member distribution co-ops, HILCO $121M securitization obligations
  • DMEA Colorado (Nov 2025) — billing offline 1+ month, ICS devices bricked, Russia-linked intrusion, 34,000 meters
  • Colonial Pipeline — VPN credential compromise, 6-day shutdown, OT shut down to prevent IT-to-OT spread
  • NERC CIP-003-9 (eff. April 1, 2026) — vendor MFA, supply chain management, now applies to Low Impact BES Cyber Systems
  • ERCOT market participation: QSE interface, ICCP telemetry, simultaneous physical and financial compromise scenario
  • OT attack surface: DNP3, Modbus, IEC 61850 — no native authentication, passive monitoring required
  • AMI smart meter exposure: 10,000 inverters = 50MW grid-significant but below NERC CIP threshold gap
  • Dragos Community Defense Program — free for <$100M co-ops but platform, not managed service; Accenture acquisition June 2026
  • NERC penalties up to $1M/violation/day | CIP-015 compliance deadline 2028–2030 | RUS loan cybersecurity conditions
  • 8 co-op-specific controls with 30/60/90 implementation roadmap
