Associated Electric Cooperative Inc.

The threat model here isn't abstract. Associated Electric Cooperative Inc. (AECI) operates the generation and transmission backbone delivering power to more than 2.1 million end-consumers across Missouri, Oklahoma, and Iowa, coordinated through 51 local cooperative systems. The attack surface is industrial: power generation facilities, high-voltage transmission networks, and the operational technology (OT) that ties them together. Founded in 1961 as a member-owned, not-for-profit wholesale cooperative, AECI's mandate is uptime and reliability for the six regional and six founding generation and transmission cooperatives it serves. A cybersecurity role at this scale means working at the intersection of IT and OT - securing SCADA systems, industrial control networks, and the enterprise infrastructure that supports a workforce of over 700. The cooperative structure means accountability flows to member-owners, not shareholders, which shapes risk tolerance and investment priorities differently than an investor-owned utility. AECI's operational footprint spans generation assets and transmission corridors, so the team must account for both legacy control-system environments and modern network architectures. The organization commits to infrastructure investment, workforce development, and environmental stewardship as core operating principles. For security practitioners, that translates to a mandate embedded in the physical grid - defending systems where a breach has kinetic consequences, within a governance model designed for resilience over quarterly returns.
