ERCOT Tech Stack

Independent system operator managing Texas's electric grid for 27 million customers

Utilities Taylor, TX 501–1,000 employees Nonprofit

ERCOT operates the transmission backbone for 90% of Texas's electricity supply—54,100+ miles of lines serving 27 million customers and balancing 1,250+ generation units in real time. The tech stack reveals a hybrid modernization in motion: legacy domains (PowerWorld, Oracle, C#, Java) sit alongside cloud infrastructure (Azure, Kubernetes, OpenShift, Terraform, Ansible) and streaming systems (Kafka, ActiveMQ, Splunk). Engineering-heavy hiring (39 of 79 roles) with strong senior representation suggests active rebuilds in grid software and market operations systems—aligned with pain points around legacy modernization and real-time operational stability.
