Project Information

CPS Energy — Company Overview

CPS Energy is the nation’s largest community-owned electric and natural gas utility, serving more than ~970,000 electric and ~390,000 natural-gas customers in San Antonio and portions of seven adjoining counties. Founded in 1860 and owned by the City of San Antonio since 1942, the utility provides reliable, competitively priced service and contributes a portion of gross revenues to support city services.

SCADA Upgrade at CPS Energy — Project Description & Business Drivers

  • Reliability & situational awareness: Replace/modernize aging SCADA platforms to improve visualization, alarm handling, and operator decision support for both gas and electric operations.

  • Cybersecurity & compliance: Incorporate modern cybersecurity controls and architecture patterns aligned to current standards for operational technology (OT), especially for EMS/SCADA environments.

  • Integration & data fidelity: Enable tighter integration with enterprise historians (e.g., PI), GIS, OMS/DMS and related systems using open architectures and a single, authoritative network model.

  • Lifecycle continuity: Address end-of-life software/hardware and establish synchronized disaster recovery and operator training capabilities.

Scope of Project

CPS Energy’s modernization effort spans both gas SCADA and electric EMS/SCADA domains:

  1. Gas SCADA Modernization

    • HMI & visualization refresh with modern situational awareness displays, pipeline topology views, and dynamic coloring.

    • Advanced alarm management to reduce nuisance alarms and improve response to true abnormal conditions.

    • Operational analytics including inventory & linepack calculations to support capacity and contingency management.

    • System architecture & integrations: Open interfaces for PI historian and GIS, supporting enterprise reporting and field coordination.

    • Resilience & training: Synchronized disaster recovery and an Operator Training Simulator (OTS) for consistent operator proficiency.

    • Cybersecurity controls embedded in the platform design.

  2. Electric EMS/SCADA Replacement

    T&D system integration: Coordination with OMS/DMS software upgrades to maintain a coherent distribution network model and streamline outage and switching operations.

Key Functional Enhancements

  • Operator effectiveness: Consistent, high-fidelity one-line/topology views; contextual alarms; faster abnormal-situation recognition.

  • Model-driven operations: Single dynamic network model from GIS to DMS/OMS reduces duplication and errors.

  • Training & readiness: OTS enables scenario-based drills without impacting live operations.

  • Resilience: Built-in disaster recovery synchronization to shorten recovery time objectives.

  • Security posture: Modernized architecture with contemporary OT security controls.

Technology & Vendor Ecosystem 

CPS Energy’s gas SCADA using a contemporary, open architecture with integrations to PI and GIS. EMS/SCADA replacement is underway per Board materials. (CPS Energy and industry sources frequently reference advanced, vendor-neutral integrations; AspenTech OSI Monarch is a common platform in the sector, but specific CPS platform details for electric are not confirmed in public documents cited here.)

Implementation Approach

  1. Assessment & design: Inventory legacy points, networks, and displays; define alarm philosophy and cybersecurity requirements; map integrations (PI, GIS, OMS/DMS).

  2. Build & integrate: Stand-up parallel environments; configure SCADA databases, displays, alarm rationalization, historian tags, GIS model interfaces, and DR replication.

  3. Testing & cutover: Factory/Site Acceptance Tests, model validation, performance and failover tests, then phased cutover to minimize operational risk. (Operator training via OTS precedes go-live.)

  4. Stabilization & optimization: Post-go-live tuning of alarms, displays, and integrations; ongoing cybersecurity posture reviews.

Benefits & Outcomes

  • Improved reliability and faster response to abnormal conditions across gas and electric operations.

  • Data-driven operations via integrated historian/GIS and consistent network models—fewer manual reconciliations between OMS/DMS and SCADA.

  • Operator readiness & safety through simulator-based training and clearer situational awareness.

  • Future-ready architecture that supports incremental enhancements, DER/ADMS alignment, and continuing security updates
