A top-10 North American electrical utility

Planned hybrid-cloud migration for legacy SCADA-adjacent applications as part of a distribution-management uplift program.

Challenge

A distribution-management modernization (MSCR) forced dozens of aging integrations — some tied to SCADA, dispatch and regulatory reporting — to absorb new functionality under an aggressive regulatory timeline, with zero tolerance for grid-operation disruption.

Approach

• Identified stakeholders and documented current-state of environments and legacy applications.
• Defined a migration strategy balancing urgent requirements, risk, interdependencies and budget ceilings.
• Designed transition hybrid architectures aligned with the progressive on-site decommissioning plan.
• Designed target cloud architectures combining Azure analytics (Databricks) and AWS application (Lambda, SQS, SNS) workloads.
• Produced system-integration architectures across SAP, Talend, Gen4/OSI SCADA, Monarch and intranet dispatch.

Outcome

A sequenced, risk-managed plan accepted by the program and funded. The hybrid pattern let the utility meet regulatory deadlines while sparing teams from a big-bang migration.

Technology stack

SOA, EDA, microservices, REST, AWS Lambda/SQS/SNS, SAP, Talend, Azure Databricks, Azure AD, Oracle, Gen4 & OSI SCADA integrations

Estimated return on investment

Estimates are directional, based on comparable modernization benchmarks. Actual savings depend on starting baseline, scope and execution discipline.
