Journey to One Million Assets

Executive Summary

The need for scalable platforms has become critical as utilities face the rapid growth of distributed energy resources (DERs), requiring real-time control and data management. In response to this demand, Kitu Systems has successfully scaled its Citadel platform to manage over one million active DERs.

Key innovations include containerized deployment with Kubernetes, a migration to PostgreSQL for improved data performance, and a cost-effective, cloud-agnostic testing framework. Compliance with IEEE 2030.5 and CSIP/CSIP-AUS ensures interoperability and regulatory alignment, while advanced soak testing and negative test scenarios confirm platform resilience. Real-world deployments with Australian Distribution Network Service Providers (DNSPs) and aggregators validate Citadel’s readiness at scale.

Kitu recommends a forward-looking approach to DER management, prioritizing open standards, cloud flexibility, and scalable architecture to meet the evolving demands of the modern grid.
