Proposal information to include, objective, methods, results, and conclusion: Rule 21 Low Cost Telemetry mandate from California Public Utilities Commission (CPUC) requires all Distributed Energy Resources (DER) above 1 MW to provide telemetry data to the Utility SCADA systems over IEEE 2030.5, a IEEE 1547-2008 protocol. The different phases of the said mandate requires initially to implement telemetry and later expand to control and data aggregation. This paper and presentation addresses the requirements, the deployment architecture, implementation and inter-operability challenges, security expectations and lessons learned. This paper also discusses some of the mandatory design considerations for building a cost-effective telemetry gateway solution with extensive security, monitoring and remote management capabilities. Paper also covers practical integration and operational issues identified and how these are resolved effectively based on the on-field experiences
ASE worked over a couple of years to adapt their Edge Gateway to comply with the Rule 21 requirements and the IOU security and remote management requirements. We cover our experience with this exercise, including design, architecture, security, integration and inter-operability issues.
ASE is currently approved by one of the IOU’s and working with other IOU’s and have successful deployments complying with the Rule 21 Low Cost Telemetry requirement and IEEE 2030.5 Protocol. ASE also has launched the DER Aggregator solution for Low Cost Telemetry which further reduces cost and improves security for the Utilities.
This paper details the journey and lessons learned integrating DER’s to Utility SCADA systems for Low Cost Telemetry complying with CA Rule 21 requirements and IEEE 2030.5 Protocol.
