NIST SP 800-53 Rev.5 Controls Mapping for DER Aggregators (Guide)

DER aggregators act as intermediaries between distributed energy assets (e.g., solar PV, batteries, EV chargers) and wholesale markets or utility systems, requiring robust cybersecurity to protect against data integrity violations, unauthorized control actions, and cascading grid impacts. This guide interprets and tailors NIST SP 800-53 Rev. 5 — a foundational catalog of security and privacy controls for U.S. federal information systems — to address the hybrid IT/OT nature of DER aggregation, where cloud-based orchestration platforms interact with edge devices via protocols like IEEE 1547, OpenADR, and IEEE 2030.5. It emphasizes control applicability based on the aggregator’s role (e.g., third-party vs. utility-owned), deployment model (cloud-hosted, co-located, or edge-distributed), and data sensitivity (e.g., real-time metering, dispatch commands, customer PII). The mapping includes implementation guidance, compensating control considerations, and rationale for control selection—particularly for high-impact families like System and Communications Protection (SC), Incident Response (IR), and Supply Chain Risk Management (SR). Additionally, it integrates with NISTIR 8294 (Cybersecurity Framework for DER) and supports alignment with FERC Order No. 2222 and NAESB standards for interoperable, auditable, and resilient aggregation operations.
