With high DER penetration, Utilities are mandating telemetry for larger DER’s to be connected to Utility DERMS or SCADA/ADMS. A good example is the Electric Rule 21 interconnection by the California Public Utilities Commission mandates the interconnection standards for a select set of renewable generators. These interconnection requirements would require Inverters to support IEEE 2030.5 or DNP3 and need to connect to Utility SCADA Systems directly or through an Aggregator initially for monitoring purposes and later for control as well. The requirements also mandate compliance with cybersecurity requirements as specified by the utility or as per SIWG and CSIP in California.
