California Rule 21 Solutions

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 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 to cyber security requirements as specified by the SIWG and in the CSIP.

ASE has combined its over 35 years of expertise in working with utilities and OEM’s to design a secure and cost effective solution to meet these interconnection standards. Further ASE has partnered with its parent company Kalkitech and its Energy IoT Division to provide a comprehensive solution for Rule 21 that addresses the data collection, protocol and security at the Edge as well as data collection and integration at the Utility or Aggregator level as well.

Our IEEE 2030.5 Aggregator Client, KALKI.IO Device Management & Head End and Intel ODM Partnerships enable Inverter manufacturers, Utilities, Developers and System Integrators a comprehensive set of tools, software and hardware to be compliant and lead the pack in CA Rule 21 projects.

Rule 21 implementation will result in a large number of small solar generators getting connected to the Utility Grid and communicating to the utility directly or through an Integrator. It is humanly impossible to manage, maintain and keep up to date these systems. Further cyber security audit and analysis of these systems also need to be done routinely.

Our Device Access Pack provides remote configuration and management access for field devices by securely extending the connectivity between device’s programming port and engineering tool over a public/private network.
