SunSpec Ecosystem Newsletter March 2022

Dear Colleagues,

For several years, the SunSpec Alliance has been examining the cybersecurity posture of Distributed Energy Resources (DERs) and calculating when an investment in robust, standardized cybersecurity capabilities might help institute DERs as a foundational element of the world’s energy infrastructure. That time is now.

As seen in the Russian attack on Ukraine, large power generation systems have proven to be easy to compromise given their large, conspicuous, and stationary nature—despite elaborate security protections. Take one of these energy generators down and hundreds of thousands of homes go dark for a long time. In contrast, replace a single large power generator with a fleet of small DERs of an equivalent aggregate capacity (say 100,000 – 200,000 systems), and you have a power generation system that requires no fuel, is more difficult to locate in its entirety and is harder to attack. Connect these systems to each other with the Internet; secure them in a thorough and cost-efficient way; integrate electric vehicles to provide auxiliary energy storage; and you have a resilient and flexible power system that can withstand major assaults—from war or weather—and remain (at least partly) operational. In this scenario, cybersecurity is the lynchpin.

In 2022, SunSpec will be leading the effort to establish DER as the energy generation source that delivers the lowest total cost, highest availability, highest resilience, and the most cost-effective cybersecurity in the energy industry. To this end, we will continue to educate our members by presenting cutting-edge cybersecurity research in webinars like the one coming up on March 24th and we will be establishing SunSpec Cybersecurity Certified™ program for DER devices (more coming in April 2022). If you are interested to work with us on this program, or if you would like to compare ideas with us, please contact

Kind Regards, 

Tom Tansy

SunSpec & Sandia DER Cybersecurity Webinar:

Cryptographic, Protected Processors for DER Authentication, Control, easurement, and Attestation

This briefing by the The Trusted Computing Group's (TCG) Measurement and Attestation RootS (MARS) Work Group will introduce Measurement and Attestation (M&A) concepts, relevant use cases and a simplified MARS architecture. Attendees will understand the need for M&A and that it can be enabled by microcontroller manufacturers with little overhead. That is especially true for those already including cryptographic accelerators, as is commonplace.

Speaker: Tom Broström, Chair of the MARS Work Group in the Trusted Computing Group (TCG)

Date: March 24, 2022 at 9 a.m. - 10 a.m. Pacific

Gain access to valuable information by becoming a Member of the SunSpec Alliance and joining a SunSpec Work Group. The work groups listed below are currently active and meeting to address the following objectives:
At the end of 2021, the SunSpec (Modbus) Device Interface work group completed development of the SunSpec information models required by DER devices for IEEE 1547-2018 compliance ("700 series") and refined the battery energy storage models ("800 series") to better support multiple chemistry types and complex system configurations. The group is now working on a RESTful Web Services interface for devices that can be used as an alternative to the traditional Modbus interface.
The IEEE 2030.5 / SAE J3072 EV Charging Profile Work Group has just published the first draft of the IEEE 2030.5 V2G AC Profile for public comment. This work group will be reconvening in March of 2022 to review comments and update the draft. 
The SunSpec & Sandia DER Cybersecurity Work Group has a full slate of monthly webinars on all aspects of DER security and has convened a sub-group to define requirements for an open source security-readiness assessment tool.
The SunSpec IEEE 2030.5 Conformance Profiles Work Group is now meeting to update the testing procedures for all profiles. 
The SunSpec Rapid Shutdown Work Group is refining test procedures and working on a collaborative marketing program to spread the word about open standards.
The Orange Button Work Group is now an open source community that lives on GitHub/Slack and meets every Tuesday at 11 AM Pacific. We are building an open product registry that gives details on every inverter, solar PV module, and battery storage device in the market. Contact to participate.
