SunSpec Cybersecurity Certification Work Group

Every year the U.S. commissions 1 million new DER systems, bringing us closer to a more resilient and decentralized power grid. However, the security profile of DERs remains ambiguous and could limit the usability of installed devices. Meanwhile, conflicts in Europe have increased the threat level for critical infrastructure and the power grid.

To enable DERs to reach their full potential and address growing threats, SunSpec is forming the Cybersecurity Certification Work Group to create a cybersecurity certification option for products receiving IEEE 2030.5 certification. To help make the program a reality, SunSpec is partnering with Lumian Foundation, a new consortium spun out of the SunSpec Blockchain Work Group.
