On October 24, 2024, NASEO hosted a solar-cybersecurity workshop and exercise to socialize and validate the CATSS toolkit, expand the CATSS advisory group stakeholder network, and explore incident response and mitigation actions to enhance solar cybersecurity. The event engaged a number of new entities, including the Federal Bureau of Investigation (FBI), Solar Energy Industries Association (SEIA), the American Clean Power Association (ACP), and the U.S. Department of Energy’s Grid Deployment Office (GDO), all of which expressed interest in connecting with State Energy Offices. NASEO has released a suite of tools to support key stakeholders in enhancing solar-cybersecurity, including Cybersecurity Guidance for State Procurement of Solar Assets, Legislative Engagement Options for Solar Cybersecurity, Workforce Development Support Tools, and Solar Supply Chain Cybersecurity Vulnerability Assessments, and will continue to disseminate guidance and resources from the project. Additionally, NASEO will be exploring opportunities to engage State Energy Offices on cybersecurity considerations for the Grid Resilience and Innovation Program (GRIP), and Solar for All programs. For more information on how to get involved with CATSS, or to connect with the FBI, SEIA, ACP, or GDO on solar cybersecurity issues, contact Campbell Delahoyde (cdelahoyde@naseo.org) and Sarah Trent (strent@naseo.org).
