The Rising Shield: Cybersecurity Takes Center Stage in the Solar Revolution
The rapid expansion of distributed energy resources (DERs) – solar, battery storage, microgrids, and more – is fundamentally reshaping the power grid. But this exciting evolution isn’t without its challenges. As more devices connect to the grid, the potential for cyberattacks increases, demanding a proactive and robust cybersecurity approach. Legacy devices, not originally designed with today’s threats in mind, are particularly vulnerable.
A New Baseline for Security: UL Solutions Steps Forward
Recognizing this growing necessitate, UL Solutions has launched a new certification program establishing the first industry-wide cybersecurity baseline for DERs and inverter-based devices. This isn’t just about protecting individual systems; it’s about safeguarding the entire grid. The program provides a consensus-based framework for manufacturers, utilities, regulators, and grid operators to mitigate cyber risks.
Beyond Safety: Integrating Cybersecurity into Design
Traditionally, safety testing has been paramount in the solar industry. Now, cybersecurity is being integrated as an equally critical component. UL Solutions’ new program complements existing safety standards, like UL 1741, rather than replacing them, offering manufacturers flexibility in meeting required protections. This holistic approach ensures that security is embedded from the start, rather than being an afterthought.
The Importance of Standards: UL 2941 and Beyond
The certification program is built upon UL 2941, the “Standard for Cybersecurity of Distributed Energy and Inverter-Based Resources.” This standard outlines specific cybersecurity requirements for networked, software-driven devices that manage energy flow and impact grid stability. It covers both technical controls – like access management and cryptography – and policy areas, including data handling and documentation.
From Research to Reality: The Evolution of the Standard
The development of this standard wasn’t a sudden leap. It evolved from extensive fieldwork, including test cases conducted by the U.S. Department of Energy’s National Laboratory of the Rockies (NLR) in 2019. These early tests highlighted the need for a dedicated cybersecurity standard that could accommodate the diverse range of DER technologies and their complex ownership structures. The NLR’s research focused on critical areas like authentication, authorization, confidentiality, and data integrity for microgrid communications.
The Future of Grid Security: A Collaborative Effort
The need for robust cybersecurity isn’t limited to standards and certifications. It requires ongoing collaboration between industry stakeholders. As Danish Saleem, a senior researcher at NLR’s Cybersecurity Research Center, emphasizes, “As energy resources integrate with the grid, cybersecurity can no longer be an afterthought and must be built into device design and deployment.”
What Does This Mean for Homeowners and Businesses?
Increased cybersecurity in DERs translates to greater reliability and peace of mind. Protecting these systems from cyberattacks ensures a stable energy supply and safeguards sensitive data. While the technical details are complex, the benefits are clear: a more secure and resilient energy future.
Pro Tip:
When choosing a solar installer or DER provider, inquire about their cybersecurity practices and whether their products are certified to industry standards like UL 2941.
FAQ: Cybersecurity and Distributed Energy Resources
- What are DERs? Distributed Energy Resources are smaller-scale power generation sources located closer to the point of consumption, such as solar panels and battery storage systems.
- Why are DERs vulnerable to cyberattacks? Many DERs rely on software and network connectivity, creating potential entry points for malicious actors.
- What is UL 2941? It’s a standard that sets cybersecurity requirements for DERs and inverter-based resources.
- How does cybersecurity certification benefit consumers? It provides assurance that DERs are protected against cyber threats, ensuring a more reliable energy supply.
