S-4166-119
Read twice and referred to the Committee on Energy and Natural Resources.
Sponsored by Catherine Cortez Masto (D-NV)
What it does
This bill would amend the Energy Policy and Conservation Act to require states to address the physical security, cybersecurity, and resilience of local electricity distribution systems (those operating at 100 kilovolts or less) in their state energy security plans. It would also expand consultation requirements to include equipment suppliers, make federal technical assistance to states mandatory rather than optional, and require the Government Accountability Office to report to Congress by 2030 on how well state energy security plans are working. The bill's provisions would expire on September 30, 2031.
Who benefits
Residential and commercial electricity customers who depend on local distribution infrastructure. Rural and suburban communities whose power is delivered through lower-voltage local systems. State energy offices that would receive mandatory (rather than discretionary) federal technical assistance. Equipment suppliers for electricity generation, transmission, and distribution who gain a formal role in state planning consultations. Emergency management agencies that coordinate disaster response. Communities historically vulnerable to weather-related outages, such as those in hurricane or wildfire zones.
Who is hurt
Electric utilities that may face increased planning and compliance burdens to meet expanded state plan requirements. States with limited administrative capacity that must update their energy security plans to cover local distribution systems. Federal taxpayers who may bear costs of expanded mandatory technical assistance from the Department of Energy. Equipment manufacturers and suppliers who may face greater scrutiny of supply chain risks under the expanded planning framework. The bill's 2031 sunset could also disrupt long-term planning cycles for utilities and states that build multi-year programs around the requirements.
Supporters argue
Supporters argue that local distribution systems — the "last mile" of the grid serving homes and businesses — are the most vulnerable and least regulated segment of U.S. electricity infrastructure, yet are excluded from existing federal bulk-power security frameworks. They contend that cyberattacks and extreme weather events increasingly target these lower-voltage systems, and that without explicit planning requirements, states lack a consistent framework to identify and address these risks. The bill's bipartisan sponsorship and its reliance on state-led planning, rather than federal mandates, reflect a cooperative federalism approach that respects state authority while closing a documented gap in national energy security.
Opponents argue
Opponents argue that adding local distribution systems to state energy security plans creates an unfunded planning mandate that may strain smaller states and rural utilities without a guaranteed increase in federal resources to match the expanded scope. They contend that local distribution systems are already regulated by state public utility commissions, making federal planning requirements duplicative and potentially conflicting with existing state oversight structures. The 2031 sunset also limits the long-term value of the planning investments states would be required to make, potentially discouraging the sustained, multi-year commitments needed to meaningfully improve grid resilience.
