The proposed bill, known as the "Survey All Vulnerable Electric Transformers Act," mandates that electric utilities and developers assess and report the vulnerability of high-voltage transformers to geomagnetically induced currents (GICs) caused by geomagnetic disturbances (GMDs) and high-altitude electromagnetic pulses (HEMP). The bill requires covered entities to conduct a technical assessment of all relevant equipment by January 1, 2027, utilizing specific modeling standards and accounting for transformer age and condition. Additionally, the bill outlines detailed reporting requirements, including the submission of a comprehensive report to the Department of Energy and other relevant authorities within 180 days of the act's passage.

Key provisions of the bill include the definition of "covered entities" and "covered equipment," as well as the establishment of operational standards that prohibit reliance solely on load shedding or reactive power supply as mitigation strategies. The bill emphasizes the importance of confidentiality, ensuring that sensitive data related to critical energy infrastructure is protected under specific protocols. The act is set to take effect on July 1, 2026, and aims to enhance the resilience of the state's electric infrastructure against potential threats from solar weather events and electromagnetic disturbances.
