The proposed bill would amend current statutes by requiring the Arizona Corporation Commission (ACC) to conduct a grid security review at least every two years or as part of its integrated resource planning process or biennial transmission assessment. This review would necessitate that each investor-owned public service corporation evaluate technologies to protect against physical and cyberattacks, assess the risks associated with electromagnetic pulses, and update their cybersecurity and grid protection protocols for ACC review. The ACC would also confirm that these corporations have active protocols in place and assess the adequacy of submitted protocols.

Additionally, the bill stipulates that all information related to the review, including plans and protocols, would not be open to public inspection. It emphasizes the state's policy to diversify energy generation assets and prepare for electromagnetic pulse effects through coordinated government and private-sector efforts. The bill allows the ACC to adopt and modify the review process as deemed reasonable and in the public interest, thereby enhancing the regulatory framework surrounding grid security in Arizona.
