FACT SHEET FOR S.B. 1501 
 
grid security; cybersecurity; reviews; commission 
Purpose 
Requires the Arizona Corporation Commission (ACC) to conduct an annual grid security 
review of a plant and make outlined assessments and evaluations when conducting the review. 
Requires the ACC to require investor-owned utilities to rectify deficiencies that were identified in 
the grid security review. 
Background 
The ACC regulates investor-owned or privately-owned utilities that provide gas, water, 
electricity or telephone service (ACC). The ACC has the power to inspect and investigate the 
property, books, papers, business, methods and affairs of any corporation whose stock is offered 
for sale to the public and any public service corporation doing business within Arizona (Ariz. 
Const. art. 15 § 4). The ACC has the power and authority to enforce its rules, regulations and 
orders by the imposition of such fines as the ACC may deem just (Ariz. Const. art. 15 § 19). 
The Arizona Constitution allows the Legislature to enlarge the powers and extend the 
duties of the ACC and to prescribe rules and regulations to govern proceedings by and before the 
ACC (Ariz. Const. art. 15 § 6). 
There is no anticipated fiscal impact to the state General Fund associated with this 
legislation. 
Provisions 
1. Requires the ACC to conduct an annual grid security review of a plant. 
2. Requires the ACC, in conducting the review, to: 
a) research and evaluate the generation and grid management technologies that will 
accommodate a two-way flow of electricity and that protect against a physical attack and 
cyberattack; 
b) assess emerging technologies, including distributed energy resources, microgrids and new 
technology battery storage;  
c) evaluate new information technology systems and how protections are implemented; 
d) require investor-owner utilities to rectify deficiencies that were identified in the grid 
security review and develop security plans that evaluate and consider the time and costs 
that are associated with implementing changes; and 
e) review, every two years, the cybersecurity and grid protection protocols. 
3. Requires the outlined security plans to include potential funding sources from private capital 
investment for energy development.  FACT SHEET
