ARIZONA STATE SENATE
Fifty-Third Legislature, Second Regular Session
AMENDED
(NOW: renewable energy standards; corporation commission)
Purpose
Subject to voter approval, amends the Arizona Constitution to require affected utilities to generate at least 50 percent of their annual electricity sales from renewable energy sources by 2030. Requires the Arizona Corporation Commission (ACC) to evaluate specific factors to determine whether to implement the renewable energy requirements.
Background
The ACC, established by Article XV of the Arizona Constitution, has the authority to prescribe just and reasonable classifications, rates and charges collected by public service corporations. Additionally, the ACC must adopt reasonable rules, regulations and orders governing the transaction of business by public service corporations.
Generally, public service corporations include corporations engaged in furnishing gas, oil or electricity for light, fuel or power or in furnishing water for irrigation, fire protection or other public purposes (Ariz. Const. art. XV, § 2).
In 2006, the ACC approved the Renewable Energy Standard and Tariff (REST) which requires regulated electric utilities to generate 15 percent of their energy from renewable resources by 2025. Utility companies must file annual implementation plans showing compliance with the REST rules, including incentives offered for customers who install solar energy technologies for their homes and businesses (A.A.C. R14-2-1804). Renewable energy resources include biogas, biomass, geothermal, solar and wind technologies (A.A.C. R14-2-1802).
Distributed renewable energy resources are technologies located at a customer’s premises that displace conventional energy resources that would otherwise be used to provide electricity to Arizona customers. They include biogas electricity generators, biomass thermal systems, solar devices, combined heat and power systems and wind generators of 1 MW or less (A.A.C. R14‑2‑1802).
There is no anticipated fiscal impact to the state General Fund associated with this legislation.
