Arizona utility regulators approved new clean-energy rules on Friday that will require electric companies to provide 100% carbon-free energy by 2050, with interim benchmarks between now and then.
The final rules passed Friday include a host of other requirements, from energy efficiency requirements and battery storage policies for utilities.
But because of some last-minute dealmaking to ensure the rules get three needed votes to become effective next year, they do not include a requirement for utilities to use a set amount of renewable energy, such as solar and wind, to reach the carbon goals.
