January 23 (Renewables Now) - Regional electric utility Arizona Public Service Co (APS) has set an objective to achieve a resource mix of 65% clean energy by 2030, including 45% renewables.
The Phoenix-based company, the principal subsidiary of Pinnacle West Capital Corp (NYSE:PNW), currently has an energy mix that is 50% clean and will be pursuing the goal of supplying solely carbon-free electricity to customers by 2050.
The utility, which serves some 2.7 million people in 11 of Arizona’s 15 counties, said it will rely on more renewable energy resources and developing technologies, nuclear power and energy efficiency programmes. It plans to end all coal-fired generation by 2031, seven years sooner than expected.
APS said it will continue to rely on some natural gas in the near term, though, in time, it anticipates technological advances to eliminate the need to use this energy source as a supplement to renewables. The company will also continue to modernise the electric grid, add more energy storage to solar farms and electrify the state’s different economic sectors such as transportation.
A year ago, APS announced initiatives that would add 850 MW of battery storage and at least 100 MW of new solar power production capacity by 2025. In September 2019, it also launched two separate Requests for Proposals (RfPs) targeting up to 150 MW of solar and 250 MW of wind power.
