More good news for homeowners looking to add battery storage to their solar setup as Arizona introduces financial incentives to help offset the cost. This article by Utility Dive summarizes the program benefits for residents and the environment.

Dive Brief:
-
The Arizona Corporation Commission last month approved the state's first residential battery storage program – an incentive pilot proposed in August by the Arizona Public Service Company. Around the same time, Green Mountain Power (GMP) said its growing network of stored energy in Vermont, including home batteries and other resources, has reduced customer costs by about $3 million so far in 2020.
-
The Arizona pilot will offer incentives of $500 per kilowatt of installed storage, up to $2,500, with the intent of encouraging Arizona residents to purchase and install energy storage, according to ACC commissioner Lea Márquez Peterson. The budget and size of the pilot remains to be determined.
-
Advocates for the solar and storage industries hope the new incentive will serve to encourage more residents to install storage alongside rooftop solar – pairings they say have lagged behind overall solar adoption.
Dive Insight:
Energy storage stands to make Arizona's grid more reliable and resilient, according to the state's corporation commission. The state's new pilot program, ACC commissioner Márquez Peterson said, is intended to test incentives for energy storage, while allowing electric utilities to explore potential benefits to the grid.
“Technology is still developing in energy storage and increased adoption will drive the price lower for families over time,” Márquez Peterson said in a statement. “In order to transition to a cleaner energy future, we need solutions that can not only heat and cool our homes during the hottest summers and coldest winters, but also solutions that can do so late into the evening hours, long after the sun has set.”
Arizona has several hundred thousand households with rooftop solar, according to Court Rich, vice president of the Arizona Solar Energy Industries Association, but residential storage installations have not yet caught up, with few residents choosing to install batteries even if paired with a new rooftop system. If Arizona could change that, storage stands to spur job growth and associated economic returns, he said.
“If you look at the economic impact and jobs created in the rooftop solar industry and compare this to that, you can expect similar benefits to the state,” he said.
Increased adoption of residential storage could also bring cost savings to the utilities themselves, making ambitious renewable energy targets more achievable by reducing peak demand, according to Jason Burwen, vice president of policy for the Energy Storage Association.
“If Arizona seeks to achieve a 100% clean energy future, as the Arizona Corporation Commission is deliberating on now, a peak demand reduction target with energy storage would complement those clean energy goals while helping to keep service costs affordable and empower customers,” Burwen said in an email. He indicated that numerous states have pursued a similar strategy.
In Vermont, GMP said the $3 million in reduced costs so far in 2020 "builds on more than $2 million in savings over the last two years as GMP pioneered industry-leading battery programs in partnership with its customers." The programs have reduced costs by cutting demand for electricity during peak hours.
Burwen said upfront incentives similar to the pilot to take place in Arizona have also proven "useful for accelerating early adoption, which can drive down soft costs, and for valuing services that may be difficult to price, such as local resilience.”
