An Arizona scheme to study the use of energy storage and smart inverters in integrating solar to the grid has contracted the deployment of 4MW of AES Energy Storage’s lithium battery systems.
While regulators in the state are poised to rule next week on the value of solar to the network and consumers, ending what PV Tech reported today amounts to “years of drawn-out discourse”, execution of this project, for utility Arizona Public Service (APS) is already underway.
The 4MW of storage will be deployed as two separate 2MW installations of AES’ Advancion energy storage systems. They will form part of APS’ ongoing ‘Solar Partner Program’, which evaluates the possibilities for integrating a high penetration of PV on the grid.
The utility has already put 10MW of PV onto more than 1,500 customers’ rooftops through the programme. Participants receive a US$30 monthly bill credit for 20 years and do not have to pay for panels themselves. APS claims this will help inform them and other utilities around the country on how smart inverters and storage can play a part in lowering emissions, maintaining reliability of the system and best manage peak demand while renewable energy assets increase their share of generation.
