Avantus: $300 Million Construction Financing Secured For Arizona Solar And Energy Storage Project

By Amit Chowdhry ● Mar 5, 2026

Avantus announced it has closed more than $300 million in construction financing for the Kitt Solar and Energy Storage Project in Arizona. The financing was arranged with Banco Bilbao Vizcaya Argentaria (BBVA) and Canadian Imperial Bank of Commerce’s New York branch (CIBC).

The Kitt project is located in Pinal County within the City of Eloy, Arizona. It will feature 100 MWac (130 MWdc) of solar generation capacity along with a 400 MWh battery energy storage system. The financing package includes construction funding, a tax equity bridge loan, and letters of credit.

Currently under construction, the project is expected to create up to 500 construction jobs and is targeted to reach commercial operations by the end of 2026.

Once operational, the project will have the capacity to serve up to 32,000 homes in Arizona through a power purchase agreement with Arizona Public Service (APS). The integrated battery storage system will store solar energy generated during the day and deploy it during peak evening demand periods or extreme weather events, helping strengthen grid reliability as electricity demand rises across the state.

The project is also expected to generate more than $25 million in local tax revenue throughout its lifetime, benefiting schools, infrastructure, and public services in the surrounding communities.

Engineering, procurement, and construction services are being provided by RES. The battery energy storage system will utilize Fluence’s Gridstack Pro technology for battery integration.

Avantus develops, owns, and operates utility-scale clean energy projects across California and the Desert Southwest. The company’s development pipeline includes approximately 24 GWdc of solar capacity and 75 GWh of energy storage projects across the western United States. According to the company, its portfolio has the potential to deliver dispatchable clean energy to about 17 million Americans.
