Scatter Wash will come online in April 2025 and provide power and energy to utility Arizona Public Service under a 20-year tolling agreement signed in May 2023.

Long-term tolling agreements – where developer-operators own the project but all its energy is provided to another company or companies under the agreement – have driven the large-scale storage market in Arizona, for both standalone and solar-plus-storage projects. While California and Texas continue to be the leading state for storage deployment, Arizona is not far behind.

In the past 12 months, Energy-Storage.news has reported on projects from other developer-operators such as Enlight (940MWh and 824MWh projects), Longroad Energy (1,200MWh), NextEra (400MWh) and Recurrent Energy (1,200MWh), to name just a few.

All are four-hour duration systems to help shift solar generation into the evening hours, and all have secured long-term tolling or power purchase agreements (PPAs) with Arizona utilities.

Energy-Storage.news’ publisher Solar Media will host the 5th Energy Storage Summit USA, 19-20 March 2024 in Austin, Texas. Featuring a packed programme of panels, presentations and fireside chats from industry leaders focusing on accelerating the market for energy storage across the country.
