Avantus Signs 20-Year PPA for Rexford 2

• Avantus inks a 20-year deal for Rexford 2: 200MW solar plus 200MW/800MWh storage in Tulare County—fueling ~84,000 homes. Ops by late 2028, deliveries May 2029.

US clean energy developer Avantus has signed a 20-year power purchase agreement with California community choice aggregator Clean Power Alliance for the Rexford 2 project in Tulare County. The deal covers a 200-MW solar facility paired with a 200-MW/800-MWh battery energy storage system.

Avantus expects the system, once operational, to power about 84,000 homes in Southern California. Fluence will supply its Smartstack battery technology. Construction is set to start in 2027, with commercial operations targeted for late 2028 and electricity deliveries beginning May 2029. Avantus will own and operate the project as an independent power producer, while expanding a pipeline of about 13 GW of solar and 44 GWh of storage across California, Nevada and Arizona, targeting 5 GW operational by 2030.

What does Avantus’ 20-year PPA mean for Rexford 2 solar-plus-storage in Tulare County?

• A 20-year PPA means Rexford 2’s output under long-term contracts is largely “locked in” for the duration of the deal, creating revenue visibility that supports financing and project bankability.
  
• Clean Power Alliance’s role as the offtaker shifts the core credit and offtake risk from the developer to a utility-style purchaser, helping stabilize cash flows for Avantus over two decades.
  
• The contract terms tie electricity payments to long-running performance expectations for both the solar generation and the battery system—so the storage component is not just an add-on, but a revenue-relevant asset.
  
• Because the PPA is structured around a solar-plus-storage configuration (200 MW solar paired with 200 MW / 800 MWh storage), it supports revenue from both energy output and grid-support services enabled by storage dispatch (for example, shifting solar power to higher-value time windows).
  
• For Tulare County, the long PPA horizon underwrites sustained construction and operational activity tied to a project expected to deliver power for many years, rather than operating under short-term market exposure.
  
• The agreement is expected to help smooth price volatility impacts that typically affect standalone renewables without long-dated contracts by providing a predictable pathway to monetize the facility’s production.
  
• The scale—200 MW of solar and 800 MWh of storage—means the PPA effectively commits a meaningful chunk of clean capacity to Clean Power Alliance’s portfolio, strengthening its ability to meet demand while reducing emissions.
  
• By securing a long-term sales route for Rexford 2, Avantus is positioned to demonstrate repeatable contracting and development execution for future battery-plus-solar projects in the region.
  
• The 20-year structure typically supports the use of warranties, performance guarantees, and lifecycle planning for the battery system—important for meeting output targets over time.
• For ratepayers served through Clean Power Alliance’s electricity supply, the PPA can provide long-term procurement certainty for a portion of their clean energy needs, which can influence how reliability and renewable integration costs are managed over time.
