EDP Renovaveis (ISIN ES0144580Y14) stock is underpinned by new growth in the United States after its North American subsidiary completed the Sandrini Energy Storage project, a 92 megawatt (MW) battery system in Kern County, California, announced on August 18, 2026. The project adds a 368 megawatt-hour (MWh) battery capable of powering more than 22,000 homes and supports long-term contracted revenue from the US market.
New 92 MW battery boosts US footprint
According to an August 22, 2026 project update, EDP Renewables North America has finished the Sandrini Energy Storage facility with 92 MW of capacity and 368 MWh of storage. This report notes that the installation is located in Kern County, California, and is designed to deliver stored energy during peak demand periods.
Local media coverage on August 22, 2026 describes a joint event where the project partners celebrated the completion of Sandrini Energy Storage, highlighting that the 92 MW / 368 MWh system has the capacity to power the equivalent of more than 22,000 California homes. This coverage underscores the system's scale and its role in supporting regional grid reliability.
Contracted offtake and portfolio implications
The Sandrini project includes a long-term offtake agreement under which a regional energy authority will purchase all of the battery system's output. The same project description states that the authority has committed to buying all energy from the 92 MW / 368 MWh asset, effectively locking in utilization of the storage capacity.
For EDP Renovaveis, adding 92 MW of battery capacity on top of its existing wind and solar base in North America supports a strategy of integrating storage to smooth renewable production. With the Sandrini system capable of supplying electricity to more than 22,000 homes, the project enhances the company's presence in California, one of the largest and most policy-supportive clean energy markets in the US.
Clean energy environment supports investment case
Recent sector commentary on August 23, 2026 highlights that US clean energy investment is on track to exceed $180 billion in capital expenditure this year. The report on the investment outlook notes that management at EDP sees the current period as one of the most favorable for renewable energy investment in the US in the past two decades, reflecting policy support and customer demand.
The completion of a 92 MW / 368 MWh battery in California positions EDP Renovaveis to capture a share of this expanding investment cycle, especially as grids increasingly require flexible storage to integrate higher levels of wind and solar. The ability of Sandrini Energy Storage to power more than 22,000 homes with stored energy provides a concrete example of how storage assets can generate stable revenue while supporting decarbonization goals.
Battery storage as a strategic product
Sandrini Energy Storage itself stands out as a representative product in EDP Renovaveis portfolio of grid-scale assets. With 92 MW of power and 368 MWh of energy capacity, the installation can charge when wholesale prices are low and discharge during higher-priced peak hours, helping balance the local grid.
As more regions adopt similar large-scale batteries, the operational experience gained from running a project capable of serving more than 22,000 homes can inform future designs and contracts. For investors, the Sandrini project illustrates how EDP Renovaveis is moving beyond pure wind and solar generation toward an integrated renewables and storage business model.
EDP Renovaveis stock and listing
EDP Renovaveis shares trade in Europe, giving investors exposure to a global portfolio of wind, solar and battery assets including the newly completed 92 MW Sandrini Energy Storage project in California. The combination of contracted storage capacity, a growing North American footprint and a supportive clean energy investment backdrop in 2026 shapes the risk-reward profile for EDP Renovaveis stock.
