Abu Dhabi-based company Masdar has completed the Lockhart Solar and Storage project in California, bringing a combined solar generation and battery storage facility into operation.
The project represents an investment of approximately USD 950 million and combines 365 MW of solar photovoltaic generation capacity with a battery energy storage system having a capacity of 173.7 MW.
The development was undertaken by Terra-Gen, a renewable energy company jointly owned by Masdar and Igneo Infrastructure Partners.
The integrated facility is designed to supply sufficient electricity to meet the annual requirements of approximately 350,000 homes and businesses.
Combining solar generation with battery storage will allow electricity produced during periods of strong sunlight to be stored and made available when generation declines or demand increases.
The project highlights the growing importance of pairing renewable generation assets with energy storage infrastructure to improve the reliability and flexibility of electricity supply.
Solar power generation is generally concentrated during daylight hours, while electricity consumption can remain high during the evening.
Battery storage helps address this mismatch by shifting a portion of daytime generation to periods when solar output is unavailable.
The completion of the Lockhart facility also reflects the increasing investment in large-scale hybrid energy projects in the United States, where developers are combining renewable generation with storage systems to support grid reliability and meet growing electricity requirements.
