en.Wedoany.com Reported - Spanish engineering and construction company Aldesa has secured a contract to build a hybrid utility-scale renewable energy project in Mexico, comprising 420 MWp of solar photovoltaic capacity and a 150 MW battery energy storage system. The contract covers design, procurement, and construction, and the identity of the project owner has not been disclosed.

The battery energy storage system provides electricity during peak demand periods or when solar generation is reduced, while also stabilizing grid fluctuations from variable renewable energy sources, thereby enhancing grid flexibility and reliability. This contract award indicates that investment in the renewable energy sector continues despite challenges in Mexico's regulatory environment, while also enriching Aldesa's growing portfolio of large-scale solar projects in Latin America.

The rapid response capability of batteries can smooth short-term solar fluctuations, helping to mitigate voltage and frequency variations caused by cloud cover or rapid changes in photovoltaic output. The peak-shaving capability enables the hybrid plant to supply additional electricity during high-demand periods, alleviating pressure on generation resources and reducing the risk of local supply shortages. Dispatchable output enhances grid reliability by providing controllable power on demand. Combining energy storage with solar power reduces curtailment, helping the grid accommodate higher renewable energy penetration with fewer operational constraints. Frequency support provided by battery operation helps maintain system balance, which is particularly important in systems with limited spinning reserves or significant renewable energy fluctuations.
