Electronic systems provider AEG (AEG) working alongside Spanish utility Iberdrola and European research foundation Tecnalia, has delivered a lead-acid battery energy storage system (ESS) located at Iberdrola’s substation in Vitoria, Spain.
The grid-connected system designed for peak shaving times. The ESS is designed to have an energy capacity of 0.6MWh and allow the utility to monitor the grid load as well as to integrate the locally generated wind power.
AEG will test a number of its new products for stabilising and levelling the grid. These include a wireless battery management system, a storage converter and the first field-testing of AEG’s local monitoring unit.
The ESS involved the construction of two buildings: one houses the battery, while the monitoring system, communications and power conversion are located in the other.
The project Sistema de Almacenamiento de Energía a Gran escala para la Red Eléctrica (SAGER) has a budget of €1m ($1.2m) and is supported by GAITEK, a programme of the Basque Agency for Enterprise Development to support R&D ventures.
