Bilbao, Spain --- (METERING.COM) --- February 20, 2013 - The ALIA2 large scale power storage project led by Iberdrola subsidiary Iberdrola Ingeniería has successfully completed its first stage, with the design and construction of a system based on lithium-ion capable of storing up to 150 kW.

The ultimate goal of this initiative, which was launched in 2010, is to build a storage system based on lithium-ion with a capacity of several megawatts/hour that will be capable of delivering an amount of power five times greater than the energy stored in only 10 minutes, and will be the most powerful and reliable system available on the market when it comes into operation.

For the last three years, the Basque regional government, through the business development agency (SPRI), has been backing this project with funding channelled through research centers including IK4-CIDETEC and IK4-IKERLAN.

Other participants in the project consortium include the Basque companies Cegasa, Oldar, Ikor and Orona.

One innovative technological element of the ALIA2 project is the development of the battery pack concept, with a built-in cooling system, in a modular system where the lithium-ion cells are inserted as well as their corresponding protection systems, achieving the required voltage level and capacity. A control and protection module has also been created, which will be in charge of managing the electrical modules and will act as an interface with other modules or with the external grid system.

The new solution developed within the framework of this research is expected to be highly relevant for electric power generation and distribution companies. These companies will be able to use this system in production plants using renewable energy, substations and transformer stations to improve grid services, the manageability of the energy produced and the synchronization between production and demand.

In addition, the system, which uses 100% Basque technology, should be useful for other companies as a reliable alternative to electricity supply in the event of a supply failure in facilities such as hospitals, trains, shopping centers, etc.

The ALIA2 project is now in the testing stage, including the prototype and the auxiliary elements that will enable its integration into the electric grid.
