The Spanish company Acciona Energia SA has signed a collaboration agreement with Saft, as part of a project labeled Eurogia +, to improve the viability of power plants running on solar energy and other renewable energy sources.

The project will demonstrate the technical and financial benefits provided by the use of a container storage, conversion and energy management for the provision of ancillary services to the network and energy management to smooth production.

Under the initial draft of PV plant in Tudela (Spain), Saft will develop a lithium-ion (Li-ion) modular, to be housed in a container of six meters long, designed for industrial applications. The container includes active control systems for temperature and fire suppression. Offering a very high efficiency, the Li-ion does not require long-term maintenance and can easily measure the state of charge in use.

The project also aims to integrate solar farms to the grid as conventional power plants, with a new control system, including testing new photovoltaic technologies that develop Acciona Energia. The ultimate goal is to reduce the cost of energy and provide extra services as ancillary services, improving network stability and security of backup power.

“With the ever-increasing share of renewables in our energy mix, it is of utmost importance that we improve the behavior of electric power plants with renewable energy … Besides energy efficiency and reliability of the Saft batteries, its containerized solution is ideal for coping with environmental constraints of the deployment on the ground “said Miguel Arrar, Solar PV Development Director, Acciona Energia.

With this system, Saft will be able to offer customers a power of 1.1 MW up to 1000 V. Each container is easily adaptable and will be connected with devices for converting energy in place.
