Saft and Acciona Energia have joined forces on a Eurogia+ project to improve the viability of photovoltaic power plants. The project will demonstrate the technical and financial benefits of using a containerized energy storage, conversion and management system to provide grid ancillary services as well as power management to help even out the plant productivity.
As part of the initial project, Saft will develop a modular lithium-ion (Li-ion) battery system to be housed inside a six-metre container designed for industrial applications at a photovoltaic plant, based in Tudela, Spain. The container includes active temperature control systems and a fire suppression system.
“With the ever increasing contribution of renewables in our electricity mix, it is of crucial importance to improve the electrical behaviour of renewable power plants. The decision to work with Saft on this project was a natural one,” said Miguel Arrarás, solar PV development director Acciona Energia. “In addition to their batteries high energy-efficiency and reliability, their containerized solution is ideal when it comes to addressing environmental constraints of field deployment. Saft’s knowledge of designing, manufacturing and controlling large energy storage systems means it will be a key contributor to the partnership.”
As part of the system, Saft will be able to offer the customer 1.1MW power at up to 1,000V. Each container is easily scalable and will interface with existing power conversion devices.
“We are delighted to be working with Acciona on this groundbreaking project,” said François Bouchon, director of the energy storage business unit at Saft. “We believe the introduction of containerized energy storage makes photovoltaic and other renewable energy source plants an increasingly attractive option for the future. The ability to address issues around reliability, stability and power management is a huge step for the power industry in its efforts to integrate ecological concerns.”
