Renewable energy storage: the key to accelerating green energies

At the heart of the acceleration phase of the energy transition, renewable energy storage solutions offer a range of services that help maintain a steady flow of electricity supplies. 

It is essential to keep electricity supply and demand equal at all times. Energy production remains dependent on fluctuations in intermittent natural resources such as sun and wind. The storage of renewable energies corrects this discrepancy and ensures greater stability for the power grid.

Innovate to help off-grid territories move away from fossil fuels.

Assist grid operators with the modernization of their infrastructures and enable them to put a greater emphasis on renewable energy. 

Thanks to its international presence, Akuo understands just how crucial electricity supply issues are in some regions of the world. Our teams of experts have been developing and deploying, since 2009, comprehensive energy storage battery solutions: GEM® storage and its software (EMS and SCADA).  

Recommend the renewable power storage solution that best suits the region’s requirements.

Whether the need pertains to humanitarian assistance, a one-off festive event, a temporary industrial operation, the permanent supplying of a community, or a seawater desalination plant, our energy storage containers suit every scenario, roaming or permanent.  

Mobile and turnkey (Plug & Play), they offer a range of options: 

• Intermittent energy smoothing: our batteries are combined with solar and/or wind farms to facilitate their integration into the grid.
• Frequency and voltage management: our batteries are programed to automatically support the network.
• Energy shifting (arbitrage): our batteries charge when there is a production surplus or production is cheap, and discharge when production is absent and expensive. 
• Deferral in network investment (virtual line): Installing these batteries avoids the construction of a new power transmission line.
• Creation of a grid: our batteries replace generators to form a grid and allow greater renewable energy penetration.

A true pilot of the plant, the Energy Management System (EMS) optimizes the management of the plant thanks to its ‘machine learning’ algorithms. It is based on weather and market price forecasts as well as on the digital twins of equipment updated in real time.  

Combined with Akuo’s SCADA control system, Akuo’s renewable energy storage plant is efficient, reliable and suits all possible client needs: energy smoothing, voltage and frequency regulation, energy shifting, grid forming, grid investment deferral (virtual line).  

Our approach to energy storage is based on three pillars: 

• Quality: We have been developing our solutions since 2009 and guarantee an efficient power network.  

• Safety: The safety of the environment, employees and the plant itself is our priority. 

• Social awareness: We operate in regions that are often off-grid. 

Currently, the majority of batteries are lithium-ion batteries. ADEME (French Environment and Energy Management Agency) and IRENA (International Renewable Energy Agency) have confirmed that lithium is not exposed to a major supply risk from a geological perspective. However, research is ongoing to explore every avenue that would enable us to abandon the use of limited resources.
