Storage: the cornerstone of the acceleration in renewable energies

At the very heart of the energy transition’s acceleration phase, storage solutions offer a range of auxiliary services enabling a regular electricity supply to be maintained. 

Supply and demand are not always balanced, and energy production is dependent on fluctuations in the intermittent natural resources that are sun and wind. It is therefore essential to maintain a constant voltage and frequency that, when not maintained, damage electrical devices. 

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 energy 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 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 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.
