STORAGE: a key area of expertise in the development of renewable energy, this technology has been fully mastered by Akuo Energy, which was one of the first operators to deploy it on an industrial scale.
With 29MW of photovoltaic projects coupled with 29MWh of battery storage in operation since 2014, Akuo Energy is the main global player in the field of combined large-scale solar and storage projects. Following years of research and development, Akuo Energy’s team has been able to adapt storage technology to an industrial scale, thus helping to overcome the issue of intermittence in photovoltaic energy. By demonstrating that grid stability is no longer a drag on renewable energy, Akuo Energy has shown the importance of the role that renewable resources have to play in energy transition. This has opened the path to industrialized storage.
In 2018, Akuo was the winner of the Madinina storage project in Martinique with a capacity of 12MWh to provide an aritrage service that will generate savings on the park's production costs by optimizing the use of resources. The group is also currently working on two third-party storage projects in Tonga with a capacity of 5MWh and 23MWh respectively. Tonga 1 and 2 will help meet the need for the archipelago to increase its storage capacity to support the increase in the share of renewable energy in the electricity mix. Akuo is also present in New Caledonia with a 3MWh project associated with a 6MW solar project currently being financed.
STORAGE: HOW DOES IT WORK?
The innovative development of industrial-scale power storage is the fruit of work carried out by teams at Akuo Energy, who have developed, internally and in cooperation with electricity suppliers, an Energy Management System (EMS) based on extremely accurate weather forecasting, to predict the next day’s output from solar farms.
Complex software incorporates historical weather data stretching back more than a decade, and demonstrating the perfect predictability of weather events. Based on this information, batteries allow surplus production to be absorbed or production shortfalls to be covered in order to supply the grid with entirely reliable power (click on the video link to find out more).
