Since 2020, Wattway has entered a new phase in its deployment. The Wattway Pack offer is marketed in France, with more than 50 sites deployed by the end of 2022, and internationally via partners in Japan, Germany, Switzerland, Italy, etc. At the same time, work is continuing to perfect the technology in two priority areas: better understanding of its lifespan in relation to the environment and traffic conditions, and working to reduce costs. On this last aspect, our objective is clear: to produce self-consumption electricity at a lower cost than that which a site can buy from the grid, thanks to the Wattway Plus offer.

A first step has been taken by dividing the price of the solution by three in 2021 and this is only the beginning. The cost-cutting approach is continuing along two major lines, increasing the energy produced per square metre and reducing the production costs of the solution and its installation. This involves optimising the components (cells, materials), the electrical architecture (from the slabs to the inverters) and the installation processes, in particular through the mechanisation of the installation, which is a major challenge for future projects.

The development of a technology of this magnitude is complex and requires progress in successive stages, identified and programmed in a roadmap for the coming years. Each major step is validated by implementation at pilot sites, such as the Thorn Turn site in 2021. We expect to see further major pilot sites in 2023 and will keep you informed.

There are still a few key steps to go before we are on target for the deployment of a new, more resilient, more integrated self-consumption electricity solution, without land artificialisation!
