 Renewables are the future, but what if there's no wind or the sun isn't shining? At Total Energies, we've got the solution. Storage. The extra resource these energies need to balance the production and use of electricity. And this is what that means. At Dunperk, we have built and commissioned the largest site for battery electricity storage in France. Its capacity is 61 megawatts, which keeps the electricity supply going for one hour in over 200,000 homes. France has the target to develop the renewables in the electrical mix up to 40% by 2040. As such, renewables are bringing intermittency, variability on the grid. We need to have storage solutions in order to balance the grid, which means just adapting the consumption with the generation at the same time. In Dunperk, Total Energies teams work together on the design of the installation to the supply of batteries by its SAFT affiliate, via the management of data estimating the use and sale of electricity and the storage capacity. The result was optimized project management and compliance with the highest standards of quality and safety. We have built a power plant, a battery energy solution system. It is constituted by 27 SAFT containers, high energy intention product, which are connected with the power conversion system to the grid. Let's zoom in on the heart of the system. The containers, 20 feet long and 28 tons. They use lithium ion technology and deliver energy performance at the top end of the market. The key advantage of lithium ion batteries are several. One is the high density. Today batteries can reach up to 400 watt hour liter in a very dense pack. Another advantage is that they can live long. Today the life cycle is reaching up to 20 years. Another advantage is the efficiency. Today lithium ion batteries are reaching 98% efficiency, which means only 2% of the energy is taken from the process from charging to discharge. Also, lithium batteries are very cost effective. The result is an innovative bespoke site that helps to integrate renewables into the energy mix. And as our solution can be replicated all over the world, we have every reason to store tomorrow's energy today.
