Electric Thermal Energy Storage
GWh scale & cost competitive
ETES costs will be significantly lower than classic energy storage solutions. Even at the pilot stage, a commercial project at GWh scale would be highly competitive compared to other available storage technologies. Economies of scale will bring substantial reductions in capital expenditure, while increasing the storage rating. Implementation of ETES Switch will lead to a further cut in CAPEX of around 50%. What’s more: charging power, storage capacity and discharging power are independently scalable.
Making ETES commercially available.
- The first test site with 5 MWh capacity was implemented in 2014
- Proof of system will start operation with a 120 MWh capacity in 2019
- A pilot plant with an output of around 50 MW will follow in 2020
- Commercial rollout is planned with an output of several hundred MW
