Engie & TenneT: enhance delivering aFRR with different types of flexible capacity.


The successful realisation of the energy transition requires new (decentralized) sources that can offer flexibility, such as batteries, wind and solar energy, industrial installations or cogeneration. Through suppliers or a so-called ‘aggregator’, this flexibility is made available to grid operators who need to balance the supply and demand of electricity. This formed a shared long term objective for a pilot between TenneT and Engie who have already been working together in the past.
