TenneT, along with Siemens Power, Hitachi Power, GE Grid and Royal SMIT, has signed a framework settlement value 1.9 billion euros for the adaption of substations in Germany and the Netherlands to satisfy the rising calls for of the vitality transition.
The settlement is for the provision of 110 compensation coils and 160 energy transformers. Of this quantity, 1.16 billion euros is allotted for German substations and 730 million euros for substations within the Netherlands. Every provider has been awarded roughly 1 / 4 of the entire quantity. The profitable closing of the framework settlement marks an important step in optimizing and sustaining TenneT’s transmission grid.
“The vitality transition requires an entire system overhaul, not solely with new energy traces but in addition with state-of-the-art substations. To allow the mixing of renewable energies into the transmission grid by way of the distribution grid, we want a big variety of new high-performance transformers. On the identical time, our substations will assume system providers for frequency and voltage stability, whiche had been beforehand offered by standard energy crops. For this, we require further gear similar to compensation coils.” Reflecting on the contract signing, Meyerjürgens provides: “With immediately’s signing of the framework contract, we’re sustainably guaranteeing the development and modernisation of our substations, driving the vitality transition in Germany and the Netherlands.”

The framework settlement additionally underscores the strategic partnership with the 4 suppliers. It possesses a minimal time period of two years and gives the choice to increase the contract as much as 5 instances, every for one yr. In whole, 98 energy transformers had been tendered for Germany, and 61 for the Netherlands. 68 compensation coils had been allotted for the Netherlands, and 38 for Germany. These property will probably be deployed not solely in upkeep initiatives but in addition in new development initiatives.
Main Position of substations
Substations could be in comparison with freeway entrances and exits. They join TenneT’s energy highways with the principle roads of the distribution grid operators. The core elements of each substation are transformers, which remodel the electrical energy to a decrease voltage stage. More and more, the transformers additionally work in the wrong way as a way to transport domestically generated inexperienced electrical energy. Subsequently, substations fulfil a twin function: they provide the native area with electrical energy by remodeling the electrical energy from the transmission grid all the way down to the voltage of the distribution grid and distributing it throughout the world. Concurrently, they remodel domestically generated renewable vitality from the distribution grid into the excessive voltage stage of the transmission grid, transporting the electrical energy to demand centres.
As a part of the vitality transition, substations are more and more taking over system providers for frequency and voltage management. An essential device for voltage management are compensation coils. Their foremost operate is to supply inductive reactive energy to the grid, compensating for capacitive reactive energy. Reactive energy is important for the move of electrical energy. It’s used to regulate the voltage within the energy grid as wanted, both elevating or reducing it to keep up a secure voltage stage. Nevertheless, reactive energy reduces the capability of the facility grid for usable lively energy, which is the vitality that really reaches the buyer. Subsequently, you will need to keep the fitting ratio of lively to reactive energy: if the reactive energy element is just too low, voltage drops, limiting the transmission of electrical energy. If the reactive energy element is just too excessive, it might block the grid, lowering the transport of lively energy. Compensation coils assist keep this stability. Supply: TenneT
