Energiespeicherausrüstung des Northwestern Power Grid
The large-scale 220 MW project in North Rhine-Westphalia, which was officially presented in November 2022, is to break new ground for the use of storage technologies at RWE''s power
Does the German power grid need large-scale storage?
Through mathematical modeling and optimization, we simulate the German power grid and investigate the requirements of on-grid large-scale storage. Different scenarios are evaluated up to 2050, when 80% of the gross electricity consumption is planned to be provided by renewable energy.
Does the power grid in Germany underestimate storage demand?
In this approach, optimal charge-discharge strategies are investigated, aimed at maximizing battery lifetime, which ultimately impacts the economic feasibility of such systems. Another aspect of the model that can skew the results towards an underestimation of storage demand is that the power grid in Germany is not explicitly modeled.
How will RWE use the storage capacity to stabilize the power grid?
RWE wants to use the storage capacity to stabilize the power grid. It said its new lithium-ion batteries can generate 220 MW over the course of an hour. It plans to virtually connect the storage facilities with its German power plants, so it is possible to optimally control the units, individually and as a group.
How can energy storage help a power grid?
Dispatchable generation (natural gas, pumped hydro plants), improvements in grid efficiency to remove bottlenecks and demand-side management all come at play to mitigate the effects of fluctuating electricity generation, but another powerful tool is gaining more and more ground as far as future power grids are concerned: energy storage (ES).
How reliable is Germany's power grid?
Germany’s power grid ranks among the most reliable in the world, despite an increasing share of fluctuating renewable energy sources. The government has made the extension of the grid a priority to maintain this high level of resilience.
When will RWE build a power grid?
Construction is scheduled to start in 2023, and commissioning is planned for 2024. RWE wants to use the storage capacity to stabilize the power grid. It said its new lithium-ion batteries can generate 220 MW over the course of an hour.
