Lithium batteries vs KaprunHow to compare lithium batteries with a pump storage power plant. What would it cost to built Kaprun new? How is the compare of costs?
30000 cycles, 20 years and by us estimated 300.-EUR per kWh. Storage tasks in the grid are mentioned as important target market. But how to compare this data with a typical storage power plant ? Kaprun becomes just right now extended with Limberg II. Just right now are 130 MW pumping power and 330 MW electric power generation installed. With a new connection of the existing of the two existing artificial lakes Moserboden and Wasserfallboden, Kaprun will be 480 MW more powerful. 480 MW more pumping, 480 MW more power generation. This extension makes 365 Million EUR. It would be much more expensive, when there would not be the 2 existing artificial lakes.
When daily 4 hours power production with 480 MW is the essential feature of Kaprun Limberg II, this essential feature is representable with 2 GWh lithium batteries for 600 million EUR,
How expensive would be a complete new built pump storage power plant? How much influences the lower efficicency - 85% pumping, 90% electricity generation and the long delivery lines - the rentability? But most important, how often would it be possible to built a storage power plant like Kaprun? The need for storage technology is at 80% share of wind and sun about 2 magnitudes greater than at atomic power. Electric power storage is at wind and solar power no question of cost optimzation, but a question of existence.
Storage power plants would not be built where it is geological possible, but where the storage is best placed. For example lithium battery in the cellar, photovoltaic on the roof. The battery building beside the wind power plant. |
