There must be a constant current frequency in an energy grid for it to function properly. In short, this means that the power being fed into the grid must equate to that being drained from the grid.

Having said that, in Austria there are pumped storage power which can be used to store energy but these are unable to provide the required additional capacity for more electricity produced from renewable resources. Such facilities are usually hydropower plants located in mountainous regions where environmental conservation and preservation requirements limit their further expansion. As such, further expansion of pumped storage power plant capacity is close to reaching its upper limit and still far short of being able to meet modern needs.

While this need for a constant power supply may change in the future, current technology has few other practical options for sufficient electricity to be stored to allow us to escape this need to balance energy in and energy out. Ideas and concepts such as using the batteries of electric vehicles as a buffer or the production of hydrogen in power-to-gas-facilities have not yet been sufficiently developed to be of practical use. Therefore, electricity that has been produced from renewable energy sources must be consumed immediately, making it imperative to transport this electricity to consumers as quickly and efficiently as possible.
