Smart energy
The instability of the energy grid increases. Due to the raising share of energy generated by solar panels, windmills and fuel cells, it is not easy to estimate the correct amount of energy consumption of a coming period,. It becomes more and more difficult (and more expensive) to adjust the energy production.
In order to keep these power fluctuations on the grid within manageable limits, energy storage can help. A good prediction can result in a perfectly coordinated and therefore profitable (limited) energy storage.
