Welcome at CRESS
Solar and wind parks do not always generate electricity at the time when it is needed - and often too much energy, which can not be used immediately. This results in network congestion and power supply fluctuations, which can be corrected only by reducing or adding fossil or nuclear-generated electricity. But the performance of power plants can not be reduced or increased quickly or even shut down. The result is power fluctuations. The link between renewable and conventional energies are ESS (energy storage systems). ESS ensure that excess power can be stored and used for later use.
