Normally, the frequency-forming power generator in the Fair Grid is adjusted to just below 51 Hz. If the load suddenly rises or the feed-in power from solar or wind power plants drops, the frequency will initially drop a little, the motor load will decrease, and thus the balance between power generation and consumption will be adjusted. In the frequency range between 51 Hz and 49 Hz there is 4% free and quickly available load buffer, which does not have to be compensated in the short term. As a result, Fair Grid requires less short-term load buffer.
