ENVIRONMENTAL PERFORMANCE condensers were installed, to compensate the Power factor (cos φ ). Due to the distribution configurations of the electrical loads in the Group’s stores, we chose to have centralised compensation installed in the general energy switchboard, for total reactive inductive and capacitive energy compensation. > Contracted power The contracted power defines the maximum instant value of electrici- ty that one of the Group’s stores can receive. The value of contracted power and the size of the electrical installation are closely connected. The contracted power is updated according to the highest power up- take value during the last 12 months (including the billing month), the uptake value being the highest active average power in the installa- tion in 15-minute periods, throughout the entire measuring period. In cases where restaurants have already made investments with a view to a more rational use of electricity, which has resulted in a re- duction in contracted power and they have applied measures to the electrical equipment so that it is switched on in a staggered manner to avoid a high increase in the electricity power uptake, the value of the contracted power will show that value for that month and in the 11 following months. The value on the electricity bill will only be re- duced after that period. 48
