2. Avoidance of standby losses.
5 % to 8 %
Total 8 % to 15 %
Reduction in CO2 emissions due to
less need for peaking plants.
Reduction in bills due to
1. Consumption in low price tariffs
rather than high price tariffs.
2. Lower prices because of more
efficient energy supply and
lower operational costs.
