Saving opportunity: simple and easy

Controlling kW demand for industrial, commercial and institutional energy users depends solely on the customer.

For this reason, I consider it a very interesting opportunity, little explored in Brazil.

The power bill issued by the local concessionaire, whether for a regulated or deregulated energy user, includes demand, which typically represents 25% of the total.

Reducing this demand is the suggestion to be considered. This because the "registered" demand is the largest 15-minute-integrated measurement (there are almost 3 thousand in a month).

The maximum demand occurs typically once a day. So the strategy is - on these rare occasions - to limit selected loads for a few minutes and that's it!

The potential savings are significant. My experience indicates that it is feasible in most cases to reduce 30% of the difference between the current maximum demand and the average demand. In large numbers, it means saving one monthly energy bill per year!
