Saving opportunity: simple and easy

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!

The Energy Central Power Industry Network is based on one core idea - power industry professionals helping each other and advancing the industry by sharing and learning from each other.

If you have an experience or insight to share or have learned something from a conference or seminar, your peers and colleagues on Energy Central want to hear about it. It's also easy to share a link to an article you've liked or an industry resource that you think would be helpful.
