A peak demand charge is a fee an electric utility charges commercial and industrial customers who consume large amounts of power.

Usually, the typical method of curtailing these additional fees of peak demand is to encourage the consumers to use less energy during peak hours, or to move the time of energy use to off-peak times such as nighttime and weekends.

Some customers need large amounts of electricity once in a while – others, almost constantly.

ECO-H’s peak demand management does not decrease total energy consumption, but could be expected to reduce the need for investments in networks and/or power plants for meeting peak demands.
