Energy - About
Energy is defined as power consumed over time. In electrical distribution systems, the unit of time is
one hour for all energy measurements and the kWh is the basis for payment for buying and selling
energy.
The Energy section focuses on the flow of energy or power both within a system (active, reactive) as
well as the flow of power to and from the system to the grid (delivered or received). In this section
you will be able to:

Review the overall Consumption & Demand of your Electrical System

View a Detailed Breakdown of Energy Flow Components

Review Statistical Information Regarding Measurement Status

Consumption & Demand
Energy is produced and consumed within an electrical distribution system. Some sites produce
energy for the grid (Received Energy), others consume energy from the grid (Delivered Energy), and
still others both consume and produce energy for/from the grid. The Net Consumption is the
difference between energy that is used and produced. Therefore, a negative value for Net
Consumption indicates that the site is producing more than it is consuming, or a received net
consumption.
The Consumption & Demand window is a quick look at some of the key components of the

Information
window. Here you find a cross-sectional summary view of the amount and makeup
(Active or Reactive) of the Net Energy (Received – Delivered) produced/consumed by a site.
A Demand is an arbitrary measurement of average power usage per configurated unit time. A
demand is measured in units of power even though a time element does exist, while Peak Demand is
the highest demand calculated since the last demand reset. Refer to Energy Meter in the
Advanced
Settings section to reset the demand of your energy meter.
