Load duration and an hours-at-load bell curve

Visualize the peakiness of your meter’s load curve, and know what the distribution looks like for your meter’s hours at load across kW demand buckets.

These load duration graphs are only available for Meter data, and are based on the trailing twelve months (or with whatever data is available, if there is less than a year’s worth of data).

Load duration curves–steeper the peakier

This load duration curve displays a cumulative percentage relationship: as you trace the cursor over the line, you will see a demand kW reading and a percentage reading. For example, a 10% at 600 kW reading tells you that 10% of the time, the meter demand is reading 600 kW or greater.   

If the load duration curve is steep, that suggests certain demand management strategies might be particularly effective.

We walked through five of these charts in greater detail on this Pricey curves is load duration blog post.

Hours at load–time spent in demand kW buckets

The hours at load graph adds a new layer of detail to the shape of the bell curve of your meter’s load curve. How many hours over the past year were spent in a particular 20 kW demand bucket?

Trace your cursor over the bars on the graph for an individual hours reading in each demand kW bucket.

Budget forecasts

Gridium uses historical data from your buildings to forecast future energy use and costs. However, the past isn’t a perfect guide to the future. You can use the Gridium budget forecast as is, without further modification, or you can treat it as a starting point onto which you can layer further planning assumptions. This guide will help you understand the forecast and make any desired updates.
