Energy Analytics for Seasonal Energy Loads

My last Energy DNA blog post we showed how Energy Analytics could have helped avoid expensive demand charges at a vegetable packing facility.  This post describes how energy analytics can help with seasonal energy loads.  Recall that the colorful Energy DNA chart displays energy intensity by date (vertical axis) and time of day (horizontal axis).

ENERGY ANALYTICS CASE STUDY 2: EXTREME SEASONALITY

Our next client is a nut processor.  Here we see extremely seasonal load, reflecting heavy fall post-harvest operations.  But there’s something very interesting happening in the off-season:  Can you guess what the green football shape represents?

Spot the lighting loadLighting – or more precisely, an absence of lighting.  The data suggest that lighting consumes most of this processor’s energy during off-peak hours from January through June.  As the days grow longer less lighting is needed, and the facility’s energy intensity is lower (green) for a longer period.  A site visit confirmed that this facility had many HID and older T8 fluorescent lamps… an easy savings opportunity.

It’s time to replace your HID lighting.  Modern LED and florescent lamps offer better light quality and performance,  throw less heat, consume far less energy and last longer.  Utilities have generous lighting conversion incentives in place.

This facility’s energy intensity picked up substantially in October, as their shelling operations commenced.  Their intense energy usage occurs mostly outside the utility’s peak rate period.  Even so, this business could use Energy Analytics to combine energy supply and pricing strategies, which would dramatically re-shape their Energy DNA, and turn the threat of expensive utility energy prices into an advantage.  Our next example provides a case in point.
