DOE helps manufacturers find millions in hidden energy savings

Manufacturing plants are ripe for energy improvements, but company efforts can stall without a proper analysis of facilities to figure out where best to focus.

For the last few years, the U.S. Department of Energy has helped numerous U.S. companies analyze and reduce their energy use through its Better Buildings, Better Plants program.

"We only have so many resources to do these analyses," said Al Hildreth, energy manager at General Motors, a Better Plants partner. "And this is an extra set of resources to identify additional opportunities."

Every company that joins Better Plants makes a voluntary pledge to reduce its energy intensity by 25 percent over 10 years.

When it launched the program in 2010, DOE started with some of the industrial firms it had previously worked with. "We turned to a lot of those companies we had existing relationships with," Defontaine said.

Since then, other companies have joined, either approaching DOE on their own or finding out about the program through DOE outreach. The program recently added its 118th company partner, International Paper.

All together, 1,400 manufacturing facilities -- representing 6 percent of the U.S.’s energy footprint -- are now involved in Better Plants, said Andre Defontaine, project manager for the program.

In 2012, partner companies achieved an average energy-intensity improvement of 3.15 percent, putting them ahead of the annual improvement needed to just meet the 25 percent goal, which is 2.5 percent per year.

A major component of working toward the 25 percent goal is for companies to determine their baseline energy intensity and track and report annual changes.

In turn, the DOE helps companies set up systems for tracking energy use data and metrics, analyze data, set baselines and create plans. Companies also gain access to software tools and other technical resources.

"The first thing that companies need and where we invest most of our efforts is helping them get their arms around the metrics," Defontaine said. "Some companies do join the program with a tracking system in place. Many others aren't tracking energy efficiency because they haven't had a real need to before."
