EPB Working with Department of Energy to Improve Smart Grid
By
on
EPB estimates local businesses have saved approximately $50 million by reducing lost productivity due to power outages by 60 percent over the past two years. Those figures are impressive but Oak Ridge National Laboratory (ORNL) will be working with EPB to raise them even higher.
The Times Free Press recently reported that ORNL will send engineers to Chattanooga to optimize the use of data from the EPB smart grid. The goal will be to increase efficiency even further and to use their discoveries to help other U.S. electric utilities.
"We have to have a more reliable electric system," DePriest said after signing an agreement Monday to work with the Oak Ridge lab on electric grid improvements. "Electricity is essential to our modern way of life and we have to figure out ways to use all the data we are gathering in a quicker and more usable manner."
EPB's smart grid now gathers data in 15 minute increments whereas many utilities that have less sophisticated capabilities only collect data once or twice a month. EPB's system quickly discovers problems that can balloon into costly mistakes if not detected early.
As more people use solar, wind, or geothermal power, providing electricity or purchasing electricity from consumers becomes more complicated.
"We need to continue to innovate and get better," said Patricia Hoffman, assistant secretary for DOE's electricity delivery and energy division. "Chattanooga has been a leader and we hope this will help us find ways to make our electric grid more efficient, more flexible and more reliable."
