“Advanced Conservation Voltage Reduction: A Department of Defense Perspective” by Dr. Cyrus Jabbari

The Department of Defense and the U.S. Army Installation Management Command (IMCOM) provide guidelines to military installations to actively engage in reducing energy usage, create energy efficient and energy savings plans, and when possible, look for alternative sources of energy (e.g., solar, wind). In most cases, energy savings are dependent on the replacement of older non-efficient equipment with new and more efficient devices which often require unavailable resources.

When the Fort Myer team was presented by the utility company Dominion with the concept of Conservation Voltage Reduction (CVR), Fort Myer decided to apply this research project to its power grids. The principle behind the CVR project is to reduce the voltage at the points of consumption to a safe minimum level thereby decreasing waste energy. The analysis of utility billings over a two-year period indicates a minimum annual reduction of 3% in energy consumption (measured in kilowatt hours). This cost reduction is especially significant for installations that have a high rate of electric commodity.

Although it creates additional energy savings, the MicroCVR project that reduces voltage levels further down the line and at the building levels was deemed economically not feasible to the Government due to lack of experienced operators and maintenance costs.

“Utilization of Advanced Conservation Voltage Reduction for Energy Reduction on DoD Installations” by  Mr. Bruce Ensley

The Department of Defense (DoD) continues to be the largest federal consumer of energy and needs to reduce its energy consumption. Supplying energy to DoD buildings is a significant portion of the DoD budget. Current energy conservation methods principally require changes in human behavior or require significant investment in new technology. Changing human behavior has proved challenging, oftentimes unsustainable, and requires significant increasing investments in technology development. Effecting these changes is difficult in the current fiscal environment. Conservation Voltage Reduction (CVR) is an automated system-level voltage reduction technology that optimizes voltage to continuously reduce energy consumption for devices connected to the distribution system. MicroCVR builds off the same electrical principles and effectively performs the same function at the building level but improves performance by using high-speed voltage regulation and appliance level monitoring. Combining these two technologies is an innovative, state-of-the-art approach which has not been made commercially available yet. Dominion Energy showed that the installation’s electrical distribution systems can reduce annual energy between 3-5%, work with high variation loads caused by renewable generation, improve reliability, and enhance and secure critical facility loads.
