Conservation Voltage Regulation (CVR)
CVR, while previously piloted at many utilities, has had limited success due to the lack of a real time feedback loop. This shortcoming prevented the utilities from reducing the voltage to an optimum level to maximize power savings. Without a dynamic feedback loop that incorporates the end-point data, utilities have to allow for additional safety margin to ensure compliance with regulations and protect their customers from voltage sags. Power Tagging’s unique approach maximizes savings in any given ambient condition, in real time. The net result provides improved savings over other approaches.
New Load Profiles, New Challenges
One of the biggest problems facing utilities today is the need for additional generation to offset increased demand. As new demand is placed on the aging electrical infrastructure, new devices and classes of load profiles will create a dynamic and variable distribution grid. The addition of electric vehicles, flat panel TVs, air conditioning loads and simple population growth will all increase electricity demand significantly as well as create new peak load patterns. Utilities are looking at various options, from demand side management to building more generation as ways of offsetting the peak demand. Most of these involve changing customer behavior and/or making large capital expenditures.
The Power Tagging Solution
There are ways to reduce demand on the electrical system without inconveniencing customers and without large capital expenditures. Power Tagging CVR is the utility-preferred way. Utilities can operate in the lower 5% band of voltage achieving up to 5% energy savings, enabling lower carbon footprints and reduced costs. In addition, this power saving can also be used as buffered peak offset, in essence, adding energy where rapid peak relief is needed. In addition, Power Tagging CVR lays the foundation to deploy additional applications like Grid Mapping, DSM, Electric Vehicle Management and others.
