System Impact Analysis of Carbon Capture Loads on Rural Electric Distribution Systems

In an effort to reduce carbon emissions, carbon capture systems are being implemented in agriculture related industries across Iowa. This paper presents a recent distribution system impact study conducted for a rural electric cooperative to accommodate the pumping of methane gas collected from hog confinement sewage lagoons. The analysis of the distribution system considered conductor and equipment capacity, voltage drop, power quality and motor starting impacts and protective device evaluations. Upon implementation of the study recommendations the distribution system will be able to support the new loads and allow for the capture of methane previously dispersed into the atmosphere.
