October 2010 - APX announced that it has increased functionality of multiple tracking systems. The North American Renewables Registry (NAR) is now able to accept inter-registry transfers. Renewable energy certificates (RECs) can be exported from NAR to the North Carolina Renewable Energy Tracking System (NC RET) and RECs can be imported to NAR from the Midwest Renewable Energy Tracking System (M-RETS) and NC RETS. NAR has also added functionality to track RECs eligible for the Missouri Renewable Energy Standard (RES) and established a Web site specific to using NAR for Missouri RES compliance.
