NARR Homepage

NARR is the North American Renewables Registry. The primary role of the registry is to provide REC origination for clean generation facilities located in states and provinces not covered by the five current regional systems: NEPOOL (GIS), PJM (GATS), ERCOT, MISO (M-RETS), and WREGIS. The purpose is to complement the existing market systems and provide complete North American coverage for renewable energy markets. NARR is operated by APX, Inc.
