*Renewable Energy Certificate (REC): A REC represents the environmental benefits of 1 megawatt hour (MWh) of electricity generated by a renewable energy resource. Your REC purchase supports renewable electricity production in the region of generation. For every unit of renewable electricity generated, an equivalent amount of RECs is produced by purchasing and pairing RECs with your electricity service. You are using and receiving the benefits of that renewable electricity. Renewable energy certificates are not sold more than once or claimed by more than one party. 


The 31% or 81% of RECs paired with your electricity complements, rather than includes, the 19% state-minimum Renewable Portfolio Standard (RPS) for Illinois as listed at to achieve the Total Renewable Incentive marketed above. Please refer to the Terms and Conditions located on the enrollment form or contact Energy Harbor at 1-800-292-9284 for more information.
