Westborough, Massachusetts [RenewableEnergyAccess.com] Evolution Markets LLC completed an auction of renewable energy certificates (RECs) for the Massachusetts Technology Collaborative (MTC), a public economic-development agency that manages the state’s Renewable Energy Trust, for an average price of $53.10. The certificates are from the Ameresco Chicopee landfill-gas-to-energy facility, which have been approved by the Massachusetts Division of Energy Resources (DOER) as an eligible source under the Massachusetts Renewable Portfolio Standard (RPS). The RECs sold in the auction can be used for compliance under Massachusetts’ RPS, or for Massachusetts voluntary green choice programs. The RPS mandates that companies selling electricity on the retail level in the state must “retire” a quantity of qualified RECs equivalent to a percentage of the total number of megawatt hours they sell. For 2005, that percentage is 2.0%. In addition, through voluntary choice programs, a growing number of Massachusetts consumers are choosing to pay a bit more on their electricity bill to support renewable projects.
