GreenUp allows you to support the development and operation of renewable energy resources in New England, such as wind, small hydro, solar, biomass, fuel cells using a renewable fuel, and landfill methane gas. You can participate in GreenUp without switching from the Standard Offer or Default Service that you receive currently from Massachusetts Electric (“National Grid”). National Grid will continue to sell and deliver your electricity to you under its Standard Offer Service or Default Service. If you choose to participate in GreenUp, you will continue to receive one electricity bill from National Grid and your GreenUp payments will be included on your bill.
GreenUp is facilitated by a new accounting system in New England that tracks the attributes of all electricity generated in New England, including the renewable energy attributes of such electricity. These renewable energy attributes are measured at the same time that the electricity is generated, and are documented in the form of certificates that may be bought and sold separately from the associated electricity supply. Your GreenUp supplier purchases certificates documenting the appropriate renewable energy attributes from the renewable energy generators on your behalf and uses the certificates to prove that, for the period relevant to the product claims it is making, your GreenUp supplier has purchased the sole rights to the claimed attributes in an amount sufficient to meet the product claims made to its customers. The accounting system ensures that the renewable energy attributes represented by the certificates are not double-counted.
As your electricity supplier, National Grid currently purchases, or makes payments equal to, sufficient certificates to meet its legal requirements under Massachusetts renewable energy laws. In 2003, Massachusetts energy laws require that one percent (1%) of your electricity supply have renewable energy characteristics as a result of National Grid’s certificate purchases, increasing to four percent (4%) in 2009. GreenUp allows you to purchase additional renewable energy certificates from a GreenUp supplier to match up to 100% of your electricity supply. Under the program, your GreenUp supplier’s purchases of certificates and sales of those certificates to you are recorded in a separate account managed by National Grid. By participating in GreenUp, you are supporting the increase of renewable energy resource contributions to the power grid and the development and generation of renewable energy resources in New England. You are also contributing to the demand for more energy from these renewable energy resources being added to the system mix for New England.
Your GreenUp supplier will send you a quarterly environmental disclosure statement that reflects your GreenUp purchases. You should be aware that the output of renewable energy generators varies over the course of a year. For example, small hydro generation occurs mostly during the spring thaw and rain season, wind generation during the winter season, and solar generation during the summer season. To account for these fluctuations, the environmental disclosure statement is based on the average of the renewable energy production and the renewable energy supplier’s GreenUp purchases over a rolling twelve-month period. Renewable energy generation meeting the definition of the Massachusetts Renewable Portfolio Standard qualifies for inclusion in GreenUp.
