Extra renewable energy is in reference to the Rhode Island Renewable Energy Standard (RES), which sets a minimum amount of renewable energy that must be included in all electricity supplies, regardless of whether it is provided by the utility, National Grid, or a competitive supplier. In 2022, the RES will require 19% renewable energy. For example, if the standard product includes 10% additional renewable energy, the total renewable energy will be 19%+10%=29%.
