If a project uses no fossil fuel, the marginal greenhouse gas emissions are defined as zero. (15) The term marginal fossil fuel use means the fossil fuel combusted to produce energy by the project, measured in metric tons per year, minus any existing fossil combustion, measured in metric tons per year, within the same system that is determined by the Administrator of the Environmental Protection Agency in consultation with the Secretary of Energy and Administrator of the Energy Information Administration to be necessary to the production of the contracted energy generation and would have been consumed regardless of the addition of the contracted energy generation.
