(ii) for a system that files a complete application for a certificate of public good after December 31, 2025, if the system serves a multifamily building containing qualified rental units serving low-income tenants, as defined under 32 V.S.A. § 5404a(a)(6), generates energy that will be used on the same parcel as, or a parcel adjacent to, the parcel where the plant is located; and
(iii) for purposes of subdivisions (10) and (16), two parcels shall be adjacent if they share a property boundary or are adjacent and separated only by a river, stream, railroad line, private road, public highway, or similar intervening landform.
(17) “New renewable energy” means renewable energy capable of delivery in New England and produced by a specific and identifiable plant coming into service on or after January 1, 2010, but excluding energy generated by a hydroelectric generation plant with a capacity of 200 MW or greater.
(A) Energy from within a system of generating plants that includes renewable energy shall not constitute new renewable energy, regardless of whether the system includes specific plants that came or come into service on or after January 1, 2010.
(B) Except as provided in subdivision 8005(c)(3) of this title, “new renewable energy” also includes the additional energy from an existing renewable energy plant retrofitted with advanced technologies or otherwise operated, modified, or expanded to increase the kWh output of the plant in excess of a historical baseline established by calculating the average output of that plant for the 10-year period that ended January 1, 2010. If the production of new renewable energy through changes in operations, modification, or expansion involves combustion of the resource, the system also must result in an incrementally higher level of energy conversion efficiency or significantly reduced emissions.
(18) “Plant” means an independent technical facility that generates electricity from renewable energy. A group of facilities, such as wind turbines, shall be considered one plant if the group is part of the same project and uses common equipment and infrastructure such as roads, control facilities, and connections to the electric grid. Common ownership, contiguity in time of construction, and proximity of facilities to each other shall be relevant to determining whether a group of facilities is part of the same project.
