Section 1. Section 11F of Chapter 25A is hereby amended by sticking paragraph (d) in its eternity and inserting in its place the following:

(d) Every retail electric supplier providing service under contracts executed or extended on or after January 1, 2009, shall provide a minimum percentage of kilowatt-hour sales to end-use customers in the commonwealth from Class II renewable energy generating sources. For the purposes of this section, a Class II renewable energy generating source is one that began commercial operation before December 31, 1997 and generates electricity using any of the following: (1) solar photovoltaic or solar thermal electric energy; (2) wind energy; (3) ocean thermal, wave or tidal energy; (4) fuel cells utilizing renewable fuels; (5) landfill gas; (6) energy generated by existing hydroelectric facilities, provided that such existing facility shall meet appropriate and site-specific standards that address adequate and healthy river flows, water quality standards, fish passage and protection measures and mitigation and enhancement opportunities in the impacted watershed as determined by the department in consultation with relevant state and federal agencies having oversight and jurisdiction over hydropower facilities; and provided further, that only energy from existing facilities up to 7.5 megawatts shall be considered renewable energy and no such facility shall involve pumped storage of water nor construction of any new dam or water diversion structure constructed later than January 1, 1998; (7) low emission advanced power conversion technologies using fuels such as by-products or waste from agricultural crops, food or animals, energy crops, biogas, liquid biofuel including but not limited to biodiesel, organic refuse-derived fuel, or algae; (8) marine or hydrokinetic energy as defined in section 3; or (9) geothermal energy. A facility shall not be a Class II renewable generating source unless it operates or contracts for one or more recycling programs approved by the department of environmental protection. At least 34.75 per cent of any revenue received by the facility through the sale of Massachusetts RPS–eligible renewable energy certificates shall be allocated to such recycling programs. A Class II renewable generating source may be located behind the customer meter within the ISO–NE control area provided that the output is verified by an independent verification system participating in the NEPOOL GIS accounting system and approved by the department.
