(a) During the calendar year commencing January 1, 2014, and continuing each calendar year thereafter, if alternative compliance payments pursuant to subsection (h) of § 16-244c or subsection (k) of § 16-245 are made for failure to meet the renewable portfolio standards, there shall be a presumption for the calendar year the alternative compliance payments are made that there is an insufficient supply of Class I renewable energy sources, as defined in § 16-1, for electric suppliers or electric distribution companies to comply with the requirements of § 16-245a.

(b) In the event there is a presumption of insufficient supply of Class I renewable energy sources pursuant to subsection (a) of this section for the calendar year the alternative compliance payments are made, the Commissioner of Energy and Environmental Protection may determine whether such payments resulted from a material shortage of Class I renewable energy sources. In making this determination, the commissioner shall consider whether such payments resulted from intentional or negligent action by an electric supplier or electric distribution company not to purchase renewable energy credits available in the New England Power Pool Generation Information System market.

(c) In the event there is such a presumption pursuant to subsection (a) of this section and the commissioner finds that the alternative compliance payments were due to a material shortage of Class I renewable energy sources pursuant to subsection (b) of this section, the commissioner shall determine the adequacy, or potential adequacy, of Class I renewable energy sources to meet the succeeding years’ renewable portfolio standard. In making this determination, the commissioner may consider (1) future cost and availability of certificates issued by the New England Power Pool Generation Information System based on the status of projects under development in the region, (2) future requirements of certificates issued by the New England Power Pool Generation Information System in other states, and (3) the projected compliance costs of Class I renewable energy sources.

(d) In the event there is such a presumption pursuant to subsection (a) of this section and the commissioner finds a material shortage of Class I renewable energy sources pursuant to subsection (b) of this section, and in addition to determining the adequacy pursuant to subsection (c) of this section, the commissioner shall, in consultation with the procurement manager identified in subsection (l) of § 16-2, the Office of Consumer Counsel and the Attorney General, solicit proposals from providers of Class I renewable energy sources, as defined in § 16-1, operational as of the date that such solicitation is issued. If the commissioner, in consultation with the procurement manager identified in subsection (l) of § 16-2, finds such proposals to be in the interest of ratepayers including, but not limited to, the delivered price of such sources, and consistent with the requirements to reduce greenhouse gas emissions in accordance with § 22a-200a, and in accordance with the policy goals outlined in the Comprehensive Energy Strategy, adopted pursuant to § 16a-3d, the commissioner, in consultation with the procurement manager identified in subsection (l) of § 16-2, may select proposals from such sources to meet up to the amount necessary to ensure an adequate incremental supply of Class I renewable energy sources to rectify any projected shortage of Class I renewable energy supply identified pursuant to subsection (c) of this section. The commissioner shall direct the electric distribution companies to enter into power purchase agreements for energy, capacity and environmental attributes, or any combination thereof, from such selected proposals for periods of not more than ten years. Certificates issued by the New England Power Pool Generation Information System for any Class I renewable energy sources procured under this section shall be sold in the New England Power Pool Generation Information System renewable energy credit market to be used by any electric supplier or electric distribution company to meet the requirements of § 16-245a. Any such agreement shall be subject to review and approval by the Public Utilities Regulatory Authority, which review shall commence upon the filing of the signed power purchase agreement with the authority. The authority shall issue a decision on such agreement not later than thirty days after such filing. In the event the authority does not issue a decision within thirty days after such agreement is filed with the authority, the agreement shall be deemed approved. The net costs of any such agreement, including costs incurred by the electric distribution companies under the agreement and reasonable costs incurred by the electric distribution companies in connection with the agreement, shall be recovered through a fully reconciling component of electric rates for all customers of electric distribution companies.

(e) Notwithstanding subdivision (1) of subsection (b) of § 16-245a, in the event that (1) for any calendar year commencing on or after January 1, 2014, there is such a presumption pursuant to subsection (a) of this section, (2) the commissioner finds material shortage of Class I renewable energy sources pursuant to subsection (b) of this section, (3) there is a determination of inadequacy pursuant to subsection (c) of this section, and (4) any contracts for Class I renewable energy sources approved by the Public Utilities Regulatory Authority pursuant to subsection (d) of this section yield an amount of Class I renewable energy sources that is insufficient to rectify any projected shortage pursuant to subsection (c) of this section, then commencing on or after January 1, 2016, the commissioner may allow not more than one percentage point of the Class I renewable portfolio standards established pursuant to § 16-245a effective for the succeeding and subsequent calendar years to be satisfied by large-scale hydropower procured pursuant to § 16a-3g. The requirements applicable to electric suppliers and electric distribution companies pursuant to § 16-245a shall consequently be reduced by not more than one percentage point in proportion to the commissioner’s action, provided (A) the commissioner shall not allow a total of more than five percentage points of the Class I renewable portfolio standard to be met by large-scale hydropower by December 31, 2020, and (B) no such large-scale hydropower shall be eligible to trade in the New England Power Pool Generation Information System renewable energy credit market.
