The standard offer provider designated pursuant to Chapter 301 of the Commission's rules to serve residential customers within the ISO-NE control area shall purchase any electricity available from any eligible generator located in the transmission and distribution service territory in which the standard offer provider is obligated to provide service, if requested to do so by the entity who own or controls the eligible generator. Requests for a standard offer provider to purchase electricity pursuant to this subsection shall be made through the transmission and distribution utility charged with administering the transaction between the eligible generator and the standard offer provider.B.Purchase Price. The standard offer provider shall purchase the energy from an eligible generator at the ISO-NE real-time nodal clearing price for the node on which the generator is located. The purchase price under this subsection shall be reduced for any incremental ISO-NE system administrative costs charged to the purchasing standard offer provider as a result of the requirements of this Chapter. The Commission by order may change the applicable purchase price upon a finding that another price would result in the transaction being financially neutral to the standard offer provider consistent with the purposes of this Chapter.C.Multiple Providers. If there are multiple standard offer providers serving residential customers within a transmission and distribution utility service territory, the purchase obligation shall be apportioned according to each provider's share of the standard offer load obligation.D.Northern Maine. The purchase requirements of this Chapter shall become applicable to entities in northern Maine upon a finding by the Commission that the market design in northern Maine will accommodate the purchase of electricity from eligible generators by a standard offer provider in a manner that is financially neutral to the standard offer provider. In the event the Commission makes the requisite finding, it shall determine the appropriate means of establishing the purchase price.65- 407 C.M.R. ch. 315, § 3
