11 Solar electricity in bulk Maine PUBLIC UTILITIES COMMISSION Rule: Chapter 313, section E(5) Provides the framework for shared net metering, for up to 10 accounts. 1. Ownership Interest. Shared ownership customers must have a legally enforceable ownership interest or legally enforceable rights and obligations in the eligible facility under which the customers have joint responsibility for the costs of the shared ownership facility and have the rights to the benefits of the output of the shared ownership facility in proportion to the cost responsibilities. 2. Contact Person. Shared ownership customers must designate a single contact person to be responsible for all communications with the transmission and distribution utility regarding the shared ownership net energy billing arrangement. The contact person shall promptly inform the transmission and distribution utility of any material changes to the joint ownership interests or arrangements of the shared ownership customers, including any changes in the meters or accounts subject to net energy billing. 3. Application. Shared ownership customers must submit to the transmission and distribution utility an application

12 Group net metering Up to nine (9) accounts Solar photovoltaic (PV) array Solar electricity fed through the Power grid to electricity users. DC/AC inverters + solar production meter Credits determined by percentage share of production. Utility applies these credits to members respective utility bills.

13 Community solar farm Pair a group of dispersed buildings with a central solar power plant, all of which are interconnected through the electrical grid (or microgrid) + solar panels

14 We did it! At 13:24 0ctober 19, 2014 I turned on the power for the first Maine Community Solar Farm. --Russ Florenz

15 Notes Co-operation with utility is crucial. Suitable location. Structure Investor/PPA, or direct utilization of 30% F.T.C. by respective members. Much simpler to allow each member to monetize the federal 30% tax credit directly: Residences use the Renewable Energy Tax Credit. Businesses use the Investment Tax Credit
