This amendment is the minority report of the committee, and it replaces the bill. It 
does the following regarding net energy billing: 
1. It allows an eligible customer to elect net energy billing until December 31, 2017, 
after which time no new net energy billing aITangements may be allowed; 
2. It allows net energy billing arrangements entered into prior to December 31, 2017 
to remain in effect until December 31, 2032; 
3. It prohibits a transmission and distribution utility from requiring a customer to 
meter the gross output of an eligible facility in order to participate in net energy billing; 
and 
4. It limits to 50 the number of eligible customers that may paiiicipate in a single

The amendment establishes a market-based crediting system for energy generated by 
eligible facilities. It requires the Public Utilities Commission to adopt rules to allow an 
eligible customer to receive a monetaiy credit for energy generated by an eligible facility

7 
number of eligible customers that may paiiicipate in a single shared interest in an eligible 
facility, or the number of meters associated with a single shared interest, is limited to 50. 
The amendment exempts a transmission and distribution utility located in an area 
administered by the independent system administrator for northern Maine, or any 
successor of the independent system administrator for n01ihern Maine, from using this 
crediting system until the Public Utilities Commission dete1mines the utility's billing 
system can perfmm the necessaiy functions to implement the system. It requires the

system is modified to allow a market-based crediting system. 
It requires the Public Utilities Commission to procure, to the maximum extent 
possible, 20 megawatts of large-scale community solar distributed generation resources. 
It requires that the contract rate be calculated annually and that no contract may be for 
more than 6¢ per kilowatt-hour or the average wholesale electricity rate over the 
preceding 12 months, whichever is less. 
Lastly, it requires the Public Utilities Commission to conduct an analysis of the costs 
and benefits to ratepayers for both net energy billing and the market-based crediting 
system in an adjudicatory proceeding and to report those findings to the joint standing 
committee of the Legislature having jurisdiction over utilities and energy matters no later
