Be it enacted by the People of the State of Maine as follows:
Sec. 1.  35-A MRSA §3218 is enacted to read:
§3218.  Electricity usage by data centers
1. Definitions. For the purposes of this section, unless the context otherwise indicates, 
the following terms have the following meanings.
A. "Data center" means any facility in the State that primarily contains electronic 
equipment used to process, store and transmit digital information, which may be a 
freestanding structure or a facility within a larger structure, that uses environmental 
control equipment to maintain the proper conditions for the operation of electronic 
equipment.
B. "Generation service provider" means an entity providing generation service, except 
"generation service provider" does not include an entity providing generation service 
behind the meter to a data center adjacent to the electricity generating facility.
C. "Usage maximum" means 25% of the total electricity sold by a generation service 
provider to all of the generation service provider's customers in the State in a calendar 
year.
2. Limitation on usage. A generation service provider may not in a calendar year 
provide to data centers in the State a cumulative amount of electricity that exceeds the 
usage maximum for that calendar year.
3. Usage reports. A generation service provider shall file with the commission 
quarterly reports identifying each data center for which it provides generation service, the 
amount of electricity sold to each data center that quarter and any other information related 
to the electricity consumption of the data center that the commission may require by rule. 
The report must include the total amount of electricity sold to all of the generation service 
provider's customers.
4. Violations. A generation service provider that violates this section is subject to 
administrative penalties in accordance with section 1508-A. 
5. Rules. The commission may adopt rules to implement this section. Rules adopted 
by the commission pursuant to this subsection are routine technical rules as defined in Title 
5, chapter 375, subchapter 2‑A.
SUMMARY
This bill prohibits an entity providing generation service to data centers in the State 
from providing an amount of electricity that is more than 25% of the amount of electricity 
sold to all of the entity's customers in the State in a calendar year. The prohibition does not 
apply to a generation service provider that is providing generation service behind the meter 
to a data center adjacent to the electricity generating facility. The bill requires generation 
service providers to file quarterly reports with the Public Utilities Commission, including 
information about data centers that are receiving service from the generation service 
provider. The Public Utilities Commission may adopt routine technical rules to implement 
the requirements of this legislation.
