Sec. 2. 35-A MRSA §3209-A, sub-§9 is enacted to read:
9. Applicability to projects between one megawatt and 2 megawatts.
generation resource with a nameplate capacity of at least one megawatt and not more than
2 megawatts may be used for net energy billing under this section only if the requirements
of paragraph A are met.
A. On or before December 31, 2024, the proposed distributed generation resource must
reach commercial operation by the date specified in the net energy billing agreement
or by the date specified with an allowable modification to that agreement.
An entity proposing the development of a distributed generation resource that does not
meet the requirement of this subsection may petition the commission for a good-cause
exemption due to external delays outside of the entity's control, which the commission may
grant if it finds that without the external delays the entity could reasonably have been
expected to meet the requirement.
Sec. 3. 35-A MRSA §3209-B, sub-§7, as enacted by PL 2021, c. 390, §2, is
amended to read:

8. Limitation.
used for net energy billing under this section only if the distributed generation resource is
collocated with all of the distributed generation resource's net energy billing customers and
those customers are subscribed to 100% of the facility's output under this section. This
limitation does not apply to a distributed generation resource with a net energy billing
agreement that was executed on or before December 31, 2023. An amendment, revision or
reissuance of an agreement under this subsection that occurs after December 31, 2023 may
not be interpreted to affect the date on which the agreement was initially executed.
Sec. 5. 35-A MRSA §3209-C
§3209-C. Net energy billing cost recovery
The commission shall ensure that benefits of distributed generation under net energy
billing are reported and net energy billing costs are allocated in accordance with this
section. Page 3 - 131LR1471(03)
1. Definitions. As used in this section, unless the context otherwise indicates, the
following terms have the following meanings.
A. "Benefits of distributed generation under net energy billing" means all benefits
determined by the commission to be reasonably attributable to distributed generation
projects under section 3209-A and 3209-B, including but not limited to:
(1) Avoided energy and capacity costs. In determining avoided energy and
capacity costs, the commission shall use reasonable estimates of energy and
capacity market prices and account for transmission and distribution line losses.
The commission may determine different avoided costs for different time periods,
including, but not limited to, peak and off-peak periods and summer and winter
periods;
(2) Avoided transmission and distribution costs. In determining avoided
transmission and distribution costs, the commission shall use estimates of the
marginal transmission and distribution costs and may determine different avoided
costs for different time periods;
(3) Avoided fossil fuel costs. The commission shall determine avoided fossil fuel
costs based on estimated reductions in oil, gas or other fossil fuel use and estimated
market prices for these fuels;
(4) Avoided transmission and distribution line losses;
(5) Demand reduction induced price effects;
(6) Transmission and distribution plant extensions or upgrades funded by net
energy billing customers; and
(7) Any other benefits identified by the commission.
B. "Net energy billing" means net energy billing arrangements under section 3209-A
or 3209-B.
C. "Net energy billing costs" means all legitimate and verifiable costs incurred by a
transmission and distribution utility directly attributable to net energy billing. "Net
energy billing costs" does not include any costs incurred by a project sponsor as defined
in section 3209-A, subsection 1, paragraph D, a net energy billing customer or any
other entity, as determined by the commission by rule.
2. Determination of costs and benefits. The commission annually shall determine the
net energy billing costs and benefits of distributed generation under net energy billing for
the previous year.
A. When determining the benefits of distributed generation under net energy billing,
the commission shall use any available regional avoided energy supply cost study that
the commission finds to be applicable to the determination and has been developed
through a transparent process, with input from state agencies, public advocates and
utilities or energy efficiency administrators from at least 3 other states in New England.
When relevant information specific to this State is not provided in the regional study,
the commission may use the regional information in the regional study or information
from other sources supported by evidence in the commission's record. Page 4 - 131LR1471(03)
B. The commission shall allocate to each investor-owned transmission and distribution
utility its pro rata share of net energy billing costs. If the commission finds that a benefit
of distributed generation under net energy billing provides a monetized net financial
benefit to an investor-owned transmission and distribution utility that the commission
does not otherwise account for when setting rates for the utility, the net financial benefit
must be applied to offset the net energy billing costs allocated under this paragraph.
The allocation must be based on each utility's total retail kilowatt-hour energy sales to
ratepayers that pay net energy billing costs. The commission may determine the means
to be used for the allocation required under this subsection, and those means may
include the direct transfer of funds between transmission and distribution utilities.
3. Reporting of costs and benefits. The commission shall submit an annual report no
later than March 31st to the joint standing committee of the Legislature having jurisdiction
over utilities matters describing net energy billing costs and benefits of distributed
generation under net energy billing determined by the commission under subsection 2. The
report must include, but is not limited to, costs authorized to be collected by transmission
and distribution utilities in rates and benefits directly received by ratepayers. The
commission shall distinguish costs and benefits that are monetized from costs and benefits
that are not monetized. If costs or benefits are monetized, the commission shall specify the
entities to which the monetized value accrues, which may include, but are not limited to,
electricity customers, electricity supply providers and transmission and distribution
utilities.
4. Rules. The commission shall adopt rules necessary to implement this section. Rules
adopted by the commission under this subsection are routine technical rules as defined in
Title 5, chapter 375, subchapter 2-A.
Sec. 6. 35-A MRSA §3209-D
