|BILL AS INTRODUCED||2007-2008|
Introduced by Senator Snelling of Chittenden District
Subject: Public service; net metering
Statement of purpose: This bill proposes to revise the net metering law, raising the existing cap on nonfarm net metering systems to 150 kW capacity; expanding the program to include micro-combined heat and power systems of 20 kW or fewer, even if they do not employ a renewable energy source; increasing the maximum size of “farm system” from 150 to 250 kW; allowing use of “group net metering systems” subject to various provisions controlling use of farm systems; limiting net metering systems to customers within the service area of the same electric company; allowing multiple buildings of a municipality to qualify; and granting the public service board the authority to allow noncontiguous groups, if to do so promotes the general good. It also increases a company’s system cap regarding how much net‑metered power it must accept, from one percent up to two percent of the company’s peak demand in 1996. It repeals the provision that allows an electric company to receive from farm systems any tradable renewable credits for which the farm system is eligible. It provides that the public service board annually may allow 10 non‑farm systems that are larger than 150 kW but smaller than 250 kW.
AN ACT RELATING TO EXPANDING THE SCOPE OF NET METERING
It is hereby enacted by the General Assembly of the State of Vermont:
Sec. 1. 30 V.S.A. § 219a is amended to read:
§ 219a. SELF‑GENERATION AND NET METERING
(a) As used in this section:
(1) “Customer” means a retail electric consumer who uses a net metering system.
(2) “Net metering” means measuring the difference between the electricity supplied to a customer and the electricity fed back by a net metering system during the customer’s billing period:
(A) using a single, nondemand meter or such other meter that would otherwise be applicable to the customer’s usage but for the use of net metering; or
(B) on farm or group systems, using multiple meters as specified in this chapter. The calculation will be made by converting all meters to a nondemand, nontime‑of‑day meter, and equalizing them to the tariffed kilowatt‑hour rate.
(3) “Net metering system” means a facility for generation of electricity that:
of no more than
15 150 kilowatts (AC) capacity, or is a farm
* * *
(E)(i) employs a renewable energy source as defined in subdivision 8002(2) of this title; or
(ii) is a qualified micro‑combined heat and power system of 20 kilowatts or fewer that meets the definition of combined heat and power in 10 V.S.A. § 6523(b) and may use any fuel source that meets air quality standards.
“Farm system” means a facility of no more than
150 250 kilowatts
(AC) output capacity, except as provided in subdivision (k)(5) of this section,
that generates electric energy on a farm operated by a person principally
engaged in the business of farming, as that term is defined in Regulation 1.175‑3
of the Internal Revenue Code of 1986, from the anaerobic digestion of
agricultural products, byproducts, or wastes, or other renewable sources as
defined in subdivision (3)(E) of this subsection, intended to offset the meters
designated under subdivision (g)(1)(A) of this section on the farm or has entered
into a contract as specified in subsection (k) of this section.
(b) A customer shall pay the same rates, fees, or other payments and be subject to the same conditions and requirements as all other purchasers from the electric company in the same rate‑class, except as provided for in this section, and except for appropriate and necessary conditions approved by the board for the safety and reliability of the electric distribution system.
* * *
(f) Consistent with the other provisions of this title, electric energy measurement for net metering farm or group net metering systems shall be calculated in the following manner:
(1) Net metering customers that are farm or group net metering systems may credit on‑site generation against all meters designated to the farm system or group net metering system under subdivision (g)(1)(A) of this section.
(2) Electric energy measurement for farm or group net metering systems shall be calculated by subtracting total usage of all meters included in the farm or group net metering system from total generation by the farm or group net metering system. If the electricity generated by the farm or group net metering system is less than the total usage of all meters included in the farm or group net metering system during the billing period, the farm or group net metering system shall be credited for any accumulated kilowatt‑hour credit and then billed for the net electricity supplied by the electric company, in accordance with the procedures in subsection (g) of this section.
(3) If electricity generated by the farm or group net metering system exceeds the electricity supplied by the electric company:
(A) The farm or group net metering system shall be billed for the appropriate charges for each meter for that month, in accordance with subsection (b) of this section.
(B) Excess kilowatt‑hours generated during the billing period shall be added to the accumulated balance with this kilowatt‑hour credit appearing on the bill for the following billing period.
(C) Any accumulated kilowatt‑hour credits shall be used within 12 months or shall revert to the electric company without any compensation to the farm or group net metering system. Power reverting to the electric company under this subdivision (3) shall be considered SPEED resources under section 8005 of this title.
In addition to any other requirements of section 248 of this title and this
section and board rules thereunder, before a
net metering farm or
group net metering system including more than one
meter may be formed and served by an electric company, the proposed net
metering farm or group net metering system
shall file with the board, with copies to the department and the serving
electric company, the following information:
the meters to be included in the farm or group net metering system,
which shall be associated with the
farm buildings and residences owned
or occupied by the person operating the farm or group net metering system,
or the person’s family or farm employees, or other members of
the group, identified by account number and location;
(B) a method for adding and removing meters included in the farm or group net metering system;
designated person responsible for all communications from the farm or
group net metering system to the serving electric company, for
receiving and paying bills for any service provided by the serving electric
company for the farm or group net metering system,
and for receiving any other communications regarding the farm or
group net metering system
net metering; and
(D) a binding process for the resolution of any disputes within the farm or group net metering system relating to net metering that does not rely on the serving electric company, the board, or the department.
or group net metering system shall, at all times, maintain a
written designation to the serving electric company of a person who shall be
the sole person authorized to receive and pay bills for any service provided by
the serving electric company, and
for receiving to receive any
other communications regarding the farm system, the group net metering
system, or net metering.
The serving utility shall implement appropriate changes to the farm
or group net metering system within 30 days after receiving
written notification from the designated person. However, written notification
of a change in the person designated under subdivision (2) of this subsection
shall be effective upon receipt by the serving utility. The serving utility
shall not be liable for action based on such notification, but shall make any
necessary corrections and bill adjustments to implement revised notifications.
(4) Pursuant to subsection 231(a) of this title, after such notice and opportunity for hearing as the board may require, the board may revoke a certificate of public good issued to a farm or group net metering system.
(5) A group net metering system may consist only of customers that are located within the service area of the same electric company. Various buildings owned by a municipality may constitute a group net metering system. Upon determining that to do so would promote the general good, the board shall permit a noncontiguous group of net metering customers to become a group net metering system.
(h)(1) An electric company:
Shall make net metering available to any customer using a net metering system,
group net metering system, or farm system on a first‑come, first‑served
basis until the cumulative output capacity of net metering systems equals
2.0 percent of the distribution company’s peak demand during 1996; or
the peak demand during the most recent full calendar year, whichever is
greater. The board may raise the 1.0 2.0 percent cap. In
determining whether to raise the cap, the board shall consider the following:
(i) the costs and benefits of net metering systems already connected to the system; and
the potential costs and benefits of exceeding the cap, including potential
short- and long‑term impacts on rates, distribution system costs
and benefits, reliability and diversification costs and benefits;
(B) Shall allow net metering systems to be interconnected using a kilowatt‑hour meter capable of registering the flow of electricity in two directions or such other comparably equipped meter that would otherwise be applicable to the customer’s usage but for the use of net metering;
(C) May, at its own expense, and with the written consent of the customer, install one or more additional meters to monitor the flow of electricity in each direction;
Except as otherwise provided in this section, shall charge the customer
a minimum monthly fee that is the same as for other customers of the
electric distribution company in the same rate class, but shall not charge the
customer any additional standby, capacity, interconnection, or other fee or
(E) May require a customer to comply with generation interconnection, safety, and reliability requirements, as determined by the public service board by rule or order, and may charge reasonable fees for interconnection, establishment, special metering, meter reading, accounting, account correcting, and account maintenance of net metering arrangements of greater than 15 kilowatt (AC) capacity;
(F) May charge, if the capacity of the distribution system is insufficient for the designed generation, subject to determination by the board, a reasonable fee to cover the cost of electric company improvements necessary to distribute power;
(G) May require that all meters included within a farm or group net metering system be read on the same billing cycle;
May book and defer, with carrying costs, additional incremental costs, to the
extent that such costs are not recovered through charges, authorized in
subdivisions (D), (E), and (F) of this subdivision (1), directly related to
implementing net metering of greater than 15 kilowatt (AC) capacity
Shall receive from a farm system, which is designed to produce less energy than
the total annual load of the meters identified in subdivision (g)(1)(A) of this
section, any tradeable renewable credits for which the farm system
is eligible. All other farm systems shall retain any tradeable renewable
credits for which the farm is eligible;.
(2) All such requirements shall be pursuant to and governed by a tariff approved by the board and any applicable board rule, which tariffs and rules shall be designed in a manner reasonably likely to facilitate net metering.
* * *
Notwithstanding the provisions of this section that define a net metering
system as being of no more than
15 150 kilowatts (AC) capacity,
the board may allow net metering for up to ten systems per year for customers
that produce more than 15 150 kilowatts (AC) capacity, but do not
produce more than 150 250 kilowatts of power and are not farm
(k) Notwithstanding the provisions of subsections (f) and (g) of this section, an electric company may contract to purchase all or a portion of the output products from a farm or group net metering system, provided:
(1) the farm or group net metering system obtains a certificate of public good under the terms of subsections (c) and (d) of this section;
(2) any contracted power shall be subject to the limitations set forth in subdivision (h)(1) of this section;
(3) any contract shall be subject to interconnection and metering requirements in subdivisions (h)(1)(C) and (i)(2) and (3) of this section;
(4) any contract may permit all or a portion of the tradeable renewable energy credits for which the farm or group net metering system is eligible to be transferred to the electric company;
the output capacity of a system may exceed
150 250 kilowatts,
(A) the contract assigns the amount of power to be net metered;
the net metered amount does not exceed
150 250 kilowatts; and
(C) only the amount assigned to net metering is assessed to the cap provided in subdivision (h)(1)(A) of this section.
