| (a) Application. This section applies to transmission
and distribution utilities, excluding river authorities; an electric
utility subject to Public Utility Regulatory Act (PURA) Chapter 39,
Subchapter L; distributed renewable generation owners as defined in §25.217
of this title (relating to Distributed Renewable Generation); and
the entity responsible for settlement.
(b) Metering.
(1) Upon request by a customer that has, or is in the
process of installing distributed renewable generation with a capacity
of less than 50 kilowatts (kW) on the retail electric customer's side
of the meter and that desires to measure the generation's out-flow
production, an electric utility shall provide metering at the point
of common coupling using one or two meters that separately measure
both the customer's electricity consumption from the distribution
network and the out-flow that is delivered from the customer's side
of the meter to the distribution network and separately report each
metered value to the transmission and distribution utility. The two
metered values shall be separately accounted for by the entity responsible
for settlement.
(2) Upon request by a retail electric customer that
has, or is in the process of installing distributed renewable generation
with a capacity equal to or greater than 50 kW up to 2,000 kW on the
retail electric customer's side of the meter, an electric utility
shall provide one or two interval data recorders at the point of common
coupling that separately measure both the customer's electricity consumption
from the distribution network and the out-flow that is delivered from
the retail electric customer's side of the meter to the distribution
network and separately report each metered value to the transmission
and distribution utility. The two metered values shall be separately
accounted for by the entity responsible for settlement.
(3) Upon request by a retail electric customer that
has, or is in the process of installing distributed renewable generation
with a capacity of less than 50 kW on the retail electric customer's
side of the meter and that does not desire to measure the generation's
out-flow production, an electric utility shall provide metering in
accordance with paragraph (1) of this subsection or, at the electric
utility's option, install a meter that measures the customer's electricity
consumption from the distribution network but does not measure the
out-flow that is delivered from the retail electric customer's side
of the meter to the distribution network. Unless an existing distributed
renewable generation owner requests to have the existing meter replaced,
the electric utility may, at its option and expense, replace an existing
distributed renewable generation owner's meter with a meter of a type
specified in this rule.
(4) Pursuant to the applicable schedule in its tariff,
an electric utility shall charge for the customer's electricity consumption
from the distribution network as measured by the metering installed
pursuant to paragraph (1), (2) or (3) of this subsection.
(5) An electric utility shall not provide metering
for purposes of PURA §39.914(d) and PURA §39.916(f), that
is inconsistent with paragraph (1), (2) or (3) of this subsection,
unless ordered by the commission.
(6) The distributed renewable generation owner shall
pay any significant differential cost of the metering.
(7) Electric utilities shall file tariffs for metering
under this section within 60 days of its effective date.
(8) Distributed renewable generation owners may begin
selling out-flow at any time. Electric utilities are required to comply
with paragraphs (1), (2) and (3) of this subsection, as they relate
to reporting the two metered values. The entity responsible for settlement
is required to accept the meter data provided pursuant to paragraph
(1), (2) or (3) of this subsection.
(9) The entity responsible for settlement shall have
a process for settlement of electricity consumption and out-flow that
reflects time of generation.
(c) Metering Provisions Specific to an Electric Utility
Subject to PURA Chapter 39, Subchapter L.
(1) This subsection applies to an electric utility
subject to PURA Chapter 39, Subchapter L.
(2) An electric utility shall provide the additional
option of interconnection through a single meter that runs forward
and backward for a customer that is either:
(A) an apartment house occupied by low-income elderly
tenants that qualifies for master metering under Texas Utilities Code §184.012(b)
and the distributed renewable generation is reasonably expected to
generate not less than 50 percent of the apartment house's annual
electricity use; or
(B) has a qualifying facility with a design capacity
of 50 kW or less and that uses a renewable energy resource.
(3) The net metering option provided by paragraph (2)
of this subsection is available only if the distributed renewable
generation or qualifying facility is rated to produce an amount of
electricity that is less than or equal to:
(A) the customer's estimated annual kilowatt-hour consumption
for a new apartment house or qualifying facility; or
(B) the amount of electricity the customer consumed
in the year before installation of the distributed renewable generation
or qualifying facility.
(4) Measured net consumption shall be billed under
the electric utility's standard tariff schedule applicable to the
customer. Measured net production shall be purchased in accordance
with §25.217 of this title.
(5) The electric utility shall credit the payments
to the customer's monthly electric service bill, and specify in the
bill the amount of non-firm energy purchased in kilowatt hours. If
the payment for non-firm energy supplied to the electric utility exceeds
the total of the owner's monthly electric service bill, a credit balance
of not more than $50 shall be carried forward to the owner's next
monthly bill. The electric utility shall refund to the customer a
credit balance that is not carried forward, or the portion of a credit
balance that exceeds $50, if the credit balance is carried forward.
(6) An electric utility shall install, maintain, and
retain ownership of the meter(s) and metering equipment installed
for purposes of this subsection and may install load research metering
equipment on the premises of the owner, at no expense to the owner.
(7) At the request of an electric utility, the customer
shall:
(A) provide and install a meter socket, a metering
cabinet, or both a socket and cabinet at a location designated by
the electric utility on the premises of the owner; and
(B) provide, at no expense to the electric utility,
a suitable location for the electric utility to install meters and
equipment associated with billing and load research.
