|
|
BE IT ENACTED BY THE LEGISLATURE OF THE STATE OF TEXAS: |
|
|
SECTION 1. Section 35.151, Utilities Code, is amended to |
|
|
read as follows: |
|
|
Sec. 35.151. ELECTRIC ENERGY STORAGE. This subchapter |
|
|
applies only to the ownership or operation of electric energy |
|
|
storage equipment or facilities in the ERCOT power region that are |
|
|
intended to: |
|
|
(1) provide energy or ancillary services at wholesale, |
|
|
including electric energy storage equipment or facilities listed on |
|
|
a power generation company's registration with the commission or, |
|
|
for an exempt wholesale generator, on the generator's registration |
|
|
with the Federal Energy Regulatory Commission; or |
|
|
(2) provide reliable delivery of electric energy to |
|
|
retail customers. |
|
|
SECTION 2. Subchapter E, Chapter 35, Utilities Code, is |
|
|
amended by adding Section 35.153 to read as follows: |
|
|
Sec. 35.153. CONTRACTS FOR ELECTRIC ENERGY STORAGE FOR |
|
|
RELIABILITY SERVICES. (a) A transmission and distribution |
|
|
utility, with the approval of the commission, may contract with the |
|
|
owner or operator of an electric energy storage facility to provide |
|
|
electric energy from an electric energy storage facility to ensure |
|
|
reliable service to retail customers. |
|
|
(b) The commission may not authorize ownership of an |
|
|
electric energy storage facility by a transmission and distribution |
|
|
utility. |
|
|
(c) Before entering into a contract under Subsection (a), |
|
|
the transmission and distribution utility must issue a request for |
|
|
proposals for use of an electric energy storage facility to meet the |
|
|
utility's reliability needs. |
|
|
(d) A transmission and distribution utility may enter into a |
|
|
contract under Subsection (a) only if use of an electric energy |
|
|
storage facility is more cost-effective than construction or |
|
|
modification of traditional distribution facilities. |
|
|
(e) A transmission and distribution utility may not enter |
|
|
into a contract under Subsection (a) that reserves an amount of |
|
|
capacity exceeding the amount of capacity required to ensure |
|
|
reliable service to the utility's retail customers. |
|
|
(f) An owner or operator of an electric energy storage |
|
|
facility subject to a contract under Subsection (a) may sell |
|
|
electric energy or ancillary services through use of the facility |
|
|
only to the extent that the owner or operator reserves capacity as |
|
|
required by the contract. |
|
|
(g) An owner or operator of an electric energy storage |
|
|
facility subject to a contract under Subsection (a) may not |
|
|
discharge the facility for reliability purposes unless directed by |
|
|
the transmission and distribution utility. |
|
|
(h) A contract under Subsection (a) must require an owner or |
|
|
operator of an electric energy storage facility to reimburse a |
|
|
transportation and distribution utility for the cost of |
|
|
administrative penalties assessed against the utility for a |
|
|
violation caused by the facility's failure to meet the requirements |
|
|
of the agreement. |
|
|
(i) In establishing the rates of a transmission and |
|
|
distribution utility, a regulatory authority shall review a |
|
|
contract between the utility and an owner or operator of an electric |
|
|
energy storage facility under Subsection (a). The utility has the |
|
|
burden of proof to establish that the costs of the contract are |
|
|
reasonable and necessary. The regulatory authority may authorize a |
|
|
transmission and distribution utility to earn a reasonable return |
|
|
on the present value of future payments required under the |
|
|
contract. |
|
|
(j) The total amount of electric energy storage capacity |
|
|
reserved by contracts under Subsection (a) may not exceed 40 |
|
|
megawatts. The commission shall by rule establish the maximum |
|
|
amount of electric energy storage capacity allotted to each |
|
|
transmission and distribution utility. |
|
|
(k) The commission shall adopt rules as necessary to |
|
|
implement this section and establish criteria for approving |
|
|
contracts under Subsection (a). |
|
|
SECTION 3. The Public Utility Commission of Texas shall |
|
|
adopt rules required by Section 35.153, Utilities Code, as added by |
|
|
this Act, as soon as practicable after the effective date of this |
|
|
Act. |
|
|
SECTION 4. This Act takes effect September 1, 2019. |
