1010 BE IT ENACTED BY THE LEGISLATURE OF THE STATE OF TEXAS:
1111 SECTION 1. The heading to Section 39.159, Utilities Code,
1212 as added by Chapter 426 (S.B. 3), Acts of the 87th Legislature,
1313 Regular Session, 2021, is amended to read as follows:
1414 Sec. 39.159. POWER REGION RELIABILITY AND DISPATCHABLE
1515 GENERATION.
1616 SECTION 2. Section 39.159, Utilities Code, as added by
1717 Chapter 426 (S.B. 3), Acts of the 87th Legislature, Regular
1818 Session, 2021, is amended by adding Subsections (d), (e), and (f) to
1919 read as follows:
2020 (d) The commission shall require the independent
2121 organization certified under Section 39.151 for the ERCOT power
2222 region to consider implementing an ancillary services program to
2323 procure dispatchable reliability reserve services on a day-ahead
2424 and real-time basis to account for market uncertainty. The program
2525 to be considered may:
2626 (1) determine the quantity of services necessary based
2727 on historical variations in generation availability for each season
2828 based on a targeted reliability standard or goal, including
2929 intermittency of non-dispatchable generation facilities and forced
3030 outage rates, for dispatchable generation facilities;
3131 (2) develop criteria for resource participation that
3232 require a resource to:
3333 (A) be capable of running for at least four hours
3434 at the resource's high sustained limit or for more than four hours
3535 as the organization determines is needed;
3636 (B) be online and dispatchable not more than two
3737 hours after being called on for deployment; and
3838 (C) have the dispatchable flexibility to address
3939 inter-hour operational challenges; and
4040 (3) reduce the amount of reliability unit commitment
4141 by the amount of dispatchable reliability reserve services procured
4242 under this section.
4343 (e) The independent organization certified under Section
4444 39.151 for the ERCOT power region may implement programs described
4545 by Subsections (d) and (f) simultaneously.
4646 (f) The commission shall require the independent
4747 organization certified under Section 39.151 for the ERCOT power
4848 region to develop and implement a program to ensure minimum
4949 generation performance during times of high reliability risk due to
5050 low operating reserves. The program must:
5151 (1) apply to each electric power generation resource
5252 in the ERCOT power region that enters into a signed generator
5353 interconnection agreement after January 1, 2026;
5454 (2) be independently evaluated by the wholesale
5555 electric market monitor, including a historical analysis;
5656 (3) allow entities, at the portfolio level, to meet
5757 the performance requirements by supplementing or contracting with
5858 on-site or off-site resources, including battery energy storage
5959 resources and load resources;
6060 (4) provide penalties for failing to comply with the
6161 performance requirements and financial incentives for exceeding
6262 those requirements, except that penalties may not apply to resource
6363 unavailability due to planned maintenance outages or physical
6464 transmission outages or during hours when the resource would not be
6565 expected to perform based on the resource type; and
6666 (5) exempt battery energy storage resources from the
6767 generation performance requirements.
6868 SECTION 3. Subchapter D, Chapter 39, Utilities Code, is
6969 amended by adding Section 39.1591 to read as follows:
7070 Sec. 39.1591. REPORT ON DISPATCHABLE AND NON-DISPATCHABLE
7171 GENERATION FACILITIES. Not later than December 1 of each year, the
7272 commission shall file a report with the legislature that:
7373 (1) includes:
7474 (A) the estimated annual costs incurred under
7575 this subchapter by dispatchable and non-dispatchable generators to
7676 guarantee that a firm amount of electric energy will be provided for
7777 the ERCOT power grid; and
7878 (B) as calculated by the independent system
7979 operator, the cumulative annual costs that have been incurred in
8080 the ERCOT market to facilitate the transmission of dispatchable and
8181 non-dispatchable electricity to load and to interconnect
8282 transmission level loads;
8383 (2) documents the status of the implementation of this
8484 subchapter, including whether the rules and protocols adopted to
8585 implement this subchapter have materially improved the
8686 reliability, resilience, and transparency of the electricity
8787 market; and
8888 (3) includes recommendations for any additional
8989 legislative measures needed to empower the commission to implement
9090 market reforms to ensure that market signals are adequate to
9191 preserve existing dispatchable generation and incentivize the
9292 construction of new dispatchable generation sufficient to maintain
9393 reliability standards for at least five years after the date of the
9494 report.
9595 SECTION 4. Subchapter D, Chapter 39, Utilities Code, is
9696 amended by adding Section 39.166 to read as follows:
9797 Sec. 39.166. RELIABILITY PROGRAM. (a) The commission may
9898 not require retail customers or load-serving entities in the ERCOT
9999 power region to purchase credits designed to support a required
100100 reserve margin or other capacity or reliability requirement until:
101101 (1) the independent organization certified under
102102 Section 39.151 for the ERCOT power region and the wholesale
103103 electric market monitor complete an updated assessment on the cost
104104 to and effects on the ERCOT market of the proposed reliability
105105 program; and
106106 (2) the independent organization certified under
107107 Section 39.151 for the ERCOT power region begins implementing real
108108 time co-optimization of energy and ancillary services in the ERCOT
109109 wholesale market.
110110 (b) The assessment required under Subsection (a) must
111111 include:
112112 (1) an evaluation of the cost of new entry and the
113113 effects of the proposed reliability program on consumer costs and
114114 the competitive retail market;
115115 (2) a compilation of detailed information regarding
116116 cost offsets realized through a reduction in costs in the energy and
117117 ancillary services markets and use of reliability unit commitments;
118118 (3) a set of metrics to measure the effects of the
119119 proposed reliability program on system reliability;
120120 (4) an evaluation of the cost to retain existing
121121 dispatchable resources in the ERCOT power region;
122122 (5) an evaluation of the planned timeline for
123123 implementation of real time co-optimization for energy and
124124 ancillary services in the ERCOT power region; and

126126 and updated ancillary service products.
127127 (c) The commission may not implement a reliability program
128128 described by Subsection (a) unless the commission by rule
129129 establishes the essential features of the program, including
130130 requirements to meet the reliability needs of the power region, and
131131 the program:
132132 (1) requires the independent organization certified
133133 under Section 39.151 for the ERCOT power region to procure the
134134 credits centrally in a manner designed to prevent market
135135 manipulation by affiliated generation and retail companies;
136136 (2) limits participation in the program to
137137 dispatchable resources with the specific attributes necessary to
138138 meet operational needs of the ERCOT power region;
139139 (3) ensures that a generator cannot receive credits
140140 that exceed the amount of generation bid into the forward market by
141141 that generator;
142142 (4) ensures that an electric generating unit can
143143 receive a credit only for being available to perform in real time
144144 during the tightest intervals of low supply and high demand on the
145145 grid, as defined by the commission on a seasonal basis;
146146 (5) establishes a penalty structure, resulting in a
147147 net benefit to load, for generators that bid into the forward market
148148 but do not meet the full obligation;
149149 (6) provides the wholesale electric market monitor
150150 with the authority and resources necessary to investigate potential
151151 instances of market manipulation by any means, including by
152152 financial or physical actions;
153153 (7) ensures that any program reliability standard
154154 reasonably balances the incremental reliability benefits to
155155 customers against the incremental costs of the program based on an
156156 evaluation by the wholesale electric market monitor;
157157 (8) establishes a single ERCOT-wide clearing price for
158158 the program and does not differentiate payments or credit values
159159 based on locational constraints;
160160 (9) does not assign costs, credit, or collateral for
161161 the program in a manner that provides a cost advantage to
162162 load-serving entities who own, or whose affiliates own, generation
163163 facilities;
164164 (10) requires sufficient secured collateral so that
165165 other market participants do not bear the risk of non-performance
166166 or non-payment;
167167 (11) ensures that the cost of all credits paid to
168168 dispatchable resources is allocated to loads based on an hourly
169169 load ratio share; and
170170 (12) removes any market changes implemented as a
171171 bridge solution for the program not later than the first
172172 anniversary of the date the program was implemented.
173173 (d) The commission and the independent organization
174174 certified under Section 39.151 for the ERCOT power region may not
175175 adopt a market rule for the ERCOT power region associated with the
176176 implementation of a reliability program described by Subsection (a)
177177 that provides a cost advantage to load-serving entities who own, or
178178 whose affiliates own, generation facilities.
179179 (e) The commission and the independent organization
180180 certified under Section 39.151 for the ERCOT power region shall
181181 ensure that the net cost imposed on the ERCOT market for the credits
182182 does not exceed $1 billion annually, less the cost of any interim or
183183 bridge solutions that are lawfully implemented, except that the
184184 commission may adjust the limit:
185185 (1) proportionally according to the highest net peak
186186 demand year-over-year with a base year of 2026; and
187187 (2) for inflation with a base year of 2026.
188188 (f) The wholesale electric market monitor biennially shall:
189189 (1) evaluate the incremental reliability benefits of
190190 the program for consumers compared to the costs to consumers of the
191191 program and the costs in the energy and ancillary services markets;
192192 and
193193 (2) report the results of each evaluation to the
194194 legislature.
195195 SECTION 5. (a) Not later than September 1, 2024, the
