---|
11 | 11 | | SECTION 1. The heading to Section 39.159, Utilities Code, |
---|
12 | 12 | | as added by Chapter 426 (S.B. 3), Acts of the 87th Legislature, |
---|
13 | 13 | | Regular Session, 2021, is amended to read as follows: |
---|
14 | 14 | | Sec. 39.159. POWER REGION RELIABILITY AND DISPATCHABLE |
---|
15 | 15 | | GENERATION. |
---|
16 | 16 | | SECTION 2. Section 39.159, Utilities Code, as added by |
---|
17 | 17 | | Chapter 426 (S.B. 3), Acts of the 87th Legislature, Regular |
---|
18 | 18 | | Session, 2021, is amended by adding Subsections (d), (e), and (f) to |
---|
19 | 19 | | read as follows: |
---|
20 | 20 | | (d) The commission shall require the independent |
---|
21 | 21 | | organization certified under Section 39.151 for the ERCOT power |
---|
22 | 22 | | region to consider implementing an ancillary services program to |
---|
23 | 23 | | procure dispatchable reliability reserve services on a day-ahead |
---|
24 | 24 | | and real-time basis to account for market uncertainty. The program |
---|
25 | 25 | | to be considered may: |
---|
26 | 26 | | (1) determine the quantity of services necessary based |
---|
27 | 27 | | on historical variations in generation availability for each season |
---|
28 | 28 | | based on a targeted reliability standard or goal, including |
---|
29 | 29 | | intermittency of non-dispatchable generation facilities and forced |
---|
30 | 30 | | outage rates, for dispatchable generation facilities; |
---|
31 | 31 | | (2) develop criteria for resource participation that |
---|
32 | 32 | | require a resource to: |
---|
33 | 33 | | (A) be capable of running for at least four hours |
---|
34 | 34 | | at the resource's high sustained limit or for more than four hours |
---|
35 | 35 | | as the organization determines is needed; |
---|
36 | 36 | | (B) be online and dispatchable not more than two |
---|
37 | 37 | | hours after being called on for deployment; and |
---|
38 | 38 | | (C) have the dispatchable flexibility to address |
---|
39 | 39 | | inter-hour operational challenges; and |
---|
40 | 40 | | (3) reduce the amount of reliability unit commitment |
---|
41 | 41 | | by the amount of dispatchable reliability reserve services procured |
---|
42 | 42 | | under this section. |
---|
43 | 43 | | (e) The independent organization certified under Section |
---|
44 | 44 | | 39.151 for the ERCOT power region may implement programs described |
---|
45 | 45 | | by Subsections (d) and (f) simultaneously. |
---|
46 | 46 | | (f) The commission shall require the independent |
---|
47 | 47 | | organization certified under Section 39.151 for the ERCOT power |
---|
48 | 48 | | region to develop and implement a program to ensure minimum |
---|
49 | 49 | | generation performance during times of high reliability risk due to |
---|
50 | 50 | | low operating reserves. The program must: |
---|
51 | 51 | | (1) apply to each electric power generation resource |
---|
52 | 52 | | in the ERCOT power region that enters into a signed generator |
---|
53 | 53 | | interconnection agreement after January 1, 2026; |
---|
54 | 54 | | (2) be independently evaluated by the wholesale |
---|
55 | 55 | | electric market monitor, including a historical analysis; |
---|
56 | 56 | | (3) allow entities, at the portfolio level, to meet |
---|
57 | 57 | | the performance requirements by supplementing or contracting with |
---|
58 | 58 | | on-site or off-site resources, including battery energy storage |
---|
59 | 59 | | resources and load resources; |
---|
60 | 60 | | (4) provide penalties for failing to comply with the |
---|
61 | 61 | | performance requirements and financial incentives for exceeding |
---|
62 | 62 | | those requirements, except that penalties may not apply to resource |
---|
63 | 63 | | unavailability due to planned maintenance outages or physical |
---|
64 | 64 | | transmission outages or during hours when the resource would not be |
---|
65 | 65 | | expected to perform based on the resource type; and |
---|
66 | 66 | | (5) exempt battery energy storage resources from the |
---|
67 | 67 | | generation performance requirements. |
---|
68 | 68 | | SECTION 3. Subchapter D, Chapter 39, Utilities Code, is |
---|
69 | 69 | | amended by adding Section 39.1591 to read as follows: |
---|
70 | 70 | | Sec. 39.1591. REPORT ON DISPATCHABLE AND NON-DISPATCHABLE |
---|
71 | 71 | | GENERATION FACILITIES. Not later than December 1 of each year, the |
---|
72 | 72 | | commission shall file a report with the legislature that: |
---|
73 | 73 | | (1) includes: |
---|
74 | 74 | | (A) the estimated annual costs incurred under |
---|
75 | 75 | | this subchapter by dispatchable and non-dispatchable generators to |
---|
76 | 76 | | guarantee that a firm amount of electric energy will be provided for |
---|
77 | 77 | | the ERCOT power grid; and |
---|
78 | 78 | | (B) as calculated by the independent system |
---|
79 | 79 | | operator, the cumulative annual costs that have been incurred in |
---|
80 | 80 | | the ERCOT market to facilitate the transmission of dispatchable and |
---|
81 | 81 | | non-dispatchable electricity to load and to interconnect |
---|
82 | 82 | | transmission level loads; |
---|
83 | 83 | | (2) documents the status of the implementation of this |
---|
84 | 84 | | subchapter, including whether the rules and protocols adopted to |
---|
85 | 85 | | implement this subchapter have materially improved the |
---|
86 | 86 | | reliability, resilience, and transparency of the electricity |
---|
87 | 87 | | market; and |
---|
88 | 88 | | (3) includes recommendations for any additional |
---|
89 | 89 | | legislative measures needed to empower the commission to implement |
---|
90 | 90 | | market reforms to ensure that market signals are adequate to |
---|
91 | 91 | | preserve existing dispatchable generation and incentivize the |
---|
92 | 92 | | construction of new dispatchable generation sufficient to maintain |
---|
93 | 93 | | reliability standards for at least five years after the date of the |
---|
94 | 94 | | report. |
---|
95 | 95 | | SECTION 4. Subchapter D, Chapter 39, Utilities Code, is |
---|
96 | 96 | | amended by adding Section 39.166 to read as follows: |
---|
97 | 97 | | Sec. 39.166. RELIABILITY PROGRAM. (a) The commission may |
---|
98 | 98 | | not require retail customers or load-serving entities in the ERCOT |
---|
99 | 99 | | power region to purchase credits designed to support a required |
---|
100 | 100 | | reserve margin or other capacity or reliability requirement until: |
---|
101 | 101 | | (1) the independent organization certified under |
---|
102 | 102 | | Section 39.151 for the ERCOT power region and the wholesale |
---|
103 | 103 | | electric market monitor complete an updated assessment on the cost |
---|
104 | 104 | | to and effects on the ERCOT market of the proposed reliability |
---|
105 | 105 | | program; and |
---|
106 | 106 | | (2) the independent organization certified under |
---|
107 | 107 | | Section 39.151 for the ERCOT power region begins implementing real |
---|
108 | 108 | | time co-optimization of energy and ancillary services in the ERCOT |
---|
109 | 109 | | wholesale market. |
---|
110 | 110 | | (b) The assessment required under Subsection (a) must |
---|
111 | 111 | | include: |
---|
112 | 112 | | (1) an evaluation of the cost of new entry and the |
---|
113 | 113 | | effects of the proposed reliability program on consumer costs and |
---|
114 | 114 | | the competitive retail market; |
---|
115 | 115 | | (2) a compilation of detailed information regarding |
---|
116 | 116 | | cost offsets realized through a reduction in costs in the energy and |
---|
117 | 117 | | ancillary services markets and use of reliability unit commitments; |
---|
118 | 118 | | (3) a set of metrics to measure the effects of the |
---|
119 | 119 | | proposed reliability program on system reliability; |
---|
120 | 120 | | (4) an evaluation of the cost to retain existing |
---|
121 | 121 | | dispatchable resources in the ERCOT power region; |
---|
122 | 122 | | (5) an evaluation of the planned timeline for |
---|
123 | 123 | | implementation of real time co-optimization for energy and |
---|
124 | 124 | | ancillary services in the ERCOT power region; and |
---|
125 | 125 | | (6) anticipated market and reliability effects of new |
---|
126 | 126 | | and updated ancillary service products. |
---|
127 | 127 | | (c) The commission may not implement a reliability program |
---|
128 | 128 | | described by Subsection (a) unless the commission by rule |
---|
129 | 129 | | establishes the essential features of the program, including |
---|
130 | 130 | | requirements to meet the reliability needs of the power region, and |
---|
131 | 131 | | the program: |
---|
132 | 132 | | (1) requires the independent organization certified |
---|
133 | 133 | | under Section 39.151 for the ERCOT power region to procure the |
---|
134 | 134 | | credits centrally in a manner designed to prevent market |
---|
135 | 135 | | manipulation by affiliated generation and retail companies; |
---|
136 | 136 | | (2) limits participation in the program to |
---|
137 | 137 | | dispatchable resources with the specific attributes necessary to |
---|
138 | 138 | | meet operational needs of the ERCOT power region; |
---|
139 | 139 | | (3) ensures that a generator cannot receive credits |
---|
140 | 140 | | that exceed the amount of generation bid into the forward market by |
---|
141 | 141 | | that generator; |
---|
142 | 142 | | (4) ensures that an electric generating unit can |
---|
143 | 143 | | receive a credit only for being available to perform in real time |
---|
144 | 144 | | during the tightest intervals of low supply and high demand on the |
---|
145 | 145 | | grid, as defined by the commission on a seasonal basis; |
---|
146 | 146 | | (5) establishes a penalty structure, resulting in a |
---|
147 | 147 | | net benefit to load, for generators that bid into the forward market |
---|
148 | 148 | | but do not meet the full obligation; |
---|
149 | 149 | | (6) provides the wholesale electric market monitor |
---|
150 | 150 | | with the authority and resources necessary to investigate potential |
---|
151 | 151 | | instances of market manipulation by any means, including by |
---|
152 | 152 | | financial or physical actions; |
---|
153 | 153 | | (7) ensures that any program reliability standard |
---|
154 | 154 | | reasonably balances the incremental reliability benefits to |
---|
155 | 155 | | customers against the incremental costs of the program based on an |
---|
156 | 156 | | evaluation by the wholesale electric market monitor; |
---|
157 | 157 | | (8) establishes a single ERCOT-wide clearing price for |
---|
158 | 158 | | the program and does not differentiate payments or credit values |
---|
159 | 159 | | based on locational constraints; |
---|
160 | 160 | | (9) does not assign costs, credit, or collateral for |
---|
161 | 161 | | the program in a manner that provides a cost advantage to |
---|
162 | 162 | | load-serving entities who own, or whose affiliates own, generation |
---|
163 | 163 | | facilities; |
---|
164 | 164 | | (10) requires sufficient secured collateral so that |
---|
165 | 165 | | other market participants do not bear the risk of non-performance |
---|
166 | 166 | | or non-payment; |
---|
167 | 167 | | (11) ensures that the cost of all credits paid to |
---|
168 | 168 | | dispatchable resources is allocated to loads based on an hourly |
---|
169 | 169 | | load ratio share; and |
---|
170 | 170 | | (12) removes any market changes implemented as a |
---|
171 | 171 | | bridge solution for the program not later than the first |
---|
172 | 172 | | anniversary of the date the program was implemented. |
---|
173 | 173 | | (d) The commission and the independent organization |
---|
174 | 174 | | certified under Section 39.151 for the ERCOT power region may not |
---|
175 | 175 | | adopt a market rule for the ERCOT power region associated with the |
---|
176 | 176 | | implementation of a reliability program described by Subsection (a) |
---|
177 | 177 | | that provides a cost advantage to load-serving entities who own, or |
---|
178 | 178 | | whose affiliates own, generation facilities. |
---|
179 | 179 | | (e) The commission and the independent organization |
---|
180 | 180 | | certified under Section 39.151 for the ERCOT power region shall |
---|
181 | 181 | | ensure that the net cost imposed on the ERCOT market for the credits |
---|
182 | 182 | | does not exceed $1 billion annually, less the cost of any interim or |
---|
183 | 183 | | bridge solutions that are lawfully implemented, except that the |
---|
184 | 184 | | commission may adjust the limit: |
---|
185 | 185 | | (1) proportionally according to the highest net peak |
---|
186 | 186 | | demand year-over-year with a base year of 2026; and |
---|
187 | 187 | | (2) for inflation with a base year of 2026. |
---|
188 | 188 | | (f) The wholesale electric market monitor biennially shall: |
---|
189 | 189 | | (1) evaluate the incremental reliability benefits of |
---|
190 | 190 | | the program for consumers compared to the costs to consumers of the |
---|
191 | 191 | | program and the costs in the energy and ancillary services markets; |
---|
192 | 192 | | and |
---|
193 | 193 | | (2) report the results of each evaluation to the |
---|
194 | 194 | | legislature. |
---|
195 | 195 | | SECTION 5. (a) Not later than September 1, 2024, the |
