Oncor Reports Third Quarter 2024 Results

DALLAS (November 6, 2024) — Oncor Electric Delivery Company LLC (“Oncor”) today reported three months ended September 30, 2024 net income of $324 million compared to three months ended September 30, 2023 net income of $380 million. The $56 million decrease was driven by higher interest expense and depreciation expense associated with increases in invested capital and higher operation and maintenance expense, partially offset by overall higher revenues primarily attributable to updated interim rates to reflect increases in invested capital, increases in transmission billing units and customer growth, net of lower revenues due to lower customer consumption primarily attributable to milder weather when compared to the prior period and lower energy efficiency program performance bonus revenues due to the timing of Public Utility Commission of Texas (“PUCT”) approval of an annual energy efficiency cost recovery factor application.

“I am incredibly proud of our team’s strong financial and operational performance this quarter. Our dedicated employees have continued to deliver exceptional results, executing on unprecedented growth, reflecting our commitment to investing in critical infrastructure to support Texas’s growing energy needs,” said Allen Nye, CEO of Oncor. “I also want to extend my deepest gratitude to our crews who spent weeks restoring service in hurricane-ravaged areas of Florida, Georgia and North Carolina. Their hard work and dedication in helping fellow Americans in need embody the very spirit and mission of our company, and our dedication to the communities we serve.”

Oncor’s reported net income of $800 million in the nine months ended September 30, 2024 compared favorably to net income of $683 million in the nine months ended September 30, 2023. The $117 million increase was driven by overall higher revenues primarily attributable to updated interim rates to reflect increases in invested capital, increases in transmission billing units, customer growth and the new base rates implemented in May 2023, net of lower revenues due to lower customer consumption primarily attributable to milder weather when compared to the prior period and lower energy efficiency program performance bonus revenues due to the timing of PUCT approval of an

annual energy efficiency cost recovery factor application and the write-off of rate base disallowances recorded in the first quarter of 2023, partially offset by higher interest expense and depreciation expense associated with increases in invested capital and higher operation and maintenance expense. Financial and operational results are provided in Tables A, B, C, D and E below.

Regulatory Update

In August, Oncor filed an unopposed settlement agreement for PUCT review and approval in its system resiliency plan proceeding (PUCT Docket No. 56545). The system resiliency plan outlined in the settlement agreement provides for approximately $2.9 billion in capital expenditures and $520 million in operation and maintenance expenses to enhance the resiliency of Oncor’s transmission and distribution system, including measures to address extreme weather, wildfires, physical security threats and cybersecurity threats. The plan provides for the majority of the spend to occur over a three-year period, with approximately $300 million in capital expenditures and approximately $20 million in operation and maintenance expenses to be carried over into a fourth year. Oncor expects the PUCT will issue a final order in the proceeding by the end of this year, and, to the extent its system resiliency plan is approved by the PUCT, anticipates beginning to make the investments contemplated by the plan in the fourth quarter of 2024.

In October, the PUCT issued an order approving the Permian Basin Reliability Plan proposed by the Electric Reliability Council of Texas, Inc. (“ERCOT”) to address anticipated long-term transmission capacity needs in the Permian Basin (PUCT Docket No. 55718). The Permian Basin Reliability Plan identifies an estimated over $13 billion in capital investment transmission projects to be completed through 2038, with those projects to be assigned by the PUCT to transmission service providers in Texas. Based on its current operations in the Permian Basin region and the initial project assignment recommendations made by ERCOT (PUCT Docket No. 57152), Oncor anticipates it could receive a significant portion of the final Permian Basin Reliability Plan transmission projects.

Operational Highlights

Oncor continues to support Texas’ growth with new construction, including projects designed to increase reliability for the ERCOT market. In the three months ended September 30, 2024, Oncor constructed or upgraded over 800 miles of distribution and transmission lines, all while remaining focused on safety and reliability. Oncor connected 19,000 new premises to the ERCOT grid and placed nearly $140 million of transmission projects, including eight load-serving substations, into service in the third quarter of 2024.

In the third quarter of 2024, Oncor entered 121 new transmission point of interconnection (“POI”) requests into queue, a 38% increase over the same period in 2023. The majority of those new requests

are from large commercial and industrial (“LC&I”) customers. At September 30, 2024, Oncor had a total of 884 active generation and LC&I transmission POI requests in queue. Generation customers represented 505 of those active POI requests in queue of which 44% are solar, 44% are storage, 7% are wind, 4% are gas and 1% are other. LC&I customers represented 379 of those active POI requests, an increase of 23% over September 30, 2023, equaling 103 gigawatts of potential load. These requests arise from a diverse group of industries, including artificial intelligence and data centers, which equal approximately 82 gigawatts of the potential load. Large load customers, each seeking 100 megawatts or more of demand, represented 172 of the active POI requests at September 30, 2024.

Oncor currently expects to announce a new five-year capital expenditure plan for 2025 through 2029 in the first quarter of 2025 that projects an increase of 40-50% over its previously announced 2024 through 2028 capital plan of $24.2 billion, largely driven by forecasted growth of customer demand in ERCOT.

Liquidity

As of November 5, 2024, Oncor’s available liquidity, consisting of cash on hand and available borrowing capacity under its existing credit facilities, commercial paper program and accounts receivable facility (“AR Facility”), totaled $1.9 billion.

(a) SAIDI is the average number of minutes electric service is interrupted per consumer in a twelve-month period. SAIFI is the average number of electric service interruptions per consumer in a twelve-month period. CAIDI is the average duration in minutes per electric service interruption in a twelve-month period. In each case, Oncor’s non-storm reliability performance reflects electric service interruptions of one minute or more per customer. Each of these results excludes outages during significant storm events.

(b) Degree days are measures of how warm or cold it is throughout Oncor’s service territory. A degree day compares the average of the hourly outdoor temperatures during each day to a 65° Fahrenheit standard temperature. The more extreme the outside temperature, the higher the number of degree days. A high number of degree days generally results in higher levels of energy use for space cooling or heating.

(a) Distribution base revenues from residential customers are generally based on actual monthly consumption (kWh). On a weather-normalized basis, distribution base revenues from residential customers increased 13.3% in the three months ended September 30, 2024 as compared to the three months ended September 30, 2023 and increased 17.3% in the nine months ended September 30, 2024 as compared to the nine months ended September 30, 2023.

(b) Depending on size and annual load factor, distribution base revenues from LC&I customers are generally based either on actual monthly demand (kilowatts) or the greater of actual monthly demand (kilowatts) or 80% of peak monthly demand during the prior eleven months.

(c) Includes distribution base revenues from small business customers whose billing is generally based on actual monthly consumption (kWh), lighting sites and other miscellaneous distribution base revenues.

(d) The 1.8% increase in distribution base revenues in the three months ended September 30, 2024 as compared to the three months ended September 30, 2023 (11.1% increase on a weather-normalized basis) primarily reflects updated interim distribution cost recovery factor rates and growth in points of delivery, partially offset by lower customer consumption primarily attributable to milder weather when compared to the prior period. The 10.6% increase in distribution base revenues in the nine months ended September 30, 2024 as compared to the nine months ended September, 2023 (13.4% increase on a weather-normalized basis) primarily reflects updated interim distribution cost recovery factor rates, new base rates implemented May 1, 2023 and growth in points of delivery, partially offset by lower customer consumption primarily attributable to milder weather when compared to the prior period.
