Sempra Grid Modernization, $65 B Capital Plan, $36 B Oncor Investment, and $13 B 2026 Deployment (2024-2026)

Grid Modernization Risks, Sempra Navigates Execution and Supply Chains

U.S. utilities are escalating capital expenditures to unprecedented levels to meet a structural surge in electricity demand, but this rapid scale-up introduces significant execution, regulatory, and supply chain risks that threaten project timelines and costs. The focus has shifted from incremental upgrades for reliability to a full-scale race to build capacity, primarily driven by the power needs of new data centers and broad industrial electrification. This pivot has exposed critical vulnerabilities in the industrial base required to support such a build-out.

• Between 2021 and 2024, utility capital plans centered on grid resilience against extreme weather events and gradual modernization. During this period, Sempra operated under what was then a record $48 billion five-year plan, a figure that reflected a steady, predictable approach to upgrading aging infrastructure. The primary risk was managing discrete, regional projects.
• The period from 2025 to today is defined by a dramatic acceleration in response to revised load forecasts. Sempra’s capital plan jumped by over 35% to a new $65 billion five-year program announced in May 2026. This abrupt escalation, mirrored across the industry, immediately intensified pressure on an already constrained supply chain for essential components like large power transformers and high-voltage switchgear.
• The risk profile has fundamentally changed from managing contained infrastructure projects to navigating a systemic, industry-wide capacity shortage. The primary challenge is no longer just securing project financing but securing the physical equipment and skilled labor needed for execution in a highly competitive market where project lead times are extending significantly.

$65 B Capital Plan, Sempra Accelerates Investment for Grid Capacity

Sempra’s capital investment strategy shows a marked acceleration in 2025-2026, shifting from a previously record-high plan to a new, larger commitment that reflects the urgent need to expand grid capacity in high-growth markets. This front-loaded spending program is designed to address immediate demand pressures, particularly in Texas, and build a rate base that supports long-term earnings growth.

• Sempra’s five-year capital plan escalated from $48 billion for the 2024-2028 period to a new record of $65 billion for the subsequent five-year window, a clear indicator of the rising costs and expanding scope of grid modernization requirements.
• The planned capital deployment for the 2026 fiscal year alone is nearly $13 billion. This intense, front-loaded schedule is intended to get ahead of projected demand surges and underpins the company’s guidance for a 12% adjusted EPS growth target for the year.
• A substantial portion of this capital is channeled through its majority-owned Texas subsidiary, Oncor. Oncor announced its own aggressive $36 billion five-year capital plan for 2025-2029, with a strategic allocation of 60%, or approximately $21.6 billion, specifically for transmission projects to enhance grid stability and connect new generation.

Sempra 2 Strategic Alliances, Oncor and Conoco Phillips (2025)

Sempra’s execution strategy relies on two distinct partnership models: vertically integrated operational control through its subsidiary Oncor for regulated grid investment, and strategic commercial agreements with off-takers like Conoco Phillips for its non-regulated infrastructure projects. This dual approach allows the company to direct massive, rate-based investments while de-risking its large-scale energy export ventures.

• The primary vehicle for executing the Texas grid modernization is Sempra’s majority ownership in Oncor. This structure gives Sempra direct operational influence over the deployment of Oncor’s $36 billion capital plan, ensuring alignment with its broader corporate strategy and financial targets.
• In its non-regulated Sempra Infrastructure business, the company mitigates financial risk through long-term partnerships. The 20-year sales and purchase agreement with Conoco Phillips for the Port Arthur LNG project provides a guaranteed revenue stream that is essential for securing project financing for the multi-billion-dollar facility.
• Sempra also explicitly defines its relationship with policymakers and regulators as a form of collaborative partnership. This engagement is critical for aligning its infrastructure investments with state energy policies and, most importantly, for securing the regulatory approvals needed for timely cost recovery on its massive capital outlays.

Texas and California, Sempra’s Concentrated Geographic Strategy

Sempra’s capital deployment is highly concentrated in Texas and California, two markets with divergent regulatory environments but a shared, urgent need for grid expansion driven by economic growth and energy transition policies. The recent acceleration in investment, however, shows a distinct strategic pivot toward Texas to meet its exceptional load growth.

• From 2021 to 2024, Sempra’s investments were more evenly balanced across its California (SDG&E) and Texas (Oncor) utilities, with a heavy focus on wildfire mitigation, public safety, and initial grid resilience measures in California.
• Beginning in 2025, the strategic emphasis and the bulk of new capital have decisively shifted towards Texas. Oncor’s $36 billion plan, with its massive $21.6 billion allocation to new transmission lines, is a direct response to the state’s projected load growth, which is among the highest in the nation due to data center proliferation and industrial expansion.
• California remains a core market, with ongoing investments directed at grid hardening, integrating a high percentage of renewable resources, and managing the demands of building and vehicle electrification. However, the sheer scale of new, concentrated industrial demand in Texas has made it the primary growth engine and the focus of Sempra’s most aggressive capital deployment.

Grid Modernization Technology, Sempra Deploys at Commercial Scale

The technologies underpinning “grid modernization” are commercially mature, but the current challenge is deploying them at an unprecedented scale and speed, shifting the bottleneck from technology development to manufacturing capacity and project execution. The issue is not a lack of innovation but a shortage of the foundational industrial components needed for a nationwide grid build-out.

• Between 2021 and 2024, the deployment of grid technologies focused on improving efficiency at the distribution level. This included targeted rollouts of Advanced Metering Infrastructure (AMI) and distribution automation systems to enhance outage management and enable dynamic pricing.
• From 2025 onward, the investment focus has pivoted to the bulk power system. This involves the large-scale deployment of high-voltage transmission lines, new and expanded substations, and advanced grid control software designed to manage the highly variable loads from data centers and intermittent renewable generation. The successful operation of the digital grid is a core focus for companies like Aramco as well.
• While the core technologies like transformers, conductors, and control systems are well-established, the sudden, industry-wide surge in demand has exposed critical supply chain vulnerabilities. Lead times for large power transformers have stretched to years, not months, indicating a severe misalignment between the energy industry’s deployment ambitions and the manufacturing sector’s capacity to deliver.

$65 B Plan, Sempra Strengths and Execution Risks

Sempra’s strategic position is defined by its access to high-growth regulated markets, but its success in executing its $65 billion plan hinges on overcoming significant external threats related to supply chains and regulatory pushback on rate increases. The company is well-positioned to capitalize on a major secular trend, but the path is exposed to considerable macroeconomic and logistical friction.

• The company’s primary strength is its established, large-scale utility operations in Texas and California. These regions are at the epicenter of U.S. economic growth and electrification, providing a clear and compelling demand driver for new infrastructure investment.
• A key internal weakness is the sheer scale and complexity of simultaneously executing multiple billion-dollar projects. This massive undertaking creates significant exposure to construction cost inflation, labor shortages, and logistical challenges.
• The main opportunity is to solidify Sempra’s position as a critical infrastructure provider for the digital and clean energy economies. Successfully building out the grid in its service territories will generate stable, regulated returns for decades.
• The most significant external threat is a combination of severe supply chain bottlenecks for critical grid components and potential public or regulatory opposition to the substantial electricity rate increases required to fund the $65 billion investment.

Sempra 2026 Scenario, Will Oncor’s $36 B Plan Meet Texas Demand?

The critical variable for Sempra in 2026 is whether its subsidiary Oncor can execute its capital plan fast enough to stay ahead of Texas’s surging power demand without facing significant delays from supply chain or regulatory hurdles. The company’s financial targets and its ability to support regional economic growth depend on its performance on this front.

• If Sempra and Oncor can secure timely delivery of large power transformers and other critical long-lead-time equipment, watch for an acceleration of new transmission project construction in the ERCOT footprint, particularly lines designed to serve data center hubs.
• If regulatory approvals for rate recovery from the Public Utility Commission of Texas are delayed or the approved returns are lower than requested, watch for potential downward revisions to the outer years of the capital plan or a negative impact on the company’s 12% EPS growth target.
• The most recent data from 2025-2026 shows a clear industry trend of front-loading capital to address the most urgent needs. The key signal to watch is whether Sempra’s quarterly capital deployment figures in 2026 consistently track toward its nearly $13 billion annual target, as any deviation could signal emerging execution problems.
