CPS Energy, San Antonio's municipally owned electric and gas utility, has long been celebrated as one of the largest public utilities in the United States — a point of civic pride for a city that controls its own energy destiny rather than answering to shareholder-driven corporations. But 2025 and 2026 have thrust the utility into an uncomfortable spotlight, as infrastructure failures, rising rates, and mounting legal liability are forcing residents and policymakers alike to ask hard questions about whether CPS Energy is delivering on its fundamental promise: safe, reliable, affordable energy.
The latest flashpoint is a series of home explosions on Preston Hollow, a residential area that has become ground zero for what may become one of the most significant infrastructure liability cases in the utility's history. A second lawsuit has now been filed over those explosions, signaling that the legal fallout is just beginning. Understanding what CPS Energy is, how it operates, and why these failures matter requires stepping back and looking at the full picture.
What Is CPS Energy and Why Does It Matter?
CPS Energy — formally City Public Service Energy — is the largest municipally owned combined electric and gas utility in the United States. It serves approximately 930,000 electric customers and 365,000 natural gas customers across the greater San Antonio metropolitan area. Unlike investor-owned utilities such as Oncor or NRG, CPS Energy is owned by the citizens of San Antonio and governed by a Board of Trustees appointed by the City Council.
This structure has real implications. Profits don't flow to Wall Street shareholders — they flow back into city services, with CPS Energy historically contributing hundreds of millions of dollars annually to the City of San Antonio's general fund. In fiscal year 2023 alone, that contribution approached $380 million, helping fund everything from parks to public safety.
The utility traces its roots to 1860, when San Antonio first developed a municipal gas system. Over more than 160 years, it has grown into a vertically integrated operation that owns generation assets, transmission infrastructure, and a sprawling distribution network that snakes beneath the streets and into the walls of nearly a million homes and businesses. That underground network — aging in many sections, stressed by explosive population growth — is now at the center of a safety reckoning.
The Preston Hollow Explosions: What Happened
The home explosions on Preston Hollow represent one of the most alarming infrastructure incidents in CPS Energy's recent history. Multiple homes were damaged or destroyed in what investigators believe was connected to the utility's natural gas distribution infrastructure. The human cost — displacement, injury, property loss, and the psychological trauma of watching a home detonate — is incalculable in purely financial terms.
Lawsuits have followed swiftly. The filing of a second lawsuit over the Preston Hollow explosions signals that plaintiffs' attorneys see this as a viable case of utility negligence — that CPS Energy either knew or should have known about vulnerabilities in its gas distribution infrastructure in that area and failed to take corrective action. In Texas, municipal utilities enjoy certain legal protections that private utilities don't, but those protections are not absolute when gross negligence can be demonstrated.
Gas line explosions rarely happen without warning signs. Corrosion, improper pressure regulation, aging pipe materials — these are detectable problems that routine inspection programs are supposed to catch. When a home explodes, the legal question is almost always: what did the utility know, and when did it know it?
For residents living near aging gas infrastructure anywhere in San Antonio, the Preston Hollow incident is a sobering reminder that basic safety equipment is not optional. A quality natural gas leak detector can provide early warning before pressure builds to catastrophic levels. Similarly, a combination carbon monoxide and gas detector offers dual protection against two invisible household killers.
Winter Storm Uri: The Wound That Won't Fully Heal
The Preston Hollow lawsuits don't emerge from a vacuum. They land on a utility that has been under sustained scrutiny since February 2021, when Winter Storm Uri pushed Texas's power grid to the edge of catastrophic failure. CPS Energy customers lost power for days in subfreezing temperatures. Dozens of Texans died statewide. The human suffering was immense.
CPS Energy faced intense criticism for its handling of the storm — both for the outages themselves and for the financial fallout. The utility borrowed approximately $1 billion to cover the extraordinary cost of fuel and purchased power during the storm, a debt that ultimately translated into rate increases for customers. Critics argued that years of deferred weatherization investments left the system unnecessarily vulnerable.
To its credit, CPS Energy has since invested significantly in weatherizing its generation fleet and hardening its infrastructure. But trust, once fractured, is slow to rebuild — and each subsequent infrastructure failure refreshes the wound.
Infrastructure Age and the Hidden Cost of Growth
San Antonio is one of the fastest-growing large cities in America. The metro area has added hundreds of thousands of residents over the past decade, straining roads, schools, water systems — and energy infrastructure. CPS Energy must simultaneously maintain and expand its network, a task that requires capital investment at a pace that rate revenue sometimes struggles to match.
The utility's natural gas distribution system includes thousands of miles of pipeline, some of it installed decades ago using materials and methods that don't meet modern standards. Cast iron and bare steel pipes, common in older sections of San Antonio, are prone to corrosion and leakage. Replacing them is expensive and disruptive — but the alternative, as Preston Hollow illustrates, can be catastrophic.
The Pipeline and Hazardous Materials Safety Administration (PHMSA) regulates gas distribution safety at the federal level and requires utilities to implement Distribution Integrity Management Programs (DIMP) to identify and mitigate risks. Whether CPS Energy's DIMP adequately flagged the Preston Hollow area before the explosions is a central question that litigation will likely probe.
Rate Increases and the Affordability Squeeze
At the same time that reliability concerns mount, CPS Energy customers are facing a sustained period of rate increases. Post-Uri debt repayment, fuel cost volatility, infrastructure investment, and the transition toward cleaner energy sources have all contributed to higher bills. The utility has sought multiple rate adjustments since 2021, each one adding to the financial burden on residential customers — particularly lower-income households who spend a disproportionate share of their income on energy.
San Antonio has a significant population of cost-burdened households, and energy poverty is a genuine concern. CPS Energy offers assistance programs including the REAP (Residential Energy Assistance Program) and discounted rates for qualifying low-income customers, but advocates argue that program enrollment remains lower than need would suggest, partly because the application process creates friction for the most vulnerable applicants.
The tension here is real: the utility needs revenue to fund the very infrastructure improvements that would prevent incidents like Preston Hollow. But squeezing customers who are already stretched thin is both inequitable and politically untenable. Finding the right balance — and communicating it honestly — is one of the central governance challenges CPS Energy faces.
The Renewable Energy Transition: Progress and Pressure
On the generation side, CPS Energy has made genuine progress toward a cleaner portfolio. The utility has set ambitious goals for solar and battery storage deployment, and it has been retiring older, less efficient fossil fuel generation assets. Its "Flexible Path" integrated resource plan envisions a dramatically lower-carbon generation mix by the mid-2030s.
This transition is both environmentally necessary and economically complex. Solar and wind generation have become extraordinarily cost-competitive, but they require backup capacity and storage to handle the variability that Winter Storm Uri so brutally exposed. Battery storage — specifically utility-scale systems — is improving rapidly, and CPS Energy has been among the more aggressive municipal utilities in pursuing storage contracts.
For homeowners looking to reduce dependence on the grid, the market for residential solar-plus-storage has matured significantly. A home solar panel kit or a portable power station for home backup can provide meaningful resilience during outages — a lesson many San Antonio residents absorbed the hard way in February 2021.
Analysis: What the Preston Hollow Lawsuits Signal
The second lawsuit filed over the Preston Hollow explosions is more than a legal development — it's a signal about the state of infrastructure accountability in America. Municipal utilities have historically operated with significant deference from the communities they serve. The logic was straightforward: these are public entities, accountable to elected officials, not profit-hungry corporations cutting maintenance budgets to boost quarterly earnings.
But that deference has limits. When a publicly owned utility allows aging infrastructure to reach the point of catastrophic failure, the public ownership doesn't diminish the harm — it arguably amplifies the betrayal. These are your neighbors' tax dollars paying for a system that blew up their homes.
The litigation will likely focus on several key questions: What was the condition of the gas infrastructure in the Preston Hollow area prior to the explosions? What inspection records exist? Were any risk indicators flagged and ignored? Were resources allocated appropriately given known risks?
The answers matter not just for the plaintiffs who lost their homes, but for the hundreds of thousands of CPS Energy customers living above aging gas lines across San Antonio. If the lawsuits reveal systemic inspection failures, the pressure for a comprehensive infrastructure audit — and the investment that follows — will be difficult to resist.
This pattern of infrastructure failure followed by legal accountability and eventual systemic reform is not unique to utilities. It echoes across sectors where aging systems meet modern liability standards. The financial consequences of ignoring infrastructure risk, as utilities and municipalities across the country are learning, far exceed the cost of proactive maintenance.
Frequently Asked Questions About CPS Energy
Is CPS Energy a private company or government-owned?
CPS Energy is municipally owned — it belongs to the citizens of San Antonio. It is governed by a Board of Trustees appointed by the San Antonio City Council, not by shareholders. This makes it fundamentally different from investor-owned utilities and means its financial decisions are subject to public oversight and political accountability.
What should I do if I smell gas near my home?
Leave the area immediately without operating any switches, outlets, or appliances. Do not use your phone until you're a safe distance away. Call CPS Energy's 24-hour emergency line (1-800-870-1006) and 911 from a safe location. Do not re-enter the structure until emergency personnel have cleared it. Installing a natural gas alarm detector in your home provides an early warning before concentrations reach dangerous levels.
How do I apply for CPS Energy financial assistance programs?
CPS Energy offers several assistance programs including REAP (Residential Energy Assistance Partnership) and the LITE-UP Texas program for low-income customers. You can apply through CPS Energy's website, by calling their customer service line, or through partner social service agencies. Eligibility is generally based on household income relative to federal poverty guidelines.
What caused the Preston Hollow home explosions?
The specific cause is the subject of ongoing investigation and litigation. Lawsuits allege CPS Energy's natural gas infrastructure was involved, and plaintiffs are seeking damages. The full scope of liability will be determined through the legal process.
Is CPS Energy's electric grid connected to the Texas ERCOT grid?
Yes. CPS Energy is a member of ERCOT (Electric Reliability Council of Texas), which means it operates within the largely isolated Texas grid. This was a significant factor during Winter Storm Uri — the Texas grid's limited interconnections with other regional grids meant there was little ability to import power when the system was strained. This isolation is both a feature (it keeps Texas largely free from federal regulation) and a vulnerability (it limits emergency backup options).
Conclusion: A Utility at a Crossroads
CPS Energy stands at a pivotal moment. Its finances are stretched by post-storm debt, infrastructure investment demands, and the capital costs of an energy transition that can't be delayed. Its customers are stretched by rising bills and eroded trust. And now, its legal exposure is growing as the Preston Hollow explosion lawsuits work their way through the courts.
None of this means CPS Energy is failing in a categorical sense — it remains a fundamentally important institution that serves San Antonio well in most respects, most of the time. But the constellation of pressures it faces demands something more than incremental management. It requires honest accounting of infrastructure risk, transparent communication with customers, and investment decisions that prioritize safety over financial convenience.
For San Antonio residents, the lesson from Preston Hollow is immediate and practical: know your utility's emergency contacts, invest in basic home safety equipment, and don't assume that because a pipe has worked for decades, it will work tomorrow. For policymakers, the lesson is that deferred infrastructure investment is a debt that collects compound interest — and it isn't always paid in dollars.
The coming months will be telling. How CPS Energy responds to the litigation, what its infrastructure audits reveal, and whether it can chart a credible path to both financial stability and genuine safety reform will define the utility's relationship with San Antonio for years to come.
