  • Equinix Diesel Spill in Meadowlands Puts Data Center Backup Fuel in Focus

    Equinix Diesel Spill in Meadowlands Puts Data Center Backup Fuel in Focus

    TL;DR · 30-second read

    The Short Version

    About 5,000 gallons of diesel fuel leaked from a storage tank at a large computer facility in Secaucus, New Jersey. That is roughly half of what a fuel tanker truck carries. It ran into a small creek that feeds the Hackensack River.

    The facility belongs to Equinix, which rents space to companies that run websites and online services. Cleanup crews are vacuuming fuel out of the water. State officials say the fuel did not reach the river.

    It matters because buildings like this often store large amounts of fuel for emergency generators, and nearly 100 New Jersey towns have already banned new ones.

    About 5,000 gallons of diesel fuel spilled from a storage tank at the Equinix data center in Secaucus, New Jersey, and flowed into Anderson Creek, a tributary of the Hackensack River, Gothamist reported on September 14, 2026. That figure comes from the New Jersey Department of Environmental Protection (DEP). Equinix said the leak was detected on Friday evening, September 11. It has hired the environmental services contractor Clean Harbors to handle remediation.

    DEP spokesperson Larry Hajna said the creek is small and narrow where the spill occurred and that the fuel was contained before it reached the river. Crews are expected to work at the site for several days. Hackensack Riverkeeper Bill Sheehan and Secaucus Mayor Michael Gonnelli have both called for the state to pursue a natural resource damages claim against the company.

    Executive Summary

    A fuel-tank leak at one of the New York metro area’s long-established data center sites has become an environmental cleanup and a political flashpoint. Contractors placed a boom (a floating barrier) across Anderson Creek to hold the diesel in place, and vacuum trucks have been pulling a fuel-and-water mixture out for treatment and disposal offsite. Equinix said it will conduct a full investigation and is committed to resolving the situation quickly.

    The incident matters beyond Secaucus for two reasons. First, it shows a physical risk that rarely comes up in discussions of data center growth. Many facilities keep large volumes of diesel on site so that emergency generators can run during grid outages. As power availability tightens and operators lean harder on on-site backup, that fuel is a real environmental liability. Second, the spill lands in a state where close to 100 municipalities have enacted local bans on new data centers and activists are pressing the governor for a statewide moratorium.

    Local officials were measured about the facility’s history. Gonnelli said the Secaucus site had operated for 25 years without issues, and Sheehan acknowledged that data centers have been in the Meadowlands for decades without causing problems. The open questions are what caused this failure, how much fuel is recovered, and whether the state seeks penalties or restoration funding.

    The Diesel Behind the Cloud

    Data centers are usually described in terms of servers, fiber and electricity. Their resilience also depends on something far older: fuel. To stay online through a utility outage, most large facilities keep diesel generators, along with on-site storage tanks sized to run them for hours or days. Equinix has not said what the leaking tank supplied, but backup generation is the most common reason a data center stores diesel in quantity.

    That fuel is normally managed under spill-prevention rules. Typical safeguards include double-walled tanks, secondary containment berms, leak detection and regular inspections. Because roughly 5,000 gallons reached a creek, at least one of those layers did not hold. Whether the cause was a tank failure, a fueling or transfer error, damaged piping or a containment gap will determine whether this was an isolated equipment problem or a warning about practices across a fleet of aging sites.

    Grid Stress Raises the Stakes on Backup Power

    The industry’s appetite for power has grown quickly with AI workloads, and utilities in several regions have warned about constrained capacity. Generators exist to cover emergencies. But when grids run tight, operators may test them more often, keep larger fuel reserves, or run them during demand-response events, when utilities ask big users to cut grid consumption. Each of these puts more diesel on site and increases handling.

    Nothing reported so far ties this spill to increased generator use or to AI demand, and it would be unfair to draw that link without evidence. The broader point still holds for buyers and investors. The environmental risk in data center portfolios is not just carbon emissions or water use. It also includes the ordinary, local hazard of storing and moving large volumes of fuel near waterways, and that exposure grows as backup power becomes more central to operations.

    What a Damages Claim Could Mean

    Sheehan wants New Jersey to pursue a natural resource damages claim. That is a legal mechanism under which a polluter pays to restore harmed ecosystems, separate from cleanup costs or fines. He pointed to a 1994 barge spill that put 310,000 gallons of caustic soda into the Hackensack River, which he said led to dedicated funding for the restoration of Lincoln Park in Jersey City. Mayor Gonnelli said he supports that push. The DEP said it did not yet have information on potential fines or enforcement.

    Timing makes this more sensitive than a typical industrial spill. The Hackensack River was placed on the federal Superfund list, the program for the country’s most contaminated sites, in 2022, and a major cleanup is approaching. For Equinix, the direct financial exposure from remediating a contained spill is likely modest for a company of its size. The reputational and regulatory cost in a state actively debating limits on data centers could be harder to quantify.

    A Flashpoint in New Jersey’s Data Center Debate

    Opponents of data center expansion quickly cited the spill. Ben Dziobek of Climate Revolution Action Network argued that data center problems, including pollution, grid strain and higher electric bills, do not stop at municipal borders and warrant state action. Governor Mikie Sherrill’s office declined to comment and referred questions to the DEP.

    Every side’s claims deserve a fair test. This single incident, at a site local officials say ran cleanly for a quarter century, does not by itself show that data centers are environmentally unsafe. Nor does it settle the argument over electricity prices, which the spill does not bear on. At the same time, the industry’s assurances that its facilities are low-impact neighbors depend on safeguards like fuel containment actually working. Equinix’s investigation findings, and whether it shares them, will matter for more than one creek.

    Background

    Equinix is one of the world’s largest colocation data center operators. It rents secure space, power, cooling and network interconnection to enterprises, cloud providers and network carriers, and it trades on Nasdaq under the ticker EQIX. Its Secaucus facility sits in the New Jersey Meadowlands, a longtime hub for data centers serving the New York financial and media markets. Local officials say the site has operated there for about 25 years.

    The Meadowlands are a network of wetlands, creeks and tidal waterways feeding the Hackensack River, which was designated a federal Superfund site in 2022 after decades of industrial pollution. New Jersey has become a battleground over data center growth. Close to 100 municipalities have enacted local bans on new facilities, and advocacy groups are pressing for a statewide moratorium, citing pollution, grid strain and electricity costs.

  • DOE Orders Data Centers to Backup Power to Free Grid for AC

    DOE Orders Data Centers to Backup Power to Free Grid for AC

    The U.S. Department of Energy issued a directive on or around July 3, 2026 instructing data centers to switch to on-site backup generators during an active heat wave, so that grid electricity could be redirected to residential and commercial air conditioning demand.

    The action, first reported by CNN, applies during the peak-load emergency window and treats hyperscale and colocation facilities as flexible load that can be temporarily islanded from the public grid.

    Executive Summary

    Federal regulators rarely intervene directly in how private data centers source their power. This order does exactly that, framing backup generators — normally reserved for outages — as a demand-response tool the government can call on during a grid emergency.

    For an industry that has spent the past two years defending its rising share of national electricity consumption, the directive is a concrete signal that data-center load is now large enough to be actively managed by policymakers, not just utilities. It also raises immediate questions about emissions, fuel supply, wear on generator fleets, and who bears the incremental cost.

    The CNN report is short on operational specifics. What is clear is the precedent: in a heat-driven grid crunch, the federal government has publicly told data centers to burn their own fuel so households can keep the AC on.

    From Backup to Balancing Asset

    Data-center backup generators — typically diesel, occasionally natural gas — are designed as insurance against utility failure. Running them proactively to relieve the grid reframes them as a demand-response resource, a category more commonly filled by industrial curtailment contracts and battery storage. The DOE’s move effectively conscripts private infrastructure into a public reliability role during an emergency window, without (based on the reporting available) a pre-existing market mechanism to compensate that role.

    For operators, the economics are straightforward but uncomfortable: diesel fuel and generator hours are far more expensive per kilowatt-hour than grid power, and every runtime hour consumes maintenance life and emissions allowances. Whether those costs are reimbursed, absorbed, or passed to tenants under force-majeure or emergency-operations clauses in colocation contracts is not addressed in the source.

    Policy Signal for a Power-Constrained Industry

    The directive lands in the middle of an ongoing national debate over data-center power draw, particularly from AI training and inference workloads. Utility interconnection queues are years long in several regions, and multiple states are weighing tariffs and rate structures specific to large loads. An emergency order that pulls data centers off the grid on the hottest days does not solve those structural issues, but it does establish a template: when residential cooling and industrial compute compete for the same electrons, households come first.

    That template has implications well beyond one heat wave. Operators planning new sites will read this as evidence that federal and state authorities are willing to treat their facilities as interruptible when the public interest demands it, which strengthens the case for on-site generation, long-duration storage, and firm behind-the-meter power. It also gives ammunition to utilities and community groups arguing that new hyperscale campuses should arrive with dedicated generation, not just a grid connection.

    Environmental and Reliability Trade-offs

    Shifting large facilities to diesel or gas backup during a heat wave trades one problem for another. Peak summer conditions already coincide with elevated ground-level ozone; concentrated diesel runtime in data-center clusters — northern Virginia, Dallas, Phoenix, Santa Clara — could measurably worsen local air quality on precisely the days when it is most fragile. The source does not indicate whether the order includes air-quality carve-outs, geographic targeting, or emissions monitoring.

    Reliability is the other side of the ledger. Backup generators are tested regularly but not designed for sustained multi-hour or multi-day operation across an entire fleet. Fuel logistics, cooling of the generators themselves in extreme heat, and the risk of cascading failure if a facility loses backup mid-event are real engineering concerns. None of these are discussed in the reporting available, and they will determine whether the directive is remembered as a pragmatic success or a stress test that exposed hidden fragility.

    Background

    Data-center electricity demand has climbed sharply over the past several years as cloud computing and, more recently, AI training and inference workloads have expanded. Utilities in Virginia, Texas, Arizona, and the Pacific Northwest have publicly flagged multi-year interconnection queues for large loads, and several states have opened proceedings on tariffs and cost allocation specific to hyperscale facilities.

    At the same time, summer heat waves have repeatedly pushed regional grids to the edge of their reserve margins, prompting conservation appeals and, in some cases, rolling outages. The DOE has authority to intervene in electricity emergencies but historically uses it sparingly and mostly to keep specific generators running. A directive aimed at reducing data-center load is a notable inversion of that pattern.

  • 8-Agency Tank Gauge Alert Shows Why AI Data Center Backup Fuel Is a Cyber Asset

    8-Agency Tank Gauge Alert Shows Why AI Data Center Backup Fuel Is a Cyber Asset

    TL;DR · 30-second read

    The Short Version

    Eight US government agencies, including the National Security Agency, warned on June 3 that hackers are breaking into the electronic gauges that measure what is inside fuel storage tanks, and tampering with them.

    These gauges sit on tanks across energy, chemical, farming and transport sites. The same kind of gauge often watches the diesel that keeps a data center’s emergency generators running during a power cut.

    If a gauge reports the wrong amount of fuel, a backup plan can fail exactly when it is needed. The agencies are urging every operator to lock these devices down.

    On June 3, 2026, the National Security Agency said in a press release that it had joined the Cybersecurity and Infrastructure Security Agency (CISA) and six other federal agencies in publishing a fact sheet titled CISA and Partners Urge Hardening Automatic Tank Gauge Systems. Automatic tank gauges (ATGs) are networked devices that remotely monitor fuel and liquid levels, temperature and potential leaks in storage tanks.

    The agencies said unattributed threat actors have been compromising internet-exposed ATGs and then modifying them through command execution. The co-authors are CISA, the NSA, the FBI, the Department of Energy, the Environmental Protection Agency, the TSA, the Department of Transportation and the Department of Agriculture. The NSA recommended that all operational technology owners in national security systems, the Department of War, the defense industrial base, the federal government and US critical infrastructure sectors review and implement the fact sheet’s mitigations.

    Executive Summary

    Eight federal agencies have jointly flagged ongoing malicious activity against a device most people have never heard of: the automatic tank gauge, the electronic sensor-and-console unit that reports how much liquid is in a tank, how warm it is and whether it is leaking. The warning names energy, chemical, food and agriculture, and transportation as affected sectors, and describes attackers not just reading these devices but changing them.

    For data center operators, the relevance is direct even though the sector is not singled out. Every facility with diesel backup generators stores fuel on site, and the number that tells an operator how many hours of emergency runtime remain is typically produced by tank-monitoring equipment of exactly this kind. A warning that such equipment is being actively modified by outsiders turns generator fuel data from a facilities housekeeping item into something that belongs inside the security program.

    The broader lesson is about scope. As AI campuses scale up their on-site generation and fuel storage, the attack surface grows with it, and much of that surface is operational technology (OT), the industrial control equipment that runs physical plant rather than business IT.

    The Gauge Behind the Runtime Promise

    A data center’s resilience story usually runs in layers: utility power, then batteries in the uninterruptible power supply (UPS) to bridge the first seconds of an outage, then diesel generators to carry the load for hours or days. That last layer is only as good as the fuel behind it, and operators state their emergency runtime in hours of on-site fuel. The figure they rely on comes from tank monitoring, the level, temperature and leak readings the agencies say ATGs are built to provide.

    The agencies describe attackers compromising internet-exposed ATGs and then modifying them through command execution, meaning they issued commands that changed how the device behaves. Applied to a generator fuel system, the operational risks are straightforward to reason about: a gauge that overstates fuel can leave an operator believing it has a day of runtime when it has far less; one with suppressed leak alarms can let a spill go unnoticed; one that throws false alarms can trigger unnecessary emergency deliveries or shutdown procedures. None of those outcomes needs an attacker to touch the generator itself. The fuel reading is part of the power chain, and that is why it now has to be defended like one.

    That argument scales with AI. Large AI training and inference campuses draw far more power than traditional enterprise halls, and operators that back that load with diesel need correspondingly more generators and more stored fuel. More tanks mean more gauges, and every networked gauge is a device that has to be inventoried, patched or isolated.

    A Broad Coalition, a Broader Recommendation

    The makeup of the coalition says something about how the agencies view the problem. The EPA regulates fuel storage and leak detection, the Department of Energy covers the energy sector, the TSA and Department of Transportation cover pipelines and transport, and the Department of Agriculture covers farm fuel storage. Pairing them with the NSA, CISA and the FBI signals that the concern spans environmental, safety and national security lines at once.

    Data centers are not among the sectors the fact sheet names. But the NSA’s recommendation is deliberately wide: all OT owners and operators in national security systems, the Department of War, the defense industrial base, the federal government and US critical infrastructure. Facilities that host government workloads, defense contractors or critical services fall squarely inside that language, and colocation providers serving those customers will likely be asked about it.

    Where Security Programs Tend to Thin Out

    Tank gauges often sit in an organizational gap. They are frequently specified by the fuel system or generator contractor, maintained by facilities staff, and sometimes connected so that a fuel supplier or monitoring service can read them remotely. The network team may not know they exist, and the security team may never have scanned them. That is the pattern that leaves OT devices reachable from the internet, and it is the exposure the agencies describe.

    The practical response is unglamorous: find every gauge, confirm none is reachable from the public internet, place them behind segmented networks, review remote-access arrangements with vendors, and apply the fact sheet’s mitigations. Just as important, operators should keep an independent way to verify fuel levels, such as periodic manual measurement, so that a single compromised device cannot quietly rewrite the runtime assumption an entire backup plan depends on.

    The agencies have not attributed the activity, and the warning should be read for what it is: evidence of ongoing compromise and modification of exposed devices, not a claim that any data center has lost backup power. That measured reading is still enough to justify action, because the fix is cheap relative to the consequence.

    Background

    Automatic tank gauges have been standard equipment on fuel storage tanks for decades, in large part because they automate the leak detection that environmental rules require for stored fuel. Over time many gained network interfaces so that owners, fuel suppliers and service contractors could read them remotely, and security researchers have documented internet-reachable units for roughly a decade.

    CISA leads federal efforts to protect US critical infrastructure and frequently co-publishes guidance with the NSA, the FBI and sector-specific agencies. Data centers depend on the same class of equipment: diesel generators backed by on-site fuel tanks remain the dominant form of emergency power, and fuel monitoring is part of how operators plan how long they can run without the grid.
