Texas passed a new law that lets ERCOT disconnect large non-critical loads during grid emergencies. The target group includes massive data centers and other high-demand sites. The state also set up programs that ask these sites to ramp down or switch to onsite backup power in tight conditions.
This policy shift signals a stressed grid and a rising outage risk. Businesses that depend on continuous power need a clear plan. Backup generators provide that plan.
Why Texas changed course
Texas demand is rising fast due to industrial growth, electrification, and data centers that support AI. ERCOT projects that peak demand may nearly double by 2030. Transmission congestion already limits power flows across the state. Price spikes and conservation alerts confirm the strain. These trends are not unique to Texas. National demand is climbing at a pace the country has not seen in decades.
The U.S. Department of Energy warns that blackout risk could rise by a factor of 100 by 2030 if the country fails to add firm capacity and improve operations. That warning underlines the need for local resilience at the facility level today.
What ERCOT’s backup plan includes
Key elements
-
Mandatory curtailment for very large loads. Loads at or above a defined threshold must accept disconnection during firm load shed events. The law also requires shutoff equipment as a condition of interconnection for new large loads.
- A voluntary demand program. Large users can agree to reduce load or run onsite generation during specified periods. The goal is to ease stress without shifting costs to residential customers.
- Interconnection and cost-sharing rules. New standards and fees seek to filter “phantom load” requests and align costs with those who drive them.
What this means in practice
The state wants critical services online during emergencies. Large non-critical loads will give way first. For operators of data centers and heavy industry, this makes onsite generation a core reliability tool, not a luxury. It also sets clear expectations for large projects entering the queue.
The business impact: risk, cost, and continuity
Who faces the highest risk
-
Data centers. These facilities sit at the front of the curtailment line. A forced outage can stop compute workloads, trigger SLA penalties, and create data integrity risk.
- Industrial and manufacturing sites. Plants with electric process loads can face cascading impacts from regional constraints. Any unplanned stop can waste materials and damage equipment.
- Hospitals, logistics, retail, and cold storage. Even short outages can endanger safety, spoil inventory, and disrupt revenue. These sectors need a clear fallback that starts within seconds.
Why the grid alone cannot carry the load
Transmission limits keep megawatts “stranded” away from load pockets at the wrong time. New lines take years. New plants take years. The gap is here today. Businesses need a near-term hedge that they control onsite. Backup generation provides that hedge.
Smarter operations help, but they do not replace backup
Software tools can raise transfer capacity on existing lines. Europe uses dynamic line ratings and hyperlocal weather models to push more power through the same wires when conditions allow. These tools help reduce curtailments and ease bottlenecks, but they do not eliminate emergency risk at a given facility. Onsite power remains the last line of defense.
Why backup generators are now essential in Texas
-
Policy reality. ERCOT can cut large non-critical loads in a crisis. Onsite power keeps your facility running when that call comes.
-
Operational control. You decide which loads to carry, for how long, and on which fuel.
-
Financial protection. You avoid shutdown costs, SLA hits, spoilage, and missed orders.
-
Program participation. With onsite generation, you can join voluntary demand programs without stopping core operations.
-
Resilience for supply chains. Your site stays online while others go dark, which protects contracts and customer trust.
How to build the right backup plan
Step 1: Identify your “must-run” loads
List life-safety systems, controls, servers, networks, refrigeration, and key process equipment. Define the hours of coverage you need. Add a margin for startup surges and future growth.
Step 2: Choose the generator path
Diesel offers high power density and fast start. Natural gas offers long fuel availability and lower emissions. Many sites use both: diesel for black-start and peak coverage, gas for long events. See the quick comparison below.
Step 3: Address fuel and runtime
For diesel, size onsite storage to cover your longest likely outage plus resupply time. For natural gas, confirm pipeline capacity and pressure under high-demand conditions. Consider dual-fuel or a mixed fleet for extra security.
Step 4: Integrate controls and transfer equipment
Use automatic transfer switches and clear runbooks. Test monthly under load. Keep spare parts and fluids onsite. Train staff on start, transfer, and cooldown procedures.
Step 5: Align with ERCOT programs
If you expect calls to curtail, set presets for partial load shed and generator carry. Document your sequence so staff can execute within minutes.
Diesel vs. Natural Gas Generators (At-a-Glance)
| Factor | Diesel Generator | Natural Gas Generator |
|---|---|---|
| Start Time | Fast, reliable black-start | Fast; depends on gas supply stability |
| Power Density | High kW in compact footprint | Lower kW per unit vs. diesel |
| Fuel Availability | Onsite tank; needs delivery | Continuous pipeline supply; check pressure |
| Runtime Strategy | Great for peak/no-gas sites | Great for long duration events |
| Emissions Profile | Higher; add aftertreatment as needed | Lower; useful for air permits |
| Maintenance | Regular fuel, fluids, and testing | Regular valves, plugs, and testing |

Sample generator strategies by facility type
Data centers
Pair a high-speed diesel fleet for black-start with natural gas units for long events. Add priority ATS on core suites and network gear. Test under live load with strict change control. Document run hours for contract reporting. This setup supports curtailment calls without downtime.
Manufacturing and process industry
Size for safe shutdown plus core lines. Use diesel where process loads require sharp response to step changes. Consider a gas unit to extend runtime through multi-day events. Protect controls, compressors, and pumps with dedicated circuits.
Healthcare and life safety
Follow code for life-safety branches. Use diesel for immediate pickup and test under NFPA supervision. Add gas for pharmacy, imaging, and HVAC continuity if pipeline service is dependable.
Cold storage and food service
Prioritize refrigeration, controls, and dock equipment. Diesel covers peak pulls from compressors. Monitor fuel quality and keep spare filters onsite.
FAQs
Will ERCOT disconnect smaller businesses?
The law focuses on very large loads. That said, smaller sites still face rolling outages and price spikes during tight conditions. A backup system protects against both.
Does the DOE warning affect Texas only?
No. The DOE report describes a national risk driven by load growth and plant retirements. Texas is a clear early case, but every region feels the pressure.
Are new gas plants and transmission lines coming?
Yes, but projects take years. Recent Texas efforts support new dispatchable capacity, yet the near-term gap remains. Onsite generation bridges that gap today.
