Texas Has More Than 470 GW of Data Center Grid Connection Requests. ERCOT Is Evolving With It.

Texas continues to attract major technology, manufacturing and infrastructure investment, and data centers are becoming an increasingly visible part of that growth.

The scale of proposed electricity demand associated with these developments has produced some extraordinary numbers. Reuters reported in September that more than 470 gigawatts (GW) of data-center projects were seeking connections to the Texas grid.

For perspective, ERCOT’s current annual peak-demand record is approximately 91 GW.

Those numbers make for an attention-grabbing comparison, but they also need an important qualification:

A grid connection request is not the same as confirmed future electricity demand.

Projects may change size, proceed in phases, add onsite generation, relocate, experience delays or ultimately not move forward.

That distinction is increasingly important because Texas is not simply watching electricity demand grow. ERCOT is developing a more structured process to verify large projects, study them together and better understand where future demand is most likely to materialize.

That may ultimately be the more important story.

Important context: The 470+ GW development pipeline should not be interpreted as a forecast that Texas will actually add 470 GW of new electricity demand.

Texas Is Moving Toward a More Structured Large-Load Process

The challenge created by very large electricity projects is fundamentally different from ordinary commercial growth.

A restaurant, dealership, warehouse or manufacturing facility may add electricity demand measured in hundreds of kilowatts or a few megawatts. A major data-center development can request hundreds of megawatts.

When many projects of that scale seek service at roughly the same time, studying each project only in isolation becomes increasingly inefficient.

In June, the Public Utility Commission of Texas approved ERCOT’s Batch Zero process for qualifying large loads of 75 MW and greater. Rather than evaluating only one project at a time, the framework allows ERCOT to study qualifying projects together, assess the broader picture of future electricity demand, allocate available grid capacity and identify transmission upgrades that may be required.

ERCOT described Batch Zero as the first batch process of its kind among U.S. independent system operators for assessing large electricity users.

The planning question therefore becomes broader than:

Can this individual project connect?

It increasingly becomes:

How do multiple very large projects fit into the Texas electricity system together? That is a meaningful evolution for a state experiencing rapid economic and electricity-demand growth.

September Brought Verification Into Focus

September moved that framework further from planning into implementation.

On September 3, ERCOT issued provisional Batch Zero classifications to transmission and distribution providers. Projects could be conditionally included subject to requirements such as completing verification or resolving technical deficiencies.

On September 9, ERCOT began issuing formal Batch Zero Verification Requests for Information to many large-load projects that had been conditionally included. ERCOT says the responses are being used to verify whether projects meet the requirements associated with their conditional classifications before the process advances.

ERCOT also launched a separate Data Center State and Community Impact RFI covering certain data-center developments of 25 MW or greater. The information requested includes grid dependence, onsite generation, water sources and consumption, cooling technologies and other project characteristics. Responses are currently due October 12, with ERCOT planning to work with the PUCT toward a report by December 10.

The result is a more detailed information base around some of the largest proposed electricity users in Texas.

MPN MARKET NOTE

The size of the request pipeline is important. The quality and maturity of the projects inside that pipeline may ultimately be even more important.

Why Verification Matters

Large-load planning depends heavily on the quality of information behind future-demand estimates.

A preliminary development concept requesting several hundred megawatts is different from a project that has secured financing, land, permits, equipment and a defined construction schedule. Treating every request as equally likely to become operational could provide an incomplete picture of future electricity demand.

Verification can help ERCOT and transmission providers better understand which projects are progressing, when they may require electricity and what infrastructure could be necessary to serve them.

That information can support decisions about available grid capacity, transmission development, interconnection timing, generation requirements, location-specific constraints and long-term demand forecasts.

The process cannot eliminate every uncertainty associated with large industrial development. But it can provide a clearer distinction between requested load and load that is increasingly likely to materialize.

MPN MARKET NOTE

The size of the request pipeline is important. The quality and maturity of the projects inside that pipeline may ultimately be even more important.

What Does 470+ GW Actually Tell Us?

The 470+ GW figure is useful because it demonstrates the extraordinary level of interest in developing data-center infrastructure in Texas.

It should not, however, be interpreted literally as more than 470 GW of electricity that ERCOT will soon need to supply.

ERCOT’s current yearly peak-demand record is 91,089 MW, set in July 2026, and ERCOT notes that recent records can change slightly through the settlement process.

The fact that connection requests greatly exceed current peak demand illustrates the scale of the development pipeline, not the amount of load certain to appear on the system.

Some projects may proceed substantially as proposed. Others may resize, develop in stages, add onsite generation or battery storage, move elsewhere, experience delays or never reach commercial operation.

Over time, one of the more informative statistics may therefore be:

How much of the proposed pipeline becomes verified, substantiated and ultimately energized?

That is one reason ERCOT’s September verification work is worth following.

Texas Growth Is Driving Changes Beyond Data Centers

The larger story is not simply about one industry.

Texas electricity demand continues to evolve alongside population growth, manufacturing investment, technology development and broader economic expansion.

At the same time, the power system is evolving as well.

Texas’ electricity story is not only about rising demand. ERCOT’s 2025 Annual Report shows total installed capacity of about 184.9 GW in 2025, while its 2030 resource snapshot includes approximately 284.5 GW of installed and planned capacity. ERCOT notes that the 2030 figure includes planned projects expected to enter service through 2030 that have reached specified interconnection milestones, along with certain Texas Energy Fund projects.

The composition of that growth is also changing. Compared with ERCOT’s 2025 capacity snapshot, the 2030 figures include roughly 47.1 GW more solar capacity, 33.0 GW more battery storage, 10.4 GW more wind and 9.1 GW more thermal generation. These are installed-capacity figures, however, and should not be interpreted as equivalent dependable output during the hours when electricity demand is highest.

That distinction is important. As Texas attracts new data centers, manufacturers and other large electricity users, the market is simultaneously adding new resources and changing the mix of technologies available to serve demand.

Generation is only one part of the response. Transmission infrastructure continues to develop, while distributed-energy technologies, battery systems and Virtual Power Plants are creating additional ways for resources and customer loads to respond to grid conditions.

The process used to evaluate some of the state’s largest prospective electricity customers is becoming more structured as well.

This is why large demand numbers should not be considered in isolation. Demand, generation, transmission, storage, customer flexibility and market rules evolve together.

What Does This Mean for Texas Businesses?

For most commercial electricity customers, Batch Zero will not determine tomorrow’s electricity rate.

A restaurant group, dealership, warehouse, car wash, office portfolio or mid-sized manufacturing facility uses only a fraction of the electricity associated with a major data-center development.

But large changes in expected electricity demand can still matter over the longer term because they can influence generation planning, transmission investment and expectations about the broader electricity market.

The key point for commercial customers is that:

470+ GW of proposed data-center connections does not translate directly into a prediction about future commercial electricity prices.

Commercial electricity offers are influenced by many factors, including forward wholesale electricity prices, natural-gas markets, generation availability, transmission conditions, location, weather expectations, contract start date, contract duration, supplier appetite, credit and the customer’s own electricity-use profile.

That is why MyPowerNegotiator would not look at a large-load headline and conclude that every Texas business should immediately lock into a long-term electricity contract.

The more useful question is:

How do current market conditions intersect with your business’s contract expiration, location, load profile and available supplier options?

That is where broad market information becomes useful commercial intelligence.

Your Business’s Own Load Still Matters

Even as the Texas electricity market becomes more sophisticated, one fundamental principle remains important:

How and when a business uses electricity can materially affect how that account is evaluated.

Two businesses can consume the same annual number of kilowatt-hours while having very different load profiles.

A business operating primarily during daytime hours can look different from one operating around the clock. A manufacturing facility running multiple shifts can look very different from an office building. A car wash, dealership, restaurant and warehouse can each have substantially different hourly electricity-use patterns.

This is why commercial electricity procurement should not begin and end with:

“What is the lowest cents-per-kWh rate?”

A more useful starting point can be:

“What does our actual electricity usage look like, and which contract structure fits it?”

As Texas demand, generation and infrastructure continue evolving, understanding the individual customer becomes even more important.

MPN COMMERCIAL NOTE

The market matters. Your load profile, contract timing and supplier options determine the decision.

What Should Commercial Electricity Customers Watch Next?

One of the first things worth watching is how much of the proposed large-load pipeline becomes verified. As ERCOT collects more information, the market should gain a clearer picture of which projects are progressing toward development.

Location will also matter. A concentration of large new loads in one area of Texas can create different transmission and infrastructure requirements than the same demand distributed across several regions.

Another important issue is the role of onsite generation, battery storage and load flexibility. Very large electricity users increasingly have options that can change how much electricity they require from the grid and when they require it.

Transmission development will remain important as well. As credible future demand becomes clearer, infrastructure planning can become increasingly targeted toward areas where load growth is most likely to emerge. These developments will help shape the Texas electricity market over the coming years.

The Bigger Picture

The extraordinary amount of proposed large-load development says something important about Texas:

Companies want to invest and grow here.

Rapid growth inevitably creates new planning requirements.

ERCOT’s evolving large-load process illustrates how the electricity market is adapting by adding verification, broader system-level studies and more detailed information about proposed projects.

The 470+ GW headline gets attention. But the more useful questions are what happens next:

Which projects move forward? Where will they locate? How much electricity will they ultimately require? What generation or storage will they bring with them? And how will the Texas electricity system continue evolving as that investment develops?

Those questions are worth following for anyone participating in the Texas electricity market.

For an individual commercial customer, however, the decision remains much closer to home.

When does your electricity contract expire?

How and when does your business use electricity?

Which contract structures are available for that load profile?

And how do competing supplier offers compare?

At MyPowerNegotiator, we analyze historical electricity usage and load patterns before evaluating commercial electricity options. We work with multiple electricity suppliers and power generators so businesses can compare competitive offers and contract structures rather than making a decision based solely on an advertised rate or broad market headline.
