CenterPoint Energy said it expects 14 GW of large load projects, mostly led by data centers, to move forward under Texas’ new ‘Batch Zero’ large-load interconnection process. Announced during its Q2 2026 earnings call, the utility anticipates this will support a 50% increase in system load by 2029 across the Houston area as demand from digital infrastructure accelerates capital commitments and grid expansion.

50% projected load growth by end of 2029
ERCOT’s new interconnection rules
The Electric Reliability Council of Texas (ERCOT) introduced updated rules for large load interconnection in June, in response to rapid demand growth and a queue that exceeds 400 GW. The first wave of projects to pass through this framework is termed ‘Batch Zero.’ Designed to prioritize strong customer commitments and technical readiness, the process aims to better align new grid capacity with proven end-user demand, especially from energy-intensive sectors like data centers and high-performance computing.
Batch Zero is a direct response to the rising prevalence of hyperscale and AI-driven data centers choosing Texas for abundant energy access and pro-infrastructure regulatory climate. The process requires projects to have completed, or be nearing completion of, key system studies and to show evidence of definite load commitments.
This more rigorous gating is intended to alleviate historical interconnection bottlenecks in ERCOT, which had led to uncertainty for both utilities and developers. The new framework positions Texas as a leading state for coordinated grid expansion, much needed as the digital economy drives a step-change in load growth.
Project status and commitments
According to CenterPoint, more than 17 GW of large load projects were submitted to the Batch Zero process, with 14 GW on track for eligibility as either base load or studied load. About 10 GW of these projects have obtained all required ERCOT studies and qualify for base load, while another 4 GW are awaiting completion of one remaining study.
CenterPoint highlighted the strength of demand through signed facility extension agreements and approximately $900 million in customer deposits and commitments. This level of contracted participation demonstrates solid long-term end-user buy-in, which underpins the capital investments required for system upgrades.
The company expects nearly all of the 14 GW to reach commercial operation by the end of 2030. This anticipated energization aligns with data center and digital infrastructure developers’ ramp schedules and signifies a new scale of utility-customer coordination for major grid assets in Texas.
Grid impact in Houston area
For the Houston-area portion of CenterPoint’s system, the 14 GW of new large load represents an increase of more than 65% from the utility’s current peak system demand of 21 GW. This extraordinary growth is driven chiefly by the rapid proliferation of data centers and other power-intensive digital infrastructure colocated near urban load centers and major fiber routes.
CenterPoint’s second quarter results and capital plan revisions reflect the company’s response to this demand. The 10-year capital investment plan grew by $1.2 billion, now totaling $66.7 billion through 2035. Utility officials anticipate that further near-term upgrades and expansion efforts will be necessary as projects move forward in successive interconnection batches beyond Batch Zero.
ERCOT and grid planners face mounting pressure to accelerate substation, transformer, and transmission line construction to ensure reliability. Transmission providers must also manage customer expectations regarding timelines and potential grid congestion as loads energize in concentrated clusters.
Financial outlook and customer savings
CenterPoint reported consolidated net income of $244 million in Q2 2026, up from $198 million the previous year. The utility estimates that over the next decade, residential and commercial customers will benefit from $5 billion in savings tied to efficiencies and system revenues offset by the increase in large loads.
These customer savings are partly a result of shared investment in grid upgrades, with industrial-scale facilities absorbing a significant portion of the upfront capital expenses. CenterPoint’s approach to collecting nearly $900 million in customer cash deposits reduces risk exposure for the utility and ratepayers, an important consideration given the volatility of data center industry build cycles.
The influx of large-load customers aligns CenterPoint with a nationwide trend in which utilities are collaborating closely with digital infrastructure developers to secure financing, ensure study completion, and lock in utility-scale offtake contracts for power and capacity.
What happens next in Batch Zero
With the Batch Zero process underway, the remaining 3 GW of submitted projects are still awaiting required ERCOT study approvals. As decisions are made over the coming quarters, the list of eligible projects may expand, or some facilities could be deferred to later batches pending regulatory approval and study outcomes.
For developers and investors, the most viable projects will be those with clear customer commitments, advanced grid studies, and secured financing. ERCOT’s system operators and utilities will continue to refine processes as they balance the influx of large loads against ongoing reliability and resource adequacy assessments.
Long-term, Batch Zero’s outcomes will inform future interconnection frameworks and set precedents for other RTOs and ISOs facing similar digital infrastructure-driven booms. The Texas model is likely to influence national practices for large-load prioritization, cost allocation, and study sequencing across the electric sector.
What this means for buyers
Institutional investors and data center developers should closely track the progress of CenterPoint’s ‘Batch Zero’ projects, as their advancement signals new opportunities and potential constraints in Texas’ grid interconnection landscape. The high volume of eligible load, substantial long-term contracts, and strategic customer deposits all reflect a maturing approach to large-scale digital infrastructure planning. As utilities require stronger upfront commitments and demonstrate willingness for co-funding, buyers should prioritize early-stage engagement and rigorous project validation. The evolution of ERCOT’s process provides a blueprint for other growth markets and signals higher standards for interconnection readiness nationwide.
