Two West Texas sites alone could generate over 10 gigawatts and, per regulatory filings, emit as much as 45 million metric tons of CO2 equivalent annually
Decision Focus
A Bloomberg News analysis published in August 2026, drawing on BloombergNEF tracking data, found that 99 proposed natural gas plants built specifically for US data centers could emit approximately 318 million metric tons of CO2 annually at industry-standard utilization rates. Against the 1,485 million metric tons the entire US electric power sector emitted last year, per Energy Information Administration data, that single slice of behind-the-meter infrastructure represents a potential 20% uplift in US power sector emissions. The operational signal for Global Heads of Data Center Energy is direct: the interconnection bottleneck has pushed developers toward an energy sourcing path that is accumulating faster than Scope 2 accounting and climate commitments were designed to handle.
90-Second Brief
In recent days, bloombergNEF is tracking 126 gigawatts of planned on-site gas generation capacity across 22 states, with more than a third concentrated in Texas. Projects linked to Amazon and Microsoft are among the largest. Two West Texas sites alone could generate over 10 gigawatts and, per regulatory filings, emit as much as 45 million metric tons of CO2 equivalent annually. The growth engine is grid access failure: yearslong interconnection delays and moratoriums on new grid project approvals are leaving developers with behind-the-meter generation as the fastest viable path to power.
What Is Really Happening?
The root cause is not appetite for carbon. It is queue failure at scale. Interconnection backlogs across PJM, ERCOT, and other organized markets have created a structural gap between when a data center can be built and when it can receive grid power. Behind-the-meter gas plants are permitted and constructed without utility or ISO approval, bypassing the timeline bottleneck entirely.
That regulatory arbitrage is now generating capital flows the grid governance system was not designed to price or constrain. Single-cycle gas turbines—the most common configuration in the current build pipeline according to the Bloomberg analysis—are being specified over more efficient combined-cycle alternatives specifically because combined-cycle turbines face a yearslong backlog of their own. Expediency is compounding emissions intensity: the fastest path to power is also the dirtiest per megawatt-hour.
The concentration in Texas reflects regulatory history as much as geography. A historically permissive siting environment and deep oil-and-gas infrastructure made West Texas the lowest-friction market for rapid capacity deployment. Texas Governor Greg Abbott’s announcement of a pause on data center approvals signals that even the most accommodating jurisdiction is beginning to recalibrate—introducing a new layer of siting uncertainty at exactly the moment when developers have the most capital committed to the region.
Why It Matters for Global Heads of Data Center Energy
Your Scope 2 accounting framework was built around grid-delivered electricity and matched RECs or CFE instruments. Behind-the-meter gas generation is Scope 1, directly attributable to your operations regardless of any renewable energy certificate strategy you have in place. If a significant share of your capacity roadmap depends on sites powered by on-site gas plants—whether owned, leased, or contracted through a developer—those emissions land on your balance sheet and your CDP disclosure, not on a utility’s avoided emissions calculation.
The sustainability exposure runs in both directions. Companies that committed to 24/7 carbon-free energy matching face a structural incompatibility with single-cycle gas as a baseload source: no volume of RECs offsets real-time fossil combustion under additionality-based accounting. At the same time, walking away from gas-backed sites may mean forgoing the only near-term path to the compute capacity your organization has already committed to deliver. That is a board-level tension, not a procurement-level one, and it needs to be named before a regulatory filing or investigative report does it for you.
There is also a counterparty risk dimension. Developers marketing AI-ready campuses powered by dedicated gas generation will vary substantially in how they characterize and report those emissions. Before executing lease or offtake agreements at gas-backed sites, the emissions accounting methodology your counterparty intends to use—and whether it aligns with your own sustainability reporting framework—is a material due diligence question.
Forward View
Three fronts are worth active monitoring. First, state-level siting regulation is in motion. Texas has already signaled a pause; other states with high data center density may follow with disclosure or approval requirements for behind-the-meter generation, particularly as the 20% emissions figure becomes a reference point in policy discussions. Second, the combined-cycle turbine backlog has not resolved. If lead times for more efficient equipment shorten materially, the economics of single-cycle gas become less compelling and some planned plants may shift configuration or stall. Third, ISO and FERC attention to behind-the-meter loads is increasing. Projects that bypass grid interconnection today may face retroactive reliability or emissions scrutiny as the total installed base grows large enough to attract regulatory action.
What Is Still Uncertain
The 99 plants tracked represent proposed, not permitted or constructed, capacity. How many will proceed to operation is not confirmed; the Bloomberg analysis itself acknowledges phantom projects and long-shot pitches in the pipeline. Emissions estimates are modeled against utilization assumptions, not measured outputs, and will vary with actual runtime and fuel efficiency. Neither Amazon nor Microsoft has disclosed a specific mechanism for reconciling gas-sourced operations with existing net-zero commitments, leaving the compatibility question open. The Texas approval pause has not been defined in scope or duration, so its effect on in-flight projects remains unclear.
One Question for Your Team
Of the sites currently in your development or lease pipeline, how many are planned to receive power from dedicated on-site gas generation—and what is your current Scope 1 accounting and disclosure plan for those facilities before they come online?
