HARC Models Texas Data-Center Growth as an Air-Quality and Grid-Access Constraint
Редакция ЦОД:Главное
Houston Advanced Research Center has released scenario modelling of how data-center expansion could affect Texas air pollution over the next five years. The analysis indicates that NOx emissions rise even under a grid-connected, renewables-supported supply case, while widespread on-site gas generation produces a far larger increase.
- HARC’s results are scenario modelling, not measured emissions from operating data centers.
- Texas is reported to have 26 GW of existing and under-construction data-center capacity and at least 288 planned projects.
- HARC projects a 35% increase in statewide NOx emissions by 2031 in its grid-connected scenario with on-site wind and solar.
- A conventional on-site gas-generation scenario produces an approximately 400% increase in NOx emissions in HARC’s modelling.
- ERCOT has received more than 500 large-load interconnection applications over two years, representing 439 GW of requested grid capacity.
HARC published its modelling on October 20, examining Texas air-pollution outcomes across three data-center demand forecasts and four power-supply scenarios over a five-year horizon. The work comes as Texas is reported to have 26 GW of existing and under-construction data-center capacity, alongside at least 288 planned projects.
In HARC’s cleaner “net-zero” scenario, data centers are connected to the grid and supported by on-site wind and solar generation. Despite that configuration, statewide NOx emissions are projected to increase by 35% by 2031. Under a conventional on-site natural-gas generation scenario, the projected NOx increase is approximately 400%.
The report highlights the infrastructure trade-off facing projects that cannot secure timely grid service. ERCOT has received more than 500 interconnection applications from large electricity consumers over the past two years, with large projects collectively seeking 439 GW of grid capacity. The reported wait for a data-center grid connection is three to five years. Developers are therefore considering or planning on-site generation, including gas-fired capacity, as an alternative to delayed interconnection.
According to the source, Texas Governor Greg Abbott has paused new data-center connections to the state grid pending individual review of project parameters. This adds a further project-level gate to a market already facing acute competition for interconnection capacity.
For operators, investors and developers, the modelling suggests that energy strategy is becoming integral to Texas site selection and delivery risk. If on-site gas generation becomes a common response to interconnection delays, projects could face more stringent environmental scrutiny, emissions-disclosure requirements and additional cost for cleaner, more reliable power configurations. Those outcomes remain contingent on which demand and supply scenarios ultimately materialise.
The findings underline how constrained grid interconnection can shift data-center energy strategies toward on-site gas generation, increasing environmental, permitting and reputational exposure. For AI data-center development in Texas, access to firm, lower-emission power and the timing of grid interconnection could become material constraints on delivery schedules and site selection.
