IREN Limited just cleared a meaningful hurdle in the race to plug massive data centers into the Texas power grid. The company’s 2GW Sweetwater Hub has been conditionally classified as Base Load within ERCOT’s Batch Zero interconnection screening process, a designation that treats the project as known demand rather than a speculative request sitting in queue.
For a company building out more than 5 GW of global data center capacity, getting two gigawatts recognized as credible load in the nation’s most energy-hungry grid operator’s system is a substantial win.
What Batch Zero actually means
ERCOT, the grid operator for most of Texas, is drowning in interconnection requests. Hundreds of gigawatts worth of large-load applications, predominantly from data centers, have piled up as AI infrastructure buildout accelerates across the state.
Batch Zero is ERCOT’s answer to that logjam. Rather than processing applications one by one, the framework groups credible projects together and studies their collective impact on the grid. Projects that earn Base Load classification are essentially acknowledged as real demand, not aspirational filings from developers who may never break ground.
