DOE Retreat on Transmission Corridors Tests the Case for Building Ahead
DOE declined three proposed transmission corridors as its own study cites data center load growth, raising questions about how far ahead utilities should build.
The Department of Energy declined to designate three proposed transmission corridors for federal support, despite its own study identifying accelerating electricity demand from data centers and other sources as a major driver of future transmission needs. This decision highlights a central challenge for grid planning: utilities must decide whether to build transmission infrastructure early enough to support anticipated demand or risk the grid becoming a bottleneck after projects are committed, while also avoiding the cost of building too far ahead for demand that may not materialize. Texas's Competitive Renewable Energy Zones program offers a contrasting example of proactive transmission planning designed ahead of generation buildout, with data center developers later gravitating toward parts of that grid because of the infrastructure already in place. The tension between the DOE's transmission study findings and its decision not to designate specific corridors raises questions about how to balance the need for new transmission capacity with the requirements for federal designation of particular projects.

Google Unveils TPU 8i Max and TPU 8tx: A Dual-Chip TPU and a Confidential TPU
Google has added two new systems to its eighth-generation TPU lineup. TPU 8i Max targets massive context windows and rack density. TPU 8tx targets secure, confidential inference. Google TPU 8i Max is a dual-chip package built from 2 TPU 8i chips. Both arrive alongside TPU 8t and TPU 8i, announced in April. TL;DR Size: TPU 8i Max = 2 TPU 8i chips in 1 package. TPU 8tx = TPU 8t silicon plus 5th Gen AMD EPYC hosts. Runs on: Google Cloud TPU systems. Performance: 8i Max doubles TPU 8

IBM Announces IBM Quantum Nighthawk r3: A New Processor to Support 10k Quantum Operations on 520 Programmable Qubits
IBM has announced IBM Quantum Nighthawk r3, its next superconducting quantum processor. It is designed to run 10,000 quantum operations accurately across 520 programmable qubits. In 2027, IBM plans to link 2 r3 chips into a single 1,040-qubit system. For developers, the announcement is speed. The current Nighthawk r2 already runs workloads up to 19x faster than IBM’s earlier processors. TL;DR Size: Nighthawk r3: 520 programmable qubits, 2,034 physical qubits, 10 l-couplers. Nightha
Why the data center you dread might never even be built
The data center boom is running into serious real-world obstacles, from widespread local opposition and permitting delays to a scramble for electricity. Before those challenges even come into play, though, there’s a more basic problem: A lot of the projects being announced may never get built in the first place. With billions of dollars in AI infrastructure […]
