NVIDIA, Google, and Emerald AI have established the AI Energy Management Alliance (AEMA), aiming to transform AI data centers from "passive loads" into dispatchable grid resources. The alliance will promote flexible adjustments in data center power consumption based on real-time grid conditions and explore faster pathways for grid integration. It is estimated that enhancing the flexibility of data center power usage could unlock up to 100 gigawatts of existing grid capacity, alleviating the power constraints hindering AI expansion.

On Tuesday, local time,$Micron Technology (MU.US)$Sumit Sadana, Senior Advisor to the CEO and former Executive Vice President and Chief Commercial Officer, systematically outlined in an interview the supply-and-demand dynamics of the storage industry, shifts in business models, and the challenges of capacity expansion in the AI era.
Most notably, even as Micron is sharply increasing its capital expenditures and advancing roughly 20 capacity‑expansion projects worldwide, the current severe memory shortage is unlikely to ease in the near term. Sadana expects that meaningful additional supply will not begin ramping up until 2028; as for when supply and demand will rebalance, Micron currently "sees no clear timeline."

On September 16, according to The Information, Apple is developing an enterprise-grade server for AI applications, planned to be equipped with its self-developed M8 Ultra chip, and has already held talks with NVIDIA about adopting its NVLink Fusion interconnect technology. The product is currently expected to launch as early as 2029, targeting the AI inference market. This will mark Apple's first serious assessment of re-entering the enterprise server market since it discontinued the Xserve server in 2011.
