Two weeks ago, we at Halcyon hosted our first large in-person event on time and speed to power: the critical paths for companies building the energy infrastructure required to meet soaring demand for AI compute. It’s the right topic, at the right time, for the right industries: power generation and utilities on one end, and hyperscalers on another, with throughlines from infrastructure developers, capital allocators, grid hardware manufacturers, and EPCs connecting both sides.
To help address an “unprecedented” surge in power demand from AI, data centers, and industrial electrification, in October 2025, the Federal Energy Regulatory Commission (FERC) opened Docket RM26-4-000 regarding the interconnection of large loads to the interstate transmission system.
