IOSG: The Paradigm Shift of Power Flexibility, From Macro Assets to Distributed Intelligence Layer
Author: Benji Siem, IOSG
I. Introduction
This research begins with a simple observation: the power system is being asked to complete a task it was never designed to perform.
With the accelerating penetration of renewable energy, the comprehensive advancement of electrification, and the surge in AI-driven data center demand, the traditional model of "building more generation and transmission facilities to meet peak loads" is collapsing. Infrastructure construction cycles are too long, grid connection queues are severely backlogged, and capital intensity remains elevated.
Against this backdrop, flexibility—the ability to dynamically adjust supply and demand in real-time—has evolved from an auxiliary function to a core pillar of grid reliability. The supply of flexibility, which previously relied mainly on large industrial loads and peaking power plants, is transforming into a complex multi-tier market where distributed energy resources (DER), software platforms, and aggregators coordinate hundreds
