Decentralized Electricity
Generation is no longer only a few large plants. Rooftop solar, CHP, and batteries change power-system architecture.
Overview
Central plants still provide bulk energy and inertia in many grids. Distributed energy resources add local supply and new control problems: voltage rise, protection coordination, and market design. Decentralization is a spectrum, not an on/off switch.

Questions
How should we understand the decentralization of electricity production?
More small generators change power flows. They do not abolish physics or the need for a coordinated grid.
