Demand side management comprises the planning, implementation and monitoring of electric-utility activities designed to encourage consumers to modify their level and pattern of electricity usage (US EIA definition). DSM spans energy-efficiency programmes, load shifting, peak shaving, time-of-use tariffs and demand response — the latter being the event-driven, short-term subset of DSM.

DSM vs demand response distinction
Overview
What it means
Managing the demand side of the grid as a resource, so supply need not grow in lockstep with consumption.
How it is used
Utilities run DSM programmes to defer generation and grid investment, integrate variable renewables, and lower system costs; regulators evaluate programme cost-effectiveness.
Why it matters
As electrification and renewables grow, flexible and efficient demand is a decarbonisation resource comparable to new supply — and usually cheaper.

Review board
Comment on a specific line. Each reviewer stays separate until an editor accepts a merged draft.
Each person comments on the definition or overview in their own draft card, with role, evidence and suggested wording kept together.
AI can compare comments against the current text, flag conflicting claims, surface missing evidence and identify where reviewers agree.
An editor merges compatible suggestions into a draft change, checks sources, records disagreements and decides what can be published.
