About The Duck Curve

The Duck Curve covers the electric side of the energy transition: power generation beyond fossil fuels, grid-scale and home energy storage, electric vehicles, and the policy that shapes all of it. The name comes from the grid operators' most famous chart: the duck-shaped curve that daily net load traces when solar floods the middle of the day. It is the emblem of a grid in transition, and of the problems this site exists to cover.

How we source

Every article is built on primary sources: the filing, docket, dataset, paper, or first-party announcement where the information originated, not the coverage that echoed it. Sources are cited alongside every article, linked in the text where each claim is made. When a document can't be independently reviewed, we say so. Analysis and outlook sections extrapolate only from cited material, and say what they extrapolate from.

Corrections

When we get something wrong, we fix the article and note the correction at the end of it. If you spot an error, tell us; the fastest route is @theduckcurve.

Follow

RSS (or any topic's feed from the footer), and @theduckcurve on X. Every article is also available as plain markdown by appending .md to its URL.
