CommonGrid: The open source registry of the US power grid

CommonGrid is an open-source registry of the United States power grid. It brings together data from every utility, operator, plant, and interconnection in the country. The system allows users to filter by state, segment, and ISO, and query by asset type, segment, and territory. It includes information on demand response, rebates, EV programs, VPP, and various rate structures.

The dataset covers all types of energy generation, including solar, wind, nuclear, gas, and hydro. Infrastructure data ranges from 69 kV to 765 kV, and spatial data is attributed to owners. CommonGrid also includes spatially queryable information on every public AC and DC station in the U.S., along with networks, plug standards, and power levels.

It provides access to wholesale market nodes, trading hubs, load zones, SUBLAPs, and generation pricing across 7 ISOs/RTOs. Substations are detailed with voltage class, owner, and interconnected assets. CommonGrid is built like a wiki, with every change documented with an author, source, and timestamp. The platform is open for contributions, with a small elected moderation team and a low-friction process for small fixes.

Structured for big changes, approved edits are recorded in the changelog. Anyone can propose changes, and trusted contributors are auto-approved on non-critical fields. Contested changes trigger a discussion thread on the entity. CommonGrid is committed to transparency, offering 60 requests per hour unauthenticated and 5,000 per hour with a free key.

Geo endpoints serve MVT tiles, and full database dumps are published weekly under ODbL. The platform serves researchers, regulators, developers, and utilities, fostering a shared understanding of the grid's structure.
