Public Grid

Public Grid is a climate-tech company building a software layer on top of the existing electric grid so households can switch to renewable energy and find savings without hardware, paperwork, or gatekeeping. Its platform sits on top of a user's utility account, brokers bulk green-energy contracts, applies local incentives, and surfaces cleaner, cheaper options in one click. Founded in 2022 (originally as Cottage Energy) and based in New York City, Public Grid says it serves 25,000+ households and is backed by Redbud VC and Hamilton Ventures.
