Capacity, status, permit, grid-request and construction changes over the last three years, each with its source. A change means the same source reported a new value later; two sources disagreeing is not a change. Follow a facility, company, utility, state or ISO by email, or subscribe to the feed in any RSS reader.
Each change is tagged by evidence: ConfirmedBacked by a filing, deed, permit, interconnection-queue record, or a government or utility record. filing, deed, permit or grid recordAnnouncedStated by the company or reported in the press; not yet backed by a filing or grid record. company or press claimEst.Modeled, measured from satellite imagery, inferred from community mapping, or computed by this site.
