A planning evidence database. Records describe publicly reported projects; they do not represent commissioned demand, confirmed grid connections or ElecTrace simulation results. Most map points show approximate localities.
Capacity is kept in separate IT, facility, grid, unresolved MW and MVA categories. Campus and phase claims may overlap. No cross-project capacity total is calculated. Read the definitions and scope →
