Reading the Tomakomai records
The registry contains 2 published records in Tomakomai. Announced projects, construction and operational facilities are distinguished, with dates and sources for each record.
MW values distinguish IT load, utility supply, facility, campus and planned maximum capacity. Records can cover buildings in the same campus, so their capacities are not simply summed. Municipality coordinates are not exact facility locations.
