We have organized the necessary documents and company procedures step by step, from the notice of intent through technical review, power system impact assessment, contract signing, and power connection.
We prioritize verifying original sources from government and public agencies as well as operators. Duplicate entries from the same announcement are consolidated, and subsequent announcements regarding contracts, construction, and operations are recorded as change history. We distinguish between MOUs, plans, groundbreakings, completions, and operations; the number of posts does not represent the total number of data centers nationwide. When a new source document is confirmed, we add the actual text rather than simply updating the date.
