What the sources establish

  • Microsoft proposes 15 more data centers in Mount Pleasant as part of two new campuses worth more than $13 billion, according to Wisconsin Public Radio. [1]
  • The Durand Avenue initial phase shows nine data centers and a 96,000-square-foot office on a 791-acre parcel, with a taxable value above $7.97 billion. [1]
  • The International Drive initial phase shows six data centers and a 74,000-square-foot office across about 530 acres, with a taxable value above $5.3 billion. [1]
  • The planning commission recommended approval as long as Microsoft meets several conditions, including a traffic analysis and state and local water-use rules. [1]
  • Both developments would sit in tax increment financing districts. The village estimates about $45 million a year from Durand and about $30 million a year from International Drive once district debts are paid. [1]
  • Microsoft has previously said its Mount Pleasant data centers would use up to 8.4 million gallons a year at full buildout, and a spokesperson said the expansion is expected to fit within that estimate. [1]
  • A Microsoft spokesperson said an estimate of the proposed data centers' energy use was not available at the time. [1]
  • If the plans are approved, the company may submit engineering plans, followed by building permit applications, before construction begins. [1]

Conflicts. Energy: a secondary summary, not opened here, gives 900 MW for the expansion with existing facilities. Microsoft said no energy estimate was available, so this page does not use that figure. Water: the spokesperson expects the expansion to fit the 8.4 million gallon estimate, and says additional local approval would be needed if it does not.
