The case commonly made

What supporters of the theme usually argue. Not our view.

  • Supporters point to data centers using large amounts of electricity that grids were not built to supply.
  • The case usually made is that generating plants and equipment take years to build, which limits how fast supply can grow.
  • Supporters argue that data center operators increasingly sign long-term power agreements with producers.

Risks commonly cited

What critics and cautious investors usually raise. Not our view.

  • Critics note that electricity prices and generation costs can change with fuel prices and regulation.
  • Risks often raised include delays in permits and grid connections that slow new projects.
  • Critics note that data center demand could grow more slowly than expected, leaving some capacity underused.
