Risks management discussed

  • Operational: Management expects the 336 MW under construction to be delivered within cost and schedule guidance; the release gives no detail on contingency. Source
  • Regulatory: Lake Hawkeye's potential is subject to permitting and site development, which management names as conditions. Source
  • External: Management said access to power has become the defining constraint on AI infrastructure development. Source

Earlier plans management reported on

  • Met: Management reports CB-3 delivery completed in early July, which satisfied the conditions for the Google credit support. Source
  • Met: The prior release said the acquisition remained subject to customary approvals including FERC; the current release reports FERC authorization received. Source
