Conflicts and open questions

  • Whether this is a data center is disputed: Google says it is an internal research facility without standard data center backup power; critics and outside experts say the load points to a data center.
  • Spectrum News described the draft CPUC terms as $600,000 per MW up front, up to about $150 million.
