CyrusOne's second Calpine-powered rural Texas play after Bosque-Whitney: a Freestone County campus co-located beside the ~1 GW gas-fired Freestone Energy Center, drawing 380 MW in phase one with a further 380 MW held exclusively. Classified hybrid, not behind-the-meter, the primary release has Calpine supplying grid connectivity alongside the power.
