Sun Mesa, Arizona

Navajo County, Arizona · north of Joseph City and Holbrook · APS territory

An EHV node on a live 345 kV and 500 kV backbone, delivering a anchor at first power, with a contractual path to behind the meter.

Position

The scale site in the portfolio. A retired 1.1 GW coal hub leaves a live double circuit 345 kV and 500 kV backbone in the ground, and generation, storage and load are studied at a single point of interconnection under Q609 and LP-00108, so power can reach the campus without waiting on transmission deliverability. Land is measured in thousands of hectares rather than parcels, which is what turns into a floor rather than a ceiling. A neighbouring algae farm takes the thermal offtake, so waste heat leaves as a value add to a partner already on site, and dry air at 1,707 m (5,600 ft) of elevation rejects the balance without water, over an aquifer the campus does not need to draw on.

Power and energization

Firm grid at the switchyard plus generation, storage and load studied at one point of interconnection. An interim 100 MW connection is stated from late 2027, and mobile transformer skids carry the anchor from there to the permanent switchyard connection in Q4 2028, so revenue begins before the campus completes.

Rent commences per phase on delivery of the applicable premises. Path to structured as a right of first offer on adjacent capacity. P2 is an intermediate step and does not appear as a cover milestone. P2 is the first generation tranche behind the interim connection. P3 adds the second block. The permanent switchyard connection lands Q4 2028 and the skids retire against it. P4 is 750 MW at the campus meter.

Apollo's commitment is contingent on a locked site and a locked customer, so the Anthropic offtake and this campus together are the trigger.

Risks and caveats

LivePower purchase agreement. Not executed. The PPA gates the microgrid integrator appointment and the utility's large load approval.
LiveInterconnection. The Phase 1 system impact study is complete and the Phase 2 facility study is running. No large load agreement is in place.
OpenStudied, not contracted. The under LP-00108 is a study result at the point of interconnection, not contracted capacity.
OpenGeothermal. Excluded from the firm path pending gradient data and a test well.
