The real estate is usually purchased only after the following requirements are assured, and there are many: Local and regional power grid robustness which includes: ability to service long-term capacity commitments, whether the developer will need to invest in and build substations themselves, and the legality and availability for on-site power generation (natural gas or electric). All of those requirements generally come after an assessment of local and state government appetite and willingness to cut red tape for such deals and provide favorable environmental policy.
