Reason For Revision

Based on a 2022 Berkley study 94% of utility scale pv uses at least a single axis tracking system, so I agree to 6 acres  per MW for solar. We will not be collecting details on fixed tilt vs tracking at the time of IR submission. Looking at more data,  .06 acres per MW is reasonable for BESS Storage.  The guidelines provided cover all types of generation currently in the queue and as new technology emerges will reevaluate. Should a project far enough along to submit an IR for a generation type not currently listed, they will need to provide documentation showing the project has acquired sufficient space as would any project suggesting they need less than what is listed.
