Project overview – why now?

► Crowned Ridge Wind, LLC elected to file the Crowned Ridge Wind Facility Permit

application in January 2019 for a number of reasons:

» Both Codington County and Grant County have completed the review process of the existing local ordinances and successfully codified new siting requirements for Wind Energy Systems » CRW has completed the necessary field surveys and micrositing of Project infrastructure and adopted changes to the Project site plan to ensure compliance with the newly codified county siting requirements for Wind Energy Systems » Land easements have been obtained for 99% of the Project’s proposed infrastructure » The South Dakota PUC’s application review process reflects a 6-month approval timeline which supports the Project’s proposed COD of December 2019

Operations overview

► The project will be monitored 24/7 from the Renewable Operations Control

Center by a SCADA system. In addition the site will be maintained and monitored locally from the O&M building by 12 wind technicians, technician site lead and a site manager

» Supervisory Control and Data Acquisition (SCADA) system collects real time data from wind farm and substation and feed information to controllers located in the turbine and substation » Controllers make automatic adjustments based on set points established for the safe, reliable and efficient operation of the site.

► The O&M building provides accommodation for the operations personnel who

are responsible to ensure that the facility is operated in accordance with North American Electric Reliability Corporation (NERC) standards
