Pre-Grid Commissioning for Renewables Alf Scambler Renewables Sector Development Manager

Main Grid Connection Delays Or Grid outages Solving project bottlenecks when grid delays occur. Simulation of Grid supply for commissioning of equipment. Can complete 99% of the commissioning. Can allow stage payments to be made. Keeps commissioning teams on site. Revenue generation for the developer as soon as grid is connected. O&M phase –Planned or unplanned grid outages, equipment can be kept healthy from the site HV network enabling maintenance, preservation of warranty and early resumption of power export to grid. 2
