3 Export / non-export Generator Operation Intended Operation Transformer configuration Important: During the approvals process for commercial and technical reasons it is important that the intended generator operation is known. Eg if the application commences as a non-export installation and the intention changes to become an Export Generator then a completely new application will need to be submitted and the process recommenced, attracting new fees. Intended operation Export Non - Export Description Standby/Island Cogen grid connected Generation business Peak % Base Load % Network Support % Cogeneration % Annual Capacity Factor % Max output Max export to network Starts per annum Start/stop timing and characteristic Network Delta connection Customer side Delta Solid gnd Solid gnd Impedance gnd Impedance gnd (describe) (describe) Page 3 of 6 Version 1 4 Sep 2012
