The Historical Society will hold a short ceremony at 11am on Saturday September 30 at the Pioneers Wall entrance of the museum.
A few more pavers will be added to the pathway and two new plaques added to Pioneers Wall for families, Cobley and Thurtell.
Descendants of the Cobley family are planning a reunion on that day.
William Cobley moved with his family to Canowindra in 1901 from Victoria and lived at Edgecombe, Canowindra, where William specialised in lucerne cultivation.
As well as Edgecombe, he also had two other lucerne properties, Killarney and The Rivers.
Lucerne was profitable and with the boom in Canowindra following the coming of the railway in 1901, William Cobley built the landmark Cobley's Building in 1913 on the corner of Blatchford and Gaskill Streets.
To supply electricity to the new building he had a power generating plant installed in a shed at the back, making Canowindra the fourth town west of the Blue Mountains to have electricity.
Later, electricity was generated in the purpose-built concrete building, recently vacated by Farm Supplies in Ryall Street.
William Cobley was a generous benefactor of All Saints Church and the Soldiers Memorial Hospital in Canowindra.
Static Electricity Display at the Museum
As a tribute to William Cobley's role in bringing electricity to Canowindra, Audrey Farley, Museum Curator, is arranging a special display of early electrical items in the Historical Museum to be ready for Saturday September 30 and Sunday October 1 of Springfest.
Admission will be free on these two days.
All society publications will be on sale at discounted prices.
