Slate Electrical Panel

1902 - 1930

Monday, March 10, 2014

The panel pictured on the left is from one of the Direct Current (DC) motor generators installed at Rossdale Power Plant before 1915. The material chosen for these panels needed to be not only durable, but also an excellant electrical insulator. Remarkably, at the time, the best choice for this application were panels cut from solid blocks of slate.

In the 1960s it was used to control DC power from a motor generator set, which was a back up for the generator exciters in the low pressure (LP) plant.

Edmonton Power Historical Foundation

Location:

We are located on the grounds of the Leduc West Antique Museum. Travel 5 km west of Leduc on Highway 39. Go north on Range Road 260 (Cohne Dale Road) for about 800 metres and the museum will be on your right. If you're coming from the west, Cohne Dale Road is 5km east of Highway 60.

Hours of operation 2025

Alas, the days are getting shorter, the shadows are getting longer, and too soon it will be winter. The Lesco Truck Show on September 20th was a HUGE success, but as the last visitors walked out our doors, the Edmonton Power Historical Foundation Museum sadly closed for 2025. Fear not, for we will open again in the spring of 2026 rested, refreshed and eager to show off our fine collection showcasing the history of electricity in Alberta.
But the year is not over yet! Every day during the month of December (except Christmas day), starting at 5:00 PM, the Leduc West Antique Society Park comes alive with millions of Christmas lights, and, for the big truck lovers, on Saturday December 13 the Leduc Country Christmas Convoy will parade from Blackjack's Roadhouse in Nisku to the LWAS site with horns blowing & diesels rumbling, each truck magnificantly decorated in hundreds of festive lights.
Mark your calendar and make sure you come out to see the lights. We'd LOVE to see you!
