According to RCMP, a SaskPower crew was restoring power to the line just outside the town of Wakaw, northeast of Saskatoon, at around 9:30 p.m. CST Saturday.
Police say the man was injured by the current in the line. He was transported to hospital in Rosthern where he was pronounced dead.
SaskPower confirmed the man's death in a news release Sunday morning.
"The biggest thing for us at SaskPower right now is our thoughts are with the family and that's our priority right now," SaskPower spokesperson Kristen Linklater told CBC News.
RCMP said their investigation is complete and foul play is not suspected.
Provincial Occupational Health and Safety officers and SaskPower's own safety officers were at the site of the incident Sunday to investigate.
