Wolf sent a"certificate of ascertainment"to the national archivist in Washington with the slate of electors who support President-elect Biden and Vice-President-elect Kamala Harris.
Pennsylvania's 20 electors,a mix of elected Democrats,party activists and other staunch Biden backers,will meet in the state Capitol on December 14.
One of them,state Democratic Party chair Nancy Patton Mills,said she will also lead the Electoral College's meeting in Harrisburg next month.
Patton Mills said she was gratified that Pennsylvania was"the state that made it possible"for Biden to win.
Biden's win in the state,giving him its haul of 20 electoral votes,put him over the 270 needed and led The Associated Press to declare him the President-elect four days after election day. Biden has collected 306 overall electoral votes to Trump's 232.
The Pennsylvania results show Biden and Harris with 3.46 million votes,Trump and Vice-President Mike Pence with 3.38 million,and Libertarian Jo Jorgensen with 79,000.
