Taylor, who is playing at Ally Pally for the final time, has never lost a semi-final there before and he ensured the same didn’t happen again as he cruised to a 6-1 win.
Lewis, who came through the preliminaries, started off strongly.
But after missing double 13, the Welshman was made to pay.
Taylor levelled proceedings and applied pressure on the 26-year-old.
Lewis continued to have opportunities and he could have gone two sets to one up, but Double 16 proved to be his undoing.
Taylor without ever hitting top gear, assumed full control.
The 16-times world champion produced a moment of magic in the seventh set when he pulled one leg back when he produced a 95 checkout with a pair of Double 19s.
Taylor averaged just over 100, but he’s through to another final.
He will face the winner of Michael van Gerwen or Rob Cross.
