It’s definitely something that hasn’t happened a lot since the Alex Ovechkin era started. Since his debut season in 2005-06 the Capitals have the second best power play in the NHL at 20.7%. That’s a tiny tick behind the San Jose Sharks league best 20.8% since the 2005-06 season. It’s above the Pittsburgh Penguins 20.2% which is third best since then.
This season, as a whole, the power play is pretty close to that 20.7% number. It’s currently 20.3% which is 14th best in the league. Hardly the worst the NHL has to offer. That’s top half of the league, not bad.
