CALGARY — A propellant in the Calgary Flames' surge to the top of the NHL's Western Conference is a power play with pop.

Calgary's man advantage was not a strength last season, when the Flames finished tied for third-last in the NHL in that department.

It took a few weeks for Calgary's power play to build steam under new coaches this season, but the Flames have scored a league-leading 12 goals with a man advantage so far in January.

Top-line centre Sean Monahan had potted three this month with Johnny Gaudreau, Elias Lindholm and Sam Bennett contributing two apiece.

With 42 goals from Calgary's power-play units in 50 games this season, the Flames are one away from matching their entire output of 2017-18.

"In the last month, both units have provided offence and scored, so that's been a big boost for us, and they've been timely goals also," Flames head coach Bill Peters said.

"A little competition between those two units is always healthy too."

Peters, in his first season behind Calgary's bench, assigned power-play management to assistant Geoff Ward, who also arrived last summer from the New Jersey Devils.

"Once we knew we had Wardo coming in to run our power play, I don't know if he spent any time looking at what was done here in the past," Peters said. "We talked about those types of philosophies and what we believe in. He looked at the skill sets of everybody and came up with what we're currently doing."

Calgary's power play ranked 13th in the NHL on Jan. 1 with a 21.1 per cent success rate. The Flames have since elevated that to 24.1 per cent, good for eighth in the league.

Monahan leads Calgary in power-play goals with 11, which puts him in a three-way tie for second in the NHL behind Boston's David Pastrnak and Tampa Bay's Brayden Point (13).

Gaudreau tops the Flames in power-play points with 22.

The Flames have averaged just under 3.5 power-play chances per game this season compared to 3.2 last season.

"I think this year, we're allowing ourselves to be on the power play more," Monahan said. "We're moving our feet more, which gives us more time on the power play by drawing penalties.

"When you're drawing penalties and you're getting yourself on the power play, you've got to get momentum from that. When you're out there that much on special teams, you've got to make something happen.

"We talk about it every day. Special teams are huge, especially at this point in the season moving forward. You've got to be confident when you go out there on the power play and you've got to expect to create momentum for yourself."

The Flames (32-13-5) are at home Tuesday to the Hurricanes (23-20-5) before the all-star break combined with a bye gives Calgary an eight-day hiatus.

Peters, who coached Carolina for four seasons before his arrival in Calgary, will face his former club for the first time.

"It'll be fun, it'll be good," Peters said. "I think they'll know what we're trying to do and I'll know what they're trying to do to a certain degree."

It's also the first game between the two clubs since Flames GM Brad Treliving sent defenceman Dougie Hamilton, forward Michael Ferland and prospect Adam Fox to Raleigh to get Lindholm and defenceman Noah Hanifin in June.

After musing to reporters following Monday's practice that he would probably go say hello to the Hurricanes he knew, Peters didn't have to wait long to make contact

Rod Brind'Amour, who was promoted from assistant to head coach after Peters' departure, waded through media to shake the Calgary's coach's hand.

After Carolina's 4-1 loss to the Ottawa Senators on Saturday, Brind'Amour threatened to come off the bench and out of retirement to play, which was a source of hilarity between him and Peters.

The former Hurricanes' captain retired in 2010 after a 20-year career.

"We watched some video today in case Roddy comes in and takes some faceoffs," Peters quipped.
