irish Under-19 international Simon Power joined Norwich on 3rd January 2018 from University College Dublin. The 19 year oldwill play in the Under-23s Development Squad and signed an 18 month contract. He plays as a winger or forward and is blessed with "blistering pace".

Power began his youth career at Dublin club Cabinteely and, whilst still an Under 17 player, made his senior debut for them in August 2015. That solitary appearance was enough to prompt a move to UCD

On 8 August 2016, Simon made his UCD debut - ironically against Cabinteely - and he would make 3 substitute appearances for the senior team during the 2016 season. Simon's primary role was as a star player for the UCD Under 19 side, which in October 2016, secured the Irish U19 League title when they beat Galway 4-1, with Simon scoring a brace.

During the 2017 season, he was capped at both Under-18 and Under-19 level.

He is represented by Full Contact.

At the end of November 2018, it was reported that Power would be joining Dutch second-tier side FC Dordrecht on loan in January 2019. This became a reality after he signed a new two year contract with City. He made 12 appearances for Dordrecht, ten as substitute as he was hampered by injuries.

Power and Adam Idah played for Ireland's Under-21s at the Toulon tournament in June 2019, with Ireland reaching the semi-finals only to be defeated by Brazil. Power's form saw him linked with continental giants Borussia Dortmund, Lyon, Ajax and PSV Eindhoven.

On 4th July 2019, Simon joined Scottish Premiership side Ross County on a season long loan. This was cut short on 6th January 2020 with Power having made just four senior appearances for Ross County.

On 17th January 2020 he joined Kings Lynn Town on loan, making his debut the following debut in the National League North top of the table clash with York City which Lynn won 1-0 with Power winning the Man of the Match award. He made a total of 6 appearances before the season was curtailed due to Coronavirus.

On 5th August 2020, Power returned to Lynn on loan for the 2020/21 season which will be in the National League).

On 13th January 2021 it was reported that Power was poised to finish his King's Lynn Town loan and cut ties with Norwich City to step up his development with a move to League Two side Harrogate Town. He had scored two goals in 13 games during his second spell with the Linnets but has been offered a Football League chance by former Lynn defender Simon Weaver. Power is out of contract at Norwich at the end of this season, with the club holding the option for a further year, but it's understood he's being allowed to join Harrogate on a free - but with a sell-on clause in case he does kick on. Another League Two side, Cambridge United, as well as National League play-off hopefuls Bromley, are believed to have also been interested - with Lynn willing to match the wages the winger was being offered if he'd decided to see out his season-long loan. Power's transfer to Harrogate was finally confirmed on 18th January 2021.

Power was released by Harrogate on 12th May 2022. He returned to Ireland on 27th July 2022 signing for Shamrock Rovers.

On 20th December 2023, Power signed for Sligo Rovers who compete in the Irish Premier Division. He said “I am delighted to sign for the club, it’s good to get the deal done as it’s been in the works over the last few weeks. I am still young but I have a lot of games under my belt. My main attribute is pace and power and can get bums off seats and get the crowd going. I am looking forward to getting going now.”
