Colwyn Bay’s Eirias Park lost Conwy council close to £1m this last year.
The council has now drafted in a troubleshooter to help boost income and cut costs.
But it said the venue has been successful so far, bringing the town international media coverage, estimating the value of the exposure to be close to £500,000.
Cllr Graham Rees, the council’s cabinet member for tourism, marketing and leisure, said: “The vision for Parc Eirias is as a Regional Centre of Excellence for Sports and Events with a quality family leisure offer; it’s a key economic driver within the Bay Life Regeneration Programme.
“The figures relate to the whole Eirias site, including the valuable community resources such as Colwyn Leisure Centre, Tennis Centre, parkland and lake, as well as supporting all the activity at the stadium and barn.
“I fully support the plans for further developments at Eirias to bring more people and increase revenue opportunities, and the planned addition of the new 3G pitch will offer greater opportunities for local schools and clubs to make use of the facilities throughout the year.
“The facilities at Eirias are superb and we’re extremely proud that all these resources are available here in Conwy County Borough.”
Economic benefit to region
The figures were outlined in a report to Conwy County Council’s Principal Overview and Scrutiny Committee, although council officers believe the complex is of economic benefit to the region overall.
Eirias Park posted a deficit of £939,332 in 2015/2016 despite hosting superstar Elton John and pop band The Vamps in June 2016, attracting 20,000 paying fans.
The anticipated loss for the year was a little less than £778,000.
Eirias Events Centre, the arm of the business responsible for gigs and rugby internationals, was budgeted to lose £231,000 but lost more than a third of a million pounds (£367,866).
Colwyn Leisure Centre lost more than £517,000 - £10,000 more than budgeted - despite attracting more than 337,000 customers to the facility which employs 136 full, part-time and casual staff.
International exposure
The report to the council said: “Activities delivered at Eirias have brought regular local, national and international media exposure to Colwyn Bay, Conwy County and the North Wales region.
“It is estimated that the annual value of ‘just’ the TV exposure created for Colwyn Bay/Conwy, as a result of the events held at Eirias, is approximately £450k.”
The Tennis Centre and Cafe lost more than £50,000.
The report said a business manager had been seconded to the complex to help increase revenue and cut cost.
Economic benefits for the area from the Elton John/Vamps concert were estimated by the authority at around £350,000 and those from rugby activities in excess of £500,000.
The report also outlined £240,000 worth of funding secured for the “Health Precinct” at the site, part of the National Exercise Referral Scheme (NERS).
Projected losses for 2016/2017 have been set at £708,484, a year in which Lionel Ritchie pulled in 15,000 fans.
Under their agreement with the Welsh Rugby Union it also emerged the council will pay £380,000 over five years towards the cost of hosting U20 matches at Eirias Stadium.
