Groupama Stadium in Lyon moves towards energy self-sufficiency

At the Groupama Stadium in Lyon in November 2017.

Having suffered four defeats in the first nine games of Ligue 1, Olympique Lyonnais (OL) is a bad student in the French football championship standings. But there is one area where the club, which won seven championships in a row between 2002 and 2008, is at the forefront: energy sobriety.

Groupama Stadium, which was opened on January 9, 2016, is presented as a virtuous model in energy consumption. The OL stadium is seeing regular improvements that reduce its carbon footprint. The Rhone leaders thus launched the Plus 20 minus 20 project in September: they managed to increase overall electricity production by 20% while reducing consumption by 20%.

Starting in 2019, club leaders opted for photovoltaic panels lining the parking lots around the stadium to provide electricity. These panels, which were installed this summer, today provide 8 gigawatts per year and meet 80% of the stadium’s electricity needs.

Horizontal wind turbines

Lyon leaders are now planning to purchase batteries to store the energy produced by these solar panels. The medium-term goal is clear: to increase production by 20% to move towards energy self-sufficiency in the coming years.

By the end of 2023, OL plans to use the roof of the LDLC Arena, the neighboring room where Asvel’s professional basketball team plays, and the football training center to install new panels. Other projects are also being considered, such as installing horizontal wind turbines in city furniture.

Warming up and lighting are the two main electricity consumption items in sports. The club uses geothermal energy, a reclaimed process the temperature or coolness of the soil according to the seasons, geothermal energy, which is preferred to provide the right temperature in the common areas of the stadium – such as the halls or boxes – makes it possible to divide the annual electricity consumption into four.

Engineers from Lyon also optimize the minimum temperature at which grass can grow. An operation that will reduce the warming of the land by a few more degrees.

As part of the energy sobriety plan presented by the government on Thursday, October 6, football clubs are being invited to reduce the lighting time of the pitches from 30% in the evening to 50% for daytime games. The Professional Football League has instructed Ligue 1 and Ligue 2 clubs to reduce the lighting in their stadiums before and after matches this weekend.

lower the temperature

on September 16, in the columns ParisianAmélie Oudéa-Castéra, Minister of Sports and the Olympic and Paralympic Games, reminded of the need to switch to low consumption LED bulbs.

Even today, nearly half of major league clubs are equipped with energy-dense sodium lamps. Lyon switched to LEDs in 2017, eighteen months after the opening of the Groupama Stadium. “This technology allows you to vary the power before and after the match instead of staying at full power”Underlines Lyon stadium manager Xavier Pierrot.

For this winter, Rhone leaders also plan to lower the temperature of the clubhouse, or even cut off the hot water in the common areas.

It is constant efforts that bear fruit. Since its opening, the Lyon stadium has managed to reduce its electricity consumption by 5% each year. According to distributor Enedis, this translates to 500,000 kilowatt-hours savings, equivalent to the average annual electricity consumption of one hundred French households.
