Supermarket and airport go solar in Finland

Construction of the largest airport solar power plant in the Nordics is underway on the roof of Terminal 2 at Helsinki Airport.

The world’s most energy-saving supermarket is being piloted in Finland, while Finavia is speeding up its ambitious climate program and is about to open the largest airport solar power plant in the Nordics at Helsinki Airport.

The pilot supermarket, located in Oulu and part of the S Group, consumes only 40 per cent of the energy of a normal grocery store. A significant share of the energy it uses is solar in origin.

The supermarket also saves energy by levelling out consumption peaks on the grid. The new solution, developed under VTT leadership and ready for commercial use, is expected to save the retailer around 180 000 euros in energy costs.

“In this energy-saving pilot supermarket, annual electricity consumption totals 240 kWh per square metre, which is close to the consumption of a normal residence, whereas a normal grocery store consumes 600 kWh a year,” says Seppo Jakola, premises manager of the regional retail firm, Osuuskauppa Arina.

Meanwhile, Finavia is speeding up its ambitious climate program, which aims to reduce the carbon dioxide emissions caused by operations at all its 21 airports to zero by 2020.

Helsinki Airport will already meet the target later this year, when the largest airport solar power plant in the Nordics and one of the first in connection with an airport in Europe will begin to produce energy.

The use of renewable energy by vehicles operating at Helsinki Airport will also increase significantly, and buses used for customer traffic at the airport will begin to use fuel manufactured entirely from waste and residue in 2017.
