METRO steht für klimafreundliche Energienutzung

METRO AG Position

METROs strategische Klimaschutzziel ist es, die spezifischen Treibhausgasemissionen bis 2030 um 50 % gegenüber dem Wert von 2011 zu reduzieren. Um dieses Ziel zu erreichen, spart METRO nicht nur Strom, Wärme und Trinkwasser und lässt die Nutzung von F-Gasen in Kühlanlagen auslaufen, sondern vertraut auch der Nutzung von erneuerbaren und emissionsarmen Technologien.

Photovoltaic systems

At locations where it is technically and legally possible and economically viable, we will increasingly rely on rooftop photovoltaic systems to use the electricity at the wholesale market or delivery depot.

 

So far, METRO Cash & Carry operates 14 of these PV plants with a capacity of approximately 5,300 kWpeak in Germany, Spain, Italy, Turkey and China. A photovoltaic system with a capacity of more than 1,000 kWpeak is planned on top of the zero-energy store in St. Pölten/Austria, which, in terms of figures, will be able to meet the entire energy needs of the new store. We are planning to add significant capacity of photovoltaic systems at METRO locations in different countries in the next few years for own consumption of the electricity produced.

 

Combined heat and power units

In the past few years, we have installed low-emission, high-efficiency combined heat and power units which generate the heat required in the wholesale store using natural gas and, as a by-product, produce electricity. Currently, six cogeneration units are being operated in Germany, including a gas turbine at the MCC wholesale store in Schwelm. Its heat is also used to cool goods via absorption units. Another combined heat and power unit was put into operation in Nizhny Novgorod/Russia on 1 September 2016; the next power plant will follow in the coming weeks in Ivanovo/Russia.

 

Solaranlage

Small wind turbines

We only add small wind turbines when the site-specific conditions allow it, such as at our green store in Dongguan/China which was opened in 2016. There, the LED car park lighting is operated autonomously by small 300-watt wind turbines and a photovoltaic cell, as well as a battery storage system. At the warehouse in Groß Gerau/Germany, we conducted trials with horizontal wind turbines. However, our expectations in terms of performance and maintenance of these systems were not met yet.

 

Solar chilling systems

In Rome/Italy and Antalya/Turkey we installed solar chilling systems. However, they required heavy maintenance. Since the roof surfaces can only be used once, we decided to give priority to photovoltaic power generation on the roofs.

 

Purchasing green power

Insofar as we can purchase renewable energy surpluses from neighbours, we have entered corresponding physical commitments. This includes electricity from a wind park in Bangalore/India, electricity from a biomass power plant in Reichenbach/Germany for a large warehouse or heat from a wood chip heating plant in Brunnthal/Germany.

Certified green electricity is only purchased by METRO if and for as long as it comes with a steering effect. Currently, we do not purchase green electricity for own consumption in Germany, because renewable energy is usually regulated by the EEG. However, we offer hydroelectric power produced in Germany to our Real customers. A steering effect is achieved via climate protection projects, such as rain forest reforestation projects in Ecuador. These projects are associated with every green electricity and green gas contract concluded.
