Finland has the World’s Most Energy-Saving Supermarket – Half of the Energy it Consumes is Solar in Origin

The world's most energy-efficient supermarket, which consumes only 40 percent of the energy of a normal grocery store, is located in Finland. A new solution helps the retailer save around 180,000 euros in energy costs. The technology is now ready for use on commercial premises in general.

”On a sunny day, half of all electricity consumed by the low-energy supermarket is coming from the solar panels installed on the roof,” says Project Manager and solar power plant designer Klaus Känsälä of VTT Technical Research Centre of Finland.

 In addition, energy use can be managed by levelling out consumption peaks on the power grid. Renewable solar energy even enables the occasional disconnection of the shop’s cold chain from grid electricity. For example, the mornings, when energy prices are low, are the best time to store kilowatts for later use.  

”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.
”If all grocery stores in the S Group chain consumed 240 kilowatt hours, their electricity consumption would halve,” says Känsälä. 

 The pilot supermarket in Oulu is part of S Group, whose stores use a total of around 1.1 terawatt-hours (TWh) of electricity per year, whereas the state railway company, VR, uses around 0.76 TWh on its trains. Total electricity consumption throughout Finland is around 85 TWh, of which S Group uses around 2%. If the same concept were introduced in all S Group grocery stores, this would have a major effect on Finland's energy balance.

The project is part of the larger VIRPA project and will end in April next year. In addition to VTT, the University of Oulu and, from the private sector, Fingrid, S Group, Rejlers, Jalecon, Jetitek, Green Energy Finland, Fidelix and Emtele are involved. The overall size of the project amounts to around a million euros.

 The next step will involve bringing more commercial premises into the project.

Ensuring a Smooth Transition from OPC CLASSIC to OPC UA

Now, more than ever, industrial firms need to make sense of vast quantities of data having a critical impact on their performance. To support the variety of applications necessary today, information must be delivered with context so it can be understood and used in various ways by a variety of people. Growing adoption of the Industrial Internet of Things (IIoT) and Industrie 4.0 is also driving requirements for open and secure connectivity between devices and edge-to-cloud solutions.

Is Your HMI/SCADA Network as Secure as You Think It Is?

Network security frequently makes the news, often when some new viral attack is discovered or, worse yet, is successful. HMI/SCADA networks can be as susceptible to these unlawful break-ins as any others, unless the proper precautions are taken. Many software and hardware vendors have made their own attempts to stay ahead of online criminals, while others have combined forces to thwart such attacks.
