Skarta, builder of a clean future, developed a model for the calculation of CO2 emissions that relate to the infrastructure of wind farms

Emission-free wind power is a quick and effective way to reduce carbon dioxide emissions and to prevent climate change. However, as every kind of construction, also the construction of wind farms itself causes CO2 emissions. Skarta has developed a computational model, with the help of which different alternatives can be evaluated and the way to build a wind farm with as low emissions as possible can be chosen.

Energy production causes the largest amount of carbon dioxide emissions in the world. Wind power helps to reduce carbon footprint and to reach climate targets effectively, and it is the fastest-growing form of energy production in Europe. In Finland, wind farms are also built at an increasing pace.

Skarta is one of the most progressive and experienced wind power constructors of our country, and clean energy is at the core of its strategy and business operations. Skarta is the first company in Finland that has developed a method to calculate the carbon dioxide emissions of the Balance of Plant (BoP) construction of a wind farm. BoP stands for all infrastructure and electrical work within a wind park, including all construction with materials, except for wind turbines.

“We have specialized in BoP projects and participated in the construction of more than a hundred wind power plants. Based on our extensive experience, we developed a model to calculate the carbon footprint for the help of our clients. The pilot calculation has now been completed regarding the Norrskogen working site of EPV Windpower Ltd, where we have been constructing the infrastructure of 17 power plants this autumn. When completed, the annual production of the wind farm will be more than 300 000 megawatt hours of electricity”, says Anssi Koski, Director of BoP business line at Skarta.

In the pilot calculation, greenhouse gas emissions of all materials used in the BoP construction, equipment that is used for the earthworks, as well as all other appliances were unraveled as carbon dioxide equivalents. The calculation can be used to find out the CO2 amortization period of the wind farm. According to the pilot, it is 155 days regarding the infrastructure. In other words, the wind farm has compensated the emissions it has caused and starts to produce clean electricity in approximately five months from the end of the construction.

The pilot working site and the calculation have been carried out with market-based methods: CO2 emissions have not been used as a criterion for material, working method and policy selections.

“Therefore, the calculation is a good benchmark when planning the variables for the next projects, in which the target is to reduce carbon dioxide emissions”, Koski describes the continuation possibilities of the carbon footprint calculation.

EPV Windpower, owned by EPV Energy, is one of the leading operators in the industrial-scale wind power production in Finland. CEO Frans Liski says that in 2020 wind power constituted almost 26 percent of EPV’s energy production, and the target is to further increase its share in the group. When it comes to Skarta’s pilot, Liski says:

It is excellent that we can verify and follow the carbon footprint of our wind farms with Skarta’s calculation tool. Responsibility is the basis of our business and is seen in the operations, thinking and management of the company. In addition to the fact that EPV helps others to become emission-free with clean energy and heat, paying attention to the environmental aspects and carbon footprint in all our operations is very important for us.”

“Skarta already has the competence, equipment and measures with which BoP carbon dioxide emissions of the wind farms can be reduced approximately 40 percent. The carbon footprint can therefore be effectively minimized, if so wanted and decided”, Koski concludes.

Skarta Energy och Tohmajärvi kommun inleder samarbete – Planerar östra Finlands största energiprojekt13.9.2022 11:44:47 EEST | Tiedote

Skarta Energy Oy, del av SkartaNYAB, som genomför rena energilösningar, och Tohmajärvi kommun planerar sol- och vindparker i Tohmajärvi. För detta ändamål har bolaget och kommunen ingått en avsiktsförklaring genom vilket möjligheterna att bygga förnybar energi i Tohmajärvi kartläggs. Genom kartläggningarna utreds byggandet av flera sol- och vindparker samt områden som lämpar sig för byggandet av dem. Parkernas sammanlagda effekt ska vara 60 MW, och om projektet genomförs är detta det största energiprojektet i hela östra Finland. ”Den energi som produceras med hjälp av solkraft och vindkraft är helt förnybar och tillsammans stöder dessa energiformer varandra utmärkt. I det projekt som planeras utnyttjas också Skartas Vierivoima®-lösningar som stärker tillgången på ren energi till ett konkurrenskraftigt pris i regionen. Lösningen möjliggör också en snabb övergång till användning av väte i Tohmajärvi-området när behovet blir aktuellt”, säger Vikke Saarelainen, vice verkställande direktör

Skarta and Tohmajärvi municipality to begin cooperation – Eastern Finland’s largest energy project under planning13.9.2022 10:05:05 EEST | Press release

Clean energy solution provider Skarta Energy Oy and Tohmajärvi municipality are planning solar and wind farms for Tohmajärvi. For this purpose, the company and the municipality have signed a letter of intent to map out the possibilities of renewable energy construction in the Tohmajärvi area. The mapping investigates the construction of several solar and wind parks as well as the areas suitable for their construction. The combined total power of the parks would be 60 MW and, if realised, the project would be the largest energy project in Eastern Finland. “The energy produced by solar and wind power is completely renewable, and together these forms of energy support each other perfectly. The planned project also utilises Skarta’s Near Energy® solutions which increase the availability of competitively priced, clean energy in the area. The solution also enables the Tohmajärvi area to quickly transition to the use of hydrogen when the need becomes relevant,” says Vikke Saarelainen, Executi
