FAQs

  • By switching to Ilmatar wind power, you are supporting a company that relies purely on wind. As we grow with the help of our well-informed and environmentally aware customers, we will be able to build more wind farms and produce more clean wind power and renewable energy for the needs of Finns. In this way, together we will increase the use of renewable energy and correspondingly reduce the use of fossil fuels.

    Ilmatar differs from other energy companies in that it produces and sells only 100% Finnish wind power.

    Most energy companies produce and/or sell more than electricity generated by wind power. Traditional energy companies also offer electricity produced by nuclear and coal power, among other things.

    In addition, all our wind farms are located in Finland and the wind power is produced and sold with the help of skilled Finnish labour.

    Ilmatar sells electricity only in Finland

  • Wind power is affordable. The current price of Ilmatar wind power can be found on our website.

    The prevailing price of wind power is affected by many different factors. These include e.g. weather conditions and the current prices of emission allowances.

    The onshore wind farms of Ilmatar Energy are currently one of the most cost-effective ways to generate electricity.

  • In addition to the address, each place of use of electricity is accompanied by a unique place of use code or a place of use number meaning the same thing. When you enter your address correctly on each line in our contract form, our system will automatically provide you with a place of use ID.

    If you wish, you can enter the place of use ID directly on the form. You will find it on your current electricity invoice. Using the place of use ID, our system automatically retrieves the wind power usage address on the form.

     

  • Electricity consumption varies according to different types of housing. For example, a 3-person household in a normally equipped apartment that has two to three rooms and a kitchen consumes about 2,400 kWh of electricity per year. Of the housing types, an electrically heated detached house consumes the most electricity, up to 18,500 kWh per year.

    Ilmatar Wind is a wind power contract valid until further notice with a 12-month price guarantee.  With it, you get affordable electricity for your home at a fixed price, always without surprise or hidden costs.

    A fixed-term contract is our customers’ most popular choice. The price of a fixed-term Ilmatar Wind12 or Ilmatar Wind24 electricity contract remains the same throughout the contract period.

    Ilmatar Wind Spot hourly is charged according to the hourly market price of wind power plus the commission of Ilmatar. This contract is especially worth choosing if you use electricity at times when electricity is particularly cheap, such as in summer or at night.

  • The entry into force of the electricity contract depends on your current contract situation. If you are moving, you can choose when you want wind power for your new apartment or address. However, the electricity contract does not normally enter into force immediately, but no earlier than two working days after the conclusion of the contract. If you plan to move within less than 5 days, please contact our customer service and we will secure the electricity for your new home even within the same day.

    If you are a customer of another energy company and want to switch from fossil fuels to 100% renewable wind power, the supply of electricity will start no earlier than 14 days after the conclusion of the new contract.

  • If you are a new customer, when making a contract you can choose whether you want an electric invoice by e-mail or a paper invoice. Both invoicing options are free, but we recommend the more environmentally friendly e-mail invoice.

    After receiving the first invoice, you can order the following invoices directly as e-invoices to your online bank. The payment period for our electricity invoices is always 14 days.

    When making a contract, you can choose whether you want an invoice every month or less often, every two or three months. If you would like to change your invoicing interval, please contact our customer service.

  • If your consumption is small and the total amount of the invoice is less than 8 euros, we will automatically transfer the invoiced consumption to the following month’s invoice. This is true even if you have selected the shortest monthly invoicing.

  • In Finland, the winter months are clearly windier than the summer months. Wind energy is produced most in the cold months, when energy consumption is also highest. Due to the higher air density, in subfreezing temperatures the wind also provides more energy than in warm conditions. The emphasis of the production of wind power is in the period from October to March, during which time about 60% of the annual wind electricity is generated.

  • The benefits of wind power are manifold. Wind power is clean, renewable, affordable and domestic. Ilmatar is an exceptional company worldwide, as it provides consumers with wind power alone. Our wind farms produce clean wind power all over Finland.

    The disadvantages of wind power, on the other hand, are related to emissions from e.g. the construction, transport and maintenance of the wind farms. According to a study carried out by the Technical University of Denmark (DTU), the total life cycle emissions (construction, operation and dismantling) of wind power are only 7 g CO2/kWh. Correspondingly, the life cycle emissions from electricity produced with coal are up to 820 g CO2/kWh.

  • In Finland and the EU, the origin of electricity is closely monitored. Wind power, like all renewable electricity, must have a so-called guarantee of origin in order to be sold as renewable electricity. Guarantees of origin are in circulation only to the extent that renewable electricity is actually produced, i.e. the wind power of Ilmatar, for example, cannot be sold more than it is produced.

    Electricity cannot yet be stored on a large scale. There is rarely completely calm in a large area, but there will still be times when wind power production falls short of its consumption. At such times, other renewable energy, such as hydropower, is used as the control force. On an annual basis, however, wind electricity is produced at least as much as it is sold.

  • A wind turbine requires a wind speed of 3.5–25 m/s to operate. There is almost always this much wind in Finland, especially at an altitude of more than 100 metres, where the poles of the wind turbines are located.

    According to a study conducted by the Finnish Meteorological Institute, during the 19-year reference period (2000-2018) there was no such windless period of at least one hour in Finland from November to January.

    However, if such a windless moment would occur, we will ensure with guarantees of origin that the electricity we sell has been produced with Finnish wind power. Electricity can come from multiple wind farms, ensuring that we are always able to supply electricity accordingly to our commitments. The guarantee of origin certificates are submitted to a register maintained by Fingrid, and operations are supervised by the Finnish Energy Agency.

  • The effects of built wind farms have been monitored extensively, and it has been found that e.g. noise effects or bird effects have been reliably assessed. In terms of bird effects, it has even been shown that migratory birds collide with wind farms less than estimated at the design stage. In terms of noise effects, the output noise level of the largest wind turbines today is about 104–107 decibels, but at the base of the power plant the sound level is only about 60 dB. According to the Government’s guideline value, the noise level of wind power in the outdoor areas of permanent and leisure settlements at night must not exceed 40 dB. This guideline zone is typically limited to a radius of 1 km from a modern wind farm. The noise level of wind turbines is regulated to a level about 5-10 dB lower than what is allowed for other industrial activities.

    In the vicinity of wind power areas, the sound pressure levels of broadband sound are typically lower than e.g. in traffic environments. Infrasound sound pressure levels have been found to be at or below the same level as in urban centres and higher than in natural environments.

    We operate in accordance with the guidelines set by the Government for regulating the outdoor noise level of wind power plants.

  • A guarantee of origin is proof that electricity has been generated by wind or other renewable energy sources.

    Ilmatar generates wind power in its own wind farms, sells it to consumers and companies, and then obtains a number of guarantees of origin equivalent to the wind power it sells from the Finnish grid company Fingrid.

    This way, our customers know that the electricity they use is pure renewable energy.

    It does not matter to the planet where carbon-free electricity is generated, as long as it is generated. The more customers use renewable electricity, the more it is produced.

    Ilmatar is the only electricity company in Finland that only produces and sells wind power.

  • Emissions trading is an arrangement in the European Union in which installations producing harmful emissions are required to own, for each unit of emissions they produce, a certain number of emissions allowances that these installations can buy and sell to each other. Emissions trading aims to limit harmful emissions in a cost-effective way.

    The Finnish National Emissions Trading Authority is the Energy Agency, whose tasks include permission, registration and control matters, as well as the auctioning of emission permits. The latest company-specific emission data for Finland is available here.

  • In the case of wind turbines, there is a lot of talk about infrasound, which means low sounds below 20 Hz. These are usually below the human hearing threshold and infrasound is constantly present in our environment even without wind power generation. The same physical laws apply to infrasound as to sounds above 20 Hz, i.e. it attenuates strongly as the distance increases. According to several international and Finnish peer-reviewed scientific studies, the audible or infrasound of wind turbines does not cause harm to health when the sound guidelines used for wind turbines in Finland are followed.

  • The main material of the wind turbine body is steel, which can be recycled efficiently. Materials that are challenging for recycling come from the wings of the power plant, which produce energy as they rotate. The wings are mainly made of fiberglass and various other composite materials. Glass and composite materials are durable, formable and lightweight, making them ideal for mobile products. In addition to wind turbines, they are also widely used in the marine and aerospace industries, among others.

    Fiberglass and composite are not classified as hazardous waste. Instead, they can be called cumbersome waste because they are challenging to recycle. Until now, these materials have mainly been disposed of in waste treatment areas, i.e. landfills, which is the worst solution in the waste hierarchy.

    When the fiberglass and other composite materials of the wings can be recycled, we can talk about a recycling rate of more than 90 per cent for the entire wind power plant. For wings alone, the recycling rate currently averages around 70-90%. Ilmatar Energy is committed to recycle its wind turbine’s wings.
