A high-voltage transformer in the main grid may contain as much as 100 tonnes of mineral oil, which is used as an electrical insulator and cooling medium. The environmental risks associated with transformer oils are very unlikely to be realised, but it is still necessary to make contingencies for them.
Experts believe that technological advances and a strong electricity grid will pave the way for new solar power projects in Finland. At present, Finland’s largest solar power plants are fairly small by international comparison, mainly consisting of projects constructed to meet the needs of specific properties or companies.
The route of a planned transmission line may change if the environmental impact assessment (EIA) reveals significant natural assets. There is currently a backlog in EIA projects.
Finland is also beginning to notice the benefit of electric transport.
Significant quantities of demolition concrete arise on Fingrid’s worksites. In order to understand the environmental impacts of this, Suvi Ollikainen was commissioned to write her Master’s Thesis on the topic. The results of the research will be made available to all of Fingrid’s stakeholders.
Fingrid is constantly on the lookout for new ways to take advantage of transmission line rights-of-way. Organic collection areas and insect hotels are among the latest experiments.
The substation in the Virkkala area of Lohja is pioneering Fingrid’s substation renewal efforts – it is the first substation to operate without sulphur hexafluoride (SF6 dielectric gas) in its switchgear. The project is groundbreaking on an international scale, as it is Siemens Energy Europe’s largest delivery of SF6-free technology to date.
Although we have long been aware of the acceleration of climate change and its impact on biodiversity, we have only begun taking note of the economic impact in recent years.
Fingrid Current assembled a top team of experts to discuss the hottest industry themes in April 2021. The main topic: the power system of the future. Gathering a record audience online, the event addressed electricity consumption, production and infrastructure, with Fingrid CEO Jukka Ruusunen as the host.
