Clearing vegetation increases biodiversity

Regular vegetation management around transmission lines improves
electrical safety and transmission reliability and also maintains vital open habitats for many animal and plant species.

Gigantic green steel project

Blastr Green Steel, a Norwegian entity, is planning a low-carbon steel mill in Inkoo, where it plans to produce steel with significantly lower carbon dioxide emissions than conventional production.

Preserving nature and maintaining the main grid

Fingrid’s main grid comprises more
than 14,000 kilometres of transmission lines. When the lines undergo maintenance, Fingrid strives to preserve natural values. In some cases, it is even beneficial to biodiversity.

Environment

Safeguarding biodiversity

Fingrid trains its contractors to identify harmful invasive alien species, limit the spread of such species, and combat them correctly.

Environment

Biodegradable ester oil for transformers?

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.

Has the day come for industrial-scale solar power?

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.

Research data on the use of concrete from demolition

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.

Environment

Life beneath transmission lines

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.
