In September, Fingrid arranged a climate-themed week for its personnel. Elina Hiltunen, Futurist, and Riku Lumiaro, Biodiversity Expert, visited to talk about climate change as a trend, the loss of biodiversity, and what climate action will be required to mitigate and halt the change.
Fingrid is preparing to initiate a project to install 110-kilovolt GIS using a new insulation technology. The vision is for 2025, and all switchgear installed after this date will contain environmentally friendly insulating gases. Switchgear containing SF6 as an insulating gas will be systematically phased out.
The design of the main grid includes making preparations for a climate-neutral society in which the importance of electricity is constantly increasing. Over the coming decades, the emissions produced by generating electricity must be lowered, and electricity consumers must be offered the best opportunities to obtain clean electricity.
Energy companies have taken a serious approach to preparations for a carbon-neutral future. Vantaa Energy is seeking to stop using coal by autumn 2022, when the extension to its waste-to-energy plant is commissioned. This action is approximately seven years ahead of its time, as a Government decision calls for the prevention of coal as a fuel for electricity and heating in May 2029.
Sulphur hexafluoride gas (SF6) has been the primary insulating medium in high-voltage electrical switchgear and controlgear for 40 years. Fingrid prevents the potent greenhouse gas from escaping into the atmosphere by constantly monitoring the equipment where it is used.
