The objectives of transmission grid maintenance concern safety, transmission system security, and finances. The efficiency of maintenance has been measured on a regular basis in international benchmarking studies.

The maintenance of the transmission grid is decentralised to four geographical areas within the company's regional operations:

• Northern Finland - Oulu office
• Western Finland - Petäjävesi office
• Eastern Finland - Varkaus office
• Southern Finland - Hämeenlinna office

The regional units co-ordinate maintenance work in their respective areas, and control and supervise the implementation of maintenance for the transmission lines and substations. Fingrid's business model as a client for transmission system equipment and services is founded on the fair competitive bidding of the purchases and services. We comply with all regulations concerning the competitive bidding process and extend them to the entire supply chain.
