Infrastructure as well as auxiliary buildings and supporting buildings valued at EUR 400–500 million will be built at the Hanhikivi 1 construction site. See the video and photo gallery below to take a quick look at what is going on at the construction site.
At the moment, approximately 210 people are working at the construction site on any given day. The Sitemanager system includes 588 companies, of which 543 are Finnish. Over 2,700 people have passed the site access training.
Construction of the nuclear power plant will start once Fennovoima has been granted a construction license for the plant. The nuclear power plant consists of a reactor building, a turbine building, a control room building, and fuel buildings, among others. The highest number of people involved in the construction of the nuclear power plant at a time will be around 4,000.

Hanhikivi 1 power line project proceeds
Main lines between the future nuclear power plant and the national grid will be built in Fennovoima’s Hanhikivi 1 power line project. When considering all phases, the transmission line project will take some 8–10 years. Electrical energy produced by the future nuclear power plant will be transmitted to the grid via the power lines.
Two parallel 400 kV transmission lines will be built between the Hanhikivi peninsula and a new transformer substation to be built at Hanhela in the municipality of Pyhäjoki. Two parallel 110 kV transmission lines will be built between the Hanhikivi peninsula and a new substation to be built at Valkeus in the municipality of Pyhäjoki. The total length of the 400 kV power lines to be built will be some 21 kilometers and the total length of the 100 kV power lines will be some 19 kilometers. The power line route has been selected based on an environmental impact assessment report.
Fennovoima submitted expropriation and advance take-over application to the Ministry of Economic Affairs and Employment in February 2019. The company sent letters to the local landowners on the filing of the expropriation permit application. The Government will grant the permit on the basis of a proposal by the Ministry of Economic Affairs and Employment. Usually, the processing of expropriation permit takes from six to twelve months.
Agreements between Fennovoima and the landowners on the use of the land areas cover more than 90% of the properties along the transmission line route. The Ministry of Economic Affairs and Employment will request opinions from the landowners who have not signed an agreement with Fennovoima.
The right of use of the properties along the transmission line route will be reduced. Fennovoima will pay compensation to be determined by a expropriation committee for land areas is question. Fennovoima will receive a limited right to use the transmission line route for the construction, operation, maintenance and renewal of the transmission lines. The landowners will still own the land areas.
The construction schedule for the transmission lines follows the schedule of the nuclear power plant project. According to the plan, the transmission lines will be built between 2020 and 2026 in such a manner that the 110 kV transmission lines will be commissioned in 2024–2025 and the 400 kV transmission lines in 2025–2026.
Once complete, Hanhikivi 1 will produce Finnish emission-free electricity at a stable price for at least 60 years.
Event for neighbors of the Hanhikivi 1 construction site and residents of the area on Tuesday, November 20, 2018
You are welcome to receive more information and discuss wintertime activities at the Hanhikivi 1 construction site at the Fennovoima training building on Tuesday, November 20, from 6 pm to 8 pm. Coffee will be served starting at 5:30 pm.The event is meant for neighbors of the Hanhikivi 1 construction site and residents of the area. The presentation will be given in Finnish.
Please enroll for the event by November 19: [email protected] or Kati Mehtomaa, tel. +358 20 757 8581.
At the event, Fennovoima’s Construction Director Jouni Sipiläinen, Site Environmental Manager Heidi Karjalainen, and Kala- ja vesitutkimus Oy’s CEO Sauli Vatanen will tell about the work at the construction site, environmental measurements, and the observation of habitats and species.
Water engineering of the port area continues to the south of Hanhikivi peninsula
BMGS Eesti filial will continue the dredging and water engineering works of the port and the cooling water intake channel and backup intake channel that were started by Terramare Oy in 2016. Terramare was able to complete more than 90% of the work last year. The work will start in September with dredging and excavation in the port area.
The dredging and excavation will cause local noise disturbance, as well as turbidity of the water in the working area and in its immediate vicinity. The dredging and excavation will be performed from the sea. Most of the dredging mass will be transferred to the mainland. The noise and the turbidity of the water will be monitored with continuously operating meters. Fishing in the construction areas and in their immediate vicinity will not be possible during the construction work.
Dredging will take place 24/7 as long as there is no ice cover. Underwater blasting may be performed between May 20 and October 10, taking into account the spawning period of fish. The work in the water areas will be performed in compliance with two water resources management permits granted by the Regional State Administrative Agency of Northern Finland.
BMGS Eesti filial is also in charge of the dredging and excavation of the cooling water discharge channel to the north of the Hanhikivi peninsula, which started in July.
Dredging and excavation starting to the north of the Hanhikivi peninsula
Dredging and excavation in front of the Hanhikivi peninsula will continue with a project stage that includes the construction of cooling water discharge structures and related protective embankments. The dredging and excavation connected to the cooling water discharge structures will start in July to the north of the Hanhikivi peninsula. The work will be performed by BMGS Eesti filial. The client is Titan-2.
The dredging and excavation will cause local noise disturbance, as well as turbidity of the water in the working area and in its immediate vicinity. Special attention to mitigating the noise impact, especially at night, has been paid in the work plans and risk assessments. According to the work plan, blasting will only be performed between 7:00 am and 10:00 pm. Most of the dredging and excavation will be performed from the mainland. The noise and turbidity of the water will be monitored with continuously operating meters. Fishing in the construction areas and in their immediate vicinity will not be possible during the construction work.
Dredging will take place 24/7 as long as there is no ice cover. Underwater blasting may be performed between May 20 and October 10, taking into account the spawning period of fish. The work in the water areas will be performed in compliance with the water resources management permits and environmental permits from the Regional State Administrative Agency of Northern Finland. The permit decisions include regulations on the performance of hydraulic engineering works, fishery fees, compensation to commercial fishermen and monitoring of the environment during construction, among other issues.
The cooling water discharge channel will be some 70 meters in width, 300 meters in length, and 3 meters in depth.
You can also opt to receive notifications about the construction site by email. To join the mailing list, please send an email to [email protected].
There is a movement restriction imposed by the Ministry of the Interior for the construction site on the Hanhikivi peninsula. The restricted area covers the land areas owned by Fennovoima and the water area limited by the construction site.
The restriction has been imposed in order to secure the operations and the property at the construction site, as well as to protect the people working there. Anybody violating the restriction can be ordered to pay a fine.
Aviation prohibition at the Hanhikivi peninsula
Aviation at the Hanhikivi peninsula construction site has been prohibited by a Government Decree. The aviation prohibition area covers the fenced-in construction site area on the Hanhikivi peninsula and the surrounding land and water areas in the immediate vicinity of the construction site. Aviation is only allowed if it is connected to the maintenance of the future Hanhikivi 1 nuclear power plant or specifically connected to its operation.
