Prysmian has opened Finland's tallest building

The Prysmian Group has completed one of the largest investments in its history: a 185-metre-high cable tower, which is now Finland's tallest building, was erected on the site of the Pikkala plant in Kirkkonummi. The total volume of the investment is over 240 million euros.

The new vertical production line, which uses continuous vulcanization technology, makes it possible to produce up to one kilometer of submarine cable per day. Vertical production ensures better cable symmetry and quality, which is particularly important for high-voltage and extra-high-voltage cables.

The tower has been built primarily for the production of 525 kV submarine cables. These are important parts of the infrastructure that connect offshore wind farms to the mainland and support the goals of the European energy transition.

Innovation and new technologies

In addition to the increase in production capacity, Prysmian has also developed a new acoustic sensor that detects approaching threats, such as an anchor dragging on the seabed. The solution is based on the detection of sound waves propagating through an optical fiber. "Although the system does not prevent a potential attack, it simplifies the subsequent location of the fault," explains Raul Gil, Vice President of High Voltage Solutions at Prysmian.

New jobs and partners

Thanks to the plant's increased capacity, the number of employees will also grow. Nearly 100 new jobs are expected to be added to the current 500 employees over the next two years.

A step forward in Prysmian's global goals

The completion of the cable tower is part of the Prysmian Group's broader strategy, which aims to achieve net-zero emissions by 2035 and to increase the share of sustainable solutions to 55% by 2028. The new production capacity will significantly contribute to the construction of renewable energy connections throughout Europe and beyond, accelerating the transition to a carbon-neutral future.

The investment in the construction of the Pikkala tower is a part of a broader strategy. On the same day the cable tower was officially opened, the newest state-of-the-art cable-laying vessel, Prysmian Monna Lisa – the sister ship of the previous vessel, Leonardo da Vinci – was also launched. The 171-metre-long vessel is specially designed for the installation of submarine high-voltage cables, and its environmental footprint is the smallest in the industry. This strengthens Prysmian's position as a provider of innovative and sustainable solutions.

According to the company's CEO, Massimo Battaini, such investments are necessary not only to remain in the market but also to meet the broader goals of society. "We have also invested in Europe and in our common energy security and independence," he noted. "Without the transmission of electricity, there is no energy revolution, and as a global market leader, we are constantly working to meet the needs of our customers and society, while leaving a lasting positive legacy to the planet."
