Energy, Data Centres & Infrastructure

Energy and infrastructure projects are major, long-term investments. They include many time-critical phases that need a proactive and comprehensive approach. Power plants, data centres, electrical lines or mining projects require many kinds of legal expertise over the course of their lifecycle—from environmental permits and impact assessments to subcontracting and financing agreements and potentially even stock exchange listing.

Energy and infrastructure projects can also have extensive impacts on the development of society. Renewable energy has become more affordable than fossil fuels even on a pure market basis. As the energy revolution proceeds, the challenges will be energy storage, electrical grid balancing and the diversification of energy production. Energy issues touch every company, as energy choices are a reflection of corporate responsibility.

In data centre projects, our multi-disciplinary team advises and works alongside leading data centre developers, investors, technology companies and energy providers to deliver successful outcomes in this rapidly expanding sector. 

Our experienced experts have advised developers and investors in Finland’s largest and most demanding projects. We can provide tailored solutions for the full range of legal issues in energy and infrastructure projects.

We acted as Finnish law legal adviser to the lenders and the export credit agencies in connection with the EUR 514.4 million green project financing for the development and construction of Easpring Finland New Materials Oy’s cathode active material (CAM) manufacturing plant in Kotka, Finland. The borrower, Easpring Finland New Materials Oy, is a joint venture owned by Beijing Easpring Material Technology, Finnish Minerals Group and LG Energy Solution. The financing was provided by six international commercial banks, with Société Générale acting as financial adviser and mandated lead arranger together with Natixis as co-mandated lead arranger, and DNB, ICBC, ING and Standard Chartered participating as lenders, with support from the export credit agencies Finnvera and Sinosure. The project represents a significant milestone for Finland and the European battery value chain by strengthening Europe’s domestic supply of cathode active materials, a key component in lithium-ion batteries for electric vehicles and energy storage applications. Once the first phase of the project is operational, the Kotka facility is expected to produce approximately 60,000 tonnes of cathode active material annually, making it one of the largest CAM production plants in Europe and supplying leading battery manufacturers across Europe.
