Helinä Teittinen

Associate, Master of Laws

I advise our clients on matters related to the environment, infrastructure and natural resources.

Prior to joining Castrén & Snellman, I worked at the Finnish Ministry of Transport and Communications on matters related to transport services. The experience increased my interest in environmental and energy matters as well as my understanding about the national and EU politics and the overall impact of the Green Transition on environmental legislation.

Alongside my studies, I worked in other Finnish business law firms, at the European Parliament and in several Finnish ministries. As part of my master’s studies, I spent one academic year at the Ludwig Maximilian University of Munich in Germany, where I gained a comprehensive understanding about the German legal system.

I am currently undertaking geography studies at the University of Helsinki, in order to understand the state of our environment more broadly than just from a merely legal perspective.

I also assist our clients in German.

We advised Excelerate Energy on the conclusion of a lease agreement with Gasgrid Finland Oy for the Floating Storage and Regasification Unit (FSRU) Exemplar. The Inkoo LNG terminal project will have a significant impact on securing the supply of gas to Finland and Estonia as imports of pipeline gas from Russia cease. The Exemplar is the first FSRU in Finland and the Inkoo LNG terminal project is legally unique. Moreover, the project, which is critical for Finland’s and the Baltics’ gas supply, was completed in an exceptionally short timeframe. Our experts assisted the company in a wide range of areas including contracts, energy legislation, licensing, labour law, taxation and structuring.

We are advising Kemijoki Oy as the company is exploring the possibility of building pumped storage hydropower plants as part of its existing production infrastructure in Northern Finland. The socially significant project enables safe energy transition and would have a significant role in mitigating climate change. The 200–600 MW pumped storage power plants explored by Kemijoki Oy would increase the regulating capacity of hydropower in Finland by up to 4,000 MW. The increase is exceptionally significant since Finland’s current hydropower capacity, which is mainly regulatable, is 3,100 MW. The scale of the project is also reflected in the fact that the nominal capacity of the company’s largest operating hydropower plant, Petäjäskoski hydropower plant, is 182 MW. The scale of the possible investment totals up to 3 billion euros. The production of weather-dependent wind and solar power will increase significantly in Finland. This requires ensuring sufficient production capacity that can be regulated, and hydropower is the most important form of such production. The overall generating capacity of pumped storage hydropower is on the rise in Europe and elsewhere in the world, reducing the need of fossil fuels. The pumped storage plant consists of two reservoirs that will help the plant to produce power when demand is high by running water through turbines down from the upper reservoir to the lower reservoir. When demand for electricity is low, the pumped storage plant will pump water back up into the upper reservoir.

We acted as the local legal advisor to OX2 in an arrangement whereby OX2 agreed with Ingka Investments, an investment company of the Swedish IKEA retail business, on the sale of a 49% stake in its three offshore wind projects in Finland. The three offshore wind projects, Halla, Laine and Tyrsky, are located in the Finnish Exclusive Economic Zone. The projects’ total annual production could amount to up to 29 TWh once operational, corresponding to more than one third of the electricity consumed in Finland in 2022. The aim is that the offshore wind projects start generating electricity by the turn of the 2030s. OX2 started developing the Halla and Laine offshore wind projects four years ago and was the first company to obtain exploration permits from the Finnish Government for its offshore wind projects. We have advised OX2 in the development and permitting of the offshore wind farm projects .

We advised Vattenfall in an arrangement whereby Vattenfall and Metsähallitus agreed on the development and construction of Finland’s first offshore wind farm in the open sea area. The offshore wind farm, with a planned nominal capacity of 1.3 GW, is planned to be constructed approximately 15 kilometres off the coast in the municipality of Korsnäs located in Ostrobothnia. The offshore wind farm is expected to be operational in the early 2030’s, and its annual production is estimated to be approximately 5,000 GWh, corresponding to the annual electricity consumption of more than two million apartment homes or the annual consumption of around 250,000 electricity heated individual houses in Finland. The estimated value of the investment is 2–3 billion euros. Finland has set the goal of being carbon neutral by 2035 and carbon negative soon after that. Metsähallitus plays a key role in achieving this goal given that they are responsible for managing the state-owned land and water areas in Finland. The offshore wind farm also supports Vattenfall’s strategy to reach its goal of enabling fossil-free living within one generation. Vattenfall is a leading European energy company. Vattenfall employs approximately 19,000 people and has operations mainly in Sweden, Germany, the Netherlands, Denmark and the UK. Vattenfall is owned by the Swedish state.
