Contact details

I advise our clients in matters related to the environment, infrastructure and natural resources. I am particularly interested in projects related to renewable energy.

I graduated with a Master of Laws from the University of Helsinki in autumn 2022. While completing my studies, I worked at Castrén & Snellman for a year as a trainee. During this time, my interest and expertise in the field of environmental law grew and I decided to become an environmental lawyer.

During my studies, I also worked at other law firms, a software company and the police department.

BHP – Alliance agreement with Kingsrose Mining Limited
We acted as the Finnish legal advisor for BHP in connection with an exploration alliance agreement entered into between BHP and Kingsrose Mining Limited under which BHP (through a wholly owned subsidiary) will provide funding for regional mineral exploration across areas of interest in Finland. As part of the arrangement announced on 22 May 2024, BHP and Kingsrose entered into two exploration alliance agreements, focusing on nickel and copper exploration in specified regions in Finland and Norway. In Finland, the alliance agreement covers Kingsrose’s four exploration reservations at the Central Finland project in the Kotalahti Nickel Belt, a 400 kilometre long greenstone belt which hosts the past producing Hitura, Kotalahti and Enonkoski nickel mines. The alliances follow from Kingsrose’s successful participation in the BHP Xplor program, a global accelerator program targeting innovative, early-stage mineral exploration companies to find the critical resources necessary to drive the energy transition. BHP is the largest mining company in the world by market capitalisation, producing essential commodities through its assets, including iron ore, metallurgical coal, copper and nickel, and moving into potash.

Kemijoki – Major construction project for pumped storage hydropower plants that enable safe energy transition
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 advised S-Bank Plc in its issuance of a EUR 150 million Senior Non-Preferred Notes and on the tender offer of its EUR 150 million Senior Preferred MREL Eligible Notes maturing in 2026.

The purpose of the issue was to meet the minimum requirement for own funds and eligible liabilities (MREL) and to finance the bank’s activities.
