Process Coordinator, Asset Optimisation and Trading (AOT)


Amsterdam, the Netherlands

Working for Vattenfall since:


Name: Marije Nellenstain

What are your responsibilities within Vattenfall?

Asset Optimisation and Trading (AOT) is the commercial heart of Vattenfall's wholesale and sourcing activities. I work in the business unit Asset Optimisation which is situated between our generation units and the wholesale market, where commercial decisions are made almost every minute. I think this is one of the most dynamic areas within the energy industry, with a fast pace of new developments.

Within this area I am responsible for the analysis of new business and implementation into our processes. This is the case when a new wind farm is commissioned and we would like to sell the power on the wholesale market. I analyse what this new business implies, which changes are needed in our work and IT processes. I also make sure that these changes will be implemented. I do this in close cooperation with our internal stakeholders such as Production, Origination, Risk Management, Business Controlling, and IT.

I also provide the internal stakeholders with feedback about our processes and ensure process improvement if needed. Other parts of my job involve data analysis on results, and developing new concepts together with management.

What do you appreciate about working for Vattenfall?

I find it exciting to work for Vattenfall since the company has a central position in the dynamic energy industry and encounters new developments, such as the integration of renewables, new technologies and regulation.

I also really appreciate the international context in which I work in. The energy industry moves across borders, and so does my work. I am part of an international team, and I also cooperate with colleagues from our Hamburg and Berlin offices.

Before, I was a trainee in the Vattenfall International Trainee Programme. This programme offered me the opportunity to work in different parts of the organisation and it provided me with various seminars on personal development.

Today, in my current position at Vattenfall, I am still given many opportunities to focus on personal development which I appreciate.
