Today, projects and project management are an indispensable part of the business of modern companies which want to achieve success on the market. The subject of research in this thesis is the GreenPOW project. The primary goal of this thesis is to present the GreenPOW project. The idea for starting the GreenPOW project came when researching how energy efficiency can be achieved on an agricultural property. Projects like GreenPOW are extremely important because they aim to stimulate changes in the way people obtain and consume energy on a daily basis. The importance of starting the GreenPOW project is reflected in the fact that it can raise awareness and demonstrate the possibilities of hybrid systems for electricity production. Taking into account everything stated in this paper, the project is very attractive and its realization is necessary. A high return on investment and a small initial capital ensure the desire to embark on the project. The potential net profit of 66.662,4 € at the end of the first year from the start of the project, which took into account the worst outcome of low turnover, provides proof of the enormous potential of this project and the company GreenPOW d.o.o. When it comes to the potential of the project, the potential for business, as well as for the growth and development of business, exists in the future, mostly thanks to access to numerous ways of financing, that is, incentives from Croatia and European funds when it comes to electricity production and achieving energy efficiency.
