The Institute for Renewable Energy (IEO) Ltd. was founded in 2001. The core of the team consists of people who elaborated key legislative and strategic documents for the renewable energy sector in Poland i.e.: the Strategy for RES Development, the Implementation Programme for Green Electricity, and the Draft of the RE Act. Today, the above mentioned documents are foundation pillars for the RES energy policy and legislation in Poland. IEO also has an extensive experience in participating as an advisor (due-diligence, assumptions and concepts of technical solutions, functionality and utility programs, feasibility studies, business plans, terms of reference for a tender, supervision and construction monitoring) in the investment processes in the area of renewable energy implemented by the companies and government. IEO since 2009, conducts postgraduate studies "Investments in renewable energy sources", trainings and conferences in the field of technology, market economics and the law of renewable energy sources for national energy companies (eg. PGE, PKP Power Engineering), municipalities, financial companies (Alior Bank BGZ, ZBP) and foreign institutions (chambers of commerce in Germany and France, energy companies). In addition, as part of its work, the IEO completed a number of expert opinions commissioned by the Ministry of Economy, Ministry of Environment, Ministry of Regional Development and other governmental and commercial projects for business customers.
