The project was operated by the Hrvatska elektroprivreda (HEP) and it was presented as a reconstruction of the Plomin A Power Plant, even though its capacity is planned to be four times bigger than the previous one (125 MW).

[5] HEP defended by saying that unlike gas and oil, coal comes from politically stable countries, mainly OECD, thus the supply for this raw material can be easily assured.

The BAT represent the most advanced and efficient methods that aim to reduce to the maximum the emissions and the environmental damage caused by power plants.

Due to the necessity of additional energy sources, Ministry of Spatial Planning and Construction approved HEP's Environmental Impact Assessment of the project in the middle of June, 2012.

[9] The neighbor country, Slovenia was also consulted on the early age of planning of the Plomin C that was expected to have environmental impact not only on Croatia, but on the whole region.

[10] Hunton & Williams, a legal consultancy company, was hired by HEP to advise on international tender for the design, construction and operation of the power plant.

[12] RWE explained the decision by their current capital constraint, as well as adjustment of the company's strategy related to the composition of the European power plant portfolio.

[14] Zelena Akcija/Green Action sent an awareness letter to the four companies, informing them regarding the economic and environmental negative effects the project may have and the locals opposition against its construction.

The main reasons brought by the appealing party were the high CO2 emissions that will lead to worsening of the population health in the region as well as global warming effect and increased dependence on the imported coal.

[16] Prof.dr.sc Enco Tireli, a local expert, who worked for HEP for more than 20 years and was also construction manager for Plomin B, confirmed the fact that the project will not be profitable due to the additional payment for CO2 credits.

[17] Zelena Akcija and Green Istria invoked that the assessment done by the Ministry did not consider in depth all the implications of the project on the human health and wellbeing.

[16] The two associations stressed that “the consequences of such irresponsible approach will be supported by the local population, and the economic damages will have to be covered from the taxes paid by all citizens of Croatia”.

Zelena Akcija and Green Istria hope that the Court will consider their arguments and cancel the environmental permit allowing the construction of the Plomin C coal power plant.
