In accordance with provisions of the amendment Act on maritime areas, construction of offshore wind farms in Poland is possible only in the exclusive economic zone, i.e. 12 nautical miles (approximately 22.22 km) offshore. The Poland’s exclusive economic zone encompasses an area of approximately 22.5 thousand km².

On the basis of:    
„Wind power development in Poland by 2020 – a vision”, a report developed by the Renewable Energy Institute for the Polish Wind Energy Association, Warsaw, November 2009

Theoretical potential: 130 GW.
However, this potential is impossible to exploit, for it assumes the use of the entire area of internal maritime waters and the territorial sea for wind power purposes.

Technical potential: 7.5 GW.
Current spatial constraints applicable to the location of offshore wind farms are much more strict than onshore. With regard to technical possibility to build wind turbines (water depth) and conflicts with the use of maritime areas it has to be stated that only an insignificant part of the area (up to 5%) could be used for wind farm construction in the 2020 perspective. Furthermore, environmental constraints related to the inclusion of large parts of Polish maritime waters in the NATURA 2000 network apply to offshore areas; however, the entire available area is characterised by advantageous wind conditions.
The Maritime Institute in Gdańsk, on the basis of analysis of natural determinants and potential spatial conflicts, designated on the area of the Polish territorial sea and the exclusive economic zone sites with technical potential of up to 20 GW. Exclusions related to NATURA 2000 sites reduce this potential to 7.5 GW.

Economic potential: 7.5 GW.
For offshore wind power it was assumed that the entire technical potential may be exploited to satisfactory economic results, hence it corresponds to 7.5 GW of capacity.

To build an offshore wind farm an investor must acquire a number of permits. This may last from 3 to as much as 7 years. The required decisions include:

1.   A permission to build and operate artificial islands, structures and facilities in Polish maritime areas – i.e. the so-called location decision, issued by the Minister for Infrastructure upon application of the investor for a site selected by him; after adoption of a local spatial development plan for maritime areas – by Director of the relevant Maritime Office;

2.   Decision on environmental determinants – issued by the Regional Environmental Protection Directorate;

3.   Grid connection conditions issued by the transmission system operator;

4.   Building permit – issued by the Province Governor.

The procedure for the acquisition of the location decision is laid down in the Act on maritime areas of the Republic of Poland and maritime administration dated 21 March 1991. An amendment thereto (Journal of Laws 2011.134.778) allowed for implementation of offshore investments in Polish maritime areas by adapting provisions regulating the issuance of permissions to build and operate artificial islands, structures and facilities to the determinants of the investment process in this sector of the economy. The amendment extends the validity period of the permission from 5 to 30 years, with an option to extend it by further 20 years.

The Act bans construction and operation of wind farms in internal maritime waters and the territorial sea.

Regardless of the location of an investment, an authority charges a fee for the issuance of the permission in the amount equivalent to 300 calculation units. If the investment is located within the exclusive economic zone, an additional fee in the amount of 1% of value of the planned project is charged. The investor shall pay the additional fee as follows:

1.   10% of the full amount of the fee within 90 days from the day when the decision became final;

2.   30% of the full amount of the fee within 30 days from the day, when the building permit for the project became final, or, when the building permit is not required, within 30 days from the day when the construction of the project has started;

3.   30% of the full amount of the fee within 30 days from the day, when operation of the investment has started;

4.   30% of the full amount after 3 years from the date of payment referred to in Item 3.
