The Baltica 2 farm will cost 30 billion zlotys and it only has 1.5 GW. This brings us close to PLN 20 million per megawatt. These are only capital expenditures, to which you have to add financial costs and increasing operating costs. Even if we didn't take all the subsidies into account, energy from offshore wind is very expensive and we can already talk about more than PLN 1,000 per 1 MWh, and this is not the last word. In comparison, from conventional power plants, even if you pay ETS, we are talking about the amount of 450-500 PLN/MWh. What does the subsequent operation look like? How long will such windmills operate and deliver energy? These farms are also expensive to operate. It used to be assumed that it would be a bit like that with them, that one would put up this "windmill" and it would spin for 15 years. It turns out that it won't, because sea conditions are so harsh that these farms require repairs, such as blade replacement, after just a few years.The article discusses the growing role of offshore wind farms in Poland's energy transition. The construction of offshore wind farms aims to meet the demand for electricity, but is associated with high investment and operating costs. The planned development of the power grid and the construction of wind farms generate significant costs, which will have to be covered by the state.
