Generating electricity from wind power

Wind is set to become the main source of electricity in Europe by 2030, and Petrol is contributing to this by designing, building and operating wind farms.

Wind, a renewable energy source

Wind farms generate electricity using the kinetic energy of the wind. The latter is converted into electricity by wind turbines or wind energy conversion systems. The amount of energy produced from wind depends on the size of the turbine and the length of the wind turbine blades, as well as the wind speed.

Wind farm technology is evolving rapidly, while the costs are decreasing. New wind turbine technologies make it possible to harness wind competitively even at lower wind speeds (taller towers, longer wings and new aerodynamics), while at the same time making wind turbines taller, quieter and more friendly to small birds. As a result, wind farms are becoming increasingly competitive and desirable compared to conventional energy sources.

This is why Petrol is planning, building and managing wind farms in locations where it is possible to exploit the wind potential in an economically efficient and environmentally friendly way.

Why wind farms?

A competitive and fast-growing source of energy

Investment in wind farms is booming in Europe, with an average annual growth rate of 30% over the last five years. 

In addition to the falling costs of wind farms, wind-generated electricity has a low environmental impact. Additional benefits include the creation of new jobs and the price of electricity is lower or more competitive than other sources, with positive effects on the economy.

Geographical location of wind farms

Wind farms make the most sense for areas with constant winds above 5 m/s. The potential of wind is not negligible in the geographical area of our region, especially in Croatia, which has a very clear renewable energy strategy and a relevant legislative framework. Thanks to advanced technology, turbines with larger rotor diameters (>140 m) can be used in areas where we have slightly lower average wind speeds.

Wind farm planning

Before a wind farm project can be implemented, sophisticated environmental impact studies and bird monitoring, average wind speed measurements and wind characteristics analysis must be carried out. The complexity of the terrain and the availability of other infrastructure, which must be able to transport the equipment and connect it to the electricity grid, are also key factors in the design of a wind farm.

The design is followed by the construction of the foundations, transport of components, assembly and commissioning of the wind farm.

Business models

We develop and implement wind energy solutions primarily as an investor and partner in project development, where cooperation with local businesses and the environment is key. The Ljubač Wind Park is the first Petrol wind energy project to be implemented without financial support or subsidies. 

For larger projects, we also use the Upstream Power Purchase Agreement (PPA) model, which is a power purchase agreement that ensures long-term security of electricity supply and predictable costs.

Wind power for low-carbon mobility

The electric vehicles you charge at Petrol’s e-charging network are charged with electricity from a renewable energy source – wind. For this purpose, Petrol has leased the relevant certificates of origin for energy from wind farms, including our own wind farms in Ljubač and Glunča.

With renewables towards energy self-sufficiency

Energy self-sufficiency can also be achieved through a combination of different sources of electricity generation, preferably from renewable sources (wind, solar, hydro). Energy storage will play a key role in the future. 

At Petrol, we help towns and villages that want to ensure the reliability and security of their energy supply by designing, building and operating small and large-scale solar power plants for self-supply, and we can also integrate smaller wind turbines, batteries and charging infrastructure into a single management system, as we have done effectively in the village of Luče.

Petrol wind farms

Glunča Wind Farm

The Glunča Wind Farm is built near Šibenik in Croatia. It consists of nine turbines, each with a rated capacity of 2.3 MW. Each blade is 53 metres long, with an overall rotor diameter of 108 metres. The entire plant has a total rated capacity of 20.7 MW and an annual electricity production of 45–50 GWh, enough to meet the needs of around 15,000 average households.

Ljubač Wind Farm

The Ljubač Wind Farm is built near Knin in Croatia. The wind farm consists of nine wind turbines with a roto diameter of 131 meters. Each turbine has a rated power of 3.6 MW, giving a total capacity of just over 32 MW. The expected annual energy production of the wind farm is 96 GWh, which is sufficient for 30,000 average household consumers.
