ONSHORE Wind Energy Small Wind Turbines OFFSHORE Wind Energy HYBRIDSystems

Offshore wind energy is a renewable energy sector that harnesses the power of ocean winds. Although Ukraine currently has no offshore wind farms, the country possesses significant technical and infrastructure capabilities both for implementing such projects and for developing domestic production of components for offshore wind farms, including the manufacturing of offshore foundations.

The first comprehensive assessment of offshore wind energy potential in the Black Sea and Azov Sea waters was conducted by the World Bank. According to its calculations, the theoretical available capacity of offshore wind in Ukraine reaches 251 GW. Meanwhile, the overall technical potential of the entire Black Sea region is estimated by World Bank experts at 453 GW.

Considering that this figure is theoretical, UWEA and the Technical University of Denmark (DTU) conducted additional calculations in 2023 and developed a preliminary feasibility study of Ukraine’s offshore wind energy potential.

Taking into account the existing wind resource, depth, and factors such as environmentally sensitive areas, shipping, fishing, etc., DTU experts concluded that the technically available potential for constructing wind farms with fixed wind turbines is 30 GW and with floating wind turbines – 20 GW.

Criteria and constraints for fixed and floating wind turbines


Ukraine is a participant in regional cooperation within the framework of the Common Maritime Agenda for the Black Sea. The Black Sea Strategic Research and Innovation Agenda includes stimulating and developing blue economy sectors, namely the development of offshore wind and wave technologies.

Considering the experience of EU member states and Energy Community countries that have access to the Black Sea and demonstrate high indicators of wind energy development and greenhouse gas emission reductions, launching the offshore wind energy market in Ukraine is one of the best methods for accelerating the energy transition and achieving the goals of the EU Green Deal.

White Paper “Offshore Wind Energy and Green Hydrogen: Opening New Frontiers of Ukraine’s Energy Capacity”

Small and medium-sized wind energy installations are used to meet the electricity needs of individual households, as well as small and medium-sized enterprises (SMEs).

The unit capacity of such installations can reach up to 20 kW for small systems and from 20 to 500 kW for medium-scale systems. To increase their efficiency and ensure uninterrupted electricity generation, small and medium wind turbines can be installed together with low-capacity solar systems, forming so-called hybrid systems.

Today, the geography of projects involving autonomous generation systems based on wind energy for household consumers and SMEs covers almost all regions of Ukraine.Small and medium wind turbines provide personal energy independence, additional income, and support the decarbonization of business activities (for SMEs).

Modern onshore wind energy in Ukraine began to develop in 1993 and gained significant momentum after the introduction of the “green” tariff in 2009. Onshore wind power plants operating in Ukraine consist of multi-megawatt wind turbines, with individual unit capacities ranging from 3 to 6 MW. As of December 2025, the total installed capacity of onshore wind energy in Ukraine is 2.3 GW. There are 40 wind power plants across Ukraine, and wind energy is the second-largest type of generation among all renewable energy sources (RES).

After russia’s full-scale invasion of Ukraine in 2022, 57% of wind generation remains on temporarily occupied territories. Nevertheless, the development of onshore wind energy in Ukraine has not stopped.

Since the beginning of 2022, 573 MW of new wind power capacity has been added to the Ukrainian energy system. Today, the geography of large onshore wind farm projects covers almost all regions of Ukraine, with a particular focus on the central and western regions. According to calculations by the U.S. National Renewable Energy Laboratory (NREL), conducted in partnership with the Ukrainian Wind Energy Association (UWEA), the average annual wind speed in Ukraine at a height of 120 meters is 7–8 m/s.

Renewable energy sources require system balancing, since electricity generation from “green” power plants depends on sunlight and wind speed. Before russia’s full-scale invasion of Ukraine in 2022 and the resulting changes in the structure of the Unified Energy System, balancing of renewable generation in Ukraine was provided mainly by thermal power plants. This situation was referred to as the “green-coal paradox.” At the same time, the consequences of the large-scale war have prioritised the development of decentralised and renewable energy sources, which has, in turn, increased the need to address the issue of their system balancing.

Nowadays, two main methods of balancing renewable energy generation are known worldwide, both of which are relevant for Ukraine’s development:

  1. through flexible (dispatchable) generation capacities
  2. through “green” hybrid power plants

Hybrid power plants are facilities that combine more than one type of electricity generation into a single integrated system.

According to research by the international engineering company AECOM, the combined or synchronous operation of multiple renewable energy sources can reduce capital expenditures by 3-13% and operating costs by 3-16%.

By integrating different types of generation such as solar power plants (SPP), wind power plants (WPP), and energy storage systems (ESS), hybrid power plants make it possible to compensate for fluctuations (“dips”) in the output of one generation source with another.

As a rule, energy storage systems are an essential component of such plants, as they increase overall reliability and, when needed, provide ancillary services to the power system, such as voltage regulation, balancing, and other stability functions.

Hybrid power plants are flexible in scale and can be built to supply electricity for small, medium, or large enterprises, as well as for regional or national power grids.

The development of the “green” hybrid power plant segment is strategically important for Ukraine’s energy system due to:

  • ensuring the predictability and stability of renewable energy generation;
  • increasing the flexibility and stability of the power system;
  • reducing imbalance volumes;
  • decreasing the number of system outages;
  • ensuring continuous power supply to electrolyzers in green hydrogen production;
  • improving project quality and economic efficiency.

UWEA closely cooperates with the relevant state authorities to create a legislative framework for the development of such a market segment as “green” hybrid power plants. In particular, it is necessary to: develop the appropriate regulatory and legal frameworks to define, in national legislation, different types of hybrid generating installations; standardize grid connection requirements, procedures for accounting of generated electricity, and the operation of hybrid power plants.
