At the workshop dedicated to the World Wind Day, Andrew Konechenkov delivered some interesting presentations: “Wind power in the CIS and Ukraine. Untapped potential and political risks” and “Stages of implementation of wind farm construction projects”, he also raised a number of topical issues of wind power development and answered the questions from the audience.
At the beginning of his presentation, the expert spoke about the benefits, achievements and trends in the wind energy sector.
The economic benefits of wind power:
• attracting investments and new technologies into the national economy;
• reduction of consumption of imported fossil fuels;
• creation of new jobs;
• stabilization of energy prices, the lack of price shocks;
• additional income for landowners.
▪ USA: 35% of electricity from wind power by 2050;
▪ EU wind power surpassed hydropower, reaching a 15.6% share in the total installed capacity and becoming the third largest source of power generation;
▪ France: the law on energy transition is to reduce the share of nuclear power in electricity production from 75% to 50% by 2025, increase the share of generation from RES to 40% by 2030;
▪ China: more than 30 GW of new wind power capacity was introduced in 2015.
The expert drew his attention to the fact that the old projections of the future installed capacities in wind energy (and in renewable energy in general) seem today somewhat too high.
This situation stems from the fact that forecasts for several thousand megawatts were based on the outdated technology, “The potential of this sector is not declining, but the latest technology makes it possible to achieve higher capacity utilization rate in comparison with the technology, for example, that was used ten years ago. Accordingly, a smaller volume of installed capacity will be able to produce more electricity. This can be explained by the example of wind power in Ukraine: we don’t have to seek 15 - 16 thousand megawatts, the modern approach to assessment of potential capacity requirements has reduced this figure to 5 - 7 thousand.”
The specialist pointed out the new developments in land-based wind turbines:
The US company GE.
3.4 MW turbines. The tower height of 85 - 155 m. Designed for the average annual wind speed of 6 to 8.5 m/s.
The Danish company Vestas.
3.4 - 3.45 MW turbines. Multivariable technology platform, five variants of the rotor, two configurations of the nacelle, multiple power mode options and 15 variants of towers of different heights up to 166 m.
The Spanish company Gamesa.
3.3 MW turbines. The maximum energy production at an average annual wind speed of 7.5 - 8.5 m/s. Blade length of 64.5 m from fiberglass with minimal noise characteristics.
The German company Enercon.
3.3 MW turbines. Estimated average annual wind speed of 7.5 m/s. Blade length of 66.7 m. Each blade comes in two parts in order to optimize production and logistics.
The head of UWEA also described the experience of Ukraine's wind power development.
To date, an impressive figure of 514 MW of installed wind capacity has been reached. Yet, the share of energy produced from wind in the total energy balance is less than 1%. However, the trends in the development and plans of the country are ambitious: according to the national action plan on renewable energy, the installed capacity of wind farms is planned to increase to 2280 MW by 2020. The overall share of renewables in energy production in Ukraine will reach 11%.
Revitalizing of the renewable energy sector in Ukraine occurred after the adoption (in June 2015) of the legislation that tied the “green tariff” to a stable currency and eliminated a lot of the pre-existing barriers, such as the requirement of “local content”, imbalance of tariffs for different types of renewable energy sources. New legislation in the field of renewable energy, in the opinion of both Ukrainian and international experts, adopted a very effective form that attracts investors.
Andrew Konechenkov says, “Of course, wind power, and any other single source of energy, will not be enough to satisfy 100% of electricity needs. There should be reasonable and balanced approach. It is necessary to use wind energy where there is adequate capacity available for it – sites with average wind speeds in excess of 5.5 m/s. It is also necessary to support the development of renewable energy at the legislative level. It should be noted that Belarus has all the prerequisites for the development of wind power.”
In addition, the head of UWEA presented the “Stages of implementation of wind farm construction projects”:
1. Preparatory work.
2. Wind measurements for EIA.
3. Registration of land use right.
4. The calculation of Urban Planning.
5. Project work on the connection to the electricity grid.
6. Project documentation.
7. Wind farm construction.
8. Production and sale of electricity.
The expert revealed the details of each of the components represented by the steps and explained that the scheme had been tried out in Ukraine and can be applied in the Belarusian conditions.
The head of the project “Removing Barriers to Wind Power Development in Belarus”, Marina Belous, thanked the expert for the presentation and said, “Considerable experience in Ukraine can help Belarus avoid some of the complexities in the wind power sector.”
Andrew Konechenkov expressed his willingness to support the project “Removing Barriers to Wind Power Development in Belarus” as “Ukraine has already passed this stage, where Belarusian wind power is today, and is ready to share its experience.”
