The cost of the project is KZT 45 billion tenge, while the Development Bank of Kazakhstan (DBK, a subsidiary of Baiterek Holding) provided a credit line in the amount of KZT 30.5 billion. The financing schedule is 10.5 years; the remuneration fee is 12.58% per annum. "We have financed the first start-up complex so far. To date, the Bank has also approved the second stage of this project," said Aizhan Bitebayeva, senior banker of the DBK Directorate for Client Relations.
The representative of the Bank noted that energy, including renewable energy sources, is one of the priorities for the national development Institution.
According to Aizhan Bitebayeva: "The Bank's subsidiaries also participated in the financing of this project. The transforming substation of this project was financed under leasing from DBK-Leasing company, and equity financing from DBK Equity Fund was also attracted."
Yedil Saryev, Director of ЦАТЭК Green Energy told in more about the work of the wind farm.
"The source of raw materials for our plant is kinetic wind energy, the wind farm productivity directly depends on the strength and direction of it. In this regard, first of all, before the start of the project, we focused on finding a suitable site with energy efficient climatic conditions.
The preliminary selection of sites for the construction of the wind farm was carried out on the basis of a wind atlas prepared by UNDP, according to its data, potential land parcels with developed infrastructure, such as roads, networks, power lines, etc., were considered. After determining the main construction area of the WPP, for more detailed meteorological information, we installed our own meteorological mast with a height of almost 100 meters.
Having carried out a tremendous job, including measuring about 7 million speed readouts, its direction, air pressure and temperature, we made sure that the site is suitable for the installation of wind turbines," he said.
Then, according to him, began the most difficult part of the whole project - the delivery of components. The fact is that the height of one turbine from its base to the tip of the blade is 140 meters, which is comparable to the height of Khan Shatyr, the landmark of Nur-Sultan.
"The length of one blade is 55 m. Imagine how huge the components are. They were delivered from Denmark, Germany and Spain. The entire logistics route took us about 6 thousand km and, according to the manufacturer of turbines – Vestas company, our project was world’s top in terms of length and complexity of the delivery route", - said the company's chief executive.
Delivery was carried out by sea from Europe through Turkey and the Black sea, as well as through the Volga-to-Don Channel to Samara, where the overall details were loaded on special trucks and taken to Kazakhstan.
"The column with a length of more than one kilometer delivered turbine components through Aktobe, Kostanay, Nur-Sultan to the construction site. To do this, we had to modify many roads along the route, and this is a height increase of the power line above the roads, strengthening and construction of new roads on order to perform safe turns of haul trucks carrying out logistics of oversized turbine components, including indecomposable blades of more than 55 meters long. To install the stations, two huge cranes with a capacity of 750 tons and 400 tons were used," said Mr. Saryev.
According to him, now all generated electricity is supplied to the network of KEGOC JSC, the system operator. The consumer of the full amount of generated electric energy, in accordance with the legislation in the field of support for the harnessing renewable resources, is the Financial Center for Support of Renewable Energy Sources LLP.
Our station is capable of generating electricity at wind speeds ranging from 3 to 25 m/s," he explained.
At the same time, the wind farm is located on the territory of 119 hectares.
"After the commissioning of the first start-up complex, we organized fifteen job opportunities. When the wind-power station reaches its design capacity, we will increase the staff number to 19 people," said Mr. Saryev.
After the launch of the first stage of the project, the company began the construction of the second one.
"The second launch facility will also be located inside the allocated territory of 119 hectares, where it is planned to install 15 additional turbines. At the same time, their blades will be longer, the diameter of the rotor will be 117 m. The company plans to put into operation the second launch facility in the second half of 2020. As can be seen from the above, the total capacity of the wind farm will increase to 100 MW. This is enough to cover the electricity needs of three district centers or more than 10 thousand homes," said the director of the park.
In addition, the company plans to create an energy research center.
"We would like to attract the attention of not only experts but also to teach the oncoming generation to the careful attitude of nature, how to properly convert renewable energy sources and make the environment work for the benefit of mankind," concluded Y.Saryev.
