83MW Solar Photovoltaic Power Plants

Kazakhstan has been actively working to develop and expand its renewable energy sector. The country possesses significant potential for renewable energy sources, particularly wind and solar power, due to its vast land area and favourable climatic conditions. Covering an area of 2.724 million square kilometers, the country has the ninth largest territory in the world. Kazakhstan has now established around 130 renewable energy facilities, and the country’s potential for green energy generation is huge. Kazakhstan has set an ambitious goal – to reach carbon neutrality by 2060. As the largest Central Asian country, Kazakhstan, has a great potential of solar energy. Solar power has a great potential as a renewable energy resource due to sparsely populated large areas and the climatic conditions, especially in southern Kazakhstan with an annual sunshine of 2200 to 3000 hours. During the summer months (June – August), due to its geographical location, the southern part of Kazakhstan receives direct solar radiation for the most of the daylight hours which constitute 83 – 96% of the maximum possible value. According to plans by the Ministry of Energy of Kazakhstan, in the region RES projects with a total capacity of 2,615 MW will be implemented until 2025 . In 2021, the total installed capacity of RES in Kazakhstan amounted to 2,010 MW, of which 49 were solar power plants. Overview The project aims to construct, operate and maintain a 83 MW photovoltaic power generation plant in Turkestan Region, in the South of Kazakhstan. The power plant will use poly-crystalline photovoltaic modules and occupy a 83.20-hectare site. It will be connected to the KEGOC grid by underground transmission lines linked to an existing MV/HV transformer situated nearby from the site. The project involves the construction of a cable duct to connect the plant to the electricity transformation station for delivery to the National Energy Transmission Network. Along its entire length, the cable duct will be completely underground. The connection of the plant will take place via a 220kV antenna on the new 220kV transformation station which will be interconnected to the NTG (National Transmission Grid) by means of an aerial connection to the electrical substation, located approximately 1.5 km away. Keypoints Status: Pending – Ready to Build (Diagram Distribution Power under review) Denomination: Turkestan I, Kazakhstan Number of Panels: 132,000 Power MWp: 83,160 Area: 130 Ha approx Number of Strings: 6,000 Number of panels: 132,000 Rated installed power: 83,20MW Number of inverters: W 24 Inverters typology: SMA Sunny Central 2.060-EV DC to AC ratio: 1500V 1.13 Technical Data The Connection User system (IUC) will consist of: − A 30/220 kV electrical transformation station which conveys the energy produced by the plant through 30 kV connections and carries out the transformation at the nominal voltage of 220 kV with 2 transformer uprights equipped with TR 30/220 kV of 45 MVA ; − A delivery stall at the exit of the 220kV line, for the interconnection in AAT cable towards the electrical station of the NTG, of the transformation station of the planned plant; − AAT connection in overhead (or, if necessary, underground) cable duct at 220 kV between the new transformer station and the NTG (section of connection  – SE in the project). Electromechanical Connection The station will be built in a “single busbar” configuration (three conductors) at 220 kV, with air insulation. The 220kV busbar system will be characterized as shown below.
