⚡Pavagada solar park, also known as Shakti Sthala, is a 2000MW solar complex developed in Pavagada, Tumkur district, approximately 180km from Bengaluru, Karnataka, India. The developers increased the capacity by 50MW.
⚡The project was developed by Karnataka Solar Power Development Corporation Limited (KSPDCL), a joint venture between Solar Energy Corporation of India (SECI) and Karnataka Renewable Energy Development Limited (KREDL), with an estimated investment of Rs16.5bn ($2.5bn).
⚡With the commissioning of the last 100MW of the solar project by SB Energy in December 2019, the world’s biggest solar park became fully operational.
⚡Development is part of the Ministry of New and Renewable Energy (MNRE) scheme, which aims to build solar parks and ultra-mega solar power projects to achieve the 100GW solar power target by 2020.
⚡The project is part of Karnataka’s Solar Policy 2014-2021, which aims to shift the dependency from conventional power resources to eco-friendly energy resources.
⚡Pavagada solar park construction started in October 2016 and the 600MW first phase was commissioned in January 2018.
⚡The project will offset approximately 578,631t of carbon dioxide emissions a year.
🔎🌞PAVAGADA SOLAR PARK LAND AREA DETAILS
⚡Pavagada solar park spans a total area of 13,000 acres (53km²) across the villages of Nagalmadike Hobli, including Vallur, Balasamudra, Tirumani, Rayacharlu and Kyataganacharlu in Pavagada.
⚡KSPDL entered a 25-year lease agreement with landowners to obtain more than 11,000 acres of land on an annual lease rental basis for the project development.
⚡The solar park is divided into eight sections with a capacity of 250MW each. The eight sections are further divided into five blocks of 50MW each. A number of companies, including Azure Power (100MW), SB Energy (200MW), Fortum (250MW) and Tata Power Renewable Energy (250MW), are involved in the development.
⚡In April 2019, ReNew Power commissioned its 300MW solar plant at the project and Avaada Power operationalised a 150MW solar project in the park.
🔎🌞Details of the solar panels installed at Pavagada solar park(as which type of solar panels has been used) 🌞
⚡Fixed-tilted photo-voltaic solar panels with a tilt angle of 15° due south and flat panels are installed at the solar park. A total of 166,668 units of Canadian Solar’s CS6X-300P solar panels and 499,995 units of First Solar’s FS-3100 solar photovoltaic modules were used for each 50MW block.
⚡The CS6X-300P models have 72 poly-crystalline cells measuring 156mm x 156mm. The module efficiency is up to 15.63% with an optimum operating voltage of 36.1V. The module frame material is of anodised aluminium alloy and the front cover is of 3.2mm tempered glass.
⚡The FS-3100 models feature advanced thin-film technology and are equipped with a cadmium sulphide/cadmium telluride (CdS/CdTe) semiconductor and 146 active cells. The nominal power and voltage are 100W and 46.8V respectively.
⚡The panel has 3.2mm heat-strengthened front glass laminated to 3.2mm tempered back glass cover with Series 3 black laminate material with edge-seal encapsulation.
⚡Canadian SOLARS CS6X-300P generally has a price of some $290.11 and the company gives a warranty of 25 years. The total voltage of the panel will be 36.1 volts. The frame of the panel is made up of Anodized Aluminum Alloy. The connector of the panel is compatible with MC4 or MC4 Comparable. the important points for using Canadian SOLARS CS6X-300P panels is because :
- High module efficiency up to 15.90%
- Positive power tolerance: 0 - +5W
- Robust frame to up to 5400 Pa load
- Self-cleaning surface
- Outstanding performance at low irradiance
- High energy yield at Low NOCT(nominal operating cell temperature).
🔎🌞Other infrastructure details of pavagada solar park🌞
⚡Auxiliary infrastructure at the solar park includes a water abstraction system such as bore-wells, waste management systems, roads and warehouse and storage facilities.
⚡Other infrastructure include an administration and operations building, temporary residential facilities, power lines, construction labour camps, and sub-station / switching station.
🔎🌞After generation of electricity, how the electricity is transmitted from grid is explained below
⚡Each 50MW block of solar park transmits power to either a 220kV / 66kV or 220kV / 33kV pooling substation via 66kV / 33kV double-circuit underground cables. The pooling station is connected to a proposed substation operated by Power Grid Corporation of India Limited (PGCIL).
⚡Power voltage is stepped up to 400kV / 220kV at the PGCIL substation, which is connected to the 765kV / 400kV PGCIL station situated at Vasanthanarasapura in Tumkur and the 400kV / 220kV substation located at Gooty in Andhra Pradesh.
⚡The grid connection of Pavagada solar park was completed by June 2019.
🔎🌞List of Contractors involved in the construction of pavagada solar park🌞
⚡L&T built four 2 x 150MVA, 220/66kV substations, while Amararaja Power Systems built four 4 x 80MVA, 220/33kV substations.
⚡Viji Power Transformers constructed a 2x8MVA, 66/11kV substation.
⚡A total of 75km of the road was constructed by KMC Constructions, while Kumar Electricals installed the street lights along the roads and auxiliary supply to the 220kV substations.
⚡Bhagya Electricals and Manasa Enterprises have received contracts for the development of power lines and power supply arrangement for the substations.
⚡the government had some other plans in pavagada like they initially thought of developing wind Mills in pavagada and later changed their plans to establish solar park in pavagada.
⚡In March 2017, Karnataka Energy Minister DK Shivakumar told the BANGALORE MIRROR that the government was looking to generate wind energy by setting up windmills in Pavagada. Preliminary estimates from the KREDL indicate a potential wind power generation of 250-300 MW.
