According to Official State Bulletin (BOE) From April 17, the company Renewables of Seville SL has proven its legal, technical and economic capacity to carry out an ambitious photovoltaic project in the province of Seville. This project, finally authorized by the Board of Directors on February 7, 2017, has received a favorable report from the Regulatory Oversight Chamber of the National Commission of Markets and Competition (CNMC).
The solar park will be built in the municipalities of Salteras and Guillena, in the province of Seville, with a potential of 110,4 MW of installed capacity. This type of photovoltaic installation plays a crucial role in the energy transition towards renewable sources in Spain.
Details of the 110 MW project in Guillena
The project includes the construction of an overhead power evacuation line, which will operate at 220 kV. This line will start from the transformer substation that will feed the photovoltaic park (220 / 20 kV). Its route will cover a distance of just over 10 km to the substation 220 kV Salteras, property of Spanish Electricity Network (REE). This infrastructure has been declared of public utility by the General Directorate of Energy Policy and Mines, which reinforces its strategic energy importance.
Ansasol's participation and the technical characteristics of the plant
The Spanish company Ansasol is responsible for developing the project. According to Ansasol's own website (ansasol.de), the company has a signed lease option contract for the land for a duration of 31 years, extendable for 12 more years.
The location in Guillena has been strategically selected due to its high annual horizontal irradiance (1.805 kWh/m²), which ensures high photovoltaic production. Ansasol estimates that the plant will generate around 177.000 MWh per year, equivalent to 1.603 kWh for each kW peak installed, making it a highly efficient installation.
La occupied surface The total area of ​​the solar modules will be 184 hectares, which represents less than two thirds of the total available area, which amounts to 282,71 hectares.
Renovables de Sevilla: Company promoting the project
Renovables de Sevilla is a limited liability company of Spanish origin, established on May 23, 2016. Its only shareholder, according to data from the CNMC, is Solarig Global Services S.A.., a company established in March 2016 with a total of 79 shareholders. Solarig is known for its many projects in the renewable energy sector, not only in Spain but also in other key European markets.
Financial opening: Lennox Partners as advisor
Lennox Partners, a renowned financial advisory firm based in London, has acted as advisor to Ansasol during the sale of the licenses for the Guillena project. Lennox Partners is a group specialized in clean energy that provides financial advisory, structuring and fundraising services. According to Miguel Poyatos, investment analyst at Lennox, this project is a clear example of how photovoltaics can be competitive without the need for government aid.
Technical details: Canadian Solar modules and efficiency
The preliminary project presented details that the solar park in Guillena will use photovoltaic modules of Canadian Solar CS6P, a polycrystalline model of 240 Wp with an efficiency of 14,61%This advanced technology will help maximize energy production in the park, ensuring optimal and efficient performance.
In addition to these modules, the option of using alternatives similar in terms of performance and efficiency is being considered, which guarantees flexibility and production security in the event of technological or market changes.
Photovoltaic energy: International perspective
At an international level, photovoltaic energy continues to gain ground over other energy technologies. Below we present some of the largest solar plants in the world today, which stand out both for their installed capacity and for their impact on the production of renewable energy.
Longyangxia Hydro-Solar PV Station (850 MW – China)
Located in the heart of China's Qinghai province, the plant combines hydroelectric and solar photovoltaic technologies to optimize year-round energy generation. It is divided into two construction phases and was executed by Powerchina.
Kamuthi photovoltaic plant (648 MW – India)
Located in the Tamil Nadu state of India, the Kamuthi plant is part of a broader initiative by the company Adani Green Energy. With a generation capacity of 648 MW, is the largest solar plant in India and the second largest in the world by installed capacity.
Star Solar Plant I and II (579 MW – California, United States)
Operated by Mid American Solar, a subsidiary of MidAmerican Renewables, this plant produces more than 579 MW and is located in the state of California. Built on approximately 13 square kilometers, it is capable of generating enough energy for more than 200.000 homes.
Topaz Solar Farm: 550 MW – United States
Topaz Solar Farm, also operated by MidAmerican Solar, was at one time the largest solar plant in the world. It is located in San Luis Obispo and occupies more than 26 square kilometers, with a production capacity of 550 MWThis plant has been a fundamental pillar in demonstrating the potential of solar energy in California.
The development of the 110 MW photovoltaic park in Guillena follows this clear example of modernisation and a decisive commitment to clean energy, with the aim of contributing to the mitigation of climate change and energy independence.
