Gran Canaria in energy is not the disaster of Tenerife, where before the pandemic they were able to bring 5,1 million tourists to the island who, added to 1 million supposed inhabitants (in 2014 José Miguel Bravo de Laguna warned that they were inflating the census to capture more EU aid than Gran Canaria) without the capacity to even put a microwave in an aparthotel.
In Gran Canaria, the island's council has permanent coordination of network implementation with Red Eléctrica de España despite Endesa's alleged permanent boycott of the island's development so as not to lose its monopoly on generation. The network plans on the island are long-term programs and thanks to the excellent technical coordination agenda between the Government of the Canary Islands and local administrations, the south of Gran Canaria can reset its energy system without fear of a 'zero' of several days, such as It happens in Tenerife.
The new plans for energy generation in the south of Gran Canaria involve reinforcing the current north-south axis between Barranco de Tirajana and Sabinal. To this end, before 2026 the repowering of the El Escobar-Cinsa-Marzagán 66 kV, El Escobar-Telde 66 kV and Matorral-Lomo Maspalomas 66 kV lines and installation of DLR equipment in Aldea Blanca-Agüimes-El Escobar 66 will be carried out. kV.
Likewise, the input-output in Aldea Blanca 66 kV of the 6 kV Barranco de Tirajana-El Escobar 6 line will be improved, which is added to the new Barranco de Tirajana III 220 kV substation, with connection through a single-circuit line-cable to Sabinal 220 kV and through double circuit cable with Barranco de Tirajana II of 220kV.
This is done to allow the adequate integration of the connected renewable energy in the north-south axis (both already installed and future, including possible offshore wind generation), strengthen the connection between the north and south areas of the island of Great Canary Islands, necessary to guarantee the security and quality of supply in a scenario with a high concentration of generation on the island in the southeastern area.
For the entire 66 kV north-south axis, the capacity to increase its use has been evaluated through dynamic capacity monitoring (DLR), through repowering
and by installing flow control systems. However, these measures are insufficient, so reinforcement of the 220 kV shaft is also proposed. As an alternative to the latter, the possible closure of the mesh in the western area (Mogán-La Aldea-Agaete 66 kV) has been analyzed, a solution ruled out due to its high risk of implementation and less effectiveness for security of supply.
