The transformation of Spain’s energy system is driving the modernization of electrical infrastructure across the country. The electrification of the economy, industrial development, the expansion of electric mobility, the growth of data centers, and the integration of new renewable energy sources are increasing the demand for greater capacity and flexibility across the transmission network.
Against this backdrop, and as part of the expansion and modernization plan for the national power infrastructure, the number of substations in Spain has grown significantly to ensure a safe, reliable, and resilient electricity supply capable of meeting both current and future energy needs. The commissioning of these substations will enhance system reliability, optimize grid operations, reduce operational risks, and lower greenhouse gas emissions by enabling greater integration of clean, sustainable energy generation.
To support this transformation, Spain continues to make significant progress in the integration of renewable energy, strengthening its position as one of the leading countries in the transition toward a more sustainable, competitive, and secure energy model.
To contribute to this development, CT participates in every stage of substation projects, providing engineering services, developing control systems, and completing the commissioning process. In addition, our specialists carry out functional and protection testing while integrating control and communication systems into the main operational systems to ensure reliable performance before the substations are brought into service.
Our team brings more than 15 years of experience, having successfully delivered projects at well over one hundred substations. Our commitment and proven track record have led us to participate, in 2025 alone, in the commissioning of the following substations connected to Spain’s transmission grid:
- Campofrío 220 kV Collector Substation
- Gerena PV Plant 220/30 kV
- Tabernas STATCOM
- Lirios PV Plant 220/30 kV
- Chucena 220 kV Collector Substation
- Campos del Río 400/132 kV Collector Substation
- Almodóvar del Río 220 kV Collector Substation
- Almodóvar Renovables PV Plant 220/30 kV
- Almodóvar & Guadalcázar PV Plants 220/30 kV
- Múdejar Norte 220/30 kV Collector Substation
- La Solana 220 kV Collector Substation
- Torreluenga Collector Substation 220/30 kV (Naturgy)
Backed by extensive expertise in electrical engineering, automation, and the commissioning of high-voltage infrastructure, CT Engineering Group remains committed to strengthening its role as a key technology partner in strategic projects supporting the modernization of the power grid, with the goal of advancing a more sustainable, digital, and efficient energy model across Spain.
