Saguntum 400 kV Substation Authorized: What It Means for Parc Sagunt Industries

Key data

Industrial companies in Parc Sagunt have had, since September 26, 2026, a formal guarantee of reinforced electricity supply. The Resolution of September 3, 2026 from the General Directorate of Energy Policy and Mines grants Red Eléctrica de España, SAU both the prior administrative authorization and the administrative construction authorization for the new Saguntum 400 kV substation, with five new positions, located in the municipality of Sagunto (Valencia).

This decision is not a minor formality: it is the step that unlocks the effective construction of critical infrastructure for one of the industrial parks with the greatest growth potential in the Valencian Community.

What does this regulation establish?

The resolution grants Red Eléctrica de España two simultaneous and complementary authorizations:

• Prior administrative authorization: recognizes the viability of the project and its fit within the national electricity transmission network planning.
• Administrative construction authorization: enables the effective start of substation construction works.

The substation will have five new positions at 400 kV, a voltage level characteristic of the high-capacity transmission network. Its stated objective is twofold: to strengthen the security and reliability of the electricity transmission network in the area and to guarantee supply to the industrial plants of Parc Sagunt.

The project processing included an environmental impact assessment, whose Environmental Impact Statement (EIS) was approved in May 2026. The EIS incorporates relevant environmental conditions that Red Eléctrica must comply with during construction:

• Surveys of protected flora in the affected area.
• Compensatory forestry work in the Muntanyeta de les Lloses.

Additionally, the resolution contemplated the coordination of the diversion of a section of Enagás pipeline affected by the works, which implies technical coordination between critical infrastructure operators.

Economic and operational impact

For industrial companies in Parc Sagunt, this authorization has direct consequences for their strategic and operational planning:

• Greater electrical connection capacity: the five new 400 kV positions significantly expand the available capacity to connect new plants or expand existing ones, eliminating one of the main bottlenecks for industrial implementation.
• Reduced supply risk: a dedicated substation strengthens local network reliability, reducing exposure to interruptions that could halt high-energy-intensive production processes.
• Investment attraction: the guarantee of robust electrical infrastructure is a determining factor for large industrial investors—especially in sectors such as automotive, logistics, or advanced manufacturing—to confirm their establishment in the park.
• Coordination with Enagás: the diversion of the affected pipeline means that companies depending on that section must be aware of execution timelines to avoid interruption of their gas supply during construction.

Who does it affect?

• Red Eléctrica de España, SAU: holder of the authorizations and responsible for the construction and operation of the substation, as well as for compliance with the environmental conditions of the EIS.
• Industrial companies installed in Parc Sagunt: benefit directly from improvements in electrical supply capacity and reliability.
• Developers and investors with projects in Parc Sagunt: the authorization removes a key uncertainty for confirming investments requiring high electrical demand.
• Enagás: affected by the diversion of the pipeline section, with operational implications during the construction phase.
• Municipality of Sagunto (Valencia): territorial impact both from the works and from the industrial development that the infrastructure facilitates.

Practical example

A large energy-consuming manufacturing company evaluating the installation of a plant in Parc Sagunt needs, as a prerequisite for investment, to confirm that it will have sufficient and reliable electrical connection to the transmission network.

Before this authorization, connection capacity in the area was limited by existing infrastructure. With the Saguntum 400 kV substation authorized and its five new positions, that company can now negotiate with Red Eléctrica de España its connection point to the transmission network on a solid technical basis, knowing that the infrastructure will be available. This could be the factor that unlocks the signing of the investment contract and associated job creation in Sagunto.

Similarly, a company already installed in the park that depends on the section of Enagás pipeline affected by the works will need to coordinate with Enagás the timeline for the diversion to anticipate possible temporary interruptions in its gas supply and activate contingency plans if its production process requires it.

What should companies do now?

1. Companies with implementation projects in Parc Sagunt: contact Red Eléctrica de España to initiate or advance the procedures for requesting access point and connection to the transmission network, taking advantage of the new capacity enabled by the Saguntum substation.
2. Companies already installed that depend on the Enagás pipeline affected: request information from Enagás about the timeline for diverting the affected section and evaluate whether it is necessary to activate contingency supply plans during construction.
3. Developers and investors in Parc Sagunt: update the energy feasibility studies of their projects by incorporating the new capacity of the Saguntum substation as available infrastructure.
4. Companies with environmental sensitivity in the area: review the conditions of the EIS (approved in May 2026), especially those relating to protected flora and forestry work in the Muntanyeta de les Lloses, to anticipate possible impacts on their activities during the construction phase.
5. All affected parties: follow the publication of construction execution timelines by Red Eléctrica de España to plan in advance any operational impact.
