Frequently Asked Questions - FAQ

When is a Medium Voltage Substation required?

The installation of a medium voltage (MV) substation is mandatory or economically beneficial in the following cases:

When the total installed power demand exceeds the low-voltage network limit (135 kVA).
When the facility requires continuous, stable power without interruptions (e.g., data centers, industrial plants, hotels, HVAC systems).
When the power load causes excessive voltage drops on the low-voltage network.
When there is a need for independent and reliable operation with local distribution.
In cases where the supply point is remote or where the infrastructure requires dedicated medium-voltage interconnection.

Our Approach

At Layer 1 Technologies, we treat MV substations as a critical part of any high-power infrastructure. Each project is fully engineered to meet energy, safety, and reliability standards — from design and procurement to testing and commissioning.

We deliver custom-built or containerized substations, ready for integration into data centers, industrial facilities, and other large-scale installations.

Indicative Applications

New data centers with medium-voltage connections and high energy availability requirements.
Industrial facilities with heavy equipment and local power distribution needs.
Commercial and logistics complexes requiring stable and efficient power supply.
Hotels and resorts with multiple HVAC systems and high simultaneous power demand.
Municipal buildings and public facilities requiring compliance with DEDDIE standards.
Prefabricated containerized substations for projects with space constraints or fast-track deployment.
