Substation Construction and Minipillars

Substation Construction

The following describes the standards to which you must comply if you are required to construct a substation building.

You are required to build a substation building if:

  • Your connection Maximum Import Capacity (MIC) is of 150 Kilovolt-Amperes (kVA) or more.
  • The Connection Agreement or Quotation Letter which you received from us specifies that you must provide a substation building.

Medium voltage substation building: general specification no.13320

A medium voltage (MV) substation building contains the equipment that connects a site to the electricity network.

Because this unit will subsequently form part of Ireland's electricity distribution system, it must be constructed in accordance with the specifications of ESB Networks. Ownership of substation buildings is transferred to ESB Networks following completion.

Construction Specifications

These documents set out the construction specifications to be followed for MV substations.
