South Quay Plaza Redevelopment

Project overview

Eclipse Power Networks have been appointed as the Independent Distribution Network Operator (IDNO) for the adoption of Berkeley’s Foster + Partners designed South Quay Plaza Valiant Tower in London’s Canary Wharf area.

The slender 68 storey glass and steel tower will be one of the tallest residential buildings in Europe. It includes 665 registered MPANs and incorporates an IDNO network extended throughout the building.

The 11kV connected development has its own IDNO substation in the building basement and LV distribution network within the building.

The challenges

Eclipse Power Networks worked closely with the ICP, H&MV to develop an effective adoptable design. This met the building and client requirements in a very prestigious Berkeley Group development.

The adopted network extends from the UKPN 11kV Point of Connection (PoC) via an IDNO substation and up cable risers to grouped meter positions within riser cupboards within every other floor. As such, the design needed to consider IDNO access as well as fault restoration options.


H&MV were happy to have support from Eclipse Power Networks on such a significant residential development project.

Adopting a collaborative approach, combining our collective experience and expertise, ensured the project was delivered on time, within budget and with the highest standards of quality and safety.
