Renewable Energy

Generally, the Developer will construct the renewable energy assets, whether it be a solar farm or a wind turbine.

IUS are ideally paced to provide the private wire substations and cable works as well as the contestable connection to the grid network.

IUS support the UK sustainable energy agenda and have a particular strength in Wind, Solar and Battery Storage projects.

IUS has extensive experience in the installation of renewable energy systems, including operating as an Independent Connections Provider, offering a full turnkey solution.

Decarbonisation is at the forefront of Government policy and IUS are here to assist you with the goals and targets of your business. IUS have been involved in contestable connections and private infrastructure to harness power from wind, solar, wave, anaerobic and heat exchange systems.

We can assist clients in gaining the maximum benefit from their infrastructure to contribute to the Global Challenge.

 

As the demand for renewable energy has grown, so too has the number of projects IUS has delivered.

This is linked to the full turnkey services IUS provide, which the site Developer benefits from. Our aim is to provide cost saving solutions without any reduction in quality. The portfolio of projects completed is testimony to our success.

Project

33kV Substation Installation

Location

Caithness, Scotland

SERVICES PROVIDED
  • 33kV Contestable connection work
  • On-site private 33kV infrastructure work
  • Procurement of equipment
  • Supply and installation of substation GRP to DNO standards
  • Installation of 33kV switchgear
  • Heavy lifting operations
  • Protection design
  • Interfacing with DNO network and generation control systems
  • Testing and commissioning
  • Preparation of hand back documentation
  • Principal contractor for the connection works
OVERVIEW

IUS completed the electrical construction works associated with the Lochend Wind Farm development. The connection of four 2.3MW Wind Turbines to the grid required a 33kV extension to the Scottish and Southern Energy electrical network. IUS was appointed to undertake the design and installation of the 33kV contestable elements of the connection activity.

DESCRIPTION

The project involved the supply and installation of a specialised multi-part GRP enclosure, which reduced construction costs and on-site installation times. Within the GRP housing, 33kV Schneider Electric WS switchgear was installed with connections made to the extra high voltage cable circuits using Pfisterer terminations. The design, installation, and commissioning of all associated DC and control systems also formed part of the IUS work scope.

Client

Lochend Windfarm

Project

33kV Cable Ploughing

Location

Caithness, Scotland

SERVICES PROVIDED
  • Ploughing of two 33kV cable circuits
  • Installation of fiber optic cable for entire route
  • 33kV cable jointing and testing
  • Duct installations for road crossings
  • Procurement of equipment
  • Provision of specialised vehicles for site access
  • Provision of full GPS tagged as laid records
OVERVIEW

IUS completed the installation of two 33kV cable circuits, which form part of the Lochend windfarm connection works. This was a challenging route and IUS implemented cable ploughing technology.

DESCRIPTION

The contestable connection design required the installation of 18km of 33kV cabling across two feeders between the existing Distribution NetworkOperator (DNO) point of connection and the new windfarm. The route was across soft peat and through mature forestry. Due to environmental restrictions the works were completed in December and January, which presented additional challenges.

The use of cable ploughing techniques and low ground pressure bearing equipment significantly reduced the installation timescales and disruption to the ground conditions. A Hagglund ATV was deployed to ensure safeaccess and egress to the sites at all times.

SERVICES PROVIDED
  • Outline and detailed design(Electrical and civil)
  • 33kV Contestable connection work
  • On site private 33kV infrastructure work
  • Procurement of equipment
  • Construction of primary substation building to DNO standards
  • HDD railway crossing
  • Possession planning
  • Installation of 33kV switchgear
  • Installation of containerised substations on raised platforms
OVERVIEW

IUS have completed the electrical construction works associated with the Melton Wind Farm development. The connection of the two 2.3MW Wind Turbines to the grid required a 33kV extension to the Northern Powergrid (NPg) electrical network. IUS were appointed to undertake the design and installation of the 33kV contestable elements of the connection works, along with the private 33kV and LV infrastructure.

DESCRIPTION

The project involved the construction of a combined building to house the 33kV NPg intake substation equipment and the customer owned 33kV switchgear.

The 33kV cable route to the new substation required the crossing of the Hull–London Railway Line by Horizontal Directional Drilling (HDD) methods. The IUS scope of works included all negotiations with Network Rail, HDD design and settlement calculations, possession planning and drilling operations.

The private electrical infrastructure installed by IUS included; 33kV, pilot and LV single core cables; a three panel 33kV switchboard; protection equipment; substation ancillary apparatus and two 2.5MVA containerised substations on raised platforms (flood risk mitigation).
