In Scotland IUS has delivered a Battery Energy Storage System (BESS), which impressed Michał Kuciński of Tesla. "I want to acknowledge the outstanding work that the IUS team has been consistently delivering at the Little Raith site over the past few months. Certainly, from my side, it feels like Tesla and IUS developed a partnership with a common goal of completing our BESS project on time, in the best possible quality. The team that I’m working with on day-to-day basis is of utmost help, impresses with professionalism, puts attention to small but important details and represents a united front with Tesla. I would like to express my sincere gratitude to the entire IUS team involved.”

OVERVIEW
Integrated Utility Services (IUS) carried out works at a large food manufacturing facility that provides products for supermarkets throughout the UK. Their intake substation is operated via National Grid Electricity Distribution (NGED). The HV configuration included an aged, oil filled (Brush) combined 11kV Switchboard, with 3 NGED owned panels and 3 customer owned panels.
There was also a separate, customer owned two panel Schnieder Electric CE2/CE6 switchboard, connected via a HV cable loop. Their power supply is essential and the benefit of having an Operation & Maintenance Agreement with IUS, for their private 11kV network, was demonstrated following a fault.
We have had historic problems with the old Brush switchgear with various fault repairs completed on this network. However, it was a flashover on the NGED owned 11kV metering Circuit Breaker, which caused a loss of supply and an emergency response from both IUS and NGED.
DESCRIPTION
The IUS Senior Authorised Person was called out to a loss of supply at the facility, attended the site and assisted NGED following a Distribution Network Operator Circuit Breaker trip.
To initially restore supplies, generation was arranged by the customer with IUS implementing the required safe system of work including HV switching and the issue of safety documents. This arrangement would provide a temporary supply solution and enable NGED to carry out any required repair works on their own equipment.
Following consultation with the client, it was decided the most appropriate way to proceed would be to replace the Brush oil filled switchgear with new Schneider Electric SF6 insulated apparatus. This would be achieved by extending the existing Schneider Electric switchboard with a further 3 panels. With safety documentation in place, the old Brush switchgear was disconnected and removed.
The new Schneider Electric apparatus was installed and 11kV cable jointing and terminations where undertaken. Working collaboratively with the customer and NGED the installation was completed, tested, commissioned and energised. This would allow normal supplies to be restored, and the generators to be disconnected.
