GNI UK Ltd acting as reasonable and prudent gas transporter are committed to operating a safe, reliable and
sustainability transmission and distribution network.
GNI UK own and operate the high pressure natural gas South West Scotland Onshore System (SWSOS) which
connects the upstream Great Britain (GB) National Transmission System (NTS) to the Republic of Ireland (RoI),
Northern Ireland (NI) and Isle of Man systems via subsea interconnector pipelines.
Brighouse Bay Compressor Station (BBCS) is a critical node located on the SWSOS consisting of six (6)
gas turbine compressor units which ensure safe and secure onward transportation of natural gas to the RoI
transmission system and Isle of Man offtake.
Brighouse Bay electrical demand is served by two (2) 11kV / 400V transformer substations, two (2) low voltage
(LV) electrical switchroom / motor control centres (MCC1 and MCC2) and one standby diesel generator.
MCC1 is in operation since the station was first commissioned in 1993. MCC1 electrical assets consist of one
(1) main distribution switchgear panel, three (3) motor control centres panels (MCC A, B, C), one (1) large
general services and lighting distribution panel and one (1) power factor correction panel. The main distribution
panel also incorporates transformer protection and standby generator controls.
MCC1 serves as the primary power distribution hub for the Brighouse admin and control building, utility
and services building, workshops, compressor halls and is critical for the reliable operation and continuous
availability of three (3) turbine compressor units (Units A, B, C).
GNI UK commissioned a site wide review of the Brighouse electrical installation in 2018. Findings from the
study show MCC1 electrical equipment has reached end of useful life with some functional units now obsolete.
The study also highlights constraints associated with operability and functionality of the current switchgear
arrangement, circuity configuration, means of isolation, and working area / operational access.
The study recommends to replace and upgrade all MCC1 equipment and install a new temporary transportable
generator inlet connection / changeover panel.
GNI UK now wish to procure the replacement of all associated MCC1 switchgear as detailed in the BBCS
switchgear specification (Ref. 18074-20-SP-0001)
The specification covers the design, manufacture, factory acceptance testing, storage, handling, delivery, site
re-assembly, verification testing and pre-commissioning of LV power switchgear and control gear.
Equipment to be supplied includes one (1) main distribution switchgear panel, three (3) motor control centre
panels (MCC), one (1) general service distribution board, one (1) power factor correction panel, and one (1)
transportable generator inlet / changeover panel.
