UK Power Networks takes a shine to PASS M0

UK Power Networks has selected ABB’s innovative PASS M0 high-voltage switchgear to connect new solar farms to its 132 kV transmission network in the East of England.
The switchgear will act as the main grid connection points for new solar photovoltaic (PV) farms, with one of the first installations being for the Leicester Square PV farm on the Hempton Grid in Norfolk. To help spread the demand on its 11 kV and 33 kV networks, UK Power Networks is now offering 132 kV connections for major new solar farms, typically producing in excess of 50 MW.

Compact and fast-track
Following a stringent review process, UK Power Networks adopted ABB’s PASS M0 as the optimum switchgear for these projects due to its unique hybrid design that uses traditional air-insulated busbars to connect with other equipment in the substation, while the main bay functions are enclosed in a GIS housing to create an extremely compact installation footprint..
The PASS M0 modules will not only save space on site but will also enable a fast-track solution, as they are supply as completely pre-fabricated, pre-wired and pre-tested units. This reduces the need for civil works.
Metering and control in one
Because the PASS M0 integrates high quality tariff-code current transformers (CTs) and voltage transformers (VTs), UK Power Networks will be able to use it as a metering breaker to measure the quantity of power fed into its grid.
PASS M0 has full Energy Networks Association (ENA) approval and is rated up to 170 kV. It integrates all the necessary substation switchgear bay functions, including a circuit breaker, one or more combined disconnector / earthing switches, bushings for connection to single or double busbar systems and a current transformer (CT) in one compact module.
Another advantage is the PASS M0’s flexibility of configuration. It can be connected with various combinations of busbar and cable connections to suit different site needs.
PASS M0 modules will be installed at a number of sites in the eastern region of UK Power Networks’ operating area, which includes parts of Essex, Suffolk, Norfolk, Cambridgeshire, Bedfordshire and Hertfordshire. For some projects, they will be supplied directly by ABB to UK Power Networks, while for others, they will be purchased by the ICPs that are creating grid connections on behalf of solar farm developers.
