ardiff Pumping Station needed to upgrade its power supply and replace its four existing 46-year-old Blackstone generators that support their water flow pumps. The existing generators were no longer fit for purpose, as they could not support load sharing and didn’t synchronise. Cardiff Pumping Station is a combined station that passes through 500 – 1200 litres of water per second on a dry day, known as ‘normal dry weather flows’. However, in storm conditions, this could increase by 3-6 times.
Shenton Group was one of three generator suppliers approached by ARUP on behalf of Welsh Water to assist with the initial designs and feasibility. Along with offering a turnkey project where we would also remove the old equipment, the design the Shenton Group put forward negated the need for rental generators and reduced the amount of cable, which would save the client £250,000. This ultimately lead Shenton to win the project, says the company. Altogether, the Shenton Group has provided three 1.25 MVA prime rated generators in N+1 configuration in 75 @ 1m acoustic enclosure.
