The Situation
The operator of a British, coal-fired power station, was aiming to reduce the running costs of their pump system, as part of a wider cost-saving initiative. The team within the specialist industrial pumps department at HAYLEY DEXIS got the call for assistance. They swiftly arranged a suitable date for a formal Energy Check to be carried-out in collaboration with Grundfos. This survey would focus on three ageing Weir pumps being used at the site.
The Solution
The Energy Check was completed onsite in accordance with the ISO 14414 Pump System Energy Assessment Standard, and revealed the potential for considerable savings to be made, both in terms of cost and in a reduction in carbon emissions. The recommended switch of the current pumps for new, more energy-efficient Grundfos pumps was approved, and the install was carried-out with minimal disruption to the customer’s operation.
"A COMPLETE PAYBACK ON THE INITIAL INVESTMENT WAS SECURED WITHIN A LITTLE OVER 18 MONTHS."
The Result
By replacing three pump units at the power station, the customer has reduced their electricity consumption by 594048 kWh per year. This translates to a significant annual cost-saving of £56,435 being enjoyed. With the new pumps costing around £95,000, a complete payback on the investment was secured within a little over 18 months. Environmental benefits were also secured as a result of the work, with the customer reducing their carbon footprint at a rate of 245 tonnes of CO2 per year.
