Sub-metering Facilitates 45% Savings on Lighting Costs at Suzuki

Suzuki may still be best known in the UK as a motorcycle manufacturer, but with sales in 2013 topping more than 33,000 units the company is a major player in the car market too and is now well known as the small car experts. In fact, Suzuki is also a major UK supplier of ATVs (All Terrain Vehicles) and a wide range of outboard motors. As might be imagined the service and spare parts support for this diverse range of products represents a significant challenge and requires a large and sophisticated operation to maintain it.

Located in Milton Keynes, Suzuki's parts warehouse covers 13,000 sq metres and ships around 300 consignments every day. The combined office and warehouse space employs 145 people, and must provide a carefully controlled environment to maintain the valuable parts inventory in top condition.

The solution

It is therefore a challenge to keep energy costs and consumption as low as possible, and to maintain the smallest possible carbon footprint in line with Suzuki's global commitment to a low-carbon performance. Facilities Manager Hayley McCann is clear about how the job should be done, and the track record at the site fully supports her methodology.

"The starting point is good information" she says, and to that end Elcomponent were asked to supply a sub-metering system covering all the main electrical loads. Our MeterRing MM package was installed in early 2011 by Suzuki's electrical contractors Copper Veins Ltd, and quickly produced results as consumption was significantly reduced. "Initially it was a matter of good housekeeping really" reports Hayley "we cut out the waste, and ensured best practice..."

An excellent example of good housekeeping was the significant reduction in energy, cost & carbon which were achieved by optimising the yard lighting. Security and operational requirements meant that the area had to be adequately lit at all times, but the metering confirmed that in winter months the cost of doing so was running at close to £800 per month. Careful consideration of the necessary light levels and adjustment of the lighting controls was carried out to see if improvements could be realised without compromising the business. This resulted in savings to Suzuki of almost 45 per cent - over £2000 over a year.

The entire site is now undergoing assessment for an improved lighting scheme and again, the sub-metering package is seen as crucial to success. Whilst the yard lighting improvements was essentially a no cost/low cost project, the site-wide scheme will require replacement luminaires and new technology.

"This time we need the metering to evaluate the pilot installations to make sure the paybacks and savings match our projections. We like to make decisions based on facts wherever possible!"

is how the Facilities Manager puts it.

Wavin choose Elcomponent for Sub-Metering across UK and Ireland

Wavin are the UK's leading supplier of plumbing, heating and drainage systems to the construction and utilities markets, with a number of manufacturing locations in both the UK and Ireland.

The company's manufacturing processes include plastic extrusion, clay firing and other energy-intensive operations, and although it has invested heavily in new plant and equipment, it goes without saying that effective energy and carbon management are also key factors in its continued success. Good management requires good information however, and in this instance detailed energy and water consumption data are provided by extensive site-based automatic sub-metering systems supplied and installed by Elcomponent.

Elcomponent have delivered systems into four Wavin sites, comprising a total of over 140 meters which provide half hour readings in realtime to a central database. Data are managed and presented via Elcomponent's 'MeterRing MM' software and Wavin's own process-specific energy management routines. Installation involved meters for all three utilities and was achieved jointly between Elcomponent's installers and Wavin's in-house teams. The use of multiple networking options included VHF radio and the existing LAN, and utilised MODBUS connected meters where possible. This ensured that accuracy and reliability were combined with a cost-effective and efficient installation process, which was achieved with the minimum of disruption to the sites manufacturing processes.

Rai Gaidys, Elcomponent Lead Installer comments...

"Wavin run a very tight ship and we were working to a demanding timetable, but thanks to the professionalism of the client's engineering staff, and our new voltage output CT meters which speed up installation considerably, we were able to get the job done on schedule and with an absolute minimum of downtime"
