What Sub-Metering did for Nissan in Tennessee

When Nissan built its motor manufacturing plant in Smyrna 30 years ago, the 5.9 million square-foot factory employing over 8,000 people was state of art. After the 2005 hurricane season sky-rocketed energy prices, the energy team looked beyond efficient lighting at the more important aspect of utility usage in the plant itself. Let’s examine how they went about sub-metering and what it gained for them.

The Nissan energy team faced three challenges as they began their study. They had a rudimentary high-level data collection system (NEMAC) that was so primitive they had to transfer the data to spread-sheets to analyse it. To compound this, the engineering staff were focused on the priority of getting cars faster through the line. Finally, they faced the daunting task of making modifications to reticulation systems without affecting manufacturing throughput. But where to start?

The energy team chose the route of collaboration with assembly and maintenance people as they began the initial phase of tracking down existing meters and detecting gaps. They installed most additional equipment during normal service outages. Exceptions were treated as minor jobs to be done when convenient. Their next step was to connect the additional meters to their ageing NEMAC, and learn how to use it properly for the first time.

Although this was a cranky solution, it had the advantage of not calling for additional funding which would have caused delays. However operations personnel were concerned that energy-saving shutdowns between shifts and over weekends could cause false starts. ?We’ve already squeezed the lemon dry,? they seemed to say. ?What makes you think there?s more to come??

The energy team had a lucky break when they stumbled into an opportunity to prove their point early into implementation. They spotted a four-hourly power consumption spike they knew was worth examining. They traced this to an air dryer that was set to cyclical operation because it lacked a dew-point sensor. The company recovered the $1,500 this cost to fix, in an amazing 6 weeks.

Suitably encouraged and now supported by the operating and maintenance departments, the Smyrna energy team expanded their project to empower operating staff to adjust production schedules to optimise energy use, and maintenance staff to detect machines that were running without output value. The ongoing savings are significant and levels of shop floor staff motivation are higher.

Let’s leave the final word to the energy team facilitator who says, ?The only disadvantage of sub-metering is that now we can’t imagine doing without it.?

Eck Industries Sheds Fresh Light

William Eck began his business in 1948 in a 650m2 garage building. The aluminium foundry prospered, and now has an 18,500m2 factory in Manitowoc, Wisconsin employing 250 people casting a variety of casings. Like high-tech industries around the globe it needs effective illumination. After it measured its carbon footprint, it realised it needed energy efficient lighting too.

When Eck Industries began its review it had around 360 high-pressure sodium lights throughout the plant. Their operating cost was substantial. After taking independent advice from an independent agency they realised they needed to replace these with more energy-efficient fluorescent lights that consume half as much energy.

The feasibility team conducted performance tests to determine the optimum solution. After selecting enclosed, gasketed and waterproof T8 fluorescents (available in G13 bipin, single pin and recessed double contacts) they collaborated with the supplier to calculate the best combination of 4 and 6 bulb fixtures.

The fittings they chose cost $60,000 plus $10,000 installation. However a $33,000 energy rebate wrote down 47% of this immediately. They achieved further energy savings by attaching motion sensors to lights over low-traffic walkways.

The retrofit was a huge success, with an 8 month payback via a direct operating saving of $55,000 a year. Over and above enhanced illumination Eck Industries slashed 674,000 kilowatt hours off its annual lighting bill. During the 20 year design life, this equates to a total 13.5 million kilowatt hours. Other quantifiable benefits include 443 tons less carbon, 2 tons less sulphur dioxide, and 1 ton less nitrogen oxide per year.

Many companies face similar opportunities but fail to capitalise on them for a number of reasons. These may include not being aware of what is available, lacking technical insight, being short of working capital and simply being too busy to focus on them.

Eck Industries got several things right. Firstly, they consulted an independent specialist; secondly they trusted their supplier to provide honest advice, and thirdly they accepted that any significant saving is worth chasing down. Other spin-offs were safer, more attractive working conditions and an opportunity to take their foot off the carbon pedal. This is an excellent example of what is possible when you try.

If you have measured your illumination cost and are concerned about it (but are unsure what the metric means within the bigger picture) then Ecovaro offers online reports comparing it with your industry average, and highlights the cost-benefits of alternative lighting. 

Top 3 reasons to get into Multi-Channel Retail

Multi-channel retail, which nowadays understandably includes online channels, is something you just have to do this year. Every single day you put off doing it, the competition gobbles up market share that should have been yours. There are a number of reasons why even successful retailers are now going into multi-channel retailing. Here?s three of the most important ones.

1. You’ll get a BIG jump in sales

Not counting this year, which could be getting a big boost from major activities like the Queen?s Diamond Jubilee and the 2012 Olympics, sales of UK retailers have been experiencing tremendous growth particularly from their online channels. Already two years ago (2010), a number of UK retailers boasted significant increases in sales as a result of multi-channel retail initiatives. These retailers included:

  • Argos, which got a whopping ?1.9bn from multichannel sales back then;
  • House of Fraser, which reported a 150% jump in its online sales in just 6 months; and
  • Debenhams, whose profits rose by 20%

There were many others. Now, the reason I?m showing you 2010 figures is because online retail sales increased by 14% in 2011 and those same businesses still added to that growth. So, if only you had enough foresight and started expanding your business to the Web two years ago, you could just imagine what your sales would have been today.

The good news is that, it’s not yet too late if you start now. Here?s why…

2. Those numbers are going to keep on growing

We’re getting all sorts of predictions from leading researchers regarding the possible growth of the Internet economy. All these predictions have one thing in common. They all have a positive outlook. The Boston Consulting Group (BCG), for instance, predicts an average growth of no less than 10% per year in the G-20 nations.

3. Most online retailers aren’t doing it right yet

Although many retailers have already started bringing their business to the Web, most of them are doing it the wrong way. For example, many of them fail to integrate their offline and online channels. This is a serious shortcoming because it leads to customer dissatisfaction.

When a customer goes to your website and sees something he likes, you wouldn’t want him to drive all the way to your store only to find out that the item isn’t available there or, if the item is there, that it isn’t priced as he expected. The lack of multi-channel integration is very common among multi-channel retailers.

These inadequacies are actually good news because it means there are still many areas you can improve on. After improving on them, you can then highlight those areas as your key differentiators.

Shared Services ? Are They A Good Idea

Things happen fast in business and we need to stay on top. It does not seem long ago that some enterprises were still hands-on traders or artisans with a few youngsters to help out. People like that did not do admin and their accounting was a matter of making sure there was enough money in the jar.

When Wal-Mart’s Sam Walton took over his first shop in 1945 things had moved on from there, although he did still deal directly with his customers. When he died his legacy was 380,000 jobs, and a business larger than most economies. So there?s plenty we can learn from how he grew his business.

One of Sam?s secrets was his capacity to centralise what needed gathering together, while empowering store managers to think independently when it came to local conditions. His regional warehouses had individual outlets clustered around them within one day?s drive each. This shared service eliminated 90% of safety stock and released capital for expansion.

Wal-Mart took sharing services a step further in February 2006, when it centralised accounts payable, accounts receivable, general accounting and human resources administration at Wal-Mart Stores and Sam?s Clubs in the U.S. and Puerto Rico. The objective was to bring costs down, while allowing local managers more time to focus on their business plans and other initiatives. As a further spin-off, Wal-Mart was able to integrate its data on a single SAP platform and eliminate significant roadblocks.

This is an excellent example of sharing services by creating own centres of excellence.? Of course, this is not the only business possibility. Other corporates have successfully completely outsourced their support activities, and Wal-Mart has no doubt had a variety of similar offers too. But, is the Wal-Mart picture entirely rosy, or is there a catch?

The Association of Chartered Certified Accountants has indicated that top talent may be the loser globally. This is because the Wal-Mart model removes many challenges through standardisation, and offers less scope for internal promotion as a result. Language and cultural differences may also have a long-term detrimental effect on the way the departments work well together.

Local outsourcing ? this is the business model where several firms engage a shared service provider independently- may hence prove to be a more malleable option for smaller companies. It often makes more sense to hunt down made-to-order services. Offerings such as the professional support we offer on this site.
