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.?

2015 – What’s ahead for UK Business?

According to reports just in, the global environment industry is down. Less money is available for what some CEO?s still see as grudge expenditure, and many U.S. agencies are seeking soft budget cuts. The UK is proving to be an exception following the announcement of ESOS, and EcoVaro does not expect the May elections will have much impact in this regard.

ESOS calls for mandatory energy assessments in companies above a certain size, and requires specific proposals to cut consumption. There is no indication of compulsory follow-through, although it is clear the Environment Agency hopes rising electricity prices and the prospect of monetary savings will do the trick.

It is an open question whether the Tory government would have interfered with commerce to this extent, were it not for the European directive that enforced it. The overall goal is to cut EU energy consumption across the board by 20% by 2020. Energy consultants are rubbing their hands in glee. EcoVaro?s response is to provide cloud-based software.

We will be interested to see how many UK companies make the first deadline of 5 December 2015, in the light of reports that half the 9,000 firms affected appear not to even know that ESOS exists. Some will no doubt pay last-minute lip service. Those with an eye on their own sustainability will grasp the Energy Saving Opportunity Scheme with both hands.

The initial ESOS deadline was always going to be a challenge. Some big corporates have stolen a march albeit egged on by green stakeholders. The next challenge comes in June 2015 with the implementation of the European Union?s ?Waste Catalogue? of hazardous substances, and rules for their disposal. We hope a new ISO 14001 will arrive soon and pull the loose threads together.

The introduction of carbon trading late this year brings further opportunities to increase profits through wise stewardship. Auditable metrics are essential for this.

A Business Case for Sharing

We blogged about sharing services in a decentralised business context recently, and explained why we think why these should be IT-Based for speedy delivery. This is not to say that all shared services projects worldwide have been resounding successes. This is often down to the lack of a solid business case up front. We decided to lay out the logic behind this process.

Management Overview ? The overview includes a clear definition of why the current situation is unacceptable, the anticipated benefits of sharing, and an implementation plan were it to go ahead. The project should not proceed until the stakeholders have considered and agreed on this.

Alternatives Considered ? The next stage is to get closer to the other options in order to determine whether an alternative might perhaps be preferable. Substitutes for shared services are often doing nothing, improving the current method, and outsourcing the service to a third party.

The Bottom Line in Business ? Sharing services comes at an initial cost of infrastructure changes, and the impact on human capital (the latter deserves its own blog). The following need careful consideration from the financial angle:

Numbers to Work Through

  • Manpower to design and roll the project out in parallel with the existing organisation.
  • Capital for creating facilities at the central point including civil works, furniture and equipment and IT infrastructure.
  • The costs of travel, feeding and accommodation. These can be significant depending on the time that implementation takes.
  • The opportunity loss of diverting key staff – and the cost of temporary replacements – if appointing line staff to the project team.
  • Crystal-clear project metrics including (a) the direct, realisable savings (b) the medium and long-term effects on profit and (c) where to deploy the savings

Risk Management

Shared services projects don’t go equally smoothly, although planning should reduce the risk to manageable levels. Nonetheless it is important to imagine potential snags, decide how to mitigate them and what the cost might be.

We believe in implementing shared services on a pilot basis in the business unit that eventually provides them. We recommend building these out to other branches only when new processes are working smoothly.

Moving On From a Decision

We recommend you revisit your management overview, the logic behind it, the assumptions you made, and the costs and benefits you envisage before deciding to go ahead

The final step in proving a business case is doable should be fleshing out your roadmap into a detailed operations plan with dependencies on a spreadsheet.

The Cloud: Changing the Game for Small Businesses

There is a consensus among cloud experts that the onset of cloud computing will benefit small organisations the most. In fact, many even go as far as saying that the cloud and small businesses are a match made in IT heaven. How much of this is true and how much of this is merely part and parcel of the hype surrounding cloud computing?

The Cloud as the Great?Equaliser

If you closely examine the essential characteristics of cloud computing, particularly public cloud services, you will see why small organisations would be very interested in the cloud, and would eventually flock to it, like moths to a flame. And why not? Cloud computing is turning out to be the weapon that can allow small and medium organisations to compete on a more level playing field against large enterprises.

Here are some cloud computing benefits that may just close the gap between the two.

  • Significantly lower IT spending. With little to no investment at all on hardware infrastructure and practically zero maintenance costs, SMBs that would have required substantial capital for IT are now finding it easy to get a business started from scratch or develop and test out new products by using the cloud as the backbone of their IT set-up. The pay-as-you-go pricing scheme that cloud computing offers allows companies to start small and scale up as needed, or when the revenue starts coming in.
  • Higher employee productivity. Licensing fees for software applications can run high even if you don’t have a large staff. Good thing there are now a host of cloud-based office tools – word processors, spreadsheets, presentations, accounting systems, etc. – that can boost employee productivity without the corresponding costs that small businesses can ill afford. Plus, team members in remote locations can continue to collaborate with the rest through any internet-connected device in real time.
  • Easier, better communication. The easy accessibility of communication apps has also changed the way employees interact with fellow employees and more importantly, with customers. Whether through email, instant messaging, or social networks, cloud services have given individuals and businesses more ways of giving and getting feedback. The best thing about it is that most of these services don’t cost much or are even free, giving SMBs ample tools to create better products and improve service.
  • A Look at the Figures Many small businesses are already seeing the potential in the cloud, with SaaS (Software as a Service) applications most commonly used among the early adopters. These services include email and other communication apps, file sharing, and backup.

In a February 2012 Edge Strategies survey (commissioned by Microsoft) of 3,000 small businesses in the US, the following data came to light:

  • The number of small companies with 2 to 10 employees using paid cloud services will triple in the next three years;
  • Current cloud users report purchasing an average of 4 services in the cloud now and expect to use 6 in the future;
  • Fifty percent agree that cloud computing is going to become more important for businesses such as theirs.

Further, a survey of 323 SMBs recently released by social business site Spiceworks and sponsored by EMC reveals that from 48 percent at the start of 2012 and 28 percent a year ago, 62 percent of the businesses surveyed now use some type of cloud app.

What these numbers show is that cloud adoption among small and medium enterprises is starting to gain ground and for sure, more will do the same as understanding and awareness increase. Yes, these businesses should still perform their due diligence as there is no one-size-fits-all cloud solution. But for those companies who have managed to find the right cloud apps and services for their needs, it’s all sunny skies up ahead.
