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 ESOS Guidelines Chapter 1 ? Who Qualifies

The base criteria are any UK undertaking that employs more than 250 people and/or has a turnover in excess of ?50 million and/or has a balance sheet total greater than ?43 million. There is little point in attempting to separate off high polluting areas. If one corporate group qualifies for ESOS, then all the others are obligated to take part too. The sterling equivalents of ?38,937,777 and ?33,486,489 were set on 31 December 2014 and apply to the first compliance period.

Representatives of Overseas Entities

UK registered branches of foreign entities are treated as if fully UK owned. They also have to sign up if any overseas corporate element meets the threshold no matter where in the world. The deciding factor is common ownership throughout the ESOS system. ecoVaro appreciates this. We have seen European companies dumping pollution in under-regulated countries for far too long.

Generic Undertakings that Could Comply

The common factor is energy consumption and the organisation’s type of work is irrelevant. The Environmental Agency has provided the following generic checklist of undertakings that could qualify:

Limited Companies Public Companies Trusts
Partnerships Private Equity Companies Limited Liability Partnerships
Unincorporated Associations Not-for-Profit Bodies Universities (Per Funding)

Organisations Close to Thresholds

Organisations that come close to, but do not quite meet the qualification threshold should cast their minds back to previous accounting periods, because ESOS considers current and previous years. The exact wording in the regulations states:

?Where, in any accounting period, an undertaking is a large undertaking (or a small or medium undertaking, as the case may be), it retains that status until it falls within the definition of a small or medium undertaking (or a large undertaking, as the case may be) for two consecutive accounting periods.?

Considering the ?50,000 penalty for not completing an assessment or making a false or misleading statement, it makes good sense for close misses to comply.

Joint Ventures and Participative Undertakings

If one element of a UK group qualifies for ESOS, then the others must follow suit with the highest one carrying responsibility. Franchisees are independent undertakings although they may collectively agree to participate. If trusts receive energy from a third party that must do an ESOS, then so must they. Private equity firms and private finance initiatives receive the same treatment as other enterprises. De-aggregations must be in writing following which separated ESOS accountability applies.

Quality Assurance

 

There is a truism that goes “The bitterness of poor quality is remembered long after the sweetness of low price has faded from memory”.

While every consumer can probably relate to this idea, business enterprises offering goods and services are the ones that should heed this the most.

Quality Management Systems

The concept of quality was first introduced in the 1800’s. Goods were then still mass-produced, created by the same set of people, with a few individuals assigned to do some “tweaking” on the product to bring it to acceptable levels. Their idea of quality at that time may not have been that well-defined, but it marked the beginnings of product quality and customer satisfaction as we know it now.

Since then, quality has developed into a very basic business principle that every organisation should strive to achieve. Yet while every business recognises the importance of offering product and service quality, it is not something that can be achieved overnight.

If you’ve been in any type of business long enough, you should know that there is no “quick-fix” to achieving quality. Instead, it is an evolving process that needs to be continually worked on. And this is where the importance of having a workable Quality Management System (QMS) in an organisation comes in.

Whatever Quality tools and processes you need to implement the change needed in your organisation, we can help you with it. We are ready to work in partnership with your team to develop strategic systems which will produce significant performance improvements geared towards the achievement of quality.

What is a Quality Management System?

A Quality Management System is defined as the set of inter-related objectives, processes, and operating procedures that organisations use as a guide to help them implement quality policies and attain quality objectives.

Needless to say, the ultimate goal of every quality management system is to establish quality as a core value of the company among all employees, and across all products and services. Why? Because quality services make for happy customers, and satisfied customers ensure continued business for the company.

A Quality Management System does not stop with simply having a set of guidelines that the leaders of a company can easily have their organisation members accept and adhere to. Rather, effective QMS can be implemented when management provides a culture of pride and patience, which will inspire acceptance of individual and group responsibility.

In this manner, not only the heads of the organisation but the employees as well, will develop the desire to achieve company goals that will benefit:

  • All contributing teams;
  • The customers; and
  • The company as a whole.

Saving Energy Step 1 ? Implementing a Management System

There has been much hype down the years regarding whether management is art or science. Thankfully, where people are concerned the pendulum has swung away from standard times in sweatshops in the west. However, when it comes to measuring physical things like harvest per square meter and the amount of energy consumed there is no substitute for scientific measurement, and this implies a system.

Managing energy cost and consumption down is like any other strategy. American engineer / statistician / management consultant W. Edwards Demming may have passed on in 1993. However he was as right as ever when he said:

  1. When people and organizations focus primarily on quality, this tends to increase and costs fall over time.
  1. However, when people and organizations focus primarily on costs, costs tend to rise and quality declines over time.

Demming believed that 90% of organizational problems arise from systems we put in place ourselves. This can be because we are so accustomed to them that we fail to notice when they are no longer relevant. The currently prevailing laissez faire towards energy is a case in point. What is managed improves and what is not, deteriorates. We know this. Let us take a look at how to apply this principle to energy management.

First, you need to get the subject out the closet and talk about it. How often do you do this is your boardroom, and how does energy rank against other priorities? Good governance is about taking up a position and following through on it. Here is a handy checklist you may like to use.

  • Do we use a consistent language when we talk about energy? Is it electricity, or carbon emitted (or are we merely fretting over cost).
  • How well engaged are we as a company? Looking up and down and across the organization are there points where responsibility stops.
  • How well have we defined accountability? Do we agree on key performance areas and how to report on them.
  • Are we measuring energy use at each point of the business? When did we last challenge the assumption that ?we’re doing okay?.
  • Have we articulated our belief that quality is endless improvement, or are we simply chasing targets because someone says we should.

A management system is a program of policies, processes and methods to ensure achievement of goals. The next blog focuses on tools and techniques that support this effort.
