How Mid-South Metallurgical cut Energy Use by 22%

Mid-South in Murfreesboro, Tennessee operates a high-energy plant providing precision heat treatments for high-speed tools – and also metal annealing and straightening services. This was a great business to be in before the energy crisis struck. That was about the same time the 2009 recession arrived. In no time at all the market was down 30%.

Investors had a pile of capital sunk into Mid-South?s three facilities spread across 21,000 square feet (2,000 square meters) of enclosed space. Within them, a number of twenty-five horsepower compressors plus a variety of electric, vacuum and atmospheric furnaces pumped out heat 27/7, 52 weeks a year. After the company called in the U.S. Department of Energy for assistance, several possibilities presented.

Insulate the Barium Chloride Salt Baths

The barium chloride salt baths used in the heat treatment process and operating at 1600?F (870?C) were a natural choice, since they could not be cooled below 1200?F (650?C) when out of use without hardening the barium chloride and clogging up the system. The amount of energy taken to prevent this came down considerably after they covered and insulated them. The recurring annual electricity saving was $53,000.

Manage Electrical Demand & Power

The utility delivers 480 volts of power to the three plants that between them consume between 825- and 875-kilowatt hours depending on the season. Prior to the energy crisis Mid-South Metallurgical regarded this level of consumption as a given. Following on the Department of Energy survey the company replaced the laminar flow burner tips with cyclonic burner ones, and implemented a number of other modifications to enhance thermal efficiency further. The overall natural gas reduction was 20%.

Implement Large Scale Site Lighting Upgrade

The 24/7 nature of the business makes lighting costs a significant factor. Prior to the energy upgrade this came from 44 older-type 400-watt metal halide fixtures. By replacing these with 88 x 8-foot (2.5 meter) fluorescent fittings Mid-South lowered maintenance and operating costs by 52%

The Mid-South Metallurgical Trophy Cabinet

These three improvements cut energy use by 22%, reduced peak electrical demand by 21% and brought total energy costs down 18%. Mid-South continues to monitor energy consumption at each strategic point, as it continues to seek out even greater energy efficiency in conjunction with its people.

Competencies, Roles and Responsibilities of Lead Assessors

Any organisation that opts for energy audits, Display of Energy Certificates and Green Deal Assessments needs a lead assessor to review the chosen ESOS compliance routes. The Derivative provides that energy audits should be carried out independently by qualified and accredited experts. Additionally, these audits should be implemented as well as supervised by independent authorities under the national legislation.

Lead assessors undertake several roles in ESOS assessments. He or she is the one responsible to take the lead of the entire assessment team, prepare the plan, conduct the meetings and submit the formal report to governing authorities. Nevertheless, selecting an appropriate lead assessor is an important element that every organisation should carefully consider.

Competencies Requirements of Lead Assessors

Lead assessors should be knowledgeable enough with in-depth expertise in carrying out energy efficiency assessment. They should also possess foundational, functional and technical competencies to deliver the task effectively. Likewise, consider the assessors? sector experiences, familiarity with your business? technologies and properties, and accreditation with prescribed standards.

As you choose your lead assessor, contemplate on the skills and qualifications that would give your organisation benefits.

Roles and Responsibilities of Lead Assessors

The business organisation is responsible for the overall legal ESOS compliance. Moreover, here are some of the roles and responsibilities that lead assessors should assume in ESOS assessments.

The lead assessor agrees on the audit methodologies that the organisation would undergo in new audits. He or she agrees with the ESOS participant regarding the audit timetable, sampling approach and visits required. It is also the lead assessor?s role to identify the opportunities on energy saving and assist in calculating the cost savings from the measures taken. During the ESOS audits, the lead assessor determines the energy use profiles, presents the recommendations and reviews the entire assessment as a whole. Furthermore, he or she should maintain the evidence pack of the ESOS to uphold the audit’s credibility, its findings and recommendations.

Finding Lead Assessors

Energy and environment professionals would only be able to demonstrate their expertise as lead assessors upon registering in a professional body accredited by the Environment Agency. Any business that needs a lead assessor is advised to check on the EA?s website to see the details of approved registers.

Lead assessors can either be in-house experts or external professionals. However, they should be able to provide proof of membership as an approved register to take the role of a lead assessor. If the organisation has an internal lead assessor, the company should then take the final ESOS assessment to two board-level directors that would sign the formal report.

Indeed, the lead assessor is an organisation’s partner when it comes to delivering great results. With good professional conduct and excellent management of an assessment team, the lead assessor can help achieve breakthrough energy efficiency strategies. More than anything else, the organisation will benefit from maximum energy savings opportunities ahead. Thus, every qualified business enterprise should invest in finding the best lead assessor to guide them towards success.

Big Energy Data Management

Recent times have seen the advent of cloud based services and solutions where energy data is being stored in the cloud and being accessed from anywhere, anytime through remote mobile devices. This has been made possible by web-based systems that can usually bring real-time meter-data into clear view allowing for proactive business and facility management decisions. Some web based systems may even support multi utility metering points and come in handy for businesses operating multiple sites.

Whereas all this has been made possible by increased use of smart devices/ intelligent energy devices that capture data at more regular intervals; the challenge facing businesses is how to transform the large data/big volume of data into insights and action plans that would translate into increased performance in terms of increased energy efficiency or power reliability.

A solution to this dilemma facing businesses that do not know how to process big energy data, may lie in energy management software. Energy management software?s have the capability to analyse energy consumption for, electricity, gas, water, heat, renewables and oil. They enable users to track consumption for different sources so that consumers are able to identify areas of inefficiency and where they can reduce energy consumption, Energy software also helps in analytics and reporting. The analytics and reporting features that come with energy software are usually able to:

? Generate charts and graphs ? some software?s give you an option to select from different graphs

? Do graphical comparisons e.g. generate graphs of the seasonal average for the same season and day type

? Generate reports that are highly customisable

While choosing from the wide range of software available, it is important for businesses to consider software that has the capacity to support their data volume, software that can support the frequency with which their data is captured and support the data accuracy or reliability.

Energy software alone may not make the magic happen. Businesses may need to invest in trained human resources in order to realise the best value from their big energy data. Experts in energy management would then apply human expertise to leverage the data and analyse it with proficiency to make it meaningful to one?s business.

Six Sigma

Six Sigma has received much attention worldwide as a management strategy that is said to have brought about huge improvements and financial gains for such big-name companies as Allied Signal, General Electric (GE) and Motorola.

If you want to give your business the chance to attain the same resounding success, Six Sigma could be the method that will steer you towards that direction.

What is Six Sigma?

So what really is it? Six Sigma is a business management tool that was developed using the most effective quality improvement techniques from the last six decades. Basing its approach on discipline, verifiable data, and statistical calculations, Six Sigma aims to identify the causes of defects and eliminate them, thereby resulting in near-perfect products that meet or exceed customer’s satisfaction.

The core concept behind the Six Sigma method is that if an organisation can quantify the number of “defects” there are in a particular process, improvement activities can be implemented to eliminate them, and get as close to a “zero defects” scenario as possible. Defect here is defined as any process output that fails to meet customer specifications.

Six Sigma is also unique from other programs in that it calls for the creation of a special infrastructure of people within the organisation (“Champions“, “Black Belts“, “Green Belts“) who are to be expert in the methods.

Six Sigma Methodologies

When implementing Six Sigma projects, two methodologies are often employed. Although each method uses five phases each, these two are distinguished from each other using 5-letter acronyms and their specific uses.

DMAIC ? is the project methodology used to improve processes and maximise productivity of current business practices. The 5 letters stand for:

  • D ? Define (the problem)
  • M ? Measure (the main factors of the existing process)
  • A ??Analyse?(the information gathered to deter mine the causes of defects)
  • I ? Improve (the current process based on the analysis)
  • C ? Control (all succeeding processes so as to minimise additional defects)

DMADV – is the method most suitable if your business is looking to create new products or designs. The acronym stands for:

  • D ? Define (product goals as the consumer market demands)
  • M ? Measure (and identify product capabilities and risks)
  • A ??Analyse?(to create the best possible design)
  • D ? Design (the product or process details)
  • V ? Verify (the design)

How does Six Sigma differ from other quality programs?

If you think that Six Sigma is just another one of those business strategies that produce more hype than actual results, think again. Six Sigma uses three key concepts that sets it apart from other business management methods.

  • It is strictly a data-driven approach, where assumptions and guesswork do not figure in the decision making.
  • It focuses on achieving quantifiable financial results ? the bottom line ($) ? as much as giving emphasis on customer satisfaction.
  • It requires strong management leadership, while at the same time creating a role for every individual in the organisation.

Is Six Sigma right for your business?

While many other organisations such as Sony, Nokia, American Express, Xerox, Boeing, Kodak, Sun Micro-systems and many other blue chip companies have followed suit in adopting Six Sigma, the truth is, any company — whether you have a large manufacturing corporation, or a small business specialising in customer service.

Certainly, there is a lot more to Six Sigma than what you can probably absorb in one sitting or reading.

With our wide range of business management consultancy services, we can help you understand the Six Sigma method in the context of your business. We can also help you establish your improvement goals, set up your program, and train your own team of “champions” who can lead in implementing your Six Sigma goals.
