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.

Energy Cooperation Mechanisms in the EU

While the original mission of the European Union was to bring countries together to prevent future wars, this has spun out into a variety of other cooperative mechanisms its founders may never have dreamed of. Take energy for example, where the European Energy Directive puts energy cooperation mechanisms in place to help member states achieve the collective goal.

This inter-connectivity is essential because countries have different opportunities. For example, some may easily meet their renewable targets with an abundance of suitable rivers, while others may have a more regular supply of sunshine. To capitalise on these opportunities the EU created an internal energy market to make it easier for countries to work together and achieve their goals in cost-effective ways. The three major mechanisms are

  • Joint Projects
  • Statistical Transfers
  • Joint Support Schemes

Joint Projects

The simplest form is where two member states co-fund a power generation, heating or cooling scheme and share the benefits. This could be anything from a hydro project on their common border to co-developing bio-fuel technology. They do not necessarily share the benefits, but they do share the renewable energy credits that flow from it.

An EU country may also enter into a joint project with a non-EU nation, and claim a portion of the credit, provided the project generates electricity and this physically flows into the union.

Statistical Transfers

A statistical transfer occurs when one member state has an abundance of renewable energy opportunities such that it can readily meet its targets, and has surplus credits it wishes to exchange for cash. It ?sells? these through the EU accounting system to a country willing to pay for the assistance.

This aspect of the cooperative mechanism provides an incentive for member states to exceed their targets. It also controls costs, because the receiver has the opportunity to avoid more expensive capital outlays.

Joint Support Schemes

In the case of joint support schemes, two or more member countries combine efforts to encourage renewable energy / heating / cooling systems in their respective territories. This concept is not yet fully explored. It might for example include common feed-in tariffs / premiums or common certificate trading and quota systems.

Conclusion

A common thread runs through these three cooperative mechanisms and there are close interlinks. The question in ecoVaro?s mind is the extent to which the system will evolve from statistical support systems, towards full open engagement.

Will UK Retailers Skim the Cream with ESOS?

The British Retail Consortium (BRC) was quick out on the starting blocks with an ambitious plan to cut energy costs by 25% in 5 years. Their ?25-in-5? initiative is chasing a target of ?4.4 billion savings during the duration. Part of this program involves ?cutting a path through a complex and inaccessible policy landscape?. BRC believes this drawback is making its members think twice about making energy efficiency investments.

The UK?s sprawling network of grocers, department stores and malls is the nation?s second most hungry energy customer, having spent ?3.3 billion on it in 2013 when it accounted for almost 20% of carbon released. If you think that sounds bad, it purchased double that amount in 2005. However the consortium believes there is still more to come.

It bases this assumption on the push effect of UK energy rates increasing by a quarter during the duration of the project. ?So it makes sense to be investing in energy efficiency rather than paying bills,? Andrew Bolitho (property, energy, and transport policy adviser) told Business Green. The numbers mentioned exclude third party transport and distribution networks not under the British Retail Consortium umbrella.

The ?complex and inaccessible policy landscape? is the reflection of UK legislators not tidying up as they go along. BRC cites a ?vast number of policies ? spreading confusion, undermining investment and making it harder to raise capital?. The prime culprits are Britain?s CRC Energy Efficient Scheme (previously Carbon Reduction Commitment) which publishes league tables and ESOS. Andrew Bolitho believes this duality is driving confused investors away.

The British Retail Consortium is at pains to point out that this is not about watering things down, but making it simpler for participating companies to report on energy matters at a single point. It will soon go live with its own information hub providing information for retailers wishing to measure consumption at critical points, assemble the bigger picture and implement best practice.

Ecovaro agrees with Andrew Bolitho that lowering energy demand and cutting carbon is not just about technology. We can do much in terms of changing attitudes and providing refresher training and this does not have to cost that much. Studies have shown repeatedly that there is huge benefit in inviting employees to cross over to our side. In fact, they may already be on board to an extent that may surprise.

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.
