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.

Monitoring Water Banks with Telemetrics

Longstanding droughts across South Australia are forcing farmers to rethink the moisture in the soil they once regarded as their inalienable right. Trend monitoring is an essential input to applying pesticides and fertilisers in balanced ratios. Soil moisture sensors are transmitting data to central points for onward processing on a cloud, and this is making a positive difference to agricultural output.

Peter Buss, co-founder of Sentek Technology calls ground moisture a water bank and manufactures ground sensors to interrogate it. His hometown of Adelaide is in one of the driest states in Australia. This makes monitoring soil water even more critical, if agriculture is to continue. Sentek has been helping farmers deliver optimum amounts of water since 1992.

The analogy of a water bank is interesting. Agriculturists must ?bank? water for less-than-rainy days instead of squeezing the last drop. They need a stream of online data and a safe place somewhere in the cloud to curate it. Sentek is in the lead in places as remote as Peru?s Atacamba desert and the mountains of Mongolia, where it supports sustainable floriculture, forestry, horticulture, pastures, row crops and viticulture through precise delivery of scarce water.

This relies on precision measurement using a variety of drill and drop probes with sensors fixed at 4? / 10cm increments along multiples of 12? / 30cm up to 4 times. These probe soil moisture, soil temperature and soil salinity, and are readily re-positioned to other locations as crops rotate.

Peter Buss is convinced that measurement is a means to the end and only the beginning. ?Too often, growers start watering when plants don’t really need it, wasting water, energy, and labour. By monitoring that need accurately, that water can be saved until later when the plant really needs it.? He goes on to add that the crop is the ultimate sensor, and that ?we should ask the plant what it needs?.

This takes the debate a stage further. Water wise farmers should plant water-wise crops, not try to close the stable door after the horse has bolted and dry years return. The South Australia government thinks the answer also lies in correct farm dam management. It wants farmers to build ones that allow sufficient water to bypass in order to sustain the natural environment too.

There is more to water management than squeezing the last drop. Soil moisture goes beyond measuring for profit. It is about farming sustainably using data from sensors to guide us. ecoVaro is ahead of the curve as we explore imaginative ways to exploit the data these provide for the common good of all.

How Energy Management Software Benefits Your Business

We’re in an era of price volatility in gas and electricity prices, coupled with greater scrutiny on the environmental impact of businesses in their day-to-day operations. According to the Department of Energy & Climate Change, the average SME can slash its energy bill by 18-25% simply by installing energy efficiency solutions in their facility.

Are you looking to improve energy use in your business? Prevent wastage, track consumption, identify opportunities to save on energy and reduce your carbon footprint while at it? It can be a daunting process to do it all manually. Taking those meter readings, preparing spreadsheets and combing through quotes and energy bills to validate them – this is not something you should be enduring in this day and age. Not when there are dedicated systems built for the task. That’s where Energy Management Software (EMS) comes in.

Importance Of Energy Management Software

Wasted energy = Wasted money

Failing to improve energy efficiency is costing SMEs loads of funds, with it coming to between £5,801 and £12,109 of missed annual savings for individual businesses. These are 18% – 24% of their energy costs. Where do you stand?

Take timers and thermostats for instance. When not properly set and controlled, or even simply forgetting to turn them down when not in the room, it can easily lead to unnecessary costs. How often do your staff forget to turn off the air conditioning when they leave the meeting rooms? Do you account for weekends or bank holidays when setting the controls of the AC? Mistakes like turning the temperature high on the thermostat to “quickly warm the room” are common, yet heating costs go up by about 8% with every 1°C rise.

There are installations that you can make to minimize wastage. For example, the Chinese Contemporary Arts Centre in Manchester is able to save £4,363 annually just by having a £100 timer installed to its heating system.

Some energy saving measures won’t even cost you a penny. For instance, did you know that you can save up to 30% of your heating costs simply by preventing cold air from entering the building? This means not keeping the doors just open for convenience. So how can you find points of weakness and areas of improvements in your facility? Install an EMS.

While businesses vary from one industry to the next, energy management basically boils down to:

Metering systems where the consumption is recorded
Determining how much energy can be saved by identifying opportunities for this
Implementing policies and changing existing systems to take advantage of these opportunities
Tracking progress after the improvements have been made

Benefits Of EMS For Your Business

Data Acquisition – Where accuracy and reliability matters

Energy data comes from different angles and formats. From the building automation systems and IoT devices that have been set up, bills sent in by the utility company to the spreadsheets needed to analyse them – what if you had it all from one point of reference? The EMS gives you a “bird’s eye view” of all your energy data from one interface. It collects the data from any system – and being cloud-based, is accessible from anywhere in the world.

The ecoVaro data loggers can be connected with the Wi-Fi network of the facility or function independently, depending on your specific requirements. They monitor readings 24/7, retaining the data even when they have been powered off. The end-to-end encryption assures you of the security of the information that is being obtained.

Integrating the EMS into the existing systems will simplify the data collection process, and even for the cases where there isn’t a direct method transferring the data into the system, the setup wizards that come with the EMS allow you to prepare the required data and import it.

Data Analysis: From consumption, energy leaks to areas of improvement

The first step is accurately collecting the data. The next step is making sense of it. The analysis modules with the EMS allow you to monitor the energy consumption of the facility in real-time.

The energy data is displayed in engaging graphics that are easy to understand at a glance. The dashboard setup, with its customised layout, enables you to monitor the performance of the specific information you want, toggling through usage and savings data, to the meters and sites that are being tracked. With the ecoVaro Energy Management Software, you get Consumption Charts, Regression Charts, Cusum Charts and Heatmaps right to the submeter level. This information can be broken down into 15-minute durations, with the daily, weekly and monthly consumption reports.

Getting everyone on board

Making changes to company-wide energy policies needs to have the different parties on board – from the energy manager in charge of crunching the numbers and presenting the information, the CFO of the business, the staff running day-to-day operations, all through to plant operators for those in industries. An easy mode of communication is needed, that will be understood and availed in reports that can be shared with the relevant parties in the organization. The graphical displays that come with the EMS enable actionable information to be displayed in a simplified manner – that way all members of the business or organization will be able to comprehend it.

Meet your Energy Goals

The baseline that is created in the EMS is used as a standard when assessing the impact of future changes to the energy consumption. Using the information that has been obtained, the management can set up energy saving policies and implement changes, and track KPIs (key performance indicators) along the way. For instance, the market research company DJS Research installed a timer switch that turns off their two water coolers when they aren’t in use. This action saves them £144 annually, and had already paid for itself within 35 days.

You will be in a position to assess the actions that provide your business with the best ROI over time, monitoring the progress and verifying the savings from one central dashboard. Cutting costs here will enable you to divert the funds to other areas of your business, including promotions, marketing, and product development.

For businesses in the energy sector- including electric, oil and gas plants, they specifically need carbon emission reports, to pinpoint areas where the building’s energy efficiency can be improved. ecoVaro EMS allows you to set alarms and KPIs in the facility for issues to be identified and resolved immediately they crop up.

Turn to ecoVaro

EMS systems are used across the board – from optimising energy use in hotel rooms and hospitals, mapping out usage patterns for those in the agriculture and supply chain niches, running facilities for utility providers, all through to increasing the efficiency of equipment operation for business in the food and beverage sector.
