Whilst this subject is vast, this essential guide focuses on the key areas of energy management, helping to educate on common issues and provide clarity on the solutions needed to save time, energy and carbon footprint.<\/p>\n<\/div>

What does energy management really mean?<\/span><\/h3><\/h2><\/div>

The general consensus for energy management is simply turning things off and cutting your consumption, so why bother with an energy management system in the first place?<\/p>\n

Cutting production or service levels means sacrifice, not efficiency.<\/b><\/p>\n

The main objective of energy efficiency in industry is to continuously reduce energy consumption and associated costs whilst maintaining the same level of service or production.<\/p>\n

Energy efficiency = (services + goods + energy produced) \/ energy consumed<\/p>\n<\/div>

<\/span><\/div>

Energy management is not only about getting a cheaper rate and how much you can save with an energy supplier; it\u2019s about how much energy you consume, when you consume it and where it\u2019s being wasted. Understanding this and making small adjustments to your processes will have a huge impact on expenditure, ultimately leading to a more competitive business and better profitability.<\/p>\n<\/div><\/div><\/div>

<\/h2>\n

Did you know?<\/b><\/span><\/h4>\n<\/div>

There is a consumption peak on your energy usage, which you may not be aware of, once this limit is reached, you pay a penalty and automatically go on a much higher tariff. Without even realising it, your production costs suddenly rocket, and you start losing profitability.<\/p>\n<\/div><\/div><\/div>

<\/a><\/span><\/div><\/div><\/div>
<\/div><\/div>

What are the key areas that waste the most?<\/span><\/h2>\n<\/div><\/div><\/div>
<\/span><\/div>

Electric motors<\/h4>\n<\/div><\/div><\/div>
<\/span><\/div>

<\/span><\/div>

Workforce behaviour<\/h4>\n<\/div><\/div><\/div>
<\/div><\/div>

Understanding why, and how to offset waste<\/h2>\n

First, we need to understand what all the key energy cost areas are and where efficiencies can be made.<\/p>\n

<\/div>\n<\/div>
<\/span><\/div><\/div><\/div>

Electric motors<\/h2>\n

In industry, electric motors are the largest consumer of energy. Efficient motors and inverters help reduce energy usage, but this needs to be quantified in order to optimise the performance of the process.<\/p>\n

<\/div>\n<\/div>
<\/a><\/span><\/div>
Common practices found are fans, compressors and pumps are left running continuously instead of only when needed and at the best time; even substation transformers are running when not required. Simply switching these off when they are not being used will immediately save considerable amounts of energy and money.
\n<\/b><\/div>\n
<\/div>\n<\/div><\/div><\/div>

<\/h2>\n

Reduce reactive power?<\/b><\/span><\/h4>\n<\/div>

All motors require two kinds of power to operate: Active Power
\n(kW (kilowatts)), which is the power to produce the motive force, and Reactive Power (kVAr (kilo-volt-amperes reactive)), which energises the magnetic field.<\/p>\n

To work out the efficiency of a motor and how much you are actually paying for, you combine the two values to give you the Apparent Power (kVA (kilo-volt-amperes)).<\/p>\n

Would you be happy to pay for the full Apparent Power, knowing you are only using the Active Power element?<\/b><\/p>\n

To correct the Reactive Power used, capacitors can be locally connected. These capacitors help to balance the Reactive Power to meet the demand of the inductive loads. This will keep that Reactive Power from having to flow all the way from the utility generator to the load, saving energy and money on every electric motor. Using an effective monitoring system can identify which areas require preventative solutions.<\/p>\n<\/div><\/div><\/div>

<\/span><\/div><\/div><\/div>
<\/div><\/div>
<\/span><\/div>

Machinery wear and tear<\/h2>\n

Why does machinery wear and tear use more energy?<\/b>
\nMachinery wear and tear result in increased energy usage due to several key factors:<\/p>\n

<\/div>\n<\/div><\/div><\/div>
<\/span><\/div>

Increased friction<\/b>: Worn-out components develop rough surfaces, leading to higher friction between moving parts. This friction requires more energy to overcome, increasing overall energy consumption.<\/p>\n<\/div><\/div><\/div>

<\/span><\/div>

Loss of lubrication efficiency<\/b><\/span>: Degraded or contaminated lubricants fail to reduce friction effectively. Inefficient lubrication means more resistance and energy needed for smooth operation.<\/p>\n<\/div><\/div><\/div>

<\/span><\/div>

Component degradation<\/b><\/span>: Worn parts such as gears and bearings do not function efficiently. This inefficiency means the machinery has to work harder, consuming more energy to maintain the same performance level.<\/p>\n<\/div><\/div><\/div>

<\/span><\/div>

Heat generation<\/b><\/span>: Increased friction generates extra heat, wasting energy. Additionally, cooling systems must work harder to maintain safe temperatures, using even more energy.<\/p>\n<\/div><\/div><\/div>

<\/span><\/div>

Vibration and noise<\/b><\/span>: Wear and tear cause imbalances and misalignments, leading to more vibrations and noise. These vibrations create additional resistance, requiring more energy to operate the machinery.<\/p>\n<\/div><\/div><\/div>

Identifying wear and tear is essential in proactive maintenance to optimise energy efficiency and extend equipment lifespan. An energy monitoring system can highlight where efficiencies are degrading early, so maintenance, repair or replacement can be planned in advance to reduce costly downtime.<\/p>\n<\/div><\/div><\/div>

<\/div><\/div>
<\/span><\/div>

Peak production times<\/h2>\n

Businesses that exceed their agreed peak energy usage or maximum demand levels may face several consequences:<\/p>\n

<\/div>\n<\/div><\/div><\/div>

Excess capacity charges<\/b>:
\nApplied for using more than the agreed maximum demand.<\/p>\n

<\/div>\n<\/div><\/div><\/div>

Excess capacity charges<\/b>:
\nApplied for using more than the agreed maximum demand.<\/p>\n

<\/div>\n<\/div><\/div><\/div>

Penalty charges<\/b><\/span>:
\nImposed by some suppliers to encourage better energy management.<\/p>\n

<\/div>\n<\/div><\/div><\/div>

Higher tariffs for exceeding peak usage<\/b>: Businesses
\nmay be subject to higher tariffs if they exceed peak usage limits.<\/p>\n

<\/div>\n<\/div><\/div><\/div>

Managing peak energy usage<\/b><\/span><\/p>\n

Knowing your limits and having the ability to monitor usage can help plan load shifts to avoid penalties and higher tariffs, making each production run as efficient and profitable as possible. Another important benefit from understanding and monitoring energy usage is more accurate job costing and competitiveness.<\/p>\n

<\/div>\n<\/div><\/div><\/div>
<\/span><\/div><\/div><\/div>
<\/div><\/div>
<\/span><\/div>

Solar power panels underutilised<\/h2>\n

Utilising solar power to reduce energy bills and reducing carbon footprint has great appeal for many businesses. Solar generated energy is classed as green energy, so it counts towards Net Zero targets and once the investment is paid off, it\u2019s free energy\u2026 or is it?<\/p>\n

Whilst there is a big initial cost, once installed (and depending on energy usage), a business may see a Return On Investment in around 15 years. However, most will not see anywhere near that ROI because most of the energy generated ends up back in the National Grid for a tiny buy back cost.<\/p>\n

<\/div>\n<\/div>

Why can\u2019t you use all of the energy used from solar?<\/b><\/p>\n

Essentially, the energy produced is on demand, so whilst the sun is bright and production is running, the business is benefiting from some renewable energy. Usually, the demand for energy is higher than the production and any energy generated before or after this period cannot be stored, and so is put back into the National Grid for minimal return.<\/p>\n

<\/div>\n<\/div><\/div><\/div>
<\/span><\/div><\/div><\/div>

So, what\u2019s the answer?<\/b><\/p>\n

If you have the ability to monitor solar panel energy peaks, you can then plan production shifts to take advantage of more cost-effective energy. This not only improves production profitability, but also reduces the ROI on the initial investment.<\/p>\n

<\/div>\n<\/div><\/div><\/div>
<\/div><\/div><\/div><\/div>
<\/span><\/div>

Workforce behaviour<\/h2>\n

This is the quickest fix of all: a simple cultural change in the workplace, so everyone in the business switches off power anywhere it\u2019s not being used, and the business automatically saves \u00a31000s every year.<\/p>\n

<\/div>\n<\/div><\/div><\/div>

If you already have an energy management system in place, it should be able to prove these savings in real time. Sharing these results with the workforce can reinforce the importance of these small changes, provide better job security and a healthier cash flow to re-invest into the business for a better future for everyone.<\/p>\n

Benefits of integrating ISO 50001 with sustainability reporting-main heading<\/h2>\n

In the realm of sustainability reporting, integrating ISO 50001, the international standard for energy management systems, can significantly enhance the effectiveness and credibility of sustainability initiatives within an organisation.<\/p>\n

ISO 50001 provides a structured framework for establishing, implementing, maintaining, and improving energy management practices, leading to a range of benefits that complement and strengthen sustainability reporting efforts.<\/p>\n

Read more on ISO 50001<\/a> in our sustainability post.<\/p>\n

<\/div>\n<\/div>
<\/span><\/div>

Compulsory energy reports<\/h2>\n

If your business uses 40,000kWh or more, you will be required to provide Streamlined Energy and Carbon Reporting (SECR). The UK Financial Conduct Authority (FCA) requires companies with UK-listed shares to complete mandatory annual Task Force for Climate-Related Financial Disclosure (TCFD) aligned climate disclosure reporting.<\/p>\n

<\/div>\n<\/div><\/div><\/div>

Department for Energy Security and Net Zero requires UK-registered companies with over 500 employees or \u00a3500 million in annual revenue to complete annual sustainability and climate related disclosure reporting.<\/p>\n

Hopefully this has given you food for thought on why managing energy and making efficiencies is essential to the continued success and profitability of your business. The next section talks about how a good energy management system works and the real benefits it brings to your business.<\/p>\n
