Saving Energy Step 3 ? Towards a Variable Energy Bill

Do you remember the days when energy was so cheap we paid the bill almost without thinking about it? Things have changed and we have the additional duty of reducing consumption to help save the planet. This is the third article in our mini-series on saving energy. It follows on from the first that explored implementing a management system, and the second listing practical things to implement on the shop floor. These open up the possibility of the variable energy bill we expand on as follows.

If ?variable energy bill? sounds strange to you, I used the unusual turn of phrase to encourage you to view things in a different light. We need to move on from the ?pie chart? mentality where we focus on the biggest numbers like materials, facilities and labour, and zoom in on energy where we can achieve similar gains faster with less pain. But first, we need to see beyond the jargon that governments and consultants love, and get to grips with the reality that we can vary our energy bill and bring cost down.

As executives we recognise this, although other pressures distract us from accepting it as a personal goal. And so we delegate it down the organisation to a level where it becomes ?another crazy management idea? we have to follow to stay out of trouble. I read somewhere that half the world?s organisations do not have energy as a defined objective to monitor in the C Suite. No wonder commerce is only pecking away at energy wastage at a rate of 1% per year.

Find out where you are ?spending energy? and relate this to your core business. If there are places where you are unable to make a connection, challenge the activity?s right to exist. Following the energy trail produces unexpected benefits because it permeates everything we do.

  • Improved product design reducing time spent in factory
  • Streamlined production schedules reducing machine run times
  • Less wear on equipment reducing costly maintenance
  • A more motivated workforce that is prouder of ?what we do?

As you achieve energy savings you can pass these on in terms of lower prices and greater market share. All this and more is possible when you focus on the variables behind your energy bill. Run the numbers. It deserves more attention than it often gets.

Failure Mode and Effects Analysis

 

Any business in the manufacturing industry would know that anything can happen in the development stages of the product. And while you can certainly learn from each of these failures and improve the process the next time around, doing so would entail a lot of time and money.
A widely-used procedure in operations management utilised to identify and analyse potential reliability problems while still in the early stages of production is the Failure Mode and Effects Analysis (FMEA).

FMEAs help us focus on and understand the impact of possible process or product risks.

The FMEA method for quality is based largely on the traditional practice of achieving product reliability through comprehensive testing and using techniques such as probabilistic reliability modelling. To give us a better understanding of the process, let’s break it down to its two basic components ? the failure mode and the effects analysis.

Failure mode is defined as the means by which something may fail. It essentially answers the question “What could go wrong?” Failure modes are the potential flaws in a process or product that could have an impact on the end user – the customer.

Effects analysis, on the other hand, is the process by which the consequences of these failures are studied.

With the two aspects taken together, the FMEA can help:

  • Discover the possible risks that can come with a product or process;
  • Plan out courses of action to counter these risks, particularly, those with the highest potential impact; and
  • Monitor the action plan results, with emphasis on how risk was reduced.

Key Steps to Complying with ESOS

Energy Savings Opportunity Scheme has already been launched. In fact, it is by now in its initial phase. However, many businesses are still not aware of the new scheme, especially those who are covered by the qualifications for ESOS. To help them understand what they need to do in compliance to the energy efficiency strategy, here are key steps they can follow along the way.

Measure Overall Energy Consumption

The first step to complying with ESOS is to make an initial estimate of the business? energy consumption. This includes measuring the use of electricity, renewable energy, combustible fuels and all other forms of energy consumed whether in buildings, transports and industrial processes.

Three important factors to consider are the measurement units used, the reference period and quality of data. Energy units, such as MWh and GJ, or energy expenditure costs should be applied. Business enterprises should also do the initial measurement within a reference period of 12 months. Moreover, data collected should be verifiable at hand.

Identify Areas of Significant Energy Consumption

When the total energy consumption for all the activities and assets has already been estimated, it’s then time to identify what areas in the organisation comprise the significant portion of the overall energy usage. The areas recognised should cover at least 90% of the overall consumption. Meaning to say, ESOS participants have the chance to omit 10% of the energy consumption and instead focus on the 90%. This would ensure that subsequent energy audits will be cost-effective and proportionate.

Consider and Choose Compliance Routes

In order to comply with ESOS, qualified businesses should consider what compliance routes to take. These routes include taking series of energy audits, operating and implementing a certified ISO 50001 energy management system, acquiring Display Energy Certificates (DECs) and working with Green Deal assessments. Whichever route the business takes, one should maintain credible evidences, along with helpful documents, to certify their compliance.

Report the Compliance

Except when the large enterprise covers all the significant areas of energy consumption by means of ISO 50001 certification, one should appoint a lead assessor to supervise, conduct and review the organisation’s chosen ESOS compliance route. In this case, the approved assessments should then be signed off at board level to ensure that the conclusions and recommendations for energy savings are properly carried. To confirm their compliance, the business should submit a formal notification to the Environment Agency.

Because ESOS is not just an opportunity but also an obligation, it designated compliance bodies and gave them the authority to file civil penalties towards those who fail to comply with the scheme. Not only that, these appropriate authorities have the right to publish information about non-compliant enterprises including their name, details of non-compliance and corresponding penalty amount. Among these UK compliance bodies are Natural Resources Wales, Environment Agency in England, The Scottish Environment Protection Agency (SEPA) and Northern Ireland Environment Agency.

So, if you are covered with the ESOS qualifications, make sure to be informed. As the famous saying goes, ?Ignorance of the law excuses no one.? Likewise, awareness of ESOS is a responsibility every large business in UK should give importance to.

Energy efficiency- succeed and benefit

Energy is neither created nor destroyed; it is only transformed. This being the law of conservation of energy, and given that the process of transforming energy is inefficient resulting in loss of usable energy in the process of transforming one form of energy into another form, Energy Efficiency finds a home.
Talking of Energy efficiency, think of how much useful energy can be obtained from a system or a particular technology. It is also about the use of technology that requires a lesser amount of energy to carry out the same task.

Energy efficiency is the responsibility of both demand side and supply side. Supply-side energy efficiency refers to a set of actions taken to ensure efficiency through the electricity supply chain. Supply side efficiency measures are about efficiency in electricity generation; be it operation and maintenance of existing equipment or upgrading existing equipment with state-of-the-art energy-efficient generating equipment.

The demand side energy efficiency on the other hand refers to the actions taken to use less/demand less energy. Think of less energy usage in relation to improvement of energy efficiency in buildings, solar water heaters, energy efficient lighting systems such as Compact Fluorescent Lamps, conducting energy audits to identify potential energy saving opportunities, efficient water heating systems and the list is endless.

Success of energy efficiency is a win ? win to YOU-ME-US – the energy consumers, to THEM the energy producers and suppliers and to our precious ENVIRONMENT.
Gain to energy suppliers: – Less energy usage and better energy usage patterns among consumers consequently reduces the customer load which reduces losses on the supply side. Less energy loss creates capacity on the system to serve more customers.

Gain to you-me-us: – Less energy usage and better energy usage patterns Benefits the customer through reduced Electricity bills / $ savings through lower bills.

Benefits to the environment: – Usage of less energy reduces use of fossil fuels, hence reduction in GHG emissions hence conserving our environment. Companies look at means to make rational use of their least efficient generating equipment. The objective is to improve the operation and maintenance of existing equipment or upgrade it with state-of-the-art energy-efficient technologies. Some companies have on-site electricity generation alternatives and thus tend to consider the supply side in addition to demand-side energy efficiency.
