ENERGY MANAGEMENT FEATURE
WHO IS JUDGING YOUR energy saving measures?
industrial consumption. The objective of the ESOS programme is to build on the EU Energy Trading Scheme and provide UK industry with further reason to change operational practices. For government, the benefits are not
only in energy security but in meeting its commitment to cut greenhouse gas emissions by 80% of its 1990 baseline by 2050. To do this DECC states that energy efficiency will have to increase across all sectors to the extent that energy use per capita is between a fifth and a half lower than it is today. There is no doubt that an ESOS-style
With details of a new energy savings scheme to be announced in June, Paul West of Minimise Energy offers a few pointers
I
am not sure that anyone likes a government enforced audit except perhaps when it helps cut operational costs. That is exactly the point of the Energy Savings Opportunity Scheme (ESOS), details of which will be announced in June. All large enterprises in the UK will by
law have to undertake an energy audit which will have to be repeated every four years. Businesses with more than 250 employees or an annual turnover of more than 50 million euros will need to comply. However, rather than viewing this scheme as an unwelcome means of complying with EU energy legislation, think of this as a timely (and regular) reminder of the positive benefits that accrue from reducing energy use and costs. The principles shouldn’t be the preserve of large industry but apply to any company in the more energy intensive operations such as those in the chemicals and paper sector. An ESOS audit will recommend cost-
effective measures with the objective of saving energy and money. With the continuing rise of energy costs which make up a large part of operational expenses, efficiencies will help to maintain and increase competitiveness and have a positive impact on greenhouse gas emissions. For UK plc, cutting unnecessary energy waste is essential to reduce the strain on creaking energy infrastructure. Initial figures suggest that the net benefit of this policy
in the period 2015 to 2030 to the UK will be around £1.9 billion. This is based on a conservative calculation that only 6% of potential energy savings identified will be implemented. It is anticipated that the ESOS programme will identify energy cost savings of more than £31 billion. If only 6% of recommendations result in behaviour changes, can the scheme be considered successful and should it be a precursor for penalties for those that fail to instigate energy efficiency measures? Evidence from The Carbon Trust suggests that three out of every five cost-effective, technically-viable energy efficiency recommendations are not implemented. On this basis it’s fair to assume that while some organisations are putting in place excellent energy efficiency initiatives, a significant number are not. In 2012 industrial consumption accounted for 17% of total UK final consumption of energy products. Low temperature processes (including heating and distillation in the chemicals sector, baking and separation in food and drink, pressing and drying in paper manufacture and washing, scouring, dyeing and drying in the textiles industry) accounted for 32% of total energy consumption. High temperature processes (including coke ovens, furnaces, kilns and glass tanks) contributed a further 17%. Overall, heat use (space heating, drying/separation, high and low temperature processing) was responsible for 72% of total

energy efficiency audit is a good place to start, ensuring that an organisation has a clear picture of its energy use, highlighting where change is needed and what systems are available to deliver improvements. It should also be used to monitor efficiencies, drive further improvements, provide evidence for financing and show return on investment. An audit alone, however, is not enough so where do you start to look for retrofit energy efficiency solutions? First consider the EU’s Environmental Technologies Verification scheme (Tritech ETV). Funded by the EU's Life Environment Programme, this validates the performance of green-based technologies. It’s a good idea to approach the Carbon Trust as approved systems qualify for financial support under the Energy Efficiency Finance Scheme.
REDUCING ENERGY BILLS BY 25% The Minimise Energy IMOP system (inductive motor optimisation panel) complies with both. Suitable for energy intensive facilities, it works by saving the electricity wasted in the normal running of electrical equipment, reducing energy bills by as much as 25% and increasing the efficiency of motors, extending the life of electrical equipment. Unlike other power correction systems,
the briefcase sized IMOP works on individual units and can be tested to show energy and cost savings before installation. The UK is developing an array of energy efficient industrial solutions – don’t wait for a government scheme to take advantage of them.
