by 25 per cent by 2015, forms part of its ‘Cleaner and Greener’ campaign – an initiative geared towards reducing the council’s overall environmental impact. In line with this campaign, the council identifi ed the Cotswold


Leisure Centre as a facility where several sustainability targets could be met through a reduction in electricity consumption. The council recognised that voltage optimisation – an electrical energy-saving technique in which a device is installed in series with the mains electricity supply, to provide an optimum supply voltage for the site’s equipment – can help lower carbon emissions and reduce energy costs. It therefore asked EMSc (UK) Ltd to complete a site survey to assess whether voltage optimisation could help realise savings at the centre. “On the whole, the National Grid supplies a higher voltage than is generally

The Energy Event is the UK’s leading exhibition and conference for industrial, commercial, public and not-for-profi t users of energy. It targets professionals who are looking to get a grip on their company’s energy use, comply with legislation and put in place sustainable and cost-effective energy effi ciency and procurement solutions. It offers a CPD-certifi ed conference,

spread across four theatres and featuring over 70 speakers, alongside an exhibition showcasing 190 energy management and effi ciency product and service providers.

required,” says EMSc (UK) MD Dr Alex Mardapittas. “Although the nominal voltage in the UK is 230V, the average delivered is actually 242V. This ‘over-voltage’ means that energy consumption is not only higher, but as a result, the lifespan of equipment is shortened.” Voltage optimisation has also been shown to improve power quality by balancing phase voltages and fi ltering harmonics, as well as transients from the electricity supply, leading to reduced maintenance costs as less demand is placed on equipment. It was found that the centre could

realise substantial savings by implementing voltage optimisation technology, and a 286kVA Powerstar unit was installed. This helped reduce the centre’s direct electricity consumption – an overall energy saving of 8 per cent was achieved – while CO2 emissions were reduced by 54 tonnes. The council also achieved an annual saving of £7,800 on electricity costs.

fi nd the best prices, but also to determine any obstacles you may face when it comes to accommodating the deposit requests of the utility companies. Meanwhile, a number of fi nancial

products are currently being developed by suppliers and fi nancial houses to bridge the gap when it comes to paying your energy deposit. Currently proving popular in the US is the use of unsecured loans through merchant banks; if this solution is rolled out in the UK, it will provide fi nance to the trader to pay the deposit for the energy contracts. Utility deposit bonds are also

currently available for larger deposits of between £50,000 and £1m, although these often require extensive security checks, including an insurance policy and a bank guarantee. The advantage of this option is that the customer will benefi t from a cheaper fi nancial tariff on the back of the guarantee provided to the utility company. There are also emerging ways and

means for companies to seek funding support for energy management and technology solutions. In November 2011, for example, the government launched

its Renewable Heat Incentive (RHI), an initiative that provides capital investment for businesses to install renewable heat generation equipment. By essentially footing the bill, the scheme is enabling the installation of technologies such as ground source heat pumps or combined heat and power systems in non-domestic buildings up and down the country. Furthermore, it’s enabling companies to recoup savings to put towards further energy-effi ciency measures. Getting to grips with your energy use can be a daunting prospect, but there is a lot of support out there; it’s simply a case of looking in the right places.
