Looking after the environment has never been more crucial, with companies large and small looking to introduce new, innovative ways of reducing their carbon footprint.
optimisation is an electrical energy saving technique that provides a controlled reduction of the incoming voltage supplied to a building, saving an average of 10 to 15% of total electricity consumption and associated CO2
emissions. This can
equate to a great deal of financial savings. If you’ve never heard of voltage optimisation before – you’re in the minority. Voltage optimisation is fast becoming one of the most popular and efficient energy saving techniques available at a commercial level, and Building and Facilities Managers across the globe are becoming increasingly aware of the need to invest in this crucial technology.
Carbon Reduction Commitment One incentive for companies to improve energy efficiencies is the introduction of the Climate Change Act, which has set legally binding targets to reduce carbon emissions by 34% by 2020 and 80% by 2050, based on 1990 levels. In response to the Act the UK government has introduced a number of schemes to encourage large organisations to reduce their carbon emissions. One such scheme is the Carbon Reduction Commitment, a mandatory emissions reducing programme, which aims to improve energy efficiency and reduce the amount of carbon dioxide emitted in the UK. The original scheme was launched to
encourage large
organisations across the UK to monitor their carbon dioxide
emissions. For every tonne they emit, they would have to surrender an ‘allowance’, which would be bought at the start of the financial year. Allowances could, under the original scheme, be sold-on at a price
determined by the buyer. However, following the
Chancellor’s Spending Review in October 2010, if an organisation doesn’t surrender enough allowances, they will now be taxed for every tonne of carbon dioxide they don’t submit allowances for. It is in the best interest of companies therefore, to lower energy usage, not only to save money on their annual electricity bills, but also to reduce their carbon emissions, to ensure they will not be taxed by central government.
Voltage Optimisation
One quick, cost effective method to lower carbon emissions is the installation of a voltage optimisation system. Voltage

One solution capable of achieving this is EMSc (UK) Ltd’s market leading voltage optimisation system – Powerstar. The system, which is entirely designed and manufactured in the UK, is proven to provide optimum savings and improve the life expectancy of electrical equipment. There are two types of voltage optimisation system available on the market today: simple step-down transformers that drop the voltage only, and voltage optimisers that optimise the voltage as they reduce it. In doing so, true optimisers tackle poor power quality
Building & Facilities Management – April 2011
The reason voltage optimisation can have such a significant impact on energy used, lies in the fact that generally speaking, the National Grid supplies a higher voltage than required to both commercial and residential sites, and although the nominal voltage in the UK is 230V, the average is actually 242V. This ‘over-voltage’ means that energy
consumption is not only higher but that as a result, the lifespan of equipment is shortened. Voltage optimisation systems not only reduce energy consumption but also improve site efficiency.
