Voltage at this level is damaging your equipment This is where you ARE UK average supply voltage Historic UK nominal voltage By Optimising this over - voltage, powerperfector will cut energy consumption by 10-20% How does the powerperfector save energy and maintenance costs? Operating electrical equipment at high voltages leads to significantly higher energy consumption. Lighting and motors use more power at higher voltages. kwh per half hour A 230V linear appliance used on a 240V supply will take 4.3% more current and will consume almost 9% more energy (Electrician s Guide BS7671) powerperfector lowers the voltage and dramatically improves the power quality for a whole site more efficiently than any other technology available. All your equipment will run more efficiently and its energy consumption will be lower. Tesco Macclesfield (Over 1000 Tesco installations by end of 2010) Before installation After installation Power Quality Improvements Installing a powerperfector improves power quality on a site dramatically. Optimising voltages reduces the reactance of some electrical equipment, so there is an overall improvement in power factor on the site. Equipment is protected as the powerperfector eliminates transients up to 25,000V, and harmonics are filtered from the mains. By balancing the phase voltages, the powerperfector maximises the efficiency of three-phase equipment. powerperfector reduces kvar and improves Power Factor Equipment runs at lower reactance, so levels of reactive power are reduced, typically by around 20-35% if no PFC is present. Power Factor is brought closer to unity, which may mean Power Factor Charges are not incurred, giving a further financial saving. Improved Power Factor is an indication of increased efficiency. powerperfector reduces harmonic distortion The site is protected from mains-borne harmonics, and vice versa, so disruptions to the operation of sensitive electronic equipment are minimised. The efficiency of any equipment containing magnetic components is improved contributing to energy savings as the heating effect of harmonics is reduced. By preventing harmonics from entering the secondary side of the HV supply transformer, the powerperfector is able to improve the transformer s efficiency and increase its effective capacity. Customers whose utility meter is on the HV side of their transformer will see higher savings as a result. Reduction in 3-phase reactive power at Hilton Dartford Bridge Improvement in Power Factor at Hilton Dartford Bridge 230V 220V European nominal voltage: rarely used in practice Previous European nominal supply voltage: 88% of Europe remains at this level This is where you SHOULD BE! % reduction in average kwh consumption 11.7% reduction in average maximum demand 14.1% reduction in base load comsumption 06/01/ /02/ /03/ /04/ /05/ /07/ /08/ /09/ /10/ /11/ /01/2009 Optimising the supply voltage allows equipment to use only the energy it requires to operate efficiently. For example, providing a motor with its optimum voltage prevents excess heat and vibration, while delivering the required torque and speed. When these effects are aggregated across a whole site the energy saved adds up on average to a 13% reduction in kwh consumed on an 8% Optimisation. The Maximum Demand of the site is also reduced typically by as much as 10% - which will bring a site within its Agreed Service Capacity and reduce penalty charges if it is close to its limit. When the voltage is not Optimised, the pressure on electrical powerperfector improves phase balance Our technology is able to improve phase voltage balancing, without any active components or moving parts. The operation of three-phase equipment particularly induction motors is much more efficient if the phase voltages are closely balanced. For large industrial sites that are heavily dependent upon such loads, improving phase balance can yield energy savings of over 20% in motors. powerperfector protects your assets Our technlogy makes your electrical supply more robust, and improves your site s security. Transients which are very brief spikes in voltage from the grid are eliminated provided they are less than 25,000V. The looming energy gap will further reduce power quality so powerperfector s high level of transient protection is essential to safeguard your electrical and electronic infrastructure. Reduction in total harmonic current distortion at Hilton Dartford Bridge 216V 207V UK Statutory minimum voltage UK (from June 2008) and European statutory minimum voltage components is greater, which shortens their lifespan. A 230V rated lamp used at 240V will achieve only 55% of its rated life. (failing after 550 hours instead of 1000 hours.) (Electrician s Guide BS7671) By Optimising at source, the powerperfector is able to extend the lifetime of all the electrical equipment on a site, substantially reducing maintenance overheads in addition to the energy savings. Inside your powerperfector A finely-balanced interaction of magnetic fields allows the power quality improvements above to be realised, along with Optimisation of the supply voltage, without the need for moving parts or active components. It is a custom designed energy-saving technology not a relabelled older technology so efficiency and reliability are fundamental in its design. By sustaining 99.9% efficiency across its entire operating range, it ensures that the energy saved on downstream equipment is not offset by losses in the unit itself. As a completely passive device, the powerperfector will operate for years without the need for maintenance Fit and Forget. HILTON DARTFORD BRIDGE HOTEL 13.5% SAVINGS - 32,000 per annum

5 Your Four Steps to Energy Saving and Increased Security 90% of Commercial, Industrial and Government buildings will save u p t o 20% on their electricity bills and carbon emissions if they are powerperfected. With your assistance we will take you through our no cost Four Steps from enquiry to business proposal, and then installation, if you decide to powerperfect your building. 1 Please or call us with the following data for as many sites as you like: 1. Your highest hourly maximum demand in kw or kva in the last year for each of the incoming supplies to your building. 2. Your total kwh consumption for the last 12 months on each incoming supply. 3. Your estimated cost per kwh, including CCL, for the next 12 months. We shall you back a provisional cost/value page (below) for you to review before moving onto the next step. If you like the numbers, we will send you a logger to record your voltage profile. The logger will be sent by special delivery with clear instructions and you just plug it into a 3-pin plug point for 7/9 days before returning it to us to analyse. We will send you a graph of your voltage profile (right) with a recommended Optimisation level and an updated cost/value page if your site s voltage differs from the National Average of 242V. 2 4 SURVEY & QUOTATION REPORT 3 When the graph confirms your opportunity we need to survey your site. The financials are still looking good but only show an estimated installation cost, so you need our Engineering Department to arrange for either your preferred contractor, or our approved one, to formally survey your site for a fixed cost quote for the installation. We liaise with you and then submit a final cost/ value page and a full business proposal. You will then be in a position, within just three to four weeks of contacting us, to review the business proposition with your team. If, after receipt of the business proposition, you would like us to give your team a full presentation on our technology to assist in the decision making process we will be delighted to do so. PROPOSAL powerperfector Performance Guarantee: Clients will generally review several of our case studies before committing to buy powerperfector and will see that savings levels can vary - even at the same optimisation level. This is because different equipment will show different savings levels after an installation. With this in mind and for your commercial comfort we guarantee that the overall savings level for your powerperfector project will achieve a minimum of 80% of the predicted Return on Investment (ROI) percentage as You have decided to go ahead so the final step is the Installation Installation is straight forward and our Engineering Team will liaise with you to make sure that, at a time convenient to you, your unit is delivered and the contractor is there to put it in position and start the pre-works. Installation will be arranged at a time that best suits your operational requirement. Pre-shutdown preparation time varies with the size of the unit and will take anything from 1hr upwards but does not interfere with your site s operation. Then, at the time agreed, the contractor will interrupt the supply to the site and install the powerperfector unit as quickly as possible. 30 mins to 5 hours downtime is normal and mobile generation can be provided. We take full responsibility for the work of all our contractors, who are rigorously vetted by our specialist Engineering Team. Unit delivery is between 1 and 12 weeks of your order.

6 The powerperfector Plus - for specialist applications - launched 2008 Proof of Savings The powerperfector Plus is a Voltage Optimisation and stabilisation technology for specialist applications. It does not supercede the powerperfector which remains the best choice for 9 out of 10 sites in the UK. In addition to all powerperfector s benefits the pp Plus features dynamic Voltage Optimisation that ensures a stable voltage output band where sites have high supply volatility and lows at the 220V 225V level. The pp Plus features a thyristor-based control module that allows Optimisation settings to be rapidly adjusted in real time ( 1 th / 1000 of a second), responding to changes in the input voltage. In this way, output voltage is confined to a restricted band, as illustrated below. This switching occurs electronically and without noise, and there are no moving parts. The graph below illustrates a typical input and output profile where a pp Plus is installed with an output setting of 216V.

Our savings analysis for complex sites utilise a fully IPMVP adherent evaluation. The key features are: Analysis is always based on your half-hourly data. The savings from a powerperfector can be seen from your main meter an objective source of data held by your utility provider that forms the basis of your bill. Commit to a methodology in advance. Before we install a powerperfector unit, we will produce a pre-installation report wherever possible, showing how we will determine the savings that the unit delivers. This gives you the absolute confidence that your savings have been measured objectively. Model the energy use where possible. In our pre-installation report, we will build an accurate model of the site s energy use by, for example, reviewing shift patterns, production volumes and temperatures. We only claim real savings from your powerperfector. It is important that we isolate the savings made by the powerperfector from any other of your energy efficiency initiatives and do not claim credit for other changes. We explain the step-by-step methodology in a report. Measurement Standards Our advice; Always challenge your supplier to give you a thorough, objective analysis, and to prove that their conclusions are statistically significant: don t settle for a single chart, a single figure or a magic meter to tell you what you have saved. Important features of the pp Plus: Thyristor switch combinations are selected by the control module and when the input voltage reaches a set percentage deviation from the required nominal output voltage, the thyristor switches bring the voltage back into the pre-set band. The pp Plus can Optimise voltage by variable percentages depending on your requirements The ability to adjust voltage upwards provides protection for equipment against under-voltage particularly important for motor start-ups if you are located in an area of supply volatility. The pp Plus has six minimum output settings that can be adjusted while the unit is in operation from a minimum of 210V to 222V to fine tune your supply. Over 100,000 units have been in operation in Japan over the last 9 years and there have been no recorded failures. The pp Plus is guaranteed for ten years and is available in sizes up to 2MVA. LONDON BOROUGH OF HAVERING TOWN HALL 280KVA pp Plus average 11% SAVINGS Mark Lowers, Energy Management Officer does what it says on the tin Security of Supply: The powerperfector is the only technology available that increases the security of your supply as it has an unblemished record over 15 years and 300,000 units in operation. Critically it does not require maintenance and is guaranteed for 15 years. It operates 24/7 to protect your equipment, save you energy and reduce your carbon emissions. It is our responsibility to make sure you have all the facts before making a decision to install at-source Voltage Optimisation technology, so please consider the following questions: YES NO Has the performance of the technology been independently verified & are independent reports available? Can the supplier present independent proof of improvements in power quality? Is performance measured according to an internationally recognised M&V protocol? Are multiple case studies or testimonials from a variety of sectors openly available? Is the savings guarantee independently backed by a bond? Is the technology recommended by a major utility provider? Is the technology genuinely fit and forget? * If the answer to any of these questions is NO, your site could be at risk. * A fit and forget technology will not have a thermal alarm system that needs constant monitoring in case it overheats.
