1 Business Energy Efficiency Seminar Theatre 21 May 2014 Sponsored by ABB 10:45-11:05 SCARF presentation - Introduction to energy efficiency in business Billy Sloan, Chief Executive 11:05-11:25 ABB presentation - Energy savings utilising power factor correction Mike Thornton, National Power Quality Manager Energy Savings Utilising Power Factor Correction What is power factor? Why is power factor correction important? Typical Installations Savings - PFC solutions that pay for themselves practical examples Overview of the benefits of power factor correction. 11:25-11:45 Recent developments and new applications in Organic Rankine Cycle technology Stéphane Sénéchal, Sales Area Manager, Turboden S.r.l. The Organic Rankine Cycle technology has become the most popular process for improving sustainability and energy efficiency by generating power from medium and low temperature heat sources. This presentation describes recent developments and new applications in ORC technology, from the view point of market-leading Turboden. They have pioneered this technology from the beginnings in the 80s up to today s multimegawatt ORC plants, with more than 220 ORC plants installed worldwide. In February 2013 Turboden started-up its first application in steel industry: a heat recovery system for power generation, supplied to NatSteel plant (Tata Group) in Singapore. The ORC is a 700 kw unit that recovers waste heat from a billet reheating furnace. Furthermore, Turboden supplied a new 3 MW ORC unit, that uses part of the saturated steam produced recovering heat of the exhaust gasses from the EAF (Electric Arc Furnace) at ESF (Elbe-Stahlwerke Feralpi GmbH) in Riesa, Germany. This is the world first EAF waste heat recovery plant with cogeneration based on ORC technology. Additionally, Soon after the acquisition, Turboden has already signed in December 2014 an order with MHI for a new 5 MW geothermal power plant in Japan based on the experience acquired between 2012 and 2013, with two-pressure level 5 MW geothermal power plant for the Munich Public Utilities Company SWM (in Sauerlach), and two other 5.6 MW plants in the same region for the leading company Hochtief Energy Management, now SPIE Group (in Dürrnhaar and Kirchstockach). The background for the investment and the technological choices are explained. Project milestones, commissioning and first operational results will be presented 11:55-12:15 Improving industrial energy efficiency using the Heliex Wet Steam Screw Expander Professor Dan Wright MBC, BSc, CEng, FIMechE, CEO, Heliex Power Heliex Power Limited is a Scottish company making serious progress in developing products in the field of energy efficiency. Heliex is becoming a world leader in steam screw expanders and their applications in the recovery of energy from industrial

2 processes. Major investors in Heliex are BP Alternative Energy International and Novusmodus ESB was a significant year for the and growth of Heliex, who were awarded one to watch recognition in the prestigious GP Bullhound Connect Awards. Heliex were also one of the few UK companies listed in the important 2013 Global Cleantech 100 list. Key learnings: Economically filling in the energy recovery gap between superheated steam turbines and Organic Rankine Cycle systems Electrical power generation by recovery of waste heat from engine exhausts, industrial flues and other processes through the expansion of wet steam. Use of the Heliex screw expander genset to generate electricity by replacing steam pressure reduction valves. Heliex has developed a new strategically important technology for the recovery of energy from industrial processes and exhaust gases. The presentation describes the thermodynamic and mechanical operation of the steam screw expander, provides economic analysis of a variety of applications and industries, and the associated CO2 reductions. Video of units in operation will be included in the presentation. 12:15-12:35 Energy efficiency the contribution of onsite renewables Graham Hygate, Managing Director, Fine Energy Increasingly buildings and businesses are embedding on-site renewable energy generation within their electrical networks and this offers some special opportunities for energy efficiency. Because of the inherent unpredictability of wind and solar, these technologies also offer some special challenges. The opportunity with embedded onsite renewables is to maximise the amount of clean energy used on site, thereby minimising the need for more expensive energy imported via the national grid from power stations. We do this on our wind turbine sites by use of smart switching - exploiting the flexibility in demand from appliances like storage heaters and hot water tanks to make sure that wherever possible they use free, clean energy from the on-site source. The challenge is that demand and supply do not generally match. Take the example of rooftop solar panels. These generate in the daytime whereas most energy is consumed in the winter and at night. Onshore wind energy production is better matched to demand, being greatest in the winter when our heating requirements are greatest, but again the majority of the energy generated is usually exported instead of being used on site. To overcome this challenge requires the use of short-term energy storage. Appropriate storage technology is still developing and I will talk about some of the options available. The convergence of on-site generation, smart switching and energy storage allows us to optimise return on investment in energy efficiency. On-site generation starts to look more like demand reduction, and renewables become just another way of meeting energy efficiency goals. 12:35-12:55 Energy efficient sustainable water Bob Garrow, Director, R S Garrow Water utilities in England consume 5% of all electricity. 90% of the energy used by water utilities is for moving water around. Disruptive technology game changing plant can clean most local raw non salt water to better than UK tap water. Another piece of kit can clean water after it's been used, waste water, to cleaner than the local natural environmental water. Both technologies

3 are well proven and cost effective from small scale. A scenario :- captures and stores natural raw water cleans it at point of use to better than tap water standards uses the water as normal after use near the point of use cleans the waste water to cleaner than local natural environmental water places this cleaner than environmental water back into the natural water environment (near to where it was captured from the environment) nature moves the water on to its next natural or man-made use alternatively re-use or re-cycle the water Possible effects :- built water and waste water infrastructure are not needed storing rain reduces flooding below pre-development natural flooding levels water utilities infrastructure accounts for 40% of road openings which cause potholes in the roads Carbon lowering :- nature is used to bring water to us and to take water away after use rather than energy to operate built infrastructure the carbon load creating built infrastructure is greatly reduced smoother roads reduce fuel consumption when heated waste water is recycled heat also is re-cycled. 12:55-13:15 A Welsh Government view David Bolton, Assistant Director - Melin Energy Business unit, Melin Homes, on behalf of The Welsh Government This presentation will highlight the importance of funding streams and consistency in terms of financing energy efficiency schemes, particularly in relation to domestic retrofit and the Energy Company Obligation the changes proposed by Central Government in the Autumn Statement are having a massive detrimental impact on the business. And he will pose the question Are we seeing a pattern emerging from the UK government of putting plans in place and then changing them at short notice (e.g. Feed In Tariff, ECO, Pasty Tax etc.)? This is affecting businesses and people in a massive way, and also means that energy efficiency targets are slipping further. He will also provide a very brief appetiser to the afternoon s conference session on energy efficiency in Room 18 (16:00-17:30) 13:15-13:30 Renewable Energy effective energy efficiency or embarrassing failure Robert Leak, Renewable Energy Manager, Energy Team (UK) Key learnings: Selecting the right renewable technology to help energy efficiency within a business. Properly assessing a site to ensure a renewable technology can provide an effective financial solution. Having a clear goal in mind when implementing a renewable energy solution. Renewable energy can play an important role within any organisation in helping to reduce energy costs and improve environmental credentials and general energy efficiency. However, the selection and effectiveness of renewable energy systems is always site specific. It s essential when considering renewable energy projects, to ensure they are correctly assessed, specified and installed, to ensure they meet expectations and that

4 they are appropriate to the site, the buildings and the energy requirements of the business. Some of the questions to be addressed include: Can the energy generated be used effectively? Is the technology being considered the most appropriate? All too often, projects are installed without being fully completed or properly registered, leaving a system which does not work (physically or financially) and which can end up being an expensive long term embarrassment, rather than provide a good solution to business energy efficiency. 13:30-13:55 ABB presentation How can KNX help you achieve a more Energy Efficient Building Christian Schiemann, Local Business Unit Manager - Accessories KNX Measures to increase energy efficiency What is KNX? Potential efficiency savings 13:55-14:15 Innovative finance and funding Chris Cook, Director, Nordic Enterprise Trust Energy financing and funding conventionally uses a mix of interest-bearing debt and equity funding and hybrids. But the prepay form of financing - undated credits sold at a discount and returnable in payment for energy supplied - is re-emerging in use in wholesale energy markets at a time when conventional finance capital is no longer available. The retail use of prepay energy financing and funding via energy loans (ie loans denominated in energy which are the outcome the use of the prepay instrument) is capable of revolutionising the financing and funding not just of renewable energy Mega Watts, but far more importantly, of heat infrastructure and energy saving Nega Watts. Chris Cook of Nordic Enterprise Trust will outline an ongoing Scottish neighbourhood heat project as a case study of a Green Deal that could actually work in practice. There are 20,000 more sites throughout the UK with similar attributes. A resilient network of community level gas-fired power generation and heat storage/grids will enable the UK to build upon existing Danish successful energy policies based upon the over-arching principle of 'least carbon fuel cost' rather than 'least cost'. 14:15-14:35 Differing energy vectors Grant Wilson, Chemical & Biological Engineering, University of Sheffield This presentation compares the differing energy vectors in Great Britain's energy system and provides a powerful graphical illustration of the seasonal nature of daily energy demands in the UK. The presentation has evolved over the last 2 years to incorporate data over a greater time period (from Oct 2010) and now includes the categories of electrical energy generation at the transmission level. The graphical representation has been extremely well received (it has been presented by myself and Ian Arbon at several differing events), and provides a greater understanding of the challenge of the energy transition. It also allows for a greater understanding of the growth of transmission connected wind generation since 2010 and how this compares to the demand for gas, electricity and transport fuels. It is clear when one looks at the whole system, and not just the electrical system in isolation, that this is a phenomenal challenge that requires a multitude of changes, the most important being the reduction of overall energy use.

5 15:00-15:15 Saving paper brings energy efficiency and financial savings Keith Bennett While we're looking at being environmentally responsible in supplying energy: here's something that saves trees, saves the rainforest and saves you money (and energy). Corporations process hundreds of thousands of invoices each year. Every 100,000 invoices Costs 1.5M to handle, weighing 2.5 Tonnes, which uses 60 pine trees. Passing an invoice without paper costs one-tenth, saves those trees, removes the carbon footprint of paper-making and mail-handling, and takes seconds instead of days. Now the Green Squares project adds the final tool for Corporate Social Responsibility: It sponsors the protection of one square foot of real Rainforest for every invoice passed electronically. That 100,000 invoices saves one Hectare (the size of a stadium field). The Aberdeen Energy sector processes 20 million paper invoices a year. (that's 500 tons of paper) We could save 12,000 pine trees and maintain 500 acres of rainforest a year by using e-invoices. Not to mention saving 200m. 15:15 Case histories including: SCARF - Billy Sloan, Chief Executive Élan Hair Design NHS Grampian - Graham Mutch Head of Maintenance and Technical Services, NHS Grampian Facilities Directorate Michelin - Mike Donald, Senior Safety and Environment Risk Manager
