  1. QUAD AFRICA ENERGY Innovative Energy and Demand Control Technology EDC System

  2. QUAD AFRICA ENERGY The Quad Africa EDC Philosophy • Electric power has largely replaced oil as the most controversial energy issue of the new millennium and is growing by more than 80 000 MW per year. (Twice the total South African demand) • Souring costs, high interest rates and environmental damage caused by large power plants have wreaked havoc on the once booming industry. • In most countries, electricity prices have risen faster than the general rate of inflation since the mid1990’s. • In this regard electricity generation has been mostly that of coal fired power plants. These are a major cause of air pollution, and are implicated in the predominant environmental issue of the time, namely acid rain and global warming. • Quad Africa accepted the challenge to become a leading innovative technology service provider to promote an ecologically sensitive approach to the usage of electricity.

  3. Innovative Energy and Demand Control Technology EDC System Designed by Quad Africa for the special energy needs and requirements of the South African retail and commercial sector. EDC directly contributes to a cleaner environment

  4. QUAD AFRICA ENERGY Reducing your monthly Electrical Bill There are numerous technical aspects which can contribute to reducing electrical costs. Many of these concepts - for example • Power factor correction • Harmonics and transient energy management • Load balancing etc. can and will contribute to improved energy efficiency but the core of cost reduction is a simple concept ………… You have to reduce your energy usage and demand for electricity

  5. Reducing your monthly Electrical Bill The market is flooded with: Monitoring Programs Staff behaviour and training programs “Cleaning-up” your power……. …..programs and products, but not a single product restricts, in a fully automated manner, the user to operate within a clearly defined energy budget. This is what sets EDC apart from all other energy products.

  6. QUAD AFRICA ENERGY How ? • With the Quad Africa EDC system, business operators can now be in control of the monthly electrical cost • For example – If your monthly electrical bill is R 50 000, the new +30% increase will result in a R 65 000 monthly bill. • The R 15 000 pm increase can only be reduced if you use and demand less electricity. • With the EDC system, the business operator can now choose, according to a practical scale, the monthly cost of the electrical usage and demand.

  7. QUAD AFRICA ENERGY The Practical of How? • A Quad Africa consultant will survey your business operation by • Assessing the 24-month energy and demand profile • Identifying your essential and non-essential loads • Consider your trading cycles and periods • Determine the effect and impact of seasonality The consultant will then present the EDC financial saving options in accordance to the available and realistic practicalenergy saving options. An electrical energy budget is agreed upon which will meet the business requirements, trading and turn-over requirements - but in order to save, certain well defined and agreed upon inconveniences will periodically occur (to save energy you must use less electricity !) The EDC system is then installed and will control the electrical energy and demand usage as per the client’s preference . The client can monitor the EDC performance “real time” on an interactive website.

  12. QUAD AFRICA ENERGY How to reduce electrical usage and demand in a highly competitive business environment ? • Any retail environment operates on excess and redundancy electrical energy elements. • For example (Lighting and Airconditiong in Retail) • Customers seldom complain if lighting levels (lux) drop by 15%. • Few customers can feel the difference between 22°C and 24°C • The energy input required to maintain 22°C in a 5000m² premises will require 25% more electrical energy than at 24.5°C when the outside temperature is 30°C. • Maintaining 1000 lux over a trading floor of 5000m² will require 30% more energy than 800 lux – though the untrained naked eye will not notice the difference. A further waste factor is the related heat of the 1000 lux which will have to be off-set by the airconditioning.

  13. QUAD AFRICA ENERGY How to reduce electrical usage and demand in a highly competitive business environment ? • Any fast food franchise environment operates on excess and redundancy electrical energy elements. • For example (Heating and Refrigeration) • Food preparation by means of energy intensive fryers with oil mediums are programmed to ensure that the product is never under prepared (acceptable safety margins) • The question is – what happens to the excess heat generated by these safety margins ? The Quad Africa EDC reduces waste heat in a very innovative and energy efficient manner. • The same applies to refrigeration. Produce are often refrigerated to and maintained at safety margins far below what is really necessary. • The Quad Africa EDC applies energy conservation cycles or so-called “green cycles” in heating and cooling.

  14. QUAD AFRICA ENERGY What really happens? • Consider the hot plate of a stove • A 1.2 kW hot plate will boil 1 litre of water on the hot plate in a period of approximately 5 minutes (Selector switch on high) • If you switch the hot plate off for 5 seconds and then back to high during the period of 5 minutes, you will see that the time it takes to boil did not change (Theoretically there may be an argument but in practise – not!) • After 4 minutes you will find that the hot plate is at maximum temperature. If you switch it off for 5 seconds – and then back on to high the temperature of the hot plate will not drop in measurable terms. This is simply because the hot plate stores heat which will not dissipate or disappear when the plate is switched off for 5 seconds. • For the sake of simplicity, we call this method of using stored heat (energy) a “green cycle” which means work is done during that time but no electrical energy is used. • The Quad Africa EDC system calculates how many green cycles can be applied without affecting the process or product. Every “green cycle” saves money and contributes to a clean environment.

  15. QUAD AFRICA ENERGY How does the EDC save electricity? • Electrical costs are derived from two components: • kVA (currently the national cost varies from R60 – R80 per kVA) • kW-hr (currently the national cost varies from 22c to 45c per kW-hr) • By reducing your demand from 600 kVA to 400 kVA you will immediately save 200 x R 70 = R 14 000 per month. • By reducing your energy usage from 150 000 kW-hr to 100 000 kW-hr per month you will save 50 000 x R0.25 = R 12 500 per month • It must, however, be practically and realistically possible for your business operation to be able to accept the energy and demand reductions – which can only be determined after the survey and the resulting energy and demand profile.

  16. QUAD AFRICA ENERGY How will my energy budget be determined? • The client and the consultant will formulate and define an energy budget • The client will be aware of the “inconveniences” which may occur in order to adhere to the energy budget • The “inconveniences” will have minimal impact on trading or income-generating operations / activities • The EDC will allocate a predetermined energy budget to each premises • The energy budget is then allocated to 15 minute trading cycles. • If the premises operate within the allocated budget, no inconveniences will occur. • (inconveniences = less airconditioning, less lighting, less staff facilities) • If the premises exceeds the 15-minute energy budget, the premises will enter a “green cycle” – i.e. less energy will be allocated to airconditioning, lighting, staff facilities and back-of-house operations • The “inconveniences” will be in order of priority (8 Levels defined by consultant and conceded to by the client)

  17. QUAD AFRICA ENERGY Green Cycles 24-Hr Electrical Energy Usage No Trading 19h00-21h45 22h00-09h00 45 min no EDC 15 min “Green Cycle”

  18. QUAD AFRICA ENERGY Define “inconveniences” and how will it affect my business operations? • The non-essential electrical loads will be classified in priority levels 1 to 8 • Airconditioning will be level 8 – which means that it will be the first electrical load to be switched off when the demand or energy usage is exceeding the cap or budget • Hot water cylinders will be level 7 • At level 6 staff facilities like urns, kitchens etc. will be disconnected during the “green cycle” • Lighting levels in less critical areas will be reduced during “green cycles” • Priority level 1 will be a percentage (+/- 30%) of the electrical energy supplied to lighting in critical areas • The EDC will always start by reducing electrical energy to level 8 and will sequentially move to higher priority levels in accordance with the electrical budget requirements
