John Thorby, Senior Manager Integrated Demand Management, Eskom


Published on

With the expected Eskom increases over the next five years, retail service stations are facing reduced profitability and some even closure as profits are continually eroded by rising operating costs. Electricity is one of the costs that can be managed and self generated.

This conference aims to examine best practices in energy efficiency and unpack the options and complexities of generating electricity from renewable energy specifically for retail fuel sites.

  • Energy Service Companies (ESCos) who are accredited by Eskom operate by establishing a three-way partnership between themselves, Eskom and the customer, and use their knowledge of DSM technologies and programmes to determine the best way of obtaining results at customer premises. These organisations are experts within targeted vertical markets, capable of identifying opportunities for achieving reductions in electricity consumption, and scoping and executing such projects.   To participate in the funding programme, the ESCo submits a proposal on potential savings (per load factor) which EEDSM reviews on its technical and financial merits, as well as, energy savings potential. Once a contract has been signed, the ESCo is given the go-ahead to implement the project.   20100121 IDM Presentation

  • The Standard Product model comprises pre-approved rebates for energy savings achieved through specified technologies. Through this programme, customers are able to replace most commonly-used inefficient technologies with their energy efficient equivalents. The Standard Product offer was developed to create capacity to implement small and medium-sized projects. Standard Products, referred to as an application specific standard product (ASSP), are available as off-the-shelf components. Such products, approved by Eskom, are replacements for less energy efficient technologies. A product can be a component, sub assembly or a complete “machine”. Technologies include lighting equipment (CFLs instead of incandescent bulbs) control systems (building/process management, occupancy sensors, daylight sensors etc), and programmable process control systems. Energy saving projects may be undertaken by Energy Services Companies (ESCOs) or customers. Issue: Manual business processes and resource intensive processes for relative low savings.

  • What it is: A sustainable Energy Efficiency package based on free, non-free and services to the customer To deliver Load management during peak times  Reducing 2012 winter peak load How will this be achieved? The mass roll-out of standard offer products to obtain sustainable energy savings Simple residential load management devices will form part of the initiative (Short term load control objective incentivised with in-home display )

    4. 4. 4South Africa’s power system is constrained and will be for next few yearsEskom, together with stakeholders, have kept the lights on since 2008Most power stations are in their mid-life and require increased maintenanceStrategy of shifting maintenance outages can no longer be sustained.Significant maintenance is required to address backlogsInitiatives are in place to keep the lights onIntroduction

The national power system is under strain6√• With themaintenance thatneeds to be done,and the availablecapacity, thesystem will remaintight• The identifiedsupply and demandside initiatives willhelp to improve thepicture• Actualmaintenanceschedule will needto be revised basedon the state of thesystem
    7. 7. The future for electricity pricing7
    8. 8. Electricity Pricing• Eskom has been granted an 8% price increase by NERSA for the nextfive years as part of MYPD3 – this is unsustainable and will need to berevisited.• The municipalities tariff increases are not as strictly regulated asEskom’s. NERSA has indicated that they will do more to regulatemunicipal tariffs in future. Municipal tariff hikes are a big risk tobusiness.• Electricity is still fairly cheap in South Africa but will become relativelymore expensive over the years due to:-• Capital costs for new capacity• Escalating coal costs• Environmental pressures and commitments8

    25. 25. Possible Savingsand Future DesignConsiderations
    26. 26. Possible Savings Opportunities• Lighting – the development of LED technologies will create more andmore opportunities for energy saving. There may even be newtechnologies beyond the LED.• Refrigeration and Air Conditioning – there are new energy efficienttechnologies and appliances. Use of solar energy is becoming morepractical.• Pumping – savings are possible but new designs are required.• Hot Water – use solar or heat pumps• Photovoltaics – has potential but requires space. Efficiency is notgreat and the sun doesn’t always shine. Storage is required.26
    27. 27. Future Design Considerations• Use newest energy efficient lighting technologies.• Explore solar assist options for air conditioning and refrigeration.• Focus on energy efficient building design – insulation, natural light etc• Install only the most efficient fuel dispensing equipment.• Own generation will become more of a necessity due to cost andpower quality. Renewables would be an added bonus.• Electric vehicles and other fuel types will have to be taken intoaccount.27
    28. 28. Challenges of EV’s for Retail Outlets• Costs and availability of electrical infrastructure – much strongernetworks will be required to charge electric vehicles quickly• Cost of electricity – municipal supply tariffs – usage during “peak”periods• Customer requirements for “service stations” – longer trips andresidential charging facilities – will existing locations fit the bill?• Electric vehicle battery technologies – interchangeability and rates ofcharge• Generation and storage of electrical energy?
