The new market is in the form of a Day-Ahead Market (DAM). 4
  6. 6. HIGHLIGHTS and discussions aimed at ensuring that the World Cup is seen as a triumph for the entire African continent. The main achievements for the period under review were as follows: 1. 4. Visit to China Investors Roundtable SADC in conjunction with the SAPP and the Regional Electricity Regulators Association (RERA) hosted the Investors Roundtable in Livingstone, Zambia, from 15-17 July 2009. The aim of the Roundtable was to showcase a collection of SAPP priority projects that could reach financial closure in the next two to three years and to bring together Investors, Financiers, Developers, Project Owners and EPC Contractors and discuss common challenges being faced in the implementation of priority projects in the SADC region. A SAPP delegation comprising of Members of the Executive Committee and some members of the Management Committee visited China from 17-27 November 2008. The SAPP was looking to develop a business relationship with Chinese companies, manufacturers and suppliers of equipment, and to study and understand how China was planning and expanding her power network considering the massive economic development that China was undergoing. 5. 2. Commissioned Generation Projects and end of Power Conservation Program The SAPP received financial support from the Government of Norway and Sida (Sweden) to implement a competitive market in the form of a Day-Ahead Market (DAM). For the most of 2009, market trials were carried out and most Operating Members participated in the market trials. The four issues that prevented the timeous opening of the market were dealt with by the various Sub-Committees and the issues were: During the year up to December 2008, the SAPP commissioned a total of about 1,442MW of generation capacity as follows: South Africa 962 MW Swaziland 20 MW Tanzania 100 MW Zambia 60 MW Zimbabwe 300 MW · Internet access to the DAM Trading Platform housed at the SAPP Coordination Centre (SAPPCC) in Harare, Zimbabwe. The SAPP-CC managed to negotiate for an increased bandwidth and the system is now readily accessible to all Members. The projects in South Africa were mainly return-to-service of existing plants. In Zambia and Zimbabwe it was mostly rehabilitation of the existing power stations. In Swaziland and Tanzania, the commissioned generation was Greenfield. In 2009, the SAPP is planning to commission another 2,207 MW. · Treatment of imbalance energy. A Task Force consisting of members from the Markets and Operating Sub-Committees developed an interim solution that was implemented from 1 April 2009. The interim arrangement is subject to review on a quarterly basis. There was demand reduction in 2008/9 due to the credit crunch around the world that also affected the SAPP. The 2008 peak demand for the total SAPP was 43,267MW and the available capacity was 49,089MW. Taking into consideration the 10.2% reserve margin requirement for the SAPP, the SAPP therefore had a surplus of 969MW as at April 2009. 3. Implementation of a Competitive Market · Market surveillance. The Markets Sub-Committee agreed to an interim arrangement that nominated the SAPP-CC Manager as the responsible party to carry out market surveillance and monitoring. · Signing of market documentation. At a Meeting of the SAPP Executive Committee that was held during the year, all the SAPP Operating Members had agreed to sign the DAM Book of Rules and the Legal Participation documents before end of the year so that the market could go-live. It requires at least three Operating Members to sign the said documents for the market to start. Support to South Africa to host the FIFA 2010 World Cup All power utilities within the SADC region signed the pledge to support South Africa and the 2010 FIFA World CupTM in areas of Generation, Transmission, Customer Contributions and Demand Side Management initiatives. The pledge is the culmination of several months of planning 6. Completion of SAPP Reforms During the year, all SAPP Members signed the revised 5
  7. 7. HIGHLIGHTS 8 Inter-Utility MOU. SNEL of the DRC were the last Member to sign the document in November 2008. In an attempt to use power efficiently and reduce demand on the interconnected SAPP grid, the SAPP embarked on a project to replace incandescent bulbs with energy saving bulbs commonly known as Compact Fluorescent Lamps (CFLs). However, concerns were raised about the presence of mercury in the CFLs, which is a highly toxic heavy metal with severe human health adverse effects. The SAPP therefore developed draft guidelines on the use and disposal of these CFLs in a manner that would not compromise human health. The review of the Agreement Between Operating Members (ABOM) was completed during the year and was signed by all the SAPP Operating Members. The only base document that was still under review is the Operating Guidelines. It is expected that the Revised Operating Guidelines will be signed in 2010. 7. CFLs Disposal Guidelines Completion of the Review of the SAPP Pool Plan Nexant, the consultant appointed by the SAPP with grant funding coming from the World Bank, completed the final report on the review of the SAPP Pool Plan. The SAPP is yet to determine a way forward in the promotion and marketing of the projects identified in the Revised Pool Plan. 6

  9. 9. EXECUTIVE COMMITTEE CHAIRMAN’S REPORT Mr. Rhodnie Paul Sisala ZESCO (Zambia) Executive Committee Chairperson The Southern African Power Pool (SAPP) made tremendous progress in the supply of power to the interconnected grid and also organized an Investors Roundtable aimed at attracting investment into the SADC power sector. 1. Zambia and Zimbabwe they were rehabilitation projects, whereas in Swaziland and Tanzania they were Greenfields. In 2009, the SAPP expects to commission a total of 2,207MW of new generation as shown in Table 2. Because of the generation projects that were commissioned and the reduced demand on the SAPP grid, the SAPP recorded a surplus of 969MW as at April 2009 after taking into consideration reserve margin requirement of 10.2%. Power Supply Challenges 1.1 Peak demand and installed capacity The SAPP demand was 43,267MW and the installed capacity increased slightly to 55,927MW from previously 54,084 MW. The increase in the installed capacity was attributed to the projects that were commissioned in 2008 and in 2009. 2. SAPP Visit to China A SAPP delegation comprising of the Executive Committee and some members of the Management Committee visited China from 17-27 November 2008. The objectives of the visit were: § develop a business relationship with Chinese To companies, manufacturers and suppliers of equipment. § To study and understand how China was planning and expanding her power network considering the massive economic development that China was undergoing. § To explain the investment opportunities that exist in the SADC region to China and to work together with China to achieve the SADC regional objectives. The SAPP visit to China covered the visit to the ThreeGorges, State Grid Corporation of China DC-Engineering Construction Company, HVDC Projects and HVDC Technology, Transformer Manufacturing Company and Research Institutes.

As a follow up to the SAPP visit, SGCC has been invited to visit SAPP in 2009. backed by commercial agreements to be negotiated and signed separately between SAPP members and Eskom and include initiatives that will ensure a targeted amount of power supplied, to be green power. Some key parts of the agreement include ensuring adequate transmission capacity for the transfer of power to South Africa, preventative pre-event maintenance and clean servitudes, maximizing plant production, energy efficiency initiatives and load management during the events. SAPP members will also engage in demand-side initiatives and manufacturers will be encouraged to slow production during the evening peak and optimize production during the off peak periods. Some may also elect to take their plants off the grid for planned maintenance during game times, thus reducing pressure on the interconnected SAPP system. SAPP officials pose for a photo in China The surplus power intervention would ensure that any surplus power capacity that SAPP members may have would be made available to Eskom as a contribution towards the 2009 and 2010 events. 4. Investors Roundtable SADC in conjunction with the SAPP and the Regional Electricity Regulators Association (RERA) hosted the Investors Roundtable in Livingstone, Zambia, from 15-17 July 2009. The aim of the Roundtable was to showcase a collection of SAPP priority projects that could reach financial closure in the next two to three years and to bring together Investors, Financiers, Developers, Project Owners and EPC Contractors and discuss common challenges being faced in the implementation of priority projects in the SADC region.

SAPP Pledge to support South Africa's host for the FIFA 2010 World Cup The main recommendations arising from the Roundtable were as follows: At a meeting of the SADC Energy Senior Government Officials and the SAPP Executive Committee meetings that took place in Maputo, Mozambique, on 27 April 2009, the SAPP signed the pledge to support South Africa and the 2010 FIFA World CupTM in areas of Generation, Transmission, Customer Contributions and Demand Side Management initiatives. The pledge is the culmination of several months of planning and discussions aimed at ensuring that the World Cup is seen as a triumph for the entire African continent. 2.1 Project Development A Project Implementation Team be set up for Interconnectors, a National level Project Development Framework be established in each country and a Project Acceleration Unit be set up at regional level. 2.2 Revolving Risk Capital Bridging Facility A facility should be set up and administered by a regional DFI (such as the Development Bank of Southern Africa, DBSA) to provide risk capital funding for the “pilot” list of projects to overcome the equity problem faced by power utilities. These funds would be refinanced, e.g. at COD, The initiative is part of Eskom's plans to ensure the reliability of electricity supply for the 2009 Confederations CupTM and the 2010 FIFA World CupTM. The pledge of solidarity among the Southern African countries will be 9

EXECUTIVE COMMITTEE CHAIRMAN’S REPORT and applied to the next ready project. 2.3 Regional Regulation Regional regulatory environments move towards being more compatible, drawing on lessons learnt from the structure within ECOWAS. Standardization of power purchase agreements (PPA) terms where possible was encouraged, thereby leaving negotiations to focus only on project specific elements. 2.4 Enhanced Buyer Model The current single buyer model be enhanced to allow intensive energy users to underwrite power projects directly, thereby relieving Utilities of the burden of having all regional projects coming to them for a PPA. The SAPP Executive Committee is reviewing the recommendations which if accepted, a way forward would be developed. The SAPP, working in conjunction with DBSA, SADC Secretariat and RERA have agreed to a close-out meeting to be held before end of year 2009 in order to develop a roadmap on the implementation of the recommendations, where applicable. 5. Acknowledgement I would like to take this opportunity and thank the members of the SAPP Executive Committee for the support that I received as Chairperson of the SAPP Executive Committee during my tenure of office. I would also like to thank Mr Manuel Cuambe, the previous Chairperson who worked tirelessly hard to make the projects implemented within the SAPP. Mr. Rhodnie P.

  13. 13. MANAGEMENT COMMITTEE REPORT Mr. Christopher Nthala ZESCO (Zambia) Management Committee Chairperson 1. Introduction documents, applications for new membership of SAPP were received from Copperbelt Energy Cooperation (CEC) of Zambia, Mozambique Transmission Company (MOTRACO) and WESTCOR of Botswana. These applications were under the consideration of the Management Committee. Mr Christopher Nthala, ZESCO Generation and Transmission Director, was elected Chairperson of the SAPP Management Committee from September 2008. Under the leadership of ZESCO, the SAPP Management Committee carried out the following activities in the year under review: i. Completed the review of the Inter-Utility MOU and the Agreement between Operating Members (ABOM) and made all Operating Members sign the revised documents. ii. Undertook the SAPP Tariff Study to determine the underlying principles that surround electricity pricing and tariff setting in Southern Africa. iii. Spearheaded the implementation of demand side management (DSM) initiatives in the region, and iv. Instructed the development and implementation of a solution to handle imbalance energy in the power pool. 2. The CEO of SNEL (DRC) signing the Revised Inter-Utility MOU in Kinshasa in November 2008 3. SAPP Tariff Study The Final Report on the SAPP Tariff Study was completed and issued in July 2008 with recommendations on best tariff setting principles and practices. The recommendations were presented to the Ministers responsible for energy in the SADC region in April 2009. The key recommendations from the study were as follows: SAPP Reform and Documentation Review All Members of the SAPP signed the Revised Inter-Utility Memorandum of Understanding (IUMOU) by the end of November 2008. SNEL of the DRC was the last Member to sign the Revised IUMOU. The Revised IUMOU now permits other Electricity Supply Enterprises to join the SAPP and become Members. i. ii. The ABOM was also reviewed and finalised. The revised ABOM has been signed by all the SAPP Operating Members. The only base outstanding document to be reviewed is the SAPP Operating Guidelines. Following the SAPP reform and review of the base 12 The SAPP and the Regional Electricity Regulators Association (RERA) should establish a set of general tariff guidelines, focused on transparency and unbundling in price setting, especially as regards network tariffs. The SAPP and RERA should attempt to ascertain the likely role for marginal cost concepts in tariff determination over the next few years.
  14. 14. MANAGEMENT COMMITTEE REPORT iii. Figure1. With an exception of the HWLC units, the other technologies are aimed at hardwiring the energy savings into the grid. The SAPP should determine what types of internal network pricing models are compatible with increased trade and improved network service quality. iv. The SAPP should adopt the harmonization of accounting methods and techniques and move towards unification. v. SAPP Members should continue to use cost plus methodology and cap approaches to network costs and consider moving towards marginal cost analysis and pricing until systems are fully built out. vi. Subsidies should be funded directly by governments, and vii. As is depicted in Figure-1, the SAPP is expected to save a total of 1,000MW in 2009 using only CFL technology. In 2010, commercial lighting technology will be employed and the savings are expected to reach 1,600MW. By 2011 and with the implementation of the whole selected technologies, the savings will be as much as 3,000MW. SAPP is now working on a Business Case for Commercial lighting. The SADC governments should consider establishing regulators in their own countries to be responsible for electricity regulation and to ensure transparency in price setting across the region. Regulators should approach tariff adjustments with the aim of ensuring that the service is sustainable and there are sufficient incentives for system expansion. Fig 1: Load Management Strategies 5. viii. The SADC governments and regulators should consider, whenever appropriate, the move to multiyear price determinations in the region so that utilities and customers can see price certainty supportive of the massive investment programmes that are needed to address the diminishing generation surplus capacity. The SAPP Management Committee recommended the acceleration of the settlement of imbalance energy among members. The Committee further mandated the Operating and Markets Sub-Committees (the Task Force) to develop a technical solution in the handling of imbalance energy. The Task Force has come up with an agreement and a way forward on the treatment of imbalance energy in the SAPP from 1 April 2009 onwards. The agreement is an interim solution and would be reviewed before end of year 2009 after a scientific methodology has been concluded by the Task Force. The Task Force would be led by the SAPP Coordination Centre. At a meeting of the Ministers responsible for energy in the SADC region, individual utilities and governments agreed on how best to implement the recommendations. The SAPP Tariff Study was funded by a grant from the Development Bank of Southern Africa (DBSA). 4. Imbalance Energy Management Demand Side Management Initiatives 6. The concept of the Demand Side Management Power Station (DSMPS) is the roll out at the regional level of energy efficiency technologies that will reduce the demand increase. As part of the DSMPS, compact fluorescent lamps (CFLs) were identified as the first technology to be commissioned. Cooperation with Partners 6.1 Norwegian and Sida support The SAPP Project Document covering the period from January 2009 to December 2011 was developed by the SAPP and was accepted by the Government of Norway and Sida (Sweden). The Project Document is the guiding document in the implementation of a competitive electricity market. The government of Norway and Sida has availed a grant of around NOK 32 million for the project. Compared to incandescent bulbs, CFLs can save up to 80 % of electricity. Initially, the first four technologies will be made up of CFL's, Commercial Lighting (retrofits), Solar Water Heating and Hot Water Load Control (HWLC), see 13
  15. 15. MANAGEMENT COMMITTEE REPORT 6.1 ACP-EU Energy Facility 8. The priority actions financed from the ACP-EU Energy Facility for the SAPP (EUR 0.7 million) are mainly capacity building for network operations, system planning and promotion of public-private partnerships. I would like to take this opportunity and thank my predecessor, Mr. Nathaniel Maphathe of LEC, who chaired the SAPP Management Committee from September 2006 to September 2008. His contribution and leadership provided to the SAPP during his tenure of office is highly appreciated. 7. Power Pool Coordination Acknowledgement I would also like to thank Members of the Management Committee for the confidence that was shown in ZESCO by nominating ZESCO to Chair the Management Committee. The Coordination Centre Manager, Dr Lawrence Musaba, and the SAPP Chief Engineer, Mr Alison Chikova, attended the West African Power Pool (WAPP) General Assembly and the Donors meeting in Cotonou, Benin, from 29-31 October 2008. The SAPP and WAPP signed a Memorandum of Understanding (MOU) to enable the sharing and exchange of information between the two power pools. Dr. Musaba signed on behalf of the SAPP and Engr. Babatunde Adeyemo, Director, Information and Coordination Centre, signed on behalf of WAPP. Mr. Christopher Nthala Management Committee Chairperson Dr. Musaba (SAPP) and Engr. Adeyemo (WAPP) displaying the signed SAPP-WAPP MOU 14
  16. 16. OPERATING SUB-COMMITTEE REPORT April 2009 Onwards The OSC and Markets Sub-Committee (MSC) met jointly. It was agreed that Control Areas should be submitting interchange energy data to the Coordination Centre for monitoring and analysis. A tolerance band was agreed upon within which Inadvertent Energy would be paid back in kind by Control Areas. Other categories of interchange energy imbalance would be settled financially by Control Areas. The OSC and MSC agreed to meet jointly and come up with a suitable methodology for categorising and pricing other interchange imbalance energy. Interchange of emergency energy support shall be done in accordance with the SAPP governing documents. Mr. Leandro Kapolo NamPower (Namibia) Operating Sub-Committee Chairperson 1. System Demand Situation 3. Last year, because of rising demand and insufficient generation, most SAPP utilities declared system emergencies. In all SAPP utilities various load-shedding programmes were implemented. Eskom (South Africa) devised a recovery programme that was endorsed by SAPP members. As part of the recovery programme, Eskom cut power exports by ten percent (10%) and requested all South African customers to reduce load by the same percentage. The 2008 peak demand in the SAPP interconnected system was 43,267MW and that for Eskom was 35,959MW. Compared to the year 2007, the SAPP interconnected system demand and the Eskom system demand were less by about 2,466MW and about 554MW, respectively. This was largely attributed to the various load reduction activities implemented by SAPP utilities and the global economic down-turn. 2. Status of System Interconnection 3.1 Restoration of Interconnection The interconnected system disturbances which occurred between 19 and 21 January 2008 and between 2 and 3 February 2008 resulted in the SAPP operating as three (3) separate islands: § Zambia-DR Congo (ZESCO & SNEL), § Zimbabwe-Mozambique (ZESA, BPC-North & EDM-North/HCB), and § Africa – Botswana – Mozambique – Lesotho South – Swaziland - Namibia (Eskom, BPC-South, EDMSouth, LEC, SEC, NamPower) Interchange Imbalance Energy The ZESA-BPC-Eskom (Zimbabwe-Botswana-South Africa) interconnector was returned to service on 3 April 2008. 2.1 Accumulation from January2008 The Operating Sub-Committee (OSC) noted that from January 2008 to March 2009 there was a huge accumulation of interchange imbalance energy. Several meetings were conducted to address this accumulation. Eventually the interchange energy imbalance was categorised as Inadvertent Energy, Emergency Energy and Other Imbalance Energy. This was summarised and allocated to supplier and consumer among the Control Areas. It was resolved that pay-back and financial settlement of this accumulation be agreed and done bilaterally by respective Control Areas. A Joint Technical Committee (JTC) comprising experts from ZESA and ZESCO (Zimbabwe and Zambia) was constituted to find and propose ways of restoring the ZESA – ZESCO interconnection. The interconnection was then returned to service on 2 July 2008. From this day up to 8 September 2008 the interconnection was largely floating as very little trading took place. On 8 September 2008, the interconnection was taken out of service following system disturbances that occurred on 6 September 2008. The JTC made investigations and lined up short-term and long-term conditions for the interconnection to be restored. After minimum conditions for restoration were met, the interconnection was returned to service on 14 November 2008. Thereafter active energy trading resumed via the interconnection. 3.2 Zambia-DR Congo Interconnection 2.2 Handling of Interchange Imbalance Energy from 1 15
  17. 17. OPERATING SUB-COMMITTEE REPORT works, among other activities: The Zambia – DR Congo (ZESCO – SNEL) interconnector (220kV Luano – Karavia line) was taken out of service on 1 February 2009 for construction works of the T-off substation at Michelo in Zambia. Slightly delayed by bad weather, the system was restored at 17h31 on 7 February 2009. After commissioning of the Michelo Substation, effectively the Zambia – DR Congo interconnector is now the 220kV Michelo – Karavia line. 4. § out comprehensive system stability studies in Carry relation to the system disturbances being investigated. § Review of the operation of the interconnected system considering protection schemes, control devices, load-shedding schemes. System Disturbances § technical capacity for the SAPP in system Build analysis. 4.1 Reported System Disturbances This project is in progress and is expected to be completed by March 2010. A total of twenty-two (22) system disturbances were reported on the SAPP interconnected system in the period from April 2008 to March 2009. Refer to Figure 1 below for general outlook of SAPP system disturbances. Details of the disturbances that occurred have been captured in Table 1 at the end of this report. 5 Technical and other issues 5.1 Telecommunications The SAPP Telecommunications Working Group (TWG) met in Gaborone, Botswana, from 4 to 5 December 2008. The TWG deliberated on the current challenges in telecommunications in the SAPP. The TWG recommended that fibre optic cable(s) be the backbone of telecommunications facilities in the SAPP for adequate bandwidth, quality service and cost-effectiveness. The TWG also recommended that, while fibre optic facilities are being installed on remaining gaps on the interconnected system, the existing VSAT telecommunications contract be extended for the next two (2) years. The OSC further received the following recommendations from the TWG: § Operating Members should build fibre optic infrastructure up to border points with neighbouring countries; Figure 1: Reported SAPP system disturbances 4.2 System Disturbance Investigation The OSC constituted a task team composed of members from all operating utilities including Copperbelt Energy Corporation (CEC) of Zambia and Hidroelectrica de Cahora Bassa (HCB) of Mozambique to investigate the system disturbances that occurred since the beginning of the year 2008. These disturbances had various impacts on the interconnected system such as islanding, total network blackouts and interruption of energy trading. Also, in some cases interconnectors were taken out of service to allow stabilisation of individual networks. § SAPP should prioritise the connection of the The three Control Areas with fibre optic to replace the current VSAT system; § All new transmission projects should include fibre optic; and, § Operating Members should work to get a fibre optic connection to the host Control Area. The task team resolved that investigation of some system disturbances cannot be concluded unless a comprehensive study of the SAPP system is conducted. Using funds donated by international cooperating partners, the SAPP employed Norconsult to be the technical team leader of the task team who will carry out the following Implementation of these will facilitate safe and reliable operations of the interconnected system. The OSC escalated these recommendations to utilities through reports to the SAPP Management Committee. 16
  18. 18. OPERATING SUB-COMMITTEE REPORT Republic of South Africa, in August 2009. The workshop was attended by representatives from all SAPP members including MOTRACO, HCB and CEC except for TANESCO and SEC. The second and last part of the workshop was scheduled for November 2009 and all SAPP members confirmed their participation. 5.5 Controllers'/Operators' and Traders Forum The 5th SAPP Controllers'/Operators' and Traders' Forum took place in Mbabane, Swaziland in October 2008. The forum discussed various system operations and energy trading issues affecting the SAPP interconnected system. Dr. Graeme Chown, of Power Planning Associates Energy (PPA), gave a training presentation on interconnected system operation. The forum made recommendations to OSC on the following issues: Figure 2: Some members of the TWG at a recent meeting. 5.2 SAPP SCADA system The SAPP is planning to install the Supervisory Control and Data Acquisition (SCADA) system at the SAPP Coordination Centre in Harare, Zimbabwe. This project will be implemented using funds donated to SAPP by international cooperating partners. Tenders for supply of the system were floated internationally. Bids were received and evaluated. Once contract negotiations have been concluded, installation and commissioning works will commence.

Table 1: System Disturbances from 1 April 2008 to 31 March 2009 No Date Country Detail of Disturbance 1 25 April 2008 DR Congo (SNEL) The Nseke-Kolwezi 220kV line tripped on phase to ground fault following vandalism of the line. This led to the 100MVA 220/120kV transformer at Nseke tripping on overload. Power exports to SAPP were curtailed. 2 6 May 2008 Zimbabwe (ZESA) At 13h52 the 330kV Warren–Dema feeder tripped and locked out due to a yellow-phase transient fault which subsequently led to the trip of the 330kV Mozambique (Songo) – Zimbabwe (Bindura) interconnector on over frequency. Zimbabwe lost 200MW of power imports from Mozambique and its system was split into two islands, the eastern one was blacked out. The western island remained connected to Kariba South and Hwange power stations and to the South Africa (Eskom) interconnection. At 14h06 supplies from Mozambique were established and at 15h10 the two islands were synchronised at Dema Substation (Zimbabwe). 3 7 May 2008 Zimbabwe (ZESA) At 02h17 the 400kV Insukamini – Phokoje line tripped on three phase main protection. This resulted in Hwange Generator 3 and the 220kV Bulawayo- Francistown line tripping. At the same time a bus coupler breaker tripped at Songo (Mozambique) and imports from Mozambique were momentarily observed dropping significantly to 16MW compared to a schedule of 400MW but immediately normalised. Synchronising at Insukamini (03h01) was delayed by the abnormally high voltages on the ZESA system. 4 18 June 2008 Zimbabwe (ZESA) At 13h32 the 330kV Warren busbar was cleared. All the three 330kV lines from Kariba South to Alaska tripped and, subsequently, all generators at Kariba South and the Harare Power Station generator tripped. The ZESA system was split into two islands. Imports from Mozambique supplied the eastern island while Hwange Power Station and imports from South Africa (Eskom) supplied the western one. At Kariba South supplies were established at 14h43. The two islands were synchronised at 16h19. By 17h19 all generators at Kariba South were on line. 5 11 July 2008 Zambia (ZESCO) At 16h33 the 330/17.5 kV main transformer T1 tripped at Kafue Gorge Power Station resulting in the tripping of the associated generators 1 and 2 on over frequency due to loss of load. The tripping of the 330/17.5 kV main transformer T1 was caused by the tripping on Buchholz of the associated single phase transformer T1Y. The ZESCO (Zambia) – ZESA (Zimbabwe) tie line power flow changed from 121MW export to 134 MW import. The system frequency was almost stable with minimal variation. While investigations on the 330/17.5 kV main single phase transformer T1Y commenced, Kafue Gorge Units 1 and 2 were taken out for the rehabilitation works under the planned Power Rehabilitation Project (PRP). 18
  20. 20. OPERATING SUB-COMMITTEE REPORT Table 1: System Disturbances from 1 April 2008 to 31 March 2009 No Date Country Detail of Disturbance 6 10 August 2008 Democratic Republic of Congo (DRC) SNEL At 17h43 Synchronous condenser machine 01 at SCK Kolwezi Conveter Station tripped. At that time, there was over-frequency and over-voltage (from 230kV to 250kV) due to loss of load in the interconnected system and auxiliary supplies were disturbed at Kolwezi. Exports from DRC (SNEL) to Zambia (ZESCO) increased from 20MW to 90MW Zimbabwe (ZESA) At 17h43 the following tripped in the ZESA system: 330kV Sherwood – Hwange 2 line (over-voltage), Kariba South Generator 5 (over-frequency); Hwange generator 2 (overall protection); 330kV Hwange – Insukamini line (over-voltage), 330kV Insukamini – Bulawayo line (Distance main protection ABC), 220kV Bulawayo – Francistown line (over-voltage),Bulawayo 330/220kV transformer T3AB (OCEF), and Hwange Generator 6. The SAPP interconnection was split at Insukamini. A total of 369MW of generation was lost. Power exports and wheeling were disturbed. Zambia (ZESCO) At 17h43 one Kariba North Bank Power Station unit tripped on over-frequency. Also both 220kV Victoria Falls - Muzuma and 220kV Victoria Falls – Sesheke lines tripped, there-by islanding the Victoria Falls Power Station which subsequently tripped because it could not support all the loads in that region. A total of 238MW generation and an estimated 300MW load were lost. 7 19 August 2008 Zimbabwe (ZESA) At 07h12 the following tripped in the ZESA system: 330kV Sherwood – Hwange 2 line (main trip, voltage monitor), Hwange generator 3 (overall protection); 330kV Hwange – Insukamini line, 330kV Insukamini – Bulawayo line (general trip, OCEF), 220kV Bulawayo – Francistown line (over-voltage),Bulawayo 330/220kV transformer T3AB (OCEF), and Hwange Generator 5 (backup protection). A total of about 262MW of generation was lost. Power exports and wheeling were disturbed. 8 6 September 2008 Zimbabwe (ZESA) At 11h56 in the ZESA Control Area, while the 330kV Sherwood Hwange no. 1 line was out for voltage control, the following 330kV transmission lines tripped: Sherwood Hwange no. 2, Hwange Insukamini, and Insukamini Bulawayo. The interconnected system was split at Insukamini. Subsequently, Generator no. 2 and no. 5 at Hwange Power Station and Generator no. 5 at Kariba South Power Station tripped. Hwange Power Station and Bulk Supply Point completely lost supplies and a load of about 48MW was lost. Generation totalling 369MW from Kariba and Hwange was lost while a load of 727MW was out due to planned load-shedding. At Bulawayo, the 330/220kV transformer T3AB and the 220kV Bulawayo Francistown line tripped. Wheeling of 55MW from HCB to BPC, 20MW from EDM to BPC and 68MW from HCB to Eskom, and export of power from ZESA to NamPower was interrupted. Zambia (ZESCO) At 11h56 an incident of high frequency was observed. Immediately at Kariba North Bank Power Station unit no. 1 generating 167MW tripped on over-frequency. Also, tie line flows surged up momentarily from the ZESA into the ZESCO system. Then the ZESA – ZESCO tie line flows dropped to zero (0MW). A situation of under-frequency prevailed in the ZESCO system, leading to tripping several circuits on under-frequency protection. Also, high system voltages were experienced. At 12h33 Kariba North Bank Power Station unit no. 2 generating 174MW tripped on over-voltage. 220kV Victoria Falls – Muzuma transmission line tripped and generation of about 17MW was lost at Victoria Falls Power Station. The ZESCO – SNEL interconnection was lost when the 220kV Luano – Karavia transmission line tripped. Over 520MW of national load was lost in Zambia. 9 10 September 2008 Zimbabwe (ZESA) At 12h31 330kV Sherwood-Chertsey, Insukamini-Hwange and Bindura Songo Lines tripped simultaneously followed by Unit 5 at Kariba South and the only unit in service Hwange, Unit 3.This split the system into three (3) islands. No load was lost. Restoration efforts were immediately engaged but were hampered by serious high voltage and frequency mismatch problems. However, the Songo Bindura interconnector was synchronised at 12h58 the Eskom system was coupled at 13h11. 11 17 November 2008 Zambia / DR Congo The Luano (Zambia) – Karavia (DR Congo) interconnector tripped during lightning thunderstorms on line distance impedance protection. 12 21 November 2008 Zambia / DR Congo The Luano (Zambia) – Karavia (DR Congo) interconnector tripped during lightning thunderstorms on line distance impedance protection. 13 6 December 2008 Zambia At 11h20 generators 1, 2, 3 and 4 at Kariba North Bank Power Station, generating about 650MW, tripped due to loss of 380V auxiliary supplies. Scheduled energy interchange on the ZESA-ZESCO tie line was temporarily affected. 14 13 December 2008 South Africa / Swaziland / Mozambique At 14h23 the Arnot 400kV bus zone protection operated resulting in the loss of 400kV Arnot - Maputo line. At 15h07, while the fault finding was in progress, 275kV Komatipoort - Infulene line tripped due to a line fault. Edwaleni 2 was thus supplied from Camden and consequently low voltages were experienced at Maputo. To improve voltages Mozal was temporarily shed off. 15 19 December 2008 Zimbabwe / Mozambique At 15h32 the ZESA system split into two islands after 330kV Sherwood-Alaska and Sherwood-Norton lines tripped. At the same time the bus coupler circuit breaker tripped at Songo and load on Songo-Bindura line temporarily increased from 256MW to 353MW. About ten minutes later the islands were synchronised and shortly afterwards at 15h43 the bus coupler at Songo was re-closed. 16 24 December 2008 DR Congo At 08h56 Kolwezi 220kV bus zone protection operated leading to loss of 220kV Kolwezi – Panda and Kolwezi – Fungurume lines and trip of Converter no. 21 with a load of 75MW. All this equipment was restored by 13h00 on the same day. 19
  21. 21. OPERATING SUB-COMMITTEE REPORT Table 1: System Disturbances from 1 April 2008 to 31 March 2009 No Date Country Detail of Disturbance 17 29 December 2008 Mozambique At 13h46 the Maputo 275kV bus zone protection operated due to failure of transformer surge arrestor. The following tripped at Maputo: 400/275kV Transformer 01, 275kV Capacitors 03&04, 275kV Maputo-Matola and Maputo-Infuleni lines. At this time the Komatipoort Infulene line was out of service due to a trip-and-lockout of the previous evening. This resulted in power interruption to the Southern EDM network. 18 10 January 2009 Zimbabwe / Botswana At 11h59 Insukamini - Phokoje line tripped and locked out due to Red & Yellow phases transient ground faults as a result of lightning. The loss of the interconnector resulted in interruption of ZESA exports of 146MW to NamPower. The line was restored to service at 12h15 and exports resumed. 19 1 February 2009 Zimbabwe / Zambia At 11h16 the following 330kV lines tripped in the ZESA system:Tokwe-Chertsey,ChertseyBulawayo,Chertsey-Sherwood,Bulawayo-Insukamini, Sherwood-Hwange2 on main protection. The Kariba South G5 tripped on over-frequency, import from HCB dropped, system split. At 11h17, in the ZESCO system 180MW generator G3 at Kariba North tripped and two generators at Victoria Falls tripped on overfrequency due to loss of load. 20 10 February 2009 Zimbabwe At 21h56 the following tripped in the ZESA system: Bulawayo transformer T3AB (differential protection), Chertsy – Sherwood line (main protection), and Kariba South G5 (overfrequency). The system split and load was lost. A surge divertor was found faulty on Bulawayo transformer T3AB. 21 26 March 2009 Zimbabwe / Mozambique At 16h28 the ZESA system experienced a disturbance characterized by trips of the following 330kV feeders: Sherwood- Chertsey and Harven - Bulawayo. This resulted in a ZESA system split and loss of some load and loss of generator number 5 at Kariba South on over-frequency. Dynamic unscheduled change in interconnector power flows was also experienced. This disturbance was attributed to power swings caused by trip of a generator on the HVDC Bus Bar and the Bus Coupler at Songo and suspected load rejection by Songo generators. The split system in ZESA was synchronised eleven minutes later at 16h39. 22 30 March 2009 Zimbabwe At 05h50 the ZESA system experienced a disturbance caused by trip of the 330kV Dema-Warren Feeder on main protection trip. This resulted in a system split and dynamic unscheduled increase in HCB interconnector power flow from 130MW to 249MW. ZESA manually shed off 180MW in the eastern island in order to control the inadvertant energy supplied by HCB. The system was synchronised at 06h55. The delay to sysnchronise was due to failure to reset trip relays from supervisory. This disturbance was attributed to suspected line insulation breakdown during the wet meteorological conditions. 20

Availability of telecommunication facilities is vital in this regard. Following concerns raised by ZESA of Zimbabwe on the impact of frequency relaxation on AGC controls on tie line flows, there is need to assess the extent of this impact and recommend a way forward. 4. Acknowledgement I would like to take this opportunity and thank members of staff of the SAPP Coordination Centre for their hard work during the year that has gone by. Ms. Edeline Mujongondi Temporary Secretary 3. Control Areas surveys Control Area surveys were conducted by the SAPP CC Dr. Lawrence Musaba during the year. A draft report was circulated to all SAPP Coordination Centre Manager members and would be finalized after receipt of comments from members. The preliminary findings were as follows: i. The control equipment was performing well and the telemetering errors were minimal. Also, the frequency bias settings of the Control Areas and interchange scheduling were proper. ii. Overall, generation under AGC was adequate although the SAPP need to do a detailed audit on this. iii. Control Areas need to monitor and control their Control Area performance more effectively as an on-going process both during normal conditions and during disturbances. Criteria, parameters, and procedures for doing this should be clearly communicated to system controllers and key parameters like ACE and frequency should be recorded continuously for access by authorized auditing/survey teams. The SAPP should also assess the impact on Control Area performance of 30

  36. 36. AUDIT OPINION REPORT OF THE INDEPENDENT AUDITORS TO THE MEMBERS OF THE SOUTHERN AFRICAN POWER POOL We have audited the financial statements of the Southern African Power Pool as set out in pages 39 to 51 for the year ended 31 March 2009. Executive committees' responsibility for the Financial Statements The executive committee of the power pool is responsible for the preparation and fair presentation of these financial statements in accordance with International Financial Reporting Standards. This responsibility includes: designing, implementing and maintaining internal controls relevant to the preparation and fair presentation of financial statements that are free from material misstatement, whether due to fraud or error, selecting and applying appropriate accounting policies; and making accounting estimates that are reasonable in the circumstances. Auditor's Responsibility Our responsibility is to express an opinion on the financial statements based on our audit. We conducted our audit in accordance with International Standards on Auditing. These standards require that we comply with ethical requirements and plan and perform the audit to obtain reasonable assurance whether the financial statements are free from material misstatement. Basis of Opinion We conducted our audit in accordance with approved International Standards on Auditing. Those standards require that we plan and perform the audit to obtain reasonable assurance that the financial statements are free of material misstatement. An audit involves performing procedures to obtain audit evidence about the amounts and the disclosures in the financial statements. The procedures selected depend on the auditors' judgment, including the assessment of risk of material misstatement of the financial statements, whether due to fraud or error. In making these risk assessments; the auditor considers internal controls relevant to the entity's internal control environment. An audit also involves the evaluation of the appropriateness of accounting policies used and the reasonableness of the accounting estimates made by the executive committee, as well as evaluation of the overall presentation of the financial statements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a reasonable basis for our opinion. Audit opinion In our opinion, the financial statements present fairly, in all material respects, the financial position of the power pool as at 31 March 2009 and of the results of its operations and cash flows for the year then ended in accordance with International Financial Reporting Standards.

  37. 37. AUDIT OPINION SOUTHERN AFRICAN POWER POOL STATEMENT OF ACCOUNTING POLICIES The following principal accounting policies have been consistently applied throughout the period except as follows: CHANGES IN ACCOUNTING POLICIES The accounting policies adopted are consistent with those of the previous financial year except as follows: The Power Pool in order to comply with IFRS and IFRIC interpretations as of 1 January 2009 with regard to the statement on revenue and revenue recognition in respect of recognised grant income utilised, adopted the systematic pattern of deferring income at recognition to the balance sheet and amortising to the income statement when grant funds are utilised. The change in accounting policy has been accounted for retrospectively and the comparative amounts have been appropriately restated. The principal effects of the change and the statements affected are as follows: IAS 1 ''Presentation of Financial Statements' IAS 8 ''Accounting Policies, Changes in Accounting, Estimates and Errors' IAS 16 ''Property, Plant and Equipment' 2009 Increase in Grant Funds Utilised Increase in Equity Adjustment to Accumulated Funds as at 01/04/2008 2008 01.04.2008 1 598 941 4 291 235 2 692 294 2 692 294 Management exercised professional judgment in re-assessing the residual values and useful lives of all items of property, plant and equipment excerpt items of property, plant and equipment purchased through use of grant funds and items of PPE that had exceeded their useful lives as a date of reassessment. Included in the depreciation charge for 2009 is a change in estimate of USD 713 arising from the decision to depreciate property, plant and equipment on reassessed useful lives. This change in estimate will effect a decrease in depreciation and an increase in carrying amounts of these items of PPE in the future periods. Difference (Decrease in Depreciation) New Depreciation Policy Old Depreciation Policy 713 (10 143) 10 856 ACCOUNTING CONVENTION The financial statements are prepared under the historical cost convention. No procedures are adopted to reflect the impact on the financial statements of specific price changes or changes in the general level of prices. CURRENCY The financial statements are expressed in United States dollars. Assets and liabilities are translated to the relevant currencies at the exchange rate ruling on the balance sheet date. Income and expenditure items are translated at the ruling average monthly rates for the period to which they relate. Realised exchange differences are taken to the income statement in the year in which they arise. Surpluses and deficits on translation of foreign currencies to the presentation currency are included in the income statement in the determination of net income. PROPERTY, PLANT AND EQUIPMENT Property, plant and equipment are stated at cost less accumulated depreciation and accumulated impairment losses, if any. Depreciation is calculated pro-rata based on the straight line method to write off the cost of assets to their residual value over their estimated useful lives. Depreciation is charged at the following rates: Computer equipment Office equipment Office furniture and fittings - 33.33% - 20% - 10% An item of property, plant and equipment is derecognised upon disposal or when no future economic benefits are expected from its use or disposal. Any gain or loss arising on derecognition of the asset (calculated as the difference between the net disposal proceeds and the carrying amount of the asset) is included in the income statement in the year the asset is derecognised. 36
  38. 38. AUDIT OPINION Computer Equipment and Software increased due to the retrospective correction of a prior period error with regard to incorrect accounting for expenditure on software and hardware relating to the Day Ahead Market (DAM) which was expended in the developmental phase instead of being capitalised during the period 2006 to 2008. CASH AND CASH EQUIVALENTS Cash and cash equivalents are defined as cash on hand, demand deposits and short term, highly liquid investments with an original maturity of three months or less, net of bank overdrafts and readily convertible into known amounts of cash and subject to insignificant changes in value. TRADE AND OTHER PAYABLES Trade and other payables are stated at cost. TRADE AND OTHER RECEIVABLES Trade and other receivables are stated at their cost less provision for credit losses. INVENTORIES Inventories are valued at the lower of cost and net realisable value. Costs incurred in bringing each product to its present location and condition are accounted for as follows: Cost is established on the First in First out (FIFO) basis in respect of fuel coupons which are sold to employees. Net realisable value is the estimated selling price in the ordinary course of business. SPECIAL FUNDS Funds granted for specific purposes are accounted for separately as Special Funds on the balance sheet. They are maintained in a separate bank account, any interest earned on the unused funds is credited to, and bank charges are debited to the account. PROVISIONS Provisions are recognised when the organisation has a present obligation (legal or constructive) as a result of a past event, it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation and a reliable estimate of the obligation can be made. RETIREMENT BENEFIT COSTS Retirement benefits are provided for the organisation employees through the National Social Security Authority (NSSA) scheme. Employer's contributions to the NSSA scheme are charged to the income statement when due. REVENUE RECOGNITION Fund Income Received Fund Income received is based on a set budget agreed upon by all members of the organisation and contributions made by members are based on set percentages and proportions based on electricity usage. The income is brought to account per issued invoice to each of the member countries. The accounting policies adopted are consistent with those of the previous financial year except as follows: Interest Revenue is recognised as the interest accrues. Donation Income for specific projects is recognised when the respective expenditure has been incurred. Grant Funds Received Donor grants funds are recognised where there is reasonable assurance that the grant will be received and all attached conditions will be complied with. Upon recognition grant funds received are deferred to the balance sheet and amortised when grant funds are utilised to best match revenue and expenditure. 37
  39. 39.
