  5. 5. ABOUT SAPP • The SAPP was created in August 1995 at the SADC • The SAPP established the Short-Term Energy Marsummit held in Kempton Park, South Africa, when ket in April 2001. From January 2004, the SAPP member governments of SADC (excluding Mauristarted the development of a competitive electricity tius) signed an Inter-Governmental Memorandum market for the SADC region. The new market is in of Understanding for the formation of an electricform of a day-ahead market (DAM) and this was ofity power pool in the region under the name of the ficial opened in December 2009. Southern African Power Pool. The ministers responsible for energy in the SADC region signed the Revised Inter-Governmental Memorandum of Understanding on 23rd February 2006. • The SAPP is governed by four agreements: the Inter-Governmental Memorandum of Understanding which enabled the establishment of SAPP; the Inter-Utility Memorandum of Understanding, which established SAPP’s basic management and operating principles; the Agreement Between Operating Members which established the specific rules of operation and pricing; and the Operating Guidelines, which provide standards and operating guidelines. The SAPP Agreement Between Operating Members and the Operating Guidelines are under review. • The SAPP has twelve member countries represented by their respective electric power utilities organised through SADC. • The SAPP has four working committees: the Environmental Sub-Committee, the Markets SubCommittee, the Operating Sub-Committee and the Planning Sub-Committee under a Management Committee which in turn reports to the Executive Committee. The Markets Sub-Committee is a new sub-committee that was created in April 2007 following the signing of the Revised Inter-Utility Memorandum of Understanding by the SAPP Executive Committee on 25th April 2007. Also created in April 2007 is the Coordination Centre Board to govern the activities of the SAPP Coordination Centre. • The SAPP coordinate the planning and operation of the electric power system among member utilities. • The SAPP provide a forum for regional solutions to electric energy problems. 4

Quality of Supply Mr. Adriano Jonas EDM (Mozambique) Operating Sub-Committee Chairperson At the 34th SAPP Meetings held in Gaborone, Botswana, from 15 to 16 February 2010, the Operating Sub-Committee agreed to revive the SAPP Quality of Supply (QOS) Working Group. Terms of reference for the working group were developed. The working group met for the second time from 11 to 12 November 2010 at Eskom Academy of Learning in Johannesburg, Republic of South Africa. The following were major outputs from the meeting: • The SAPP Quality of Supply Standard was finalised. • The SAPP QOS Meter Specification was finalised. • Points to install QOS facilities in the SAPP were identified. 1. System Demand Situation 4. SAPP SCADA System Project Due to power supply and other constraints, loadshedding programmes of varying magnitude were implemented in SAPP utilities especially during peak periods. In the year under review (2010/2011), the peak demand in the SAPP interconnected system was 43,664MW and that for Eskom, South Africa, was 36,970MW. Compared to the previous year, the SAPP interconnected system demand and the Eskom system demand were higher by 176MW and 265MW, respectively. The minimal growth in demand was attributed to various load management activities that were implemented during peak periods. Refer to the statistics section of this report for further details of system demand. The SAPP SCADA project kicked off in June 2010 following the award of a contract to ACTOM to supply, install and commission the Areva SCADA system at the SAPP Coordination Centre. The project equipment was delivered from France to Pretoria, South Africa, in December 2010 for hardware and software configuration. In January 2011, two personnel from SAPP Coordination Centre were attached to the contractor in Pretoria to participate in the configuration. From 16 February to 16 March 2011, a comprehensive maintenance and operations training course for the Areva SCADA System was organised for the SAPP in Massey, France. 2. Inter-Control Area Interchange Energy The SAPP Coordination Centre kept the account for the inter-Control Area interchange energy. InterControl Area inadvertent energy, imbalance energy and emergency energy were being reconciled monthly by all Control Areas. The SAPP Coordination Centre was generating monthly formal requests for financial settlement of imbalance energy or pay back in kind of inadvertent energy by Control Areas. Inadvertent energy and imbalance energy were being classified and summarised on monthly basis using a methodology based on hourly average values of power system frequency. The methodology and applicable energy rates were agreed jointly by the Markets and 14 Trainees and Trainers during the SAPP SCADA Project training in Massey, France
  16. 16. OPERATING SUB-COMMITTE REPORT Delegates from SAPP Coordination Centre, SEC (Swaziland), ZESA (Zimbabwe) and ZESCO (Zambia) participated in the training. In the first phase, the SAPP SCADA system will obtain data from the existing SCADA systems of the three Control Areas (Eskom, ZESA and ZESCO) via the ICCP (Inter-Control Centre Protocol) telecommunication channels. One of the objectives of the project is to facilitate efficient monitoring of the SAPP interconnected power grid. 5. The Telecommunications Working Group (TWG) The Telecommunications Working Group (TWG) is one of the working groups reporting to the Operating Sub-Committee. The TWG met in Mbabane, Swaziland, from 29 to 30 April 2010. The TWG resolved that optic fibre network should be the backbone of SAPP telecommunications link. The TWG identified a few gaps in the optic fibre network. The TWG estimated costs for linking the gaps and made proposals for implementation. The TWG is also the implementing organ of the SAPP SCADA project. On 7 December 2010, the TWG and ACTOM (supplier of the SAPP SCADA system) met in Pretoria, Republic of South Africa. At this meeting, the status of the SAPP SCADA Project was reviewed. Further, clarifications were made by SAPP and ACTOM on various key issues in the implementation of the project. 2010 for live testing and commissioning. However, the link was inaugurated on 12 November 2010 at Katima Mulilo in Namibia by the four Heads of State and Government of Botswana, Namibia, Zambia and Zimbabwe. The link provides an alternative asynchronous path for power interchange between SAPP members in the south and in the north, thereby easing congestion in the central corridor via Zimbabwe and Botswana. The 950km link is between the existing 220kV AC system at Gerus Substation in Central Namibia and the existing 220kV AC system at Zambezi Substation in the Caprivi Strip in Namibia, connected to Livingstone Substation in Zambia at the same voltage. The first phase monopole HVDC scheme has a capacity of 300MW but was limited to 50MW for commissioning and initial commercial operation between NamPower of Namibia and ZESCO of Zambia from October 2010. The link was not yet available for SAPP power wheeling in the year 2010. Zambezi Converter Station under construction on the Caprivi Strip in Namibia 7. System Disturbances 7.1 General Outlook Some members of TWG and officials from ACTOM at a meeting in Pretoria Refer to figure below for a general outlook of SAPP system disturbances. Main causes of the system disturbances were: adverse weather conditions especially in the rainy season, power oscillations, and isolated events of equipment vandalism and equipment failure. Refer to Appendix 1 for a summary of some major system disturbances reported on the SAPP grid. 6. The Caprivi HVDC Link The 350kV Caprivi HVDC Link was energised in May 15

The meeting also signed off the criteria for prioritizing transmission capacity where constraints and competing transactions prevail. 10. Acknowledgements Reported SAPP System Disturbances 7.2 Mitigation Measures In the year 2010/2011, power demand continued to rise in the SAPP power system against a condition of power deficit. Remarkable interchange energy imbalances were reported on the interconnectors. Also, system disturbances of varying magnitude and impact were experienced. I would like to thank all Operating Sub-Committee members who assisted me in various ways in meeting the challenges. Operating Members carried out recommended activities to mitigate occurrence and impact of system disturbances. These included enhancing information sharing by system controllers in real time, strict adherence to power transfer limits, returning to Mr. Adriano Jonas service generating units at a major power station in Operating Sub-Committee Chairperson Zimbabwe, re-tuning power system stabilisers on key generating units, and returning to service key Static Var Compensators (SVCs). 8. Revision of the SAPP Operating Guidelines After completing revision of the Inter-Utility Memorandum of Understanding (IUMOU), Agreement Between Operating Members (ABOM), the SAPP is now in the process of revising the Operating Guidelines (OG). The Operating SubCommittee formed a Task Team comprised of all SAPP members to carry out the revision. The Task Team met in November 2010 in Lusaka, Zambia. At the meeting, a consultant, PPA Energy, made a presentation on power system frequency bias and control performance standards in interconnected power systems. This assisted the Task Team in revising some guidelines and also developing other guidelines. 9. Joint Markets and Operating Sub-Committees Meeting The Joint Markets Sub-Committee (MSC) and Operating Sub-Committee (OSC) meeting on power wheeling was held at SAPP Coordination centre in Harare, Zimbabwe, on 28 March 2011. The meeting made resolutions on handling of counter power 16 Power line and substation in NamPower (Namibia)

OPERATING SUB-COMMITTE REPORT Date Utility Detail of disturbance Saturday 17-Apr-10 14h34 HCB At 14h34 on Saturday 17 April 2010, the generator unit assigned to the HVAC load (Mozambique) / at HCB Songo Power Station tripped. On the HCB-ZESA interconnector, 197MW ZESA (Zimbabwe) ZESA imports reversed to 86MW ZESA export. About two (2) minutes later, the 330kV HCB-ZESA interconnection tripped on three-phase main distance protection. Although energy interchange schedules were temporarily affected by the disturbance, no load was lost in the ZESA system. Prior to the disturbance, the 330kV HavenBulawayo and Hwange-Sherwood 1 lines were out of service for voltage control in ZESA. The HCB-ZESA interconnection was returned to service at 16h30 after the first attempt at 16h09 resulted in the feeder tripping at both ends upon closure. Sunday 02-May-10 10h18 ZESA (Zimbabwe) At 10h18 on Sunday 02 May 2010 the 330kV Insukamini – Bulawayo and Haven - Bulawayo lines in ZESA tripped on three-phase main distance protection due to suspected power swings induced by load rejection from the HVDC system. 330kV Insukamini – Hwange and Hwange-Sherwood 2 lines were out of service for planned maintenance and voltage control, respectively, prior to the disturbance. The SAPP interconnected power system was split. In the northern island, system frequency was observed momentarily dipping to 49.30Hz and rising to 51.00Hz. ZESA’s Insukamini load of about 89MW remained connected to the Eskom system. Energy interchange schedules on ZESA-ZESCO, HCB-ZESA and ZESA-BPC-Eskom were affected. The interconnected system was re-synchronised on the same day at 12h07. Wednesday 05-May-10 11h43 Wednesday 05-May-10 16h15 Friday 21-May-10 17h58 Eskom (South Africa) At 11h43 on 05 May 2010 Unit 3 at Matla Power Station generating 430MW tripped. A minute later, Unit 5 at Duvha Power Station generating 450MW tripped. At 11h47 Unit 3 at Matla Power Station generating 375MW tripped. The protection that operated was ‘reverse power’. Malta units tripped because of loss of condenser vacuum resulting from low level of cooling water well. The Duvha unit tripped because of low bunker levels. Power system frequency momentarily dropped to 49.60Hz and then stabilised at 49.75Hz. At Songo Power Station, the bus-coupler circuit breaker linking the HVDC and HVAC loads tripped on under-frequency protection. An output of about 220MW was lost from Apollo Converter Station. A 230MW reversal of power interchange flow was observed on the 400kV Matimba – Phokoje (Eskom-BPC) tie line. On the 330kV Songo-Bindura interconnector load increased from 185MW to 256MW. Later, output from Apollo Converter Station was restored to normal at 11h51. Matla Unit 6, Duvha Unit 5, and Matla Unit 5 were back on load same day at 13h08, 15h20 and 16h11, respectively. ZESA (Zimbabwe) At 16h15 on Wednesday 05 May 2010 330kV Sherwood – Chertsey line tripped on main distance protection due to suspected power swings induced from networks external to ZESA. 330kV Haven – Bulawayo and Hwange-Sherwood 1&2 lines were out of service for voltage control prior to the disturbance. The interconnected power system was split. A condition of over-frequency was observed in the northern island. Kariba South Unit 5 tripped on over-frequency. ZESA’s Insukamini, Bulawayo, Chertsey and Tokwe loads totalling about 250MW remained connected to the Eskom system. Energy interchange schedules on ZESA-ZESCO, HCB-ZESA and ZESA-BPCEskom were affected. The interconnected system was re-synchronised on the same day at 17h48. Eskom (South Africa) / LEC (Lesotho) Merapi 180MVA 275/132kV transformer 1 tripped due to a faulty transformer tap changer. While this transformer was still out of service, the other transformer in parallel, the Merapi 180MVA 275/132kV transformer 2, also tripped on 17 June 2010 at 08h25. The supply to LEC was interrupted but some loads were then restored through the 88kV network. Merapi 180MVA 275/132kV transformer 1 was returned to service at 20h01 on 17 June 2010 while Merapi 275/132kV transformer 2 tap changer was being repaired. 17
  19. 19. OPERATING SUB-COMMITTE REPORT Date Utility Detail of disturbance Friday 18-Jun-10 10h09 ZESCO (Zambia) / At 10h09 on Friday 18 June 2010, the following 330kV transmission lines tripped ZESA (Zimbabwe) on distance protection in the ZESCO system: Kariba North – Leopards Hill 1&2, Kafue Gorge – Leopards Hill 1&2, and Kafue West – Leopards Hill. Also, six (6) units at Kafue Gorge generating 940MW and 3 units at Kariba North Bank generating 480MW tripped. The Victoria Falls Power Station was islanded from the ZESCO grid at Muzuma Substation but remained interconnected to the Caprivi HVDC link. This system disturbance was initiated by a fault on Kariba North - Leopards Hill line number 2. Upon clearing the fault, the yellow phase interrupter chamber of the 330kV line circuit breaker at Kariba North ruptured. In the ZESA system, 330kV Kariba South – Alaska lines 1,2&3 tripped on main distance protection and Kariba South units 1 to 6 generating 734MW tripped on over-frequency. Inter-Control Area energy trading schedules were affected. At 12h07 a generator tripped at Songo and then 330kV Songo – Bindura and Selous – Norton lines tripped on over-voltage. Interconnection between ZESA and HCB and between ZESA and ZESCO were re-established at 16h18 and at 22h02, respectively. Thursday 09-Sep-10 08h17 SNEL (DR Congo) The following tripped at Kolwezi 500kV HVDC Converter Station terminal : - Synchronous condenser number 02 ; - Harmonic filter number 01 - Autotransformer 220/120 kV - 100 MVA Also, machines 1 and 2 at NSEKE power station and machines 2 and 3 at KONI power station tripped. The disturbance was caused by the tap changer failure on 51MVA 132/220kV output converter. About 60MW power inadvertently flowed into SNEL from SAPP. This was then limited by load shedding that was carried out by SNEL. The transformer tap changer was repaired and all the equipment was restored to service by 11h41 on the same day. Sunday 24-Oct-10 08h30 Eskom (South Africa) / LEC (Lesotho) The 275kV Harvard-Merapi 1 line was taken out of service for routine maintenance. About half an hour later, low voltages were experienced on the Tweespruit and Merapi 132kV networks. Then Clocolan 132/88kV transformer 2 and Tweespruit 132/88kV transformers 1&2 tripped on ‘tap-changer lock-out’ and ‘regulation abnormal’ protection. Supply to LEC was interrupted. The outage of 275kV Harvard-Merapi 1 line was then cancelled and the line was returned to service at 08h55. Tweespruit and Clocolan transformers were returned to service at 09h51 and 11h05, respectively. Tuesday 26-Oct-10 15h28 ZESA (Zimbabwe) The 750MVA 400/330kV Insukamini Transformer T3 tripped on 11kV neutral displacement protection due to inadvertent opening of the 11kV tertiary blue phase D-link. The SAPP System split and about 109MW interchange (ZESA-NamPower and ZESCO-Eskom) was temporarily interrupted. The transformer was returned to service at 21h15 after checks and tests; and the interconnection was re-synchronised at 21h30 and normal power interchange resumed. Wednesday 03-Nov-10 15h54 ZESA (Zimbabwe) The 330kV Dema-Bindura line faulted on all 3 phases, tripped and locked out. The 330kV Songo-Bindura line then followed to trip on over-frequency. The SAPP system split and 257MW imports for ZESA/Eskom/BPC curtailed. The cause of the fault was a collapsed vandalised tower and conductors were on the ground. The two lines remained out of service. HCB/EDM-North were isolated on the AC interconnection for a week until the tower was repaired. Tuesday 09-Nov-10 13h29 18 BPC /Eskom/ ZESA At 13h29 132kV Dwaalboom - Spitskop line 1 tripped. At 13:30 400kV Matimba Phokoje line tripped. Same time 400kV Phokoje-Insukamini line inter-tripped. The trips were due to lightning activities. BPC load of about 400MW was connected to only two 132kV lines and while manual load-shedding was being carried out, one of the two lines (132kV Dwaalboom-Spitskop line 2) also tripped at 13h42. Two generators tripped at Morupule on overload. In restoration, the Eskom-BPC 132kV lines were returned to service by 14h03. The 220kV Bulawayo - Francis Town line was put in service to supply the northern island in BPC. The Phokoje 400kV supplies were re-established at 06h41 on the following day and load restoration commenced immediately. The 400kV Insukamini – Phokoje interconnector was re-synchronized at 08h14 on the 10 November 2010.
  20. 20. OPERATING SUB-COMMITTE REPORT Date Utility Wednesday 15-Dec-10 11h52 HCB (Mozambique) At 11h52:32 HVDC Converter Bridge 4 tripped at Apollo. Then at 11h54:30 one bridge tripped at Songo. At 11h54:38, load rejection control signal (60% of 720MW during 528ms) was received at Songo leading to tripping of bus coupler on ‘excess energy’ protection. Due to low HVAC load, Songo was operating with 4 units on DC bus bar, feeding the AC bus bar via bus-coupler. After bus-coupler trip, Songo-Bindura and EDM-N lines did not trip. So EDM-N imported up to 108MW from the SAPP AC network. Bus-coupler was closed at 11h56:50 and the scheduled transactions via Songo-Bindura line were normalised at 12h01:18. Monday 03-Jan-11 13h48 BPC (Botswana) / HCB (Mozambique)/ ZESA (Zimbabwe) The 400kV Insukamini-Phokoje interconnector tripped on distance protection blue and yellow phases zone A&B due to suspected lightning activity. This was followed by tripping of 220kV bus coupler breaker at Songo on ‘max angle deviation exceeded’ protection. (Angle measured between Apollo HVAC bus bar and Songo HVAC bus bar increased from 39º to 146º). Impedance variation on the HVAC link was observed by the controller (GMPC) at Songo. No load was lost in ZESA. Interconnection was re-established at 14H05 at Insukamini. And, bus-coupler was closed at 14h12:08 at Songo. Saturday 28-Jan-11 06H23 HCB (Mozambique)/ Eskom (South Africa) Apollo Converter Station lost an output of about 1550MW due to loss of five generating units at HCB Songo Power Station. Power system frequency dropped from 50.05Hz to 49.4Hz at worst point then stabilised at 49.89Hz. To arrest frequency decay, from 06H24 to 06H42 the following generating units auto-started in Eskom: Port Rex 1, 2 &3, Acacia 1,2 &3; also Palmient unit 2 shutdown from pump mode; further, Hillside Potline 2 load of about 440MW was load shed. About 150MW inadvertently and temporarily flowed into Eskom on the Eskom-ZESA tie-line. Sunday 29-Jan-11 23H00 Detail of disturbance ZESA (Zimbabwe) Due to power swings, the 330kV Chertsey-Sherwood and Hwange-Sherwood 1 lines tripped on distance protection (back-up) and generators 2 & 4 at Hwange on sensitive power protection and generator 5 at Kariba South on over-frequency. 330kV HavenBulawayo and Hwange-Insukamini lines were out of service. The SAPP system was split into two islands. ZESA did not lose any load but about 250MW of its load was temporarily fed from Eskom. The SAPP system synchronism was re-established at 00h53 on 30Jan11. 19
  21. 21. MARKETS SUB-COMMITTE REPORT 2. DAM Participation Levels Mr Adérito Sousa EDM (Mozambique) Markets Sub Committee Chairperson 1. Introduction. It gives me great pleasure as a newly elected Markets Sub Committee Chairperson, to report on the SAPP market activities for the year ended 31st March 2011 and in particular the developments on the newly launched SAPP competitive Day Ahead Market (DAM). In the past two years we have been concentrating our efforts on communicating the SAPP DAM market benefits and differentiation to enable all stakeholders and potential investors to understand our market and the underlying methodology. We have also been working on the issues that needed to be resolved prior to market opening. This message was well received as evidenced by the live operation of the SAPP DAM as from the 15th of December 2009. Since then members have realised the benefits of the DAM as it plays a pivotal complimentary role to the traditional bilateral trading arrangements that have been characterising the SAPP trading portfolio since SAPP formation. However challenges on the DAM operation and trading in general are still there and these range from diminishing generation capacity, transmission constraints and mismatch of prices between sellers and buyers bids. It is my strong conviction that these are not insurmountable challenges and with concerted efforts as evidenced from the efforts being put by SAPP as a family and our cooperating partners such as the Government of Norway and Sida, the dream for a competitive market in the SAPP will be fully realised. 20 A total of eight members have signed the DAM governance documents as of 31st March 2011. These are Eskom, NamPower, BPC, SEC, ZESCO, EDM, ZESA and LEC. On average a total of five members have been active on the market during the period under review. Non SAPP members have also shown interest to participate in the SAPP DAM market. It should be noted that the revised SAPP governance documents have opened up participation of current non SAPP members subject to meeting the conditions to participate as prescribed in the DAM Book of Rules. No market abuse or misbehaviour was recorded on the market during the period under review. 3. DAM Market Performance Highlights 3.1 Traded Energy Volumes A total of 395.642 GWhr Sale Bids and 258.418 GWhr Buy Bids were received during the period 1st April 2010 to 31st March 2011. Out of this, a total of 27.397 GWhr was traded. A lower figure was traded when compared to bids and offers submitted to the market largely due to mismatch of prices between sellers and buyers and transmission constraints experienced on the market. There was a significant rise on the volumes on the market when compared to the 31.450 GWhr Sale Bids, 7.725 GWhr Buy Bids and 0.545 GWhr Traded energy realised in the previous year. Below is a summary of the yearly market performance in terms of energy volumes submitted and those that were actually traded.
  22. 22. MARKETS SUB-COMMITTE REPORT Fig 3.1 Total Energy Offered and Traded on DAM for the Year Ended 31st March 2011. Below is a summary of the shares of trade on the DAM and Bilateral trading platforms from the 1st of April 2010 to the 31st of March 2011. Fig 3.2 Market Share Distribution Between Bilateral and DAM Trades for the Year Ended 31st March 2011. The market achieved commendable progress although there was no market cross during the first four months of the financial year, that is, from April to July 2010. Trading however picked up in August 2010 reaching a climax in January 2011. During the period under review, market cross was largely achieved for more than 50% of the time and for an average of 20 hours in a day. It is also interesting to note that trading took place during peak, standard and off peak periods and 3.3 DAM Market Clearing Prices (MCPs) in certain days, trading occurred for all the 24 hours. There were more sale bids than buy bids for most of The average market clearing prices continued to rise with March 2011 recording the highest average at the time during the year under review. USc3.90/kWhr. Below is a summary of the average monthly MCP prices for the year ended 31st March 3.2 Market Share Distribution 2011. A total of 27.397 GWhr was traded on the DAM during Fig 3.3 Average Monthly DAM Market Clearing the period from 1st April 2010 to the 31st of March 2011 when compared to 9, 516.515 GWhr traded on Prices (MCPs) for the Year Ended 31st March 2011. the bilateral trading platform during the same period. This resulted in the average market share for DAM trades of 0.29%. 21
  23. 23. MARKETS SUB-COMMITTE REPORT The reason for the drop in average MCP prices from July 2010 to September 2010 was largely due to increased competition as more sellers entered on the market with the buy bids not increasing. However from September to March 2011, the average MCP prices were generally increasing due to increased competition for power on the market that was coupled with transmission constraints. Market clearing prices on DAM were very competitive when compared to bilateral trades for the period under review. 3.4 Revenues Realised from the DAM Market A total of USD975,855 was exchanged on the DAM market for the period from the 1st of April 2010 to the 31st of March 2011. Of this USD757,767 was exchanged between buyers and sellers of energy on the market, USD69,873 and USD 15,683 was distributed to respective Transmission System Operators (TSOs) as Wheeling and Losses revenues respectively, USD54,793 was received by the Market Operator as Administration fees and a total of USD77,739 was collected as Congestion Income, that is income arising as a result of transmission constraints. Below is a summary of the revenues realised during the year under review. Fig 3.4 DAM Revenues Realized for the Year Ended 31st March 2011. 22 MSC delegates at the 5th MSC meetings in Harare, Zimbabwe, 22nd April 2010. 4. SAPP Trading Challenges The SAPP market faced three key challenges during the period under review. These are briefly outlined below. 4.1 Power Supply Challenges Despite the fact that some SAPP members have excess generation capacity while others have generation deficits, in general, the SAPP is currently in a generation shortfall. This situation has had a tendency of encouraging bilateral trading as a means of ensuring security of supplies as opposed to relying more on the short term SAPP DAM market. As a result, there are generally very few sellers of power on the DAM during peak and standard times. Where such power is available, the prices are generally quite high. As a result this has had an impact on trading on the DAM market. This situation is likely to continue up until the SAPP has installed adequate generation capacity most likely from year 2014 provided the current generation expansion plans are implemented on schedule. One approach to increase liquidity in the DAM is to trade bilateral contracts through the DAM and implement Contract for Differences (CfDs). The SAPP has considered this approach but the fear is that there is more exposure for buyers of power when bilateral contracts are cleared through the DAM.
  24. 24. MARKETS SUB-COMMITTE REPORT 4.2 Mismatch Between Buyers and Sellers Bid prices One of the main challenge why trading has been relatively low on the DAM market when compared to bids submitted, has been the mismatch between buyers and sellers ask prices. The sellers are offering prices that buyers are apparently not prepared to pay. As a result there is no matching for most of the time. This challenge can only be overcome if traders exercise economic dispatch and optimization of their entire supply and demand portfolios as opposed to taking advantage of the current generation shortfall in the SAPP when pricing bids. For that to happen, there is need for adequate confidence of getting power on the DAM market. 4.3 Transmission Constraints Transmission constraints, especially along the SAPP central corridor, have had significant impact on both bilateral and DAM trading during the period under review. On some corridors, existing contracts are more than double available transmission capacities. Transmission constraints on the SAPP grid can also be witnessed by the significant difference between matched and actual traded DAM volumes as given in Fig 4.1 below. Fig 4.1 Impact of Transmission Constraints on DAM Trading for the Year Ended 31st March 2011. It can be noted from Fig 4.1 above that for the year under review, a total of 44,408 MWhr was matched but only 27,397 MWhr was actually traded. As a result, a total of 17,011 MWhr or 38.3% of what was matched could not be traded due to transmission constraints. 5. Transmission Capacity Access & Allocation The Markets and Operating Sub Committees developed criteria for allocating transmission capacity in the SAPP. The criteria promotes the principle of open access to transmission facilities in the SAPP at the same time allowing the transmission developers first right to access of their transmission facilities. The criteria are also built on the principle of the Grandfather’s Rule where old contracts have preference over newer contracts. In addition it also recognises the need to support one another during emergencies. 6. Market Guidelines Development The Markets Sub Committee established a Task Team to develop Market Guidelines for SAPP. The MSC Task Team on Market Guidelines held their first meeting in November 2010 in Lusaka, Zambia. A lot of progress was made and recommendations have been made for MSC consideration. The Guidelines will embrace all the trading platforms in the SAPP and are designed to ensure co-ordinated trading among SAPP Members, efficient use of shared facilities and to achieve high levels of system reliability of the interconnected SAPP system. The Guidelines specify how each of the identified SAPP markets shall be developed, operated and managed. So far, guidelines for Bilateral trading, 23
  25. 25. MARKETS SUB-COMMITTE REPORT Over the Counter (OTC) trading and the Day Ahead Market trading platforms have been completed. 7. Market Surveillance In order to ensure fair play among market participants, there is need for market surveillance. As such, the SAPP has agreed to establish a Markets Monitoring & Surveillance Team (MMST) that will oversee the market surveillance portfolio in the SAPP. The Terms of Reference for the team were developed and the full operation of the team will await market performance. Meanwhile the Coordination Centre Manager is responsible for the market surveillance functions. 8. Capacity Building Operating a competitive market requires continuous capacity building of the SAPP members and in particular the Markets Sub Committee that is expected to spearhead the development of all the possible market trading portfolios in the SAPP. The development and operation of a competitive market comes with a number of challenges and for SAPP, this is not an exception. The SAPP is currently transforming from a cooperative pool to a competitive power pool. Such transitions require a lot of capacity building among the SAPP members. During the period under review, the SAPP managed to undergo a number of capacity building activities that were very useful in the implementation and operation of the DAM market. Below are some of the training activities that were undertaken. 8.1 Study Tour to Europe The SAPP undertook a study tour to Europe on electricity power markets development and implementation on 20-30 July 2010 as part of the European Union funded Capacity Building Programme for SAPP. The study tour was an eye opener to members and the immediate results were increased volumes of trade for the period August 2010 to date. 24 Delegates who attended the Study Tour in Europe in July 2010. 8.2 Country Seminars The Government of Norway and Sida provided funding for country seminars on DAM trading. Provision was made to hold country seminars in each of the SAPP members. The main purpose of the seminars is to share on opportunities and challenges (regulatory, policy and technical issues) that may be encountered by the region as it implements the competitive electricity market. One seminar for all SAPP members, respective SADC ministries of energy, RERA, large consumers and Independent Power Producers was held in August 2009. During the period under review only one country seminar was held for South Africa. The seminar was attended by SAPP CC, RERA, Eskom, NERSA, DoE in SA, IPPs, Large User groups etc. 9. Traders and Operators Forum The 7th session of the SAPP Traders and Operators forum was held in Maseru, Lesotho from the 20th to the 21st of October 2010. Forty participants from twelve members shared hands on challenges and experiences on operational issues and market developments.

Acknowledgements I would like to express my gratitude to the first and outgoing Markets Sub Committee (MSC) Chairperson, Mr Michael Barry of Eskom (South Africa) for his sterling effort to address all the outstanding issues and ensure that the market is opened for live trading on the 15th of December 2009. I would also like to pay special tribute to our cooperating partners and in particular, the Government of Norway, Sida, the European Union etc whose continued commitment and support towards the implementation of the SAPP competitive market is very much appreciated. The members of the Markets Sub Committee (MSC) have also been very supportive and their efforts can be witnessed by the number of issues they resolved for the good of the market. The SAPP CC team headed by the Centre Manager, Dr Lawrence Musaba, also worked tirelessly to ensure the success of the trading arrangements in the SAPP. Market participants and their respective traders and system controllers have been very supportive and their continued participation immensely contributed towards the success of the market during the period under review.

ENVIRONMENTAL SUB-COMMITTEE (ESC) ANNUAL REPORT Environmental and Social Impact Assessment have been approved on the Mozambique side, while Malawi is yet to decide on the future of the project. 2.4 Zambia-Tanzania-Kenya Interconnector The Environmental and Social Impact Assessment report has been completed and approved on the Zambian side. On the Tanzanian side, the situation is as follows; Mrs. Matseliso Moremoholo LEC (Lesotho) Environmental Sub-Committee Chairperson 1. Introduction The SAPP continues to provide support to the Environmental Sub-Committee (ESC) to ensure sustainable energy developments through sound economic, environmental and social practices. This support has seen environmental management issues taking centre stage to most activities and projects being implemented in the region. 2. Environmental Status of SAPP Transmission Projects 2.1 Zimbabwe-Zambia-Botswana-Namibia Interconnector (ZIZABONA) • Mbeya-Irringa line: The feasibility study including the ESIA has been financed by NELSAP and consultant for this activity will soon be appointed soon. • Way leave demarcation is being done along the IringaShinyanga 400bkV line passing through Dodoma and Singida. 3. Climate Change The Sixteenth Conference of Parties (COP 16) to the United Nations Framework Convention on Climate Change (UNFCCC) was held in Cancun, Mexico in November/December, 2010. Mr Johnson Maviya represented SAPP. The highlights of the conference are: • Acceptance of operational reforms to expand and streamline Clean Development Mechanism (CDM) activities • Availability of a loan scheme for countries with fewer than 10 registered CDM projects • All member states (signatories to the UNFCCC) including all SAPP member states should complete inventories of GHGs as a requirement under the COP. • USD 30 billion to be made available to developing countries for mitigation and adaptation needs. The next conference, COP 17 will be held in Durban, South Africa in November/December, 2011. Members from the four countries to be linked by the high voltage transmission infrastructure have engaged a consultant to undertake studies covering technical, marketing and environmental studies. Environmental Impact Assessment (EIA) study reports for the project were handed over to the consultant. In terms of environmental issues, further progress will only commence after the consultant has completed studies and mapped the way forward. 4. Renewable Energy and Energy Efficiency 2.2 DRC-Zambia Interconnector 4.1 Renewable Energy World Bank financing is available for the DRC portion. The project is now at compensation stage and affected communities will be compensated. The Environmental and Social Impact Assessment (ESIA) report has been completed and environmental consents to implement the project have been secured. Renewable Energy is a priority in the SAPP region. The goal is to utilise and benefit from significant renewable energy resources that exist in the region, adopt energy efficiency practices and achieve maximum energy efficient utilisation, and thus cutting down on energy related GHG emissions as the region’s contribution towards climate change stabilization. In this context the SAPP defines renewable energy as any form of energy from solar, geothephysical or biological source that is 2.3 Mozambique- Malawi Interconnector Contracts for feasibility studies as well as the 26
  28. 28. ENVIRONMENTAL SUB-COMMITTEE (ESC) ANNUAL REPORT replenished by natural processes at a rate that equals or exceeds its rate of use. The SAPP aims at exploiting the following forms of energy: • Wind • Solar Solar Hybrid installation in Namibia – described as one of the largest in Africa • Geothermal • Hydropower • Modern Bio-mass The SAPP aims at increasing the contribution of Renewable Energy from the current 20% to 25% by 2020 if all planned projects are implemented. 4.2 Energy Efficiency The SAPP is implementing Energy Efficiency measures as a means of meeting increasing demand. Energy Efficiency is concerned with delivery of energy services with reduced energy consumption. This can be achieved through technical changes, fuel substitution and demand side management practices. All SAPP member states have initiated energy efficiency initiatives which include the introduction of energy saving bulbs known as Compact Fluorescent Lamps (CFLs), Solar Water Heaters, Industrial and Commercial load shifting, Hot Water Load Control (HWLC), Technical Audits, commercial lighting and power correction factor. The aim is to save 1,650 by 2014. South Africa has set the target for improved energy efficiency at 12% by2015. The strategy includes Eskom’s Demand Side Management (DSM) which aims to save 4, 255 MW over a period of 20 years. 4.2.1 Compact Fluorescent Lamps (CFL) Disposal. Used CFLs have been classified has hazardous waste because of mercury contained in the bulbs and as such should be disposed of just as hazardous waste. The SAPP developed guidelines for the safe disposal of CFLs for utilities to use when advising municipalities and local authorities on the safe disposal of used CFLs. Each utility carried out an assessment of the capacity to handle and dispose CFLs in an environmentally friendly manner. Only South Africa and Namibia were found to have suitable facilities for the safe handling and disposal of CFLs. The rest would need to develop facilities that would see a separation of hazardous waste from nonhazardous waste and ensure safe disposal of hazardous waste. The SAPP would therefore assist municipalities and local authorities with best practices for the safe collection, handling, transportation and disposal of used CFL at a hazardous waste disposal site. 5. PCB Phase-out in the SAPP During the year under review, the SAPP was able to secure funding from United Nations Environmental Programme (UNEP)for the implementation of the PCB Phase-out project in the SADC region. All SAPP member states including Mauritius and Madagascar would benefit from the fund as long as the countries submit their National Implementation Plans (NIPs) to United Nations Environmental Programme. The project would include: • Capacity building at regional and SAPP utility level • Detailed inventories of all PCB contaminated equipment at SADC utilities • Development and tracking system for PCB contaminated equipment • Development of plan from risk based assessment for gradual replacement of PCB contaminated equipment and elimination • Environmentally Sound Services (ESS) available, collection system (oil and transformers), storage and transportation. • Awareness raising of key stakeholders, governments, public and private sector. The project expected to start in 2012 and end in 2017. 27

  43. 43. FINANCIAL STATEMENTS STATEMENT OF DIRECTORS’ RESPONSIBILITY The Directors of Southern African Power Pool “the Organisation” are responsible for the maintenance of adequate accounting records and the preparation and integrity of the financial statements and related information. The auditors are responsible for reporting on the fair presentation of the financial statements. The Directors are also responsible for the Organisation’s systems of internal control. These are designed to provide reasonable, but not absolute, assurance as to the reliability of the financial statements, and to adequately safeguard, verify and maintain accountability for the Organisation’s assets, and to prevent and detect misstatement and loss. The systems are implemented and monitored by suitably trained personnel with an appropriate segregation of authority and duties. Nothing has come to the attention of the Directors to indicate that any material breakdown in the functioning of these controls, procedures and systems has occurred during the year under review. The financial statements have been prepared on the going concern basis since the Directors believe that the Organisation has adequate resources in place to continue in operation for the foreseeable future. The financial statements for the year ended 31 March 2011 set out on pages 44 to 67 were approved by the Board of Directors on 13 January 2012 and signed on its behalf by:DIRECTORS .............................................. .............................................. 19 September 2011 42
  44. 44. FINANCIAL STATEMENTS: REPORT OF INDEPENDENT AUDITORS Report on the financial statements to the members of Southern African Power Pool We have audited the accompanying financial statements of Southern African Power Pool, which comprise the statement of financial position as at 31 March 2011, the statement of income and expenditure, statement of changes in shareholders’ funds and statement of cash flows for the year then ended, and a summary of significant accounting policies and other explanatory notes, as set out on pages 44 to 67. Directors’ responsibility for the financial statements The Directors are 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 control 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 these financial statements based on our audit. We conducted our audit in accordance with International Standards on Auditing. Those 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. An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the financial statements. The procedures selected depend on the auditor’s judgment, including the assessment of the risks of material misstatement of the financial statements, whether due to fraud or error. In making those risk assessments, the auditor considers internal controls relevant to the entity’s preparation and fair presentation of the financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the entity’s internal control. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of accounting estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion. Opinion In our opinion, the financial statements, in all material respects, give a true and fair view of the financial position of Southern African Power Pool as at 31 March 2011 and of its financial performance and its cash flows for the year then ended in accordance with International Financial Reporting Standards. ..............................................

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Th e principal accounting policies of the Organisation, which are set out below, are consistent in all material respects with those applied in the previous year. 5.1 Basis of preparation Th e financial statements have been prepared on the historical cost basis. Historical cost is generally based on the fair value of the consideration given in exchange for assets. 5.2 Reporting framework and statement of compliance Th e financial statements have been prepared in conformity with International Financial Reporting Standards (IFRS), promulgated by the International Accounting Standards Board (IASB), which includes standards and interpretations approved by the IASB as well as International Accounting Standards and Standing Interpretations Committee (SIC) interpretations issued under previous constitutions (IFRS’s). The financial statements are based on statutory records that are maintained under the historical cost convention. 49
  51. 51. FINANCIAL STATEMENTS NOTES TO THE FINANCIAL STATEMENTS: CONTINUED for the year ended 31 March 2011 5. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued) 5.3 Property and equipment Property and equipment are stated at cost less depreciation and impairment losses. Depreciation is calculated on the straight-line method so as to write off the cost of assets to their residual value over their estimated useful lives at the following rates: Computer equipment 33.33% Office equipment 20% Office furniture and fittings 10% An item of property and equipment is derecognised upon disposal or when no future economic benefits are expected from its use. 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 statement of income and expenditure in the year the asset is derecognised. The Directors make an assessment of the useful lives and residual values of the assets on an annual basis. 5.4 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 that are readily convertible into known amount of cash and subject to insignificant risk of change of value. 5.5 Special funds Funds granted for specific purposes are accounted for separately as Special Funds in the statement of financial position. 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 Special Fund. The amount expended is recognised as income on a systematic and rational basis over the period necessary to match them with the related costs. Grants related to assets are capitalised with the amount utilised for the period amortised to the income and expenditure account. 5.6 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 can be made of the amounts of the obligation. 5.7 Employment benefits Employee benefits are the consideration given by the Organization in exchange for services rendered by employees. In summary such benefits are: Short-term benefits Benefits earned by employees under normal employment terms including salaries, wages, bonuses and leave pay. These are expensed as earned and accordingly provisions are made for unpaid bonuses and leave pay. Post-employment benefits 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 statement of income and expenditure when due. 50
  52. 52. FINANCIAL STATEMENTS NOTES TO THE FINANCIAL STATEMENTS: CONTINUED for the year ended 31 March 2011 5. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued) 5.8 Revenue recognition Funds income received is based on a set budget agreed upon by all members of the Organisation. 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. Interest revenue is recognised when it is probable that the economic benefits will flow to the Organisation and the amount of revenue can be measured reliably. Grant income for specific projects is recognised when the respective expenditure has been incurred. 5.9 Trade and other receivables Receivables are measured at amortised cost. Appropriate allowances for estimated irrecoverable amounts are recognised in the statement of income and expenditure when there is objective evidence that the asset is impaired. 5.10 Trade and other payables Payables are measured at amortised cost. 5.11 Foreign currency transactions Transactions in currencies other than the functional currency are recorded at the rates of exchange prevailing on the dates of the transactions. At the end of each reporting period, monetary items denominated in foreign currencies are retranslated at the rates prevailing on the reporting date. Exchange differences arising on the settlement of monetary items, and on the retranslation of monetary items, are included in the statement of income and expenditure. 5.12 Day Ahead Market (DAM) bank accounts The DAM operates a substantial number of accounts which are maintained at Stanbic Bank Botswana Limited. The purpose of these accounts is primarily for clearing purposes, accounting for market transactions, security custodial services, administration fees, wheeling fees and transmission losses. 6. CRITICAL JUDGEMENTS IN APPLYING THE ENTITY’S ACCOUNTING POLICIES I n the process of applying the Organisation’s accounting policies, management made the following judgments that have a significant effect on the amounts recognised in the financial statements: Useful lives and residual values of property and equipment. Th e Organisation assesses useful lives and residual values of property and equipment each year taking into account past experience and technology changes. The Directors have assessed the useful lives in the current year and determined that changes to the current useful lives are not necessary. The residual values have been based on the market values of the assets. 51
