CHAIRMAN’S STATEMENT
On behalf of the Board of Directors, I am pleased to present the Annual Report and FinancialStatements of the Central Electricity Board for the financial year ending 31 December 2003.
The year under review was marked by a net financial rebound. A better control of operatingcosts together with the positive impact of the tariff increase in January 2002 contributed tothe improvement of our financial situation, as evidenced by the significant increase in ournet profit (MUR 617.9 million as compared to MUR 179.6 million for the year 2002).However, the CEB still has a substantial accumulated deficit of MUR 1.8 billion, which weaim to recoup over the next 5 years.
During the year, much progress was achieved as regards the corporatisation process,initiated in Year 2002, in line with Government’s long-term strategy to reform the PowerSector. Major issues regarding the change of status of the CEB into a new company, such asthe legal framework, corporate governance, business structure and transfer of personnel,were addressed. The draft constitution of the CEB Successor Company was finalised andsubmitted to the Government for approval. Following a recommendation of the Ministry ofPublic Utilities, a Technical Committee on Corporatisation, consisting of representatives ofManagement, Unions and the Ministry, was constituted. The mandate of the tripartitecommittee was to act as a communication platform regarding possible concerns,apprehensions and mistrust associated with the corporatisation process. Five meetingswere held and the highlights of the minutes were forwarded to the Ministry.
for the year ended 31 December 2003
General Review
The restructuring of the CEB, under way since last year, continued in 2003 with the re-engineering of the Finance Department and the recruitment of a Chief Finance Officer tosteer the financial activities of the CEB. In pursuance of the merging of the Commercial andTransmission & Distribution Departments and the setting up of 3 Distribution Areas, talkswere held with Trade Unions with a view to fully explaining the purpose of the change andenlisting the unreserved collaboration of employees at large. The discussions will continuein the coming year, until the merging exercise really takes off.
As forecast, there was a growth in demand in Year 2003. The peak demand, recorded inDecember, reached 323.8 MW, an increase of 4.93% with respect to the previous year. Theenergy sold showed an overall increase of 7.74% and the CEB reached a customer base of338 563 in December, which represents an increase of 2.59% over the previous year.
To meet the growing energy needs of the country, planning for additional generatingcapacity in the short to mid-term future remained high on our agenda. Following theRequest for Proposals in December 2002, an agreement was reached with CompagnieThermique du Sud (CTDS) for the supply of electricity from a 30 MW coal-fired steam plant.CTDS is expected to be operational by October 2005. A feasibility study in relation to theproposed extension of the St Louis Power Station, where we plan to install three 10-12 MWDiesel Generator Units, was carried out. In December, another Request for Proposals, inrespect of 60 to 70 MW generating capacity fired by bagasse and a complementary fuel,was issued. Once implemented, these projects will enable the CEB to establish a strongbase for a stable supply of electricity, in line with the growth forecast in energy demand.
This year has also seen the taking of major decisions regarding the upgrading of ourinformation system. Following the issue of selective Request for Proposals, a consortiumconsisting of Accenture (South Africa) and DCDM was chosen for the implementation of anew enterprise wide information system. The new system, based on System ApplicationProducts (SAP), will be operational by October 2004 and will enable the CEB to re-engineer,streamline and modernise its major business processes.
The way forward lies in the dedication and commitment of our employees andmanagement team, converging on the attainment of organisational objectives. Theprogress achieved during the year in key peformance areas is an eloquent testimony to theefforts of both employees and Management towards reaching this common goal. On behalfof the Board, I would like to express my sincere appreciation to all concerned.
Last but not least, I would like to extend my thanks to our valued customers and otherstakeholders for their ongoing support to and confidence in the CEB.

Regular consultations between Management and the three Unions, namely the CEB StaffAssociation, the Union of Employees of CEB and the CEB Workers Union, have helped tomaintain mutual understanding and cooperation throughout 2003.
The Unions participated actively in several meetings of the Steering Committee set up inAugust 2003 to carry out a Job Evaluation exercise for employees posted in Rodrigues.
Pursuant to a Memorandum of Understanding signed in December 2000, Managementreached an agreement with the CEB Staff Association (in March 2003) and with the CEBWorkers Union (in November 2003) on a salary adjustment, effective as from 1 July 2002,and a provision to carry out a Job Evaluation exercise in 2004.
Following a recommendation of the Minister of Public Utilities at a Tripartite meeting heldon 30 June 2003, a technical committee was constituted to discuss the change of status ofthe CEB into that of a Corporation. The deliberations of the committee, comprising of CEBManagement, a representative of the Ministry and representatives of the three Unions,were meant to dispel any doubts or misunderstanding associated with the change. Fivemeetings were held, providing the Trade Unions with the opportunity to express theirconcerns regarding this matter.
Management also met regularly with the Unions to discuss the re-structuring of the T&DDepartment, thus enabling both sides to examine thoroughly all the issues associated withthe merger process.
Our two football teams (Veterans and First) were involved in five major tournaments. TheVeterans won the Cercle des Copains Veterans Tournament, whereas our first team finishedas runner-up in the F.M.S.C Inter-Firm Football Championship.
The CEB was once again the overall winner at the Inter-Island Sports competition betweenCEB and Electricité de France de L’Ile de la Réunion, a yearly event which is a source of greatmotivation for our sportsmen. Our football teams and our tennis men were victoriouswhereas the visitors proved to be too strong for us at Bowls.
A special end of year party, held at Gold Crest Hotel, brought together, for the first time,the pensioners and the widows of deceased employees who, in the past, used to be invitedto the Head Office end of year party. On that occasion, according to an established custom,a present was handed over to each guest.
The Welfare Section was actively involved in the celebrations marking the 100thanniversary of the Tamarind Falls Power Station, which saw the production of a film, theissue of a souvenir and the exhibition of a painting by Sylvio De Lapeyre, Inspector of Worksat Hydro Section.
Football and volleyball matches, as well as various indoor activities were organised duringthe year in order to entertain the employees and provide them with physical exercise.

OVERVIEW
2003 saw an unprecedented reduction in the number of injuries requiring leave for threedays or more –from 110 accidents reported in 2002 to 83. Even the figures for serious anddangerous occurrences have dropped considerably. The St. Louis Power Station recorded themost laudable performance, with only one accident during 2003.
This result has been achieved through an ambitious programme aimed at tackling the maincauses of workplace accidents and ill-health, and encouraging sectors that have the worsthealth and safety records to make significant improvements. Regular medical check-up orscreening, follow up of work-related illnesses, supply of appropriate and suitable tools andequipment, and changes in working methods have all contributed significantly towards thisimprovement.
In collaboration with the Welfare Section, regular attention has been given to recreationalactivities aimed at creating a good morale and reducing stress at work.
ERGONOMICS
The past years have shown how a number of accidents were caused as a result ofmishandling of objects, making wrong movements or even when alighting from transport.In far too many workplaces, ergonomics is still not considered an important health andsafety improvement tool.
The Health and Safety Section has increasingly been involved in regular talks and lectureshighlighting the various postures to be applied for different movements. However, the wayforward is to draw up an individual ergonomics plan to ensure that the identified hazardsare dealt with in the right way.
CONTRIBUTION OF TRADE UNIONS
The Trade Unions have played an important role in hazard identification. Cases of non-compliance with the safety rules and failure to use suitable tools and equipment by jobcontractors have been brought to the attention of Management. The Unions have alsopointed out certain housekeeping issues which could have resulted in ill-health. Theseinclude pigeon droppings in some of our power stations, the spread of asbestos dust on thefloor, noise pollution, and other hazards which Management is striving to eliminate.
ASBESTOS DISPOSAL
The CEB has waged a ceaseless battle for the replacement and disposal of asbestos. At Le ValPower Station, the asbestos roofing has been replaced by alternate asbestos-free irons sheetsand at Fort Victoria Power Station asbestos has been replaced by rock wool in the MirrleesEngine Room.
SAFETY AND HEALTH COMMITTEES
The main Safety and Health Committee together with the restructured Regional Health andSafety Committees contributed largely to a sound follow-up of the performance at all worklevels within the CEB. They also assisted Heads of Section in providing counselling on Safetyat Work and Safety Rules.

PerformanceProduction1. GENERAL
The overall status of energy generation mix in the current year has improved in comparisonwith the previous year. This was mainly due to the absence of load flow constraints on the66kV transmission lines now that the upgrading to 132kV has been carried out, and tovigilance in the operation of base load units at Fort George in order to improve its operationload factor, as well as an average increase in demand of 7.28%.
However, the contribution of energy from combustion turbines at Nicolay increased tosome 1.8% of total generation. This was due to a daily demand pattern associated withan atypical hydraulicity, particularly during the first quarter, and unscheduled stoppagesof base load units throughout the year. It must be noted that the peak demand for theyear reached 323.8 MW, an increase of 4.93% with respect to the previous year.
Unscheduled outages for the year have averaged 4.5% of maximum demand, animprovement of 1% with respect to the preceding year. Similarly, average scheduledoutages have been reduced to 10.5% from 15.4% during the previous year.
Regular maintenance of equipment has helped to ensure good performance in allpower stations. In addition, as part of the ongoing modernisation process, equipmentbased on new technology is gradually being introduced in our power stations.
Various control measures have also been taken to mitigate environmental problems, ademonstration of the CEB’s commitment to its social responsibilities.

Fort George Power StationTotal energy production was 750 GWh or 40.77% of total production. Average loadfactor for the year was 79% - substantially higher than the average load factor for 2002which was 65%.
All five units performed well and each clocked between 7 100 to 7 800 hours for theyear. Moreover during the last three months of the year under review, Unit 1 cumulatedover 90 days of continuous running, totalling some 2 208 hours. Overall engineavailability during this period was in the range of 97.7 to 99.5%. Scheduledmaintenance was carried out as planned on all five units, Unit 3 at the beginning of theyear and the remaining four units from June to November.
Units 1 and 2 were fitted with a new improved version of stuffing boxes and 3 cylinders ofUnit 2 were also fitted with new Tribo Pack kits, i.e. ceramic top piston rings and anti-polishing rings which will extend the time between overhaul by 2 – 3 times. Followingconclusive results obtained with the new upgraded components, full conversion of Unit 2has been envisaged during the scheduled maintenance of 2004. Thus, the enginedowntime for scheduled maintenance is expected to be significantly reduced as from 2005.
The TCS for Unit 2 was re-commissioned thus contributing to an increase in outputpower by an average of 400 kW during peak hours.
Other essential auxiliaries, operational and non-operational equipment weremaintained and refurbished, so as to ensure continuous non-stop operation.
Phase 2 of the SCADA Project which was initiated in 2002 was implemented on Units 1and 2. The conventional relay based control and supervisory system has now been fully

replaced by a PLC controlled computerised system designed and implemented in house.Operators can now follow operational parameters and operate the engine auxiliariesdirectly from the control room.
Saint Louis Power StationAll six units have operated satisfactorily during the year with an average operatinghours of 3 895 running hours per unit. Energy generated was 135.2 GWh representing7.35% of total generation. The plant operated throughout the year as semi-base loadand the corresponding plant load factor for the year was 26%.
It is noteworthy that Units 1 and 2, which were commissioned in October 1978, reachedtheir 25th year of operation on grid.
In November, the Board appointed Mott MacDonald to carry out a Project FeasibilityAssessment for the installation of 3 x 12 MW medium speed diesel engine at Saint LouisPower Station.
Nicolay Power StationThe three units have averaged 440 operating hours for the year, generating 32.3 GWh,representing 1.75% of total generation.
The replacement of the first stage bucket was successfully carried out under thesupervision of an Engineer from GE India during the maintenance of Unit No. 2.
The regrouping of all operating data of the units into a Central Control Room for efficientmonitoring has been successfully implemented.
Fort Victoria Power StationThe generating sets at the above station operated as semi-base load units during theyear under review and generated 75.2 GWh, representing 4.1% of the total energygenerated island wide.
The two MAN generating sets generated 51.5 GWh and have clocked 74 307 and 72119 hours of operation since commissioning. These units contributed to more than 68%of the total power station production with an average running hour of 3 200 hours. Itis to be noted that 70 000 hours maintenance were carried out on both units and newsupport rings have been fitted in Engine No. 11.

Mirrlees units have generated some 23.7 GWh with an average running hour of 1 048hours. There was a major breakdown of Unit No. 6 on 27th January. However, theengine was back on grid as from September, after grinding of the crankshaft by ABCEngineering Pte. Ltd., and complete rehabilitation of the unit. The 6 000 hoursmaintenance of Unit No. 7 was completed in May.
Owing to environmental constraints, the generating sets at Fort Victoria Power Stationare operated only between 8.00 hours and 21.00 hours daily. Whenever the wind isblowing inland, the Mirrlees units are removed from the grid.
To mitigate environmental problems, the following measures have been taken :
1. The erection of a 127 m long x 1.6 m wide x 10 m high sound attenuation wall alongthe eastside boundary of the power station has started since mid November.
2. A comprehensive vibration monitoring exercise was undertaken by Lloyd’s Registerof England.
3. An exhaust gas monitoring exercise has been carried out both by CEB and Universityof Mauritius.
4. Sound attenuators have been installed in the window openings of MANpower house.
5. Noise attenuation panels and door have been installed in front of the main entranceof MAN power house.
Further measures are contemplated to enable operation of the Power Station strictly in linewith prevailing environment legislation.

B HYDRO GENERATION
Hydro generation with a production of 117.7 GWh was more than satisfactory. Apartfrom Unit No. 4 at Tamarind Falls which was unavailable all throughout the year, allthe other units performed well. Routine maintenance of turbines and generators wascarried out as programmed and most of the capital projects were implemented.Unfortunately, some refurbishment works had to be postponed in view of eitherdelays in the supply of ordered parts or generating capacity shortage followingbreakdown of thermal plants. The main activities were as described below.
Champagne Power StationThe plant modernisation programme started in 2002 continued with thecommissioning of the SCADA System on Unit No. 2 in April.
The ageing butterfly valve servomotors of this unit were also replaced in Novemberby new ones supplied by EDF.
Ferney Power StationIn order to implement the project for the remote control of this plant fromChampagne, the 32-year old electromechanical governor of Unit 1 was successfullyreplaced by a digital regulator supplied by VATech of Switzerland. Work started on3 November and commissioning of the new governor by a VATech specialist tookplace on 13 December. It is noteworthy that this is the first digital regulator installedin our hydroplant.
Le Val Power StationIn compliance with new regulations calling for the removal of asbestos materials,the asbestos roofing of Le Val Power Station was replaced by iron sheetings. Workstarted at the end of September and was completed on 4 November. The buildingextension was also repainted.
Magenta Power StationThe 85-inch inlet valve which, following an inspection by a South African specialistin 2002 was found to be defective, was dismantled and sent to South Africa inOctober to undergo repairs.
C BASE LOAD I.P.P.’S
Power Stations of C.T.B.V., F.U.E.L. and C.E.L. generated 1 066 GWh or 33% of totalenergy generation.
C.T.B.V. Plant performed well with a total generation of 348 GWh and 23 GWh waspurchased at the lower rate corresponding to contractual surplus energy rate. Thetwo sets at F.U.E.L. suffered major technical operation setbacks with protractedunscheduled outages. As a result, offtake was short of the contractual target figureof 160 GWh by some 10 GWh.
The Plant at C.E.L. suffered from two weeks of unscheduled stoppage at thebeginning of the year but by the end of the year, the contractual energy offtakefigure of 110 GWh was just achieved.

Transmission and DistributionDISTRIBUTION
The year under review saw further initiatives being launched to strengthen the distributionside of the Utility business. The focus was on improving efficiency, customer service,introducing new technologies and simultaneously controlling costs in line with the long termstrategy to provide best service delivery to our customers at the least possible cost. Therewas significant progress in most of the planned projects and initiatives.
The major activities in the Distribution Department during the year and key operationalstatistics are highlighted below.
THE DISTRIBUTION AREAS
The Distribution Areas of North, Centre and South were created in 2002. During the currentyear several key activities were decentralised to speed up the decision making process. Mostcustomer needs are now tackled at Area level with uniform policy guidelines being set atthe Head Office. As a result, customers are no longer inconvenienced with trips to the HeadOffice. Probably the only exceptions are large industrial, commercial or residentialcustomers, who require special arrangements for electricity.
There was a long felt need for providing adequate IT enabled tools to improve customerservice and project execution. A successful bidder was identified for the proposed IT systemwhich would provide such tools. A set of Key Performance Indicators (KPIs) was drawn upto monitor the performance of the Distribution Areas. These KPIs are expected to beroutinely tracked on implementation of the IT Project.
PerformanceTransmission and Distributionfor the year ended 31 December 2003
SYSTEM PERFORMANCE
The general performance of the T&D network was very satisfactory. Furthermore, althoughCyclone Gerry came close to the island in February 03, there was no significant impact onour Transmission network. Interruptions in electricity supply arising from problems in theDistribution network were contained to a few hours and to certain localities in the Northand East only.
During the year, emphasis was on systematic and preventive maintenance. The followingtechnological weaknesses pertaining to system reliability and stability were identified andtackled:
• Distance Protection schemes on our Transmission Lines are being upgraded/introducedby installing ABB Type Rel 511 digital relays.
• Synchronising facilities have been installed and commissioned on the Saint Louis-Nicolay and Saint Louis–Rose Hill Transmission Lines to improve flexibility and reducerestoration time in the event of a major breakdown.
• The SCADA software has been improved to provide additional facilities for manualtelecontrol. Improvements have also been made in automated control to improvesystem stability under conditions of severe mismatch between demand andgeneration.
• Many of the old and aged 66 kV oil circuit breakers have been replaced with modernSF6 units.

Transmission and DistributionDEMAND, SALES & CUSTOMERS
System Demand & SalesThe maximum demand for the year was recorded at 323.8 MW in December. Thisrepresents an increase of 4.9 % over the previous year. Figure 1 shows the load distributionon a regional basis at the time of maximum demand.
The energy sold during the year totalled 1,607,046 MWh. Compared to the previous year’ssales of 1,491,669 MWh, the sales for the year under review have shown an overallincrease of 7.74 %. Figure 2 indicates the maximum demand experienced in the system forcorresponding months in previous years. It must be noted that in recent years there hasbeen relatively less seasonal fluctuation in demand for electricity thus reflecting increasingconstraints in having available adequate generating plant and T&D capacity.
Average load factor of the system during the year was 67.4 %, which compares well withelectricity utilities elsewhere with similar customer profiles. The average load duration isdepicted in Figure 3. The increasing divergence in rate of growth of demand vis-à-vis rateof growth of sales noticed in the previous year was reversed during the year under review.This is an encouraging trend.
Customer BaseAt the end of the year, the Board had 338,563 customers, an increase of 2.59 % of thecustomer base over the previous year.
Higher growth of sales when compared with growth in our customer base indicatesincreasing per capita consumption. This is a welcome departure from past trends.
Detailed Analysis of SalesFigure 4 indicates the growth in the number of customers of the Board over the last tenyears categorised by tariff. Figure 5 indicates total sales to each of the tariff categories forlast ten years. Figure 6 indicates average consumption of electricity by customer in eachtariff category.
Figure 7 indicates sales to various categories of customers and the rate of growth of salesin two consecutive years as compared to the preceding year. Sales to Domestic andCommercial customers grew significantly while the growth in sales to Industrialconsumption was maintained at the earlier level. Irrigation pump sets consumed less owingto the abundant rainfall in the island during the year. However, the most significant growthhas been in the “Other customers” category. This is mainly due to increased sales for streetlighting supplies (see “SYSTEM LOSSES”).
The trend of sales to different customer categories over the last ten years (Figure 8) indicatesthat increasingly more energy is likely to be sold to Commercial and Industrial customers ascompared to Domestic customers, as can be expected in a growing economy.
TRANSMISSION
To evacuate electricity effectively from the Generating Stations dispersed all over the islandand to improve electricity delivery to the nodal load centres represented by MajorSubstations, several transmission related infrastructural projects were either initiated orcompleted during the year. Brief details of the major projects are given below.
Maintenance of Transmission LinesA major thrust was given to preventive maintenance of Transmission lines which had beenidentified as a priority activity. The emphasis this year was on evaluating andreconditioning the lines erected more than 5 years ago. The lines were inspected to identify

potential weaknesses and maintenance work was carried out wherever necessary. Duringthe year, approximately 80% of such transmission lines have been thoroughly maintained.
132 kV Transmission ProjectThe newly constructed 132 kV Tower Lines functioned as expected without any problems.
Dumas SubstationThe protection concept regarding the lines going out of Dumas Substation was reviewed. Itwas decided that the short length lines from Nicolay, Fort George and Saint LouisSubstations would rely mainly on Current Differential protection. This represented a majordeparture from past practices. Trans Africa Projects were appointed as Consultants to helpimplement this new protection scheme and train CEB personnel. Tenders were issued forprocuring the relays and associated control panels.
All other works for the construction of this substation have progressed satisfactorily.The substation, with the new protection scheme, is expected to be commissioned inSeptember 2004.
Champagne – Union Vale – Combo 66 kV LineIn order to secure the supply to the South, a 66 kV line of about 35 km length is requiredbetween Champagne and Combo substations, via Union Vale switching station. The firstphase of the project consists of half of the 66 kV line from Champagne to Union Vale, wherethe existing 22 kV switching station would be upgraded to a 66/22 kV substation toimprove the reliability of supply to the South Eastern part of the island, includingthe Airport.
Construction of the line between Champagne and Union Vale was started at the end of2001 but had to be stopped to incorporate major changes requested by the AirportsAuthority. Construction resumed at the end of the year following receipt of the undergroundcables and this segment of the line is expected to be commissioned early next year.Construction for the Union Vale-Combo section is scheduled for completion by early 2005.
Henrietta – Black River 66 kV LineIn order to cope with the load growth in the South Western part of the island, resulting fromsignificant hotel development in the Le Morne region, a 66 kV line of some 25 km has tobe erected between Henrietta Substation and Le Morne to meet increased load demand.Pending construction in the medium term of a 66/22 kV substation at Le Morne, the linewill be operated at 22 kV.
Erection of the first 15 km of the line which started in September 2002 is now almostcompleted. Planning and design of the remaining section, is being reviewed to cater forresidential development along the original route.
Lightning ProtectionTo avoid damage from lightning strikes, lightning masts were erected at 3 more substationsduring the year and the earthing systems were improved at 2 substations. Erection of

PerformanceTransmission and Distributionlighting masts at Nicolay Substation has been postponed to synchronise with the diversionof outgoing lines from Nicolay Substation into Dumas Substation in order to minimizeinterruption of supply to our customers.
PRIMARY DISTRIBUTION
A large number of projects pertaining to the T&D network were either initiated orcompleted to better serve the increasing customer base.
Distribution System StudyMaterials were procured during the year with financing through a loan from the Arab Bankfor Economic Development in Africa (BADEA) for the prioritised projects from therecommendations contained in the Final Report on the Distribution System Study byexternal Consultants. The status of these projects is as furnished hereafter.
Ebene SubstationThe substation building was constructed and 22kV switchgear with all associated SCADAand telecontrol facilities installed in a relatively short time. This substation is intended tosupply the forthcoming Cybercity and to cater for future load growth of the area. Thesubstation is expected to be commissioned in early 2004.
Wooton SubstationPreliminary Civil design for housing the indoor switchgear in replacement of the existing22 kV outdoor equipment is in progress.
Performancefor the year ended 31 December 2003
Transmission and DistributionUnion Vale and Combo SubstationsDuring the year a new Power Purchase Agreement was signed with CTDS for a new PowerStation in the private sector at Union St Aubin. We expect to receive electricity from thisnew Power Station at Combo Substation. This will require robust and reliable evacuation ofpower locally as well as to other parts of the island.
A tender was launched at the end of the year for the construction of the indoor 66 kVsubstation at Union Vale to cater for load growth and to improve the reliability of supply tothe South Eastern part of the island, including the Airport. The substation is expected to becommissioned by early 2005. Similarly, design work has been completed to createprovision at Combo Substation to accept electricity from the new Power Station.
Reconstruction of St Louis 22 kV SubstationTo improve reliability of supply in Plaine Lauzun, Pailles, Coromandel and southern parts ofPort Louis, the existing aged 22 kV outdoor substation equipment is being replaced. A new22 kV indoor switchgear panel with SF6 breakers incorporating a most advanced PLC systemwas erected in a newly constructed substation room within our compound at St Louis.
Sottise SubstationInstallation of 66 kV equipment was completed in October 2003. The newly installed 22 kVswitchgear panel incorporating the same technology as mentioned above wascommissioned during the year. In both cases,the supplier of the new equipment trained ourpersonnel for commissioning and setting of the protection schemes. All outstanding worksat the substation are expected to be completed by third quarter of next year.
22 kV Cable between St Louis and Coromandel SubstationsWork started at the end of the year for the laying of a 3-km cable link between St Louis andCoromandel substations in order to secure the bulk supply point at Coromandel and to copewith the load growth resulting from the setting up of two spinning mills at La Tour Koenig.
Power Transformer CapacityAt the end of the year, the total power transformer installed capacity in the major substationswas 1,858 MVA. This represents a growth of 2.1 % over previous year. The growth in capacityis reflected in Figure 9.
SECONDARY DISTRIBUTION
While Transmission and Primary Distribution aims at building up adequate infrastructure tobring electricity to the local level, the Secondary Distribution network delivers thatelectricity to the bulk of the Board’s customers. Brief details of the major activities in thisrespect are given below.
Distribution Transformer CapacityAs far as the distribution substations are concerned, the total capacity has reached 1,095MVA. This represents a growth of 3.9 % over previous year. The growth in capacity isreflected in Figure 9.
Minor Development ProjectsContinuing the trend established in previous years, the CEB has been able to implement alarge number of Minor Development projects island-wide for the extension of its low-voltage network to supply new applicants’ premises. As usual, such projects were financedpartly by the CEB and partly from funds made available by the Government. 385 dwellingswere thus connected following the extension of 591 spans of low voltage network. Figure10 indicates the details of these projects in various localities of the island.

Summary of T&D networkDuring the year, the overhead network was extended by 119 km bringing the total lengthof overhead lines to 6,883 circuit km representing a growth of 1.8 %. This figure includesthe transmission system of 215 km of 66 kV and 132 kV overhead lines.
As for the underground network, 13 km of cables were installed during the year underreview, bringing the total underground network to 349 circuit km representing a growth of3.9 %. The underground system includes 10 km of 66 kV underground cables. Although theunderground system appears insignificant in relation to overhead, in real terms theunderground system serves key city centres of Port Louis, Curepipe, Quatre Bornes etc. andthus represents a vital component of the Board’s infrastructure. This year’s trend of theunderground network increasing at a faster pace than overhead is expected to continue infuture. Figure 11 shows the growth over previous years.
SYSTEM LOSSES
To keep system losses under control, an action plan was developed during the precedingyear to monitor the contributory factors and initiate action as and when necessary.
It was suspected that revenue was being lost through anomalies in the billing records forstreet lighting. Since this would normally affect system losses as well, a detailed pole bypole survey was carried out all over the island during the first quarter of the year to verifythe exact connected load for street lighting. Following the survey and subsequent meetingswith local authorities, the street lighting billing records were updated, with a consequentgrowth of sales for street lighting by a massive 26.4% from 21,841,304 kWh in year 2002to 27,610,698 kWh in year 2003.
Several such measures, identified in the action plan to control system losses, have beenfollowed up, with the result that system losses were not only kept in check but also showeda decline from 10.83% at end of year 2002 to 10.56% at the end of year 2003.

Corporate Planning & ResearchOVERVIEW
The Central Electricity Board aspires to become a modern utility operating on sound businessprinciples, delivering value and quality service to our customers and other stakeholders.
In Mauritius, we do not have an abundant supply of natural energy sources, we musttherefore plan carefully to ensure a reliable, sustainable and affordable electricity supply ata reasonable quality.
Three important areas of activity of the Department of Corporate Planning & Research duringthe year 2003 were the launching of the Corporate Plan 2003/2004, the launching of theIntegrated Electricity Plan 2003-2012, and generation capacity addition.
CORPORATE PLAN
The CEB officially launched its first Corporate Plan on 21 April 2003 at Clos St Louis,Domaine Les Pailles by the Minister of Public Utilities, Honourable Alan Ganoo. Throughthis Corporate Plan for the year 2003/2004, the CEB has rendered public its strategicdirection and has demonstrated that the organisation not only knows where it is going,but that it has indeed chartered a path for the future.
By making this Plan public, the CEB has stimulated the participation of each and everyemployee towards the achievement of organisational goals and has allowed thestakeholders to know and hold CEB accountable for the direction it has set.
The Corporate plan prepared by the Department of Corporate Planning & Research andpresented to the Government of Mauritius and the public embodies the overall businessstrategy of the CEB and sets well-defined priorities and objectives for the whole organisationagainst which achievements can be assessed during the lifetime of the Plan. The strategicdirection and goals of this Corporate Plan will live for many years. This Department intendsto publish Business plans which will outline the specific objectives and targets theorganisation has set for itself, how CEB expects to meet those targets, and progress inmeeting the targets. By outlining the company’s strategies and objectives, the Corporateplan will continue to provide a baseline for judging the company’s future performance.
INTEGRATED ELECTRICITY PLAN
Last year the CEB celebrated its 50th year of providing Mauritius with a reliable electricitysupply. However, there is a growing awareness of the future needs of Mauritius as regardsa stable electricity supply, in line with the economic development of the country.
This Department is particularly proud to have released the CEB long-term Integrated ElectricityPlan (IEP), the first of its kind in the history of the Board. It presents our current estimates ofthe evolution of demand for electricity in Mauritius and Rodrigues over the next decade, ourperspective on the options available to meet that demand, and a master plan for electricitygeneration, transmission, and distribution expansion and reinforcement. In the past, this typeof work had been done by outside consultants on an ad-hoc basis. The IEP, developed by thestaff of Corporate Planning & Research, is but one example of the changes and improvementscurrently taking place at the CEB.
The Plan was launched on the 27 November 2003 through a press conference at PetiteCannelle, Domaine Les Pailles. The “integrated” approach used to develop the IEPencompasses the simultaneous consideration of demand and supply. The CEB recognizesthat it is not possible to know the precise conditions that will determine electricity demandor the options to meet it in the future. Nevertheless the IEP presents a way forward that

Corporate Planning & Researchhinges on optimising the use of the existing power system, keeping electricity prices as lowas possible through least-cost capacity expansion, encouraging our customers to participatein energy efficiency and conservation, and with option for private sector participation.
GENERATION CAPACITY ADDITION
Following from the December 2002 Request for Proposals, the CEB reached an agreementwith a new IPP in 2003, Compagnie Thermique du Sud (CTDS), for the supply of electricityfrom a 30 MW coal-fired steam plant to be located next to the St. Aubin sugar factory.Before the agreement was reached this Department carried out an evaluation exercise and,entered into a predevelopment agreement and negotiations respectively with CTDS. TheCEB and CTDS finally signed a power purchase agreement on 15 October 2003. Under theterms of this agreement, CTDS will be fully operational no later than October 2005. ThisDepartment now considers this IPP to be a committed resource for planning purposes.
In July 2003, the Board decided to set up a technical committee, composed of staff fromProduction, T&D and Corporate Planning, to carry out a feasibility study for the addition ofthree units of 10-12 MW four stroke medium speed diesel engines at St. Louis PowerStation. Tender for the Environmental Impact Assessment (EIA) was issued in August 2003for the extension of St. Louis Power Station and after evaluation Mott Mc Donald wasappointed for the EIA in September 2003. The EIA report was received in October 2003 andwas submitted to the Ministry of Environment along with the necessary application toobtain an EIA License. Tender for technical assistance was issued in August 2003 and afterevaluation Mott Mc Donald was appointed for the work in November 2003.
Based on the forecast of probable demand and our supply of existing and committedgeneration resources, the next capacity resource additions are needed in 2006 to the tuneof 64 MW and St Louis can possibly supply 30-36 MW of the required capacity. A Request forProposals was issued in December 2003 for 60 MW to 70 MW of new generating capacityfired by bagasse and a complementary fuel in two phases, the first -30 MW to 40 MW- tobe developed in 2006, and the second, to be developed in the third quarter of 2007.
INFORMATION TECHNOLOGY & MANAGEMENT INFORMATIONSYSTEMS
In order to function as a modern businessenterprise, the CEB will have to meet theinformation needs of its customer service,operations, and strategic managementprocesses in the most efficient manner bydeveloping systems that will use moderninformation and communicationtechnologies. Thus the main objective of theInformation Technology and ManagementInformation System (IT/MIS) Department hasbeen to modernize and integrate the variousadministrative, commercial, financial andengineering tasks of different departmentsusing a common enterprise-wide informationtechnology platform.
The major projects achieved in the year 2003in line with this objective are:
• Structured Cabling in all officesThe data network infrastructure and thecabling systems of all the offices are nowcompletely installed to operate at 10/100 Mbps. Fibre optic data transmission technologyhas been used to interlink buildings within large CEB premises.
• Upgrading of the Wide Area Network to Frame RelayThe project to upgrade the existing X.25 network to a Frame Relay network has been carriedout. Most offices have already been upgraded. The use of digital leased lines is also envisaged.
• PC RolloutOwing to the inability of terminals to support modern graphic based applications, a PCrollout programme has been initiated and PCs are systematically being deployed topersonnel across the organization. Flat screen monitors (TFT) are being procured for allfront-end offices.
• Internet & Messaging FacilitiesInternet and messaging facilities to staff are also being provided along with the upgradingof the data network infrastructure.
• TrainingTraining has been initiated on office automation products with a view to improvingproductivity of users.
• New Enterprise Wide Information SystemThe CEB has recently embarked on the implementation of a new enterprise wideinformation system. The system will bring new business solutions that will enable the CEBto align its processes with best business practices. The business solutions will be based onSystem Application Products (SAP) and will address the following areas: Finance, HumanResources, Project Management, Materials Management, Billing and Invoicing, Procurementand Customer Care.

RodriguesENERGY GENERATION
The generating sets have run satisfactorily throughout the year under review. The totalnumber of hours of operation of the generating sets reached 23426 hours i.e an annualaverage of 7808 hours per generating set. The 3x1 MW MAN Holeby generating sets G7,G8 and G9 of Port Mathurin Power Station produced 18.3579 GWh, representing 75.2% ofthe total energy produced for the year 2003.
The remaining six Deutz MWM 500 KW engines, running on light fuel, were used for base loadand peak demand. With an average annual operation of 2826 hours per unit, these enginescontributed 6.039 GWh or 24.8% of the total production. Owing to limited generatingfacilities, a load management exercise was carried out on New Year’s festivities in order toavoid load shedding. All pumping stations and important customers were asked to switch ontheir standby generating sets during peak periods for Christmas and New Year’s Eve.
The maximum demand for power on 31 December 2003 was 4.75 MW representing anincrease of 8.0% over 2002.
NEW POWER STATION
The construction of a new Power Station at Pointe Monnier started on 27 November 2003.The contract was allocated to PAD & CO Ltd., on 13 November 2003. The site was taken overon 18 November 2003 and the power plant is expected to be operational in August 2004.
The Pointe Monnier Power Station will house 2x1.9 MW MAN Holeby Generating Setscapable of running on heavy fuel oil of 180 Cst. A 1.1 km underground pipeline will be laidbetween the existing Port Mathurin Power Station and Pointe Monnier Power Station for thetransfer of heavy fuel.
The power produced will be transmitted to the switchgear building at Port Mathurin via twounderground cables of 2x3x240 mm2.
RENEWABLE SOURCES OF ENERGY
To reduce our dependency on imported fossil fuel and to make proper use of environmentalfriendly renewable sources of energy in Rodrigues, the CEB decided to install a 3x60 kW windfarm at Trèfles. The tender was launched in May 2002 and the contract was awarded to VergnetS.A of France on 18 April 2003 for the design supply, transportation, installation, supervision,testing and commissioning of the 3x60 kW Type GEV 15/60 Wind Energy Convertors.
Civil work started on 23 June 2003 and was completed in July 2003. Erection of the 30 mtilted towers and nacelles started in November 2003. The first Wind Energy Convertor (WEC)was connected to the CEB grid on 2 December 2003. The remaining two WEC wereconnected to the CEB grid on 9 and 16 December 2003 respectively.

The power output from these Wind Energy Convertors will eventually represent 2% of thegrid demand. This will enable the island to save about 150 000 litres of fuel per year. Hadthe same amount of energy been produced by diesel generating sets, exhaust gasemissions would have amounted to 50 tons yearly.
CUSTOMER SERVICE
435 new customers were connected to the network. On the other hand 396 customers hadtheir accounts closed either on request or because they had left without notice or for nonpayment of their electricity bills, thereby bringing the total number of customers to 10 311,an increase of 0.81% over the previous year.
Table 2 shows the annual average consumption of electricity per category. There was anincrease of 2.68% and 16.53% respectively for domestic and commercial, whereas industrialconsumption decreased because of a period of drought when the pumping stations wereoperating at reduced rate.
A customer service centre was inaugurated on 10 March 2003 at Mont Lubin to serve CEBcustomers in the eastern and southern parts of the Island, who will thus save the time andmoney they used to spend on travelling.
DISCONNECTIONS FOR NON-PAYMENT OF ACCOUNTS
Table 3 shows disconnection work carried out during the year 2004 in spite of an intensiveradio campaign to invite customers to pay their bills in time.
TRANSMISSION AN DISTRIBUTION
The high tension network has been extended to supply REDCO of Le Chou (100 KVA), Airportof Rodrigues (250 KVA), AJMC workshop (250 KVA) at Le Marini Baie du Nord.
The low voltage network has been extended to supply Rodrigues Regional Assembly,Morcellements at Roche Bon Dieu, Port Sud Est and Citronelle.

GROWTH OF NETWORK
The 22 kV high tension network has been extended by 1.540 km consisting of 0.975 km ofbare conductor and 0.565 km of insulated twisted cable to reach 130.54 km. The lowtension network was increased by 7.9 km to reach a total of 322.9 km.
FAULTS
868 individual faults have been attended for period January to February 2003 and from Julyto December 2003.
The decrease in faults for year 2003 is due to the fact that from March to June 2003,reinstatement works were carried out following the passage of cyclone Kalundé causingdamages to 80% to our network.
