In 2013, KOSTT continued itspositive business perform-ance, characterized by nu-merous developments, bothin terms of development aswell as regional integration.
In terms of transmissioninfra-structure development, KOSTThas already shifted to a com-pletely financially self-sustain-able mode, and in 2013signed a second loan withthe German developmentbank KfW, to ensure financ-ing of network projects.Moreover, discussions havebeen initiated with the Euro-pean Bank for Reconstructionand Development (EBRD) forthe financing of investmentprojects in the coming pe-riod.
On the other hand, KOSTThas continued its commitmentto seek integration in re-gional mechanisms andprocesses, such as the com-
mitment for the establishmentof the Coordinated AuctionOffice in South-East Europe,and developing infrastructureto meet the criteria for mem-bership in ENTSO-E.
One of the projects worthhighlighting is the 400 kV in-terconnection line betweenthe Republic of Kosovo andAlbania; a project of high im-portance for both countries,and the Frequency –PowerRegulation project, which willboth allow for a higher ex-change of energy with the Re-public of Albania and theregion, and optimizes thesystem operation.
KOSTT Board of Directors, inorder to fulfill its duties, hascontinuously monitored thedevelopments in the com-pany by comparing themwith the objectives set out inthe Business Plan and otherdocuments. Significant contri-
butions were also providedby functional committees ofthe Board of Directors, whichhave closely followed the de-velopments in certain areasand provided recommenda-tions and support to theseprocesses.
In conclusion, the financialaspect of the business hasshown satisfactory results in2013, and it is worth notingthat KOSTT has declared andpaid dividends to the share-holder in the amount of 3 mil-lion euros.
The Board of Directors re-mains committed and stronglybelieve that the success ofKOSTT will will be presentalso in 2014 and expressesits gratitude to all employeesand management of KOSTTj.s.c.

In 2013, KOSTT continued its journey in fur-ther consolidation of the transmission infra-structure, and its engagement in developinga platform to enable integration with regionaland European mechanisms, thereby imple-menting projects and initiatives in ensuringsecurity of supply and quality services for thetransmission system users.
In the past, numerous activities have been un-dertaken in completing ongoing projects,and to begin the implementation of the 400kV Interconnection Line Kosovo-Albania proj-ect, and the Frequency-Load Regulation proj-ect, both to contribute sensibly in optimizingthe systems and economic development ofboth countries. Both the projects were con-tracted for implementation in 2013.
A successful implementation of capital proj-ects shall facilitate the fulfilment of key objec-tives set forth by the KOSTT, in full compliance
with technical requirements deriving from theENTSO-E acts.
Operation Agreements with Serbia andMacedonia were negotiated in 2013, andthey are to be signed in the first quarter of2014, thereby completing interconnectionagreements with all neighbouring countries(agreements with Albania and Montenegrowere already signed earlier). The Kosovo-Ser-bia Energy Agreement signed by the PrimeMinisters of Kosovo and Serbia has pro-moted the KOSTT as an internationally recog-nized operator, as regulated by theOperation Agreement.
The Transmission System Operation Perform-ance has been proven good in 2013, withcontinued improvement in comparison to thepast year. Lines and sub-stations were main-tained as per plan, check-ups/inspections ofsub-stations and lines were completed, and

regular overhauls were made in SS fields,and also new SSs were commissioned intofunction, thereby including commissioningand testing of relay protections, and the im-plementation of many other important proj-ects.
Operational functions in monitoring, andspecifically operating the real-time systemhave advanced, while the Telecom and Com-mercial Metering Infrastructure SystemSCADA\EMS already offers highly ad-vanced possibilities for high-security opera-tions.
In 2013, KOSTT has worked in developinga strategy for entry into telecommunicationsmarket, thereby offering the surplus opticalfibre capacities. In this regard, the KOSTTBoard of Directors rendered a decision initi-ating activities for application for authoriza-tion/license for Telecommunications Market
Service operator, an application approvedby the Electronic and Postal Telecommunica-tions Regulatory Authority (ARKEP) of Kosovo.
For the seventh time in a row, the year of2012 marked the seventh report of the exter-nal auditor without any qualification, whichis a clear reflection of professional work andthe commitment of KOSTT in implementingthe highest standards in work processes andsuccessful completion of and utilization of allresources available to KOSTT.
The focus of KOSTT in the coming periodshall be on ensuring commercial sustainabil-ity and capacity development of KOSTT em-ployees, the driving engine of thedevelopment of the company and the coun-try.

LOssEs iN TRANsmissiON NETWORk Since its establishment in 2006, KOSST has steadily invested in transmission network devel-opment and asset maintenance, factors which, among others, have contributed to halve theelectricity losses of the network. While in 2006 losses were 3.78%, in 2013 they were at1.30%. Since the establishment of KOSTT in 2006, the measures implemented for the trans-mission network development, operation with optimal methods and effective network main-tenance, have all increased the performance of the transmission system, and reducedtechnical losses in the system. Losses in 2013 have recorded a slight increase, by 1.8 GWh,while there is a reduction in percentage compared to the previous year. This comes as aresult of the government’s modification of transmission boundaries with the distributionthrough its Decision No. 10/29. However, losses are back under the limit allowed by theERO, at 0.78%. The percentage of losses is calculated in relation to the whole energy whichenters the transmission network, data which are presented in Fig.3.

Fig 8 Number of assets according to the voltage level for 2013
Changes in the number of fields shown in Figure 3 at the 220 kV level from 2012 to 2013occurred from the commissioning of AT3 in SS Prizren 2 and the inclusion of generator fieldsin SS Kosovo A.
Changes in the number of fields at the 110 kV level were done with investments carried outin the network, including SS Gjilan 5 with 5 fields, SS Prishtina 7 with 2, changes in thescheme in SS Gjakova 1 from 3 fields to 7, the addition of 2 fields in SS Lipjan and 2 fieldsin SS Prizren 2.
On the 35kV and 10kV side, only fields in the secondary side of transformers are included.Figures 10 and 11 show the implementation of the plan for the maintenance of power lines(OHL) and Substations (SS). It is clear from the figures that activities which do not require dis-connection are realized completely, whereas repairs and revisions of fields in some caseshave not been implemented due to the inability to disconnect.

Figure 13 shows a comparison of interventions in OHL from 2009 to 2013. This figure indi-cates that the number of emergency interventions has declined from year to year. 400kVpower lines have had no need for intervention during the past two years. 220kV and 110kVlines saw a decline in the need for interventions. The main problems faced by KOSTT in2013 in terms of power lines were the downtimes in towers OHL 1806 and OHL 2298.
Even transitional faults in LPs and transformers (TR) during the last three years have mainlydecreased as a result of ongoing maintenance and investment.

Figure 17 shows the availability of transformers at all voltage levels. Autotransformers400/220 kV were available 88.31%. AT3 in SS Kosovo B was out of operation for most ofthe year due to the need for more detailed maintenance, reducing the total availability ofthese autotransformers. Transformers of 110/35/10kV level had an availability of 80.77%as a result of projects that have been developed as well as the activation of two transformersat SS Palaj as a result of the energy balance.
ENViRONmENTAL POLiciEs ANd kOsTT ENViRONmENT imPAcT One of the KOSTT objectives is the responsibility to ensure environmental protection fromoperational activities of KOSTT. To support a sustainable development, in 2013 KOSST hastaken necessary actions towards the advancement of this objective. The current goal is cer-tification with international standards ISO 14001:2004 for the Environmental ManagementSystem (EMS). For this purpose, relevant documentation is under development.
The following supporting documents were drafted in 2013:
• Project for the Recycling of KOSTT waste (initially paper, plastic, glass). Coop-eration with municipal level.
• Project for the management and identification of PCBs and PCTs in oils of trans-formers in KOSTT power facilities.
• Assessment of oils in SS 110 kV transformers, including sampling, testing ofsamples, environmental aspects and test reporting.
• Establishment and application of the procedure for the removal of eternit fromthe roof of the central building of KOSTT (which includes asbestos).

TRANsmissiON iNFRAsTRUcTURE dEVELOPmENT dURiNG2013, ANd RELEVANT iNVEsTmENTs The development of the electricity sector in Kosovo is based on the national strategy on en-ergy and the strategic objectives of the European Union, part of which Kosovo strives to be-come. Transmission system development, as one of the main pillars of Kosovo's electricitysystem, is supported by the 10-year development and investment plan, which sets a list ofprojects and dynamics of their implementation, by priority.
Appropriate transmission system planning and development, in compliance with technicalrequirements deriving from ENTSO-E, is crucial for the development of Kosovo's electricitysystem. The main objectives of transmission system planning and development are as follows:
• National security of long-term electricity supply through the transmission system; • Promotion of energy market integration at national and regional level, as well as
enhancement of competition and transparency. • Promotion of the development of new conventional and renewable energy genera-
tion capacities; • The country's economic development.
Adequate transmission system development and planning is related with the determinationof optimal configuration of the grid and ancillary systems, always in correlation with in-creased consumption and generation planning for the planning period, so as to fulfill con-sumer supply demand in a safe and economically feasible manner. The transmission systemis considered a rather complex and dynamic system, with ever increasing and variable elec-tricity demand, and ever changing generation, and interconnection flows at national and re-gional level. In order to accommodate such changes, the transmission grid requiresappropriate reinforcements in, which in the long-term provide for an enhanced performanceand operational reliability of the transmission system.
As a continuation of core activities in the enhancement of transmission system capacities, re-liability and safety, conducted by KOSTT during the period 2009-2012, 2013 also showeda high dynamic in the implementation of projects initiated in 2011-2012, and other projectsas envisaged in the Transmission Development Plan (2012-2022), approved by ERO.
Transmission System infrastructure planning and development is focused on four differentproject development categories:
• Enhancement of transmission grid capacities; • Revitalization of high voltage substations and equipment; • Grid operation support systems (SCADA/EMS, metering groups, ancillary services,
modernization of relay protection, etc.)• Load and generation support (transmission grid connection applications).
Investments implemented in 2013 reach an amount of 8 million euro, mostly funded throughKOSTT's own budget.
dEVELOPmENT OF TRANsmissiON sysTEmcAPAciTiEs dURiNG 2013 Infrastructure development project implementation in 2013 was characterized with a highdynamic of activities, without posing any threats to the reliability of the transmission system,owing to the implementation of key projects finalized between 2009 and 2012, such asPackage Project 3, Package Project Ferizaj 2, the third 150 MVA automatic transformer inSS Kosova A, SS Prishtina 4 and SS Prizreni 2, etc.
By the end of 2013, transmission grid capacities for internal consumption were increasedby 1.35% in comparison to the beginning of 2012, whereas criteria related to N-1 remainedunchanged. However, in 2013, a radial supply problem for SS Lipjan, now supplied throughthree 110kV lines, is now eliminated. During peak load system operation, unplanned outageof the sole automatic transformer of SS Peja 3 400/110 kV is considered critical as it causesoverload of a number of 110kV lines and critical voltage decreases in a number of 110kVnods in the system. This problem will be overcome after the installation of a second 300MVA transformer in SS Peja 3, which is expected to become operational in 2016.
Establishment of strong 400kV nods in SS Peja 3 and SS Ferizaj 2, and construction of 110kVlines and their reinforcement, provided for system operation within the frequencies allowedby the Grid Code during 2013 (in normal transmission system operation conditions in peakload).

iNVEsTmENTs imPLEmENTEd dURiNG 2013 2013 is characterized as a year in which capital investments were implemented fromKOSTT's own budget, whereas donor-funded investments from the investment plan are stillnot under way.
In 2013, KOSTT invested in a number of projects continued from 2011/2012:
1. Package Project SCADA/EMS and Telecom: LOT-1:SCADA/EMS;2. Package Project SCADA/EMS and Telecom: LOT-2: Telecom;3. Replacement of the conductor, isolators and connection equipment in OHL 125/2
and 125/3;4. Connections in SS Lipjan, in OHL LP 212 ( Kosova A - Ferizaj 2);5. Reallocation of the 110kV line, no. 1806 SS Gjakova 1 - Gjakova 2, and Reha-
bilitation of HV Equipment in SS Gjakova 1; 6. Rehabilitation of high voltage 110kV equipment in SS Gjilani 1 and SS Ferizaji 1; 7. Installation of two new fields in lines 110kV in SS Prizreni 2;
Implementation of projects is always accompanied by various hazards mostly related to theinability to access relevant equipment, as it was the case with the line OHL 125/3 - line toVallaç. Due to the political situation in the north of Kosovo, this project could not be imple-mented. Delays in project implementation, especially those related to the construction of lines,are also caused by land expropriation procedures.

According to the Law on Electricity and Market Operator License (MO), KOSTT is mandatedto develop Market Rules (MR). Upon approval of the Kosovo Electricity Market Design inMarch 2013, the Market Operator modified Market Rules, in order to provide transparentand non-discriminatory conditions for electricity trading between stakeholders, and in De-cember 2013 the said rules were approved by ERO. They stipulate the manner of wholesaleelectricity trading between parties. According to Market Rules, electricity market shall be abilateral market, based on long-term bilateral contracts between generators, suppliers andcross-boundary traders, and day-ahead electricity market nomination contracts. Parties willbe responsible for any electricity imbalances caused. Rules also cover trading of cross-bound-ary transmission capacities and allocation of physical transmission rights of parties.
Electricity generation, consumption and cross-boundary flows in 2013, as metered in theboundaries of Kosovo's trading zone are presented in Figure 20..

kOsTT cOOPERATiON ANd iNTEGRATiON iN REGiONAL AssO-ciATiONs ANd mEchANisms One of KOSTT's most important objectives of the recent years was regional integration. De-spite continuous engagements in this regard, KOSTT continues to face numerous obstaclesin relation to integration in regional mechanisms. Upon execution of the Agreement on Energybetween Kosovo and Serbia in September 2013, KOSTT and EMS have commenced nego-tiations on an operational agreement, as two regulatory zones, which will open the path toKOSTT's integration in all regional mechanisms. It is expected for said agreement to besigned during 2014.
In 2013, KOSTT continues to remain:
1. An observer in RG SEE1
a. An observer in SG CMMI22. A founding member of the Project Company for establishment of CAO3
CAO Project Team Company has successfully concluded its work and established all prereq-uisites for the establishment of the Interconnection Transmission Capacity Allocation Office(SEE CAO), which will start its work January 2014. Regarding the KOSTT-EMS dispute,KOSTT's complaint against Serbia, as a signatory party of the treaty, was submitted in theEnergy Community Secretariat (registered as Case 3/8), in relation to the Serbia's failure(breach) to fulfill obligations deriving from the Energy Community Treaty, respectively articles3 and 6 of Regulation No. 1228/2003 pertaining to compensation of electricity transitsand allocations of transmission interconnection capacities, despite the ECS conclusion issuedon the case, remains as of yet unresolved.
