Impacts of the EBO V1 Decommissioning on ES SR
The EBO V1 decommissioning during 2006 - 2008 ⇒ loss of 2x440 MW in Križovany node (220 kV system)
880 MW loss

Primary Consequences of the EBO V1 Decommissioning
d d irect impact irect impact on on ES SR ES SR e e lectric lectric components components in in term of the dispatch
term of the dispatch control control
deficit of power output from EBO V1 unit (Križovany),
deficit of power in 220 kV nodes (Senica, Považská Bystrica, Bystričany),
influence on available volume of ancillary services for secondary control,
change of the ES SR configuration,
increase of the cross-border flows,
decrease of the 220 kV system operation

¾ substation Medzibrod ⇒ evaluation of its next usage at 220 kV voltage level,
¾ reinforcement of Lemešany node, resp. the whole Eastern Slovakia,
¾ technical lifetime of 220 kV lines V283, V274, V271, V275 (average age more than 40 years)

Solutions and Measures in TS SR (1)
re re c c onfigur onfigur ation ation a a nd nd re re construction construction of 220 kV system part to 400 kV voltage level due to loss of sources working to 220 kV system,
implementation of the direct direct transform transform ation ation 400/110 kV instead the indirect transformation 400/220/110 kV in relevant nodes,
power supplying of Kri Križ žovany ovany node locality from 400 kV system with preserving 220/110 kV transformer as
a coupling between the voltage levels for eventual self – consumption of EBO V1 and EBO A1 supplying,
power supplying Medzibrod Medzibrod node locality from 400 kV

Impacts of the EMO 3,4 Commissioning
New power source 2x500 MW soonest in the year 2012
¾ necessity of solving the power output of new units EMO 3,4 EMO 3,4 (2x500 MW)
(2x500 MW) to TS SR,
¾ necessity of solving the power output resulting from EMO 1,2EMO 1,2 power increase till the year 2008 (cca. 2x490 MW)
it is needed to solve and to review the power output to TS SR for EMO 1,2,3,4
EMO 1,2,3,4 as a whole aggregate
there is an assumption of power output to V.Ďúr substation, (specification after recieving complete details from investor)
necessity to process a new studystudy of new source effectof new source effect to TSto TS SRSR for existing EMO 1,2,3,4 power output
To take measure on sufficiency of current solution, resp. to adopt measures, while complete data needed for study are not yet available for SEPS,a.s.
¾ SEPS,a.s. consideres and planns its investment plan construction of new V.V. ĎúĎúr r –– GabčGabčííkovokovo 2x400kV 2x400kV line andline newnew GabčGabčíkovo íkovo substation
substation also concerning another contingencies and TS SR needs not only linked to EMO.
