* Newly brought under TenneT’s management

Disclaimer: The technical data for 2008 were compiled on the basis of TenneT’s own data and information supplied by the regional grid operators whose high-voltage grids (110 kV and higher) are managed by TenneT.

Explanatory notes

1)	The profit figure was significantly influenced by several provisional and final agreements concluded with the Dutch tax authorities concerning the fiscal opening balance sheet.
2)	Balance sheet total excluding assets not at free disposal, accounts receivable and accounts payable in connection with energy exchange transactions, and investment contributions received in advance.
3)	This concerns the HVDC connection from Eemshaven (Netherlands) to Feda (Norway). The total length of this cable link is 580 km; 290 is owned by TenneT and the other 290 km is owned by the Norwegian TSO Statnett.
4)	The difference in circuit lengths compared to previous annual reports is due to a more accurate measuring method.
5)	This concerns grids brought under TenneT's management in accordance with the Independent Grid Administration Act, which transferred responsibility for the management of all grids of 110 kV and higher to TenneT. The data excludes customer substations, the grids operated by Stedin, and the grids operated by Liander (which are subject to Cross Border Lease agreements).
6)	Including the new EDC380 converter station and its one-kilometre stretch of 380 kV line (EDC-EEM380).
7)	These failures did not always result in an interruption of the electricity supply.
8)	Twenty failures occurred in one day due to 'line galloping'.
9)	As a result of a failure in a terminal box at the Maasvlakte site.
10)	The failure of a surge diverter in the neutral point (150 kV) of a 380/150 kV interstage phase shifter at the 380 kV substation in Eindhoven resulted in an automatic switch-off of the 150 kV substations at Woensdrecht and Bergen op Zoom when lightning struck in the province of Zeeland (the energy that was not supplied amounted to 189 MWh).
11)	The increase in the absolute number of failures and interruptions is explained by the increase in the total circuit length and the greater number of substations managed by TenneT.
