[en] The paper presents the results from the investigation about the scheme of connecting the two new 1000 MW units of the Belene NPP and the choice of scheme for own needs. A new connecting grid is envisioned for the northern part of the country and reinforcing of the connections in the southern part. The paper presents the results from the investigation about the scheme of connecting the two new 1000 MW units of the Belene NPP and the choice of scheme for own needs. A new connecting grid is envisioned for the northern part of the country and reinforcing of the connections in the southern part. The scheme for connection to the grid 110 kV is in compliance with the requirements of Atomelektroproekt. The equivalent grid impedance should be less than 10 Ohm. The equivalent impedance of the buss 100kV is calculated for the 6 chosen connections. The assessed investments are 500 bill. leva
