Međutim, od početka 1990-tih, potražnja je četverostruko porasla i dostigla 6.800 GWh. U isto vrijeme, proizvodnja struje opala je za polovinu, na nekih 4.000 GWh. Krive su male količine kiše i zastarjelost HE.
Since the early 1990s, however, demand has risen fourfold, reaching 6,800 GWh. At the same time, electricity output has shrunk by half, to around 4,000 GWh. Scant rainfall and the antiquated state of the HPPs are to blame.
