Electricity supply mix differed from historic trend in May 2018 due to the accident on Enguri HPP
May 2018 due to the accident on Enguri HPP. The forecasted annual balance envisaged to meet increased consumption and exports by hydro generation growth. However, accident on Enguri’s powerhouse caused shutdown of the plant on May 24, 2018 before the full recovery on June 1, 2018. This accident caused unplanned deficit in the system, which was compensated by imports, thermal generation and abolished exports. Electricity imports reached 44MWh and came from Azerbaijan (69.0%) and Russia (30.4%). The thermal generation reached 76.2 GWh and accounted for 6.3% of total electricity supplied to the grid. This was contrary to the historic trend, when hydro generation was the major supplier to the grid, with no need for electricity imports and thermal generation.
