Estonia price area hourly rates were rather volatile in June, fluctuating between 14 and 121 EUR, due to maintenance in several large production units (Olkiluoto 2 nuclear power plant and Mari-Pori plant in Finland, CCGT Lithuania) and restrictions of the connection between Kaliningrad and Lithuania, said Elering spokesman Ain Köster.
Estonian and Finnish electricity prices continued their steady convergence at the day-ahead market in June, being equal in 97.9 percent of the time when there was no capacity deficiency. Estonia’s price was 38 cents higher than that of Finland, but by 19.01 EUR lower compared to the EUR 54.9 average price of electricity in Latvia and Lithuania.
The entire NPS system’s price fell 4.24 percent in the previous month and the June system price was EUR 25.19 per megawatt-hour.
In June, the Latvian power system was able to cover 54 percent of its electricity consumption; in Lithuania the figure was 27 percent. Baltic states as a whole had 430 gigawatt-hours of short supply. 62 percent of the deficit had to be imported from third countries, and 38 percent from Finland.
Carbon dioxide emission quota prices in June were in the range of 5.14 to 5.81 euros per tonne, slightly more expensive than May prices (4.69 to 5.41).
Natural gas was imported in June for an average price of 30.01 euros per megawatt-hour to Estonia.
