Total net electricity generation higher, import lower than a year ago

In October 2023, total net electricity generation was 867 GWh. Compared to September, it decreased by 29%, and compared to October 2022 it increased by 64%. Generation in hydro power plants was 21% higher and in thermal power plants 95% higher. In October 2023 the nuclear power plant was working only for few days.

In line with the higher production in thermal power plants, fuel consumption also increased. Total fuel consumption was 82% higher than a year ago.

962 GWh of electricity was imported and 776 GWh was exported. Compared to the same month last year, import decreased by 21% and export increased by 18%.

More electricity consumed than in the previous month

In October, households consumed 247 GWh and business entities 589 GWh of electricity. Accommodation and food service activities consumed 30 GWh. Ljubljana was the only municipality with more than 10% of electricity consumed within accommodation and food service activities, namely 15.9%.

Energy supply up at the monthly and down at the annual level

Compared to September, the supply of energy commodities in general went up with exception of Kerosene Jet Fuel supply fall with 24% and Transport Diesel Oil supply fall with 19%. It increased by 33% with LPG, 30% with Hard Coal, 28% with Lignite and Brown Coal, 27% with Natural Gas, 17% with Other Petroleum Products, 15% with Heating and Other Gasoil and 14% with Coke Oven Coke.

Compared to October 2022, the supply of energy commodities decreased as 47% with Hard Coal, 30% with Transport Diesel Oil, 21% with Other Petroleum Products, 15% with LPG and 6% with Heating and Other Gasoil.

The share of energy from renewable sources in gross final energy consumption decreased below 23%

Last year the share of energy from renewable sources (RES) in gross final energy consumption in Slovenia was 22.94%, 1.70 percentage points lower than in 2021.

In the electricity sector it increased by 2.03 percentage points to 37.01%, mainly because of the large increase in electricity generation from solar (by 42.48%).

Compared to 2021, the share of RES in gross final energy consumption decreased the most in the transport sector, namely by 2.81 percentage points to 7.83%. The decrease was directly influenced by the 23.4% lower consumption of biofuels in transport, while the consumption of all fuels in transport increased by 8.63%.

Also in the heating and cooling sector, the share of RES in gross final energy consumption decreased compared to 2021, namely by 1.23 percentage points to 33.99%. In this sector, there were several impacts on the consumption of renewable sources. Wood fuels for household heating usually contribute the most to the share of RES in gross final consumption. Due to the mild winter, the consumption of all heating fuels in households decreased by 13.79% compared to 2021. At the same time, due to the regulated, lower price of extra light heating oil and disruptions in the market in the supply of wood fuels (wood, chips, pellets), there was a 20,53% decrease in the consumption of wood fuels for heating and a 11.77% increase in the consumption of extra light heating oil.
