In August, gas use fell for the second consecutive month in the industrial sector and continued to decline in the power generation sector, and accordingly, the total gas use decreased by 4.2% yoy.

8. Electricity

Electricity use increased by 2.5% year-on-year in August, led by the industrial and commercial sectors, while it declined in the residential sector.

9. Nuclear

The total nuclear generation posted a year-on-year growth of 27.6% in August, as its capacity factor increased partly due to a drop in the number of reactors that were subject to the planned preventive maintenance.

10. Heat and Renewable energy

Heat energy use increased in all sectors, posting a year-on-year growth of 15.0% in August.

Renewable & other energy use maintained the upward trend, posting a year-on-year growth of 12.2% in August, and the power generation sector led the growth.

11. Industry

Industrial energy use went down by 1.9% yoy in August, with the petrochemical and primary metals sectors leading the downward slide, while the fabricated metals sector consumed more energy.

12. Transport

Transport energy use posted a year-on-year growth of 18.9% in August, as energy use grew in all sub-sectors except the rail sector.

13. Buildings

Energy use in buildings went up by 3.5% year-on-year in August, led by the commercial sector, partly because the service industry performed well.

14. Power Generation

The total power generation and fuel input rose by 4.2% and 5.2% respectively in August on a year-on-year basis as a result of increased electricity consumption.

Statistics on Energy Production Facilities and Statistics on Energy Consumption

1. The Economy and the Industry

The mining & manufacturing production index posted a year-on-year growth of 1.5% in July, led by the semiconductor and automobile sectors, although the production declined in the iron & steel and basic chemical sectors.

The service production index went up by 4.6% year-on-year (in July), as production increased, especially in the food & accommodation sectors.

2. Energy Prices[1]

Global oil price declined in July partly amid concerns on the global economic recession, even though geopolitical risks surrounding Russia persisted.

Gasoline and diesel prices fell by 2.6% and 0.2% respectively in July from the previous month, owing to the global price decline and an additional fuel tax cut.

The relative price of propane in terms of city gas for industrial customers (propane/city gas) dropped by 12.2% to 1.35 in July from the previous month.

City gas rates increased in all end-use sectors in July, as the increase in LNG import price was reflected in raw material costs.

Electric rates increased in all end-use sectors by around 4% in July, as the fuel cost pass-through adjustment rate was revised upward in 3Q.

3. Energy Supply

The total energy import volume was down 1.6% year-on-year in July, as the import volume of all energy resources declined except crude oil.

4. Energy Consumption

Total Primary Energy Supply (TPES) increased by 2.1% year-on-year in July, led by growing use of nuclear and renewable energy, while coal and petroleum use decreased.

Total Final Consumption posted a year-on-year growth of 1.7% in July, led by the building and transport sectors, although the industrial energy use slightly declined.

5. Coal

Coal use declined by 4.1% year-on-year in July, as it started to decline in the industrial sector and continued to decline in the power generation sector.

6. Petroleum

Petroleum use increased by 2.0% year-on-year in July, with the transport and industrial sectors driving the growth.

7. Gas

Gas use decreased by 4.9% year-on-year in July, as it continued to decline in the power generation sector and started to decline in the industrial sector.

8. Electricity

Electricity use surged in the building sector and grew quite fast in the industrial sector, and overall, the total electricity use grew by 5.6% year-on-year in July.

9. Nuclear

The total nuclear generation jumped 24.8% year-on-year in July, as its capacity factor increased due to a drop in the number of reactors that were subject to the planned preventive maintenance.

10. Heat and Renewable energy

Heat energy use grew by 5.0% year-on-year in July, as it increased in all end-use sectors.

Renewable & other energy use posted a year-on-year growth of 11.8% in July, and it grew more strongly in the power generation and transport sectors.

11. Industry

Industrial energy use slid by 0.4% year-on-year in July, with the primary metals sector leading the downward trend, although it increased in the petrochemical and fabricated metals sectors.

12. Transport

Transport energy use increased by 4.9% year-on-year in July, as it increased in all sub-sectors including the road transport and aviation sectors.

13. Buildings

Energy use in buildings grew by 7.6% year-on-year in July, as it grew in the residential, commercial and public sectors all together.

14. Power Generation

The total power generation and fuel input grew by 1.6% and 4.2% respectively in July on a year-on-year basis, as a result of growing electricity consumption.
