    – From 2010 to 2013, the national electricity consumption increased by 9.4% in Korea. In contrast, the electricity consumption of Seoul decreased by 1.6%

    – The percentage of Seoul electricity consumption out of the national total: 9.8% in 2013 from 10.9% in 2010.

    – Compared with 2010, Electric energy generated from renewable energy increased 2.1 times, reducing Seoul’s reliance on fossil fuels.

    – ‘One Less Nuclear Power Plant’ and other daily energy conservation campaigns proved to be effective as many households and companies supported the cause.

    – Despite the reduction of electricity consumption, the electricity charges have increased six times for the last four years, raising the charges by 13%.

    – There was no substantial difference for monthly average electricity charges for each household as a result of energy conservation efforts and increase of the household number.

    – In order to increase the power self-sufficiency ratio of Seoul to 20% by 2020, the SMG plans to expand its energy efficiency policies.


     

    From 2010 to 2013, the national electricity consumption increased by 9.4% in Korea. In contrast, the electricity consumption of Seoul decreased by 1.6% during the same period. The percentage of Seoul electricity consumption out of the national total also fell to 9.8% in 2013 from 10.9% in 2010.

    The monthly household electricity consumption in Seoul recorded 320kWh and 316kWh in 2010 and 2013 respectively, showing a 1.2 % decrease. There are approximately 3.59 million households in Seoul.

    In the meantime, electric energy generated from renewable energy such as photovoltaic power more than doubled, from 57GWh in 2010 to 120GWh in 2013.

    The Seoul metropolitan government released these statistics and reported that the electricity consumption of Seoul was reduced and electricity produced from renewable sources doubled. As a result, Seoul could reduce its reliance on fossil fuels and increase its power self-sufficiency ratio.

    The SMG analyzed that the ‘One Less Nuclear Power Plant’ campaign, which was launched in 2012, has been largely effective, as many companies, households and schools actively supports the initiative. As a result electricity consumption was cut back while renewable energy production increased.

    The ‘One Less Nuclear Power Plant’ initiative aims to address energy crisis and establish safe and sustainable energy production and conservation system by reducing energy demand and increasing renewable energy production.

    Given that housings and buildings account for 83% of total electricity consumption, the eco-mileage system, and various energy conservation campaign seemed to be paid off.

    In terms of energy demand, independent business owners and households accounted for 54% and 29% respectively, followed by industries, which took up 11% of the total electricity demand. On the other hand, the national energy demand showed different order, where industries consumed the most energy, taking up 56%, followed by independent business owners and households who accounted for 21% and 14% of the energy demand respectively. Other sources and schools accounted for 7% and 2% of the national energy demand.

    Despite the reduction of electricity consumption, Seoul citizens paid more for the electricity, as the electricity charges have increased six times. In 2013, the total electricity charges paid by Seoul citizens amounted to 5 trillion and 391 billion won, increased by 617 billion won or 12.9% from 2010.

    ※ The Electricity Charge Increase:

    2010, Aug: 3.5%

    2011, Aug: 4.9%

    2011, Dec: 4.5%

    2012, Aug: 4.9%

    2013, Jan: 4.0%

    2013, Nov: 5.4%

    In 2013, a household of Seoul paid average 39,300 won (for 316kWh) for its monthly electricity consumption, recording a slight increase from 38,300 won of 2010 (for 320kWh). This means every household paid about average 470,000 won of electricity charges a year.

    Despite electricity charges increase, the burden on each household was relatively lower, because households and companies reduced their electricity consumption through energy conservation and energy efficiency enhancement initiatives. The increase of household number of Seoul also appeared to have affected the result.

    In the meantime, the total electricity production of Seoul in 2013 was 1,946GWh. Considering the city consumed 46,555GWh of electricity in 2013, Seoul’s power self-sufficiency ratio is about 4.2 %.

    For the last four years, the amount of energy produced from thermal power has been largely stalled, while the energy from renewable sources more than doubled. In order to raise Seoul’s power self-sufficiency ratio, electricity production facilities of renewable energy should be enhanced consistently for a long-term.

    The electricity production capacity of Seoul is 683MW, which is about 0.8% of 87,170MW of the national capacity.

    Gwon Min, the director of Green Energy Department of the SMG said, “Our goal is to increase the power self-sufficiency ratio of Seoul to 20% by 2020. To this end, the SMG will enhance the electricity production capacity, and implement various energy policies, including regulation for building construction. For example, when a building that consumes a large amount of energy is constructed, the building should be equipped with its own energy-production facilities. Through these measures, the SMG will continue to make efforts to increase energy efficiency while reducing energy consumption.”
