One Less Nuclear Power Plant 2

- Seoul Sustainable Energy Action Plan

The “One Less Nuclear Power Plant 2 – Seoul Sustainable Energy Action Plan” is Seoul Metropolitan Government’s second phase of its regional energy policy, which launched in April, 2012. Seoul’s energy policy of producing, saving, and increasing efficiency through citizen participation is equivalent to “housekeeping,” and “energy sharing,” and will reinvigorate the lives of Seoul citizens, future generations, and residents of other regions.





While maintaining the previous friendly and cute calligraphic style, the continuity of the two phases(of the energy policy) will be promoted. Also, the rounded curve without edges or angles will be highlighted, and messages will be expressed through signs and symbols, opening up the possibility of combining and applying diverse signs and symbols.

Key Messages

The goal of the “One Less Nuclear Power Plant 2 – Seoul Sustainable Energy Action Plan” is to reach 20% of the electricity self-reliance rate by 2020. This initiative is expected to reduce ten million tons of greenhouse gases and four million TOE(Ton of Oil Equivalent). In the first phase, the foundation was established for new and renewable energy production and energy culture based on citizen engagement, and in the second phase, the three core values – energy self-reliance, energy sharing, and energy participation – will be realized through institutional improvements and social structure innovations. Also, eighty-eight unit projects of the four policy categories will be implemented in order to create a virtuous cycle based on a sustainable energy eco-system, where citizens themselves produce and consume energy efficiently.

Three Core Values


Four Energy Goals


Seoul will decentralize the energy production by converting ten million Seoul citizens from a consumer to a producer. Key project areas include installation of mini PV panels for apartment balconies, construction of solar power plants with citizen funds, and implementation of a decentralized energy generation plan through new and renewable energy sources. Also, new buildings will be required to generate energy, amounting up to 20% of their consumption by new and renewable sources and decentralized energy generation system.


As a means to create a low-consumption social structure where energy is produced and used efficiently, a customized energy diagnosis program for buildings, environmental impact assessment, disclosure of the energy information of buildings, LED substitution, and the Eco-Mileage Program, an energy saving program to engage citizens, will be carried out.


By fostering innovations in the energy industry, more sustainable jobs will be created. IT electricity technologies favorable to big cities, such as BEMS(Building Energy Management System), smart grid, etc., will be supported, and regional-based energy services industry will be nurtured. Also, social enterprises and cooperatives in the area of green energy will be cultivated while creating more jobs through energy hub centers in local communities.


In order to address the welfare issues of the energy underprivileged people at an institutional and communal level, the basic rights of citizens in terms of energy will be guaranteed along with the expansion of energy self-reliant villages.

One Less Nuclear Power Plant

One Less Nuclear Power Plant is Seoul Metropolitan Government’s energy policy for future generations. In order to actively address the global energy crisis and climate change, it aims to raise the Seoul’s power self-sufficiency rate from 3% in 2011 to 20% in 2020 by saving energy with citizens and producing renewable energy through photovoltaic power plants, etc., in addition to saving and replacing two million TOE of energy produced by nuclear power plants by 2014. In June 2014, 2.04 million TOE was gained six months earlier than initially scheduled.


Ongoing Projects

In regards to One Less Nuclear Power Plant, there are three core areas of energy production, efficiency, and saving and six policy areas that include expansion of renewable energy production, efficient use of energy in buildings, establishment of eco-friendly and high-efficiency transportation systems, and the creation of green jobs and a compact city consuming less energy. Seventy one projects in each area will be carried out.

Significant Accomplishments

Two years after implementing the One Less Nuclear Power Plant initiative the energy savings (910,000 TOE) followed by efficiency (870,000 TOE) and production (260,000 TOE), which outpaced the target goals by two-fold, showed remarkable results. Consequently, in 2013, when a noticeable performance was first seen, the average electricity use rate nationwide increased 1.76% but for Seoul it declined some 1.4%. The use of electricity, gas, and oil all showed a downward trend.


Energy Production

In terms of energy production, including 3,756 solar power plants (69MW) that were established with KRW 63.5 billion of private capital, the Seoul Metropolitan Government (SMG) has attracted private capital of KRW 400 billion in total, successfully constructing the infrastructure capable of producing a variety of clean renewable energy, e.g., to provide electricity to 300,000 households.

Energy Efficiency

Some 6.79 million LED lights, which are brighter, last longer and more energy efficient, were offered through low-interest loans and first-investment & after-cost recovery from 2012 to 2014. Particularly, in collaboration with the Korea Finance Corporation, 430,000 lights in 243 subway stations in Seoul were all replaced with LED, without SMG’s financial assistance.


Energy Savings

The number of members of Eco-mileage, an energy saving program to engage citizens, increased dramatically to 1.7 million (480,000 members from institutions and households) as of February 2012, promoting a culture of saving energy at home and work. In 2013, Seoul took second place in the U.N. Public Service Awards in the category of “Fostering Participation in Public Policy Decision Making through Innovative Mechanisms.”




“Healing City, Healing Earth” is a concept that represents a brighter city that is created by putting sound thought and behavior together, and a healthier earth is created based on each healthy city. The BI of One Less Nuclear Power Plant was selected through a public contest and completed by talent donation from Ahn Dong-min, CEO of Intergram Graphics.

Energy saved together leads to one less nuclear power plant



The character’s name of One Less Nuclear Power Plant is Donggeuri, a solar angel. It has the face of a Seoul citizen, who saves as well as creates energy.
