Seoul 1 GWp ‘Solar City’ Highlighted at Mayors Forum

The 2019 Mayors Forum (part of IREC held in Seoul in October) featured Seoul’s 1 GWp Solar City Initiative. FREE helped the City to design this ambitious program as part of the FREE-Seoul Metropolitan Government (SMG) Memorandum of Understanding (MOU). Dr. Byrne delivered the keynote at the Forum, which drew 37 mayors from 25 countries. Mayor Park Won Soon chaired the Forum.

Seoul Metropolitan Government (SMG) plans to invest $1.5 billion in their strategy to deploy 1 gigawatt (GWp) of solar energy by 2022. As part of the MOU, FREE has provided the modeling and technical assessment of the city’s rooftop potential as hosts of a distributed solar power plant. FREE also calculated the economics of the project and used a financing structure it has developed for city-scale investment in such a project. (FREE has published results of it modeling and financing approach for 5 cities in addition to Seoul: New York City, London, Munich, Amsterdam, and Tokyo.)

In November 2017, Seoul Metropolitan Government (SMG) declared its intention to deploy 1 gigawatt of rooftop solar as part of its “Solar City Seoul” master plan. Over the next five years, Seoul city government plans to invest $1.5 billion to make the project a reality. This is a significant step forward in the future of Seoul’s sustainability contribution and follows in the wake of the very successful first stages of the city’s One Less Nuclear Power Plant (OLNPP) initiative. 1 Under initiatives like the OLNPP, Seoul focused heavily on promoting energy conservation and efficiency improvement. With this new Solar City Seoul plan, the city is ramping up investment in energy production as well. FREE applauds this direction chartered by the Mayor of Seoul, Mr. Park Won-soon.

FREE has been actively advising the city for five years on the prospects of becoming a “solar city.” As part of the Seoul International Energy Advisory Council (SIEAC), Dr. John Byrne has described to city officials the potential of rooftop solar across the 10-million people strong city. FREE has also published several refereed articles analyzing the emergent role of the solar city concept coupled with new priorities, such as policy effectiveness, solar financing support, and market mechanisms available to Seoul to explore this potential in detail. 2 For example, research we have conducted shows Seoul has a full deployment potential of about 10 gigawatts. 3

FREE attended the launch of the initiative. Mayor Park Won-soon and Dr. Byrne were interviewed by leading Korean newspapers on the strategy. During an interview with Kyunghyang Shinmun, Mayor Park underscored FREE’s role, noting that he “had an opportunity to take a view of the downtown area in Seoul from Namsan Mountain with Prof. Byrne. As I talked with him, I realized that Seoul has a significant PV technical potential.” 4

A striking feature of the Solar City Seoul plan is the commitment to increase household-level PV deployment through miniature solar generators installed on rooftops and verandas or so-called “mini-PV” technology. This prong of the plan will engage more than 100,000 households in helping to supply solar energy to the city! This is exactly in tune with the Mayor’s original pursuit of the idea that “citizens are energy.” The initiative will make solar energy a part of the everyday life of Seoul’s citizens and businesses.

FREE has worked extensively on the concept of the “solar city” – the citywide deployment of rooftop solar energy. Our work shows not only that Seoul has significant potential to develop itself as a solar city but that cities like New York, Tokyo, London, Amsterdam, and Munich possess similar resources. 5 Indeed, a paper published in the International Journal of Urban Sciences by the FREE research team highlights the fact that this opportunity is common to most cities around the world. 6 An investigation of the market, finance, and policy considerations associated with solar city deployment found that the concept is not only technically feasible but it also creates practical economic benefits, including job creation and expansion of local green industries, and results in significant environmental benefits by shrinking the city’s carbon footprint by more than 10 percent. 7

“I will make Seoul a place where PV can be found everywhere”, the Mayor said. The FREE team will be there to continue to help make this ambition become unavoidable reality.
