Energy transition in South Korea without ideological divides: Huge opportunities for German companies in Busan

Multi-billion dollar offshore wind market: Huge opportunities for German companies in Busan

While in Europe, and especially in Germany, the energy transition is often accompanied by heated debates about bans, heating regulations, and ideological battles, South Korea is taking a completely different approach. Far removed from moral appeals, the country is undergoing a tough, technocratic system change: In Seoul, the energy transition is not seen as a form of education, but rather as a hard-nosed industrial policy and an engine of growth.

The South Korean government has presented an ambitious roadmap that envisions an installed capacity of 100 gigawatts of renewable energy by 2030 – a tripling of the current capacity. However, unlike many Western models, South Korea is pursuing a pragmatic mix: massive investments in solar and offshore wind farms are complemented by grid modernization through AI and "energy highways," as well as the continued use of nuclear power as a bridging technology.

Energy transition without ideological fronts and why Europe must not miss out on it

South Korea is approaching its energy transition not as a moral campaign, but as an industrial policy and technological challenge. The government aims for 100 gigawatts of installed renewable energy capacity by 2030, a significant jump from the current 38 to 40 gigawatts. This figure is not only ambitious, it marks a profound systemic shift: the existing mix of coal, gas, and nuclear power will be gradually replaced by a mix of solar energy, onshore and offshore wind, storage, and modernized transmission grids. The new Ministry of Climate, Energy and Environment (MCEE) explicitly positions the energy transition as a "growth engine" and not merely as a cost-saving measure or a means of reducing dependency.

A key difference from many European energy transition programs is the integration with industrial and infrastructure policy. The measures are based less on prohibitions and more on incentives and infrastructure: expansion of electricity grids, intelligent grid management, development of energy storage, and a gradual phase-out of coal-fired power plants, linked to a clear timetable until 2040. South Korea's economic structure – strongly oriented towards industry, exports, and technology – makes a stable, competitive energy supply a crucial factor for its economic competitiveness. This ensures that the energy transition does not fade into the political background but is understood as an integral part of economic competitiveness.

Solar, wind and the move to the high-performance grid

The core of the Energy Transition Roadmap 2026 lies in a massive expansion of solar and wind power capacity. For photovoltaics, the government plans a significant increase in available land, for example through agrivoltaics, the use of landfills, brownfield sites, and areas on water. At the same time, setback rules and permitting procedures are being adapted to shorten project timelines. The targets call for a significant expansion of solar energy by 2030, which will give solar power a considerably larger share of the overall energy mix.

The expansion of onshore and offshore wind power continues to have a significant structural impact, particularly along the west and south coasts and off the east coast, where large, sometimes deep water zones make the development of floating offshore wind projects attractive. Offshore wind is seen not only as a source of electricity but also as the nucleus of a new maritime industry: shipbuilding, port logistics, assembly, specialized transport, and maintenance services. Plans call for the addition of approximately 4 gigawatts of offshore wind capacity annually from 2030 onward, which will transform the sector into a continuous mass market.

The continued existence of this decentralized generation can only function via a modernized grid. South Korea is therefore simultaneously pursuing the development of an "Energy Highway" infrastructure with high-voltage direct current (HVDC) lines, connecting large generation centers along the coasts with the industrial and consumption centers inland. By 2029, an additional 2.3 gigawatts of energy storage systems are to be installed and virtual power plants activated to flexibly manage loads. AI-based grid management and regional microgrids are intended to increase grid stability and improve public acceptance of renewable energies. This step is long overdue: previous grid structures were geared towards centralized, dispatchable power plants, which has thus far limited a high proportion of variable generation.

Market control, price incentives and the role of nuclear power

South Korea's energy transition is being driven not only by administrative regulations but also by market mechanisms and tariff reforms. The government is announcing changes to electricity tariffs designed to better align industrial consumers with the load curve: higher prices in the evening and lower prices during the day. This will incentivize load shifting, flexible operating hours, and the use of storage. At the same time, the government is preparing to repurpose the connections of decommissioned coal-fired power plants for renewable energy projects, thereby utilizing grid infrastructure efficiently and supporting regional structural transformation programs.

The role of nuclear power remains a central issue in South Korea. Unlike some European countries, the government is not planning a complete phase-out, but rather the continued use of nuclear power as a "transitional and stabilizing technology." New nuclear power plants will continue to be built and commissioned to maintain security of supply, while the share of renewable energies gradually increases. The official line is that nuclear power, together with renewable energies and storage, forms a low-carbon bridge until the system technology and regulations for a fully renewable electricity supply are mature.

This approach is politically sensitive and is controversially discussed by environmental and climate groups, but it reflects economic reality: an abrupt phase-out without functioning alternatives would jeopardize industry and security of supply.

The South as an energy and innovation hub

Of particular interest is the strategic role of South Korea's coastal regions, especially the Busan-Jinhae Free Economic Zone (BJFEZ). This zone is explicitly positioned as a regional hub for offshore wind, energy infrastructure, hydrogen, and smart grids. Its proximity to major ports, maritime industry clusters, and international trade routes gives it a structural advantage: components can be produced, assembled, stored, and exported here. Local authorities are actively seeking international investments, research collaborations, and joint ventures focused on offshore wind, ship components, and maritime logistics.

The development of the BJFEZ is not a side project, but part of a broader industrial strategy. South Korea aims to become not only a consumer of modern energy infrastructure, but also a provider of complex technologies and services. The region benefits from existing supply chains in shipbuilding, steel, electronics, and mechanical engineering. This foundation ensures that rollout costs for offshore projects can be significantly lower than in countries that would have to build their entire supply structure from scratch.

For international companies, especially those from Germany and Europe, this presents a unique combination: high technological expertise, well-developed industrial and infrastructure chains, and a clear political objective. The requirements are high: supply chains are scrutinized for efficiency, quality, and integrity, and the projects demand comprehensive energy and grid solutions. Those who limit themselves to merely supplying components miss the opportunity to be integrated into the planning and operation of the systems.

Hydrogen and smart grids as strategic fields

Alongside its energy transition, South Korea is developing a hydrogen strategy, which is becoming particularly tangible in the region around Busan and Gyeongnam. The goals range from the production of green hydrogen and its storage to its application in shipping, industry, and long-distance logistics. The government plans to significantly increase hydrogen production and processing capacities to establish a national hydrogen infrastructure. This sector is seen as a bridge between electricity generation from wind and solar energy and the decarbonization of sectors that are difficult to electrify.

There is also a growing focus on smart grids and digital network solutions. The planned use of artificial intelligence for network monitoring and load management is intended to reduce the risk of bottlenecks while simultaneously lowering the costs of backup capacity. Microgrids and distributed energy generation are envisioned in urban and industrial centers as part of a flexible, decentralized system. The integration of consumers, producers, and storage facilities into a digital network model opens up numerous application areas for software solutions, data analysis, and automation.

For European companies, these developments mean more than just export opportunities for individual products. The synergies between German and European technologies on the one hand and the South Korean industrial chain on the other are significant. Experience in system integration, strong automation and software expertise, and network planning skills position the European industry as a strategic partner for the gradual development of a low-carbon energy system in South Korea.

Opportunities and risks for European companies

South Korea's energy transition presents concrete economic opportunities for German and European companies. The combination of high investment needs, technological openness, and clear political objectives creates an environment in which international technology leaders and system integrators can gain a foothold. The requirements are high: the projects demand long-term partnerships, technological reliability, and a deep understanding of local market and regulatory conditions.

For German companies in the fields of plant engineering, electrical engineering, automation, energy storage technology, and software solutions, there is a virtually unique opportunity to enter one of the fastest-growing markets for renewable energies. Proximity to South Korean industrial clusters, particularly in Busan and Gyeongnam, enables short supply chains, rapid iterations, and close collaboration with local partners. European companies that position themselves early in this region can integrate into strategic planning and establish themselves not only as equipment suppliers but also as technology and knowledge partners.

At the same time, there are risks: The political landscape in South Korea is dynamic, investment programs can shift, and regulations are evolving rapidly. Furthermore, competition is intense, as Chinese and Japanese companies, as well as local corporations, are also heavily involved. European companies operating there must be prepared for more complex negotiation structures, longer decision-making processes, and a different culture of collaboration.

Nevertheless, the strategic situation is clear: South Korea is on the verge of becoming one of the leading countries in the integration of renewable energies, hydrogen, and smart grids. The energy transition is not a side issue, but a megaproject with significant economic impact and global ramifications. For Europe, this means that cooperation with South Korea is not only a technological decision, but also an economic policy one. Those who get involved in the country's energy transition early on are investing not just in projects, but in long-term partnerships that extend beyond South Korea's borders and secure their own industry's position in an increasingly globalized energy world.
