After several years of energy crises, political declarations, and loud promises, the world is entering a phase where infrastructure is key. The year 2026 is not a symbolic date for the energy transition — it is the year when a number of major projects move from planning to full operation, establishing a new logic for the global energy balance for decades to come.
Energy megaprojects — LNG terminals, interregional grids, large-scale renewable energy projects, storage systems, and new nuclear solutions — are shaping not only the energy production structure but also the geography of influence. These projects determine which countries have stable access to resources and which remain dependent on external decisions.
Nuclear Energy: 2026 as the Turning Point for Nuclear Power
After more than ten years of stagnation and political caution, nuclear energy is once again taking center stage in the global energy architecture. The year 2026 is viewed by the industry as the year when the largest number of new nuclear capacities in recent decades either come online or enter the final stages of commissioning.
This is not about an abstract "nuclear renaissance" but about concrete infrastructure solutions. In various regions — from Asia to Eastern Europe and the Middle East — large energy blocks are being completed or launched, as well as the first commercial small modular reactor (SMR) projects. Collectively, these projects form a new wave of nuclear generation with a clear pragmatic goal: providing a stable, predictable, and politically controlled source of electricity.
A prime example is the Akkuyu Nuclear Power Plant in Turkey. This is the country’s first nuclear power station, and its construction is entering the critical phase in the middle of the decade. The project holds not only energy significance but also strategic importance, as it establishes a long-term model for base-load generation in a rapidly growing country that aims to reduce dependence on gas imports.
Another notable example is China’s large-scale program to build new reactors, particularly Hualong One-type blocks, which are being gradually commissioned between 2025 and 2027. In this case, China is using nuclear power as a tool for both domestic energy system stability and as an exportable technological platform, reshaping the global nuclear power balance.
The reasons behind nuclear’s resurgence are systemic. First, renewable energy, despite its rapid growth, cannot guarantee energy system stability on its own without large-scale and costly storage solutions. Second, gas, even in the form of LNG, remains vulnerable to geopolitical risks and price fluctuations. In these conditions, nuclear energy is being seen once again as a long-term energy security tool rather than an ideological compromise.
Importantly, most of the new nuclear projects planned for completion by 2026 are being realized in countries where energy is seen as critical infrastructure with long-term state guarantees, not as purely a market segment. China, India, the Gulf States, and parts of Europe are betting on nuclear energy not as a "green alternative," but as base infrastructure capable of functioning for decades, independent of weather conditions and external suppliers.
Thus, 2026 may not be the year nuclear energy triumphs in the public discourse but rather the year of its quiet but definitive return to strategic planning. Nuclear megaprojects will form the foundation of new energy stability and, at the same time, establish new lines of global energy influence.
Reformatting Global Gas Flows and LNG
Despite active discussions on decarbonization, gas will remain a key element of the global energy balance in 2026. The reason is simple: a significant portion of new liquefied natural gas (LNG) infrastructure projects launched after 2022 will reach full or near-full capacity in 2025–2027. This indicates not just a temporary market stabilization but a structural shift in supply directions.
At the center of these changes are new LNG projects in the U.S., Qatar, and African countries. These projects not only increase global supply but also definitively shift the focus from pipeline logic to a more flexible maritime gas trade model. As a result, traditional energy routes are losing their dominant role, and control is shifting to those who own export and regasification infrastructure.
For Europe, 2026 will be the moment of solidifying this new reality. After the emergency deployment of LNG terminals in 2022–2024, the region is transitioning from crisis response to systemic gas flow management. LNG stops being a crisis tool and becomes the foundation of energy security, albeit at a higher price and with greater coordination requirements between countries.
At the same time, gas remains a key balancing resource for energy systems with a high share of renewables. Even under optimistic scenarios for energy storage development, gas-fired power plants will remain the primary tool for compensating for the instability of solar and wind power. This positions gas not as an alternative to nuclear energy but as its functional complement.
Among the gas megaprojects shaping the new market configuration in 2026, two notable examples stand out.
The first is the expansion of Qatar’s North Field gas reservoir, which is essentially the world’s largest LNG project. With the phased introduction of new capacities, Qatar is securing its role as a long-term, predictable LNG supplier for both Europe and Asia. Unlike crisis-driven supplies, this project is based on decades-long contracts, making it an element of structural stability, not temporary market balancing.
The second key example is Golden Pass LNG in the U.S., which will reach a critical launch stage in the middle of the decade. This project is significant not only for its scale but also for the changing role of the United States in the global gas market. The U.S. is gradually transitioning from an emergency supplier to a systemic LNG exporter capable of flexibly redistributing flows between Europe and Asia depending on demand.
The key difference between gas megaprojects and nuclear ones is the nature of control. While nuclear energy ensures long-term internal stability, LNG is creating a new map of interdependencies between exporters, transit hubs, and consumers. This network of connections will determine the energy policy of many states in the second half of the decade.
Renewable Energy: Scale Is Growing, but Gradually
Solar and wind projects are increasingly integrating into systems where stability is ensured by nuclear and gas power generation, not the other way around. This is changing the role of renewable energy from an ideological symbol of the energy transition to a tool for optimizing the energy balance.
The major megaprojects in renewable energy are concentrated in regions with access to cheap capital and centralized planning. The Middle East, China, and Australia are implementing large-scale solar and wind clusters, focused not only on domestic consumption but also on the export of energy-intensive products or synthetic fuels. In these models, renewable energy is part of an industrial strategy, not a standalone sector.
A notable example of this new logic in renewable energy development is the Al Dhafra Solar PV park in the United Arab Emirates. This is one of the largest single solar projects in the world, being built as part of the country’s centralized energy strategy. Its key feature is not just its scale but its integration with the state-controlled grid and long-term contracts. In this model, renewable energy does not replace base-load generation but works alongside nuclear and gas power, reducing the overall cost of the energy balance without sacrificing stability.
At the same time, the key limitation for renewable energy in 2026 remains the problem of storage and grid infrastructure. Even with record investments in battery systems, storage capacity is not keeping pace with the growth of generation. This means that without support from gas or nuclear capacities, renewable energy cannot guarantee uninterrupted supply, particularly in large industrial economies.
Notably, countries with high shares of renewable generation are increasingly revising their approaches to backup power. Gas plants and nuclear blocks are returning to strategic planning as necessary elements of stability, not as temporary compromises. Thus, in 2026, renewable energy is finally becoming integrated into a hierarchical model, where it complements base-load generation but does not replace it.
As a result, renewable energy remains an important element of the global energy mix, but its impact on changing the global energy map is determined not by the number of megawatts installed but by its ability to integrate into control systems, storage, and cross-border coordination.
Ukraine: Between the Constraints of War and Strategic Opportunities
For Ukraine, the year 2026 will unfold under fundamentally different conditions compared to most participants in the global energy market. The full-scale war significantly limits the possibility of large infrastructure projects, increases investment risks, and forces a focus on short-term energy system stability. However, these conditions also create a unique, potentially strong starting position for post-war reconstruction.
In nuclear energy, Ukraine already has a unique advantage: an established base-load generation infrastructure, workforce expertise, and integration with the European energy system. In the medium term, this opens opportunities for both modernizing existing capacities and participating in new nuclear projects, including small modular reactors. If the security situation stabilizes, nuclear energy could remain a key element of the country’s energy autonomy.
The gas sector for Ukraine also remains multidimensional. On one hand, the war significantly limits investments in extraction and new infrastructure. On the other hand, the country’s geographic location, underground gas storage, and experience with cross-border flows provide potential for a role in the European gas system.
Renewable energy in Ukraine under wartime conditions is the most complex segment. Much of the infrastructure is located in high-risk zones, and investment horizons are significantly shortened. However, after the active phase of the war ends, renewable energy could become one of the drivers for rapid recovery — through decentralized projects, local grids, and integration with European electricity markets.
For Ukraine, the key issue is not choosing between nuclear, gas, or renewable energy but the ability to develop a coordinated growth model that combines base-load generation, flexibility, and integration with the EU. The war complicates this process but also makes it inevitable: without strategic energy decisions, post-war recovery risks remaining fragmented.
Conclusion
The year 2026 is not a turning point in the energy transition in its classical sense. Instead, it marks the results of decisions made years earlier and solidifies a new global energy configuration. Nuclear energy returns as the foundation of stability, gas and LNG create a new geography of interdependencies, and renewable generation integrates into the system as a large but structurally dependent element.
The key factor is not the technology itself but control over infrastructure — generation, grids, storage, and cross-border flows. These elements will determine which states achieve long-term energy resilience and which remain vulnerable to external decisions.
Energy megaprojects of 2026 do not change the world overnight, but they set the rules for the next decades.
