ACWA Signs Mongolia Renewable Export MoU at Riyadh Energy Week

ACWA Power, the Riyadh-headquartered global leader in power generation and green hydrogen, signed a memorandum of cooperation with Mongolia’s Sun Steppe Power on October 13, 2026, in the presence of Saudi Minister of Energy Prince Abdulaziz bin Salman bin Abdulaziz and Minister of Industry and Mineral Resources Bandar bin Ibrahim Al-Khorayef, alongside ACWA Chairman Mohammad Abunayyan. The agreement, concluded on the sidelines of the 25th WPC Energy Congress hosted by Saudi Arabia in Riyadh, sets out a joint framework to explore the cross-border export of renewable electricity generated in Mongolia to China, with a targeted project capacity of 4.5 gigawatts supported by a 500 megawatt-hour battery energy storage system.

The memorandum was announced through the Saudi Press Agency, the Kingdom’s official news authority, underscoring the transparency with which Saudi Arabia communicates major energy developments to international audiences. For a global readership tracking the energy transition, the deal matters because it positions a Saudi champion at the center of Northeast Asia’s clean power corridor. It also demonstrates how the Kingdom’s energy expertise, honed through decades of hydrocarbon leadership and accelerated under Vision 2030, is now being exported as a service to other nations seeking to decarbonize while growing their economies. Could this agreement become a template for how Saudi firms help third countries monetize their renewable resources?

Context and Background

The agreement was signed during the 25th WPC Energy Congress, a flagship gathering of the global petroleum and energy industry that Saudi Arabia is hosting in Riyadh from October 13 to 15, 2026, as part of Energy Week. The Congress brings together ministers, chief executives, and technical experts from across the world’s energy value chain, and it has provided a platform for the Kingdom to showcase both its conventional energy strengths and its rapidly expanding renewable and storage capabilities. The presence of the Minister of Energy and the Minister of Industry and Mineral Resources at the signing reflects the seriousness with which the Saudi government views cross-border electricity cooperation.

ACWA Power has grown from a domestic developer into one of the world’s largest private-sector power and water companies, with a portfolio spanning solar, wind, green hydrogen, desalination, and battery storage across the Middle East, Africa, Central Asia, and Southeast Asia. Mongolia, for its part, possesses some of the world’s strongest wind and solar resources, particularly in the Gobi Desert, but has historically lacked the transmission infrastructure and capital to export that potential at scale. China, its southern neighbor, is the world’s largest electricity consumer and is actively integrating more renewable power into its grid. Why is this particular combination of Saudi capital, Mongolian resources, and Chinese demand attracting so much attention from energy analysts?

The memorandum follows a broader pattern of Saudi energy diplomacy in 2026, in which the Kingdom has deepened ties with Central and Northeast Asian nations through investment, technology transfer, and infrastructure partnerships. It also builds on ACWA Power’s established track record of delivering utility-scale renewable projects on time and at competitive tariffs, a reputation that has made it a preferred partner for governments seeking to attract private capital into their energy sectors. For Mongolia, partnering with a Saudi firm offers access to financing, engineering depth, and operational experience that would be difficult to assemble domestically in the near term.

Key Details of the Memorandum

Under the terms announced by the Saudi Press Agency, ACWA Power and Sun Steppe Power will jointly explore opportunities to develop renewable power generation projects in Mongolia for the purpose of exporting electricity to China. The scope of cooperation covers utility-scale battery storage for solar and wind power, as well as the transmission and export infrastructure required to deliver electricity to China or to other markets that the two companies may agree upon. The memorandum also establishes a basis for assessing a cross-border project with a targeted capacity of 4.5 gigawatts, supported by a 500 megawatt-hour battery energy storage system.

To put the 4.5-gigawatt target in perspective, that capacity is roughly equivalent to the output of several large conventional power plants and could supply clean electricity to millions of homes and businesses. The accompanying 500 megawatt-hour battery system is designed to smooth the variability of solar and wind generation, helping to ensure that exported power meets the reliability standards demanded by grid operators. The inclusion of transmission and export infrastructure in the memorandum is significant because cross-border electricity trade requires not only generation assets but also high-voltage lines, converter stations, and regulatory arrangements between the countries involved.

The signing took place in the presence of Prince Abdulaziz bin Salman bin Abdulaziz, Saudi Minister of Energy, and Bandar bin Ibrahim Al-Khorayef, Minister of Industry and Mineral Resources, as well as ACWA Chairman Mohammad Abunayyan. Their attendance signals that the project is viewed as a strategic initiative rather than a purely commercial transaction. Does the involvement of two senior Saudi ministries suggest that the Kingdom intends to play a long-term institutional role in Northeast Asian energy trade, beyond the initial project?

International and Regional Impact

The memorandum has implications that extend well beyond the three countries directly involved. For Mongolia, it offers a pathway to convert its abundant but landlocked renewable resources into export revenue, a longstanding economic ambition that has been constrained by the absence of transmission links and investment capital. For China, it represents an additional source of clean electricity that can help meet rising demand while supporting its own decarbonization goals. For Saudi Arabia, it demonstrates that the Kingdom’s energy companies are capable of operating at the frontier of cross-border renewable trade, not merely as project developers but as architects of regional energy corridors.

The agreement also reinforces Saudi Arabia’s position as a convening power in global energy affairs. By hosting the 25th WPC Energy Congress during Energy Week in Riyadh, the Kingdom has created a venue where deals of this kind can be announced and scrutinized by the international community. That convening role is itself a form of soft power, allowing Saudi Arabia to shape the agenda on energy transition, storage, and grid integration. How might this model of Saudi-led energy cooperation influence similar initiatives in Central Asia, Africa, or South America in the coming years?

Regional analysts are likely to view the memorandum as part of a wider trend in which Gulf energy champions increasingly invest in and operate assets far from home. This trend reflects both the maturity of Saudi renewable expertise and the growing global demand for capital to finance the energy transition. It also highlights the importance of battery storage as an enabling technology for cross-border renewable trade, since intermittent solar and wind generation must be balanced to meet the quality-of-service expectations of importing countries.

Economic and Strategic Significance

From an economic standpoint, the memorandum opens the door to a project that could involve billions of dollars of investment across generation, storage, and transmission assets. While the memorandum itself is a framework for exploration rather than a binding financial commitment, it establishes the commercial and technical groundwork that typically precedes final investment decisions. ACWA Power’s participation brings with it a demonstrated ability to structure bankable projects, attract international lenders, and manage complex multi-jurisdictional operations. For Mongolia, the potential benefits include job creation, technology transfer, and a new source of foreign exchange earnings.

Strategically, the agreement aligns with Saudi Arabia’s interest in diversifying its international partnerships and in positioning itself as a reliable supplier of energy solutions, not only of molecules but also of electrons and expertise. The Kingdom’s Vision 2030 reform agenda explicitly calls for expanding non-oil exports and for Saudi firms to become global leaders in high-value sectors, including renewable energy. A successful cross-border project in Northeast Asia would serve as a powerful reference case for ACWA Power and for other Saudi companies seeking to expand abroad. Could the commercial and diplomatic dividends of this single memorandum extend far beyond the electricity it might one day deliver?

The memorandum also has implications for the global battery storage industry, given its explicit inclusion of a 500 megawatt-hour system. As renewable penetration rises worldwide, storage is becoming the critical enabler of grid stability and of round-the-clock clean power supply. By embedding storage in a cross-border export project, the partners are signaling that reliability and decarbonization can advance together, a message that resonates with policymakers in both importing and exporting nations.

Vision 2030 Alignment

The ACWA Power–Sun Steppe Power memorandum is a clear expression of Saudi Arabia’s Vision 2030 objectives, which seek to transform the Kingdom into a diversified, globally engaged economy. Under the Vision, Saudi companies are encouraged to export their capabilities, to forge international partnerships, and to contribute to the global energy transition. ACWA Power’s role in the agreement exemplifies these goals, demonstrating that Saudi expertise in large-scale energy development is now a sought-after export in its own right. The Ministry of Energy and the Ministry of Industry and Mineral Resources, both of which were represented at the signing, have been central to creating the policy environment that makes such international ventures possible.

Looking ahead, the memorandum provides a foundation for deeper cooperation between Saudi Arabia and Mongolia, and potentially for a broader Saudi role in Northeast Asian energy trade. If the 4.5-gigawatt project advances, it would stand as a landmark example of South–South and cross-regional collaboration, with a Gulf champion enabling a landlocked nation to reach a major market. For international observers, the signing is a reminder that Saudi Arabia’s energy story is no longer confined to oil. It is a story of diversification, innovation, and partnership, told through deals like this one and carried forward by the Kingdom’s Vision 2030 ambitions. Will the next decade see Saudi firms become indispensable partners in the clean energy systems of Asia and beyond?
