When the question turns to who can build the complex infrastructure that powers modern economies, one Chinese construction company has demonstrated a capacity that extends to more than 30 countries and includes a portfolio valued at over $35 billion, a scale of operation that speaks to both technical capability and sustained execution.
SEPCOIII Electric Power Construction Co., Ltd. (hereinafter referred to as SEPCOIII), recognized with a 2025 Global Recognition Award, has built its reputation not through marketing narratives but through the delivery of power plants, renewable energy systems, and infrastructure that operate in the deserts of Saudi Arabia, the coastlines of Oman, and across Africa and South Asia. The company’s trajectory reveals a story of methodical expansion into increasingly complex technical territory, from thermal power stations to offshore wind farms and nuclear facilities.
Project Introduction
Saudi Rumah-1 IPP CCGT Project receives a Global Recognition Award, contributing to Saudi Arabia’s “Vision 2030” and “Net Zero 2060” Goals. Recently, the Rumah-1 1800MW Combined Cycle Power Plant Project (hereinafter referred to as the “Rumah-1 Project”), jointly developed by ACWA Power, SEC, and KEPCO, and with China Company Limited (the EPC contractor) selected after the bidding process, and jointly constructed with Doosan Group, has successfully won a global recognition award for its massive 1800MW installed capacity, outstanding green energy attributes, and profound impact on the regional energy landscape. Located in central Saudi Arabia, approximately 80 kilometres northeast of the capital Riyadh, the project is a core pillar of Saudi Arabia’s “Vision 2030” energy strategy.
Its construction and operation will not only inject strong momentum into the optimization of the local energy structure and the safe and stable operation of the power grid, but also mark a global standard for Chinese enterprises in the field of large-scale energy engineering in complex high-temperature desert environments, further expanding the company’s brand influence in the international energy market. From the perspective of Saudi Arabia’s energy strategy, the country has clearly stated two key objectives: first, to achieve a balanced power structure by 2030, with 50% of power generation generated from natural gas and 50% from renewable energy, and to significantly increase the proportion of gas-fired combined cycle power plants to further meet the requirements of power system security and ensure the reliability of power supply; second, to achieve net-zero greenhouse gas emissions by 2060. Rumah-1 IPP CCGT project is a crucial link between these two objectives—as a key supporting project for the “Vision 2030” energy plan, the project, with its massive 1800MW installed capacity, will significantly increase the proportion of gas-fired combined cycle power plants in Saudi Arabia’s overall power generation capacity, providing core support for a balanced energy.
The Scale and Substance of Operations
Saudi Rumah-1IPP CCGT Project Saudi Arabia’s Riyadh Province represents 1,800 megawatts of capacity. Which natural gas as primary fuel, diesel as backup, and air cooling systems, technology choices that reflect practical decisions about fuel availability, grid stability, and environmental considerations. Neither project is theoretical or aspirational; both are under construction or progress through advanced development stages under 25-year operating agreements. The Rumah project operates under a Build-Own-Operate (BOO) structure, managed by ACWA Power, and supports Saudi Arabia’s stated energy development strategy.
The SEPCOIII project portfolio suggests consistent patterns in how the company approaches complex work. The company has undertaken the Alghat 600-megawatt wind farm in Saudi Arabia, the Waad Shamal 500-megawatt wind project, and, most recently, secured an engineering, procurement, and construction contract for a 700-megawatt wind facility at Yanbu, also in Saudi Arabia, under the Kingdom of Saudi Arabia’s National Renewable Energy Program. These projects demonstrate technical capability in renewable energy infrastructure at scales that require precision manufacturing, installation expertise, and supply chain management across international boundaries.
The scope of SEPCOIII international operations extends beyond individual projects to include a regional presence. The company operates across Saudi Arabia, Oman, Jordan, Iraq, Kuwait, the United Arab Emirates, Morocco, and Egypt. In India alone, from 2005 to 2011, SEPCOIII captured approximately 20 percent of the power generation construction market, a concentration of work that required managing complex local employment relationships, supply chains, and regulatory compliance. The company maintains project execution across dozens of simultaneous operations, each with its own technical specifications and stakeholder requirements.
Research, Innovation, and Sustainable Practice
Within the energy construction sector, innovation typically manifests in how companies adapt established technologies to new applications, improve efficiency margins, reduce environmental impact, or lower construction timelines and costs. SEPCOIII operates dedicated research and development initiatives focused on solar power generation, seawater treatment, and low-carbon energy technologies. These efforts align with market trajectories rather than speculative futures because solar capacity continues expanding globally, seawater desalination addresses critical water shortages in arid regions, and low-carbon energy solutions address regulatory and commercial pressures across most developed and developing economies.
The sustainability focus evident in SEPCOIII’s significant contract commitments reflects the integration of environmental considerations into project design. Saudi Rumah-11 IPP CCGT incorporates Carbon Capture and Sequestration readiness, indicating that SEPCOIII technical planning considers potential future regulatory requirements and carbon management infrastructure. The air cooling systems employed in the company’s recent projects represent practical choices that reduce freshwater consumption and environmental impact compared to traditional cooling methodologies. These options are particularly significant in water-stressed regions.
SEPCOIII service programs operate across continents and timeframes measured in decades. The company provides construction services, operational management, and maintenance across extended project lifespans. This long-term engagement model creates incentives for quality construction and ongoing performance optimization. Communities across the Middle East, North Africa, and South Asia rely on power infrastructure that SEPCOIII has built and continues to maintain, a responsibility that extends beyond commercial obligation and reflects the accountability embedded in how the company manages infrastructure that supplies electricity to industrial facilities, commercial enterprises, and residential consumers.
A Model of Sustained Achievement
The recognition of SEPCOIII with the 2025 Global Recognition Award reflects consistency in execution across multiple technical disciplines and geographic regions. The company has not pursued a strategy of dramatic technological leaps; instead, it has focused on managing increasingly complex projects with precision and reliability. Alex Sterling, a spokesperson for the Global Recognition Awards panel, noted, “SEPCOIII’s comprehensive work across leadership, service, research, and innovation, combined with its demonstrated commitment to sustainable energy solutions and international collaboration, represents the standard of achievement that the Global Recognition Award seeks to honor.”
The trajectory of SEPCOIII demonstrates that sustained achievement in infrastructure development extends beyond individual projects to include consistent capability across multiple dimensions over extended periods. The company’s growth reflects market expansion in global energy infrastructure, strategic positioning in renewable energy development, and operational frameworks that manage complexity across borders and diverse regulatory environments. The range of SEPCOIII technology portfolio, from concentrated solar and photovoltaic systems to wind and nuclear facilities, reflects client demand and the company’s capacity to mobilize engineering talent, manage supply chains, and execute at scale.
SEPCOIII continues to establish itself as one of the leading international engineering and construction firms through the methodical execution of increasingly significant projects and the consistent advancement of sustainable infrastructure solutions. The company’s success is measured in practical terms that matter in infrastructure: power plants that operate reliably, communities that receive electricity, nations that advance their energy independence, and environmental impact managed through technical solutions. Over the course of decades, SEPCOIII has consistently demonstrated operational excellence and technical competence in complex infrastructure development, establishing its reputation in the global energy sector.
