High-efficiency step-up substations engineered for immediate integration into Uruguay's national transmission network.
Uruguay stands as a global beacon for renewable energy integration, frequently generating over 95% to 98% of its annual electricity from wind, solar, biomass, and hydro sources. Under the regulation of the state utility UTE (Administración Nacional de Usinas y Trasmisiones Eléctricas) and the wholesale market administrator ADME, the transmission infrastructure requires exceptional stability to handle high wind-power penetration.
Wind power step-up substations (commonly raising voltages from turbine-generation levels of 690V up to collector system levels of 30kV, 31.5kV, or 33kV at 50Hz) are the critical links in this energy chain. Given the geography of Uruguay—characterized by rolling hills in Tacuarembó, Rivera, and Maldonado, and saline coastal breezes along Rocha—the engineering demand for these substations goes far beyond standard electrical configurations.
For coastal installations, corrosion class C4-H to C5-M (ISO 12944) paint protection is mandatory to combat saline-heavy atmospheres. Inland regions face high humidity levels and sudden thermal swings, requiring intelligent dehumidification systems inside switchgear compartments.
Furthermore, UTE’s strict grid code mandates precise reactive power control and fault ride-through (FRT) capabilities. Our substations incorporate intelligent remote terminal units (RTUs) that integrate seamlessly with SCADA systems using IEC 61850 protocols, enabling real-time curtailment and voltage regulation directly from Montevideo's dispatch centers.
Choosing the right design architecture is vital for minimizing levelized cost of energy (LCOE) and guaranteeing 25+ years of operational lifecycle.

Zhejiang Zeno Electric Co., Ltd. is a national high-tech enterprise located in Ningbo, with a registered capital of 52 million yuan. The company integrates research and development (R&D), manufacturing, sales, and service of advanced power equipment and energy systems.
Rooted in Ningbo and supported by a strong engineering and technical team, Zeno Electric has steadily expanded its business across China and international markets. Through continuous innovation and quality-driven development, the company has become a trusted provider in the power and energy industry, with growing influence in both utility and industrial sectors.
With a focus on sustainable development and smart energy transformation, we are committed to delivering safe, efficient, and intelligent power solutions that support the global transition toward cleaner and more digitalized energy systems.
Zhejiang Zeno Electric Co., Ltd. specializes in power equipment and integrated energy system solutions. Our product portfolio covers a wide range of advanced technologies, including:
In addition, we undertake turnkey power engineering projects up to 220kV, providing end-to-end services that include system planning, engineering design, equipment manufacturing, installation, commissioning, and long-term maintenance.
Equipped with state-of-the-art machinery in Ningbo, Zhejiang, Zeno Electric guarantees reliability through precision manufacturing and zero-compromise testing protocols.
Zhejiang Zeno Electric Co., Ltd. is strategically based in **Ningbo, China**, home to the world’s busiest port by cargo tonnage. This allows us to orchestrate highly optimized, direct shipping routes to the **Port of Montevideo, Uruguay**. Our logistics management ensures that large-scale containerized and prefabricated substations are securely packaged, sealed with anti-corrosion barrier wraps, and shipped with real-time GPS tracking.
By sourcing raw materials—such as high-permeability grain-oriented silicon steel (GOES), high-purity copper windings, and eco-friendly insulating oils—from China's highly consolidated electrical supply chain, we achieve substantial cost advantages. We pass these savings directly to utility developers in South America, lowering the CAPEX of wind farms while maintaining strict international standards.
Every single substation manufactured at our facility undergoes comprehensive factory acceptance testing (FAT) before shipment. We simulate harsh operational environments, testing insulation resistance, winding resistance, voltage ratio, phase relationship, no-load loss, load loss, and dielectric strength.
Our manufacturing processes align strictly with the **IEC 60076** standard series for power transformers and **IEC 62271** for high-voltage switchgear. Furthermore, we support developers in achieving compliance with Uruguay’s **LATU (Laboratorio Tecnológico del Uruguay)** and the regulatory audits of **UTE** to ensure smooth grid connections and commercial operation date (COD) targets.
From compact pad-mounted designs to heavy-duty containerized systems, explore our factory-direct step-up solutions for international energy grids.
