Trinasolar has supplied a 3 MWp solar PV system and a 10 MWh battery energy storage system for Corona Resort in Phu Quoc, Vietnam. The addition expands the resort’s existing 5.5 MWp solar installation and is designed to improve renewable energy utilisation and electricity demand management.
Corona Resort in Phu Quoc, Vietnam, is expanding its renewable energy infrastructure with an additional 3 MWp solar photovoltaic (PV) system and a 10 MWh battery energy storage system (BESS) supplied by Trinasolar. The project is intended to increase the resort’s ability to consume locally generated renewable electricity while improving the management of its electricity demand.
The installation combines Trinasolar’s Vertex N 725W (NEG21C.20) modules with its Trina Storage Elementa 2 battery storage solution. Vietnamese renewable energy company Nam Viet Green Energy JSC is responsible for developing the project, including engineering, procurement, construction and installation activities.
The new system will supplement the resort’s existing 5.5 MWp solar PV installation, creating a larger on-site renewable generation base. The addition of battery storage will allow electricity generated during periods of strong solar production to be retained for later use, helping the resort make better use of its renewable generation throughout the day.
The 10 MWh BESS uses an AC-coupled configuration, providing the facility with an additional mechanism to manage fluctuations in electricity demand. Stored solar power can be discharged when consumption rises, reducing the need to draw as much electricity from the grid during higher-demand periods.
For a large tourism facility such as Corona Resort, combining solar generation with storage can provide greater control over energy consumption. The configuration can improve renewable energy utilisation, support peak-demand management and reduce the amount of surplus solar generation that would otherwise remain unused.
The project is scheduled to be connected to the grid and commence commercial operations by mid-September 2026. Its development comes as Vietnam seeks to strengthen its electricity infrastructure amid rising power demand and increasing deployment of renewable energy across the country.
Energy storage is expected to play a growing role in Vietnam’s power system as the contribution from variable renewable sources increases. The country is targeting 10,000 MW to 16,300 MW of BESS capacity by 2030, creating opportunities for storage deployment across utility-scale, commercial and industrial applications.
The Corona Resort installation also illustrates how commercial and tourism facilities can combine on-site solar generation with battery storage to improve energy management. Rather than relying exclusively on the grid to meet changing consumption patterns, businesses can use stored renewable electricity to increase the proportion of clean power consumed at their facilities.
The project reflects a broader shift in Southeast Asia towards integrated solar-plus-storage systems for commercial users. With electricity demand increasing and renewable generation becoming more prominent, battery storage is emerging as an important tool for improving the flexibility, reliability and economic value of distributed renewable energy projects.
For Trinasolar, the deployment further demonstrates the application of its solar and storage technologies beyond conventional utility-scale projects, while the Corona Resort project highlights the potential for integrated renewable energy systems to support the decarbonisation of large commercial facilities.
