PECC2 Energy Services and Engineering Co., Ltd. (PESE) has established and continues to strengthen its position as a leading provider of Operation & Maintenance (O&M) services.

Power plants are developed in a wide variety of geographical environments. Their planning and construction depend on the characteristics of each power generation technology and may be located near residential areas, in remote regions, or in locations selected specifically for their renewable or conventional energy potential.

Power Generation Technologies and Their Typical Locations

Thermal Power Plants

Thermal power plants are typically built in flat land areas, coastal regions, or near major industrial zones where ports, fuel storage facilities, and transportation infrastructure are readily available. These locations are ideal for supplying large electricity loads while ensuring a stable baseload power source.

Hydropower Plants

Hydropower plants are best suited to mountainous areas, highlands, and regions with abundant rivers and streams. Steep terrain combined with reliable water resources provides ideal conditions for generating electricity from flowing water.

Wind Power Plants

Wind farms perform most efficiently in coastal areas, offshore locations, and wide-open plains with minimal obstacles. Regions with consistent year-round wind speeds maximize turbine efficiency and increase power generation.

Solar Power Plants

Solar power plants are ideally located in areas with high solar irradiation, long sunshine hours, and large expanses of available land, such as arid and semi-arid regions. Stable weather conditions with limited cloud cover enable photovoltaic systems to achieve maximum performance.

Each type of power plant operates under unique geographical and environmental conditions. These differences create distinct Operation and Maintenance (O&M) requirements, demanding technical service providers with the expertise and flexibility to operate efficiently across diverse terrains.

Managing a power generation portfolio exceeding 5,000 MW while consistently maintaining an impressive 98–99% Availability Factor, PECC2 Energy Services and Engineering Co., Ltd. (PESE) has established itself as a leading provider of professional O&M services. Behind these outstanding performance indicators lies the ability to overcome some of the industry's most demanding geographical and environmental challenges.

Overcoming Harsh Coastal and Offshore Conditions

At coastal and offshore projects such as Tan Thuan Wind Farm (75 MW), Vinh Tan Thermal Power Plant (>1,200 MW), and Duyen Hai 2 Thermal Power Plant (1,320 MW), high humidity, salt-laden air, and frequent storms significantly accelerate equipment corrosion.

To address these conditions, PESE implements comprehensive industrial maintenance programs, including structural steel quality control, corrosion protection for Balance of Plant (BOP) systems, and scheduled wind turbine blade maintenance. These practices ensure equipment safety, reliability, and long-term operational performance even in the harshest marine environments.

Delivering Fast Maintenance Across Large-Scale Solar Farms

In high-temperature and remote regions, solar power plants such as Hoa Hoi Solar Power Plant (257 MWp), Song Luy Solar Power Plant (46.7 MWp), and the BIM Solar Complex (405 MWp) extend across vast areas.

Maintaining these facilities requires rapid inspection and maintenance activities. PESE utilizes thermal drone technology to detect abnormal photovoltaic module temperatures, enabling early fault identification, minimizing downtime, and improving overall plant efficiency.
