Finnish technology group Wärtsilä will continue to operate and maintain the two power plants that supply nearly all of Timor-Leste’s electricity.
The technology group has signed a renewed three-year Operation and Maintenance (O&M) agreement with Electricidade De Timor-Leste, Empresa Pública (EDTL, EP). The deal covers the Hera and Betano power plants, which together provide 255 megawatts of capacity to the national grid.
For Timor-Leste, securing uninterrupted power generation is essential: the two facilities are the country’s only grid-connected power plants. Wärtsilä has overseen their operation since they were commissioned in 2012. Both sites run on Wärtsilä 46 engines. The new agreement was booked in the company’s second quarter of 2025.
“These power plants are a valuable national asset and critical to the country’s industrial and consumer electricity supply. Reliable performance is therefore essential, and Wärtsilä’s high-quality service has provided the peace of mind needed,” says Paulo da Silva, President Director of EDTL, EP.
Shift to Renewable Energy
Timor-Leste is also preparing to expand its renewable energy production. The government plans to install solar panels and battery storage systems within the next two years.
Wärtsilä will support the transition by advising on how to integrate the new renewable capacity with the existing engine-based generation while maintaining grid stability.
“Our extensive experience in O&M services for power plant operators worldwide allows our customers to focus on their core business, while we ensure their plants operate efficiently and reliably,” says Kari Punnonen, Energy Business Director for Australasia at Wärtsilä Energy.
