T&T Group begins commercial operation of 300 MW Savan 1 wind farm

The plant will export and sell electricity to Vietnam for 25 years.

Vietnamese firm T&T Group has announced that its Savan 1 wind power plant in Laos has reached commercial operation.

In a statement, the company said the plant, which reached a total capacity of 300 megawatts (MW), commenced the operation of 48 wind turbines.

Located in Savannakhet province, Lao People's Democratic Republic, the $768m Savan 1 wind power plant has a total installed capacity of up to 495 MW. It is the largest onshore wind power project that T&T Group has ever invested in, marking the group's first step in its cross-border energy strategy.

The project was granted a concession contract to T&T Group by the Lao Ministry of Planning and Investment starting in January 2025. Under this contract, the Government of the Lao People's Democratic Republic agreed to allow Savan 1 Wind Power Company Limited to design, build, own, and operate the project for a period of 25 years to export and sell electricity to Vietnam.

Phase 1 of the project has an installed capacity of 300 MW, with a total investment of over $490m.

Immediately after receiving the concession contract, T&T Group constructed a 220 kilovolt transmission line over 50 kilometres long from the power plant to the waiting pylons on the Vietnamese side. The transmission line was completed by the end of August 2025.
