Thailand makes green push with floating hydro-solar power project – EQ Mag Pro

A vast array of solar panels floats on the shimmering waters of a reservoir in northeast Thailand, symbolising the kingdom’s drive towards clean energy as it seeks carbon neutrality by 2050.

The immense installation, covering 720,000 square metres of water surface, is a hybrid system that converts sunlight to electricity by day and generates hydropower at night.

Touted by the authorities as the “world’s largest floating hydro-solar farm”, the Sirindhorn dam project in the northeastern province of Ubon Ratchathani is the first of 15 such farms Thailand plans to build by 2037.

The kingdom is stepping up efforts to wean itself off fossil fuels, and at the COP26 climate conference in Glasgow last year, Prime Minister Prayut Chan set the target of carbon neutrality by 2050 followed by a net-zero greenhouse emissions by 2065.

The Sirindhorn dam farm – which began operations last October – has more than 144,000 solar cells, covering the same area as 70 football pitches, and can generate 45 MW of electricity.

“We can claim that through 45 megawatts combined with hydropower and energy management system for solar and hydro powers, this is the first and biggest project in the world,” Electricity Generating Authority of Thailand (EGAT) Deputy Governor Prasertsak Cherngchawano told AFP.

The hybrid energy project aims to reduce carbon dioxide emissions by 47,000 tonnes per year and to support Thailand’s push toward generating 30 per cent of its energy from renewables by 2037, according to EGAT.

But hitting these targets will require a major revamp of power generation.

Thailand still relies heavily on fossil fuel, with 55 per cent of power derived from natural gas as of October last year, compared with 11 per cent from renewables and hydropower, according to the Energy Policy and Planning Office under the Ministry of Energy.
