A series of new policies, including a higher cap on surplus electricity sales to the national grid, is reviving Việt Nam''s rooftop solar market, as businesses seek lower energy costs and greener production to meet increasingly stringent export requirements.
Construction is scheduled for completion in the third quarter of next year, with commercial operations and grid connection expected in the fourth quarter of the same year.
Rooftop solar power, especially when combined with Battery Energy Storage Systems (BESS), is emerging as a strategic solution, paving the way for a greener, more flexible and more sustainable industrial park model.
The 800MW floating solar power project on the Sơn La hyower reservoir is expected to supply around 1.25 billion kWh of clean electricity annually to the national grid.
Self-consumption rooftop solar systems would be permitted to export surplus electricity to the national grid, capped at 50 per cent of the total output.
Excess rooftop solar power can be sold to the national grid at no more than 20 per cent of the installed capacity, according to a new Government decree on encouraging self-produced and self-consumed rooftop solar power issued on Tuesday.
The installment and use of rooftop solar power in industrial zones is still struggling due to the lack of detailed regulations and incentive policies to encourage investment.
The power can still be connected to the national grid but transmission can only priced at VNĐ0, a requirement that has sparked controversy with opponents saying the policy is counterproductive as a way of encouraging the public and businesses to participate.
The localisation rate of the supply chain as well as the engagement of Vietnamese firms in providing services to the wind and solar power industry remained modest.
Accordingly, MoIT requested EVN to review, synthesise and propose economic solutions for 14 solar power projects that have been enjoying the incentive price mechanism (FIT) which are not consistent with the content of Resolution No 115/NQ-CP dated August 31, 2021.
