Thailand's Metropolitan Waterworks Authority is preparing two major energy transformation initiatives totaling 69 billion baht: a solar rooftop subsidy program targeting 1 million households (50,000 baht per household) to support renewable energy adoption and enable households to sell power back to the grid, plus a 19 billion baht smart grid infrastructure upgrade to manage distributed energy and improve grid control. Both plans are awaiting presentation to the cabinet screening committee within this week and represent significant government effort to address energy security and accelerate decentralized renewable energy deployment.
