Rooftop solar developer PCG Power plans to launch a trading platform next month to tap into China's growing market for electricity. Policy reforms that have undercut profits on renewables are creating opportunities in trading, Chairman Li Wenxuan said in an interview in Beijing. The company, which also supplies energy storage and manages electricity purchases for large industrial users, is targeting transactions of 10 billion kilowatt-hours in 2027, enough to power a small European country for a year.
