A large energy unit where 1 megawatt-hour equals 1,000 kilowatt-hours or 3.6×10⁹ joules. Used for power plant generation (e.g., “wind farm produces 50 MWh per day”), large-scale energy storage systems, and industrial park electricity consumption. A core reporting unit in China’s “dual carbon” (carbon peak and neutrality) initiatives, commonly seen in power trading and carbon accounting.
