Huadian Power International's (HKG:1071, SHA:600027) output fell 6.4% year over year to 120.6 million megawatt-hours in the first half, according to a Thursday filing with the Hong Kong bourse.
Total on-grid power declined 6.5% to 113.3 million MWh.
The decline is attributable to loose supply and demand of power in partial regions, among other factors, the filing said.
