LISBON, Oct 29 (Reuters) - Portugal's largest utility, EDP , reported on Thursday a 8% drop in its 9-month net profit to 422 million euros ($499 million), hit by lower demand in Iberia and Brazil primarily due to the COVID-19 pandemic and the closure of a major coal plant.

The company, whose main shareholder is China Three Gorges, said its consolidated earnings before interest, taxes, depreciation and amortisation (EBITDA) dipped 2% to 2.63 billion euros between January and September from a year ago.
