Greek state-controlled utility Public Power Corp. SA (PPC.AT) reported Thursday a first-half net profit of 18.3 million euros ($23 million), down 85.8% from a year earlier because of higher energy costs and a new lignite levy.

MAIN FACTS:

-Earnings before interest, taxes, depreciation and amortization, or Ebitda, fell to EUR483.4 million from EUR603.8 million a year earlier.

-Turnover increased 8.4% to EUR2.9 billion.

-Its Ebitda margin narrowed to 16.5% from 22.2%.

-Net debt rose to EUR4.7 billion from EUR4.3 billion in the first half last year.

-Chief Executive Arthouros Zervos said higher energy costs,
Greece 's deteriorating economic environment and the lack of liquidity in the market put pressure on group profitability.

-Mr. Zervos said he expects the company's full-year Ebitda margin to be 16%-16.5% as long as
Greece 's macroeconomic environment doesn't deteriorate further.
