France's EDF raises cost estimates for UK's Hinkley Point after review

French state-owned utility EDF flagged a construction cost overrun at its Hinkley Point C nuclear power station in Britain on Monday, in a new blow for a group of EDF projects already facing delays, rising costs and other problems. After a review, EDF said the cost of completion had increased by 1.5-billion pounds to stand at £19.6-billion ($25.5-billion) – an increase that means its predicted rate of return on investment will fall to 8.5% from 9% previously.
