JERA and Eneos to develop and operate two gas-fired power units in Chiba

TOKYO, Nov 6 (Reuters) - Japan's biggest power generator JERA and top oil refiner Eneos Holdings 5020.T said on Friday they will jointly develop and operate two gas-fired power-generation units with a combined capacity of 1.74 gigawatts at the Sodegaura power station in Chiba, near Tokyo.
