Companhia de Electricidade de Macau – CEM, S.A. (CEM; Chinese: 澳電) is a private public utility company with a sole concession to transmit, distribute, sell high, medium and low voltage of electricity in Macau. Besides, CEM owns an installed generation capacity of 472 MW.
From 1906 to 1972, the electricity supply service was managed by the Macao Electric Lighting Company Ltd. (now Melco International Development), which had its headquarters in British Hong Kong. In 1972, due to non-fulfilment of its concession contract with the former Portuguese administration, the company was replaced by CEM.
CEM was restructured with the former Portuguese administration's support in 1982. In 1985, CEM signed the 25-year concession contract. It has since scored achievements in the areas of cost-effectiveness and technology.
In November 2010, the Macau SAR government and CEM signed the Power Supply Contract Extension for 15 years. The new contract terms came into effect on 1 December 2010.
Before 1987, the largest shareholder of CEM was the Government of Macau. But ever since that, the government had been reducing its share until the current 8%. Shares of CEM are currently owned by Sino French Energy Development Co., Ltd. (42%), EDP Asia-Investment and Consultancy Ltd. (21%), Polytec Industrial Ltd. (11%), Asiainvest (IP Holding) (10%), China Power International Holding Ltd (6%), Government of Macau (8%), other 800 local shareholders (2%).
