Malaysia: Tenaga Nasional Bhd (TNB) is investing US$50m in two waste heat recovery (WHR) plants to generate electricity through the recovery of exhaust waste heat from two cement plants operated by Negeri Sembilan Cement Industries. TNB's wholly-owned subsidiary TNB Repair and Maintenance Sdn Bhd will develop and operate the plants and raise the necessary financing.
Negeri Sembilan Cement owns two cement plants in Bukit Keteri, Perlis and Bahau, Negeri Sembilan with a total production capacity of 7.2Mt/yr. TNB said that the WHR plants will have a combined power generation capability of 23MW, giving Negeri Sembilan a 9-12% saving on its electricity cost.
The group said its venture into the waste heat recovery development will provide a new business opportunity in promoting energy efficiency, green technology and a sustainable long-term energy solution.
