TNB Research & Sedania to Harness Energy from Excess Water at Johor Dam


Tenaga Nasional Berhad’s (TNB) wholly-owned subsidiary, TNB Research Sdn Bhd (TNBR) and SEDANIA Innovator Berhad’s (SEDANIA) Sustainable Energy arm, SEDANIA Technologies Sdn Bhd have formed a partnership to evaluate the potential of harnessing energy from excess water in dams and water reservoirs throughout Malaysia.

Under the partnership, SEDANIA will deploy the energy-efficient micro-hydropower turbines developed by TNBR to generate electricity from released water at dams. Each of these microhydropower turbines with a capacity of 30 - 40 kilowatts each can generate up to 305,000 kilowatt-hours of electricity per year. With over 70 water dams and reservoirs located
throughout Malaysia, the potential from such micro hydropower energy source is estimated at over 40 gigawatt-hours per year, enough to provide carbon-free electricity to about 10 thousand homes.

The first project by the two partners is for a dam project in Kota Tinggi, Johor. SEDANIA was awarded by a leading multinational oil and gas company with a job to assess and propose the feasibility of deploying energy-efficient micro hydropower solutions to generate electricity from released water.

SEDANIA’s role covers the financial and technical aspects of the project while TNBR provides the technical expertise through the design and installation of the micro-hydropower turbines.

Commenting on the potential opportunities in this area, SEDANIA Chief Executive Officer Daniel Ruppert said, “Together with TNBR, we aim to equip dams in Malaysia with energyefficient micro-hydropower turbines, thereby enabling all our clients to use the dam’s surplus water as an energy source.”
