TNB Research, Sedania to explore harnessing energy from Johor dam

PETALING JAYA: Tenaga Nasional Bhd’s (TNB) wholly-owned subsidiary, TNB Research Sdn Bhd (TNBR) has partnered with Sedania Technologies Sdn Bhd (STSB) to evaluate the potential of harnessing energy from excess water in dams and water reservoirs throughout Malaysia.


Under the partnership, STSB – Sedania Innovator Bhd’s (Sedania) sustainable energy arm – will deploy energy-efficient micro-hydropower turbines developed by TNBR to generate electricity from water released from dams, said TNB and STSB in a joint statement yesterday.


Each micro-hydropower turbine has a capacity of 30-40 kilowatts, capable of generating up to 305,000 kilowatt-hours of electricity per year, Bernama reported.

“With over 70 water dams and reservoirs located throughout Malaysia, the potential micro hydropower energy source is estimated at over 40 gigawatt-hours per year, enough to provide carbon-free electricity to about 10 thousand homes,” they said.


STSB will cover the financial and technical aspects of the project, while TNBR will provide its technical expertise through the design and installation of the micro-hydropower turbines.

TNB said the first project under the partnership involves a dam project in Kota Tinggi, Johor, where STSB had been tasked by a leading multinational oil and gas company to assess the feasibility of deploying energy efficiency micro hydropower solutions to generate electricity from released water.



Sedania’s chief executive officer, Daniel Ruppert said the partners aim to equip all dams in Malaysia with energy-efficient micro-hydropower turbines, utilising the dam’s surplus water as an energy source.


“As an environmental, social and governance (ESG)-driven organisation with a vision of helping corporations reduce their carbon footprint, Sedania is well-positioned to accelerate the sustainability agenda, together with the support of TNBR,” he said.


TNBR managing director, Mohd Hariffin Boosroh, said TNB was championing responsible and inclusive energy transition, with the aim of achieving net-zero carbon emission by 2050.

“With that goal in mind, TNB is investing in new green technology such as this efficient micro-hydropower turbine developed by our researchers at TNBR.


“This partnership illustrates how research and industry collaboration plays an influential role in the development of innovative and sustainable solutions for Malaysia,” he said.

TNB added as the technology is developed domestically, it will also benefit local industries involved in the manufacturing, commissioning, operations and maintenance of micro-hydropower turbines.


Sedania is a public-listed technology company and provides sustainable energy saving solutions and sustainable healthcare products.


Since its listing in 2015, it has invested in innovative businesses which have set their goal to help stop climate change by reducing greenhouse gases.
