TNB’s Nenggiri Dam in Kelantan plays multiple roles


Kuala Lumpur: The proposed Nenggiri Dam hydroelectric power project, to be built 30 kilometers from Gua Musang in Kelantan, will add 300MW to the total installed hydropower Tenaga Nasional Bhd (TNB) of 2536.1MW, once approved by the Energy Commission.

Not only will it enhance the reliability and security of the grid system to serve 6.96 million registered electricity users on the peninsula, but it will also play a multi-pronged role for the country and the Kalantan.

Over the past 72 years, TNB has operated only three hydroelectric dam systems in the country, the Sungai Perak Hydro Scheme (1,249.1MW), Cameron Highlands Scheme (622MW), and Kenyir Scheme (665MW).

“Green” hydropower accounts for only 18% of the TNB capacity in Peninsular Malaysia at present, followed by solar power at 0.6%. Of fossil fuels, coal accounts for 45.6% and gas 35.9%. The combination of these green and fossil fuels allows TNB to have a total generating capacity of 16,030.53 MW.

In 2016, hydropower contributed less than 5% to Malaysia’s energy supply, particularly less than a peak of 29.3% in 1988.

As another promising source of renewable energy, the proposed Nenggiri Dam is gearing up for Malaysia’s renewed interest in green energy.

The Nenggiri Dam project, once awarded to TNB, will embody the NEPCO’s commitment to the government’s strategy to increase power generation from renewable energy (RE) resources.

It reflects TNB’s proactive efforts towards using more renewable energy, as it is now easy to pursue renewable energy generation as a result of technological advances amid increasing awareness towards mitigating climate change.

The contribution of low green energy to TNB’s generation mix will change gradually as TNB aims to have renewable energy account for 40% of its total capacity mix by 2025 as it develops its capacity domestically and in select international markets.

It is not without merit that TNB focus on the renewable energy pathway. Minister of Energy and Natural Resources Datuk Seri, Dr. Shamsul Anwar Nasara, said that the government has set a renewable energy target of 31% of generation capacity for 2025.

Additionally, with the ongoing global energy transition, the energy source of the future is highly favorable to green and renewable initiatives as the world strives to decarbonize and mitigate climate change.

TNB Chairman and CEO Datuk Baharin Din said that the group’s investments towards an efficient energy transition will contribute positively to the national economy as the renewable energy industry is expected to generate 2.5 times to 3.0 times more jobs per dollar of investment compared to fossil fuel technologies. .

TNB, after evaluating its 10-year development strategy, has targeted the push towards a low carbon economy by increasing its renewable energy capacity to 8,300MW by 2025, including large hydropower projects. At the end of 2020, TNB achieved 3,398.2 MW of renewable energy, of which 2,732.3 MW within Malaysia and 665.9 MW internationally.

Besides generating electricity, the Nenggiri Dam project will support Kelantan in a number of areas, primarily in terms of flood mitigation and clean water supply, as well as electricity for rural areas, social infrastructure, and local employment opportunities.

Heavy rains and tides during the northeast monsoon months from November to February have always caused great suffering to lowland Kelantan residents as a result of the devastating floods, as well as the financial burden on the state government.

Since the Nenggiri Dam plays a multi-pronged role in mitigating floods, providing clean water along with generating power, this will not only benefit the river fishermen downstream but also the badai farmers who depend on irrigation canals. – Bernama
