Question DIST, 0.1% HYD, 14.8% Hydro 3.1096 Others 0.10% Solar 0.60% O COAL, 26.3% GAS, 58.8% Gas 42.3096 Coal 53.909 TNB Generation Fuel Mix FY 2009 TNB Generation Fuel Mix FY 2019 Figure 1 TNB Generation Fuel Mix for 2009 and 2019 The two pie charts shown in Figure 1 depict the change in generation fuel mix over the past 10 years, which are extracted from the annual reports of Tenaga Nasional Berhad (TNB) – the national electric power supplier of Malaysia - of financial years 2009 and 2019 respectively. It is observed that there are three main types of fuel used by TNB, which are coal, gas, and hydroelectric power. The usage of gas remains roughly the same over 10 years, a slight decrease from 59% in 2009 to 42% in 2019. Meanwhile, the usage of coal has been expanded greatly, from 26% in 2009 to 54% in 2019. At the same time, the usage of hydroelectric power shrunk from 15% in 2009 to 3% in 2019. Assess the reasons for this drastic change in the generation fuel mix composition from 2009 to 2019. Evaluate whether TNB is still committed to renewable energy based on the data available from their annual reports.

Please Explain Thank you

Answer 1

As the given pie chart shows, Coal is the largest fuel source of power generation in peninsular Malaysia. Usage of coal has been expanded from 26 % in 2009 to 42 % in 2016 and then 53 % in 2019 . From 2016 to 2019 the percentage increase shows a lot much about its popularity . As we know that coal is the cheapest one, thats why it has a big role in the energy mix of most of the countries. 1000MW power plants are more in Malaysia.

Malaysia is rich in natural gas resources. Therefore it is used too much there, mostly in the power sector. 54.3% as per data . The usage of gas decreased as per the demand because usage of coal based power plant came into picture, thats why its mining decrased as per the usage of coal in power plants incresed.

13 % contribution came from hydro power plants in year 2016 , which was 14 % in year 2009 . Which decreased in year 2019 to 3 percent. It is a drastic change, may be due to its production costing is more than coal. Thats why its usage is decreased.

RENEWABLE ENERGY IN Malaysia - Malaysia is amongst the highest potential solar intake because it is located near the equator. Solar power generation is the most popular in the list of RE in Malaysia. Rooftop solar is being popular there.

FUTURE GOALS TOWARDS RENEWABLE ENERGY SOURCES --

Malaysia govt has set a target to achieve higher percentage in the Malaysia energy mix.Renewable energy has 2 % contribution in Malaysia energy mix. Govt has targeted to increase it to 20 % by the year 2025 . In Malaysia solar generation can be brought up to 6500 MW , so large solar scale and rooftop solar became a good choice in Malaysia.

COMMITMENT BY GOVERMENT - After commiting to COP 15 to reduce its carbon emissions by 40 % , Malaysia pledged to reduce carbon emission in country. The country is definitely going to reduce its GHG emission by 45 percent in the upcoming years.
