Question $5\mathrm{.}9$

A small$-$scale diesel fired power plant has been operating since $2014.$ The energy input through diesel to the plant is $1000$ GJ a day and producing power with an energy equivalent of $400$ GJ $(112$ MWh$).$ The plant is also using CHP to utilize waste of $300$ GJ a day. The emission factor of the coal used for the plant is O$\mathrm{.}7$kg CO$2$eq$/$kWh$.$ The company installed a hydropower plant to replace the diesel$-$fired power plant to contribute to achieve SDG $7$ and SDG $13.$ The emission factor of the hydropower plant O$\mathrm{.}1$kg CO$2$eq$/$kWh only. The operating cost of diesel$-$fired power plant is RM$0\mathrm{.}35$ kWh and for hydropower plant is RM$0\mathrm{.}08$ kWh$.$

a$)$ Analyse the data stated to estimate carbon emission CO$2$eq from the plant when operate diesel plant with booster CHP$.$

b$)$ The data stated analyse to measure the impact of replacing diesel fired power plant by hydropower turbine on the environment in the scale of carbon emission $($CO$2$eq$).$ Present your findings on energy source vs emission $($CO$2$eq$)$ graph.$$

c$)$ Apply power generation efficiency model to evaluate the impact of using hydropower plant system on the economy $($RM$).$ Present your findings on Energy source vs economy $($RM$)$ graph.$$
