A state electricity report serves as an important tool to assess energy production and track progress in the power sector. By providing quarterly data on generation measured in gigawatt hours (GWh), the report highlights the contribution of different energy sources such as coal, gas, hydro, solar, and wind. This not only helps in understanding the overall energy mix and dependence on conventional versus renewable sources but also enables policymakers, planners, and stakeholders to evaluate trends, address gaps, and promote sustainable energy development. A state electricity report provides quarterly generation (in GWh) by source – Coal, Gas, Hydro, Solar, and Wind.
In Q1 Generation from Coal is 2,200 GWh, Gas contributes 800 GWh, Hydro 900 GWh, Solar 700 GWh, and Wind 400 GWh, for a total of 5,000 GWh.
In Q2 Coal rises to 2,400 GWh, while Gas dips to 700 GWh; Hydro improves to 1,000 GWh, Solar to 800 GWh, and Wind to 600 GWh, bringing the quarterly total to 5,500 GWh.
In Q3 Coal moderates to 2,100 GWh, Gas increases to 900 GWh, Hydro softens to 800 GWh, but Solar advances to 1,000 GWh and Wind to 700 GWh, keeping the total at 5,500 GWh.
In Q4 Coal moves to 2,300 GWh, Gas to 850 GWh, Hydro to 1,100 GWh, Solar to 900 GWh, and Wind to 850 GWh, for a total of 6,000 GWh.
For analysis, Renewables are taken as Hydro + Solar + Wind. A carbon policy scenario proposes cutting Q4 Coal by 10%, shifting the entire reduction equally into Solar and Wind. (255 words)
The annual Gas: Hydro generation ratio is:
Correct Answer :
65:76
Solution :
Correct Answer: The annual Gas: Hydro generation ratio is 65:76 (Option 2).
To find the annual ratio of Gas to Hydro generation, we need to calculate the total annual generation for both Gas and Hydro across all four quarters (Q1, Q2, Q3, and Q4).
Step 1: Calculate Total Annual Gas Generation
From the given report, the quarterly generation for Gas is:
• Q1 Gas = 800 GWh
• Q2 Gas = 700 GWh
• Q3 Gas = 900 GWh
• Q4 Gas = 850 GWh
Total Annual Gas Generation:
Step 2: Calculate Total Annual Hydro Generation
From the given report, the quarterly generation for Hydro is:
• Q1 Hydro = 900 GWh
• Q2 Hydro = 1,000 GWh
• Q3 Hydro = 800 GWh
• Q4 Hydro = 1,100 GWh
Total Annual Hydro Generation:
Step 3: Determine the Ratio of Gas to Hydro Generation
Dividing both sides by 50 to simplify the ratio:
Thus, the annual Gas to Hydro generation ratio is 65:76.
