Optimal Power Generation Mix
Natural Gas grid has the potential to revolutionize the power sector in India. While coal plants provide low cost baseload generation, they lack flexibility and cannot economically meet varying load requirements during course of the day. Wärtsilä has commissioned a study to determine the Optimum generation mix for India, where large coal based power plants can be supplemented with gas based distributed power plants for 24x7 power availability in a sustainable manner.
Optimal Power Generation Mix for India
The attached report brings a perspective on optimisation of the Indian power sector on generation & transmission side. The benefits entailed in the proposed idea supports the National Agenda on Sustainability in a big way, apart from strengthening grid reliability for growing India.
The proposed model establishes, that introduction of High Efficiency - High Flexibility - Distributed Power technology in generation mix would offer the following significant benefits that can be readily monetised by the nation.
- Higher efficiency leading to saving of over 6% of primary energy in the power sector
- Carbon emission reduction by over 110 million tonnes per annum in 2017 time frame which could be of the order of 10% of overall emissions from power sector
- Reduction in water consumption by over 470 million cubic meters per annum, enough to meet the water needs of a city like Mumbai
- Reduction in land requirement by over 24000 acres, meaning saving in deforestation and displacement of people of a mid sized town
- Reduction in investment of transmission network to the tune of Rs 12,800 crores in the 12th plan period
- In overall terms, a potential revenue savings of the order of Rs 13,000 crores per year and capital investment saving of up to Rs 38,900 crores in the 12th plan period.
