Lecture to NTPC Senior Management, Lonavla, 11 June 2016

Renewable Energy Technology for the

Power sector: Status and Future

What is Renewable Energy?

I) Energy that is available naturallyII) Energy that does not result in carbon dioxide

emissionsIII) Energy that has no losses of conversionIV) All of the aboveV) None of the above

2

Which of the following is true?

I) Coal and oil are sources of renewable energy

II) Hydrogen energy is renewableIII) Fission based nuclear energy is renewableIV) More than one of the above optionsV) None of the above

Give reasons

Carbon Dioxide Emissions

Kaya identity: Total CO2 Emissions

= (CO2/E)(E/GDP)(GDP/Pop)Pop

CO2/E – Carbon Intensity

E/GDP- Energy Intensity of Economy

Mitigation – increase sinks, reduce sources- aforestation, fuel mix,energy efficiency, renewables,nuclear, carbon sequestration

Overall

Specialisation- Sub Tasks – Difficult from scratch

1 MW – too small for CSP with present route

Industry interest in CSP research – declined- change in priorities-

budgets

Catalysed CSP development – few consortium partners

Testing of one concentrator, new HTF fluid

Simulator – Evaluation licenses-Tata Power, Fichtner

For profit company – Solar Home systems –

started 1996 – sold about 100,000 SHS

90% of products – credit schemes

Partnership with 9 banks – interest rates

between 12-17%

Financing Institutions pay 85% of the

amount- monthly payments of Rs 300- 400

over a period of 5 years

Financing/ repayment options – tailormade

to end users – paddy farmers – repayment

schedule based on crop cycle, street vendors

– daily payments – Rs 10

Funding from REEP – meet margin amount

for poor customers, reduce interest rate
