Green Renewal Power

RTS(Rooftop Solar), Waste to energy and Bio Gas projects (in that order), need to be promoted India has achieved target for Solar PV power,mainly due to larger captive solar parks However captive solar takes away agricultural land while RTS, uses existing roof over CHS, does not need acquisition of land

India blessed with 300 days of sun in a year: Unlike countries in Europe, Americas, almost all parts of India get more than 300 days of full solar radiation, ie four hours or more. Thus India is blessed with abundant renewable, green, solar power India need not depend upon fossil fuels or even expensive nuclear to meet our growing energy demands.

Rooftop Solar(RTS) PV panel generates power during the day , to meet peak demand from industries while the resident user, will be drawing from the grid in night when power demand is low This is ideal for meeting variation in electrical energy ie peak load demands during 11 AM to 3 PM. Thus renewable electricity from solar PV can ideally meet peak load requirements while non renewable electricity from coal can meet base load requirements. As per one study, all Mumbai’s power requirements can be met from Roof top solar PV if only 10% of potential is tapped.

Among renewable energy options, capital cost of rooftop solar are a fraction of wind/bio gas Nuclear power does not generate carbon emissions However it is now prohibitory expensive, as compared with Rooftop solar power Nuclear power has longer gestation period as well Unlike for captive solar.

For Roof top solar installation, one does not need to acquire additional land; existing roof area is used to catch solar energy, that was going any way going waste or was heating up the building or causing leakages in rainy season. What is Gross metering(GM) , Net Metering (NM), Grid support charges In both GM ans NM, the solar panel is connected to grid. There is no need of battery back up. Under GM(Gross metering) , the total energy generated by the solar rooftop plant is assumed to be injected into the grid without allowing the generated solar energy to be consumed directly by the consumer. Under NM, the power units generated by the solar rooftop plant is allowed for self-consumption and the excess energy is injected to the grid. Under net metering, the units consumed are set off against unit produced like a barter arrangement In other words, the producer gets set off the production @ rate of power tariffs charged. In case of high users, or commercial establishments, the rate of power tariff rate is Rs 12 per KW-Hr Under NM, the producer gets credit for electricity produced @ Rs 11 per unit.

Under net metering, the excess units used by consumers are credited @ tariff rates of DISCOM, like a barter system . As against this, under gross metering, the producer gets credited , say @ Rs 3 per unit, while their usage is charged say @RS 11 for the power that is consumed.

Thus Gross metering makes solar rooftop projects un viable. Under gross metering, the entire consumption will be charged at DISCOM tariff, and value of solar energy generated by the consumer will be deducted from it @ rate of lowest PPA (power purchase agreement) Grid support charges is back door gross metering as the DISCOM charges Rs. 3 to Rs 8 to solar PV generators In other words, gives them abysmally low rate for power that they produce.
