To meet these targets and reach sustainability status the GOI set up certain policy & Regulatory
measures along with incentivizing the sector through exemptions.
Chief Policy and Regulatory Framework of JNNSM are:
? Amendment of National Tariff Policy for solar specific RPOs
?
Solar specifi RPO – 0.25% in Phase 1 (2013) to increase to 3% by 2022
?
REC Mechanism
?
Encourage state specific solar policies
?
State-wise RPO Orders by Regulators
?
Exemption from environmental clearance for solar power projects
The Requirement of Solar power capacity by 2017 is estimated to be about 10000 MW. (See table 4)
This requirement is expected to reach 30,000 MW by 2022.
Solar power generation technologies
Bulk generation of power utilizing solar energy is primarily achieved via two methods:
1. Photo-Voltaic (PV)
2. Concentrated Solar Power (CSP)
In Photovoltaic (PV) based, application's a part of
solar energy is directly converted to electricity
utilizing the photovoltaic cells. A PV based power
generation system with parts is in Figure 9).
Thin film and Crystalline cells are solar energy is
primarily achieved via two types of PV module
technologies.
Major benefits of PV technology over
CSP are:
-Modular and scalable
-Less sensitive to hot climates
-No water or heating fluid need.
-Low gestation period for project to come online

In Concentrated Solar Power (CSP) or thermal
´
application, solar energy is concentrated and converted to thermal energy, heating up a process fluid, ñ
and raising the mechanical energy, that is then converted to electricity by turbines. (See Fig 10)

CSPs generation project have higher gestation time, and maintenance issues in different formats of
Š
CSP available are:
-Parabolic Troughs (Mostly used: 88% of world CSP is through parabolic troughs)

-Parabolic Dishes with Sterling Engine

-Central receivers/towers

The ambitious targets set ably supported by regulatory measures & guidelines could go a long way in

-Fresnel Concentrators (Second mostly used method in India)
India reaching the goals. Choice of technologies, capacity allocation for them in each phase,
differentiated gestation periods along with spelling out domestic content extent & specifics have been
stipulated to avoid ambiguity.
