What is NSM?

The Jawaharlal Nehru National Solar Mission (JNNSM or NSM) is a mission launched by Government of India on the 11th January, 2010 to promote development of solar energy projects in India.  by the Prime Minister.

The NSM has set the ambitious target of deploying 20,000 MW of grid connected solar power by 2022 is aimed at reducing the cost of solar power generation in the country through (i) long term policy; (ii) large scale deployment goals; (iii) aggressive R&D; and (iv) domestic production of critical raw materials, components and products, as a result to achieve grid tariff parity by 2022.

NSM will create an enabling policy framework to achieve this objective and make India a global leader in solar energy.

NSM was supposed be executed in three phases.

  • Phase 1:  1,000 MW (by 2013)
  • Phase 2:  cumulative 4,000 MW (by 2017)
  • Phase 3:  cumulative 20,000 MW (by 2022)

In the Phase 1 of the Mission, 950 MW solar power projects were selected in two batches (batch-I during 2010-11 and batch-II during 2011-12) through a process of reverse bidding. NTPC Vidyut Vyapar Nigam Limited (NVVN) was appointed as the nodal authority for purchase of power from developers and further sale to distribution utilities/ Discoms after bundling with power from unallocated quota of power from coal based stations of NTPC on equal capacity basis. A total capacity of 420 MW has been commissioned under these batches by the end of Phase-1. In addition, a capacity of 50.5 MW under migration scheme, 88.8 MW under IREDA-GBI scheme and 21.5 MW under old Demonstration scheme has been commissioned, taking the total capacity commissioned to 680.80 MW.

For Phase 2 of NSM, on account of unavailability of conventional power for bundling, the Government has fixed the solar tariff at Rs. 5.45 per unit (Rs. 4.75 per unit if accelerated depreciation is availed) and shall assist the developers by providing Viability Gap Funding to make the solar projects viable at this tariff.

Detailed guidelines for bidding under NSM Phase 2 Batch I is issued by the Government of India on 28th October 2013.


Salient Features

Key Technical & Commercial Considerations


Site Selection

  • As there is no concept of Solar Park under NSM Phase II Batch I and also no support will be given by the Government for the land acquisition, the Project Developer has to identify and select the site suitable for the Project.
  • Parameters such as land availability and costs, solar resource availability, proximity to the grid, water etc have to be considered while evaluating the sites.


Land Acquisition

  • As acquisition of land is the biggest hurdle for the development of projects in India, the same is of utmost importance for the Developer.
  • Suitable land should be identified and finalized (in terms of in-principle agreement or agreement to sale etc) before the submission of bids.


Clearances & Approvals

  • Obtaining all the necessary clearances & approvals are the responsibility of the developer.
  • Hence, the timelines and risks associated with this are required to be considered.


DCR Requirement for 375 MW Projects

  • Developer has to take into consideration the domestic modules while bidding under the DCR Category;
  • Availability of modules, quality, CUF estimation, degradation & warranty aspects etch are required to be considered.


Grid Connectivity

  • In the absence of the Solar Park concept, the cost of developing and maintaining the evacuation systems as well as generation losses on account of down time of the grid have to be taken into consideration.


VGF Disbursement

  • As the VGF to be disbursed over the period of 6 years from project start date; the same should take into account in the financials models of the Project.
  • Further, various political and economical risks associated with the disbursement of VGF shall also be considered while arriving at the biding amount.
  • Delay in disbursement of VGF by the Government will hamper the financials of the Projects.


Off-take Risks

  • Absence of firm mechanism to ensure a match between states willing to buy power at the pre-determined prices and developers’ preference of location for the projects
  • Lack of clarity on how the SECI will ensure the off-take of the power to states across the country that might be willing to buy the power.


Payment Security Mechanism

  • Lack of clarity in terms of how the payment security will be provided by SECI to the developers.
  • The current mechanism of collecting corpus of fund sufficient for 3 months payment is not adequate considering the lower tariff and high amount of upfront equity funding from the developer.

· Further, without the proper payment security mechanism, the banks/FIs will also be hesitant to provide funds at D:E ratio of 70:30.


Tentative Financials


Considering a standard project size of 10 MW (11 MWp), the financials of the Project will look like below based on the assumptions depicted herewith.


¨ Project IRR: 14.7%

¨ Equity IRR: 15.0%


¨ Project NPV: Rs. 8 Crs

¨ Equity NPV: Rs. 5 Crs


¨ Project Payback: 6.6 Years

¨ Equity Payback: 11.4 Years



– CAPEX: Rs. 6.6 Crs/MW

– VGF Percentage: 25% of the Project Cost

– PLF: 19%

– Interest Rate: 13%

– D/E Ratio : 70/30

– Tariff : Rs. 5.45 per Unit (W/o Depreciation Benefits)

– OPEX: Rs. 6 Lacs/MW with 5% annual escalation


Senstivity Analysis

Sensitivity of the change in key variables such as CAPEX, VGF Percentage,  Interest Rate, PLF and OPEX using the radar chart analysis is depicted in the report. 


Key Strategies for Bidding

  • As the individual project size is 10 MW and in multiples thereof, developers shall try to reduce the beta of the bid amount by lower VGF in lowest bids and higher for the highest bids.
  • Hoping the VGF disbursement as per the defined schedule the Developer shall avail cheaper short term financing such as buyer’s credit or bridge loans.
  • As the maximum CUF limit is adequately high, developers may try to maximize the DC filed thereby getting higher generation with relatively lower increase in CAPEX.
