1. Solar Parks Concept: Solar Energy in India by:
• Decreasing the costs of development,
• Facilitating the due diligences of Solar projects with
financial institutions,
• Increasing the bankability of Solar projects in India and
• Decreasing the cost of generation targeting grid parity.

• Step 2 has been carried out on immediate basis since proposed assets have
relatively longer construction periods and immediate procurement decisions
are required in order to facilitate the planned RES integration by 2022
(concluded)
• Step 3 involves detailed analysis of the power system to characterise,
understand and define the diagnostic of the power system, find out
weakness and key operative and equipment (installation of Voltage
regulation devices etc.) needs. These equipments have shorter procurement
and installation periods (on-going)Outcome: Recommendations and guidelines for improvement of operation planning of the system with large RES

• Development of an integrated PSSE model of the Power system:
• Integration of RVPN and POSOCO models ;
• Integration of the proposed future facilities and demand 2021-22
• Execution of simulations and Analysis of results:
• Operative scenarios in different operative conditions (generation,
export, demand).
• Analysis of the performance of the facilities under the alternative
scenarios
Analysis: Scenario X
