How POSCO compute ISTS Charges and Losses


You may heard or read the news ISTS solar projects. But did you know what is ISTS stand for and what are Solar projects? So, I did some research on the same and this is what I found.


ISTS Full Form

ISTS is stand for "Inter State Transmission system".


What is ISTS ?

Any system for the conveyance of electricity by means of a main transmission

line from the territory of one State to another State is called ISTS [the definition is given by POSOCO]


What is ISTS based solar project ?

In ISTS-based Solar project, power generated from one state can be transmitted to other states. ISTS, the developers can bid for their choice of project and location anywhere in India. After getting Developers setting up a solar power plant (or park) at the place allocated to them and build electricity transmission lines to the nearest grid network. The voltage at PV inverter’s output point is low, which needs to be stepped up through a pooling substation. And the development of the same is also in developer’s scope. Customers of developers, can purchase power through gird transmission lines.

Most of the PV energy generators did not have to worry about transmission costs or the cost of scheduling.

  • Wind or early solar projects, selling power under feed-in tariff (FIT) to distribution companies (DISCOMs), need only to connect to the grid. Additional transmission costs are not charged from either the generators or the consumers.

  • Open-access consumers buying power using the state grid pay transmission and wheeling charges in INR/ kWh and may see direct benefit of transmission capacity optimization.

  • Most states offer banking facility, and the banked power can be used up to a year. Generator does not need to optimize generation schedule to match demand with supply
