Context
Ministry of Power issued an order for extension of the waiver of Inter-State Transmission system (ISTS) charges on the transmission of electricity generated from solar and wind sources.
About the ISTS waiver
- Inter-State Transmission system (ISTS) is an intra-State transmission system, which is used for the conveyance of electricity across the territory of an intervening State as well as conveyance within the State.
- The ISTS waiver has been extended till 30th June 2025.
- The waiver was earlier available till 30th June 2023.
- Significance: It will promote the development of solar, wind, Hydro Pumped Storage Plant (PSP) and Battery Energy Storage systems (BESS), the trading of RE in the power exchanges, and the seamless transmission of RE power across the states.
- This is expected to encourage the RE trade in the Power Exchanges.
- The buyers of Renewable energy will also have an opportunity to sell their surplus power in the power exchanges or allow in advance the sellers to sell in the power exchange.
- It also allows the waiver of transmission charges for RE trade in the Green Day head Market (as part of the integrated Day-ahead market).
- It paves way for an energy transition from Fossil fuel to Non-fossil fuel by giving incentive for power trade from Renewable, Hydro PSP, and Energy Storage.
- This amendment Order will be a boost to renewable energy.
- It is a step forward to achieve the targets of the Government of India in meeting the international obligations towards climate change.
Green Day head Market
- India is set to have an integrated day-ahead market for conventional electricity and renewable energy.
- It will allow green plants to have 2 options to sell their power.
- The day-ahead market is an electricity trading market for next-day delivery.
- This would help in green electricity purchases in a short period.
- CERC, POSOCO, and the power exchanges are working on it.
- It will be operationalized from August 2021.
Other markets for power purchase
- Day-ahead market
- Term ahead market
- Real-time market
- REC market
