The grid support charges as determined by the Commission in the tariff orders from time to time shall be applicable.
Guidelines for tariff based competitive bidding process for procurement of firm and dispatchable power from grid connected renewable energy power projects with energy storage systems
- The Ministry of Power (MoP) issued the Guidelines for tariff based competitive bidding process for procurement of firm and dispatchable power from grid connected renewable energy power projects with energy storage systems, dated June 9, 2023 (Bidding Guidelines).
- The Bidding Guidelines have been issued with the following
- To provide firm and dispatchable power to the DISCOMs from renewable energy sources
- To facilitate renewable capacity addition and fulfilment of Renewable Purchase Obligation (RPO)/ Storage Power Obligations (SPO) requirement of DISCOMs
- To provide a transparent, fair, standardized procurement framework based on open competitive bidding with appropriate risk-sharing between various stakeholders to enable procurement of power at competitive prices in consumer interest, improve bankability of projects and ensure reasonable returns to the investors
- To provide a framework for the inter-State/intra-State, long-term, sale-purchase of power as a further measure to de-risk the sector
- These Bidding Guidelines apply to long-term procurement of firm and dispatchable power by procurers, such as DISCOMs, from renewable power projects through competitive bidding. This ensures that the procurement process aligns with the provisions of Section 63 of the Electricity Act, 2003 as the Bidding Guidelines provide parameters and structure that bidding documents and process must follow.
Amendments to APERC Renewable Power Purchase Obligation (Compliance by Purchase of Renewable Energy/Renewable Energy Certificates) Regulations, 2022

Clarifications on Karnataka Electricity Regulatory Commission (Terms and Conditions for Green Energy Open Access (GEOA) Regulations, 2022
- The Karnataka Electricity Regulatory Commission
(KERC) has issued a clarification to the KERC
(Terms and Conditions for Green Energy Open Access, Regulations,
2022 (GEOA Regulations). Key aspects:
- Implementation of Time of Day (TOD) settlement of energy injected/drawn: KERC has clarified that in line with the methodology developed by Forum of Regulators (FOR), 2% of the banked energy in kind in addition to the 8% banking charges should be charged for drawl of off-peak energy during peak hours. The TOD slots shall be as specified in the tariff orders issued from time to time and shall be applicable to low tension consumers also who seek open access under the KERC GEOA Regulations. The morning peak slot shall be from 06:00 HRS to 10:00 HRS and the evening peak slot shall be from 18:00 HRS to 22:00 HRS, unless it is modified.
- Settlement priority between different generation sources: KERC has clarified that interState transactions shall be given priority under existing Clause 6.1.3 of Wheeling Banking Agreement (WBA) under the KERC (Terms and Conditions for Open Access) Regulations. In case, the consumer buys power under the old regime as well as under the new regime of the GEOA, the energy should be allocated on pro-rata basis of the contracted capacity under different regime, till such time the generating units which come under GEOA provide separate meters so that they can be treated separately for energy accounting purpose. Further, while billing the energy under GEOA should be settled first followed by settlement of energy under old regime, with annual banking.
- Charges to be paid by new consumers to be added to an existing WBA (signed before issue of the GEOA Regulations): KERC clarified that any generator can add or delete consumers under the existing WBA. As far as the open access charges are concerned for these new consumers and for any capacity addition by existing addition by existing consumers under the old WBA regime, the charges in terms of GEOA must be paid as the GEOA Regulations are applicable to all consumers who seek open access after coming into effect of the GEOA Regulations.
- Applicability of transmission charges for intra-State
wheeling of energy: KERC has clarified that in case the
wheeling of energy involves usage of transmission network or
network of more than one licensee, the charges shall be as
- If only transmission network is used, transmission charges including losses determined by KERC shall be as payable to the transmission licensee;
- If the transmission network and the DISCOMs network is used, transmission charges shall be payable to the transmission licensee, in addition to transmission and DISCOMs technical losses and wheeling charges shall be payable to the DISCOM where the power is drawn. Wheeling charges of the DISCOM where the power is drawn shall be shared equally among the DISCOMs whose networks are used.
- If DISCOMs network only is used, after deducting the DISCOMs technical loss of the wheeling charges of the DISCOM where the power is drawn is payable and shall be shared equally among the DISCOMs whose networks are used.
- Charges applicable under the GEOA Regulations:
Till KERC adopts and determines the charges in accordance with the
methodology specified by FOR, Karnataka Transmission Company Ltd/
State Load Dispatch Centre/ DISCOMs are directed to collect the
- The transmission charges along with the transmission losses as determined by the KERC in its tariff order shall also be applicable for all transactions coming under GEOA Rules.
- Wheeling charges, wheeling losses, additional surcharge, and cross subsidy surcharge in full, as determined by the KERC in its tariff orders issued from time to time.
- Standby charges as per the GEOA Rules specified by Ministry of Power.
- Banking charges as specified by FOR (8% of the banked energy).
