MNRE Issues Guidelines for Bidding Process for Wind-Solar Hybrid Projects

MNRE has issued draft guidelines for the tariff-based competitive bidding process for the procurement of power from wind-solar hybrid projects.

Wind Solar Hybrid Guidelines

The Ministry of New and Renewable Energy (MNRE) has issued a draft of the guidelines for the tariff-based competitive bidding process for the procurement of power from grid-connected wind-solar hybrid projects.

The Ministry had in 2018 issued a Wind-Solar Hybrid Policy with the objective to provide a framework for the promotion of such large scale projects. The policy aimed to provide a system for optimal and efficient utilisation of transmission infrastructure and land, reducing the variability in renewable power generation and achieving better grid stability.

And now, in order to provide a framework for the transparent bidding process, as required under Section 63 of the Electricity Act 2003, the ministry has issued the draft guidelines. The draft has been opened to comments and suggestions from stakeholders with a deadline of October 31, 2019, after which the guidelines will be officially introduced.

As per the draft, one of the objectives of the guidelines is to enable Discoms to procure electricity from wind-solar hybrid power project at competitive rates in a cost-effective manner.

Key Points:

  • The guidelines have been issued for hybrid projects of at least 5 MW at one site with the minimum bid capacity of 25 MW for intra-state projects; and individual size of at least 50 MW at one site with the minimum bid capacity of 50 MW for inter-state projects.
  • The guidelines allow the storage component to be added to hybrid projects to curtail the variability of power. Bidders would be selected on the basis of the lowest quoted tariff bids (per kWh) for power purchase agreements (PPA) of a minimum period of 25 years. Like solar and wind projects, hybrid renewable projects will also be awarded on the basis of an e-reverse auction.
  • Procurers looking to buy electricity from hybrid projects would be mandated to provide for adequate payment security measures in order to protect the interest of the generators. This would be done through a revolving letter of credit (LC), payment security fund, and state government guarantees.
  • And, the financial closure timelines for wind-solar hybrid projects would be seven months from the date of signing of the PPAs. Furthermore, the successful bidders would be given 18 months to commission projects from the same date.

In September, Rajasthan came up with its draft solar-wind hybrid policy that aims to achieve 2000 MW Wind Power capacity. The target is set for the fulfillment of Renewable Purchase Obligation (RPO) of State Discoms in respect of wind energy as determined by the Rajasthan Electricity Regulatory Commission (RERC) up to 2023-24.
