Settlement mechanism implemented only after ERC and WESM Governance Arm approval.
TAKEAWAY
Generation companies and DUs should prepare to participate by ensuring compliance with eligibility, documentation, and technical requirements.
Stakeholders must monitor DOE and ERC issuances for auction schedules, GAT Price, and settlement mechanism implementation.
KEY POINTS
Scope: Applies to Natural Gas Power Generation Companies, Transco, NEA, System Operator, Market Operator, WESM Governance Arm, Transmission Network Providers, Distribution Utilities, and electricity end-users as applicable.
Requirement: Competitive auction mechanism for procurement of mid-merit natural gas-fired power generation capacity, covering new, expanded/upgraded, and existing uncommitted facilities registered in WESM.
Thresholds: Auction Capacity and Gas Auction Threshold (GAT) Price set per round; GAT Price determined and published by ERC as the price ceiling; bids above GAT Price are disqualified.
Deadlines: ERC to issue initial GAT Price and methodology within 60 days of Invitation to Bid (ITB) for first round, and within 30 days for subsequent rounds; Terms of Reference and Guidelines issued at least 15 days before registration; post-auction compliance and document submission required as specified in TOR.
Covered Entities: Qualified Bidders (generation companies), DUs with uncontracted mid-merit requirements, and relevant government agencies (DOE, ERC, Transco, NEA, Market Operator, WESM Governance Arm).
Compliance Obligations: Winning Bidders must deliver awarded capacity by the committed Delivery Date, comply with settlement, reporting, and regulatory requirements, and maintain declared fuel source category; DUs included in Auction Capacity are bound to accept and comply for the delivery period.
Mechanisms Introduced/Amended:
Centralized auction process with priority stacking for indigenous, blended, and non-indigenous gas.
Fuel Cost Pass-Through mechanism subject to ERC benchmarking and audit.
Carve-Out Mechanism for DUs affected by customer migration to competitive retail market.
Option for Winning Bidders to finance and construct Associated Transmission Projects if needed.
Settlement through WESM with defined formulas for shortfall collection and flowback.
Prohibited Acts: Failure to deliver awarded capacity, withdrawal by DUs, bid manipulation, anti-competitive conduct, fuel source misrepresentation, and unjustified fuel cost pass-through, subject to penalties under EPIRA and exclusion from future auctions.
Implementation: DOE to conduct auctions as needed; effectivity upon publication; settlement mechanism requires ERC approval and WESM system certification before full implementation.
