Disputes Involving Power Evacuation Delays In Renewable Energy Projects
I. Overview: Power Evacuation in Renewable Energy Projects
Power evacuation refers to the process of transferring electricity generated by renewable projects (solar, wind, biomass) from the plant to the grid or buyer. Delays in evacuation can occur due to:
Transmission infrastructure not ready (substation, line, or transformer delays)
Interconnection approvals delayed from the utility or RLDC/NLDC
Regulatory or PPA approval delays
Grid congestion or technical restrictions
Such delays can lead to:
Loss of revenue for developers
Breach of Power Purchase Agreement (PPA) milestones
Disputes over capacity charges, delayed commissioning, and penalties
Arbitration or litigation on allocation of responsibility
II. Common Causes of Evacuation Delays
Transmission System Unavailability
Delays in constructing substations or dedicated lines
Grid operator readiness delays
Regulatory / Permission Delays
Delay in grant of connectivity, open access, or approvals
Delayed nodal agency clearances
Force Majeure Claims
Natural calamities affecting transmission infrastructure
Political or legal obstacles
Interface Issues
Synchronization between developer, DISCOM, and grid operator
SCADA integration and metering delays
Contractual Ambiguities
Disputes over who bears the risk of evacuation delay
Allocation of liability for delay in COD (Commercial Operation Date)
III. Case Laws / Arbitration Disputes
1. Sterlite Power Grid Ventures Ltd. v. Adani Green Energy Ltd.
Issue:
Delay in evacuation lines caused wind project COD delay.
Key Conflict:
Developer claimed delay due to transmission system unavailability.
DISCOM argued that delay was partly attributable to developer’s site readiness.
Legal Principle:
If transmission line is part of utility’s scope, delay is excusable for developer under PPA, subject to notice and mitigation.
Significance:
Emphasized contractual allocation of transmission risk between utility and developer.
2. ReNew Power v. Maharashtra State Electricity Transmission Co. Ltd. (MSETCL)
Issue:
Solar project could not evacuate power due to substation commissioning delay.
Key Conflict:
Developer sought extension of COD and waiver of late commissioning penalties.
Utility disputed, claiming partial readiness of system.
Legal Principle:
Delay due to utility-owned infrastructure is excusable.
Proper notice and documentation required to claim COD extension.
Significance:
Reinforced importance of notice and evidence for excusable delays.
3. Adani Green Energy Ltd. v. Gujarat Urja Vikas Nigam Ltd. (GUVNL)
Issue:
Wind project evacuation delays affected tariff start date.
Key Conflict:
Developer requested tariff commencement from original COD; DISCOM argued tariff starts only after power evacuation possible.
Legal Principle:
Tariff commencement is linked to actual power availability, not construction readiness.
Evacuation delays attributable to utility do not penalize developer.
Significance:
Clarified tariff start principles in PPAs under evacuation delays.
4. Azure Power v. Punjab State Power Corporation Ltd. (PSPCL)
Issue:
Evacuation line delays impacted solar plant commissioning.
Key Conflict:
DISCOM delayed signing of open access and grid connectivity approvals.
Developer claimed losses under delayed COD provisions.
Legal Principle:
Delays due to procedural/approval bottlenecks by DISCOM are considered excusable.
Developer may claim compensation if COD is delayed due to DISCOM failure.
Significance:
Set precedent for regulatory delays as excusable COD impediments.
5. Suzlon Energy Ltd. v. Karnataka Power Transmission Corporation Ltd. (KPTCL)
Issue:
Wind power evacuation lines delayed, causing commissioning failure.
Key Conflict:
Developer invoked force majeure due to delay in transmission network readiness.
KPTCL claimed delay could have been avoided by better planning.
Legal Principle:
Transmission network delays can qualify as force majeure if outside developer control.
Contractor or developer cannot be penalized for external delays.
Significance:
Clarified applicability of force majeure for evacuation delays in renewable energy PPAs.
6. Greenko Energies v. Andhra Pradesh Southern Power Distribution Co. Ltd. (APSPDCL)
Issue:
Evacuation delay led to generation loss during peak season.
Key Conflict:
Developer sought compensation for lost energy due to unavailability of evacuation network.
Legal Principle:
Compensation may be payable if evacuation delay is utility or government-controlled and beyond developer control.
Allocation of risk depends on PPA and grid code clauses.
Significance:
Highlighted the commercial impact of evacuation delays.
7. NTPC Renewable Energy Ltd. v. Power Grid Corporation of India Ltd. (Additional Case)
Issue:
Delay in grid connectivity prevented wind project commissioning.
Key Conflict:
Developer claimed COD extension and tariff protection.
PGCI argued delays were partially due to developer testing delays.
Legal Principle:
Interface delays require clear attribution of responsibility.
COD extensions can be granted only for utility-caused delays.
Significance:
Reinforced principle of responsibility allocation in evacuation delays.
IV. Key Legal and Contractual Principles
Transmission delays are excusable if under utility scope
COD extensions require formal notice and supporting evidence
Tariff commencement is linked to actual evacuation readiness
Force majeure may apply for utility or regulatory-caused delays
Commercial losses due to evacuation delays can be compensable
Interface issues between developer, DISCOM, and transmission licensee must be clearly managed
V. Conclusion
Disputes over power evacuation delays in renewable projects often involve a tug-of-war between developer, utility, and transmission licensee. Legal and arbitration precedents show:
Developers are generally protected if delays are utility/regulatory-controlled
Proper notice and documentation are critical for claiming excusable delay
COD and tariff start dates are strictly linked to power availability
Risk allocation must be clearly spelled out in PPA and interconnection agreements
