Arbitration Involving Solar Park Epc Issues
đź“Ś I. Key Arbitration Issues in Solar EPC Contracts
Solar EPC contracts — especially for large utility projects like solar parks — routinely include arbitration clauses to resolve disputes arising from:
Delayed commissioning
Performance shortfalls (e.g., energy generation below warranty)
Liquidated damages
Termination disputes
Interpretation of contract clauses
Liability allocation between multiple contractors / suppliers
Because these projects involve high CAPEX, technical execution risk, and complex interfaces (EPC, PPA, land issues), arbitration — either international (ICC, UNCITRAL) or domestic — is preferred for speed, confidentiality, and specialist adjudication.
🧠II. Arbitration in Context of Solar Power and EPC
Under Indian law (Arbitration & Conciliation Act, 1996):
A valid arbitration agreement generally compels courts and tribunals to refer disputes to arbitration under Section 8 if a party invokes it.
However, in regulated sectors like power, statutory bodies such as the Central Electricity Regulatory Commission (CERC) also have a role under Section 79 of the Electricity Act, 2003 — and disputes may require referral by CERC when regulatory adjudication is implicated.
Case authorities help illustrate how this plays out in practice.
đź“ś III. Six Case Laws on Arbitration Involving Solar / EPC Issues
1. Renew Wind Energy (AP2) Pvt. Ltd. v. Solar Energy Corporation of India (2025)
Court: Delhi High Court
Issue: Whether a Section 9 petition under the Arbitration Act is maintainable when a dispute arises under a Power Purchase Agreement (PPA) with an arbitration clause.
Held: The Court dismissed a Section 9 petition, stressing that under Section 79(1)(f) of the Electricity Act, 2003, CERC has exclusive powers to refer such disputes to arbitration if a valid arbitration clause exists.
Principle: In power sector disputes linked to tariff and generation, the statutory scheme may require CERC involvement even where there is an arbitration clause.
Key Point: Jurisdictional authority (CERC) matters for arbitration initiation when regulatory elements are present.
2. Gujarat High Court — TPREL v. Gujarat Power Corporation Ltd. (2023)
Court: Gujarat High Court
Issue: Dispute between a solar power generator and a solar park developer over delays and infrastructure deficiencies.
Held: The Court held that adjudication by the State Electricity Regulatory Commission (GERC) was not appropriate and directed appointment of an independent arbitrator as per the EPC/Implementation and Support Agreement.
Principle: Even where regulatory commissions exist, if contractual obligations between developers and contractors fall outside distribution license disputes, arbitration clauses prevail.
Significance: Clarifies scope of arbitration in developer‑to‑developer disputes over EPC performance and delivery.
3. Shriram EPC Ltd. v. Rioglass Solar SA (ICC Arbitration Award & Enforcement)
Court: Madras High Court
Issue: Enforcement and challenge of a foreign ICC‑seated arbitration award in an EPC contract for supply to a solar/thermal project.
Held: The court affirmed that:
The arbitration was international with London seat,
Indian courts lack jurisdiction under Part I of the Arbitration Act to entertain a Section 34 challenge to a foreign‑seated award, applying BALCO principles.
Enforcement under Section 47 was appropriate.
Principle: Foreign‑seated arbitration awards in solar/EPC contexts cannot be set aside in Indian courts under Section 34 if the seat is abroad.
Significance: Emphasises seat selection impact and enforcement regime.
4. Saisudhir Energy Ltd. v. NTPC Vidyut Vyapar Nigam Ltd. (2026, Supreme Court Of India)
Court: Supreme Court of India
Issue: The extent of judicial interference with arbitration awards in a solar PPA/EPC enforcement context — specifically about delayed commissioning and related liquidated damages.
Held: The Supreme Court restored a ₹27 crore award for delayed solar project commissioning, emphasizing limits on appellate re‑calculation under Sections 34 & 37 of the Arbitration Act.
Principle: Once an arbitral finding stands, courts have limited power to re‑work damages if the interpretation is possible on record.
Significance: Sets clarifying boundaries for interference in arbitration related to solar/EPC project delays.
5. Saisudhir Energy Ltd. v. NTPC VV (2016 and subsequent appeals) (Earlier stages)
Court: Delhi High Court (earlier stage of above dispute)
Issue: Delay in commissioning under solar PPA and invocation of arbitration clause.
Held: The High Court granted liquidated damages which later were partly modified; subsequent appeals moved to Supreme Court.
Principle: Arbitration clauses in PPAs/EPCs are enforceable for delay disputes and tribunals can award damages even in project contracts for public utilities.
Significance: Demonstrates trend of referral to arbitration in solar EPC / PPA disputes.
6. Arbitrations in Solar Module / EPC Performance Issues (Illustrative / Industry Arbitration Practice)
Although not always reported in mainstream law reports due to confidentiality, industry practice shows repeated arbitration in solar EPC contexts for performance disputes such as:
Under‑performance of solar modules under warranty,
Performance degradation claims where energy output fails contractual thresholds, and
Liability for equipment defects vs. installation failures.
Principle: Tribunals routinely allocate liability based on warranties, performance guarantees, and technical evidence where EPC integration issues cause losses.
đź“Ś IV. Practical Takeaways for Solar EPC Arbitration
| Issue | Arbitration Treatment |
|---|---|
| Delayed Commissioning / Liquidated Damages | Enforced through arbitration / tribunal awards; courts reluctant to re‑work valid awards. |
| Regulatory vs. Contractual Dispute | If regulatory elements involved, statutory bodies like CERC may have referral powers. |
| Foreign‑seated Arbitration | Indian courts defer to foreign seat jurisdiction and enforce awards under Part II only. |
| Multi‑Party / Multi‑Contract Complexities | Arbitration clauses and impleader issues require careful drafting and tribunal jurisdiction planning. |
| Performance Guarantees / Technical Defects | Arbitrators frequently resolve disputes based on technical evidence and contractual warranty language. |
đź“Ť Conclusion
Arbitration in solar park/EPC contexts is now a well‑trodden route for resolving disputes over delays, performance, enforcement of awards, and jurisdiction. While courts support arbitration clauses strongly, specific statutory overlay (like the Electricity Act) and choice of seat can materially affect process and outcome. The case laws above provide a cross‑section of how Indian courts and tribunals treat arbitration relating to solar power projects.
