Quick Facts
What bankable EPC means
A bankable EPC is a solar Engineering, Procurement, and Construction contractor whose participation in a project gives lenders sufficient confidence to provide non-recourse project finance. The term reflects a lender’s assessment, not a formal certification or industry standard.
Project finance is structured so that the loan is repaid from the project’s cash flows, with the project assets as collateral, not the parent developer’s balance sheet. Lenders therefore need confidence that the project will be built as designed, perform per projections, and operate reliably for the loan term. The EPC contractor’s capability and reliability are central to this confidence.
A bankable EPC reduces lender risk in several ways: by ensuring the project is built correctly the first time, by standing behind performance guarantees with credible financial backing, and by providing post-commissioning support if issues arise.
For Indian solar projects above approximately Rs 50 crore (or 5 MW capacity), bankability is a critical EPC qualification. Below this threshold, self-financed CAPEX projects may use non-bankable EPCs as long as the customer is comfortable with the trade-off.
What makes an EPC bankable
Lenders evaluate EPCs against several dimensions.
Financial strength: Positive net worth, profitable operations, manageable debt levels, audited financial statements. The EPC must be financially capable of standing behind warranties and performance guarantees for 5 to 10 years.
Project track record: Completed projects of comparable scale and complexity. Lenders typically require 5+ years of EPC experience and a demonstrated portfolio of completed projects in the relevant segment (utility-scale, rooftop commercial, etc.).
Technical capability: Qualified engineering team, design competence, supply chain management, construction expertise, commissioning capability. ISO 9001 certification is a baseline indicator.
Warranty and performance support: Track record of honoring warranties on past projects, ability to dispatch service teams, spare parts inventory, and financial backing for warranty claims.
Key personnel: Experienced project managers, engineers, and senior management who have delivered similar projects. Lender’s technical advisor often interviews key personnel.
Regulatory standing: ALMM compliance for projects requiring it, BIS certifications, MNRE empanelment, ISO certifications.
Insurance: Ability to secure all-risk insurance, performance bonds, and professional indemnity coverage from established carriers.
Litigation history: Material legal disputes affect bankability. Clean legal history supports bankability.
How EPCs build bankability
For new or growing EPC contractors, bankability is built over years through:
Initial projects with self-financed CAPEX customers (no lender qualification needed).
Smaller lender-financed projects with strong project structures.
Progressive scale-up to larger projects.
Building track record portfolio of successfully completed projects.
Maintaining strong financials and proper governance.
Achieving ISO 9001 certification with genuine implementation.
Hiring experienced senior staff with project finance background.
Building relationships with lenders, lender’s technical advisors, and developer customers.
The path takes 3 to 5 years typically. Major Indian EPCs that are now widely bankable (Sterling and Wilson, Tata Power Solar, Adani Solar EPC, Mahindra Susten, Mytrah Solar, Sun Power Renewable, IBC Solar) followed similar trajectories.
Bankable EPC qualification in typical RFP
Large solar projects, especially utility-scale and large commercial, include EPC qualification criteria such as:
Minimum 5 to 10 years of EPC experience.
Minimum installed capacity of 10 to 100 MW depending on project size.
ISO 9001 certified.
Audited financial statements with positive net worth.
No material litigation in the past 3 years.
Insurance arrangements with established carriers.
Key personnel CV requirements (project manager, lead engineer).
Successful similar projects with named references.
Bid security and performance guarantee.
The qualification is binary at the bid stage: meet the criteria or not. Within qualified bidders, lender’s due diligence further evaluates bankability.
Indian EPC bankability landscape in 2026
Several Indian EPC contractors are widely bankable across Indian and international markets:
Sterling and Wilson (Shapoorji Pallonji group): Among the world’s largest solar EPC contractors. Multi-country presence.
Tata Power Solar EPC: Tata Group’s solar EPC arm. Strong domestic and growing international presence.
Adani Solar EPC: Part of Adani’s broader solar business. Strong utility-scale presence.
Sun Power Renewable: Mid-large Indian EPC with growing international footprint.
Mahindra Susten: Mahindra Group’s solar EPC arm.
IBC Solar: India-Germany joint venture, strong rooftop and commercial presence.
Mytrah Solar (now part of larger group): Established commercial and utility EPC.
CleanMax EPC: Captive EPC for CleanMax’s own projects.
Vikram Solar EPC: Solar manufacturer’s own EPC arm.
Several smaller and regional EPCs serve specific markets and segments.
Bankable EPC versus turnkey EPC
Turnkey EPC: A contractor that handles the entire project (design, procurement, construction, commissioning), delivering a fully functional plant to the customer. Focus is on scope.
Bankable EPC: A contractor acceptable to lenders for project finance. Focus is on lender confidence.
The two overlap but are not identical:
Most bankable EPCs are also turnkey (lenders typically prefer turnkey for risk allocation reasons).
Some turnkey EPCs are not bankable (they handle full scope but lack the financial strength or track record for lender acceptance).
Bankable EPC scope can be turnkey or specific (design only, procurement only) depending on project structure.
For most lender-financed projects, bankable turnkey EPC is the standard structure.
Performance liquidated damages (LD)
A bankable EPC contract typically includes performance LD provisions:
The EPC guarantees specific performance metrics (PR, CUF, availability).
Failure to meet the guarantees triggers monetary penalty (the LD) to the project owner.
LD provisions provide concrete remedy for performance shortfall, supporting lender confidence.
LD amounts are typically expressed as Rs per unit of underperformance per year, capped at a percentage of the EPC contract value.
The LD mechanism is a critical bankability feature. Lenders evaluate the EPC’s ability to honor LD payments as part of bankability assessment.
Common bankable EPC mistakes
Treating ISO 9001 certification as sufficient for bankability. ISO 9001 is necessary but not sufficient; other factors matter equally.
Choosing EPC purely on price without considering bankability. Lower-cost EPCs may not deliver lender-acceptable execution.
Ignoring EPC’s financial position. Track record from 3 years ago does not guarantee current financial health.
Skipping reference checks. Past customers reveal actual EPC performance.
Mismatching EPC scale to project size. A small EPC may not have capacity for a large project, even if technically capable.
Best practices
For lender-financed projects: Confirm EPC bankability with the lender before signing contracts. Some lenders maintain pre-approved EPC lists.
For comprehensive EPC evaluation: Use multiple criteria (financial, technical, track record, references, insurance) rather than relying on single indicators.
For new or smaller EPC consideration: Add risk mitigation through performance bonds, stronger LD provisions, and milestone-based payments.
For long-term operations: Verify EPC’s O&M capability and willingness to honor warranties through the project life.
For multi-site portfolios: Consider single bankable EPC for portfolio consistency, or multiple EPCs for risk diversification.
Standards and references
Bankability is a lender-specific assessment without formal certification. Indicators include ISO 9001 certification, ALMM module compliance, BIS certifications, financial reporting per Indian accounting standards (Ind AS), and insurance from IRDAI-licensed carriers. Lender’s technical advisors evaluate bankability through document review, site visits, and reference checks.

Key takeaways
A bankable EPC is a solar Engineering, Procurement, and Construction contractor that lenders accept as the executor of a project under non-recourse project finance. Bankability is built over years through financial strength, project track record, technical capability, warranty support, and experienced personnel. Major Indian bankable EPCs include Sterling and Wilson, Tata Power Solar, Adani Solar, Mahindra Susten, and Mytrah Solar. For self-financed CAPEX projects, bankability is preferred but not strictly required. For lender-financed projects, bankable EPC is a baseline qualification.
