Questions this guide addresses
- Can a low bid price support actual completion and operation?
- How are land, grid and offtaker risks allocated between the bidder and procuring authority?
- What connects EPC guarantees to long-term operating performance?
Method and verification scope
- Procurement, grid, PPA and cost concepts were checked separately against official IRENA and World Bank material.
- The checklist prioritizes land, grid, currency and localization conditions that could cause disqualification or damage profitability before focusing on the lowest bid.
- The table's ratings indicate the status of factual verification and do not replace country-specific legal review.
01 · Procurement objective
State the procurement objective clearly before setting the bid price
Renewable-energy procurement is not simply a search for the lowest generation cost. Auction design and evaluation criteria depend on the relative priority given to required energy volumes and delivery hours, completion targets, local industry participation, grid stability and fiscal burden.
If objectives are unclear, selecting an aggressively priced bidder may be followed by extensions, renegotiation or failure to reach financial close. Before the tender, the procuring authority should clearly define its objectives, mandatory conditions and the risks to be allocated to market participants.
02 · Resource & land
Turn a promising resource map into a buildable site
Solar irradiation or wind data is the starting point for project economics, but a plant also requires confirmed site-use rights, access roads, terrain and ground conditions, flood and sand or dust risks, and environmental sensitivity. Unclear measurement periods or data-adjustment methods increase uncertainty in long-term generation estimates.
Legal title and the community's actual use of the land may not be resolved by documentary ownership alone. Reviewing land-acquisition timing, livelihood impacts, resettlement and grievance processes from the outset can reduce the risk of interruption after EPC work begins.
Resource
Verify the measurement basis, long-term adjustments and uncertainty range.
Constructability
Reflect the effects of ground conditions, access, logistics and climate in the design and construction programme.
Land rights
Review legal rights alongside actual users and community impacts.
03 · Grid connection
Distinguish connection approval from the ability to sell generation
The existence of a grid connection point does not mean all generated electricity can be sold. Transmission capacity, congestion, curtailment rules, the scope of reinforcement and its completion date determine actual sale volumes and revenue.
The PPA and connection agreement should consistently address who performs the grid-impact assessment, pays reinforcement costs, bears delay risk and compensates for curtailment. Test a separate scenario in which plant and transmission-line completion dates do not align.
04 · PPA & offtaker
Check the offtaker's ability to pay and perform, not just the PPA tariff
A long-term PPA supports revenue, but contracted sales may not become cash if the counterparty's financial health, tariff-collection structure or enforceability of government support is weak. This is why protection against late payment, currency-conversion and transfer restrictions, and political events matters.
Energy measurement, curtailment, deemed energy, force majeure, change in law and termination compensation should work together. Rather than assigning every risk to either the public or private side, allocate controllable risks to the party able to manage them and use transparent adjustment mechanisms for uncontrollable events. This can produce more competitive pricing over the long term.
Credit
Assess the offtaker's ability to pay and credit support such as guarantees or escrow.
Currency
Check mismatches between import currency, debt currency and the currency of power payments.
Termination
Confirm that termination compensation by cause and lender rights fit the financing structure.
05 · Bid & EPC
Test a low price against deliverable technical and contractual terms
Bidder qualification cannot be assessed from previously installed capacity alone. Review experience in similar climate and grid conditions, the supply chain for critical equipment, financing experience, and the ability to manage local permits and subcontractors. An unusually low bid also requires a clarification process to check for omitted scope or unrealistic financing assumptions.
The EPC contract should clarify not only completion dates and damages but also reference generation, availability, performance-test conditions and long-term degradation assumptions. If warranties for critical equipment such as modules, inverters and turbines are shorter than the project company's obligations or cannot be transferred, contractual protection will not cover the actual operating period.
06 · Completion & operations
Build a performance-data system that continues after completion testing
A performance test shows the plant's condition on a particular date, while long-term revenue depends on years of availability, degradation, cleaning, maintenance and curtailment. Before completion, confirm ownership of SCADA data, measurement accuracy, cybersecurity, defect-assessment rules and O&M reporting formats.
Warranty claims, insurance and lender reporting depend on distinguishing generation losses caused by resource shortfalls, equipment problems, grid restrictions or operating decisions. Defining the cause-classification system during design helps the operating team identify losses it can improve, rather than only report results.
Renewable-energy pre-bid checklist
Before finalizing the pricing model, record the evidence available for rights, connections, revenue and performance.
| Review item | Documents to check | Pass criterion | Condition for holding |
|---|---|---|---|
| Land and site | Title, lease, boundaries and access | Duration and use rights match the project life | Disputes, resettlement or access rights are unconfirmed |
| Resource and yield | Raw data and loss and degradation assumptions | A model that can be independently reviewed | Insufficient measurement period or evidence for losses |
| Grid | Connection point, reinforcement and curtailment | Clear responsibility, cost and schedule | Reinforcement responsibility or curtailment terms are unclear |
| PPA and currency | Tariff, payment security and currency conversion | Revenue protection is consistent with cost currencies | Currency or transfer risk is unallocated |
| EPC and localization | Supply chain, local-content ratio and tax | Defined route to compliance and supporting evidence | Penalties exist without measurement criteria |
| Permits and E&S | Permit list, ESIA and consultation | Confirmed process, responsibility and deadline | A critical permit comes too late in the schedule |
Treat a hold item as an explicit condition that may change pricing, timing or the decision to bid, rather than merely deducting points.
Practical takeaways
- Procurement design allocates site, grid and demand risks as well as discovering prices.
- Assess the lowest bid against the completeness of its assumptions, financing certainty and a realistic schedule.
- Completion performance tests must connect to long-term operating data to preserve the value of generation.
