How should delivery schedules be determined for annual framework agreements regarding PV and energy storage components? It boils down to three core elements: a two-stage process—competitive selection to establish the framework (unit price, quality, terms, validity period) followed by placing orders based on actual demand;
pricing options such as fixed, adjustable, or price-capped models; and delivery terms defined as “delivery within X days of order receipt” plus clauses for breach of contract and schedule adjustments.
Strategies involve locking in volumes rather than prices, while balancing forecast constraints with operational flexibility.
I.
Definition and Principles of Annual Framework Agreement Delivery Schedules
- Framework Agreement: A centralized procurement method that aggregates similar anticipated demands, establishes a supply-demand agreement in a single step, and implements it in stages. Stage 1 involves aggregating anticipated content and quantities and selecting shortlisted suppliers through competition; Stage 2 involves signing specific implementation contracts based on actual demand (Source: *Guidelines for the Organization and Implementation of Framework Agreement Procurement*).
- Applicable Scenarios: Emergency or sporadic procurement where quantities and timing are difficult to pinpoint precisely, or frequent repetitive procurement of similar items;
long agreement terms, uncertain quantities/timelines, and significant risk exposure for suppliers (Source: *Guidelines for the Organization and Implementation of Framework Agreement Procurement*). - Agreement Content: Description of the subject matter (scope, delivery/completion schedule, quality, acceptance, after-sales service), unit price or estimated total price, validity period, pricing type and procurement procedures, rights and obligations, dispute resolution, and procurement contract templates (Source: *Guidelines for the Organization and Implementation of Framework Agreement Procurement*).
- Shortlisted Suppliers: Generally no fewer than two (unless only one meets the criteria);
estimated procurement quantities serve only as a reference for quoting and do not constitute a commitment to actual transaction volumes (Source: *Guidelines for the Organization and Implementation of Framework Agreement Procurement*).

How to Structure It: Two Stages and Key Terms
- Stage 1 (Framework Establishment): Determine unit prices, quality standards, transaction terms (delivery/acceptance/after-sales service), and the agreement’s validity period. Stage 2 (Execution): Sign and fulfill contracts based on actual procurement quantities (Source: *Guidelines for the Organization and Implementation of Framework Agreement Procurement*).
- Selection of Competitive Methods: Public Tendering (suitable for one-time pricing, clear requirements, and robust market competition);
Inquiry and Comparison (suitable for both one-time and two-stage pricing); Negotiation (suitable for two-stage pricing, hard-to-define requirements, and limited competition) (Source: *Guidelines for the Organization and Implementation of Framework Agreement Procurement*). - Validity Period: Typically one year; extensions allowed (e.g., ≤6 months for Huiyuantong components; ≤3 months for Datang energy storage);
BPAs (Blanket Purchase Agreements) often run for 12 months with options to renew for 1–2 years, though terms exceeding 3 years are generally not recommended (Source: Guangdong Huiyuantong / East Money / Business in a Box). - Order Allocation: Guangdong Huiyuantong employs a “lowest-price priority” model, ranking winning bidders from lowest to highest unit price;
poor performance is treated as a waiver of rights, leading to share reallocation (Source: SPIC E-commerce Platform). - Transaction Price: One-time pricing = the framework unit price becomes the implementation contract price (barring agreed-upon adjustment scenarios);
Two-stage pricing = the framework unit price serves as the price ceiling, with the final transaction price determined through a secondary competition (Source: *Guidelines for the Organization and Implementation of Framework Agreement Procurement*).
III.
Pricing Mechanisms (Fixed / Adjustable / Price Ceiling + Linked Pricing)
- Fixed Price: Prices cannot be changed during the validity period except under agreed-upon exceptions; suitable for stable markets, accurate or limited quantity fluctuations, low volumes, or durations shorter than six months (Source: *Guidelines for the Organization and Implementation of Framework Agreement Procurement*).
- Adjustable pricing: Involves setting trigger conditions and ranges, base prices and indices, and adjustment factors, standards, or methods.
Suitable for scenarios with high price volatility, significant discrepancies between estimated and actual quantities, or contract durations exceeding six months (Source: *Guidelines for the Organization and Implementation of Framework Agreement Procurement*). - Price ceiling: Involves setting a maximum unit price or tiered pricing. Applicable only to secondary pricing (cannot be used for initial shortlist selection via tendering).
Suitable for scenarios with significant market price variance, expected sharp price drops, or difficulty in estimating quantities and specifications (Source: *Guidelines for the Organization and Implementation of Framework Agreement Procurement*). - Price linkage example: Guangdong Huiyuantong’s PV module settlement is dynamically adjusted based on the average price of distributed TOPCon modules in China (as reported by PV Infolink).
The benchmark price set on May 6, 2026, was 0.78 RMB/W, with price adjustments triggered if absolute price fluctuations exceeded 3% (Source: SPIC E-commerce Platform). - Fixed volume, floating price: LONGi’s glass procurement (2022–2026) covers 250 million square meters (approx. 5.531 billion RMB) with monthly price negotiations and batch procurement—combining long-term supply security with market-based pricing (Source: Shanghai Stock Exchange).

Examples of Delivery Schedule and Terms
- PV modules: Delivery required within 7–15 days of the winning bidder receiving the order and prepayment; two spare units per MW are included in the total price (Source: Guangdong Huiyuantong).
- Datang string inverters (9.5 GW): First batch ready for delivery within 30 days of receiving the purchase order;
full delivery within 3 months of order effectiveness; contract valid for one year (Source: International Solar PV Network). - Tower Energy PV materials: Delivery to the designated location within 30 days of order issuance;
warranty periods are 12 years for modules, 5 years for grid-connection cabinets and inverters, and 2 years for other components; one-year contract with on-demand ordering and settlement (Source: National Public Resource Trading Platform). - CECEP Energy Storage EPC: Delivery to be completed within 70 days of contract signing;
Datang Energy Storage System 5GWh framework valid for one year or until 110% of the estimated volume is reached (Source: National Public Resource Trading Platform/East Money). - Default clauses: Guangdong Huiyuantong sub-project incurs a daily penalty of 0.5% for delays;
contract termination and a claim for 20% of the contract value are permitted if the cumulative penalty reaches 10% or the delay exceeds 15 days; exceeding the allowed number of delivery postponements (twice) is deemed a forfeiture of rights (Source: SPIC E-commerce Platform).
V. Quantity/Forecast/Flexibility Clauses
- Clear forecast constraints: Enphase uses a rolling 12-month forecast;
the first 90 days are bucketed weekly and constitute a binding purchase order, while the remainder is non-binding—suppliers prepare materials based on this (Source: Enphase). - Long-lead-time material procurement: Materials with lead times >8 weeks are purchased in advance based on forecasts, with lists generated quarterly;
suppliers purchase according to the Approved Vendor List (AVL) and must provide evidence of annual cost reductions or participate in annual competitive bidding (Source: Enphase). - Sun Model: Rolling 6-quarter non-binding forecast with weekly updates; blanket POs are non-binding and do not serve as a basis for material preparation;
rescheduling is free within 90 days, incurs a 1%/month fee for 91–180 days, and cancellation limits apply to scrapped materials (Source: SEC). - BPA flexibility: Sets a Not-to-Exceed (NTE) limit (historical annual spend + 15–20% buffer) with written notification required upon 80% consumption; limits authorized signatories to 2–3 individuals;
every release order must reference the framework agreement number (Source: Business in a Box). - Global framework: United Utilities BESS framework covers an initial 4 years with options to extend by 2+2 years; involves 2–3 suppliers and a value of approx. £40 million; awarded via direct award or mini-competition; evaluation based on 50% commercial and 50% technical criteria (Source: Find a Tender).
VI. Factors Affecting Annual Framework Delivery Schedules
- Baseline Lead Times: BESS procurement takes 8–12 weeks, with an additional 8–16 weeks for production and delivery (varying by standard vs. custom specs); module delivery takes 7–15 days based on a “spot stock + short production cycle” model (Source: ASP / Guangdong Huiyuantong).
- Quantity and Batch Size: Larger orders require more time for production and QC;
module lead times extend during peak seasons/high-demand periods (Q3–Q4), necessitating early ordering; shipping costs are more economical during off-peak seasons (Source: Portlandia). - Certification Windows: UN38.3, IEC, UL, and CE certifications take 4–8 weeks or even 2–6 months;
these processes should run parallel to the production schedule within the framework period to avoid impacting the critical path (Source: ASP). - Trade and Policy: Tariffs or anti-dumping measures can drive up landed costs by 15–30% within months;
direct import procurement should utilize flexible contracts with short commitment windows (Source: Portlandia). - Supplier Ramp-up and Capacity: New production lines experience high rework rates and low yields during ramp-up, whereas mature plants offer stability;
framework delivery schedules should be based on actual ramp-up capabilities rather than nominal capacity (Source: J.v.G / Portlandia).
VII. Procurement Recommendations
- Lock in Volume, Not Price;
Negotiate Monthly: Adopt a model similar to LONGi’s long-term glass supply agreements—securing supply while adjusting prices to market rates—to avoid losses from holding high-cost inventory during sharp price drops (Source: Shanghai Stock Exchange). - Opt for Adjustable or Linked Pricing: Use adjustable pricing for high volatility or contract terms exceeding six months;
link pricing to PV Infolink average market rates with a +3% trigger threshold, ensuring the index is public and auditable (Source: SPIC E-commerce Platform). - Clearly Define Delivery Start Points and Default Terms: Specify “delivery within X days of order/down payment receipt” rather than providing a vague delivery date;
explicitly stipulate a daily penalty of 0.5% for delays, a cumulative penalty cap, and specific ratios for contract termination and claims (Source: Guangdong Huiyuantong). - Forecast constraints and flexible scheduling: Firm commitments for the first 90 days (requiring suppliers to stock materials based on Purchase Orders), with flexibility to reschedule orders beyond the 90-day window; long-lead-time materials procured in advance under framework agreements based on quarterly lists (Source: Enphase/SEC).
- Retained payments: 30% deposit + 60% upon shipment/dispatch + 10% after Site Acceptance Testing (SAT), with a final 5–10% withheld for 60–90 days;
full payment is contingent upon final acceptance (Source: ASP).
Trends and Summary
- Standardization of framework agreements: Annual frameworks are common for modules, inverters, and energy storage systems, typically valid for one year with options to extend by 3–6 months;
a two-stage process—combined with either “lowest price” or “balanced allocation” awarding strategies—has become the norm (Source: SPIC E-commerce Platform/East Money). - Widespread use of price-linkage mechanisms: Index-based price adjustments for TOPCon products alongside monthly negotiations for large orders; “fixed volume/floating price” models combined with index linkage balance supply security against market volatility (Source: SPIC E-commerce Platform/Shanghai Stock Exchange).
- Global multi-supplier frameworks: Initial 4-year terms with 2+2 year extension options;
engagement of 2–3 suppliers simultaneously via direct award or mini-competitions to mitigate single-supplier risk (Source: Find a Tender). - Routine supplier management: Annual pre-qualification renewals, certified supplier databases, third-party inspections, and performance scorecards (tracking on-time delivery, defect rates, warranty response, and efficiency) to inform renewal decisions (Source: ASP).
- For buyers, the answer to how delivery schedules are set in annual framework agreements for PV and energy storage components is: a two-stage process where Stage 1 establishes unit prices and terms, and Stage 2 involves placing orders on demand;
pricing models (fixed, adjustable, or index-linked) are selected based on market conditions; delivery terms specify “arrival X days after order receipt,” liability caps for default, and rescheduling rules;
and operational strategies include firm commitments for the first 90 days with flexibility thereafter, advance stocking of long-lead-time materials, and retained payments—transforming annual procurement into a low-risk, routine process, which is the fundamental purpose of framework agreements.
