What are the cost reduction techniques for annual procurement of photovoltaic energy storage components?
The core is to centralize dispersed demand, lock in prices with long-term contracts, conduct price increase verification, promote domestic substitution, and supplement with digital inventory and logistics, turning “passively accepting price increases” into “actively locking in costs.”
I.
General Outline and Category Classification of Annual Procurement Strategies
- First, conduct an annual expenditure analysis (Spend Analysis): Analyze the procurement distribution of each category and project, identify opportunities for independent procurement and consolidation, which is the foundation of all cost reduction (Source: Protocol).
- Categorized Management: Focus on A-category (high-value core materials such as battery cells and PCS), while standardize and merge B/C categories to avoid a one-size-fits-all approach.
- Demand Management: Collaborate with R&D/projects to streamline specifications and eliminate “nice-to-have” practices, cutting ineffective procurement at the source.
- Establish a unified demand sharing platform for cross-departmental information exchange, avoiding duplicate orders and economies of scale caused by information silos.
- Build a Closed-Loop Procurement Metrics: Monthly review of procurement amounts, price reductions, and profits/losses, solidifying cost-reduction experiences into standard capabilities.

Centralized Procurement and Supplier Integration
-
Centralized procurement integrates company-wide/multi-project demands, trading volume for price: Merging similar materials, bulk procurement can generally save 10-30% (Source: Douyin Procurement Strategy).
Streamlining Suppliers: Reduce the number of suppliers for similar raw materials from 20-30 to 3-5, consolidating procurement volume to obtain better prices, stable supply, and quality assurance.
Optimizing Supplier Structure: Establish long-term framework agreements with automatic renewal conditions to reduce the time cost of repeated bidding.
Diversification and the “Catfish Effect”: Always maintain 3 alternative suppliers and introduce new suppliers to force price reductions; retain at least one qualified backup supplier for critical materials to control risk.
Strategic Procurement Instead of Order-by-Order Price Comparison: Select suppliers based on total value rather than unit price, and regularly test the market using RFP/RFQ/reverse auctions.
III. Long-Term Contracts, Price Lock-in, and Price Linkage Mechanisms
- Long-Term Contracts for Lower Prices: Haibo Sicheng signed a ten-year strategic cooperation agreement with CATL, with a procurement volume of no less than 200GWh from 2026 to 2028. Haichen Energy Storage and CRRC Zhuzhou signed an agreement for a cumulative procurement volume of no less than 120GWh during the 15th Five-Year Plan period, locking in stable supply and better prices (Source: China Economic Net).
- Annual Framework Agreements Set Fixed or Floating Price Formulas and Upper and Lower Limits: These agreements stipulate price adjustment mechanisms and automatic renewal conditions to mitigate market volatility risks.
- Price Index Linkage: Price indexation clauses are set (linked to metal indices such as lithium carbonate, copper, and aluminum) and annual upper and lower limits for price increases and decreases are agreed upon.
Starting from November 2025, the pricing of energy storage cells for some projects will be linked to the average price of lithium carbonate in the previous month (Source: Securities Times/QuickBooks). - Lithium prices are likely to rise rather than fall in 2026. Lithium carbonate at around 150,000 yuan/ton is the bottom of the cycle. Cost control has become the core capability for the survival and development of lithium battery companies (Source: Securities Times).
The industry chain is entering a phase of competition focused on securing large volumes: long-term contracts are becoming larger and longer-term, leading companies are deeply integrated with upstream suppliers, and market concentration continues to increase.
Cost reduction is shifting from “single-unit price reductions” to a systemic approach: a combination of centralized procurement, long-term contracts, domestic substitution, digitalized inventory and logistics, and price linkage is being implemented.
Large-capacity battery cells, domestically produced components, and AI-powered procurement analysis will become new tools for annual cost reduction.
For purchasers, the key to annual cost reduction for photovoltaic energy storage components is to focus on expenditure analysis, secure long-term contract prices, verify price increases, promote domestic substitution, and continuously consolidate achievements using digitalization and TCO (Total Cost of Ownership) metrics.
Hybrid pricing to balance risk: Fixed price + index trigger (e.g., 60-80% price lock-in, 20-40% index-linked) can reduce price volatility exposure by about 1/3 (Source: McKinsey).
Bill and Hold: Buy inventory at today’s price, have suppliers manage and ship in batches, locking in low COGS without warehousing pressure.
IV.
Negotiation Skills and Business Combinations
Price increases should be verified first: Check open market prices (futures/spot indices), competitor purchase prices, and require suppliers to break down costs to distinguish between genuine/false/structural price increases before responding.
Tiered pricing linked to volume: For every 30% increase in purchase volume, the unit price decreases by about 5%; increasing annual purchase volume from 500 tons to 800 tons can reduce the price by 3 percentage points.
**Splitting Negotiation Method:** Raw material costs are increased according to market conditions, while processing fees, logistics fees, and management fees are reduced item by item, limiting the total price increase to within the material cost ratio.
**Using Non-Price Bargaining Chips:** Exchange payment terms for discounts (cash payment for 3-5%), shorten payment cycles from 60 days to 30 days for lower rates, and use bank drafts to reduce financial costs.
**Communication Techniques and Rhythm:** Empathize first, then back off; use silence to offer concessions; negotiate between senior management; negotiate through different channels (Q2-Q3 lithium price window, negotiate with suppliers before the end of the quarter) to obtain better terms (Source: QuickBooks/Senior Procurement).
**V. Technology Cost Reduction and Domestic Substitution**
**Material Substitution Techniques:** Domestic substitution for imports; achieving performance standards can reduce costs by 30-50%; collaborate with R&D to replace high-priced imported materials with low-cost alloys/materials (Source: 18 Strategies from Procurement Gurus).
VAVE Value Engineering: Collaborating with suppliers to disassemble products, reduce parts thickness, simplify packaging, and consolidate processes, saving costs shared by both parties; optimizing three core raw materials can save up to 15% per month.
Standardization Cost Reduction: Reducing customized parts and increasing the purchase volume of general-purpose parts, reducing 46 packaging specifications to 12, directly lowering inventory costs.
Large-capacity battery cells (314Ah mainstream, 500Ah+ accelerated) have low unit manufacturing costs and long cycle life, making them the directional choice for procurement in 2026 (Source: Securities Times).
Technological Collaboration: Requiring suppliers to upgrade their technology and participate in capacity planning, jointly developing new materials/processes to lock in costs from the source.
VI. Inventory, Logistics, and Digitalization
VMI Supplier Managed Inventory: Allowing suppliers to replenish as needed and settle accounts based on usage, reducing inventory and capital occupation.
Logistics Combination Strategy: Combined transportation and full truckload delivery reduce freight costs by approximately 40%, and sea/land transportation is selected to replace air freight based on delivery time to reduce costs.
Demand Forecasting and MRP: Use data forecasting to avoid stockpiling and material shortages, increase inventory turnover from 15 times to 20 times, and strictly control stagnant inventory.
Build a Price Intelligence Database: Record past purchase prices/cost structures/market conditions, so that you can easily check the inflated prices of suppliers next time (Source: Senior Procurement).
Electronic Ordering and Process Standardization: Shorten the inquiry, approval, and ordering cycle, reduce internal friction, and reduce costs through process optimization.
VII. Procurement Recommendations
Establish an Annual Procurement Calendar: Q1 for expenditure analysis and framework agreements, Q2-Q3 for locking in lithium/metal prices, Q4 for review and planning for the following year, using timing to gain bargaining power.
Use Total Cost of Ownership (TCO) instead of unit price for decision-making: Incorporate delivery time, quality, failure rate, warranty, and maintenance into the cost of each unit to avoid low price and low quality.
Maintain at least three alternative suppliers and compare prices regularly. Obtain dual-source certification for key materials to prevent reliance on single-point suppliers leading to price gouging.
Write cost reductions into contracts instead of verbally: Agree on price index linkage, upper and lower limits, automatic renewal conditions, performance KPIs, and breach of contract compensation to close loopholes for overcharging (reconciliation can uncover 3-7% over-collection).
Data-driven and continuous improvement: Monthly review of price reduction magnitude and year-on-year trends. Use procurement ROI to measure and solidify standard actions, making cost reduction a systemic process rather than a one-off price cut.
