Packaging Printing Factory's 3 New Changes in Environmental Electricity Tariffs for 2026 - 3 Types of Electricity Bills That Printing Factory Owners Must Calculate

Wuxi Lexiang has, from 2023 to the present, provided electricity cost optimization consulting for a total of 26 printing factories. Among these, 18 printing factories have seen their electricity cost proportion rise from 5-8% to 10-15% starting from 2025. Many printing factory owners believe that "electricity cost = consumption × unit price", but starting from 2026, three new changes in the environmental electricity pricing (peak-valley pricing / carbon cost / direct green power purchase) have completely transformed the way printing factories calculate their electricity bills. Below, we will discuss the three new changes + three types of electricity bills + four types of electricity pricing adaptation strategies for printing factories.

Why Printing Factory Owners Need to Understand the 2026 Environmental Electricity Pricing

Many people think that the electricity cost for printing factories = consumption × unit price, but starting from 2026, three new changes in environmental electricity pricing are forcing printing factory owners to recalculate their expenses:

1. Peak-valley pricing fully implemented—Starting from 2024, the National Development and Reform Commission requires all industrial and commercial users nationwide to implement peak-valley pricing, and starting from 2026, the price difference between peak and valley periods will be further widened (peak period electricity price +20-30%, valley period electricity price -30-40%). By shifting production from daytime to nighttime, printing factories can save 15-25% on electricity costs
2. Carbon cost internalization—Starting from 2026, the national carbon trading market will expand, and printing factories with annual carbon emissions ≥5000 tons CO2e will be included in the carbon trading market, with a carbon price of 50-100 CNY/ton CO2e, resulting in an annual carbon cost of 250,000-1,000,000 CNY for printing factories
3. Direct green power purchase—Starting from 2024, industrial and commercial users are allowed to directly purchase green power (wind power / photovoltaic / hydropower), with green power prices 0.05-0.15 CNY/kWh higher than thermal power, but green power can offset carbon emissions + partially exempt from carbon trading

Real Case: In November 2025, a printing factory in Jiangsu (with an annual electricity consumption of 1.2 million kWh) received a 2026 electricity price adjustment notice, with the peak-valley price difference widened from 0.4 CNY/kWh to 0.6 CNY/kWh, and the carbon trading market entry threshold lowered to 5000 tons CO2e. The factory owner recalculated and found that, with the existing production model, the electricity bill + carbon cost would increase by 300,000 CNY in 2026. By combining peak-valley pricing arbitrage + direct green power purchase + energy-saving renovation, the factory can save 180,000-220,000 CNY.

Three Types of Electricity Bills

Printing factory owners must clearly calculate three types of electricity bills:

First Type of Bill: Peak-Valley Price Difference Account
- Algorithm: (Peak period electricity consumption × Peak price + Flat period electricity consumption × Flat price + Valley period electricity consumption × Valley price)
- Example: A printing factory with an annual electricity consumption of 1 million kWh, with a peak price of 1.2 CNY/kWh, a flat price of 0.8 CNY/kWh, and a valley price of 0.4 CNY/kWh, under the original production model (80% peak + 20% flat), the annual electricity bill is 1 million × 80% × 1.2 + 1 million × 20% × 0.8 = 1.12 million CNY; under the peak-valley arbitrage model (30% peak + 30% flat + 40% valley), the annual electricity bill is 1 million × 30% × 1.2 + 1 million × 30% × 0.8 + 1 million × 40% × 0.4 = 760,000 CNY, saving 360,000 CNY/year

Second Type of Bill: Carbon Cost Account
- Algorithm: Annual carbon emissions × Carbon price = Annual carbon cost
- Example: A printing factory with an annual electricity consumption of 1 million kWh, with an annual Scope 2 emission of 1 million × 0.5819 = 581.9 tons CO2e, and an annual Scope 1 + Scope 3 emission of about 1000 tons CO2e, total emissions are about 1580 tons CO2e (not reaching the 5000-ton threshold, not yet included in carbon trading); a large printing factory with an annual electricity consumption of 8 million kWh, with total emissions of about 126,000 tons CO2e (far exceeding the 5000-ton threshold), calculated at 80 CNY/ton CO2e, the annual carbon cost is 1 million CNY

Third Type of Bill: Green Power Profit Account
- Algorithm: (Green power price - Thermal power price) × Annual green power consumption - Cost of green power offsetting carbon emissions
- Example: A printing factory with an annual electricity consumption of 1 million kWh, with 30% using green power (300,000 kWh), green power price 0.1 CNY/kWh higher than thermal power, additional green power cost 300,000 × 0.1 = 30,000 CNY; green power offsets 300,000 × 0.5819 = 174.6 tons CO2e emissions, carbon price 80 CNY/ton CO2e, carbon trading exemption benefit 174.6 × 80 = 14,000 CNY, net green power cost 16,000 CNY/year. But green power also has hidden benefits: ESG report highlights + improved customer acceptance, potential annual orders increase by 500,000-2,000,000 CNY

Real Comparison of Three Bills

Assuming a printing factory with an annual electricity consumption of 1 million kWh + annual output value of 80 million CNY + clients including brands like L'Oréal.
Here is the real comparison of the three bills:

1. Original Production Model—Annual electricity bill 1.12 million CNY + carbon trading not yet participated, total electricity bill + carbon cost 1.12 million CNY/year
2. Peak-Valley Arbitrage Model—Annual electricity bill 760,000 CNY + carbon trading not yet participated, total electricity bill + carbon cost 760,000 CNY/year, saving 360,000 CNY/year
3. Peak-Valley Arbitrage + Green Power Direct Purchase Model—Annual electricity bill 780,000 CNY (peak-valley arbitrage + 30% green power) + carbon trading exemption benefit 14,000 CNY, total electricity bill + carbon cost 766,000 CNY/year, saving 354,000 CNY/year + ESG report highlights
4. Peak-Valley Arbitrage + Green Power Direct Purchase + Energy-Saving Renovation Model—Annual electricity bill 600,000 CNY (peak-valley arbitrage + 30% green power + energy-saving renovation -15% electricity consumption) + carbon trading exemption benefit 14,000 CNY, total electricity bill + carbon cost 586,000 CNY/year, saving 534,000 CNY/year

Real Data: Among the four models, the peak-valley arbitrage + green power direct purchase + energy-saving renovation model has the lowest total cost. Printing factory owners should choose based on "annual electricity consumption scale + customer structure + investment budget".

Four Types of Printing Factory Electricity Pricing Adaptation Strategies

Printing factory owners choose according to "annual electricity consumption scale + customer structure + investment budget" four types of strategies:

Strategy 1: Annual electricity consumption ≤ 1 million kWh + relaxed customer structure
- Choice: Peak-Valley Arbitrage (production hours shifted from daytime to nighttime)
- Investment: 0-50,000 CNY (including equipment timing + production scheduling adjustment)
- Saving: Annual saving 100,000-200,000 CNY

Strategy 2: Annual electricity consumption 1-5 million kWh + customer structure includes brand owners
- Choice: Peak-Valley Arbitrage + Green Power Direct Purchase (30%)
- Investment: 50,000-200,000 CNY (including green power direct purchase agreement + production scheduling adjustment)
- Saving: Annual saving 200,000-500,000 CNY + ESG report highlights + improved customer acceptance

Strategy 3: Annual electricity consumption 5-10 million kWh + customer structure includes multinational brands
- Choice: Peak-Valley Arbitrage + Green Power Direct Purchase (50%) + Energy-Saving Renovation
- Investment: 500,000-2,000,000 CNY (including photovoltaic + energy-saving equipment + green power direct purchase agreement)
- Saving: Annual saving 800,000-1,500,000 CNY + ESG report core highlights

Strategy 4: Annual electricity consumption ≥ 10 million kWh + customer structure includes EU customers
- Choice: Peak-Valley Arbitrage + Green Power Direct Purchase (80%) + Energy-Saving Renovation + Carbon Trading Management
- Investment: 2,000,000-5,000,000 CNY (including large-scale photovoltaic + energy storage + carbon trading management team)
- Saving: Annual saving 2,000,000-4,000,000 CNY + CBAM exemption + EU order priority

Detailed Interpretation of Three New Electricity Bill Changes

Printing factory owners must understand the detailed details of the three new electricity bill changes:

1. Peak-Valley Pricing—Starting from 2024, all industrial and commercial users nationwide will implement peak-valley pricing, with peak hours 8:00-21:00, and valley hours 21:00-8:00 the next day. Starting from 2026, the peak-valley price difference will be further widened, with some provinces having a peak-valley price difference of 0.6-0.8 CNY/kWh. By shifting production hours from daytime to nighttime, printing factories can save 15-25% on electricity costs
2. Carbon Cost—Starting from 2026, the national carbon trading market will expand, and printing factories with annual carbon emissions ≥5000 tons CO2e will be included in the carbon trading market. Carbon price 50-100 CNY/ton CO2e (2026 forecast). Printing factory's annual carbon cost 250,000-1,000,000 CNY. It is recommended that printing factory owners respond in 3 steps: 1) Establish a carbon emission data collection system; 2) Set carbon reduction targets; 3) Participate in carbon trading or purchase carbon quotas
3. Green Power Direct Purchase—Starting from 2024, industrial and commercial users are allowed to directly purchase green power. Green power price 0.05-0.15 CNY/kWh higher than thermal power, but green power can offset carbon emissions + partially exempt from carbon trading. It is recommended that printing factory owners respond in 3 steps: 1) Sign a direct purchase agreement with local green power suppliers; 2) Choose a green power combination of wind power / photovoltaic / hydropower; 3) Disclose green power usage in ESG reports

Three Types of Electricity Bill Failure Cases

Printing factory owners are prone to three types of pitfalls in the three new changes in electricity bills:

1. Peak-Valley Pricing Failure—In December 2024, a printing factory owner in Zhejiang moved all production hours to nighttime, but the night shift labor cost +30%, actual electricity cost savings - increased labor cost = net loss. Lesson: Peak-valley arbitrage must balance electricity savings + labor cost + equipment life
2. Carbon Cost Failure—In September 2025, a printing factory in Jiangsu was included in the carbon trading market, with a carbon quota purchase cost of 500,000 CNY, and the factory owner had not planned ahead. Lesson: Printing factories should plan carbon reduction in 2025 to avoid passive purchase of carbon quotas in 2026
3. Green Power Direct Purchase Failure—In June 2025, a printing factory in Guangdong signed a green power direct purchase agreement, but the green power supplier could not supply stably, and could only use thermal power for some periods, with the actual green power proportion only 15%. Lesson: Before signing a green power direct purchase agreement, printing factories must assess the stability + flexibility of the supplier

Conclusion: The Three New Changes in Environmental Electricity Pricing Are a "Must-Study" for Printing Factory Owners

Many printing factory owners think that "electricity cost = consumption × unit price", but starting from 2026, the three new changes in environmental electricity pricing force printing factory owners to recalculate their expenses. Three bills (peak-valley price difference / carbon cost / green power profit) + four adaptation strategies (peak-valley arbitrage / green power direct purchase / energy-saving renovation / carbon trading management), printing factory owners must be aware of. The wrong choice will increase the electricity bill + carbon cost by 300,000-500,000 CNY in 2026, while the right choice will save 500,000-2,000,000 CNY + capture EU orders.
