In March 2025, with the "14th Five-Year Plan" coming to an end, China is accelerating towards a new era of green transformation with "carbon emission dual control" as the core. The "Work Plan for Accelerating the Construction of a dual carbon emission Control System" issued by The State Council makes it clear that the "15th Five-Year Plan" period will implement a dual carbon emission control degree with intensity control as the main and total volume control as the supplement, and the reduction of carbon emission intensity has officially become a binding indicator for national economic and social development. This policy shift marks China's comprehensive transition from "dual control of energy consumption" to "dual control of carbon emissions", the development of non-fossil energy is no longer limited, the new energy industry has ushered in historic opportunities, and the high-carbon industry is facing stricter accounting and supervision.
Carbon emission crisis: The impact of traditional insulating oils on pollution
The world consumes more than 2 million tons of mineral insulation oil every year, and the carbon emission intensity of the production process reaches 3.2 tons of CO₂/ ton of oil; The biodegradation rate of mineral oil is less than 30%, and the soil and water source are polluted after waste, and the restoration cost is as high as 1200 yuan/ton. (Source: IEA Global Power Report 2023) Companies face pressure to disclose carbon data in ESG reports; Environmental compliance costs are rising year by year.
Technology Breaker: The carbon-neutral logic of biodegradable insulating oils
Deep natural ester insulating oil uses bio-based raw materials (rapeseed oil, soybean oil), carbon footprint is 70% lower than mineral oil (SGS certification); The carbon emission intensity of the production process is only 0.9 tons of CO₂/ ton of oil (calculated by the Chinese Academy of Environmental Sciences). In the use stage, the oxidation resistance of Debose natural ester insulating oil is increased by 3 times, the transformer maintenance cycle is extended by more than 2 times, and the maintenance frequency is reduced. At the retirement stage, the biodegradation rate is > 98% (in line with the EU REACH standard), and there is no need for hazardous waste treatment to achieve carbon reduction throughout the life cycle.

Landing verification: From the laboratory to the 100 billion market
A central enterprise project: 200 10kV distribution transformers were converted to Deposhi natural ester insulating oil, reducing annual carbon emissions by 12,000 tons, equivalent to planting 65,000 trees; Operation and maintenance costs decreased by 28% (source: State Grid Energy Efficiency Report 2023).
A Shenzhen Research Institute project: After replacing mineral oil, the carbon footprint of a single transformer decreased by 53.7% (measured by a third-party carbon verification institution); Won the local "low-carbon demonstration project" subsidy of 1.2 million yuan.
Policy dividend: Seize the opportunity of green transformation
Mandatory standards: The State Grid requires that the utilization rate of newly purchased transformer environmental protection oil in 2025 be ≥30%; The EU CBAM carbon tariff will include transformers in the scope of control (implemented in 2026).
Economic incentives: Selected in the Ministry of Industry and Information Technology "National Industrial energy-saving technology equipment recommended catalogue", the purchaser enjoys 15% VAT deduction; Local governments give incentives of 50 yuan per ton of CO₂ emission reduction for projects that reduce their carbon footprint by more than 40%.
User value: win-win for environmental protection and benefit
Compliance and hedging: to meet domestic and foreign carbon tariffs, ESG disclosure and other mandatory requirements;
Reduce costs and increase revenue: reduce operation and maintenance costs by 20%-30%, while obtaining carbon trading income;
Brand value added: "Build a green supply chain" label to enhance bidding competitiveness.
Shuangjiang Energy is writing a green answer sheet made in China with technological innovation. This is not only a revolution in the transformer industry, but also China's initiative in the global energy transition. In the future, with the full roll-out of carbon footprint certification and the accelerated construction of smart grid, Shuangjiang Energy will continue to deepen green technology and contribute "China's power" to the goal of carbon neutrality.
