Project Overview

Against the backdrop of China's “dual carbon” strategic goals and the accelerated development of the new electricity system, parks dominated by public and residential buildings—exhibit prominent energy consumption and carbon emission levels, possess abundant and diverse flexible resources, and benefit from a solid foundation for electrification. They therefore serve as critical scenarios for advancing green and low-carbon transition while supporting stable grid operation.

As spaces for intensive office and research activities, parks have concentrated building energy consumption and carbon emissions. Conventional park energy systems are dominated by passive energy consumption, with insufficient renewable energy utilization and limited supply-demand interaction capability, making them incompatible with the high-standard positioning of Xiong'an New Area as a “green and smart new city”. The primary reason lies in the lack of an integrated development approach that coordinates clean energy utilization, flexible load regulation, and carbon management throughout park construction, and the absence of a complete and feasible implementation pathway.

Rooted in the green-low-carbon development positioning of Xiong'an New Area, this project delivers Xiong'an's first implemented all-electric smart zero-carbon park.Guided by the design philosophy of “internal carbon reduction, interactive carbon reduction, market-oriented carbon reduction and unified integration”, the project constructs a hybrid energy supply technology-based clean heating and cooling energy station, a full-domain DC system, a photovoltaic-storage-DC-flexibility power distribution system, and an integrated platform for smart park operation and control. It develops a replicable and scalable zero-carbon park construction solution, offering a practical reference for the green-low-carbon retrofitting and new construction of similar parks across China.

项目背景

当前国家“双碳”战略目标和新型电力系统加速推进，以公共和居住建筑为主体的园区运行能耗与碳排放体量突出，可调资源种类丰富，电气化基础良好，是推进绿色零碳转型、支撑电网稳定运行的关键场景。

园区作为高强度办公与科研活动空间，建筑能耗与碳排放集中；传统园区能源系统以被动用能为主，可再生能源利用不足、供需互动能力弱，难以匹配雄安新区“绿色智慧新城”的高标准定位。主要原因是园区建设缺少统筹清洁能源利用、负荷灵活调节、碳管理的一体化建设思路，尚未形成完整可行的成套实施路径。本项目立足雄安新区绿色低碳发展定位，打造雄安首个落地的全电智慧零碳园区，以“内部降碳、互动降碳、市场降碳、统一集成”的设计理念，通过建设复合式供能技术清洁冷热能源站、全域直流系统、光储直柔配电系统、园区智慧运营管控一体化平台等举措，形成一套可复制、可推广的零碳园区建设方案，为国内同类园区绿色低碳改造与新建提供实践样板。

Project Implementation

The State Grid Energy Internet Industry Xiong'an Innovation Center is located in the northern part of the Internet Industrial Park within the Xiong'an New Area Startup Zone, with a total floor area of approximately 198000m2. The building functions include research and industrial space, testing and inspection facilities, and conference and exhibition centers. Invested, constructed and operated by State Grid Digital Technology Holding Co., Ltd., the project involves a total investment of RMB 2.71 billion. Construction officially commenced in July 2022, and passed internal four-party acceptance in September 2025.

Guided by the design philosophy of “internal carbon reduction, interactive carbon reduction, market-oriented carbon reduction and unified integration”, the project deploys a clean heating and cooling energy station, a full-domain DC system, a photovoltaic-storage-DC-flexibility power distribution system, and an integrated platform for smart park operation and control. It realizes the integrated application of four typical technical features:“clean, energy-efficient and low-carbon, flexible load interaction, coordinated electricity-carbon trading, and smart park operation”.

Clean, Energy-Efficient and Low-Carbon Demonstration - Internal Carbon Reduction: To address high building energy consumption, the technical route of “passive energy saving, active efficiency improvement, clean energy utilization and electric energy substitution”is adopted. This includes: using high-performance building envelopes to reduce heating and cooling loads; enhancing energy efficiency with high-efficiency electromechanical systems and photovoltaic-storage systems; scaling up clean energy supply through rooftop and ground-mounted PV, as well as ground-source heat pumps, complemented by energy storage to improve on-site consumption; leveraging Xiong'an's geothermal and solar resources to advance clean energy utilization; and implementing comprehensive electrification substitution to reduce energy consumption at the source. A park-level energy management and carbon emission monitoring system is also being established to enable online visibility, manageability, and optimization of energy consumption and carbon emissions.

Flexible Load Interaction Demonstration - Interactive Carbon Reduction: To address weak supply-demand interaction, the project builds a park-level hierarchical and zonal coordinated load flexible interaction aggregation platform. It has established a park-level DC grid architecture featuring “four-terminal flexible DC ring network + two-terminal back-to-back DC + one DC zero-carbon building” (with a DC load capacity of 5.6 MW), and a flexible adjustable load of 5.27 MW, accounting for 37% of the park's peak load, enabling proactive response to and deep interaction with the power grid.

Coordinated Electricity-carbon Trading Demonstration - Market-Oriented Carbon Reduction: To resolve the difficulty in monetizing emission-reduction benefits, China's first regional-level “electricity-carbon-certificate” service system is constructed. It connects data links among power consumption, carbon emission reduction and green certificate assets, providing strategic support for enterprises to participate in market-oriented power procurement, carbon trading and demand response, and converts emission-reduction volumes into tradable and verifiable rights and interests.

Smart Park Operation Demonstration – Operational Carbon Reduction: A smart operation brain for the park is developed, alongside a unified integrated service platform for smart operation, management and control, realizing the trinity of smart energy management, intelligent equipment control and panoramic energy-carbon monitoring. The platform supports the park's source-grid-load-storage dispatching system and energy operation management and control, shifting energy-carbon management from passive statistics to active optimization, and supports regional electricity-carbon trading services and demonstration of carbon-reduction achievements.

The project advances in three phases:“planning and demonstration, design and construction, commissioning and evaluation”. In the early phase, top-level zero-carbon design for the park and demonstration of energy and digital solutions are completed. The middle phase covers engineering construction including building energy-saving retrofits, DC distribution networks and the smart platform. The late phase includes system joint commissioning, operation optimization and accreditation through zero-carbon park evaluation.

The park actively promotes green and low-carbon awareness and behavioral advocacy among staff, property management, and visitors. It regularly implements initiatives such as green commuting, office zero-waste programs, and energy-saving and carbon-reduction training, embedding the dual-carbon vision into daily operations and organizational culture, and fostering a shared low-carbon behavioral consensus within the organization.

Project Outcome

Compared with conventional building parks, this project delivers technological innovations in multiple areas, including a clean heating and cooling energy station adopting hybrid energy supply technology, the largest-scale full-domain DC system, and a multi-system collaborative integrated platform for smart park operation:

It delivers an all-electric smart zero-carbon park complying with new national standards, three-star green buildings, and DC-powered zero-carbon buildings with absolute zero energy consumption and zero carbon emissions. The building carbon-reduction rate reaches 63.2 %, and the park-wide carbon reduction rate hits 61.9%. Fully satisfying evaluation criteria for zero-carbon parks and zero-carbon buildings, it is the first national-standard zero-carbon park in China.

2. A full-domain DC system operation mode with three voltage levels of DC750V, DC375V and DC48V is established, forming the “4+2+1” multi-terminal flexible-DC power grid for the park. It addresses challenges such as renewable energy integration, load imbalance across transformer districts and diverse types of DC loads, and builds the largest-scale park-level full-domain DC demonstration with safe and routine operation.

3. A hybrid energy supply technology combining “high-efficiency chillers + ground-source heat pumps + water thermal storage + electric boilers” is applied. A series of tasks have been carried out sequentially, including building load modeling, high-efficiency equipment selection, piping system optimization, energy efficiency simulation of the plant room, and automatic optimization of operation strategies. As a result, the system achieves 100% renewable energy heating, with an annual cooling energy efficiency ratio of 5.58, representing a 59.43% improvement over conventional systems and reaching an advanced level in northern China.
