2026年5月28日，京新高速尖头山隧道独立构网微电网项目正式并网投运。张家口高速公路发展有限公司(以下简称张家口高发展公司)联合石家庄皓平新能源科技有限公司、河北楚恒建设工程有限公司相关负责人齐聚现场，共同见证这一张家口市首个高速公路隧道风光储一体化独立构网标杆示范工程落地见效。

On May 28, 2026, the independent grid-connected microgrid project of the Jingtianshan Tunnel on the Jingxin Expressway was officially put into operation. The Zhangjiakou Expressway Development Co., Ltd. (hereinafter referred to as Zhangjiakou High Development Company) jointly with the relevant responsible persons of Shijiazhuang Haoping New Energy Technology Co., Ltd. and Hebei ChuHeng Construction Engineering Co., Ltd. gathered at the site to jointly witness the implementation of this first highway tunnel integrated project of wind, solar, storage and independent grid connection in Zhangjiakou City.

作为河北交投集团在交通与新能源融合领域的突破性实践，为高速领域绿色转型注入强劲动能，标志着我省高速公路能源供给体系向自主化、智能化、低碳化迈出关键一步。

As a pioneering initiative by Hebei Expressway Investment Group in the integration of transportation and new energy, it has injected strong impetus into the green transformation of the expressway sector, marking a crucial step towards the autonomy, intelligence and low-carbonization of the energy supply system for our province's expressways.

张家口高发展公司创新采用独立构网运行模式，深度挖潜隧道沿线闲置空间资源禀赋，通过市场化招商引资模式落地实施，真正实现项目建设零财政投入、长期运营零额外成本，大幅降低高速公路绿色能源升级的资金门槛。

The Zhangjiakou High Development Company has innovatively adopted an independent grid operation model. It has deeply explored and utilized the idle space resources along the tunnel, and implemented it through a market-oriented investment attraction model. This has truly achieved zero fiscal investment in project construction and zero additional costs for long-term operation, significantly reducing the financial threshold for the upgrading of green energy on expressways.

该项目集成分布式光伏、小型风电、储能系统、智能能源管控四大核心模块，形成“源网荷储”一体化绿色供能体系，整体装机配置达620KWp。依托自主研发的源网荷储一体化智能调度系统，项目可实现能源精准调配、稳定可控供电：不仅能满足隧道日常照明、通风等运营用电需求，更能在极端天气、电网故障等应急场景下，全方位保障隧道监控、应急照明等核心负荷不间断供电，有效筑牢高速公路安全保通防线。

This project integrates four core modules: distributed photovoltaic power generation, small-scale wind power generation, energy storage system, and intelligent energy management control. It forms an integrated "source-grid-load-storage" green energy supply system, with a total installed capacity of 620KWp. Relying on the independently developed integrated intelligent dispatching system for source, grid, load and storage, the project can achieve precise energy allocation and stable, controllable power supply. It not only meets the daily lighting, ventilation and other operational power demands of the tunnel, but also can provide uninterrupted power supply for core loads such as tunnel monitoring and emergency lighting in emergency scenarios like extreme weather and power grid failures, effectively strengthening the safety and smooth operation defense line of the expressway.

在绿色节能成效上，该项目年均可提供绿色电能170万度，隧道绿电替代率达49.8%(接近50%)，彻底打破传统高速隧道依赖市电单一供电的格局，为高速公路隧道智慧化、低碳化供能提供成熟可行的先行方案。

In terms of the effectiveness of green energy conservation, this project can provide 1.7 million kilowatt-hours of green electricity annually. The green electricity substitution rate in the tunnel reaches 49.8% (close to 50%), completely breaking the traditional pattern where high-speed tunnels rely solely on grid power for power supply. It provides a mature and feasible pioneering solution for the intelligent and low-carbon energy supply of highway tunnels.

项目运营周期25年，经济、生态、社会三重效益十分突出：

The project's operational period is 25 years, and it demonstrates remarkable economic, ecological and social benefits.

经济效益：年均节省电费约40.36万元，电费节约率近25%，全周期累计可节约用电成本超1009万元，降本增效成果显著;

Economic benefits: Annual savings in electricity costs amount to approximately 403,600 yuan, with an electricity cost saving rate of nearly 25%. Over the entire period, cumulative electricity cost savings exceed 10.09 million yuan, demonstrating significant cost reduction and efficiency improvement results.

生态效益：年均节约标准煤276.07吨，年均减排二氧化碳839.16吨，持续减少交通领域能源消耗与碳排放，为区域生态环境保护贡献交通力量;

Ecological benefits: On average, 276.07 tons of standard coal are saved annually, and 839.16 tons of carbon dioxide are reduced annually. Continuous reduction of energy consumption and carbon emissions in the transportation sector contributes to the protection of the regional ecological environment.

社会效益：大幅提升高速公路防灾减灾、应急保通能力，有效补齐高速隧道应急供电短板，为公众出行安全保驾护航。

Social benefits: Significantly enhance the disaster prevention and mitigation, emergency traffic restoration capabilities of expressways, effectively address the shortcomings in emergency power supply for expressway tunnels, and ensure the safety of public travel.

此次并网投运的尖头山隧道微电网项目，以独立构网技术为核心支撑，以闲置资源盘活为实施路径，以“零投入、低成本”为核心优势，以绿色低碳、安全高效为发展目标，成功探索出高速公路能源自主化升级的新路径。

The Xianoutianshan Tunnel Microgrid Project, which was put into operation this time, is supported by independent grid connection technology as its core, implemented through the utilization of idle resources, and has the core advantages of "zero investment and low cost". Its development goal is to achieve green, low-carbon, safe and efficient energy autonomy for expressways. This project has successfully explored a new path for the autonomous energy upgrade of expressways.

作为全国高速交通领域的创新实践，该项目不仅为张家口高速领域交能融合提供了可复制、可推广的实践样本，更以河北交投集团的先行探索，为全国高速交通领域新能源融合应用、低碳转型发展贡献了河北智慧与河北方案。未来，张家口高发展公司将继续深化交通与新能源融合创新，推动更多绿色低碳项目落地，助力交通强国建设与“双碳”目标实现。

As an innovative practice in the national high-speed transportation sector, this project not only provides a replicable and scalable practical sample for the integration of energy and transportation in the Zhangjiakou high-speed sector, but also, through the pioneering exploration of Hebei Transportation Investment Group, contributes the Hebei wisdom and solutions to the application of new energy and the low-carbon transformation in the national high-speed transportation sector. In the future, the Zhangjiakou High Development Company will continue to deepen the integration innovation of transportation and new energy, promote the implementation of more green and low-carbon projects, and contribute to the construction of a transportation-strong country and the realization of the "carbon neutrality" goal.
