China Energy Storage Network News: The cumulative number of registered users has exceeded 60,000, 23,000 energy-consuming enterprises have settled in, and 838 service providers have been carefully selected... On November 30, 2021, the "Green State Grid" was connected with the smart energy service platform of 27 provincial power companies of State Grid Corporation of China. So far, the "Green State Grid" has pushed a total of 1.1776 million comprehensive energy efficiency diagnosis reports and provided clean energy, green energy and smart energy services to 325,600 users.

As the unified Internet portal for the company's integrated energy service business, since its launch in September 2020, "Green State Grid" has relied on the company's brand advantages and massive user resources to deeply explore the value of power data, build an Internet sharing platform, break down information barriers, empower relevant entities in the integrated energy service field, and promote the online and offline integrated development of the integrated energy service system.

Focus on "power supply + energy efficiency services" to help enterprises intuitively understand energy consumption

On January 5, Xiong Anjun, manager of Chongqing Iron and Steel Research Institute Co., Ltd., received a comprehensive energy efficiency diagnosis report for last month pushed by "Green State Grid". The report analyzed the company's energy consumption from the dimensions of energy consumption overview, clean energy consumption, economic energy consumption, and smart energy consumption. "This diagnosis report helps me to clearly and intuitively understand the company's energy consumption situation, which is very practical." Xiong Anjun left a message on the "Green State Grid" client.

The comprehensive energy efficiency diagnosis report is one of the basic service functions provided by "Green State Grid" to users. After the enterprise registers with "Green State Grid" and binds the electricity account number, it can see the enterprise's exclusive comprehensive energy efficiency diagnosis report in the "Enterprise Energy Consumption" section on the homepage. The report can clearly show the user's energy consumption trend, green electricity consumption, energy consumption level per unit building area, participation in electricity trading, demand response, etc., and let users have a deep understanding of their own energy consumption in the form of data and charts.

Relying on comprehensive energy efficiency diagnosis reports, "Green State Grid" can accurately analyze the potential comprehensive energy service needs of enterprises in the fields of comprehensive energy efficiency, multi-energy supply, clean energy and emerging energy use, and recommend service providers, solutions, cases, products and services gathered on the platform to enterprises, helping enterprises improve their energy efficiency management level.

On October 28, 2021, the customer service team of "Green State Grid" received an inquiry from Lintou Dagui Foundry in Hanshan County, Anhui Province about distributed photovoltaic installation, photovoltaic equipment manufacturers and investment returns. Previously, "Green State Grid" pushed a comprehensive energy efficiency diagnosis report to the factory and recommended that the company install distributed photovoltaic power generation equipment or actively participate in green electricity trading. The "Green State Grid" operation specialist also provided professional answers to the company from the aspects of photovoltaic overall structural knowledge, design planning, effect evaluation, etc., and comprehensively considered the user's location and building energy consumption, and formulated a 1,500-kilowatt distributed photovoltaic low-voltage grid-connected technical solution.

"We will use the comprehensive energy efficiency diagnosis report as a starting point to continuously improve the accuracy and practicality of the report, strengthen data governance, and accelerate the construction of user-side energy perception layers such as building energy optimization, so that the comprehensive energy efficiency diagnosis report can create greater value for users and play a more important role in improving energy efficiency." Zhou Bing, deputy general manager and party committee member of State Grid Integrated Energy Services Group Co., Ltd., introduced.

Since its launch, "Green State Grid" has provided energy efficiency services such as energy efficiency management and intelligent operation and maintenance to 1.8 million users.

Use market-oriented means to regulate and guide users to use energy intelligently

"After receiving the demand response invitation, we adjusted the production process in a timely manner. Not only can we get the response subsidy, but also reduce electricity bills during off-peak hours. The implementation of demand response is not long and has little impact on overall production. It can be said that we kill two birds with one stone." said the person in charge of Wuhan Lidao Property Management Co., Ltd. In July 2021, the company passed the "Green State Grid" registration and certification to become an agreement user, agreeing to provide 15,000 kilowatts of demand response capacity.

Demand response is a market-based means of regulating electricity supply and demand. The company has implemented demand-side management in depth, continuously improved the demand response policy mechanism, and guided and encouraged power users to adjust their production plans and actively reduce peak loads and fill valleys through market price signals such as time-of-use electricity prices or incentive mechanisms such as financial subsidies. While ensuring the stable operation of the power grid, it promotes the consumption of clean energy and helps society save energy and reduce consumption. "Green State Grid" has realized the full process of demand response business management, including user declaration, startup management, response execution, execution monitoring, effect evaluation, subsidy management, and statistical reporting, and promoted the digital transformation of demand response business.

During the peak summer period in 2021, the "Green State Grid" signed demand response agreements with 1,419 enterprises in Hubei, aggregating 2.8895 million kilowatts of adjustable loads, forming a demand-side mobile peak-shaving capacity of 5% of the maximum power load. A total of 5 demand responses were carried out, regulating 63,900 kilowatts of load, and helping to ensure stable operation of the power grid during peak load periods.

On September 24, 2021, the Gansu Provincial Department of Industry and Information Technology issued the "Notice on the Trial Implementation of Electricity Demand Response Work", organizing eligible users to participate in demand response through online applications on the "Green State Grid", and using government documents to clearly define "Green State Grid" as a platform for enterprises to apply online and participate in demand response.

Taking serving the goals of carbon peak and carbon neutrality as the starting point, the "Green State Grid" innovatively explores value-added businesses such as microgrids, carbon trading, market-based electricity sales agency, and green electricity procurement, and collaborates with provincial power companies to jointly cultivate and create emerging business forms such as intelligent operation and maintenance, shared electricians, and electricity operation and maintenance.

On December 2, 2021, the first operation information of the newly installed electric boiler equipment of No. 135 Middle School in Urumqi, Xinjiang was successfully uploaded to the provincial smart energy service platform of State Grid Xinjiang Power, and the data was connected with the "Green State Grid". The school's boiler operation and maintenance personnel can log in to the "Green State Grid" to view the school's energy overview, energy trend analysis, equipment energy consumption and other data and comprehensive energy efficiency diagnosis reports, and scientifically allocate equipment operation in combination with the campus schedule.

At present, the "Green State Grid" has integrated 165 provincial smart energy service platform micro-applications, formed a broad interconnected architecture system, and constructed service scenarios such as energy efficiency management, intelligent operation and maintenance, energy hosting, carbon trading agency, adjustable load aggregation and demand response, providing users with one-stop energy services.

Enhance collaboration among enterprises and create a mutually beneficial and win-win industrial system

On the afternoon of December 17, 2021, relevant persons in charge of Jiangsu Leibo Electric (Suzhou) Co., Ltd. consulted on the "Green State Grid" platform about the filing, construction, operation and maintenance of distributed photovoltaics. According to the needs of the other party, the "Green State Grid" customer service team assisted users in establishing a communication channel with Suzhou Power Supply Company and recommended qualified service providers on the platform.

Integrated energy services are characterized by multiple energy forms, multiple user types, multiple professional fields, and a long business chain. No single service provider can fully rely on its own strength to provide comprehensive support for the business and comprehensive services to users.
