Acrel-NT Energy and Carbon Management System Solution - Facilitating the Application for Green Factories

 

 

1. Overview of Features

 

This software provides integrated carbon asset management through comprehensive analysis of carbon accounting processes. By establishing logical frameworks based on accounting boundaries, data sources, and industry standards, it systematically organizes functional modules corresponding to business workflows. Detailed descriptions of program functionalities and business designs are included. The system enables comprehensive monitoring of carbon emissions and trading activities, supports transaction decision-making and energy optimization strategies, promotes energy conservation and emission reduction, assists users in acquiring emission-reduction assets, and enhances investment returns.

 

 

 

2. Scope of application

 

1. Applicable to industrial parks, public institutions, high-energy-consuming enterprises, smart factories, and other fields.

 

2. It can be integrated into systems such as EMS, EIoT, and industrial energy consumption monitoring, functioning as a carbon asset management module to assist users in energy management.

 

 

 

3. Term definition

 

(1) Carbon assets: Emission allowances, carbon credits (the measurement unit of carbon credits, where 1 carbon credit equals 1 ton of CO₂ equivalent), and related activities. These assets can be either tradable or held as reserves. Examples include: government-allocated carbon emission allowances; carbon emissions reduced through energy-saving technological upgrades; and emission reduction credits generated from projects traded or transferred in carbon markets.

 

      (2) Carbon Footprint: The carbon consumption of enterprises or individuals in transportation, food production and consumption, and various production processes. Manufacturing supply chains typically involve procurement, production, warehousing, and transportation, with warehousing and transportation generating significant carbon dioxide emissions. The more carbon is consumed, the more CO₂ is produced, resulting in a larger carbon footprint; conversely, a smaller carbon footprint indicates reduced emissions.

 

 

 

(3) Nationally Certified Voluntary Emissions Reductions (NCCVRE): Quantified and certified greenhouse gas emission reductions from projects in China, including renewable energy, forestry carbon sinks, and methane utilization, registered in the National Greenhouse Gas Emission Reduction Trading Registry.

 

     (4) CCER: A carbon trading mechanism for emission reductions in future carbon exchanges. For example, the government allocates 1 million tons/year of emission allowances to two companies, A and B. Company A achieves its target through energy-saving upgrades, emitting only 800,000 tons of CO₂. The surplus 200,000 tons can be sold on the carbon market to generate profits. Company B, however, faces greater challenges in upgrades and emits over 1.2 million tons by year-end, exceeding the 1 million-ton quota. In this case, it must purchase 200,000 tons of allowances from the carbon market to meet the policy requirements.

 

 

(5) Carbon Quotas: Approved by local development and reform commissions, enterprises are granted a "legal" cap on greenhouse gas emissions for a specified period. This cap constitutes the quota. If actual emissions exceed the quota, the excess must be purchased; if emissions fall below the quota, the surplus can be sold on the carbon trading market. This mechanism functions as a special form of government-issued "currency." Each year, the government allocates a fixed sum to emission-controlled enterprises. By reducing emissions, companies can save this "money" and resell the savings to other enterprises in need—this is known as carbon finance.

 

    (6) Carbon accounting boundaries: The scope defined when calculating carbon emissions. Carbon accounting requires consideration of various emission sources, including direct and indirect emissions. Direct emissions refer to a company's own carbon output, such as energy consumption during production and waste disposal. Indirect emissions encompass emissions generated through the company's supply chain, including those from suppliers and customers.

 

 

4. Platform Function Guide

 

1. Project-linked accounting model

 

  Go to the Basic Data Management-Project Management menu, select a created project, and click the [Accounting Model Binding] button. Choose an industry or region, and all facilities under that industry will be displayed by default. You can edit or add custom facilities. See Figure 1-1, 1-2, and 1-3.

graph 1-2

 

graph 1-3

 

*Note: For individual projects, you can add or remove facilities in the project management interface for accounting model binding without affecting data already bound to other projects.

 

 

2. Add emission reduction plan

 

The project adds annual emission reduction plans, setting the total carbon emission quota and reduction ratio for the year. It automatically calculates the projected carbon emissions, helping enterprises verify compliance in subsequent reports and analyses, as shown in Figure 4-1.

 

 

graph 2-1

 

 

3. Add quota assessment

 

Carbon emission thresholds with specified dates are set for each accounting facility. After completing the carbon inventory, these thresholds automatically compare against actual emissions to trigger abnormal emission alerts, as shown in Figure 4-1.

4. GHG activity data collection

 

1. automatic continuous data acquisition

 

① On the project-linked accounting model page, edit the corresponding facility, select the energy sub-item, and bind the topological node to the corresponding device (the energy consumption topological node is already bound to a device). As shown in Figure 4-1.

 

graph 4-1

 

 ②Click the "Energy Carbon Platform-GHG Activity Data Collection" menu, select a project, and the system will display all facility categories linked to that project in tab form. Switching between categories shows the platform's calculated cumulative energy consumption. Manual input or editing is not supported, as shown in Figure 4-2.

 

graph 4-2

 

*Note: The platform does not calculate energy consumption in real time. The energy consumption displayed on this page may differ from the actual energy consumption generated by the device.

 

 

2. Export Data

 

Switch to the tab, click the [Edit] button, and manually enter and save the data. Fire extinguishers, refrigeration equipment, and WD-40 only support annual entry, while others support annual or monthly entry. As shown in Figure 4-3.

 

graph 4-3

 

*Note 1: Monthly data will be automatically accumulated when queried annually

*Special Note 2: When the device statistics type is set to [Fill Method], enter the actual fill amount. See Figure 4-4.

5. Carbon inventory

 

1. query and pivot

 

Select the project and year, then click the [Query] button. The backend will automatically calculate greenhouse gas emissions based on the entered activity data. The page displays the total carbon emissions, category 1 emissions, category 2 emissions, and detailed greenhouse gas totals for each category. You can expand or collapse the greenhouse gas emissions for each facility. See Figures 5-1 and 5-2 for details.
