AbstractAs a centralized area for goods distribution, circulation and processing, logistics parks involve numerous tenants and complex water and electricity usage. Accurate and efficient water and electricity billing management is crucial for controlling operating costs, allocating resources reasonably, and improving tenant satisfaction in the park. The Ankerui Water and Electricity Prepaid Platform, with its intelligent and information-based features, provides innovative solutions for water and electricity billing in logistics parks. This article will elaborate on the design ideas and practical application effects of the platform in a logistics park.

1. Current situation and problems of water and electricity billing management in logistics parks

A certain logistics park covers a large area, including multiple warehouses, office buildings, distribution centers and other buildings, with a large number of tenants and diverse business operations. Before introducing the Ankerui pre paid platform for water and electricity, the management of water and electricity billing in the park faced many problems:

（1）Variable electricity pricing policies，Diverse billing logicThere are various types of parks, including industrial parks, commercial parks, etc. Each type of park has specific energy usage requirements and billing standards. There are various billing logics for energy billing, such as commercial electricity prices, industrial electricity prices, and two-part electricity prices. This requires managers to have a deep understanding of different electricity pricing policies and be able to flexibly respond to the billing needs of different tenants.

(2) Multiple payment methods: Different types of tenants, including private to public and public to public differences. The payment methods include offline payment, WeChat Alipay, bank transfer and other ways, which increases the complexity of financial management and financial docking.

(3) It is difficult to clearly indicate power losses: there are losses in the transmission process of electricity, and it is necessary to accurately calculate and indicate these losses in order to reasonably allocate them to each tenant. However, due to technical and management limitations, it is often difficult to accurately confirm and indicate power losses, resulting in property management having to compensate for losses by increasing electricity prices. This not only increases the burden on tenants, but also puts property management at risk of fines.

(4) Low manual efficiency: Currently, most parks still use manual meter reading methods. There are many buildings in the park, and the scale of enterprises varies. The complexity of the meter reading process also varies, and it takes a long time. The low efficiency of manual meter reading and incomplete energy data result in the inability to calculate and collect electricity bills in a timely manner, leading to interest losses and problems of overpayment and underpayment.

（5）Difficulty in recovering overdue payments: Lack of effective overdue warning and collection methods, serious arrears by some tenants, affecting the turnover of funds in the park.

（6）Lack of energy management: unable to real-time grasp the overall water and electricity consumption of the park and each tenant, making it difficult to formulate targeted energy-saving measures and optimize energy consumption.

2. Policy background

In March 2018, the National Development and Reform Commission issued a notice on reducing general industrial and commercial electricity prices. One is to increase the flexibility of the two-part electricity pricing system; The second is to comprehensively clean up and standardize the charging items of power grid enterprises beyond the transmission and distribution electricity prices, with a focus on cleaning up and standardizing the isolated price increases charged by operators of industrial parks, commercial complexes, etc. to transfer power supply users beyond the national sales electricity prices.

In July 2021, the State Council issued a notice from the National Development and Reform Commission on further improving the time of use electricity pricing mechanism, requiring deepening electricity pricing reform, improving the electricity pricing formation mechanism, promoting green and low-carbon energy development, and further improving the time of use electricity pricing mechanism

The Notice on the Interim Measures for the Collection of Electricity Fees for Non grid Direct Power Supply in 2022 requires that power supply entities such as commercial complexes, industrial parks, property management, and office buildings should collect electricity fees according to the catalog electricity price corresponding to the end user's voltage level, and no other fees should be added to the electricity fee. Determine the end user electricity price based on the "End User Electricity Voltage Level Catalog Flat Section Electricity Price+Floating Range", where the floating range * higher shall not exceed 15%. According to the Electricity Law, if other fees are added to the electricity bill, the violator shall be ordered to return the illegally collected fees and may be fined up to five times the amount of the illegally collected fees
