Holley Technology: Utility meters, AMI systems and prepayment management

Holley Technology supplies electricity, gas and water meters alongside utility data collection and prepayment systems.

Summary

Best for
Utility projects that need smart meters, collection infrastructure and payment or billing workflows.
Less suited to
Selecting a precise meter SKU from broad catalogue descriptions without resolving the published model-code discrepancy.
Deployment
Meters, collectors and head-end software, with ESEP modules for meter data, field data and vending.
Data in
Model-specific electrical measurements and utility-meter data using DLMS/COSEM and selected communication interfaces.

Overview

Holley Technology supplies electricity, gas and water metering equipment alongside collection and utility software. Its catalogue includes smart and prepaid electricity meters, data-collection units and customer displays. The wider range extends to instrument transformers, distribution equipment and energy-storage products, making metering part of a broader power-system offering.

The AMI architecture connects smart meters and collectors to a head-end system. Above that, ESEP brings together meter-data management, field-data management and vending. A utility can therefore compare Holley at both the instrument and system levels: the meter produces readings, while the collection and business software make those readings available for operations and customer services.

Offering

Holley's three-phase smart-meter page describes modular direct-connected, current-transformer and current-and-voltage-transformer versions. The published table gives different current inputs and active-energy accuracy classes for these arrangements. Measurements include active, reactive and apparent energy, voltage, current, power and power factor, with configurable tariff schedules.

The page lists optical and serial interfaces alongside communication-module choices. It currently uses two different model codes in its heading and description, so this profile treats it as a documented product family rather than asserting one exact ordering code. Holley also offers data-collection units for installations that aggregate meter readings before forwarding them to the utility system.

Products and platforms

  1. ESEP / AMI system

    Utility metering software

    Head-end collection with meter-data, field-data and vending modules.1

  2. Prepayment management system

    Utility vending software

    STS keypad/card support, credit-token vending and tariff management.7

  3. LMZ9-0.66 current transformer

    Current transformer

    Epoxy-resin current transformer for systems at 50 Hz and rated voltage up to 0.66 kV.8

  4. Ring Main Unit

    Distribution switchgear

    Switchgear family for ring distribution networks; exact model and communications require a separate specification.8

  5. W113 Large Diameter Ultrasonic Water Meter

    Water meter

    Ultrasonic water-supply metering family with selectable communication interfaces.8

  6. W111 Valve Control Ultrasonic Water Meter

    Water meter

    Ultrasonic drinking-water meter with remote valve control and automatic valve cleaning.8

  7. Commercial Energy Storage System

    Battery storage

    Commercial storage family retained from the current catalogue; configuration-specific capacity and interface are not asserted.8

  8. Residential Energy Storage System

    Battery storage

    Modular residential storage family retained from the current catalogue.8

  9. RS485 to GPRS Data Collector

    Meter data collection

    Collector bridging RS485 field connections and GPRS communications; deployment depends on local cellular service availability.3

    Meter data collection

    Modular concentrator with multiple communication options and local storage.3

  11. High Protection Data Concentrator

    Meter data collection

    Distinct high-protection concentrator family; exact hardware specification should accompany procurement.3

Technology

Holley's AMI documentation names DLMS at the application layer and describes several collection transports, including cellular, power-line and radio options. The three-phase meter's specification separately lists IEC 62056/DLMS COSEM and interface choices. These support a layered design in which the meter protocol and its physical communications module are selected together.

The AMI system provides APIs for external billing and banking services, including data retrieval and prepayment operations. That is a utility application interface, distinct from a local meter connection. The reviewed material establishes manufacturer-described options; it does not establish a tested Edge integration or make every listed communications option standard on every meter.

Markets

Holley's prepayment system serves utilities, residential consumers, commercial and industrial customers, points of sale and back-office systems. Its functions include credit-token vending, tariff and charge management, meter-asset records and transaction reporting. Supported sales channels extend beyond a utility counter to mobile, banking and point-of-sale systems.

The published workflow follows a purchase through the vending service to a token entered at the meter. That makes the offering relevant where customer payment and electricity delivery must be managed together. Its STS keypad and card support addresses a different requirement from an energy dashboard that only displays consumption: the transaction, customer account and meter credit are part of the operating process.

Company

Holley Technology Ltd. identifies itself as a Holley Group member and publishes a Hangzhou address. Its history starts with the establishment of a predecessor enterprise in September 1970. The same timeline records the change from Holley Metering Ltd. to Holley Technology Ltd. in 2015, explaining why both names appear in older metering references.

The history describes a transition from instrument manufacturing towards complete project supply during the 2000s, followed by integrating electricity, water, gas and heat metering with energy-management systems. That development is reflected in today's catalogue, which joins meters, collection units and software rather than presenting the business solely as an electricity-meter manufacturer.
