ADD Grup: Electricity and water metering with utility communication systems

ADD Grup makes electricity and water meters, communication equipment and submetering services for utilities, hotels and rental properties.

Best for: Utility AMI projects and property submetering that need meters, communications and collection software.
Less suited to: A simple industrial Modbus retrofit selected without a utility or property collection architecture.
Deployment: ADDAX electricity or ADDRA water meters connected through the selected utility network; ADDERRA serves property submetering.
Data in: Electricity consumption and water volume from its metering products.
Pricing: Pricing was not established from the reviewed technical sources; request a quote for the exact configuration.

Overview

ADD Grup develops electricity and water metering equipment together with the communications used to collect readings. Its company overview distinguishes ADDAX electricity meters, ADDRA water meters and the ADDERRA submetering service. These are related offers for different users, rather than three names for a single instrument.

The current website positions ADDAX around utility metering and ADDERRA around hotels and rental property. ADDRA adds ultrasonic water measurement, including versions associated with shut-off valves. This breadth matters when comparing suppliers: electricity billing, tenant consumption and water leakage management require different field equipment even if their readings eventually appear in a common monitoring system.

Offering

The ADDAX development history describes successive generations of smart electricity meters, including changes in their communication technology. The company explains that it moved from proprietary communications toward PRIME and G3-PLC and developed a universal hardware platform able to support those alternatives. That history should be read as a description of particular generations and projects, not a promise that any old meter can accept any modern network.

Alongside electricity products, the current portfolio includes ultrasonic ADDRA water meters with separate or integrated shut-off valve arrangements. ADDERRA combines metering with a smartphone application and payment workflow for property submetering. Those offerings address service and account management as well as the underlying measurement.

Technology

ADD Grup's communication portfolio separates pure power-line communication, hybrid PLC and radio, and cellular approaches. This is useful in utility networks because the communication medium is part of the deployment design: meters on a low-voltage network can have different collection requirements from isolated premises or meters located where radio coverage is difficult.

Its Latvian project account describes deployment with ELKO and AS Sadales tīkls, including a later G3-PLC pilot using meters that had operated with PRIME. The concrete example is more informative than assuming universal protocol interchangeability. It shows why installed hardware generation, firmware and head-end requirements belong in an AMI comparison alongside the name of the communication standard.

Markets

The reference-project collection describes utility deployments in several countries and identifies partners, network operators and communication choices. Its Polish accounts cover work with Energa Operator using S-FSK and later PRIME meters. The Latvian account addresses a change in communication technology within an existing deployment. These examples illustrate the company's emphasis on large meter populations and collection infrastructure.

The ADDERRA offer serves a different commercial setting: hotels and rental property owners managing electricity or water consumption and prepaid accounts. That distinction helps buyers frame a request. A utility AMI rollout involves network-wide operations and head-end integration, while property submetering also needs tenant access, account allocation and payment handling.

Company

ADD Grup's company timeline identifies 1992 as its incorporation date and 1998 as the start of smart digital meter development with integrated power-line communication. It records a licensing agreement in 2004, PRIME meter certification in 2013, a universal platform in 2014 and a hybrid solution in 2019. These milestones describe the company's progression from metering hardware toward networked measurement systems.

The published company address is in Chisinau, Moldova. Its current portfolio retains the ADDAX name for electricity metering while extending into water through ADDRA and property services through ADDERRA. The timeline's 2022 ultrasonic-water-meter milestone provides a specific link between that newer product line and the longer-established electricity business.
