ADD Grup together with Eximprod Power Systems began deliveries under a contract for 620 000 smart meters for Distributie Energie Oltenia (DEO) in Craiova, Romania.
ADD Grup together with Eximprod Power Systems won the tender for 620 000 smart meters due to the best ratio of pricing policy and excellent proven quality. The project includes 550 000 single-phase smart meters, 67 000 three-phase smart meters and 3 000 data concentrators. The companies have already started the implementation under the signed contract.
The data transmission technology, as in the majority of the projects delivered by ADD Grup, is based on PRIME version 1.3.6, which has proven its practicality and efficiency in more than 22 million smart meters installed around the world. All smart meters are supplied with an integrated PLC modem and with the ability to upgrade to PRIME 1.4 in the CENELEC and FCC bands replacement of firmware, as well as with an RS-485 interface and support for a 3GPP communication module with the ability to install a modem without removal of the smart meter, which gives DEO flexibility in transferring customers from the category of energy consumers to the category of prosumers.
This project is one of the additional stages of DEO’s grid modernization strategy. By updating the consumption monitoring system, the reliability of the power grid also increases. In the event of a breakdown/ outage or energy loss in the grid, the problem is immediately detected, which leads to its quick elimination, due to 100% registration and more than 98% data collection of ADD Grup smart meters. Thus, DEO tries to ensure an uninterrupted power supply to its end customers, 24/7.
The deployment of smart meters from ADD Grup is part of a complex implementation of an AMI solution, including data concentrators and integration with head-end software. ADD Grup smart meters are fully compatible with the third-party devices also based on the PRIME standard, and in the future, they can be seamlessly integrated with other devices, which will allow DEO to continue modernization and expansion of the power grid without any obstacles.
Through the technical improvement of the power grid, DEO strives to increase network capacity bandwidth to connect new consumers, reduce technical and commercial energy losses, assure power quality and satisfy the growing demand from the existing consumers.
This is the third project that ADD Grup delivers to DEO. The first one was deployed in 2017 and served as the basis on which was DEO formed its concept for technologies understanding and defining the strategy for the deployment of the smart meters in Romania. The results of the project are excellent evidence of the fact that DEO’s decisions were correct and well-thought. The second project delivered by ADD Grup was successfully implemented in 2020, the deployment of 10 000 smart meters.

About PRIME Alliance
PRIME (PoweRline Intelligent Metering Evolution) Alliance AISBL was created in 2009 to define an open and future-proofed communications PLC-based infrastructure to support large scale smart metering and other smart grid deployments. The PRIME Alliance has attracted key industry players, including Sponsoring Members El Sewedy, ZIV, Renesas and Corinex. The goal of the Alliance is to provide a framework in which the smart metering and smart grid industry have access to open detailed technical specifications in order to develop fully interoperable solutions, allowing multiple vendors to be operational within the same distribution network in one common system architecture. Detailed technical specs include Physical PHY layer and Medium Access Control MAC layer specifications.
The PRIME Alliance provides a forum for the definition, maintenance and support of an open and comprehensive standard for narrowband power line for Smart Grid products and services. The mission of the Alliance is to accelerate the demand for products and services based on this worldwide standard and promote the broad adoption and use of the specification while certifying multi-vendor interoperability and compatibility with the global standard. The Alliance is open to all potential partners who agree to actively support and promote an open and public specification for the benefit of the end-user and all industry stakeholders.
