CASE STUDY: Energa Operator was the first utility in Poland to implement a massive rollout (Stage One) of smart meters, confirming its position as a leading investor in the Polish distribution system. The deployment took place in 2012, when Energa Operator installed 109,000 smart meters delivered by ADD GRUP as a first stage of rolling out advanced metering infrastructure (AMI).
Implementing AMI into grids
This case study describes main challenges for Stage One implementation and illustrates organisational efforts needed to make an AMI project successful. It is especially relevant for other distribution system operators in Poland, to help them manage the implementation of AMI into their grids from defining specifications to organising technical dialogues, selection, managing the installation, commissioning and day-to-day operation of AMI system.
Background to the rollout
Following a series of AMI pilot projects conducted during 2007-2011, involving about 23 000 smart meters from 12 vendors, Energa Operator made a decision for AMI rollout.
The first stage of rollout involved implementing 109, 000 smart meters based on S-FSK IEC 61334-5-1 communication technology. The project has been divided into three parts: Zone A – Head End System; Zone B – 3GPP/CDMA modems for ensuring connection between Zone A and Zone C; and Zone C – data concentrators and balance meters and residential meters manufactured and supplied by ADD GRUP.
The goal of such division, where different segments of AMI system are provided by independent suppliers, was to secure the utility from vendor lock-in and to have a better negotiating position. All solutions are interoperable and have well-defined interfaces to ensure easy integration.
