[quote] The pilot formed part of a cost benefit analysis (CBA) for large scale smart meter deployment in Lithuania. [Smart meters Lithuania: ADD GRUP wins place in pilot]
According to a release, a previous CBA (done without participation of ADD GRUP) in 2012 had negative results, leading to halted smart meter installations in Lithuania.
The AMI solution deployed comprised more than 3,000 smart electricity meters, data concentrators and head-end system. Communication technologies employed include PLC PRIME v.1.3.6 as the primary communications technology and 3GPP (2G/3G) communication as a back-up solution for specific field conditions.
ADD GRUP was responsible for the supply of data concentrators, head-end systems, and auxiliary equipment. It also customised its ADDAX AMI solution for the purpose of the pilot. Project partner and prime contractor Tecnolinės UAB managed the installation, operation and maintenance of the deployment.
ADDAX AMI solution
The release adds that while project requirements and conditions were complex, ADD GRUP proceeded in its usual manner by tailoring its solution to customer needs, and at the same time keeping the support for open protocols.
KPI requirements and a snapshot of system performance include:
- 97% of the data from 00:00 till 24:00 in the (N) day should be collected at 08:00 of (N+1) day;
- 99% of the data recorded by the smart meters from 00:00 till 24:00 in the (N) day should be collected at 24:00 of (N+2) day;
- 100% of the data recorded by the smart meters from 00:00 till 24:00 in the (N) day should be collected at 24:00 of (N+4) day;
The KPIs relate to the following data types: 15 minutes, daily and billing profiles as well as power quality indicators, events and instantaneous values.
ADD GRUP claims the pilot project proves once more that the ADDAX solution performs in line with the toughest customer expectations.
“[The] goal has been to provide reliable AMI communications, so that the CBA would not be influenced by issues related to AMI communications or any other system related issues. This way, ESO would not be concerned with AMI system performance, but instead focus on its main tasks of working with its customers, advertise the use of new, flexible tariff plans and so forth.
“Based on the results of the CBA, Lithuanian DSO – ESO – will decide on the further large scale implementation of smart meters in Lithuania.”
