Gas Natural, Spain
Architecting the Solution
Gas Natural selected historic cities of Lorca and Mula in the province of Murcia in Southeastern Spain for deploying pilot projects using Nuri's ZigBee compliant AiMiR wireless mesh network AMI. The two sites selected, were a good mix of crowded urban areas where gas distribution was well established and the areas where customer density was low and gas was recently supplied.
The main objective behind pilot projects was to validate systems viability, ease of installation and operation and viability of mass deployment of Nuri's AMI system in residential areas throughout the country.
Working in close collaboration with Gas Natural and keeping their requirements in mind, Nuri architected an end-to-end, two-way AMR communications system enabling Gas Natural to remotely read individual meters at any time on demand. The solution was designed to remotely collect metering data periodically from its 5,000 residential customers in the cities of Lorca and Mula in Southeastern Spain using Nuri's AiMiR ZigBee compliant 2.4GHz wireless mesh AMI (Advanced Metering Infrastructure) technology. The system was designed with the utmost flexibility to support already in place gas meters. Gas Natural decided to use GPRS wireless network to backhaul meter data to the AiMiR Head End servers located at its control centers.
The following items were considered in architecting the solution:
Nuri's AiMiR AMI system solution consists of:
Achieved over 99% of daily meter read and nearly 100% of monthly meter read
The pilot deployment was divided into three phases to ensure that it meets Gas Natural desired objectives as mentioned earlier. In the first phase Nuri's AiMiR AMI system was tested in the libratory environment to validate systems conformance to the target specifications. During the second phase, a test pilot was setup to achieve small-scale validation involving system reliability, installation, and operation over two to three-month period. Upon successful completion of phase 2, phase 3 was initiated to demonstrate systems performance and reliability, installation and maintenance procedures, direct involvement of Gas Natural personnel, and the integration of AMI with business processes, extending AMI to 4,500 customers.
The following benefits were successfully demonstrated as a result of the pilot deployment:
