Electricité de Tahiti chooses Astec for Complete GIS system implementation

Electricité de Tahiti (EDT) is an electric company that owns the public electricity service in French Polynesia. EDT is involved in the production and distribution of electricity in Tahiti and other islands of French Polynesia and has been on the market since 1987.

Challenge

GE Digital Energy commissioned Astec to implement a complete GIS system for EDT based on Smallworld NRM Electricity. The size and complexity of the project were daunting and required careful planning; 27 GB of data in the resulting Smallworld database and more than 30 APIC object types mapped on over 30 NRM Elec tables.

Solution

The project started with the building of a working prototype demonstrating Smallworld’s potential to the customer in conjunction with the customer’s own data. Once the proof of concept was accepted, we started the data migration process. It wasn’t an easy task as the former GIS system did not provide a flexible interface. We managed to achieve satisfying data quality by developing a dedicated migration framework and postprocessing procedures. After installing Smallworld in an out-of-box fashion and configuring it, we started the customization process. Many additional features and interfaces were required by the customer. We managed to provide a turnkey solution thanks to close cooperation with GE and EDT.

Results

Astec had to support the customer in every phase of system implementation. From business process mapping and system functionality design, through execution and delivery, to after-deployment services and support.

The customer fully accepted the delivered solution, and all work was completed on time with the best possible quality. Moreover, Astec was responsible for maintenance and support services for EDT and implemented new features into the system (per change requests).
