E-REDES is Portugal’s largest distribution system operator (DSO), delivering power to over 6 million consumers. DSO needed to update an obsolete legacy VHF system at 1,083 remote substations nationwide. The legacy system presented quality shortcomings, with communication lag between substations. Westermo put a big focus on gaining an in-depth understanding of the customer’s specific needs and circumstances, resulting in producing an innovative solution that was more efficient and accurate than the customer’s original inquiry—a major contributor to the good relationship and trust between the parties.
In 2022, Westermo supplied E-REDES with an all-new cellular communication network (approx. 800 4G/LTE routers) for telemetry between the central SCADA system and substations. The solution enabled a significant improvement in system reliability and response time, but also increased future expansion capacity. Virtual Access, acquired by Westermo in 2019, had previously supplied E-REDES with 20,000 cellular routers for smart metering.
“Westermo’s products were critical in supporting communication between our SCADA system and remote telemetry units (RTUs), enabling faster action on the grid and superior quality of service for consumers. This has been a very rewarding, transparent and uncomplicated partnership, enabling us to solve technological problems and satisfy our needs quickly and securely.”
