Brazilian power utility CPFL and Silver Spring Networks have extended their partnership to further development of CPFL’s distribution automation programme. [quote] CPFL will leverage Silver Spring’s IPv6 platform to connect over 3,700 reclosers to provide reliability for what is believed to be one of the world’s largest geographic distribution automation deployments.

The partners are working to expand CPFL’s distribution automation programme over 100,000 km2 of São Paulo State, Brazil, which is estimated  to cover 305 cities. [Singapore Power to deploy IoT platform]

According to a release, CPFL’s programme is built upon Silver Spring’s IPv6 platform deployment for advanced metering infrastructure for ‘Grupo A’ customers in the region.

The CPFL programme will expand on its current deployment of 640 reclosers to connect an additional 3,700 reclosers, helping to improve service reliability for consumers, while speeding up fault detection and accelerating system restoration.

Caius Vinicius Malagoli, engineering director, CPFL Energia, said: “As part of the CPFL technology infrastructure modernisation programme, we have focused a large proportion of our investment on this smart grid program. CPFL’s success leading the first commercial-scale smart grid deployment in Brazil is based on the Silver Spring IPv6 network platform, whose benefits are already apparent to our customers.”

Operational efficiency with smart grid

CPFL aims to increase network reliability, speed up response times, and optimize its field operations. According to CPFL, the platform will replace CPFL’s cellular-based GSM solution, which offered less than 80% coverage and required monthly service fees. As a result, CPFL expects to realise performance, operational and reliability benefits including:

  • Faster restoration response times through the high-availability control and supervision offered by the distribution network reclosers.
  • Optimisation of on-site team provisioning, mainly during massive energy outages.
  • Increased coverage, reliability and security at a lower total system cost based on Silver Spring’s IPv6 wireless networking and solutions platform.

“CPFL leads the Brazilian energy sector with the deployment of its smart grid, which improves network operational efficiency, benefitting CPFL’s industrial and commercial customers and their residential users,” said Gadner Vieira, general manager, Silver Spring Networks Brazil.
