Silver Spring expands DA programme in Brazil

At this month’s Sendi Brazil conference, Silver Spring Networks and CPFL Energia, Brazil’s largest private-sector electricity company, announced the expansion of its distribution automation (DA) programme.
Covering 305 cities across more than 100,000km² of CPFL’s service territory in São Paulo state, the programme is believed to be one of the world’s largest DA deployments when measured by service territory, and is built upon California-based Silver Spring’s IPv6 platform deployment for advanced metering infrastructure for Grupo A customers in the region.
The programme will expand on CPFL’s current Silver Spring deployment of 640 reclosers to connect an additional 3700 reclosers, helping to improve service reliability for consumers, while speeding up fault detection and accelerating system restoration.
“As part of the CPFL technology infrastructure modernisation programme, we have focused a large proportion of our investment on this smart grid programme,” said Caius Vinicius Malagoli, engineering director for CPFL Energia. “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.”
By implementing Silver Spring’s two-way platform for smart grid applications, CPFL aims to increase network reliability, speed up response times and optimise its field operations.
“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 for Silver Spring Networks in Brazil. “We are very excited to be able to support CPFL as it leverages the existing platform to expand these improvements throughout its coverage area and extend the benefits of smart grids to its customers.”
The platform will replace CPFL’s cellular-based GSM network, which offered less than 80 per cent 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, and optimisation of on-site team provisioning, mainly during massive energy outages. There could also be increased coverage, reliability and security at a lower total system cost based on Silver Spring’s IPv6 wireless networking platform.
At last week’s European Utility Week in Barcelona, Silver Spring Networks signed a development agreement with Kamstrup, a supplier of intelligent metering for energy and water consumption owned by Danish energy company OK. Kamstrup will integrate Silver Spring’s standards-based IPv6 Gen5 platform and Kamstrup’s Omnipower electric meter series to help increase speed to market for smart energy in Emea, Latin America and Asia Pacific.
“We were drawn to Kamstrup’s experience in understanding the challenges facing the power utility industry in different regions, and their triangulation on customers, production and development to enable rapid innovation,” said Eric Dresselhuys, co-founder of Silver Spring Networks. “We look forward to working with Kamstrup to expand on our mission to connect things that matter the most.”
The Gen5 platform offers speeds up to 2.4Mbit/s, simultaneous mesh communications on both sub-gigahertz and 2.4GHz frequencies, integration of 4G LTE communications, and claimed industry-leading performance, reliability, security and scalability. The Omnipower series provides standard IEC1107 and DLMS interfaces, wide temperature range, load profiling, built-in disconnect and prepayment, and tamper proof and magnetic immunity for residential single-phase and three-phase meters, and commercial and industrial CT meters.
“Like Kamstrup, Silver Spring believes it is important to take a holistic approach to the entire value chain in order to more rapidly deliver customised solutions,” said Hans Peter Kyk, general sales manager of Kamstrup. “Building on each of our own successes, we are excited to develop joint solutions with a company that has a track record like Silver Spring to meet the growing demands for intelligent energy in Europe, Asia, Australia, New Zealand and South America. This collaboration is part of our partner strategy of providing modular and interoperability from meters to analytics.”
Silver Spring has more than 24 million enabled devices delivered, and is working with smart energy and utilities providers and smart cities on five continents.
