Real solutions for real-world problems

Background
Bluecurrent has more than two million meters in Australia and New Zealand. In 2017, the Australian Energy Market Commission passed a rule called the 5-Minute Settlement, requiring smart meters to measure electricity consumption in 5-minute intervals, compared to the previous 30-minute requirements, with the change coming into effect in 2021. Bluecurrent needed to update its systems to comply with the new requirement, and it also wanted to be able to offer customers richer data services beyond billing to help them meet decarbonization goals. “We needed a solution that would let us flex as new requirements emerged,” says Anna Carrick, general manager of data services for Bluecurrent. “Within the energy market, there is rapid change coming from distributed generation, electrification, and smarter homes, so we need to have an architecture we can adapt for new use cases moving forward.”

VTS chose to develop a software-as-a-service solution using serverless technology from AWS to provide the scalability and resiliency that Bluecurrent needed. VTS and AWS formed a strategic alliance in 2020 to create a new solution. The result—called Diverge—went live after achieving accreditation against the new 5-Minute Settlement rules. “We passed accreditation with flying colors, in a fraction of the normal time,” says Ray Cheung, subject matter expert in metering data for Bluecurrent. As of January 2024, Bluecurrent is using Diverge for more than one million meters in Australia and New Zealand.

“The teams from VTS, AWS, and Bluecurrent worked together to achieve what the business needed to achieve—not only delivering a new system but working to enhance it and resolve the exceptions that come up in normal day-to-day work," says Anna Carrick, General Manager of Data Services, Bluecurrent.

Solution
Diverge is an entirely serverless energy data solution built on new and existing AWS services using infrastructure as code and a microservices architecture. The VTS and AWS teams collaborated along with subject matter experts from Bluecurrent and others in the industry to understand customer and market needs. “We had outstanding collaboration, not only through the strategic alliance with AWS but also between VTS and Bluecurrent,” says Patrick Cheffins, head of product for Diverge at VTS. “It wouldn’t have been possible without all of us working together.”

In order to ingest and store meter data at scale, Diverge uses services such as AWS Lambda, a serverless compute service, and Amazon DynamoDB, a serverless, NoSQL, fully managed database. It also uses new, purpose-built AWS services, including an energy data storage solution developed as part of the co-development effort. Diverge is processing six times the data ten times faster than Bluecurrent’s previous solution. It also has advanced features supporting efficient operations in Australia’s complex metering market, including an improved user interface and advanced tools for individual and bulk exception resolution.

The Diverge solution helps Bluecurrent store the data that it ingests on a new service developed by AWS as part of the strategic alliance specifically for storing energy data at scale and with high performance. Diverge then securely delivers the designated data to each of Bluecurrent’s customers, including to local distribution networks in order to provide visibility of power quality at the edge of the grid, to energy retailers for billing and enhanced customer service, and to electricity market operators for market settlement. Using Diverge, Bluecurrent is meeting stringent new Australian regulatory requirements and commitments to individual customers, delivering meter data hours earlier and more reliably.

“Now on AWS, Bluecurrent is delivering six times the data ten times faster,” says Dean Van Gerrevink, general manager of Diverge for VTS.

Bluecurrent is also more resilient because of the scalability of Diverge. Performance improvements mean the company can recover from any outage faster. “Because Diverge is cloud native and serverless, we can automatically scale to meet any increase in demand and then resume normal service automatically,” says Cheffins.

Summary
Diverge:

• Processes 6x data 10x faster to comfortably meet regulatory obligations and customer requirements
• Facilitates improved analytics in a secure environment
• Improves resilience and disaster recovery capabilities
• Provides a foundation to facilitate future innovation
