To Provide Services for the Development and Support of Changes to the MDM/R Data Mart

Affinity Systems is pleased to announce that it has been awarded the contract with Ontario’s Independent Electricity System Operator (IESO) for the provision of services for the development and support of changes to the MDM/R Data Mart and Web Services Facility, custom application development, and initiatives.

The MDM/R (Meter Data Management and Repository) was implemented by the IESO Smart Metering Entity, which provides a common platform for storing, processing and managing smart meter data for their 4.7 million customers in the Province of Ontario. The IESO has ongoing initiatives to ensure the MDM/R supports the increasing volume of data retrieval requests and the changes requested by the users of the MDM/R.

Affinity Systems played a key role in the design, development, and testing of the MDM/R Data Mart and Web Services Facility, making use of Logos, its high-performance, low-latency transaction middleware, combined with Kx Systems’ kdb+ time series database and q programming language. The solution is designed to ingest tens of millions of records a second, support hundreds of billions of records, and respond to time-series queries with millisecond latency.

“We are excited to work with the IESO in providing development services to enhance the smart metering platform,” says Leslie Goldsmith, Managing Director Affinity Systems. “Our big data expertise and significant background in time series analytics will support the IESO’s initiatives.”

“The IESO needed a skilled software development company with extensive experience in architecting and building large-scale and high performance systems, and the kdb+ time series database and q programming language,” said Przemek Tomczak, Director – Smart Metering at the IESO. “After conducting an open competitive procurement process, we are pleased to have Affinity Systems assist the IESO with the MDM/R Data Mart, custom applications and initiatives.”
