For over ten years Ontario, Canada has been a leader in the reduction of greenhouse gas emissions by closing coal-fired plants, diversifying its energy supply mix, promoting conservation, implementing time-of-use rates for electricity and by installing smart meters across the province.

The data from smart meters is processed by a government agency called the Independent Electricity System Operator (IESO) that manages Ontario’s bulk-power system. The IESO’s responsibilities include ensuring that there is enough power to meet the province’s energy needs in real time while also planning and securing energy for the future. The Smart Metering Entity within the IESO, operates the provincial smart meter data processing service (the MDM/R) for 67 distribution system operators and over 4 million customers.

The volume of data generated by the province’s smart meters exceeds 250 billion meter reads, and grows by 100 million reads per day. The administrator of this data is required to process and provide billing quality data to the utilities in the province in a timely manner and has set up a meter data management system (MDM/R) to do so.

However, the existing transaction and relational database system within the MDM/R was not originally designed to handle the increasing requirements of the fast growing data set and its users. That’s where Kx came in with its high-performance database system kdb+, and the suite of powerful data access and analytics tools built on top of it. The IESO chose Kx after evaluating a number of other technologies, and performing over 25 tests on five years of simulated data from 5 million smart meters. They found that kdb+ delivered very high levels of performance at the lowest total cost of ownership.

The IESO implemented a Data Mart using Kx technology to support the current volumes of data access requests and anticipated growth with 24x7x365 availability, as well as current and future demands for advanced analytics in Ontario’s energy sector. The Data Mart delivers low-latency simultaneous data ingestion, transformation, data retrieval requests, and is synchronized in near real-time with the MDM/R system. For example, with kdb+ the IESO is able to aggregate an entire year of data for all meters in a few minutes, which supports analysis of load profiles, consumption behavior and different rate models.

Ontario is taking the lead again, in adopting advanced tools for retrieval and analysis of the province’s smart meter data using Kx technology. To read more about the IESO use case, click here.

Kx recently became an official team supplier to Aston Martin Red Bull Racing who is using Kx technology to handle mission-critical aerodynamic data. Below is an article published by Aston Martin Red Bull Racing on 11 January 2018 which explains the importance of this aero data, and working with Kx technology, for improving car performance for the F1 Team. It outlines how Kx’s in-memory, time series database software, capable of handling millions of events and measurements every second, provides a platform for analysing data on the RB14 and its successors.

Kx Insights: IIoT for Predictive Maintenance and Big Data

9 Jan 2018 | , , , , , ,

IIoT for predictive maintenance enables more extensive monitoring of equipment and processes at a much lower cost than traditional methods and delivers actionable warnings to prevent or minimize the consequences of an impending failure. Where IIoT for predictive maintenance is deployed in a well-designed program using Reliability Centered Maintenance (RCM) it will reduce surprise outages, lost production, extensive repairs, secondary damage and increase safety.

MiFID II, The Day After

4 Jan 2018 | , , , , ,

Don’t pop the champagne yet for the launch of Europe’s Markets in Financial Instruments Directive (MiFID II). While January 3rd was the go-live date, and the industry is thought to be 80% compliant, there are major outstanding issues to contend with in 2018. Yesterday was simply a milestone marking the turn to the home stretch.
Although MiFID II has been in the works for many years, its Level II and Level III guidance was still being finished in the second half of 2017, which has meant an uncomfortable level of ambiguity for those who must implement MiFID II.
