+ +High quality data plays a pivotal role in business success across various dimensions. Accurate and reliable data empowers business leaders to make well informed decisions and achieve operational efficiency, promoting growth and profitability. Data quality encompasses more than just accuracy it also includes completeness, consistency, and relevance. + + + +Maintaining consistent data quality becomes challenging without a robust data governance framework. Organizations often lack comprehensive data quality assessment procedures, so it’s crucial to regularly evaluate data quality using metrics and automated checks. Integrating data from various sources can introduce inconsistencies, but implementing data integration best practices ensures seamless data flow. Manual data entry is prone to errors, so automation reduces reliance on manual input. To measure data quality, define clear metrics such as accuracy and completeness, and track them consistently. Additionally, automate data cleansing routines (e.g., deduplication, validation) to streamline processes and reduce manual effort. Lastly, use of automation can help to identify incomplete or outdated records and regularly update data sources while retiring obsolete information. + +Maintaining data quality with time series data presents unique challenges. First, the high volume and velocity of incoming data makes real-time validation and processing difficult. Second, time series data often exhibits temporal dependencies, irregular sampling intervals, and missing values, requiring specialized handling. Lastly, dynamic data distribution due to seasonality, trends, or sudden events poses an ongoing challenge for adapting data quality checks. Ensuring data quality in time series streaming demands agility, adaptability and automation. + +## Data Quality Best Practices + +### Data Validation at Ingestion + +Implementing data validation checks when data enters a pipeline before any transformation can prevent issues from becoming lost and hard to track. It is possible to set this with automated scripts that can validate incoming data against predefined rules, for example, it is possible to check for duplication, outliers, missing values, inconsistent data types and much more. + +### Continuous Monitoring + +Monitoring of data quality can support the data validation and cleaning allowing the support team or developer to be notified of detected inconsistencies in the data. Early detection and alerting allow for quick action and prompt investigation which will prevent data quality degradation. + +### Data Cleansing and Preparation + +Automating data cleansing can be run as both a routine job and as a job triggered by failed data validation. Cleansing routines automatically correct or remove erroneous data, ensuring the dataset remains accurate and reliable. + +### Data Profiling + +Automated profiling tools can analyse data distributions, patterns, and correlations. By identifying these potential issues such as skewed distributions or duplicate records, businesses can proactively address them in their data validation and data cleansing processes. + +### Data Governance + +Data governance polices provide a clear framework to follow when ensuring data quality across a business. Managing access controls, data retention, and compliance, maintaining data quality and security. + +## RTDIP and Data Quality + +RTDIP now includes data quality scripts that support the end user in developing strong data quality pass gates for their datasets. The RTDIP component has been built using the open source tool Great Exceptions which is a Python-based open source library for validating, documenting, and profiling your data.

Energy companies, grid operators and industrial consumers rely on forecasts to optimise their operations. Over- or undercontracting can lead to significant financial losses, so precise forecasts are essential. Energy load prices and forecasts greatly influence the energy sector and the decisions made across multiple departments in energy companies. For example, medium to long-term energy forecasts are vital for planning and investing in new capacity, they guide decisions on new assets, transmission lines and distribution networks. Another example is risk mitigation, unstable electricity prices can be handled with accurate forecasting of the market, companies can develop bidding strategies, production schedules and consumption patterns to minimize risk and maximize profits. -Energy forecasting is foused on performance, i.e. how much over or under a forecast is and performance during extreme weather days.
