Data Validation for Power Generation

Applying Sigmafine in Power Generation

The Power industry, like so many other commodities, is experiencing declining prices, poorer quality resources, lower emissions emission limits, rising regulatory requirements and, now with agile customers who have no barrier to change supplier, thus forcing companies to remove any inefficiencies across the value chain from raw to material purchase through to supplied products to maintain competitive prices. To overcome the above challenges, this industry in embracing digital technology, including Sigmafine, to reduce losses and costs while improving asset utilization, integrity, streamlined business process and profitability.

Effective Business Process Digitalization

The Power & Utilities industry requires accurate and reliable production and equipment performance KPIS both which may be used as the basis for trade, product value/pricing, as well as in maintaining license to operate compliance. The task of effective digitization is an imperative for any company, to make efficient use of the its metered data to achieve higher levels of operational excellency. Implementing a solution that accurately accounts and reconciles all its internal measurements and its vendor transactions business data simultaneously at every significant time period can expose valuable information to engineers, operators, production planning optimization, loss estimation and management, to effectively operate the process to increase efficiencies and improved equipment utilization.

As this industry interfaces with the public, an important requirement of the digital transformation is the transparency and auditability of the entire business process, making this a fundamental requirement for the system to have the proper segregation of data depending on the user roles. This segregation prevents any unapproved changes to business rules, which must be aligned with auditing controls. Ultimately, this industry needs a system based on consistent information flows and business rules and thus independent of human bias.

An effective reconciliation process does not come without challenges, among these are: overwhelming amounts of information, varying unit of measure, lack of data consistency, unbalanced information from the flow rate measurement, and complexity to use information within the proper context. Sigmafine reduces the barrier to implement and manage information efficiently, and to validate and reconcile data based on business rules and conservation principles as specified by the company’s accounting rules or international standards. Beyond the features and functions that the platform gives to the end user, the Sigmafine solution enables a focal point to support the business accounting process that serves as the source of information for operational systems, performance monitoring program, as well as financial systems.

Supported applications

  • Reduce uncertainty in your KPIs
  • Apply first principles and concentration laws to achieve consistent data
  • Monitor and validate capacity and efficiencies
  • Estimate and monitor losses across the process unit’s distribution network

Comprehensive Business Accounting

Customers using Sigmafine have a solid foundation of an all-inclusive business accounting system, which provides validated, secured, and auditable information to the financial systems and accurate information to operation managers that can make use of this data to optimize the operations using a unified set of data. In addition, engineers and operators, using Sigmafine generated data, can compute process capacities, efficiencies or other KPIs with a higher degree of certainty.

The Sigmafine system is configured to perform mass, volume, energy balances for the whole utilities business which may include the distribution network. The Sigmafine Server with its powerful algorithms estimates the utility, in its correct unit of measure, to obey the fundamental conservation principle, throughout each processing unit, across the distribution and storage network. As a first step, Pimsoft uses the PI Asset Framework to create “process templates” of the different processes and related equipment (e.g., generator, filtration, heat exchanger, storage, etc.). After the initial setup, the solution requires the development of a connectivity model that represents the material flows of the facility and distribution network. During the last step, meters and analyzers are represented to receive information from the process data historian using out-of-the box connectivity.

Sigmafine advanced data reconciliation which minimizes the least square of errors on the “system/network” of measurements, now also estimates the site losses bringing them under supervision and control. Customers uses Sigmafine validated and balanced data:

  1. To support product distribution optimization (heat, steam, electricity, water, etc.);
  2. For hourly production balancing for near real-time target assessment
  3. To validate unit production efficiencies,
  4. For automatic validation and restoration of regulatory emission parameters
  5. For automatic data transfer to business systems and database.
  6. For auditability compliance

Simultaneous of the tightening of resources and regulatory requirements placed on the power and utilities industry, increased the demand of (low investment yet high ROI, fast payback, big data software analytics) a Sigmafine automatic data validation and reconciliation to provide process opportunities to go beyond measurement accuracies, be more proactive in quality metering and deliver early identification and warning of poor performing assets. It has been estimated, that the digital solution project, can have a payback period of less than 6 months.

Benefits

Improved data quality in the Power & Utilities Industry are primarily associated with:

  • Business financial accounting automation and validation
  • Leak/loss estimation and monitoring
  • Accurate monitoring of implemented production and environmental strategies

Business Impact

Sigmafine customers have achieved a standard accounting tool across all their sites and network, where the official information of all production figures and KPIs are safeguarded, available and configurable to the needs of operations, production planning, performance monitoring. Additionally, Sigmafine validated data may be sent automatically to any enterprise reporting system to facilitate seamless trade and billing transactions.

The Sigmafine solution facilitates higher level efficiencies because the assets are connected, and the Sigmafine data, is the “unified” data set which considers all the connected measurements and the respective tolerances which easily and track units, meters or sites performance.
