Sigma EI

To help you access and consolidate the wealth of energy related data held in Sigma, we have introduced 2 new default dashboards. This provides a starting point for you to explore your data in an insightful and meaningful way.

The Energy Management Dashboard provides a strategic summary level overview of your estate. This enables you delve into some of the following scenarios: year on year billing; usage by floor area; site performance; missing bills and their values; and much more.

The Site Analysis Dashboard allows you to interact with the data. In this dashboard you can change the commodity, site and time period and access metered consumption information including High Frequency periodic channel data. Here you will be able to browse usage and identify trends.

Other Sigma EI enhancements include:

  • Detail Bill Charge Data: more than 55 million pieces of data have been added to Sigma to provide a broad scope of individual utility bill charges. This provides the basis for more detailed utility charge analysis and simplifies data grouping for revenue assurance reporting
  • Extended High Frequency Data: the previous 14 months of high frequency consumption data from your periodic channels is now available. This extra data enables time period analysis of the previous year, month or week enabling you to identify trends or issues in your energy estate
  • Additional Bill Validation Information: a “Validation Message Detail” has been added providing additional details of validation failures to the core validation messages. This provides better understanding around bill query investigations
  • Additional Bill Related Data: an “Interim Actual Read Flag” has been added to help differentiate between bills that are entirely or partially based on actual consumption; or entirely on estimated consumption. Additionally, a “Bill Exported Date” flag has been added to help identify when bills were exported to support accounting processes
Bill Processing Improvements

Several enhancements have been made to improve the efficiency of bill management processing. These include:

  • Updates to the Data Input screen to display the “Supply Point for a Site”. This reduces the time taken to manually enter meter readings (particularly useful when receiving MPAN readings)
  • Inclusion of the invoice number and EDI batch number in the summary field of a query to help identify originating invoices when managing the query through its lifecycle
  • Added capability to re-validate bills that are associated to an account which will automatically repeat the validation checks for the selected bills which may be based on updated information since the bill was first loaded

Also included in release 12.1 are general bug fixes and an ongoing stream of non-functional changes to improve Sigma’s reliability and performance.
