Billing & Energy Accounting

MCG’s Energy Accounting System (EAS) allows for the tracking and management of a variety of time series data types. MCG’s EAS Pyramid enables the energy accountant to define multiple levels of rollup accounts for visualizing various calculations (load calculations, imbalance calculations, contract calculations, etc.) through drill-down functionality.  The system will track multiple different data sources for a single meter, which can be ranked in order to generate an official profile based on the best available source of data for that interval. Tolerance checking allows the system to flag suspect values while still accepting the data from the source. Multiple levels of multipliers can be used to flip signs on incoming data, or to apply loss factors. The system also supports multiple types of rounding methods such as round, round up, round down, truncate, or truncate and carry, which can be set on a meter by meter basis.
