25 years ago, Imperial Oil & TransAlta pioneered the first electronic billing (EBL) file process in Alberta. The electronic file (replacing thousands of individual paper invoices) was used as the source input data file processed by the invoice validation application known as the Electrical Power Supervision System (EPSS).  SoftLogic was contracted to support the development and maintenance of the system. As it remains today, the objectives of EPSS are focused on three core business needs:

1. Invoice Validation
   EPSS automated the process of validating the correctness of utility invoices against various filter thresholds.  Today, ISIS is the automated application developed by UTILITYnet that is used to validate all wires, settlement, and power pool invoice statement data.
2. Financial Link
   EPSS streamlined the journalizing of electrical power utility invoices to the company's general ledger. Bridges have been built to automate the posting to most financial systems.
3. Energy Management
   EPSS provided a number of energy management reports for use by both corporate and field personnel. During the last few years, the need for energy management has been expanded to include a variety of risk management analytical tools.

SoftLogic obtained the marketing rights to EPSS from Imperial Oil.

SoftLogic was reorganized and Utility Network & Partners Inc. (UTILITYnet) was launched, acquiring the intellectual property rights of EPSS.

As the electricity industry restructure the roles of the utilities changed and no longer was there a single company that provided a totally integrated generation, transmission, distribution and retailing  of electricity to customers.  The framework was set for customer choice and new Retailers and Self-Retailers entered the market.  UTILITYnet re-focused and built a data center designed to provide back office business services to companies wanting to take advantage new opportunities brought about by deregulation.

UTILITYnet developed and launched an integrated suite of retail, settlement and energy management Web Services to support the needs of it clients in the management and stewardship of their energy portfolios.  Billing agent services are being provided to wide cross section of clients in a variety of industries; Oil & Gas, Industrial & Manufacturing, Residential & Property Management, Provincial Educational Institutions & Municipalities, Hotels & Retail Stores and Agricultural & REAs.

Introduction of the UNETgrid marks a new era for delivery of energy management analytical services to the clients’ desktops.
