As industry leaders serving the needs of every single deregulated energy market in the US, we have comprehensive insights into precisely what our clients require in a radically changing operating environment.

Efficiency is absolutely essential to success in the deregulated energy marketplace. The challenges of deregulation – such as constantly changing rules and regulations and the required separation of grid and energy – along with increased market competition, has placed the focus for organizations firmly on operational efficiency to survive and thrive. Deregulation has also brought with it a dramatic rise in the flow of business transactions between Utilities and Energy Suppliers through Electronic Data Interchange (EDI).

To overcome these challenges and turn the ever-changing environment into opportunities for sustainable market success, energy companies require automated internal and external processes that operate in a reliable, cost-effective and customer-friendly way.

With EC Infosystems’ value-adding technologies and the tight integration between our UtiliBill™ Billing/CIS and EDI platforms, our clients stay ahead of the changes and operate efficiently. From our advanced real-time tools and reporting to our proactive transaction tracking and end-to-end process management, our clients reap significant benefits at a lower cost to serve for both Utilities and Energy Suppliers alike.

Icons of platforms we support: Windows Linux and MacOS X
