NHA’s Operational Excellence (OpEx) program is a voluntary event reporting system that receives, distributes, archives, and catalogs Operational Excellence Information (OEI) and any resulting best practices and lessons learned.

Why is this important? As the industry contends with aging assets and an aging workforce, OpEx and the event reporting system will provide a trusted and reliable database of historical and current operational issues and serve as an educational and training resource for future personnel.
Who should register that will benefit from the OpEx tools? More than 180 organizations who are involved with:   • Safety (dam, employee, and public)   • Operations   • Maintenance   • Environmental Performance can help contribute and share vital data within your organization and as a whole collective. OpEx includes a number of tools that are easy to use:   • Event Reporting Creator   • Revision Tracking   • Notification of Events based on Criteria   • Searchable Event Database with Filtering   • Best Practice Library
Here are some organizations that are participating in OpEx:   • American Municipal Power   • Avista   • Bonneville Power Administration   • Chelan County Public Utility District   • Duke Energy   • Missouri River Energy Services   • Pacific Gas & Electric   • Seattle City Light   • Southern Company   • Tennessee Valley Authority
How does OpEx work and what are my benefits? NHA’s OpEx Event Reporting System module captures important events using a simple to use form. This form stores the event in a relational database that can support drafting, revision control, and multi-user contribution. Best of all, the reporting system is mobile friendly. The event report is drafted and submitted for approval. NHA coordinators will review, categorize, and redact any sensitive information. Once the event is approved for publication the event report can be searched based on criterias, and exported to various formats for viewing or distribution. You can even subscribe to certain categories to be notified via email of any future related events that are published into the reporting system. In addition to the Event Reporting System, NHA’s OpEx program has collected a clearinghouse of important knowledge from various sources and organizations. This is the Best Practice Library module, and as it continuously grows you can search to find relative information based on your needs and download important PDFs for viewing.
How easy is it to register? The OpEx program is for NHA members. However, you must still register separately to gain access to OpEx. The registration process is completed in two-steps to validate the user with their organization prior to gaining access to the event reporting system. You will be notified via email once your registration is accepted and complete.
