Please note: This is a Sole Source Notification. Support and maintenance for eDNA software that is used to collect, store and display data for monitoring the nuclear power plants in Illinois. Following a competitive RFP process, IEMA selected eDNA software as the optimal solution for monitoring nuclear power plants. Recognizing the ongoing need to keep the software current and operational, IEMA anticipated the necessity of software support and maintenance. The agency is currently in the process of migrating from eDNA to AVEVA's PI System. Over the past decade, the maintenance and support contract with AVEVA has provided IEMA with 17 crucial software updates. Furthermore, IEMA has relied on AVEVA's support for bug fixes, new installations, and future development. Looking ahead, IEMA expects to require continued AVEVA support for tasks such as improving stalled calculation point identification, adapting to new data transmission protocols, and resolving data rendering issues in trend applications. Past resolutions to similar complex issues have involved direct modifications to AVEVA's proprietary software, highlighting the unique value of their ongoing support. IEMA has invested considerable time in customizing the current eDNA system, with the initial implementation taking four years to complete, encompassing customization, configuration, training, and parallel testing. The Agency is currently in the process of migrating from eDNA to AVEVA's PI System as part of a multi-year project. Pursuing a new system is not only cost-prohibitive, but the extended timeframe for procurement and implementation could compromise IEMA's ability to effectively monitor nuclear power plants, potentially jeopardizing public safety.
