ChangeHeathcare produced Chelan PUD’s bills for 15 years. On Feb. 20, 2024, a ransomware gang, Black Cat, infiltrated ChangeHealthcare and locked them out of their systems. On Feb. 22, Chelan PUD quickly pulled together a basic bill in order to maintain the billing schedule for customers.
A few weeks after the event, when services still were not restored, Chelan PUD made the hard decision to move away from that vendor when we realized it may take additional weeks or months for Changehealthcare to recover.
With a new vendor on board, the PUD rebuilt the complex billing environment, having over 200 rate scenarios. We send about 2,000 billing statements a day and those statements compile information from multiple data systems.
New development endeavors like this typically take around 4 to 5 months. A cross-functional team at Chelan PUD, with our new vendor, has been working hard to return to full billing capabilities and were able to bring this project in on time.
We are grateful for your patience.
