The Chelan County Public Utility District provides electric, water, wastewater public utility and telecommunications services in North-Central Washington, USA. The PUD also owns and operates two hydroelectric dams on the Columbia River with a total nameplate capacity just under 2,000 MW. It is nonprofit and customer-owned with an average residential electric rate of about 3 cents per kilowatt-hour.
The Chelan County PUD uses PI Asset Framework (AF) as a hub for operational data, forecasts, and digital twin modeling. The PI Analysis Server is leveraged for data transformations, notifications, and to initiate service requests in our asset management software. Internal and external web services, computers, and analytics servers connect to the PUD’s on-premises data using the PI Web API, and cyber security is maintained using Azure Active Directory. Finally, the PUD uses PI Vision for operational data reporting and dashboarding, and all of the data displayed there is accessed via PI AF.
Peter Vanney is a Data Analyst/Data Scientist/Statistician for the Chelan County Public Utility District in Wenatchee, Washington, USA. He is currently working on machine learning models to monitor stator temperatures, forecast Total Dissolved Gases in the river, and work towards condition-based maintenance. Peter’s favorite programming language is R, and he is relatively new to the utility space having joined the PUD in 2018 after working as a statistician in Texas. Peter’s BA in mathematics and MS in statistics give him a different perspective on computerized modeling that helps him bridge the gaps between IT, OT, Engineering, and the Senior Management Team.
