The IRP is a long-term planning study that evaluates how NorthWestern Energy can meet Montana customers' electricity needs over the next 20 years under a variety of future scenarios, while balancing reliability, affordability, and risk. It provides a transparent analysis of potential scenarios to guide future decisions.

What the IRP examines:

• Forecasts of future customer demand (including population growth, energy efficiency, and net metering)
• Existing generation and transmission resources
• Potential capacity options
• Cost, reliability, and risk trade-offs across multiple future scenarios

Goal: Identify the most cost-effective capacity to meet reliability needs while managing risk and cost for Montana customers.

The IRP is not a construction plan or a final decision document.

The meeting will include a 20-minute presentation followed by time for public comments on the draft IRP.
