Last Chance Hydroelectric Power Plant, Idaho | PacifiCorp

Last Chance is a hydroelectric power plant located in Idaho, United States, with an operational capacity of 1.7 MW. Owned by PacifiCorp, the facility is part of the company's renewable energy portfolio, supplying clean electricity to the region. As a small-scale hydro plant, it plays a role in diversifying the local energy mix. The plant operates under the regulatory framework of the Federal Energy Regulatory Commission (FERC) and must comply with environmental standards such as the Clean Water Act. Hydroelectric facilities like Last Chance typically use run-of-river or impoundment technology, with low emissions compared to fossil fuel plants. The 1.7 MW capacity places it in the small-scale category for hydropower. Last Chance contributes to the local grid by providing baseload or peaking power depending on water availability. Its operation supports PacifiCorp's renewable energy goals and reduces reliance on fossil fuels. The plant's location in Idaho benefits from the region's abundant water resources, ensuring consistent generation.

Hydroelectric power generation has a low carbon footprint but can affect local aquatic ecosystems. Last Chance's small scale minimizes habitat disruption compared to larger dams. The plant's operation must balance power generation with downstream water flow requirements to protect fish and other wildlife. Idaho's mountainous terrain and snowmelt-driven hydrology provide a reliable water source, but seasonal variations can impact output.
