🧩 Installed Generation Capacity Chart Spec

Posted Oct 20, 2026

Chart type: Stacked bar chart

Purpose: Compare each company’s installed operating generation capacity (MW) broken down by fuel/source.

X-axis: Company

Y-axis: Installed capacity (MW)

Stacks: Gas, Coal, Nuclear, Hydro, Wind, Solar, Storage, Other

Note: Installed operating capacity only; excludes planned projects and announced pipeline additions.

Methodology: Installed capacity refers to the company’s operating generation assets currently in service, measured in MW. It excludes projects under construction, announced additions, and other planned capacity.
