Generators and alternators and Hydropower dams

Energy flows from hydropower dams to generators and alternators; their prices have moved together.

Generators and alternators (energy) and Hydropower dams (energy): 2 relationships.

How they are linked

1. Energy flow

Physical flow · 100% of flow · Hydropower dams → Generators and alternators

Water turbines spin large generators inside the powerhouse.

• 100% of Hydropower dams's energy goes this way

2. Price link: main input

Cost and price · Moderate · Both ways

Each turbine drives a large generator, so generator makers supply a major part of dam equipment. The US generator index and turbine proxy move together over a year, with 12-month changes correlating at 0.52, a shared equipment cycle.

• 0.05 monthly change correlation
• 0.52 12-month change correlation
• 0.60 fitted elasticity
