## How they are linked

### 1. Price link: related index

*Cost and price · Moderate · Both ways*

The geothermal proxy is a closely related turbine index. Monthly moves correlate at 0.68 and yearly at 0.53, mainly because both cover overlapping turbine and generator products from the same factories, so this reflects shared costs rather than a geothermal market effect.

- **0.68** monthly change correlation
- **0.53** 12-month change correlation
- **0.65** fitted elasticity
