How to Hedge the Risk of Reduced Snowpack for Hydropower

A new index insurance contract – a financial product innovation seeking to cope with climatic variability – could help hydropower operators to manage climate risks.

There has been an increasing number of papers in Water Resources Research on financial instruments to manage climatic variability. Hamilton et al. [2020] introduce a new index insurance instrument to help hydropower producers who depend on snow melt to cope with the risks of variable snowpack. This is a critical risk in snow-dominated regions such as California, where a significant fraction of the streamflow every year comes from a small number of large winter storms that do not always occur.

The authors use analysis of the relationship between snowpack and revenues to build a risk model. They examine the financial structure of a hydropower company and the possible attitudes of risk managers to debt and revenue risk. This can limit the extent to which a loss of revenue caused by drought reduces the long-term financial viability of a utility, improving outcomes for the public.
