Is Your Fuel Mix the Perfect Cocktail for an Index Product?

In simple terms, a fuel mix is the combination of different energy sources used to generate electricity. These sources include coal, oil, natural gas, nuclear, hydropower, solar, wind and biofuels. Fuel mix varies by location, which is why it’s critical for commercial real estate owners to understand the composition of energy sources in their region. Knowing this can help determine which energy purchasing strategy could offer the greatest financial benefit for your company.

A Brief History of Fuel Mix

In the 19th century, energy sources were fairly homogenous, primarily made up of wood and charcoal. The 20th century saw a diversification of energy sources due to ever-growing demand.  This included the addition of hydropower and, later, nuclear energy. In recent decades, the push for sustainability and renewable energy has made solar and wind increasingly prominent in electricity generation.

How Does Fuel Mix Impact Energy Prices?

The fuel mix in a given state is largely determined by the energy sources that utilities choose to purchase, which is influenced by cost and availability. In Texas, for example, wind and solar make up a significant portion of the fuel mix due to low costs and abundant natural resources. Illinois, on the other hand, has the most nuclear reactors in the U.S., making nuclear energy a major part of its fuel mix.

Fuel mix is a key player in the world of energy prices because it affects the cost of electricity generation. No market relies on a single energy source, so the balance and ratio of different sources can significantly impact pricing. In Texas, the reliance on wind and solar results in greater volatility because generation depends heavily on weather conditions. In Illinois, where over half of electricity comes from nuclear energy, prices tend to be more stable and predictable.

The Role of Fuel Mix in Calculating Risk

Evaluating the fuel mix in specific markets can help gauge price volatility. In particularly volatile markets, locking into a fixed rate can serve as insurance against unpredictable price swings. In more stable markets, risk is lower, creating opportunities for commercial real estate owners to save money through index products.

Key Takeaway

A region's fuel mix, the blend of energy sources used to generate electricity, drives how much its prices swing. Markets that lean on wind and solar tend to see more price volatility, while markets with more nuclear or hydropower tend to be steadier. Understanding that risk profile is the first step in deciding whether a fixed-rate or index energy contract fits a business better.
