The price of natural gas is closely correlated to the cost of electricity due to the significant role that natural gas plays in power generation. Natural gas is a widely used fuel source for electricity generation in many countries worldwide.
How the price of natural gas affects the price of electricity:
Fuel Cost: Natural gas is one of the primary inputs in electricity generation. Power plants that use natural gas as a fuel source rely on a steady gas supply to produce electricity.
As the price of natural gas increases or decreases, it directly impacts the fuel cost for power generation. If the price of natural gas rises, it becomes more expensive for power plants to purchase and burn natural gas, leading to higher electricity prices.
Power Plant Dispatch: Natural gas power plants are often dispatched based on operating costs.
When natural gas prices are low, natural gas-fired power plants become more economically competitive than other fuel sources like coal or oil. In such cases, natural gas power plants are dispatched more frequently, increasing the overall electricity supply and potentially lowering electricity prices.
Conversely, when the price of natural gas rises, it becomes less economical to operate gas-fired power plants, and other sources may be dispatched more often, potentially increasing electricity prices.
Market Dynamics: Natural gas and electricity markets are interconnected. Changes in natural gas prices can influence the overall market dynamics and affect the cost of electricity.
For example, if natural gas prices spike due to supply disruptions or increased demand, it can ripple effect on electricity prices. Power suppliers may pass on the increased natural gas costs to consumers, resulting in higher electricity prices.
Infrastructure and Contracts: The infrastructure and contractual agreements within the energy sector also influence the correlation between natural gas and electricity prices. Many power plants have long-term contracts for natural gas supply, which can help stabilize electricity prices even when natural gas prices fluctuate.
Additionally, the availability and capacity of natural gas pipelines and storage facilities play a role in ensuring a reliable supply of natural gas, which can impact electricity prices.

It’s important to note that the correlation between natural gas and electricity prices can vary across regions and countries depending on factors such as energy market structure, regulatory policies, and the mix of energy sources used for electricity generation. Other factors like weather conditions, overall electricity demand, and the availability of alternative energy sources can also influence electricity prices.
Is natural gas cheaper than electricity?
- On an energy-equivalent basis, natural gas usually costs significantly less per unit of heat than electricity. For example, recent U.S. averages show natural gas around (1–1.50) dollars per therm (about (29.3) kWh of heat), versus electricity at (0.12–0.16) dollars per kWh, making electricity several times more expensive per unit of delivered heat.
- U.S. Department of Energy data finds that residential electricity costs are roughly 3.5 times higher than natural gas when compared on a per‑MMBtu basis. This translates into hundreds of dollars per year in savings for households using natural gas for heating versus all‑electric systems in most states.
- However, “is natural gas cheaper than electricity” and “natural gas cost vs electricity” are not one‑size‑fits‑all answers: local tariffs, fixed charges, appliance efficiency (for example, modern heat pumps vs older resistance heaters), and usage patterns can make certain electric solutions competitive or even cheaper in specific situations.
How does the price of natural gas affect electricity rates?
- In many U.S. markets, natural gas is the dominant fuel for power generation, especially for plants that set the marginal price in wholesale markets, so natural gas prices vs electricity prices are tightly linked.
- When natural gas prices rise, fuel costs for gas‑fired power plants increase, pushing up wholesale electricity prices and, over time, retail rates as those higher costs flow through supply contracts and utility rate structures.
- Conversely, when natural gas prices fall, gas units become more competitive compared with coal or oil, increasing gas‑fired generation, boosting supply, and often lowering wholesale electricity prices—though end‑user bills may still be shaped by non‑energy charges, delivery fees, riders, and taxes.
What causes natural gas prices to fluctuate?
- Natural gas prices fluctuate because of changing supply and demand conditions, including production levels, storage balances, and consumption for heating, power generation, and industrial use. rmi
- Weather is a major driver: cold winters and hot summers increase heating and cooling loads, raising demand and often pushing up gas prices, while mild seasons can depress demand and prices.
- Other factors include transportation and pipeline constraints, global LNG markets, regulatory changes, and producer behavior (for example, holding down production), all of which can make natural gas prices more volatile than electricity prices for end users.
Why do electricity prices track natural gas prices?
- In many competitive power markets, gas‑fired plants are dispatched based on their operating costs and frequently set the marginal price; as a result, electricity prices tend to track natural gas prices because gas is a primary fuel cost input.
- When natural gas prices spike due to supply disruptions or demand surges, the higher fuel cost ripples through electricity markets, as generators pass increased natural gas costs into power bids, raising wholesale and eventually retail electricity prices.
- While diversification into renewables and other resources can soften the link between natural gas and electricity prices, in regions where gas still dominates, “natural gas prices vs electricity” remain closely correlated, and understanding natural gas cost vs electricity is essential for forecasting power costs and planning efficiency strategies.
