Direct Answer
Spark spread trading takes positions on the difference between the price of electricity and the cost of the natural gas needed to generate it, adjusted for the plant's heat rate, which is the gross margin of a gas-fired power plant, by going long power futures and short gas futures when the spread is expected to widen, or the reverse when it is expected to narrow. It tends to work for traders with knowledge of regional power markets, where weather, outages and transmission constraints move the spread in ways that gas prices alone do not predict. Power price volatility is among the highest of any market; a spread can move more in a day than the expected gain for a season.

How Does Spark Spread Trading Work?
Spark spread trading takes positions on the difference between the price of electricity and the cost of the natural gas needed to generate it, adjusted for the plant's heat rate, which is the gross margin of a gas-fired power plant, by going long power futures and short gas futures when the spread is expected to widen, or the reverse when it is expected to narrow.
The rules:
- Compute the spark spread as the power price minus the gas price times the heat rate, in dollars per megawatt-hour
- Compare the spread to the marginal plant's break-even and to its seasonal history
- Trade the two legs in the ratio implied by the heat rate, typically around 7 to 8 million BTU per megawatt-hour
- Match delivery months and locations, since power and gas prices vary by hub and hour
Worked example. With power at 55 per megawatt-hour, gas at 3.50 per million BTU and a heat rate of 7.5, the spark spread is 28.75 per megawatt-hour, which is the margin a gas plant earns and the quantity a spark spread trade is long or short. The inputs are illustrative numbers, not market data.
When it tends to work. It tends to work for traders with knowledge of regional power markets, where weather, outages and transmission constraints move the spread in ways that gas prices alone do not predict.
When it fails. It fails when power prices spike or collapse on local events unrelated to gas, and the power leg's extreme volatility and illiquidity in some hubs make the hedge imperfect.
Main risk. Power price volatility is among the highest of any market; a spread can move more in a day than the expected gain for a season.
