Natural gas prices in Florida and at the US benchmark fell this week ahead of Hurricane Milton making landfall as a Category 4 storm on Florida's west coast, portending cooler weather and massive power outages that would erase demand for gas-fired electricity.
Gas and power utility Duke Energy Florida this week said that it was preparing for more than 1mn power outages. Hurricanes can also cut into gas and power demand by lowering temperatures and curbing cooling needs.
"Milton's intensity is expected to be unlike anything the Tampa Bay area has ever experienced," Duke said today.
Spot gas prices in zone 3 of the Florida Gas Transmission system on Tuesday fell to $2.44/mmBtu, down by 26pc from a week earlier and the lowest since 6 September. The closely watched Nymex gas price at the US benchmark Henry Hub in Louisiana on Tuesday settled at $2.733/mmBtu, down by 6pc from the week-earlier settlement and the lowest settlement price for the November contract since 20 September. Spot prices at the US benchmark on Tuesday fell to $2.395/mmBtu, down by 10pc from a week earlier and the lowest since 20 September.
Florida generated about 74pc of its electricity from natural gas in 2022, according to the US Energy Information Administration. The state's highly gas-reliant electric grid creates a stronger bond in the market for the two commodities.
Prices did not fall elsewhere in the eastern US this week, with weather forecasts on Tuesday and Wednesday revising expected US heating demand upward. Spot prices at Columbia Gas, Appalachia, a key indicator for the price of Marcellus gas supplies, on Tuesday rose to $1.60/mmBtu, up by 14pc from a week earlier and the highest since 25 September. Spot prices for the New York segment of Transco's zone 6 on Tuesday rose to $1.70/mmBtu, the highest since 18 September, while New England gas price indicator Algonquin Citygates rose to $2.085/mmBtu, the highest since 17 September. South-Atlantic gas price indicator Transco zone 5 also increased on Monday and Tuesday to $2.355/mmBtu.
