Natural gas prices
Henry Hub benchmark natural gas prices came in at $3.01 per MMBtu (million British thermal units) for the week ended September 30, 2016. This compares to $3.11 per MMBtu for the previous week.
For the week ended September 30, natural gas futures prices also fell to $2.96 per MMBtu from $3.00 per MMBtu for the previous week.
Higher-than-expected natural gas inventory additions on a week-over-week basis had a negative impact on natural gas spot prices on October 6, 2016.
Why are these indicators important?
The US shale gas boom has led to a massive rise in natural gas production. This spurred a fall in natural gas prices and, as a result, natural gas became a strong competitor of coal, particularly in 2015. Cleaner, more competitive natural gas has eaten away at the market share of coal in electricity generation, which is a continuing trend.
As we discussed in the first part of this series, natural gas prices and coal’s market share in electricity generation are closely related. When natural gas prices rise, coal gains market share because it becomes more economical for utilities to use coal for power generation. On the other hand, a fall in natural gas prices generally leads to a drop in coal’s market share.
Impact on coal and utilities
For utilities (XLU) such as Dynegy (DYN) and NRG Energy (NRG), the impact depends on the level of regulation. For regulated utilities, the impact is generally negligible because the cost of fuel is part of the tariff calculations. On the other hand, unregulated electricity prices are falling due to weak fuel prices, putting pressure on unregulated power producers.
Next, let’s analyze the continued recovery we’ve recently seen in crude oil.
