US Power Generation Fell for the Fourth Straight Week



US power generation

According to data released by the EEI (Edison Electric Institute), the United States generated 83,468 gigawatt hours of electricity during the week ended August 28. That’s 4.7% less than the 87,622 gigawatt hours the country generated during the week ended August 21.

But, as we saw in the previous part of this series, natural gas demand from the power sector increased in the week ending September 2. So it’s likely that we could see an increase in power generation for the week ended September 4. Keep a look out for our report next week. On a year-over-year basis, the United States generated ~2.8% less power in the week ended August 28 compared to the corresponding week in 2014.

Natural gas versus coal

Since electricity generation companies depend mainly on coal or natural gas to generate electricity, decreased electricity generation is likely to reduce demand for coal and natural gas. This would be negative for both coal and natural gas producers.

However, given that natural gas is a cleaner fuel and that it’s abundant, it’s expected to take market share away from coal in the long term. This would be bullish for natural gas prices and natural gas producers such as Devon Energy (DVN), Southwestern Energy (SWN), Range Resources (RRC), and QEP Resources (QEP). These companies make up ~3% of the Vanguard Energy ETF (VDE).

Short-term trends

According to the EIA (U.S. Energy Information Administration), a total of ~889 Bcf (billion cubic feet), or ~29.6 Bcf per day, of natural gas was consumed for the purpose of electrical power generation in June, the latest month for which data is available from the EIA. It’s interesting to note that of the ~1,927 Bcf delivered to end users in June, electricity generation accounted for the most at ~46%.

Also, according to the EIA, coal consumption in 2015 is expected to fall 7% fueled by lower natural gas prices and increased electricity generation based on renewable energy. The EIA forecasts that the share of coal-fired electricity in terms of overall power generation will average 35.6% in 2015, down from 38.7% in 2014. In contrast, natural gas should account for an average 31.2% of power generation this year, up from 27.4% last year.
