EIA’s Electric Power Monthly – January 2019 Edition with data for November 2018
The EIA released the latest edition of their Electric Power Monthly on January 25th, with data for November 2018. The table above shows the percentage contribution of the main fuel sources to two decimal places for the last two months and the year 2018 to date.
In November, the absolute amount of electricity generated declined sightly as mild fall temperatures gave way to colder winter temperatures with demand for air conditioning giving way to demand for heating. Coal and Natural Gas between them, fueled 61.99% of US electricity generation in November, with the contributions from Nuclear and Conventional Hydroelectric edging up. The contribution from Natural Gas was down at 33.18%, from 38.11% in October, with the amount generated falling from 124,027 GWh to 106,804 GWh. Generation fueled by coal increased from 87,452 GWh to 92,738 GWh resulting in the percentage contribution rising from 26.87% to 28.81%. The amount of electricity generated by Nuclear plants increased from 59,397 GWh to 63,948 GWh with the resulting contribution actually rising from 18.25% to 19.87% in November. The amount generated by Conventional Hydroelectric increased from 18,779 GWh in October to 22,174 GWh in November with resulting contribution increasing to 6.89% as opposed to 5.77% in October. The amount generated by Wind decreased from 19,507 GWh to 17,991 GWh with the resulting contribution falling from 5.99% to 5.59% in November. The estimated total solar output fell from 7,625 GWh to 5,859 GWh with the resulting contribution falling from 2.34% to 1.82%. The contribution of zero carbon or carbon neutral sources rose from 34.10% in October to 36.97% in November.
