先月20日の米国EIA（Energy Information Administration；エネルギー情報局）の発表によると、2016年の米国での電源構成で、天然ガス火力の発電設備容量（全設備容量の42％）と発電電力量（全発電電力量の34％）がいずれも石炭火力を超えて最大になったとの由。特に、2005年以降の天然ガスカ火力発電設備の増加は、天然ガスの石炭に対する価格競争力の向上が主因。
《原文より抜粋》
In 2016, natural gas-fired generators accounted for 42% of the operating electricity generating capacity in the United States. Natural gas provided 34% of total electricity generation in 2016, surpassing coal to become the leading generation source. The increase in natural gas generation since 2005 is primarily a result of the continued cost-competitiveness of natural gas relative to coal.
2017.4.20 EIA “Natural gas generators make up the largest share of overall U.S. generation capacity”

上記に関連して、先月17日のEIAの発表では、米国の石炭火力発電所の88％は1950〜1990年頃に竣工したもので、稼働年数は平均で39年となっている。これに対して、天然ガス火力は22年、石油火力は38年、原子力は37年、水力は64年、風力は7年、太陽光は3年。
《原文より抜粋》
Coal-fired electricity generators accounted for 25% of operating electricity generating capacity in the United States and generated about 30% of U.S. electricity in 2016. Most coal-fired capacity (88%) was built between 1950 and 1990, and the capacity-weighted average age of operating coal facilities is 39 years.
2017.4.17 EIA “Most coal plants in the United States were built before 1990”

また、今月17日のEIAの発表によると、米国の石油火力発電所の70％は1980年以前に竣工したもので、2016年末での発電設備容量は3％程度、2016年の発電電力量は1％未満であった。石油火力の比率が低いのにはコスト要因が大きいが、今後当面は完全にゼロとはならず、低水準で維持されていくだろう。これは、日本でも同様。
《原文より抜粋》
Roughly 70% of petroleum-fired electric generating capacity that still exists today was constructed prior to 1980. Utility-scale generators that reported petroleum as their primary fuel comprised only 3% of total electric generating capacity at the end of 2016 and produced less than 1% of total electricity generation during 2016.
