Using detailed 5-minute electricity generation data, we examine the impact of wind intermittency on carbon dioxide (CO2) emissions savings from wind energy in the Southwest Power Pool from 2012-2014. Parametric and semi-parametric analysis confirms concerns that intra-hour wind intermittency reduces CO2 emissions savings from wind in the top decile of wind intermittency, emission savings are reduced by nearly 10 percent. However, the average wind intermittency effect on emission savings is modest, on the order of 4 percent, with reductions in savings on the order of 6.5 percent when accounting for dynamic effects. Evidence suggests the intermittency effect is likely to remain modest in the near-term. JEL Codes: L94, Q42, Q53, Q58

风能的间歇性和二氧化碳减排

使用详细的 5 分钟发电数据，我们研究了 2012 年至 2014 年间风电间歇性对西南电力池中风能二氧化碳 (CO2) 减排量的影响。参数和半参数分析证实，在风力间歇的最高十分位数中，小时内风力间歇会减少风产生的二氧化碳排放量，减排量减少了近 10%。然而，风能间歇性对减排的平均影响不大，约为 4%，考虑到动态影响时，减排量约为 6.5%。有证据表明，间歇性效应在短期内可能会保持温和。JEL 代码：L94、Q42、Q53、Q58
