The U.S. needs to deploy all available low- and zero-carbon resources "in the toolbox" to lower emissions and fight climate change, Entergy Corp. CEO Leo Denault and former U.S. Energy Secretary Ernest Moniz said during an Oct. 7 forum on New Orleans' energy future.
Bringing down greenhouse gas emissions requires "a combination of nuclear power, cleaner and more efficient gas-fired generation as well as the ever-increasing deployment of solar and other renewables," Denault said.
"Nuclear has to continue to be part of this," the CEO added. "Its cost structure, its reliability, its capacity factor all make sense in making sure we drive the right level of service to our customers at the right price while we do it sustainability."
Utilities and stakeholders also need to take a similar attitude toward natural gas, Denault said, adding that gas has allowed companies such as Entergy to move away from coal-fired generation to less carbon-intensive resources.
Moniz, who served as energy secretary from 2013 to 2017 during former President Barack Obama's administration, echoed those sentiments. Natural gas "has caused the revolution" toward the country's biggest carbon reductions, Moniz said. Gas with wind and solar remains a "complementary combination" until the industry achieves further innovation with batteries and storage to overcome more seasonality and weather conditions.
"Too often, the dialogue is going towards gas vs. renewables," Moniz said. "No, it's gas plus renewables ... there is no way around it. They have the intermittency that can be addressed, at least for now, through the integration with natural gas."
Denault and Moniz's remarks come as Entergy and its subsidiaries examine their generation fleet and sustainability efforts. During Entergy's July 31 earnings call, Denault announced that the company plans to add 7,000 MW to 8,000 MW of new renewable and gas-fired generation to its system from 2022 to 2030 to replace aging and less efficient power projects. In April, the company disclosed its new target to cut CO2 emissions intensity to half of 2000 levels by 2030.
Meanwhile, the New Orleans City Council is currently undergoing a rulemaking process to establish a renewable portfolio standard for Entergy subsidiary Entergy New Orleans LLC. In a June 3 letter to the city council, Entergy New Orleans proposed that the city should create a nonbinding goal of serving 70% of customers' energy needs with zero-carbon-emitting resources by 2030.
"We've been able to make those emission reductions by continuing to operate and maintain our nuclear plants," Denault said in his remarks.
Entergy Corp .首席执行长德诺( Leo Denault )和前美国能源部长莫尼兹( Ernest Moniz )10月7日在新奥尔良能源未来论坛上说，美国需要在“工具箱”中部署所有可用的低碳和零碳资源，以减少排放，抗击气候变化。
Denault 说，公用事业公司和利益相关者也需要对天然气采取类似的态度。他补充说，天然气使 Entergy 等公司能够从燃煤发电转向低碳资源。
2013年至2017年在前总统巴拉克•奥巴马( Barack Obama )执政期间担任能源部长的莫尼兹也表达了上述观点。莫尼兹说，天然气“已经引起了革命”，朝着该国最大的碳减排方向发展。风能和太阳能燃气仍然是一个“互补组合”，直到该行业实现电池和存储的进一步创新，以克服更多的季节性和天气状况。
德诺和莫尼兹发表上述言论之际， Entergy 及其子公司正在研究他们的发电车队和可持续性努力。在 Entergy 7月31日的盈利电话会议上， Denault 宣布，该公司计划在2022年至2030年期间向其系统中增加7000兆瓦至8000兆瓦的新可再生能源和燃气发电，以取代老化和效率较低的电力项目。今年4月，该公司公布了到2030年将二氧化碳排放强度降至2000标准的一半的新目标。
同时，新奥尔良城市委员会目前正在进行规则制定过程，以建立可再生投资组合标准的 Entergy 子公司新奥尔良有限责任公司。在6月3日给市议会的一封信中， Entergy New Oregon 建议该市制定一个非约束性的目标，即到2030年，以零碳排放资源满足70%的客户的能源需求。
“我们能够通过继续运营和维护我们的核电站来减少这些排放，” Denault 在他的讲话中说。
