    When Angel McCoy was in third grade, she fell in love with the sky.
    “I became obsessed with weather, space, and earth science,” recalled the National Renewable Energy Laboratory (NREL) senior offshore wind regulatory specialist. “I knew I was either going to be a meteorologist or an astronaut when I grew up.”
    McCoy chose meteorology and started her career as a meteorologist at the National Weather Service’s Climate Prediction Center, where she worked for four years before taking a job at the U.S. Department of the Interior’s Bureau of Ocean Energy Management (BOEM). That role was not what she expected, but it put her on the path that led to her current role at NREL.
    “When I worked at the National Weather Service, I wrote code for things like rainfall modeling, so when I took the job at BOEM, I thought I’d be writing code for wind and solar models,” McCoy said. “It turned out my new job was a regulatory position, which meant I needed to know environmental law. That was a shocking realization, but I saw the need for sound science to inform regulations, so I made a commitment to stick it out for five years. I fell in love with the work and stayed for 12 years.”
    Today, McCoy works in NREL’s offshore wind energy program, where she leads engagement with BOEM and the Bureau of Safety and Environmental Enforcement (BSEE) to support the regulatory process for offshore wind energy in the United States. We caught up with McCoy to learn how she made her way to her current role and how she invests in the next generation of scientists and clean energy leaders.
    Meteorologist to offshore wind regulatory specialist is a slightly surprising career trajectory! Tell me more about the path that led you here.
    I’ve admired NREL’s work for many years. When I worked at BOEM, I was the subject-matter expert and liaison to NREL. I worked closely with NREL researchers and crossed paths with them for many years at workshops and conferences, and there were times when, while sitting in my regulator seat at BOEM, I would think, “I should be over there with the experts at NREL.” It became a secret dream of mine to join NREL, so when this opportunity became available, I had to go after it.
    Now that you are on the research side of offshore wind energy regulation, what do you like about working at NREL?
    It’s great to have an impact on the industry from the research side, to lead research teams, and mentor junior staff. I love being on a team of people who are the best of the best. We all have an area of expertise, and we all value one another’s expertise. We make room for everyone to contribute, and we respect everyone for the value they bring to the team.
    Another good thing about NREL is that I have come full circle in many ways. I’ve known several of my current colleagues for years now, having met them at wind and renewable energy workshops or conferences over the years, and now we’re colleagues. I feel that I’ve found my place here. After I left BOEM, I did a short stint as a consultant to offshore wind energy developers. It was good to see that side, but it didn’t feel like the right fit for me. Now that I’m at NREL, I feel that my work makes more of a lasting, positive impact, which makes it more rewarding.
    And what is your role here at NREL? How would you explain your work in layman’s terms—or, say, to a fifth grader?
    Actually, I explain my work to fifth graders all the time! I go to school science fairs and career days, and I run an earth science camp. When I speak to students, I tell them that it’s possible to create electricity from the wind, and then I ask them if they’ve ever seen wind turbines on land before. Most kids will say they have, or they’ve at least seen pictures of them. From there, I say, “We can also build wind turbines out in the ocean where there’s more wind. My job is to help build offshore wind turbines safely and in a way that minimally impacts, for example, people and animals who live by the ocean or people who use the ocean for fishing.”
    You also run a science camp? Tell me more!
    For many years, I volunteered at schools, doing hands-on earth science workshops and presenting at assemblies and science fairs. Eventually, the teachers, counselors, and principals said, “You know, schools have budgets to pay for stuff like this. You don’t have to do it for free.” Now, I run a science camp called Discover Earth Camp. It’s my passion project. Part of the motivation comes from my own childhood fascination with the sky, so my goal for Discover Earth Camp is to expose other children to earth science and the natural world, because if I catch them as children, then I’ve got them for life.
    Running a science camp for kids is also having a big impact—on the next generation. You mentioned you mentor junior staff at NREL, too. What advice do you have for young people, college students, or those who are early in their careers?
    Don’t limit yourself! When you’re young or just starting out, you may have a strong idea of what you want to be when you grow up or you may have one area where you’re especially knowledgeable, but I found my path because I was open to more than what I was initially seeking. Allow yourself some wiggle room to explore other opportunities. You may stumble across something else that interests you along the way. Then, you’ve picked up expertise in something that you never expected.
    Also, look back and celebrate how far you’ve come. Don’t forget those who have mentored you or guided you with even a simple word of encouragement along the way. I had a milestone birthday celebration in January, and I have been very reflective of all the people who I have crossed paths with and who helped keep me going or helped propel me to where I am now—some of whom are now my colleagues at NREL.
    It is great that you are inspiring the next generation. Let’s assume you are still explaining your work to one of the fifth graders at your camp. Can you explain why is your work important? What problems does your work attempt to solve?
    With fifth graders, first they need to understand why wind energy is important. I tell them, “The traditional ways that we get electricity to our homes can hurt the environment, and so we have other resources, like the sun and the wind, that we can use to get cleaner forms of energy to our homes. This way, we can keep our planet healthy for future generations.”
    Getting more into the regulatory aspects of offshore wind energy, I would say, “Whenever the government must make a decision, like whether to approve a new offshore wind energy project, sometimes they don’t have all the information they need right in front of them. That’s when they turn to NREL researchers and say, for example, ‘We need to better understand the available wind resource out here in the Pacific,’ or, ‘We need to understand the technological constraints of transmission or anchoring to the sea floor.’ Basically, I support the research that helps people in government make decisions and develop regulations around offshore wind energy.”
    It is clear that your work is very important for the advancement of U.S. offshore wind energy. What have you accomplished in your career that you are especially proud of?
    In her previous role as BOEM’s liaison to NREL, Angel McCoy worked closely with NREL researchers to develop offshore wind energy regulations. Now that she is at NREL, she supports the research that informs those regulations. Photo from Angel McCoy, NREL I’ve worked in offshore wind energy for 14 years now, and since the U.S. offshore wind energy industry is so new, I’m almost like an industry veteran. I’m proud to see the influence I’ve had on this industry.
    For example, when I worked at BOEM, I wrote the guidelines for lighting and marking U.S. offshore wind facilities. There is no regulatory authority for how we should light, paint, and mark these structures out in the ocean. I developed guidelines that ensure safe air and sea navigation within and around facilities while also ensuring that the design is safe for birds and marine animals. Now, the entire U.S. offshore wind industry refers to them.
    Now that we have reflected on your past, let’s talk dreams. What are your hopes for the future of wind energy and its workforce?
    We’ve been working at U.S. offshore wind energy development for so long now, I just can’t wait to see a full-scale commercial facility operating in federal waters—and that’s right around the corner. I feel like I’m going to shed a tear when that day comes.
    Also, I know the administration has the goal of 30 gigawatts of operational offshore wind by 2030, but even if we could have 30 gigawatts approved and secured in the pipeline, that would be awesome. If we can reach those short-term milestones, it will be great for the industry.
    Finally, I look forward to the accomplishments of those coming up behind me. I was just at the American Meteorological Society’s annual meeting last week participating in the energy track, and I was talking to a lot of college students and other young people, and they were picking my brain, asking questions about the future of offshore wind. It was exciting to say I was on the front lines of making U.S. offshore wind energy a reality, but now I can look to the next generation to run a successful, functioning industry. The way I see it, my role is to make it happen now. It’s the next generation’s role to keep it going.

    • 2020年9月17日,由江苏可再生能源行业协会联合中国长江经济带可再生能源装备制造产业联盟、江苏省新型电力(新能源)装备集群共同主办“第十三届中国(江苏)国际风电产业发展高峰论坛”在江苏南京盛大召开。北极星风力发电网、北极星电力APP对会议进行全程直播。 去年讲进展情况,去年是建国70周年,另外也是想做小小的总结。我做风电25年,江苏风电15年。我2003年、2004、2005年我都是主要的负责人,专业的负责人。因为2005年实际上处于风电出来之后,我们就比较敏感捕捉到觉得江苏海上风电是我们一个更加广阔的天地,所以2005年12月份,当时分管院长带着我们团队就去英国、丹麦做第一次海上风电考察,从那个时候开始我的主要精力实际上转向做海上风电工作。 海上风电发展到去年年底,总共500多万接近600万装机容量江苏占70%多,这个比例还是非常高。我所了解到6月底,我们江苏海上风电总的装机容量已经达到464万,今年年底过500万甚至于更高已经不是什么问题。全国的十三五规划650万总的容量已经提前完成,基本上今年6月份全部海上风电容量超过650万。今年是800多万还是1000万还是悬念,很有可能今年年底达到1000万,今年年底有可能达到世界第二,有可能超过德国水平,德国去年很少,今年海上装机也不大,所以不进则退。 第二个我们的成本快速下降,大家知道东海大桥离岸距离只有十多公里,那个项目在投产竣工结算23000块钱一个千瓦,这样的项目后来我们到了2012、2013年做的时候,项目已经降到14000多,这块努力上面。到了2018年的时候,一些项目十多公里,十来米水深项目已经做到15000左右,最近随着增个造价在反弹。2022年,我们更多拿2017、2018年数据去,在这个基础上面考虑我们的技术进步发展推进进行测算,总体上面来说江苏还是处于全国风电单位千瓦造价是属于最低水平,但是单位电镀成本还是福建风资源特别好,造价成本还合理的一些区域里面,他的成本会更低一些。 通过几年的努力,我们的整个产业的技术体系不断完善,今天刚才我们前面有教授专门讲了,江苏的产业链集群,这个也是借助我们江苏可再生能源协会帮助统计,2018年的时候就是跟风电相关联,营业收入超过2亿元有298家,目前大致来说江苏目前的风电产业,基本上都是在1000多万,前段时间南通和盐城,每个政府都说在市里面风电产业有2000万,我没有统计没有发言权,我想可能这个量级已经到2000万这样的量级。 随着风电快速的增长,包括欧洲国家一些先进的国家,英国、德国这些包括丹麦、比利时、荷兰这些先进国家,他们在海上风电成本的确下降非常快,2019年他们的新招标出来价格基本上3毛5分钱,这3毛5分钱不含原海登陆那部分费用是没有包含在里面,所以这部分费用按照目前110万千瓦并网项目,基本上单位千瓦4000多块钱,折算过来电价1毛5分钱,加上去价格在5毛钱左右,所以有误导欧洲人海上风电招标电价已经多少,这个招标电价实际上建成又是三到五年期,并不是招出来价格就是真正实施价格,而是几年之后的价格,这个给大家做一个解释。 总体来说的话,远海风电特别是2022年以后,我们城市规划一些前提工作的咨询机构要有共识,2022年到2025年这段时间,可能近海空间开发,以近海为主,远海做一些工作。这里面指的我个人意见,近海项目还是一些十三五期间由于种种原因,已经纳入十三五规划,由于种种原因没有核准,甚至已经核准由于种种原因没有开工,这样的项目就是离水十多米,远的三十多米,按照2018年的成本基本上在一万五到一万六,这样的项目成本比较低的存量项目先在2022、2023年先去建设。但是这样的项目,第一个实际上总量不多,第二个这样的项目跟其他矛盾相对来说要说一些,新的规划更多引导做双30、双40,甚至于要30、40米水深,距离几十公里,70、80公里,甚至100多公里发展,这样对于技术储备有过程,我们提出来远海要做一些示范。远海示范实际上里面有一个潜台词,示范是要政府一个给予政策支持,今后招投标定价是有差别,不能像现在一刀切,远海示范可能遥遥无期的。 从发展和展望来说,第一个今天上午两位北京来的专家给大家更多一些信心,这个坚定不移发展可再生能源这是国家的意志,可以说应该是毫不动摇要往这个方向来做。但是在清洁可再生能源多发展光伏,还是多发展陆上风电,还是海上风电,首先资源量比较大,另外它能够降低成本和空间谁更大一些,这样我们事实上后续发展空间也会更大一些,这块我们认为至少作为江苏的特点来说,我们要通过海上风电大规模的开发,从目前2700、2800水平要求希望快速提升到3300,有可能到2025年争取3500、3600的水平,这个我想一直跟我们组机场,跟叶片厂家也在讲往这个方向去努力。 另外一个,我们的政府也已经在行动,今年上半年和下半年南通市和盐城市,都有比较大的动作。整个规模比我们今天会议规模还要大一些,基本上600到800人的规模,就是要着力推动海上风电的规模化和装备制造业的发展。像盐城专门为海上风电发展发表了白皮书,目前海上风电从地级市来说已经是全国第一到291.5万千瓦这样的容量,第二个也提出来能源技术革命来助推产业升级,各个部门都在着力按照这个要求推进;另外特别提到,健全完善产业链条,这块上面沿海两个市对这个推进力度很大。 所以,江苏省我们已经建成了第一个沿海千万千瓦风电基础,我个人预测为2025年,就是下一个十四五末的时候,可能还会略微提前一点,这个包含600多万沿海,陆地、滩涂的风电,真正的海上风电预测1400到1500万到2025年江苏,只是完全是我个人的愿景或者个人的推算。 今天一个主题,我们是补贴退坡背景下如何实现产业链升级,通过加大转能,通过主机配套产业链的成本,能够在2018年基础上降1000块钱以上,包括线路优化,包括基础的设计优化,施工装备能力提升等等这方面,通过共同的努力,我们就是通过发电量提升10%,我们成本降20%到30%,通过这样联合作用把我们到2022年电价,希望在0.5到0.55的水平,我们也写了相关的分析报告给政府的主管部门进行研究。 另外一个就是说,我刚才讲这是联合驱动,通过主机设备技术进步,通过优化设计,通过海上风电智慧化管理来降低成本,然后通过往深远海方向发展,来拓展我们的资源空间和发展空间。具体的我们一些细的地方,我们讲的比方说从设计院角度来说,跟制造企业、主机企业一起通过模型和雷达,一系列工作把选址进一步提高,争取通过这样基本上不太增加成本一个下面,增加2%到3%的发电量。7兆瓦以上采用限电66千伏,好处可以增加单位千瓦,每个维度我们可以把节电容量从现在30000提高到50000,另外能够降低输电线路的损耗。还有如果有可能的话,目前研究能不能通过66直接登入到柔性里面,直接转换成柔性支流,这样对于一些100万不到的项目,我觉得也是可以做比较研究工作。 另外,上周到电缆企业里面做了调研,有没有比方铝芯替代铜芯、或者绝缘材料国产化,对于海揽成品的造价成本有12%到18%的下降空间,电缆建好通过三天左右维护,总体来讲开足马力搞供应。另外,专门花一个亿投资专门制造勘探船,使的这么深的地方我们也可以CPT精确的勘探手段;另外水深往深走了,之前的可能不是最优的手段,最近也在制定新的设计。我们也提出来施工装备产业链提升,我们也呼吁施工企业在这方面加大。综合性强的勘探船在10亿左右,以后就是资本竞争的态势。 另外一个就是下午专家讲到海上风电智慧化,我刚才讲到一些产业链升级,大部分都已经讲到,第一个首先主机大型化是必然趋势,我想到2022年可能6兆瓦以下的风机,除了很近很浅,包括江苏风资源平均比较小,或者基本没有台风区域用6兆瓦,后面基本上想7兆瓦、8兆瓦、10兆瓦,可能是十四五前面一个主流的机型,10兆瓦可能稍微往后靠一点。 另外,刚才讲到多种机型,今天还讲到超过70公里距离上百万的装机规模,我们目前最佳选择要并网,110万这样一个在建里面400千伏最高正在建设当中,目前组建推进在计划,目前计划明年6月份现场安装好,争取调试成功。另外,就是综合利用,这个时间关系不多是了。我们刚才也讲,目前为了十四五更远的发展和更大的空间,所以我们做更多的超前研究,主要就是往深远发展,作为设计院一是对于深远海我们要PK原油近海很多的规范不一定适用,原来很多都是近海港口和一些油气平台,借用美国的标准,经过中国的风电已经有1000多万的装机,这个时候或者说编制出来的深远海标准,或者说把我们现有的进行升级,这块我们都在做相应的技术储备的工作。 谢谢大家。
  • 《海上风电“省补”来了!》

    • “省补”的出台势必会对本省的海上风电发展有正向的刺激作用,尤其是广东和山东出台的“省补”都按项目容量进行一次性补贴,更可以直接帮助项目降低成本。 近日,浙江省舟山市人民政府发布《2022年风电、光伏项目开发建设有关事项的通知》(以下简称《通知》),给予海上风电项目一定的省级财政补贴,2022年和2023年全省享受海上风电省级补贴标准分别为0.03元/千瓦时和0.015元/千瓦时。浙江由此成为继广东、山东后,第三个明确海上风电省级补贴支持政策的省份。省级补贴的陆续出台一时提振了海上风电市场,业界普遍认为,“省补”将有力推动海上风电向全面平价过渡。 “先建先得”,逐年退坡 去年11月,浙江省首次透露将为海上风电提供金融、财政支持,但并未公布补贴标准细则,时至目前,浙江省成为了全国第三个为海上风电提供省级财政支持的省份。 按照《通知》,2022年舟山市海上风电发展目标为开工30万千瓦,核准容量100万千瓦,2022年和2023年全省享受海上风电省级财政补贴规模分别按照60万千瓦和150万千瓦控制,以项目全容量并网年份确定相应的补贴标准,按照“先建先得”的原则确定享受省级补贴的项目,直至补贴规模用完。项目补贴期限为10年,从项目全容量并网的第二年开始,按等效年利用小时数2600小时进行补贴。 与广东和山东提供“省补”的方式类似,浙江海上风电补贴同样是逐年退坡,但从舟山市此次公布的补贴标准来看,其不同点在于,浙江是为海上风电项目按照度电补贴,而另两省则直接按照项目容量补贴。 根据广东省人民政府发布的《促进海上风电有序开发和相关产业可持续发展的实施方案》,2022年起,广东省财政对省管海域未能享受国家补贴的项目进行投资补贴,补贴标准为2022年、2023年、2024年全容量并网项目每千瓦分别补贴1500元、1000元、500元,对2025年起并网的项目不再补贴。山东省能源局副局长邓召军在今年4月公开表示,对2022-2024年建成并网的“十四五”海上风电项目,山东省财政将分别按照每千瓦800元、500元、300元的标准给予补贴,补贴规模分别不超过200万千瓦、340万千瓦、160万千瓦。 助力改善海上风电经济性 厦门大学经济学院中国能源经济研究中心教授孙传旺指出,补贴是推动可再生能源市场化发展的重要方式,但现阶段海上风电成本仍然较高,为直面海上风电平价压力,仍需政府提供一定的资金支持,保障稳定的装机规模增长。在此背景下,“省补”出台接替“国补”,能够防止“国补”退出导致的资金流断裂情况出现,在一定程度上延续了行业增长态势,稳定了市场预期,有利于推动技术进步与成本下降。 “‘省补’的出台势必会对本省的海上风电发展有正向的刺激作用,尤其是广东和山东出台的‘省补’都按项目容量进行一次性补贴,更可以直接地帮助项目降低成本。”睿咨得能源可再生能源分析师朱祎聪告诉记者。 从补贴力度上看,目前三省“省补”力度实际上远低于此前的“国补”,但在业内看来,这一补贴力度已足够提振市场,并吸引投资者。朱祎聪指出:“目前的补贴力度虽然总体上不如之前‘国补’的力度大,但可以使投资方更快回收资金,对投资者同样具有吸引力。三省的补贴也都以不同形式进行阶梯式退补,既能在现阶段帮助提升海上风电项目的经济性,又可以持续刺激产业链各个环节进一步降本增效,早日实现平价上网。相较于没有补贴的省份,出台‘省补’的几个省份也能够吸引更多投资方,选择更为优质的企业,对本省的产业发展也会有很好的促进作用。” 风电设备供应商大金重工指出,政策支持与电价补贴有效地促进了我国风电产业投入提高、产量提升、技术进步、成本下降,为最终实现平价上网奠定了发展基础。虽然海上风电2022年起不再享受国家补贴,但是鼓励地方继续补贴建设海上风电,风电行业政策趋势整体向好。据预计,未来10年,中国海上风电市场的年复合增长率将达到27%,累计并网装机将达到1亿千瓦。 海上风电平价仍需多方着力 密集的支持政策出台催热了海上风电市场,近几个月来海上风电项目招标也持续火热。据不完全统计,今年第二季度新增海上风电启动项目招标规模可达330万千瓦,增速超出业界预期。更为值得关注的是,近期海上风电项目风机中标价格也呈现大幅下降趋势,据浙商证券数据,目前,海上风机平均招标价格已下行至约3680元/千瓦,与2020年海上风机7003元/千瓦的平均招标价格相比,降幅达到一半。 朱祎聪认为,前两年的海上风电装机潮推动了风机价格的下降,在海上风电进入无“国补”时代后,进一步降本增效的需求更为强烈,风机价格的持续下降不仅能够使得海上风电项目尽早实现平价,也能推动产业链的持续创新。 海上风电的平价却不仅依赖于设备。有测算显示,2020年,海上风电投资成本结构中,风电机组占比仅约为35%,其余为电力设施、安装工程、海上桩基等。 对此,孙传旺指出,除削减风机成本外,海上风电项目还需协同产业链各个环节降本,比如,静态投资占比高的基础和海缆领域,也是未来降成本的主要着力点,与此同时,还需在安装环节与风电场规模化两个环节降本。“江苏、广东、福建等地的海上风电完全成本约在1.5万元/千瓦—1.8万元/千瓦之间,如果要实现7%的收益率,海上风电完全成本需降至1万元/千瓦左右,最终能否实现项目平价,仍需结合当地基准电价和‘省补’额度进行测算。”
