「英中对照」David Energy小型插电电池如何助纽约云厨房Wonder21站点半年省2万美元能源成本

Ghost kitchen startup Wonder has saved about $20,000 in energy costs since it installed stationary plug-in batteries at some of its sites six months ago. The suitcase-sized batteries were provided at no cost by David Energy, a retail energy company that tries to help facilities lower their rates by shaving peak energy use. David Energy makes its money on the supplier margin from the energy it sells and by taking a share of the value its customers generate from participating in utility demand-response programs.幽灵厨房初创公司 Wonder 六个月前在部分场所安装了固定式插入电池，此后已节省约 20,000 美元能源成本。这些手提箱大小的电池由零售能源公司 David Energy 免费提供，该公司试图通过削减峰值用电帮助场所降低费率。David Energy 的收入来自其所售能源的供应商利润，以及从客户参与公用事业公司需求响应计划所产生价值中获得的分成。

“Our number one goal was to figure out how we can reduce our utility bills, shave the peaks off of our utility usage,” said Abe Nasrallah, Wonder's senior vice president of real estate and development. “We were looking for any kind of solution.”“我们的首要目标是弄清如何降低电费账单、削减用电峰值，”Wonder 房地产与开发高级副总裁 Abe Nasrallah 说。“我们当时在寻找任何类型的解决方案。”

Wonder operates out of 160 locations in the Northeast United States. It installed the batteries in 21 of its New York City sites, with plans to bring more locations into the program.  Wonder 在美国东北部经营 160 个网点。该公司已在其纽约市的 21 个场所安装电池，并计划让更多网点加入该计划。  

Each battery provides 2 kilowatts/6kWh of energy, according to David Energy. They’re typically clustered into pods of three batteries, connected to a 20A circuit breaker. Depending on the size of the site, half a dozen pods might be installed, generating up to 50kwh in energy. As many as three pods might be connected to a service panel. 据 David Energy 称，每块电池可提供 2 千瓦/6kWh 电能。它们通常三块组成一组，连接到 20A 断路器。根据场所规模，可能安装六组，产生最高 50kwh 电能。一个配电箱最多可连接三组。 

“We tested it at one site and it was extremely simple to install,” Nasrallah told Facilities Dive in an interview. “Just plug it into an extended outlet, which is great. After we tested out one, we put it in 21 locations.”“我们在一个场所进行了测试，安装极其简单，”Nasrallah 在接受 Facilities Dive 采访时表示。“只需把它插入延长插座，这一点很好。测试一个之后，我们就在 21 个场所进行了安装。”

The $20,000 in savings is 3% to 5% of its energy costs for the 21 locations, Nasrallah said.  Nasrallah 表示，20,000 美元的节省额占这 21 个场所能源成本的 3% 至 5%。  

Walmart’s former head of e-commerce Marc Lore launched Wonder in 2023. The delivery-app company partners with restaurants to produce the restaurants’ menu items in Wonder’s kitchens for home delivery.Walmart 前电子商务负责人 Marc Lore 于 2023 年创立了 Wonder。这家配送应用公司与餐厅合作，在 Wonder 的厨房制作餐厅的菜单菜品，用于配送到户。

The kitchens are all-electric, making rate management an important part of the company’s cost strategy, Nasrallah said.Nasrallah 称，这些厨房采用全电气化设计，因此费率管理是公司成本战略的重要组成部分。

“Part of [the all-electric strategy] had to do with what the business model was,” Nasrallah said. “The other part was, for a period of time, there were gas moratoriums in New York City [and] a lot of new developments just didn’t have gas. So, having built our first few units in the city, it made it easier to just continue down the path of all-electric.”“[全电气化战略]的一部分与商业模式有关，”Nasrallah 说。“另一部分是，曾有一段时间，纽约市实施天然气暂停令，[而且]许多新建项目根本没有天然气。因此，我们在该市建成最初几个门店后，继续走全电气化路线就更容易了。”

The batteries face fewer regulatory constraints than permanent battery storage systems and are easy to install, especially when compared to permanent battery systems that, because of their size, are impractical to install in a dense metropolitan area like New York City, David Energy CEO James McGinniss told Facilities Dive.  David Energy 首席执行官 James McGinniss 告诉 Facilities Dive，与永久性电池存储系统相比，这些电池面临的监管约束更少，也更易于安装；尤其是与永久性电池系统相比，后者由于体积原因，在纽约市这样的密集大都市区域并不实际可行。  

“If you think about putting a big battery in Manhattan on a roof or something like that, it’s just logistically impossible,” McGinniss said, “so these new plug-in batteries are what really enable something that’s very fast and easy to do.”“想想在曼哈顿的屋顶或类似地方放置一块大电池，这在物流上根本不可能，”麦金尼斯说，“所以这些新型插电式电池才真正让事情变得非常快速、简单易行。”

Depending on the building’s existing electricity infrastructure, installation can take little time, he said. “We just take an open breaker slot, run some conduit and plug in there,” McGinniss said. “It’s on its own dedicated circuit, so it doesn’t interfere with any of the other loads in the building.”他说，根据建筑现有的电力基础设施，安装可能用不了多少时间。“我们只需找一个空置的断路器槽位，铺设一些导管，然后插在那里，”麦金尼斯说。“它使用自己的专用电路，因此不会干扰建筑内的任何其他负载。”

At one of Wonder’s locations, there were several service panels, enough for David Energy to deploy two dozen batteries in “eight pods of three,” McGinniss said. “They’re going right into the panels.”麦金尼斯说，在Wonder的一个场地有几个配电盘，足以让David Energy部署24块电池，分为“8个电池组，每组3块”。“它们会直接接入配电盘。”

In addition to shaving peak energy use, David Energy enrolls companies like Wonder into utility demand-response programs to serve as an emergency resource to help the grid reduce energy use during periods of high demand, like during a heat wave. David Energy holds the licenses needed for the companies to serve as energy market participants. 除了削减高峰用电，David Energy还让Wonder等公司加入公用事业公司的需求响应计划，作为应急资源，在热浪等高需求时期帮助电网减少用电。David Energy持有这些公司作为能源市场参与者所需的许可证。 

“We get paid directly by the utility and the market,” McGinniss said. “So, what we’re doing with Wonder helps the broader grid avoid blackouts.” “我们直接由公用事业公司和市场付费，”麦金尼斯说。“所以，我们与Wonder合作所做的事，能帮助更广泛的电网避免停电。” 

David Energy manages the batteries on its platform, using an automated process to determine the optimal times for charging and discharging energy. David Energy在其平台上管理这些电池，使用自动化流程确定充电和放电的最佳时间。 

In New York, McGinniss said, “the 15-minute interval of maximum demand per month [that determines the peak rate] is $40 per kW month, so one of these batteries can save $40 per month if you predict that peak well. We predict those peaks and discharge at those times…. It’s all done with software.”麦金尼斯说，在纽约，“每月决定高峰费率的15分钟最大需量区间为每月每千瓦40美元，因此如果你能很好地预测那个高峰，其中一块电池每月就能节省40美元。我们预测这些高峰，并在那些时段放电……这一切都是通过软件完成的。”

The batteries are lithium iron phosphate, not nickel-based lithium, so their fire risk is minimal, McGinniss said. They’re configured to discharge energy for up to three hours; batteries capable of discharging over five hours are in the works.麦金尼斯说，这些电池采用磷酸铁锂，而非镍基锂电池，因此火灾风险极小。它们的配置最长可放电3小时；能够放电超过5小时的电池也在研发中。

McGinniss said the company is cutting its teeth in what it considers the hardest market for battery deployment — New York City — giving it experience for when it expands to other areas. 麦金尼斯表示，该公司正在它认为电池部署难度最大的市场——纽约市——初试身手，从而为未来扩展到其他地区积累经验。 

We’re “figuring out how to deploy in very dense metropolitan areas,” he said. “That means we think it’s widely applicable for every major metro.”我们正在“弄清如何在人口高度密集的大都市区部署，”他说。“这意味着我们认为它广泛适用于每一个主要大都市。”

Facilities deploying the plug-in batteries range from 500 square feet to 10,000 square feet; managers of buildings bigger than that will want to explore bigger batteries, McGinniss said. That’s not a market David Energy is targeting. “There are enough facilities [up to 10,000 square feet] to try and serve,” he said. “We’ll figure out bigger battery installations later.”麦金尼斯说，部署插电式电池的场所面积从500平方英尺到10,000平方英尺不等；更大建筑的管理者会希望探索更大的电池。那不是David Energy瞄准的市场。“有足够多（不超过10,000平方英尺的）场所可以尝试服务，”他说。“我们以后会研究更大的电池安装。”

The company is working with a solar power developer to become a power producer as well as a retail seller, which McGinniss said will enable it to help companies reduce their energy costs further. 该公司正与一家太阳能发电开发商合作，力图同时成为电力生产商和零售商。McGinniss 表示，这将使其能够帮助企业进一步降低能源成本。 

“We’ll use the batteries at our locations to manage the intermittencies of solar,” he said. “That will lower our energy costs and create opportunities for us to save even more for companies like Wonder, so the more solar we build out, the cheaper our energy buying gets. We’ll start to pass some of those savings on to customers as we get more scale on the solar side.”“我们将在我们的各站点使用电池来管理太阳能的间歇性，”他说。“这将降低我们的能源成本，并为我们创造机会，为 Wonder 这类公司节省更多费用。因此，我们建设的太阳能越多，能源采购就越便宜。随着我们在太阳能业务侧获得更大规模，我们将开始把其中部分节省的费用让利给客户。”
