Cummins standby power system keeps taps flowing and lowers costs

A large regional water treatment plant in west-central Michigan, not far from the shores of Lake Michigan, wanted to ensure that water would continue flowing to more than 200,000 residents even if the electric utility failed, so it installed a standby power system from Cummins Power Generation to prevent service interruptions. The standby system also helps the water treatment plant save money on its electric bills by generating its own lower-cost power during the electric utility’s summer peak demand periods – when lawn watering pushes water demand to as much as 80 million gallons per day. 

Whenever power to the plant is to be interrupted because of summer peak demand, the electric utility notifies the plant 24 hours in advance. During any given summer, the power curtailments during peak demand periods may happen only six or seven times, but they occur during the lawn-watering season when water demand is the highest. However, the generators have enough power capacity to operate the plant even when the demand for water is high. Under the rate agreement with the utility, the plant also is required to limit the amount of power it consumes between the hours of 11:00 a.m. and 7:00 p.m., Monday through Friday. If the plant needs more power during that timeframe, it can generate power in parallel with the utility and just shed a portion of the plant’s load.

Cummins Power Generation awarded the highest recognition from the China data center industry


Cummins Power Generation (CPG) has been honored for its first PowerBlocTM project. The China Engineering Construction Standardization Association, China’s most prominent organization defining data center-related industrial standards, awarded CPG as part of the Data Center Scientific and Technological Achievement Awards. The winner’s list was officially announced during the 9th Data Center Standards Summit. 

Launched in May 2021, PowerBloc was designed by the CPG China team and is manufactured in the CPG China plant in Wuhan, a city in central China. PowerBloc integrates diesel units (power systems), water tanks (cooling systems), fuel tanks (fuel systems), silencers (noise reduction systems), electrical switch cabinets (control systems), and fire protection systems in a highly integrated 40-foot standard container. The first of three PowerBloc gensets was installed at customer sites in September. The standard Installation Quality Assurance (IQA) test, 12-hour continuous load and one-hour overload tests were completed with the customer. The results not only validated 10 square meters of space saving compared to the traditional containerized unit, but demonstrated extra stable operation, low noise, low emission, and excellent performance of this innovative solution.

The PowerBloc project and its remarkable technical innovation has set a new benchmark for standby power in the data center field, especially the containerized area. The award represents the highest of its kind in the China data center industry.

“The concept, design, development and application of PowerBloc is just another vivid example of how our people live Cummins’ vision of innovating for our customers to power their success,” said Wang Lei, General Manager of CPG China. “The driver for this solution was to erase the pain point for our customers in the data center industry. The applause from the customers and the recognition from the industry gives us more confidence to further innovate value-added solutions for this industry.”

During the Summit, the China Data Center Committee also released a Data Center Containerized Diesel Generator Set Technical White Paper, which was co-authored with CPG. Cummins interpreted in detail the design elements, the problems existing in the application and the future development direction for containerized gensets serving as standby power systems.

CPG also utilized this opportunity to showcase its unique capabilities in providing power systems for data centers. The CPG booth attracted many participants from the design institutions that provide power system planning and design. The event was webcast and drew great attention from the public.

CPG has kept the leading position as the diesel genset provider in the China data center industry and continued its reputation as a lifecycle solution provider. Key customers include China Telecom, China Mobile, China Unicom, Alibaba, Tencent and ByteDance.

Home Generator Safety Checklist

Home Generator Safety Tips - Cummins

Follow these home generator safety tips when preparing your home and family for long-term power outages.

With a little more than one month left on the already tumultuous Atlantic hurricane season, not to mention the likelihood of severe winter storms on the horizon, now is the time for power outage preparation

Preparing for long term outages is important, and if you have already taken the step to ensure continuous emergency power by purchasing a generator, consider the steps you need to take to safely operate a backup home generator. 

The biggest risk of home generators is carbon monoxide (CO) gas. It is called “the silent killer” because it is odorless and colorless, meaning that most people inhaling it don’t even realize until it is too late. Symptoms of CO poisoning can look a lot like the flu, and in severe cases, it can cause permanent brain damage or death. CO can be especially dangerous for people who are sleeping or intoxicated.

Here are a few tips for keeping your family safe while operating a generator during your next power outage.

Portable Gas or Diesel Generators Safety Tips:

  1. Always follow manufacturer instructions when setting up a generator.
  2. Never use a generator inside your home or garage. They should be used outdoors in well-ventilated areas that are at least 20 feet away from any homes or dwellings.
  3. Look for any places air can enter the home near your unit and ensure that those are properly closed and sealed off. This includes windows or doors, air intakes, nearby dryer vents or crawl spaces.
  4. Reliable, approved, and operable battery powered CO detector alarms should be installed in proper locations on each floor in the home as specified by the manufacturer. 
  5. Give the generator a break that allows for any concentrated exhaust to clear away from the area. Open your windows and doors during this break to air out any concentration that may have collected in your home.
  6. Ensure that your generator is being appropriately maintained, including regular oil changes. 

Permanently Installed Gas or Diesel Generators Safety Tips:

  1. Install the generator outdoors only.  Work with a professional installer (link to to locate the generator away from windows, doors, and other openings to the house where exhaust gases will disperse away from the house or occupied areas.
  2. Install all parts of the generator enclosure at least 60 inches from any openings in walls of structures that may be occupied.  Examples of wall openings include, but are not limited to, operable windows, doors, dryer vents, fresh air intakes for heaters, etc.
  3. Look for any places air can enter the home near your unit and ensure that those are properly closed and sealed off. This includes, but not limited to, windows or doors, air intakes, nearby dryer vents or crawl spaces. Your generator must be located such that exhaust gases are not able to accumulate in an occupied area.
  4. Ensure that generators are used, maintained, and operated in accordance with manufacturer recommendations. If there is a concern that the installation standards have not been met, get an appropriate party, like the installer, out to inspect it.
  5. Give the generator a break that allows for any concentrated exhaust to clear away from the area. Open your windows and doors during this break to air out any concentration that may have collected in your home.
  6. Check the exhaust system for corrosion, obstruction, and leaks every time you start the generator and every eight hours when run continuously.
  7. Ensure that your generator is being appropriately maintained, including regular oil changes.
  8. Reliable, approved, and operable battery powered CO detector alarms should be installed in proper locations on each floor in the home as specified by the manufacturer.

Cummins home generators are extremely quiet, aesthetically pleasing and remotely accessible. If you have not yet taken the step to purchase a backup generator, consider scheduling a painless home assessment with your nearest Cummins dealer. In just a few minutes you can know exactly how little the ultimate peace of mind can cost.

Компании Cummins Power Generation исполняется 100 лет

D.W. Onan and sons Robert and C. Warren with original Ten Lite 1926

В этом году компания Cummins празднует 100-летие с момента основания подразделения Power Generation. Все началось в 1920 году с создания Дэвидом У. Онаном семейного предприятия под названием Onan Corporation.

«История компании Onan во многом схожа с историей Cummins Inc.. У ее истоков стоял предприниматель с коммерческой идеей и большими планами на будущее. Компания, которую Дэвид Онан основал как небольшое предприятие в штате Миннесота (США), успешно развивалась в течение 100 лет и стала мировым лидером в своей отрасли», – говорит Алекс Савелли, исполнительный директор подразделения Cummins Power Generation (CPG).

Как и Клесси Камминз, Дэвид Онан был новатором и высококлассным специалистом. Проработав десять лет в автомобильной ремонтной мастерской, Дэвид решил попробовать заняться предпринимательством, учредив компанию Onan Corporation в 1920 году. В то время его единственным штатным сотрудником был П. Дайк. В наши дни продукция CPG проектируется в четырех технических центрах и выпускается на шести заводах по всему миру. Итого, в компании Cummins работает более 5 000 сотрудников подразделения Power Generation; создана глобальная сервисная сеть.

Прежде чем стать одним из глобальных лидеров на рынке генераторных установок, в Cummins Inc. произошло множество важных событий. «Приобретение компании Onan Corporation в 1992 году и компании Power Group International (PGI или «Petbow») в 1994 году были важнейшими вехами в истории компании Cummins. Ранее мы были поставщиком двигателей для приводов генераторных установок, а теперь мы стали международным производителем комплектного оборудования для генераторных установок. Интеграция с компаниями Onan и Petbow открыла новые горизонты для «мощности компании Cummins»», – говорит Джино Бутера, вице-президент CPG.

В настоящее время компания Cummins сочетает в себе умение работать на рынке с современными инженерными и производственными технологиями, давая миру безотказные решения для широкого ряда различных применений. Везде: от крупнейшей в мире шахты по добыче железной руды вблизи Северного полярного круга до самых отдаленных мест в бразильских джунглях, от центров широкомасштабной обработки данных до автофургонов для проживания в лесной глуши вдали от цивилизации, компания Cummins надежно обеспечивает заказчиков в электроэнергией, вне зависимости от их местонахождения и направления перемещения.

Новаторский дух Дэвида Онана по-прежнему жив. Он был не только механиком-энтузиастом, но и гуманистом. Сегодня забота о заказчиках – это корпоративная ценность, пронесенная через 100-летнюю историю. Как заметил Дж. Ирвин Миллер: «Клиентов не интересует, сколько вы знаете, до тех пор, пока они не узнают, как вы о них заботитесь». Этот подход по-прежнему действует в компании. «Нам действительно должно нравиться, чем мы занимаемся, и мы должны четко представлять, почему мы этим занимались последние 100 лет и почему мы продолжим этим заниматься следующий век. Этот подход применяется в отношениях с нашими заказчиками, с нашими сотрудниками и с жителями городов, в которых мы работаем», – говорит Даг Санкел, директора завода в г. Фридли (штат Миннесота, США). И добавляет: «Мы ежедневно прилагаем максимум усилий для превращения нашего завода в производственный объект компании Cummins мирового класса и для создания дополнительных производственных мощностей для выполнения новых заказов. Увеличивая нашу долю на рынке и улучшая характеристики некоторых из наших существующих моделей, мы также готовимся к переходу на следующий уровень технологического развития».

С 1920 года, когда была учреждена компания Onan Corporation, в мире произошли значительные изменения. В современном мире способы производства и потребления электроэнергии меняются постоянно. Такие заметные тенденции развития, как децентрализация коммунальных служб, использование возобновляемых источников топлива, а также новые требования к цифровизации являются определяющими для нашей конкурентоспособности и совершенствования. Cummins Power Generation празднует юбилей своего основания и своей приверженности разработке нового поколения технологий для выработки электроэнергии. Приглашаем Вас вместе с компанией Cummins отметить первый 100-летний юбилей подразделения Power Generation и обсудить перспективы на следующие 100 лет.
