Cummins Power Generation provides complete build-install-operate solution for another Australian peaking power plant
|
|
The first challenge: The site was already occupied by the 20 MW Lonsdale Power Station, which had to be decommissioned, refurbished and moved to adjacent land. Then, as with the other IEA peaking power plants, there were strict environmental standards for noise and emissions. At the same time, the new plant had to be able to meet short-term demands for electricity by starting within five minutes. The result is 57 MW of peaking power, delivered by 36 diesel-fueled generator sets managed by a DMC300 Master Controller. The case history is here.

Check out these tips designed to help you understand Cummins generator sets and their applications.
|
|
Power generation systems and equipment are classified by type, or class. For example, it can be classified as standby / emergency, Power Prime / Peak Hour, or continuous. It is very important to understand that the type of generation system and classification depend on the application. Emergency system: This type of equipment and system is designed to supply power and lighting for short periods. It will allow for the safe evacuation of buildings, the continued operation of emergency communications systems used for public safety, and for the continued operation of life support, and other medical equipment needed by people requiring special care. Legally required: These systems are typically designed to supply power and lighting for short periods, as a means to prevent accidents or facilitate firefighting operations. Optional standby: Optional standby systems are installed where safety is not a critical factor, but rather where a power outage can cause inconvenience or loss of business. Such systems are typically installed in data processing centers, farms, commercial or industrial buildings and residences.
Prime Power: Prime power installations use generator sets to produce localized power so the need or application need not rely on energy supplied by the public utility. A simple prime power system uses at least two generator sets and a commuting switch to transfer energy loads between them. Typically, one of the generator sets handles a variable load, while the other serves as a reserve. Peaking Power: Peaking-power facilities use localized power generation to reduce utility energy usage or stabilize electricity usage during peak hours, as a means to save money on energy costs. Power generation equipment installed for standby purposes can also be used for peak power needs. Cost reduction (seasonal use): Peak-time systems provide power using generator sets to reduce electricity costs. With the operation of generator sets during seasonal peak periods, users can save up to 30% of their total energy costs at the end of the month. Continuous basic load: Facilities for continuous basic loads use local generation to supply ongoing energy (kW), usually by using equipment for interconnection with the power utility grid. Cogeneration: Cogeneration is the use of directly generated electricity and the use of radiated exhaust heat to replace energy provided by the utility. The radiated heat is recaptured and used directly for heating, or otherwise converted back into electricity. |
Yet another success story: Cummins energy working for Sony in Brazil.
|
|
To put this application in place, we enjoyed the support of our local distributor, Powertech. Sony’s energy is now ensured, and the company will be able to save up to 30% on its current bills. The savings is due in part due to Cummins’ total solutions focus.

Fishers Island, New York, gets emergency and peaking power from Connecticut utility and Cummins Power Generation
|
|
Because Fishers Island, New York, is close to Connecticut, it is served by the Connecticut Municipal Electrical Energy Co-op, or CMEEC. Recently, CMEEC installed a 2.5 MW generator set from Cummins Power Generation to provide emergency and peaking power for the island’s residents. Before that, power was provided by means of a cable running from a utility generating facility in Connecticut — along the floor of Long Island Sound — two miles out to the island. This cable is susceptible to getting snagged by ships’ anchors, and if the cable did break, power to the island would be knocked out for some time. It would take months to repair or replace the cable, and several days just to get some form of portable power generation set up and connected to the distribution system on the island. With the new system, Fishers Island will be able to start the generator set and supply power within an hour of a mainland power interruption. Beyond supplying standby power, CMEEC also wanted to reduce the amount of electricity imported to the island during periods of peak usage. So the Cummins Power Generation system will also be used to handle peak energy demands, which typically occur during summer weekends. The new generator set is capable of providing sufficient energy to power the whole island, even during the summer, when the population swells from about 300 year-round residents to 2,000 people and demand for power reaches 2 MW.

Energy Company Expands its Operations with Cummins Power Generation
Mexican retail food chain selects Cummins Power Generation for peak shaving power
|
|
Calimax is a popular Mexican grocery store chain with more than 50 stores that vary in size from 1,000 to 4,500 square meters. Calimax selected Cummins Power Generation equipment to provide prime power for its giant distribution center to reduce operating costs during peak hours. Headquartered in Tijuana, Calimax has a strong presence in Mexico’s northwest region, including Tijuana, Mexicali, Ensenada, Rosarito and Tecate in the State of Baja California, as well as San Luis Rio Colorado in the state of Sonora. Both of these Mexican states share a border with the United States. The entire chain of Calimax stores is supplied from a large distribution center in suburban Tijuana. The center covers 48,000 square meters and is capable of storing 16,000 different products. Calimax wanted to reduce the energy costs of running this large facility. The local Cummins distributor, Cummins de Baja, developed a solution that reduces the cost of electricity at peak times by allowing the company to generate its own power with seven Model DQDAC high range generator sets. Seven DQDAC model generator sets were installed at the Calimax distribution facility. This model is rated at 300 kW standby and has a 270 kW prime power rating. When the cost of power from the local utility is high, Calimax can run these generator sets to produce their own electricity and save money. |
SuperFrango builds modern incubator with help from Cummins Power Generation
|

Brazil has one of the world’s most modern and efficient poultry industries. The São Salvador Poultry Processing Plant, better known as SuperFrango (SuperChicken), is a pioneer in modern poultry-raising systems in the country’s central region. The company, headquartered in Itaberaí, Brazil, was founded in 1970 through a partnership between friends Carlos Vieira da Cunha and José Carlos de Souza. Prime technology Power for growth

nd construction, and a $12.6 million investment, SuperFrango opened its new 14,000-square meter plant on a 100,000-square meter site. The plant provides jobs for about 1,400 employees.
The Cummins Power Generation peak power system helps SuperFrango meet its electricity needs by monitoring utility power, starting and paralleling the generators if power fails, and transferring power from the utility to the generators as needed. When time of day electric costs require it, the system will automatically start the generators, parallel them to the utility, and control their power output so that load on the utility (and costs) are minimized. The generators provided are sufficient to operate the entire facility. When it’s time to shut them down, the system synchronizes and parallels the generators to the utility, transfers the load back to the utility, disconnects and cools down the generators, and leaves them ready to start again when they are needed.
