ARES is a multifaceted research program involving engine manufacturers, research laboratories, universities and the government. Cummins is one of three U.S. engine manufacturers to participate in the program that seeks to design engines with improved fuel efficiency and reduced emissions
Cogeneration produces both electricity and useful heat or cooling energy from the same fuel source. Cogneration, also known as Combined Heat and Power (CHP), typically replaces the traditional method of purchasing electricity from the power grid and then burning natural gas or oil in a furnace to produce heat or steam. The concept has been around since Thomas Edison’s first electric generating plant in the 1880s. You’ll find Cogeneration systems today in many modern forms such as at chemical processing plants and the utility providers that supply district heating to buildings in major cities. Facilities that use CHP Cogeneration technology include academic institutions, healthclubs, greenhouses, hotels, hospitals, many types of industrial manufacturers and commercial businesses as well as government facilities.

Successful Cummins automation upgrade to aging Utah pediatric hospital cogeneration plant
|
Primary Children’s Medical Center (PCMC) can boast a century of excellence in pediatric care and recognition as one of the best children’s hospitals in the country. But an aging cogeneration power plant meant high maintenance costs. A new case history documents how technical and space constraints were overcome with a new, more reliable and more automated system.
The hospital wanted a more hands-free, lower-maintenance system that could handle all or almost all of its loads, not just essential equipment. And they wanted to keep a generator set from another supplier that was added several years ago but required a lot of manual intervention in the event of a power outage. The solution provided by Cummins Power Generation and Cummins Rocky Mountain overcame the technical issue of a different winding pitch on the non-Cummins generator set, as well as extremely tight space limitations. Click here to find out how the challenges were solved.

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. |

New case history on Frimley Park Hospital highlights greener power
|
Frimley Park Hospital in Surrey, England, has made a considerable investment in greener energy to reduce its exposure to local utility rates and also to reduce its carbon emissions. A significant part of the hospital’s greener strategy was a tri-generation project featuring a combined heat and power (CHP) plant driven by Cummins Power Generation.
The hospital selected the Cummins solution for its combined benefits of energy savings and price, as well as for the project experience of the Cummins Power Generation team. Working on an accelerated timeline and in tight quarters, Cummins installed a 1370 kW lean-burn natural gas generator set with controls. In addition to generating electricity for the hospital, the system captures heat from the engine water jacket, oil coolers and exhaust, all of which is then used by absorption chillers and condensing coolers to heat and cool the building. The forward-thinking decision to select a cogeneration solution will reap long-term financial and environmental rewards for the hospital. The case history is available here

New video highlights single-source project capabilities of Energy Solutions Business
|
A new video from the Energy Solutions Business (ESB) unit of the Power Projects Group illustrates the breadth of total project capabilities and solutions that the business unit can deliver to meet customer needs around the world. As Tony Satterthwaite, president of Cummins Power Generation, notes in the video, ESB offers combined heat and power (CHP) solutions that are simple in concept but quite challenging to implement in practice. Partnering with local specialists, ESB can handle site surveys, civil engineering work, mechanical and electrical engineering, and project management. It can even build and operate an on-site power generation facility and sell the output to the customer.
The video touches on ESB project capabilities in several locations across the globe, including Russia, Brazil, Scotland and the U.S. The primary focus of the video is a case history of an ESB project in Port Stanvac, Australia. There was a 10-year-old power generation facility using trailerized generator sets on the site. The customer wanted to build an entirely new plant on the existing site, moving the trailerized units to a nearby location. ESB took on the total project responsibility for moving the existing installation to the new location and building a new 65 MW peaking power plant on the original site. Tony Satterthwaite also notes in the video that CHP customers want three things: a) to save money, b) to reduce their carbon footprint and c) to have dependable systems that allow them to get on with their business. The goal of Cummins ESB is the same: to provide total solutions that customers can count on to make their businesses work. The video is available here. |
Cummins wishes to increase its share in the natural gas powered Generator Set market.
|
Cummins Power Generation sponsored a Training Course for Business Advisers for the natural gas Air Conditioning and Cogeneration Market, organized by ABEGÁS – Brazilian Association of Piped Gas Distribution Companies, from November 10 to 12, in the capital of Pernambuco State, Brazil. According to Cummins applications engineer Gustavo Marchezin, the company would like the knowledge disseminated during the training course to be absorbed by participants who can act in the natural gas applications market more successfully, favoring all companies related to the sector.
Cummins Power Generation’s objective is to increase market share for Generator Sets powered by natural gas, especially in Brazil. “As this is a relatively new market niche in the country, one ingredient for its development is knowledge and dissemination of information, which is fully in line with courses such as this one organized by ABEGÁS,” states Gustavo. This engineer declares that ABEGÁS plays a key role in developing the gas sector “given that it has become a common communications channel operating in line with the needs of the market and companies in the market, fostering debate and action designed to break down or reduce barriers,” he concludes. |
U.S. Department of Energy awards CHP development project to Cummins Power Generation
|
The U.S. Department of Energy awarded Cummins Power Generation with an assignment to develop a low-cost, prepackaged combined heat and power (CHP) or cogeneration system that will help customers reduce energy costs in smaller industrial and commercial applications. It has become increasingly important for companies to find ways to reduce energy consumption and costs. CHP is one solution. The goal of CHP is twofold: to provide reliable power and to use the heat byproduct of the generator’s prime mover for other customer requirements like hot water or building heat. CHP, then, maximizes fuel efficiency by putting up to 85 percent of the energy in the original fuel to productive use. The project represents a joint endeavor with the Cummins Engine Business unit (EBU), which will focus on developing a new 19L natural gas engine. Cummins Power Generation will focus on control designs and thermo-mechanical integration. The project will allow Cummins Power Generation to further its CHP technology, thereby making it more cost-effective for use in smaller applications including schools, office buildings, health clubs/spas and extended-service restaurants. When concluded, the project will result in the highest-efficiency, lowest-emission CHP system for projects less than 1 MW in size. To ensure market success, upon completion of this new Product Proceeding Technology (PPT) project, Cummins Power Projects group will follow Cummins Power Generation’s formal product development process (value package introduction or VPI) to commercialize the final offering. The initial system will be marketed to mainstream end users via the Cummins Energy Solutions Business (ESB) unit, with further commercialization ultimately transitioning to the Cummins distributor network. This joint technology program is an example of Cummins Power Generation’s design leadership and commitment to sustainability through the advancement of efficiencies and the reduction of emissions. |
