Waukesha 4.2 MW CoGen Plant Ships to Canada
Diesel Service & Supply recently shipped a large industrial 4.2 megawatt cogeneration system to Canada. This package had two 2100 kW natural gas generators and full cogentation capabilities with chillers, boilers, urea tanks and more. Read how the system works here.
What is Cogeneration?
Cogeneration is the production of two or more forms of energy from a single fuel source. It is often called combined heat and power, distributed energy, or recycled energy. There are many styles of cogeneration systems in use today. The power generation industry is widely associated with cogeneration systems. This design of a system does not allow heat to escape into the atmosphere. Instead, it uses the heat, which is a byproduct of generating power to other resources.
Natural Gas (NG) generator powered systems used for cogeneration systems pass exhaust gas into equipment that reclaims it. When a NG generator is connected to a utility gas supply, it has almost unlimited operating time. An exhaust heat recovery system is used to utilize the heat from the exhaust.
The absorption chiller is driven by exhaust gas from the engine combustion process. The chiller and its components, such as condensers, evaporators, and cooling towers, provide a cooling medium for an air-conditioned space. A basic engine-driven cogeneration system can use exhaust gas to provide cooling for a building. There are many other components within the exhaust gas recovery system used for cooling.
Generator paralleling panels allow two generators to operate in parallel or be used in a redundant configuration. When generators are operated in parallel, the voltage is the same, and amperage is additive (generators same capacity). This means the voltage will remain the same, but the capacity of the generators is combined. Distribution and circuit protection panels divide the load into individual circuits. Control panels for systems such as chillers are also interfaced to complete the pieces of operational equipment. Remote greenhouses and large industrial complexes are some of the industries using this technology to supply heat in the winter months and cooling in the summer months.
Solution Provides Environmentally Friendly Natural Gas with Combined Heat & Power Cogen System for Canada
With over 35 years in the generator business, our large inventory included 4.2 MW Continuous Waukesha power generating system with an exhaust recovery system included. A customer with a remotely located business in Canada purchased the complete, new system. Our international shipping services recently delivered this system to the client. This required multiple trucks to complete. Each piece of equipment had to be loaded using yard equipment and then protected for the trip to Canada. Loading these trucks with different sizes and weights of equipment can be equated to a huge puzzle with lots of pieces that only will fit one way.
We have a large selection of all styles and capacities of generators. We offer low-hour pre-owned, surplus, and new generators. Go to Inventory

(2) Waukesha 2100 kW Generators are Primary Component
Although it requires all equipment to work together in a properly operating cogeneration system, generators can be considered the heart of the system. A standard system can be divided into the below categories:
- Generators - Provide electricity for the building or complex. Engine Exhaust and cooling water are both heat sources that can be reclaimed. The main function of this system is the production of electricity. Heat reclamation is a byproduct.
- Heat Reclamation - Exhaust gases can be reclaimed using an absorption or adsorption chiller for building cooling. Engine coolant can be routed through heat exchangers (HEX) to provide a heating medium for hot water heaters.
Generator Supplies Resources
All engine-powered generators produce heat through exhaust gases and cooling water. Complete cogeneration systems are designed to operate with published savings through cooling and heating. Often, these systems are designed for continuous operations. The always generator supplies electrical power as its' primary purpose.
Emergency and backup generators can also supply heat when the power fails. It has become a common industry practice to use exhaust and/or cooling water for building heating during a utility power failure. Having the additional resource reduces the grid associated services. The use of available resources that were previously discarded is gaining popularity because of financial and environmental associated benefits.
A building with an existing backup power system can be retrofitted to utilize generator resources. Upgrading the generator and distribution are the first steps. Once generator(s) are selected, the components for reclamation can be selected. It is important not to exceed manufacturer's specifications when selecting components. Always consult a professional to review your design or to design the system to need requirements.
Indoor, outdoor, and portable are the three styles of generators manufactured today. Indoor generators are commonly used in cogeneration efforts. However, outdoor units can have exhaust and cooling water modifications installed to reclaim the heat. Modifications to the systems can not impede or restrict generator operations. Some generator manufacturers have portable cogeneration units on the table.
