What is Combined Heat and Power?
Blake Equipment has provided Combined heat and power (CHP) to the Northeast for decades. CHP, also known as cogeneration, is the simultaneous production of Electricity and Steam( for heat and processes) from burning a single source of energy such as natural gas, biomass, biogas, coal,oil or from waste heat. A CHP system can greatly increase a facility’s operational efficiency, decrease energy costs and reduce environmentally harmful emissions. It is a form of local or distributed generation(DG) as heat and power production take place at or near the point of consumption. The closer a power plant is to the point of use the higher the efficiency.
Would CHP benefit my facility?
If you answer “Yes” to 3 or more of these questions, your facility may be a good candidate for CHP. Contact your Blake Equipment representative for more information.
- Do you pay more than $.07/ kilowatt-hour on average for electricity (including generation, transmission and distribution)?
- Are you concerned about the impact of current or future energy costs on your business?
- Is your facility located in a deregulated electricity market?
- Are you concerned about power reliability? Is there a substantial financial impact to your business if the power goes out for 1 hour? For 5 minutes?
- Does your facility operate for more than 5,000 hours/year?
- Do you have thermal loads throughout the year (including steam, hot water, chilled water, hot air, etc.)?
- Does your facility have an existing central plant?
- Do you expect to replace, upgrade or retrofit central plant equipment within the next 3 to 5 years?
- Do you anticipate a facility expansion or new construction project within the next 3 to 5 years?
- Have you already implemented energy efficiency measures and still have high energy costs?
- Are you interested in reducing your facility’s impact on the environment?
Next ask the financial questions:
- What is the up front capital investment required to install CHP or replace an existing boiler?
- What are the anticipated operations and maintenance (O&M) cost?
- What savings will result from not paying for grid-provided electricity and separate thermal energy?
- What are the monetary and other benefits that result from maintaining critical operations during grid disruptions?
How much money is available in state, local, utility or federal financial incentives to support the project?
- How will state policies and requirements governing utility actions that impact CHP system operation?
- Will a CHP project meet organizational financial targets?

The following sectors commonly benefit from Combined Heat and Power Systems:
- Industrial manufacturers—chemical, refining, ethanol, pulp and paper, food processing, glass manufacturing
- Institutions—colleges and universities, hospitals, prisons, military bases
- Commercial buildings—hotels and casinos, airports, high-tech campuses, large office buildings, nursing homes
- Municipal—district energy systems, wastewater treatment facilities, K–12 schools
- Residential—multi-family housing, planned communities
CHP isn’t for everyone, nor is it the only “Green Steam” solution. Blake can help you determine if CHP or another energy solution will work best for you. Call you local Blake Representative for more information.
How does CHP work?
Most CHP systems are designed to meet the heat demand of the energy user since this leads to the most efficient systems.
- Larger facilities generally use customized systems.
- Smaller-scale applications can use prepackaged units.
- Cogeneration Systems are defined by their Prime Mover.
The prime mover consumes fuel to power a generator to produce electricity or to drive rotating equipment. Prime movers also produce thermal energy that can be captured and used for other on-site processes such as generating steam or hot water, heating air for drying, or chilling water for cooling. There are currently five primary, commercially available prime movers: gas turbines, steam turbines, reciprocating engines, microturbines, and fuel cells. Contact Blake for more information.
There are basically two types of Combined Heat and Power. A system can make steam first with electricity as a by-product or make electricity first with steam as a by-product. Below is a closer look at how the two systems work:
Bottoming Cycle/Heat First – Most common in Process Industries
Fuel is first used to produce useful heat for a manufacturing process and some portion of the exhaust heat is then used to generate electricity.
ELECTRICITY IS A BYPRODUCT.
Fuel is first used to generate electricity or mechanical energy at the facility and a portion of the waste heat from power generation is then used to provide useful thermal energy.
HEAT IS A BYPRODUCT.
