Did You Know?

The traditional model of power generation and distribution is based on central power plants feeding an electrical grid consisting of high voltage transmission lines and low voltage delivery or distribution networks. This traditional model is accompanied with inherent overall inefficiencies including large or base loaded power plants introducing “waste heat” that must be rejected by the thermal power generation.

As a result, fossil powered plants typically deliver only about 30% of the energy contained in the fuel as usuable electricity to end users. The situation is improved somewhat with combined gas cycle power plants, which can deliver up to 50% of the fuel’s energy. Fortunately today, owners have options to improve efficiencies, lower energy spend and obtain independence from outdated utility grids.

Combined Heat & Power (CHP)

The low efficiency of conventional power generation and delivery process makes the option to consider on near-site power generation with the beneficial use of waste heat for heating, domestic hot water, or other thermally-activated equipment.

This method of power generation is broadly labelled as CHP – combined heat and power. Basically, CHP produces both electric and thermal energy onsite and generally behind utiliy meter, converting as much as 85% of the input fuel into useful energy.  

CHP can increase resource energy efficiency and reduce CO2 emissions. CHP systems also improve site electric reliability by reducing or eliminating a building's dependence on the electric power or utility grid, which is vulnerable especially in times of natural disasters or high usage periods. 
Located in Seaford, Delaware, the Seaford High School expansion project features a 65,000-square-foot
addition to an existing 150,000-square-foot school, as well as a new central plant with condensing gas
boilers and a new absorption chiller. The cogeneration system can produce 100 kilowatts of continuous
electric power and approximately 700,000 Btu/hr of usable thermal output.

The heat is used for the first stage of heating for the building and provides 40 tons of chilled water,
offsetting at least 15% of the school’s cooling needs. In addition, the engineering models demonstrated
an overall reduction in the school’s utility costs to levels below that of original but new size facility!

Is CHP Right For You?

Answering "yes" to any of the following questions indicates your facility/operation may be a good candidate for CHP:

Do you pay more than $0.10 per kWh 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 the reliability of your facility's electricity supply?

Would there be substantial business, safety, or health impacts if the electricity supply were interrupted?

Does your facility operate for more than 5,000 hours per year?

Do you have thermal loads throughout the year (such as steam, hot water, chilled water, or hot air)?

Do you expect to replace, upgrade, or retrofit central plant equipment (such as generators, boilers, and chillers) 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?
