What
is CHP (Cooling, Heating and Power)?
Cooling, heating and
power refers to recycling waste heat when producing electricity
and using it to create chilled water, hot water or steam. Chilled
water can be used for air conditioning. Hot water or steam can
then be used for space heating, domestic hot water, industrial
processes or powering dehumidifiers.

Where
do we start to implement a CHP on-site energy system that is customized
to meet our energy needs?
Start with Korridor Capital. Korridor Capital consults with you
to demonstrate the cost savings, reliability and environmental
benefits of a CHP system. We have the expertise of your state’s
energy and environmental laws. We have the financial expertise.
We offer a total solution to finance and design-build the CHP
system. You can outsource these services to our team. We offer
a phased approach for your decision-making with a non-vendor specific
solution that is easy to install. We provide a cost effective,
total solution to meet your energy needs. We consider alternative
energy sources.

How can a CHP
on-site energy system be financed? Korridor
Capital can finance your CHP on-site energy system. The CHP system
can be owned by the energy user, or it can be owned by Korridor
Capital who leases it back to the energy user. Leverage lease
financing can be used. A tax-exempt entity such as a municipality
or county hospital can use tax-exempt financing offered by Korridor
Capital to own its CHP system.

What
equipment is used in a CHP on-site energy system?
A CHP on-site
energy system uses a natural gas fired turbine connected to a
generator to produce electricity. The exhaust from the turbine
is recycled into an absorption chiller to create chilled water
and hot water, or recycled into a heat recovery steam generator
(HRSG) to produce steam and hot water. A desiccant dehumidifier
can be added to the system. The actual configuration is
determined by the thermal and electrical loads of the energy user.

Why is there so much interest in CHP on-site energy systems?
There are several
driving forces behind CHP and the use of it on-site. CHP’s
provide cost savings, reliability, security and at the same
time protect the environment.

Cost savings
are achieved from efficiency gains. The U.S. Department of Energy
and the U.S. Environmental Protection Agency are interested in
CHP because of efficiency gains and improvement of air quality.
When coal is burned at a power plant to produce electricity, less
than a third of the energy content of the fuel is delivered to
customers as useable power. The efficiency is less than 33%. Instead
if a CHP on-site plant captures the energy in the exhaust gas
and uses it for cooling, heating and power, efficiencies between
70 to 80% are achieved. This degree of high efficiency translates
to lower energy costs. Further cost savings are achieved because
there are low transmission or distribution costs. Also alternative
energy sources can be utilized by a CHP system.
Reliability and security concerns have heightened from recent
problems in electrical generation and distribution. With your
own on-site energy system you are in control of your energy supply,
quality and cost. There are no transmission and distribution problems.
Also gas turbine technology has advanced into a mature industry
and is very reliable. Using two or more turbines for the base
load can make the CHP system 99.999% reliable. Security is further
enhanced by using alternative energy sources.
Air quality is improved because CHP’s
emit 50 times less NOx emissions than coal power plants. If natural
gas is used for the CHP, there are no SO2 emissions. Emissions
of particulate matter and VOC’s are significantly less.
Recycling the turbine exhaust reduces CO2 emissions. Alternative
fuels can improve evironmental quality.
