Combined Heat and Power (CHP) /
Cogeneration
Engineering and Design
CHP can, in the
most suitable cases reduce a consumers total energy cost by up to 40%. However,
it is important to stress that CHP is not viable at all sites and further that
a poor choice of technology could result in inefficient and uneconomic
operation. It is therefore quite important to build a clear picture of what
specific factors determine the feasibility and profitability of a CHP scheme.
It is essential for
companies to have an independent third party do the CHP feasibility study.
Energy Innovation
Ltd is ideally suited to do this work. We have no affiliations with
manufacturers, technologies or developers, and are in a position to give an
unbiased appraisal of the viability of CHP for a particular site.
The Energy
Innovation Ltd. survey takes into account the fact that many host company's'
core business is not power generation.
We offer a fixed price CHP
Feasibility Study / Appraisal and
payback analysis based on current and future Irish energy market conditions.

The
Scope of Work for a typical CHP appraisal is as follows;
Evaluation
of site or factory’s energy usage data and energy costs.- Develop a load factor for the site.
- Determine site heat to power ratio.
- Select a technology and equipment to
match site heat to power ratio.
- Investigation of integration of CHP
plant with existing plant.
- Equipment selection taking into account
cost of equipment, space available.
- Evaluation of redundancy required in
system
- Payback analysis based on selected
equipment taking into account fuel and Operation Maintenance costs.
- Interfaces - a detailed list of
required site interfaces with new equipment.
- Operation and Maintenance - evaluation
of suitability of in-house or contract based on equipment selected and the
host company’s philosophy and capabilities.
- Emissions and environmental aspects
investigation.
- Control system for CHP plant
installation, investigation of possible control philosophy. Investigation
of integration of CHP plant into existing plant control system.
- A comprehensive report of the findings
will be presented, with all supporting documentation and commercial
appraisal of the project.
Combined
Heat and Power, or Cogeneration, is the simultaneous 
production of electricity and heat, whereby the heat produced in
electricity generation is put to good use rather than being wasted. In conventional power generation, about 60%
of the energy input is wasted in this way. By recovering the majority of this
waste heat, energy savings of between 20% and 40% may be achieved. The installation of CHP has been widely
recognised as a key measure to help reduce harmful carbon dioxide emissions
being released to the atmosphere while delivering the same amount of useful
energy.
It is
estimated that for every 1 MW of CHP installed, CO2 emissions are reduced by
1250 tonnes per annum. On balance, cogeneration results in savings of up to 50%
of CO2 emissions compared with
conventional
sources of heat and power.
the
popularity of CHP will increase dramatically.
This
paper outlines how Ireland will meet its energy requirements in the one of
Europe’s fastest growing economies, in an environmentally sustainable way. It
also describes how Ireland’s policy for limiting energy related CO2 emissions,
in line with international agreements such as the Kyoto protocol. It
specifically mentions CHP as a recommended technology for 
reducing CO2 emissions.
Currently
Ireland has the lowest level of CHP generated electricity in Europe, at only
2%. The installed CHP capacity is currently 111 MW(e). With the recent
de-regulation of 26% of the electricity market, and the high economic growth
rate in Ireland, there is potential to increase this to 500 MW(e). This would
be 12% of the electricity supply capacity, in line with current European trends.
Many
companies are understandably reluctant to take advantage of the opportunities.
Power generation is not their core business, and would mean more work for
already scarce resources. This is where Energy Innovation can help.
It is
essential for companies to have an independent third party do the CHP project
appraisal. It is important that this independent third party has practical
experience of power generation and thermal plant design, selection and
installation.
It is
important that the CHP appraisal takes into account the special requirements of
the host plant, and that the CHP plant should become an integrated part of the
host plant.

Innovation Ltd is ideally suited to do this work. We have no affiliations with
manufacturers, technologies or developers, and are in a position to give an
unbiased appraisal of the viability of CHP for a particular site.
