Recent Expansion of Cogeneration
Expansion of cogeneration in France, Germany, Italy and the UK
alone would effectively
double the existing primary fuel savings by 2030. This is the
finding of the IEA’s recent modelling
of cogeneration expansion for the G8 countries. The savings
equate to a cogenerated electricity expansion in these countries from 155.69
Twh today to 465 Twh in
2030, and would result in between 16% and 29% of each countries
total electricity being
generated by cogeneration in 2030.
The IEA study modelled the potential growth of CHP based on the
assumption that with the
right policies in place, growth rates up to the historical
levels achieved by Netherlands,
Denmark and Finland are possible. The study concludes:
“There are ….. dramatic efficiency gains that can be realised by
pursuing energy efficiency in
the heat and electricity sectors simultaneously through greater
use of combined heat and
power and district heating and cooling. CHP and DHC include a
family of proven, costeffective
technologies in the industrial, commercial and residential
sectors that merit a closer
look.”
Member States have themselves begun to assess their potential to
expand cogeneration
under the provisions of the Cogeneration Directive. An
additional capacity between 50% and
100% is economically feasible in many member states. Germany in
its national study
reported that over 50% of the country total electricity demand
could be provided through
cogeneration. So far Germany has set a more modest target
(August 20074)
to double
electricity cogeneration by 2020 from supplying 12.5% of the
country’s electricity to 25%, and
has passed supporting legislation accordingly.
