BUCHAREST SUD CHPP
PROJECT
The prime objective of the Bucharest South CHPP is to supply
the required heat to the City of Bucharest district heating
network. The electrical output then becomes a by product to
generate such heat requirement. Current high level international
price of natural gas which is the prime fuel for the project
makes it unfeasible to finance such investment as a merchant
plant. Therefore the investors, likewise in other EU member
countries, recommend that the project adhering to the framework
of the EU Directive 8/2004/EC to be able to arise with an
economically sustainable proposal.
The proposed plant configuration will consist of one medium
size gas turbine and one extraction-backpressure steam turbine.
This is the most economical solution even if supplementary
firing is necessary to achieve the required district heating
demand especially during winter season. With a gas turbine
size in the range of 57 to 80 MW, the plant will be operated
at or near full load for most of the winter and transition
periods and may be operated at part load during summer. The
district heating demand is controlled either with supplementary
firing during winter and transition periods or directly with
GT power during summer ensuring a high annual utilisation
factor for the selected power train equipment. The sensitivity
analysis has shown that is important to operate the new UNIT
on base load in order to achieve favourable tariffs for power
and heat.
The district heating demand from Bucharest South is sufficient
to utilise the new facility for most of the year at a very
high load. The power can easily be evacuated from the site,
preferably on the 110 kV network, by the existing switchyard
which is currently upgraded.
Back-up fuel, as required by the TOR, was thoroughly analysed
during the feasibility study and considered during the optimization
process but the economical analysis has shown that, with the
high distillate oil costs and the additional investment required,
under the given circumstances the most favourable plant configuration
is the single fuel option.
CONSTANTA PALAS CHPP
PROJECT
The prime objective of the CHPP is to supply the required
heat to the City of Constanta district heating network. Another
requirement is the supply of steam to industrial and internal
consumers during the summer period in which the existing power
plant is shut down. The electrical output then becomes a by
product to generate such heat requirement. Current high level
international price of natural gas which is the fuel for the
project makes it unfeasible to finance such investment as
a merchant plant. Therefore the investors, likewise in other
EU member countries, recommend that the project adhering to
the framework of the EU Directive 8/2004/EC to be able to
arise with an economically sustainable proposal.
The proposed plant configuration will consist of one small/medium
size gas turbine and one extraction-backpressure steam turbine.
This is the most economical solution even if supplementary
firing is necessary to achieve the required district heating
demand especially during winter season. With a gas turbine
size in the range of approximately 45 MW the plant can work
at base load for the entire year achieving a better efficiency.
The district heating demand is controlled either with supplementary
firing during winter and transition periods or directly with
GT power during summer ensuring a high annual utilisation
factor for the selected power train equipment. The sensitivity
analysis has shown that is important to operate the new UNIT
on base load in order to achieve favourable tariffs for power
and heat.
The district heating demand from Constanta is sufficient to
utilise the new facility for most of the year at a very high
load. The power can easily be evacuated from the site, preferably
on the 110 kV network, by the existing switchyard.
