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.
