Heat supply strategy for Comanesti Town
Short description:
The main goal of the documentation was the performance of heat supply strategy for Comanesti Town in compliance with the requirements of Investments Programme “Termoficare 2006-2009 – calitate şi eficienţă”, with the purpose to improve the efficiency of DHS in Comanesti Town.
Technical solution for the thermal energy source was established through a comparative analysis of possible solutions and consists in:
- 2 Heat engines: 2 x 2,4 MWe (total heat recovered: 2 x 2 Gcal/h), running on natural gas, which will mainly supply the domestic warm water.
- 2 heat boilers: 2 x 5 Gcal/h running on biomass (wood wastes) and natural gas, for heat demand.
- 1heat only boiler: 1 x 10 Gcal/h running on natural gas, for heat demand.
In accordance with the optimal solution for the CHP Plant, were been considered measures needed to be adopted for the transport and distribution networks, and thermal stations.
There were also assessed the measures at the lever of end-user, as follows:
- implementation of metering at the flats;
- changing the distribution conception in the apartments’ (from horizontal to vertical) and the implementation of individual metering;
- thermal rehabilitation of the buildings.
Services offered:
The proposal of a strategy for supplying with thermal energy the consumers in Comanesti Town for the next 20 years.
Estimated technical performances:
Average annual performances during the period of analysis:
- Heat delivered: 60194Gcal/year.
- Electric power delivered: 28406 MWh/year.
- Fuel consumption: 15618 tcc/an, from which: - Natural gas:12888 tcc/year; - Biomass: 2730 tcc/year;
- The efficiency of cogeneration: 81,4%.
Estimated economic efficiency:
Financial analysis of the investments, concludes to the followings:
Cash-Flow is positive during the period of analysis.
The prices of the electricity and heat which will cover the overall annual operation costs of the DHS are:
- 57,22 Euro/MWh for electricity delivered.
- 43,78 Euro/Gcal for heat delivered.
These prices lead to the Net Present Value of 1324312 Euro and the rate of profit of 5%.
