PROJECT FOR SUMMER SOURCE - THE BIOMASS PLANT

CET Govora Oct 2011

The yearly deliveries of the biomass plants will be:- Heat = 120.000 MWh;

- Electricity = 34.000 MWh;The yearly biomass demand 81.500 tons

1. The wood availabilities in an area of 150 km are of 120.000 t/year wood wastes fromwood industries

2. During the 3 last years some quantities of biomass were coincinerated with coal in the coal boilers:- year 2008 = 40.000 t- year 2009 =16.000 t- year 2010 = 12.500 t

3. The investment is mandatory by the strategy for DH of the city Rm. Vâlcea.

4. The investment in the plant and annex facilities (biomass storage, grinders, transporters) is estimated at 22.5 mil euro and is feasible until december 2013; the repay of the credit will be

realised by selling the green certificates on the market, in aproximatively 5 years after start up.
