DISCHARGE WATER FLOW ESTIMATION MODULE - DFEM

CSE - Control Systems Engineer uses the original methodology for the assessement of the potential hydro
energetic of the river in Albania, using a discharge flow estimation module (DFEM) that calculates the monthly
discharge (surface and ground water) based on input variables such as monthly precipitation, intensity and
frequency of rainfall, snowfall, air temperature and solar radiation as well as regional specific discharge.

The monthly discharge simulations of this module help in a rapid assessment of the hydropower potential if no
observed discharge data are available. The module is designed as a lumped, deterministic rainfall-runoff
model. It is calibrated, validated and tested with observed discharge data from the Institute of Energy, Water
and Environment of Albania, AKBN, and the other international official sources, etc.
DFEM creates a relationship between the site discharge flow and the climate change factors to forecast the
discharge change in the future.

DFEM should apply with the others softwares and databases like FAO LocClime 1.1 software (www.fao.org),
SamSamWater (www.samsamwater.com), GAISMA database (www.gaisma.com), etc.

VJOSA RIVER CASCADE PROJECT - 397MW

CSE - Control Systems Engineer has prepared the keys of the project proposal for the assessement of the
potential hydro energetic of Vjosa river in the Southern part of Albania, using the discharge flow estimation
module (DFEM). The module is calibrated, validated and tested with observed discharge data from the
Institute of Energy, Water and Environment of Albania, AKBN, and the other official sources and publications.

The potential sites for the building and installation of new runoff hydropower plans with low dams (10-30m) at
the Vjosa river are identified and the expected annual average power generation is estimated. The effect of
future climate change on the power generation is also assessed. Totally, from El 310m asl up to El 13m asl,
there are planned to construct runoff hydropower plants in cascade with low dams, included Kalivac HPP, but
reconfigured like Dorza HPP to avoid the regional floods.

- Total power capacity of the cascade is 397 MW,
- Average annual power generation is 1,9450 GWh,
- Investment cost is estimated to 1.2 mld euro with specific invetment cost of 3000 euro/kW),
- Electricity cost is estimated rom 40 to 55 euro/MWh,
- Simple Payback is 10 - 15 years,
- Operation time 4500 hours/year.

NEW RENEWABLE ENERGY POWER PLANTS

CSE has prepared the feasibility study for the construction of the new renewable energy power plants in
Albania:

- Biofarm Ramilli 04 biogas power plant with a capacity of 50kW,
- Tirana Municipal Landfill gas LFG power plant with a capacity of 10MW,
- Fieri PV photovoltaic power plant with a capacity of 10MW,
- Tepelena windfarm power plant with a capacity of 10MW,

NEW HYDROMATRIX POWER PLANTS IN ALBANIA

Based on the propose, prefeasibility study & design prepared by CSE Engineering, ANDRITZ VATECH Hydro
had expressed the interest to construct a new straflomatrix power plants at downstream of Drin River in
Northern of Albania with a capacity of 68MW and an annual power generation of 350GWh. On 30 September
2008 was signed the Concession Contract between Verbund Austria & Albanian Government for the
construction of Ashta I & II hydropower plants with hydromatrix units, capacity 50MW and an annual energy
generation of 240GWh.
