- Reducing the energy production costs for peak and intermediate load by substituting fossile power plants through hydroelectric and windpower
- Efficient energy storaging of exceeding wind energy by a pump-storage unit
- Integration of renewable energies in weak islands grids
- Reducing of emissions (in particular CO2) of fossile power plants by windturbines and hydroelectrical power plants
- Integration of pump storage plant in the environment of arid islands by using a closed water circuit and desalination by reverse osmosis
- Avoiding stabilisation problems by wind power in weak island grids.
1. Energy production costs (ECU/kWh) of wind turbines in combination with pump storage power plant 20-30% lower than energy production costs for gas turbines.
2. Integration of renewable energies in weak island grids without stability problems for the grid.
3. Implemenattion of the experiences and the know-how in further projects in similar regions.
The Hellenic Energiekontor is planning a 15 MW windfarm (10 units of 1,5 mW) at the Monastery Epanosifi on Crete. The mountain near the monastery has promising wind conditions which allows low generation cost. The latest technology with 1,5 MW machines will be used to minimize investment and generation costs. Within this project the wind farm will be combined with a pump storage power plant (5MW) with a closed water circuit. Losses due to evaporation will be replaced by desalinated seawater due to reserve osmosis. The reason for linking the wind power plant to the pump storage plant is the following : During the night the base energy load of the grid has its minimum (about 100/140 MW) and is generated by steam units fueled by heavy oil. The intermediate and the peak loads are generated by gas turbines. During the nighttime (about 8h.) the wind units can not operate because of problems relating to the stability of the grid which make it necessary to turn off the wind power plant. This circumstance would cause a loss of 33% of the possible wind power production and consequently increasing costs for wind energy production.
A pump storage power plant gives the possibilities to store the exceeding wind energy druing the night and to supply power during daytime as intermediate or peak loads. This causes better performances of the windfarm, lowers energy production costs for windfarm and peak and intermediate load and reduces emissions (CO2) due to fossile power plants.
INNOVATIVE TECHNOLOGY :
The whole concept of the combined wind park/pump storage unit is in so far innovating as it could open application in market, where the meteorological and geological conditions are given, but limitation to the isolated networks regarding the generated power is existing. Potential areas could be islands of the Cyclades in Greece or the Canary islands. The development of standardised modules could also reach to the exploitation of smaller and bigger potentials.
