The total installed generating capacity on Crete consists of 490 MW of thermal plant and 67 MW of wind. On the Greek islands, maximum consumer demand occurs in the peak summer months of July and August, which coincides with maximum wind energy production. Maximum instantaneous wind energy penetration has been about 30% -- in December.
The overall monetary savings of operating wind power on Crete instead of relying on thermal generation are between 1.5 and 3%. The project also concludes that the wind plant benefit grid stability -- helping to stabilise grid frequency, without the need for large amounts of additional spinning reserve. The researchers anticipate achieving even better security and economic benefits through the installation of advanced control software.
