Slide 3: Introduction
Introduction Endesa is the sole production, transmission-distribution company in the Balearic Islands. It also sells gas. It acts as a supplier in the deregulated market. The Balearic Islands have two independent, isolated electricity systems: Mallorca-Menorca, with 1,365 nominal MW installed and Ib

Slide 15: Key parameters
Key parameters FREQUENCY periods by second (Hz) electrical pressure throughout entire network, especially with customers VOLTAGE electricity companies are obliged to keep these prices at their nominal valueQUALITY
Slide 16: Isolated vs extensive system
Isolated vs extensive system It is not the size of the key parameters which define the system but rather its variations compared to unbalances in the network. A 40 MW interruption produces a frequency change of: Mainland: 0.015 Hz Mallorca-Menorca: 0.80 Hz The difference between both systems is over
Slide 17: Result of previous unbalance in the isolated systems
Result of previous unbalance in the ISOLATED SYSTEMS ... o o o 49 Hz 48.8 Hz 48.6 HZ Very low utilisation factor (43% in 2005) In order to offset this deficiency: Primary reserve (margin in each generator) Secondary reserve (higher variable cost of generator margin) Third reserve (group stopped) GEN
Slide 18: Conclusions
Conclusions o Sharp frequency changes for the same load is around 55 higher than on the mainland o The loss or surge of a generation group almost inevitably means easing the load o Any change in the network frequency leads to capacity changes in the groups (no fewer than 30 incidents a year)

Slide 20: Supply quality
Supply quality The Balearic Islands, which mainly depend on tourism, are very sensitive to their international image and, therefore, the quality of its basic services The Interruption Time should be no higher than on the mainland although there, only T+D contribute to this whereas in the islands, ge
