In countries that get electricity from coal or oil, power dispatch is done “locally” and is conceptually a simple matter • The dispatcher ranks the generators by unit price
In countries that most of the electricity is generated by hydro plants, hydrological uncertainty is a relevant issue Future Today Time • Future water storage depends on present storage, future water inflow and the decision about how much thermoelectricity could be substituted by hydroelectricity
Reliability Energy buyers (distribution companies & free consumers): 100% of the energy consumption should be contracted through PPAs Energy sellers (generators) ∑ PPAs < calculatedfirm energy
New power plants are built if their proponents win Government organized auctions of PPAs Energy producer 1 Disco 1 Disco 2 Energy producer2 ... ... Energy Producerm Disco n
Centralized dispatch • In order to take advantage of hydrological diversity, energy is transported through long distances • Hydropower plants in the same river basin are own by different companies • Hydropower plants share the joint production proportionally to the firm energies
Three contemporary regulatory problems How to incentive the existing hydropower plants to be transparent, innovative and efficient? Regulatory activism X Regulatory stability How to allocate the energy theft and delinquency cost between the Discos and the honest consumers?
