this paper discusses how the issue of supply adequacy is treated in the Brazilian power market, analyzing lessons learned from past experiences and describing the solutions that are being implemented to reconcile competition in generation with an adequate supply.Index Terms--Power system economics, power system planning, hydroelectric power generation.

Integrated Natural Gas-Electricity Resource Adequacy Planning In Latin America

“…The main objectives of this new model are to provide more secure conditions for investors and assure security of electricity supply. A review and assessment of this power sector model are provided in greater detail in [2,3] and in Chapter 17 of this book. Its main highlights are: (a) every load (regulated plus deregulated consumers) must be covered 100% by bilateral financial contracts at all times and all contracts must be "backed" by firm energy certificates; and (b) Discos must contract their energy through public Power Purchase Agreements (PPA) auctions, with standardized rules and contracts of different maturities.…”

Hedging Renewable Energy Sales in the Brazilian Contract Market via Robust Optimization

“…Sector reform brought about 85% of total regulated load privatization and the transmission expansion had been carried out with strong participation of private agents. However, due to political opposition, the privatization of power generation companies resulted in only 15% of total generation capacity, being appointed to be one of the main reasons for the 2001-2002 supply crisis that affected all consumers around the country [17].…”

“…A collateral effect of such centralized dispatch is the high volatility pattern of the short-run marginal cost (which is, ultimately, the energy spot price) and its strong correlation with the system's inflow [17]. Since the system is designed to withstand under very harsh conditions (by means of an overcapacity in power and energy), in most of the time it has an excess of recourses to meet the demand.…”

Strategic Risk Management: A Framework for Renewable Generation Investment Under Uncertainty

“…67 5.1 DCIDE contracts and their respective maturities on the week beginning in 03/21/2016. 76 5.2 Spot and forward contract prices. 77 5.3 Spot and forward contracts.…”

“…Forward contracting plays several major roles, such as ensuring supply adequacy (102), (76), inducing adequate economic signaling for investment and network expansion (37), risk management of cash ows (8) and marking to market one's position (59), and also reducing market power of agents (106),…”
