Again, not different here... Fonte: PDE 2022 (http://epe.gov.br/pdee/20140124_1.pdf). Larga expansão de capacidade instalada de fontes sazonais e/ou intermitentes no sistema elétrico brasileiro, com destaque para a fonte eólica (+15GW). Novas usinas hidrelétricas (+36GW) usarão o conceito de fio d água, não havendo nova capacidade de armazenamento, sendo a maioria a ser instalada na Amazônia. O Brasil perderá, ao longo dos próximos anos, a capacidade de armazenamento das hidrelétricas que possui. Haverá redução na relação entre energia armazenável e carga. Incerteza quanto as hidrologias futuras no NE brasileiro. 17 Wärtsilä 15 May 2014 The Role of Flexible Power Plants/ Wärtsilä Brasil
GHG emission targets Typical target for year 2020, e.g. EU and USA: 20% energy share from renewable sources 20% less greenhouse gas emissions 20% increase in energy efficiency 20 % renewable energy in 2020 means 5-7 times more wind power capacity in the EU! Wind power capacity will greatly exceed average load System operation and operation profiles of thermal plants need to change Variable wind power and larger day/night load variations increase demand for dynamic flexibility of generation assets It is generally agreed that security of supply is at risk, but there has not been any perceived solution Present electricity markets are generally based on selling energy (kwh s) and do not reward dynamic flexible capacity adequately to encourage investments New parallel capacity markets must be developed to enable private investments in fast, flexible system balancing capacity (kw s) 18 Wärtsilä 15 May 2014 The Role of Flexible Power Plants/ Wärtsilä Brasil

System impact of wind power Source: Vestas Reaching 20% renewable power requires approximately 285 GW of installed wind capacity in the EU A wind speed change from 9 -> 7 m/s could change wind power output with ~100 GW. Such wind speed changes are barely notable and happen all the time. 20 Wärtsilä 15 May 2014 The Role of Flexible Power Plants/ Wärtsilä Brasil

Main topics for discussions There is no magic solution; Impacts (in Brazil) of intermitent and stochastic generation needs further study and developments; More fluctuations in load and generation will require more system flexibility; State-of-art forecast methodologies are a must; Planning of the operation has to be adapt; Planning of the expansion has to adress the value of flexibility; Auction process requires constant update; 28 Wärtsilä 15 May 2014 The Role of Flexible Power Plants/ Wärtsilä Brasil
