Samba Solar Developments’ Partner and Technology Lead Michael Neswal explains the importance of grid extension for the planned shift in Brazil's energy mix: If a country plans to decentralize energy production, the transmission grid transformation is equally important to this process as is the generation function.
In order to plan for the grid development, Brazil’s energy agency EPE (www.epe.gov.br/) had to take into account the projected growth in usage (demand) and match this to the expected change in generation (supply) and derive a plan under standard design rules (criterion n-1) to make sure all generation and usage is connected all the time. This is quite the challenge for Brazil, given the fact that the county is in the process of auctioning some of those transmission capacities in order to explore best market prices. The main results of these studies can be found in the Brazilian 10-year plan PDE in chapter 4, which can be found here (https://lnkd.in/dZqKxPC7). In the end Brazil will add up to 40GW of renewable generation capacity. The real challenge for the country is, that this expansion needs to be anticipated and planned to some extend or to put it in other words, there will be no renewable generation without grid connection. Within the study mentioned above the EPE also investigates storage technologies in order to stabilize usage patterns as well as the influence of interconnect to neighbouring countries like Argentina or Paraguay. An important concept included here is nodal pricing (https://lnkd.in/dgMVHYJX) for pricing of transmission services, which in the end is supposed to favour generation projects outside the big centres of energy demand. The evolving energy structure in Brazil will be very interesting to watch and Samba Solar Developments GmbH is looking forward to support this unique process and opportunity and has teamed up with excellent partners in Brazil as well as with renown experts with in the industry.
