SUMMARY:

Backup thermoelectric power plants connected to the Brazilian grid commonly consume energy from the transmission networks when in stand-by mode. This consumption is valued according to the Price for Settlement of Differences (PLD), calculated by the Electric Energy Commercialization Chamber (CCEE). This work analyses the technical-economic feasibility of applying a concentrating solar power (CSP) plant combined with a small organic Rankine cycle (ORC) to replace the electricity consumed from the transmission network for a case study located in
Candeias, Bahia, Brazil. The methodology developed focus on the use of CSP as the main electricity source while the grid is used only when long periods without direct solar radiation occurs. The results indicate that the levelized cost of energy (LCOE) can vary between 6 and 80 ¢/kWh depending on CSP main components costs. This indicates that a reduction of 92% in the CAPEX is required for economic viability of proposed system, within scenarios whose remuneration varies in proportion to the PLD.
