Despite some advantages, renewable sources pose certain financial risks for investors in the industry. These risks are mainly associated with the oscillation of energy production, the prices and rules of the energy market, and the possibility of delays and anticipations at the conclusion of works. In order to mitigate the likelihood of low power production, distinct sorts of power sources have been combined into one integrated system so that you may take advantage of source complementarity and network asset sharing. This work studies the financial risk associated with the anticipation or delay in the completion of projects in the Brazilian energy market considering the insertion of photovoltaic sources in an integrated wind-solar power plant. To evaluate the project feasibility, Net Present Value is used as deterministic method and Monte Carlo Simulation is performed as stochastic valuation model through some historical data obtained. The economic risk assessment showed that delayed works significantly increase the probability of a failed business regardless of the proportion of the sources in the integrated system. Projects finished earlier, in contrast, increase the chances of a profitable business, although this increase is less significant in systems with lower installed photovoltaic source and more relevant to systems with a higher proportion of integrated solar source.
•Delayed works sharply reduce the likelihood of a protable business for any scenario•Works concluded in advance contribute to a thriving undertaking•Works concluded in advance are more signicant for certain scenarios•The likelihood of positive NPV drops as PV power is inserted into the system
