USE OF THE THEORY OF GAMES AS AN INNOVATIVE METHOD IN THE SOLAR ENERGY INVESTMENT DECISION PROCESS

Brazil is a country with high solar energy potential due to the vast unhabitaded areas close to the Equator with high availability of solar radiation. With a simple setting, low maintenance costs, sustainability appeal and an inexhaustible power supply, the solar plants have been transformed in attractive investments in the electrical power sector.  In the Brazilian Northeastern region, it's possible to find the best conditions for the development of new solar plants due to the climate, dry and sunny all year. The present work aims to present the use of game theory as an innovative method in the investment decision process between two companies of solar energy generation in Northeastrn region of Brazil. The methodology used for this analysis was the Cournot method to conclude whether competition or cooperation among the agents involved prevails in the market.
