Tradable green certificate (TGC) markets are economically driven policy instruments that can be used to increase investment in renewable electricity generating capacity. This type of policy increases revenue for renewable electricity generation units, making the units more cost effective in comparison to conventional electricity generation. An educational classroom game was created to simulate a TGC market, and was played twice with university students. Outcomes of the game varied substantially between the simulations. Strategies for playing the game were discussed with participants, and students were encouraged to analyze how these strategies affected the outcomes of the game. Players’ strategies were also used to extend each simulation past the number of simulation periods actually played, and to suggest ways to improve decision rules in system dynamics models of TGC markets.
