This thesis empirically investigates the impacts that the implementation of tradable certificate scheme along with the quota obligation has had on the end user price of electricity in Sweden. It also empirically investigates what effects an increased sized quota obligation has had on the production of renewable electricity in Sweden. The study uses ordinary least square technique (OLS) to test the relationships of interest. Theoretical assumptions are derived mathematically and this is used as a foundation to for the OLS regressions. Conclusions that can be made from this thesis is that an increased (1 %) sized quota obligation will cause the production of renewable electricity to increase (0.44 %). It also shows that the end user price will be positively correlated with the size of the quota obligation.
