Abstract (EN): There are two recognized tendencies in electricity markets: the development of spot markets and the increase of renewable electricity generation. These tendencies create dynamics in both price and volatility. In Portugal, there are powerful support schemes for renewable electricity. Therefore, the main sources for generating electricity in Portugal are renewable. This paper analyzes ex-post the impact of energy produced in special regime on the wholesale hourly spot market prices of Portuguese electricity during the period 2009-2016. It finds that special regime generation has a negative impact on the wholesale price. Effectively, an increase of special regime generation by 1.0 GWh, all else being equal, reduces the wholesale spot price by 3.9 (sic)/MWh. This represents 8.6% of the average wholesale price. Moreover, the substitution of 1.0 GWh of coal generation for special regime sources has an impact on electricity spot prices of, on average, -15.96 (sic)/MWh. This paper also concludes that using special regime generation to supply the future growth of demand will decrease wholesale electricity spot prices more intensively than using other technologies.
