Considerations on the Green Certificate Support Dystem for Electricity Production from Renewable Energy Sources

摘要

Use of renewable energy sources is promoted across European Union by support schemes that are applied in order to achieve energy policy goals of sustainability, security of supply and improved competitiveness. The paper presents in a synthetic manner the evolution of the support scheme of quota obligation system with tradable green certificates in Romania. Also, it is analyzed the profitability of the support scheme as a result of reducing the number of green certificates and the trading price of green certificates. The cost-benefit analysis is achieved compared in three situations: the situation at the beginning of the support scheme and the maximum sales price of green certificates; the situation at the beginning of the support scheme and the minimum sales price of green certificates and nowadays situation after the reducing of the green certificates number and the minimum sales price.
