Guidehouse has evaluated the effectiveness and efficiency of different national support programs in Switzerland and other European countries. On behalf of the Swiss Federal Audit Office (SFAO), Guidehouse analyzed four support schemes for electricity efficiency and renewable energy - both with and without an auction mechanism.
A direct comparison of the support efficiency of the programs is only possible to a limited extent, and subject to uncertainties regarding the operating periods and electricity price development. Overall, however, the efficiency of the electricity efficiency programs was generally higher than that of the renewable energy programs, regardless of whether the program was designed with or without an auction mechanism.
It thus became clear that auction schemes would not always ensure a viable competition and reduce the costs of funding.
In the report, the experts also identified the six most relevant factors that influence the effectiveness and efficiency of current support programs.
