Typically yearly traded volumes and prices of intraday power exchanges and imbalances are used to analyse the market performance. This study introduces two indicators to measure efficiency in intraday electricity markets. The efficiency is measured during hours of high deviation of actual and forecasted residual load. The results of the analysis show non-complementarity of activated balancing energy to forecast deviations, thus pointing to an inefficient market. As the power plant generation mix cannot sufficiently explain the intraday market inefficiency, further research regarding imbalance regulations and incentives as well as forecast information deferral and OTC trading practice is needed.

In the German context, investments in power plants have been realized since liberalization. It is however unclear whether these investments were actually driven by electricity market price signals or by other factors such as the free allocation of CO2 allowances. The main doubts regarding the functioning of energy-only markets regarding investments is based on the missing-money problem: Necessary peak prices in situations of scarcity cannot occur due to politically set or technical price caps and thus financing of fixed costs is not possible especially for peak load plants. The increasing share of renewables in the electricity sector aggravate the missing money problem as technologies with close to zero marginal costs decrease both peak prices and average electricity market prices (‘merit order effect’). Current s...

In recent years, auction schemes for the allocation of support for renewable electricity sources (RES) have been advancing rapidly across Europe. Auctions are considered to have brought down support levels and increased planning capability for RES deployment and state budgets. In some unfortunate cases, they have, however, also resulted in delayed or unrealised projects and increased uncertainty for project developers. A variety of auction designs are still being tested and introduced in EU MS, as well as foreseen by European legislation. Therefore, there is still a need for further assessment and improvement of national auction design and implementation to ensure the future success of RES auctions in Europe. Applying different qualitative and quantitative methods in the various work packages (WPs), the AURES II project partners have already...
