The impact of weather and of batteries on the investment risk for backup gas power plants in a largely renewable energy system

With an increasing wind and photovoltaic share, the German generation mix becomes more weather-dependent. Backup technologies can help to bridge scarcity moments. These rare moments with high prices are the main events for their cost recovery. However, the uncertain revenue flow combined with long payback periods leads to high investment...

Aligning prosumers with the electricity wholesale market: The impact of time-varying price signals and fixed network charges on solar self consumption

PV-battery systems are currently not operated in an energy system optimal way as their operation heuristic (maximization of self-consumption) is generally unaffected by competitive market signals. To evaluate potential regulatory intervention, we propose a market alignment indicator which measures the relative economic efficiency of a prosumer...
