Hi everyone,
please is it possible to forecast day ahead market prices for long term period 10-15 years. If yes, please could you recommend me where to find what is the mean absolute error for the long-term day ahead market prediction?

Dear Martina,
thank you for your message and interest in AMIRIS.
As scientists we must state that it is virtually impossible to predict electricity price dynamics over a long-term period. Day-ahead market prices are influenced by a multitude of variables, including but not limited to:
- Weather, climate and generation from renewable energy sources
- Electricity demand (load)
- Composition and availability of the (conventional) power plant fleet
- Fuel prices (e.g. oil, gas, hydrogen)
- Policies, support schemes, regulations
Over extended timeframes of decades, the abovementioned factors are challenging to quantify. Thus, any model will have a hard time to precisely predict (i.e. hourly) electricity prices.
However, if more abstract indicators suffice (e.g. annual average prices), one might derive some estimators from an extended scenario analysis with a wide parameter variation study. AMIRIS (among other models) can then be applied to estimate these indicators.
For backcasts, and short-term forecasts, where good estimators for the abovementioned factors exist, AMIRIS can perform quite nicely with an MAE of around 5 €/MWh.
For insights into historical performance, we recommend referring to our recently updated AMIRIS examples, which offer a comprehensive analysis of the German market zone from 2015 to 2019, benchmarking against actual historical prices.
Regards,
Christoph and Felix
