EASE

Electricity ASset Evaluation

EASE enables the valuation of assets in electricity markets. It includes conventional (steam power plants) and renewable (PV, wind and biomass) power plants as well as storage technologies (water, pump and batteries), demand/conversion technologies (industrial production plants, power-to-heat, heat accumulators, etc.) and virtual power plants.

The model takes into account both technical characteristics and economic parameters of the asset as well as price-time series of the different electricity markets. Restrictions such as the need to cover heat consumption or technical constraints of, e.g., fermenters are explicitly considered in the model. The bidding strategies on the different markets are freely selectable, whereby collaterals by other assets or the utilization of the asset are represented in the portfolio. Variation of the bidding strategy, individual parameters or price developments can be simulated in different scenarios, which allows for a comparison of the results.

Results of EASE are the offered quantities, the achieved contribution margins as well as the resulting utilization of the asset. The results are broken down according to the different markets and available both in aggregated form, i.e., on an annual basis, and as a time series. Results can be presented in the form of developments over several years as well as in the form of aggregated revenues over a longer period of time.

Future price-time series for the day-ahead, intraday and control power markets are determined using the European electricity market model DIMENSION and fed into EASE via an interface.

Possible applications

Revenue calculation in the short, medium and long term

EASE identifies future revenues of assets (renewable and conventional technologies as well as storages) on the different electricity markets.

Utilization

EASE generates a market-optimal utilization profile of the assets on a detailed quarter-hourly basis.

Analysis of flexibility options

EASE enables the analysis and valuation of revenue increases with regard to both generation and consumption.

Bidding strategies

EASE allows the verification of bidding strategies by observing opportunities across the different markets.
