Asset costs view (€/h)

indexed by: asset, node, revenue_type, technology and test case

Description

The KPI computes the costs incurred by the operation of each asset of the realization. Asset costs are calculated as the sum of :

• System costs of each asset such as computed by associated KPI (see System costs view)

• Costs associated to energy consumption

• Costs associated to CO2 and CO2 captured production

Calculation

The equation below is valid for any realization and is therefore implicitly indexed by test case.

Let be \(x_{a, n}\) the asset costs of asset \(a\) at node \(n\). We can then express \(x_{a, n}\) as:

\[x_{a, n} = sc_{a, n} + energy\_consumption\_costs_{n, a} + co2\_production\_costs_{n, a} + co2\_captured\_production\_costs_{n, a}\]

Each cost is calculated as follows:

System costs

These costs are the same as the one returned by the corresponding System costs KPI. They represent the costs of operating an asset \(a\) from a system point of view spread equally between the nodes to which \(a\) is connected.

Energy consumption costs

These costs represent the costs of buying all the energy the asset consumes on the corresponding markets. We can therefore express them as:

\[energy\_consumption\_costs_{a, n} = \frac{1}{N_a} \cdot \sum\limits_{e \in E} \sum\limits_{n' \in N^c_{a, e}} c_{a, e, n'} * mc_{n', e}\]

Where \(mc_{n, e}\) represents the marginal cost of energy \(e\) at node \(n\).

CO2 and CO2 captured costs

These costs represent the costs of emitting CO2 or CO2 captured. We can therefore express them as :

\[co2\_production\_costs_{a, n} = \frac{1}{N_a} \cdot \sum\limits_{n' \in N^p_{a, CO2}}p_{a, CO2, n'} * mc_{n', CO2}\]

And

\[co2\_captured\_production\_costs_{a, n} = \frac{1}{N_a} \cdot \sum\limits_{n' \in N^p_{a, CO2\_captured}}p_{a, CO2\_captured, n'} * mc_{n', CO2\_captured}\]

Comment on the absence of energy indexing

All costs of a given asset must always be considered together not depending on their energies, since some costs are shared. For instance, in the system cost part of the asset cost, the runningCapacityCost is linked to the electricity production as much as to the reserve production. Therefore, indexing these costs by energy would be misleading. See the documentation of System cost for more details.

Costs shared between nodes

Additionally, as an asset could produce or consume energy at several nodes. For practicality purposes and to share costs between those nodes, the whole system cost of an asset is equally divided between the nodes for which the asset is linked. Then, for instance, a transmission between the nodes A and B will see its asset costs equally shared between A and B.
