Does increasing self-generation and self-consumption affect electricity price components?
This development will have a large impact on the share of energy purchased from the electricity grid and this, in turn, will affect the distribution of the cost components of the household electricity price. This contribution therefore analyzes the impacts of increasing self-generation and self-consumption on the electricity price components.
How do self-consuming households affect electricity prices?
An increasing number of self-consuming households leads to increasing household electricity prices due to two effects. Firstly, households where PV systems are installed with a battery system still feed surplus energy into the grid, which is remunerated with guaranteed feed-in tariffs.
Can energy storage technology help a grid with more renewable power?
Energy storage technologies with longer durations of 10 to 100 h could enable a grid with more renewable power, if the appropriate cost structure and performance—capital costs for power and energy, round-trip efficiency, self-discharge, etc.—can be realized.
What are the economic implications of grid-scale electrical energy storage?
Energy storage can diminish this imbalance, relieving the grid congestion, and promoting distributed generation. The economic implications of grid-scale electrical energy storage technologies are however obscure for the experts, power grid operators, regulators, and power producers.
Why do electricity prices increase so much?
While grid charges increase by 5.3%, the total electricity price increases even more strongly by 16.5%. This is mainly caused by a drastic increase of the renewable energy levy of 54% due to high additional PV feed-in.
Why do electricity prices increase based on capacity based grid charges?
The higher share of the increase in this scenario is caused by additional PV-feed-in remunerated by feed-in tariffs. If only self-consumption is considered, the maximum electricity price increase is 6.3% in a scenario with capacity-based grid charges.
