Optimal ESS Solutions Under European Electricity Pricing Policies and Subsidy Mechanisms
In Europe, electricity pricing policies and subsidy mechanisms are actively driving large electricity consumers to establish their own "self-sustaining power plants." By adopting the photovoltaic (PV) + energy storage self-consumption model, these consumers can significantly reduce electricity costs. This trend not only reflects Europe's strong commitment to renewable energy but also highlights the unique advantages of distributed energy storage systems in the current electricity pricing structure.
Electricity Pricing Structure and Energy Tax ReliefAccording to the Bruegel 2024 report, the electricity pricing strategies across European countries vary in terms of the proportions of purchase price, network fees, energy taxes, and VAT. These differences can cause significant fluctuations in electricity prices across Europe, impacting the electricity costs for businesses and potentially leading to instability in cross-border electricity markets. In the context of the energy crisis and green transition, these price differences are even more pronounced and could undermine market competitiveness.
The main components of European electricity prices include purchase prices, network fees, energy taxes, and VAT, typically with a roughly equal distribution of 1:1:1. With the use of new energy sources like PV + energy storage systems, energy tax relief can be obtained. By using self-generated electricity, users not only reduce their need to purchase electricity from the grid but also lighten their energy tax burden, thus significantly lowering electricity costs. This provides a crucial economic incentive for users adopting PV + energy storage systems.
Energy Storage System’s Role in Time-of-Use OptimizationAs the share of renewable energy sources such as wind and solar power continues to rise, the amount of renewable energy generation fluctuates significantly. During times of high renewable energy generation, the electricity price on the grid is usually lower, and energy storage systems can play a vital role by shifting energy consumption. Users can store excess electricity during periods of low prices and release it during peak pricing periods, further optimizing electricity costs and reducing overall energy expenditures. Therefore, PV + energy storage systems not only increase energy self-sufficiency but also enable further optimization of electricity costs through smart scheduling.
Price Differentials and Negative Pricing PhenomenonIt is noteworthy that the price differences between buying and selling electricity vary greatly across European countries. In some countries like the Netherlands, the buying and selling price ratios are relatively close, while in others, the differences are quite large. This means that users with PV + energy storage systems can earn higher returns by selling electricity during periods of high prices.Additionally, the phenomenon of negative pricing frequently occurs in Europe. During peak wind or solar power generation periods, when grid voltage and frequency are high, there may be an excess of electricity supply. Negative pricing means that users can actually receive compensation for consuming electricity during these periods, while feeding electricity back into the grid may result in fines. Therefore, for users with PV + energy storage systems, adjusting electricity supply through storage systems to avoid feeding electricity into the grid during negative price periods is an effective way to reduce electricity costs.
