Utility-scale batteries can influence peak electricity prices by storing energy during periods of low demand and releasing it during peak hours when demand is higher. This ability to shift the timing of energy supply can help stabilize electricity prices in several ways:
- Price Smoothing: By injecting power into the grid during peak demand periods, utility-scale batteries can reduce the strain on traditional power plants, potentially lowering peak prices. They can buy energy at lower prices when demand is low and sell it during periods of high demand, which can help reduce price spikes.
- Reducing Peak Demand: If utility-scale batteries can provide a significant portion of the energy needed during peak hours, they can reduce the overall peak demand on the grid. This reduction in peak demand can help mitigate price volatility, as the grid is less strained by extreme demand levels.
- Market Dynamics: However, the overall impact on price volatility might be limited. While batteries can help manage peak periods, they might not significantly reduce overall volatility in day-ahead markets. The effect of batteries on reducing price spikes could be bounded by their capacity and the dynamics of energy markets, which are influenced by many factors beyond just storage capacity.
In summary, utility-scale batteries can contribute to stabilizing electricity prices by managing supply during peak demand periods, but their effectiveness in significantly reducing overall price volatility is still a subject of debate.
