Traditionally, electricity markets have differed from other commodity markets for one specific reason – electricity can't be stored on a large scale. At least, that used to be the case.
In 2021, utility-scale battery and storage assets are coming onto the grid at an unprecedented rate. More than one gigawatt (GW) of battery storage was installed in 2020, which is twice the amount that was installed in 2019. This growth rate is expected to continue. EIA-860 data shows 10.9 GWs of capacity slated for development across 25 states.
Batteries solve the classic electricity problem, and they are expected to help balance supply and demand in real time. Recently, Plus Power won two bids in the ISO-NE capacity auction for 2024. This suggests new implications for batteries in nodal markets, as new capacity has normally been provided by small, fast-ramping gas units (Utility Dive).
As batteries come onto the grid and participate in the markets in new ways, it’s essential that all market participants understand how batteries are affecting the markets in this period of unprecedented change.
What This Means for Battery Developers
Battery developers need to ensure that they develop and install their assets in locations with significant volatility and an opportunity for arbitrage. To maximize profits, batteries should be charged during times when the grid is seeing lower pricing and discharged during times of high demand and increased prices. To ensure that this is possible, battery owners and developers will need a holistic view of the grid, including plant-level generation, pricing, congestion, and constraint data.
What This Means for Asset Developers and Operators
For asset developers, owners, and operators to stay competitive in these evolving markets, they will need to be aware of how batteries are affecting the markets and how batteries near their assets might affect them in particular. Questions to consider include:
- Will batteries cause volatility to drop?
- Will batteries bid traditional generation resources out of capacity markets?
- Will batteries solve the intermittency issues the grid is experiencing due to renewable penetration and make thermal generation obsolete in the long run?
What This Means for Traders
Financial traders also need to consider how batteries will impact the grid, as they, too, will be affected by any pricing changes. As the grid evolves, financial participants will have to keep an eye on how volatility is changing:
- Will it move to new locations?
- Will volatility decrease?
- Will the traditional periods of volatility change?
