Three distinct yet interlinked dimensions can illustrate energy storage’s expanding role in the current and future electric grid—renewable energy integration, grid optimization, and electrification and decentralization support.
The effectiveness of an energy storage facility is determined by how quickly it can react to changes in demand, the rate of energy lost in the storage process, its overall energy storage capacity, and how quickly it can be recharged. Energy storage is not new.
We estimate that cost-competitively meeting baseload demand 100% of the time requires storage energy capacity costs below $20/kWh. If other sources meet demand 5% of the time, electricity costs fall and the energy capacity cost target rises to $150/kWh.
Energy storage growth is generally driven by economics, incentives, and versatility. The third driver—versatility—is reflected in energy storage’s growing variety of roles across the electric grid (figure 1).
A reasonable allocation of energy storage ensures the safety support of thermal power for system operation and reduces the operational hours of thermal power units. This mechanism contributes to solving the issue of large-scale renewable energy curtailment.
As storage energy capacity costs increase, the solar power plant size increases (B), optimal storage duration decreases (C), and storage power capacity relative to output power increases (D). Solar cost of ownership is estimated as $1,000/kW for all three cases, and the EAF is 100%.
