Hybridizing peaking plants with battery storage can significantly reduce overall emissions in several ways:
- Immediate Power Provision: Batteries can provide power instantly, allowing peaker plants to ramp up more gradually and reducing the pollution emitted during startup. This is particularly effective for peakers, which often have high emissions when they first start up.
- Reduced Emissions During Restart: Hybrid systems can cut emissions by up to 60% during restarts, which are periods of high pollution. This is because batteries cover about half of the times when peaker plants need to restart, reducing the need for gas turbines to operate at low efficiency.
- Preventing Idling Emissions: Batteries can also prevent peaker plants from idling and emitting pollutants while waiting for power requests. Since batteries can respond instantly, they ensure that the peaker does not need to stay online unnecessarily, thus reducing idling emissions.
- Energy Supply Stability: Hybrid plants contribute to a more stable energy supply by addressing energy intermittency issues, which can indirectly support cleaner energy sources by providing a reliable backup.
- Compliance with Emissions Regulations: Hybridization can help peaker plants comply with stricter emissions standards by reducing localized pollution impacts on neighboring communities.
Overall, hybridization with battery storage is an effective strategy to mitigate the environmental impact of peaking power plants.
