Balancing the electrical grid in unexpected situations

A power plant using containers with second-life EV batteries could have helped avoid today's power outages in Spain and Portugal by:

  1. Frequency and Voltage Stabilization
    • Batteries can instantly (within milliseconds) deliver or absorb electricity.
    • When grid oscillations occur (as they did today), battery systems can quickly smooth out fluctuations, prevent grid failure, and give operators time to rebalance the system.
  2. Black Start Support
    • If the entire grid collapses, a power source is needed that can start conventional plants (thermal, hydro) from scratch.
    • Battery power plants can act as black start solutions by immediately supplying electricity needed to start large generators.
  3. Microgrids for Critical Infrastructure
    • In a full grid collapse, battery containers can maintain local operation of hospitals, communication hubs, traffic control, etc., until the broader grid is restored.
  4. Rapid Deployment and Flexibility
    • Containerized battery systems can be quickly relocated and installed wherever emergency support is needed.

How many containers would be required?

  • A typical container using second-life batteries (e.g., from Tesla Model S/X) can have 1–2 MWh capacity.
  • Large battery power plants have capacities of 100–250 MW and 200–500 MWh.

To stabilize a national grid during a major disturbance, you'd need:

  • 200–400 MW instantaneous power,
  • and at least 400–800 MWh capacity to sustain delivery for 1–2 hours.

Calculation:

  • One container = ~1.5 MWh (average)
  • For 600 MWh → approximately 400 containers

Conclusion:

  • Serious national support (e.g., Spain or Portugal) needs around 300–500 containers.
  • Local stabilization (e.g., Madrid or an industrial zone) could use 50–100 containers.

Note:

  • Second-life EV batteries retain around 70–80% of original capacity.
  • Their performance and lifespan are reduced, so oversizing is required for long-term reliability.
