E102: An airbag for the electrical grid

Continuing our Smart Grid Series, we zoom in on reliability — because building more solar and wind doesn’t matter if the grid itself can’t stay stable. We’ve seen what happens when it fails: blackouts in Spain and Portugal earlier this year, near misses in Texas, rolling outages in California.

My guest is David Hebert, VP of Global Sales & Business Strategy at Wärtsilä Energy Storage. Wärtsilä is a 190-year-old company that now builds integrated storage systems combining hardware + software to keep grids reliable — even in moments of stress.

We dive into:

• Why grid operators need fast, flexible tools beyond just generation
• Synthetic inertia: batteries mimicking the stabilizing effect of spinning turbines
• How storage can act like an “airbag” — catching a wobble before it cascades into blackout
• Real-world deployments: from the UK’s Blackhillock project to island microgrids in Bonaire & Graciosa
• Reliability + resilience: sectionalizing grids after hurricanes, blackstart capability, and non-wires alternatives
• Enabling more renewables by smoothing intermittency and curtailment issues
• Why batteries are the “Swiss Army knife” of the grid: frequency regulation, voltage support, time-shifting, backup power
• Cost, customer adoption, and how utilities are (finally) moving past reflexive resistance
