Look who's talking about us

The Way Energy Should Always Be

Ostrom uses tech to keep things lean, which means we can provide excellent customer service, transparency, flexibility, and the greenest electricity—without needing to markup our tariffs like other providers do.

Flexible & Fair Pricing

We sell our energy at cost because we'd rather our customers consume less, instead of more.

Genuinely Green

We sign with 100% renewable energy sources, meaning your power comes from the best places.
