AlphaESS battery systems form a key part of the Octopus Zero Bills Homes programme. This ground-breaking initiative enables new homeowners to live with no energy bills for up to 10 years*. By integrating renewable technologies, including solar generation, battery storage, and smart tariff technology, property developers can deliver homes that are not only sustainable but also more attractive to buyers, achieving faster sales and potentially higher property values.

How It Works for Developers
